U.S. Oil Deal in Syria Angers the Kremlin
THE KURDS GET THEIR WAY

18 August 2020 Ksenia Svetlova

In early August, the U.S. firm signed a surprise deal with the Syrian Kurds to revamp oil fields in northeastern Syria. The deal clearly irritated Moscow, which doesn’t hide its intentions to gain control over oil production in the country and prop up Bashar Assad’s heavily oil-reliant regime. As the Syrian economy continues to deteriorate, U.S.-Russia tensions in the region are likely to grow.

About two years following the U.S. announcement to withdraw from Syria, American oil companies based in the northeast of the country continue to operate and sign agreements with the Kurdish leadership of the Syrian Democratic Forces. Both Syria’s Bashar Assad and his Kremlin backers are not happy.

Russia’s gaining control over the northeastern regions of Syria would signify control over the entire country, weaken other players, and open up access to rich natural resources such as gas, oil, and phosphates. In addition, the Kremlin lusts after the important transport hub located in this area, which is used both to export Syrian gas to Europe and to connect trade routes between Iran, Iraqi Kurdistan, Turkey, and Syria. As of now, all of these advantages remain out of the Kremlin’s reach.

It is, perhaps, for these reasons that when, in early August, the U.S. company Delta Crescent Energy LLC signed a 25-year-long agreement with the Syrian Kurds to modernize the oil fields in northeastern Syria, the news provoked a particularly angry reaction from the Kremlin. According to media reports, one of the clauses in this deal prohibits the Syrian Democratic Forces from sharing profits from oil production with Assad’s regime (which remains under U.S. sanctions).

Russia’s permanent representative to the UN Security Council, Vassily Nebenzia, once again called on the U.S. to end its “occupation of the Syrian oil fields,” and accused it of using “barbaric methods [of oil production] that could lead to an ecological disaster in northeastern Syria and Iraq.”

Profits from oil production in northeastern Syria are currently estimated at about $40 million per month. The United States has no intention of handing this source of income over to the Assad regime. To protect the oil fields in the region, it is building special units that include the Kurds, the Arabs (cooperating with the Syrian Democratic Forces), and the Kurdish People’s Protection Units (YPG), whose purpose is to fend off the attacks of pro-Iranian militias operating in the oil-rich province of Deir al-Zour in eastern Syria.

Most of the Syrian oil is in fact concentrated in the northeastern parts of the country, which are controlled by the Syrian Democratic Forces. In 2011, the Al-Omar field—Syria’s largest oil field—produced about 80,000 barrels of oil per day, with about 40,000 barrels added by the Al-Tanak field. The two largest fields in the Deir al-Zour and Al-Hasakah provinces rendered about 200,000 barrels of oil per day, or roughly half of all oil production in Syria.

Oil revenues are Syria’s main source of income. In 2008, oil production in the country peaked at about 406,000 barrels per day, but by 2018, as a result of the war, it had dropped to only 24,000 barrels per day (not accounting for the black oil market).

During the war, most of Syria’s oil resources came under Kurdish and American control. This turn of events had serious consequences for Iran, which failed to retain control over the Al-Qa’im border crossing—one of the major supply routes across the Middle East. As a result, transportation flows between Iran, Iraq, and Syria have been disrupted. In addition, Iran is now facing Russian competition for lucrative energy contracts with Damascus, and Russian oil companies have already been granted exploration rights in Syria’s internal waters. The Syrian Ministry of Energy estimates its offshore gas reserves at about 250 billion cubic meters. However, as Lebanese experience has recently shown, exploration rights do not necessarily translate into profits.

What are the possible scenarios regarding the fate of the oil fields in northeastern Syria?

Clearly, Russia will not give up its efforts to help Bashar Assad regain control over the northeast of the country—both to get access to the oil fields and to stabilize the Syrian economy. However, the U.S. presence in the region and its willingness to defend the oil fields together with the Kurds signal that the current U.S.-Russia friction in Syria will intensify. Last time Russia tried to take over oil fields in the northeast was in 2018—a failed attempt that resulted in the U.S. killing of several hundred Russian mercenaries. As the Syrian economy continues to deteriorate, Russia might make another try.

A Russian takeover of Syria’s northeastern regions (about a third of the country’s territory) is possible only in two cases: if the U.S. decides to end its presence and withdraw its troops from this area or if the interested parties—including the Syrian Democratic Forces, the central government in Damascus, and its Russian partners—reach an agreement as to how to divide the oil profits. With regard to the U.S. policy, much will depend on the outcome of the presidential election this November.

THE ULTIMATE BETA TESTER
INTERNET EXPLORER IS DEAD AS MICROSOFT KILLS OFF 25-YEAR-OLD BROWSER


The browser will no longer be supported by the company from 17 August, 2021

Microsoft has finally killed Internet Explorer

The browser will be finished on 17 August, 2021, the company said.

In a blog post, Microsoft explained that the Microsoft Teams web app will no longer support Internet Explorer 11 – the most recent and final iteration of the browser - from November 30, 2020.

The remaining Microsoft 365 apps and services will end support for the browser next year.

Replacing the browser is Microsoft Edge, the computer giant’s new browser which relies on Chromium open-source software, developed by Google for Google Chrome. That gives Edge more features than Internet Explorer.

There is an older version of Edge which does not use Chromium; that version will also be phased out on 9 March 2021.

With many websites and applications still using Internet Explorer, Microsoft is trying to avoid having two active browsers at once.

Instead, Microsoft Edge’s Internet Explorer Legacy mode means that users can stay on one browser – to “seamlessly experience the best of the modern web in one tab while accessing a business-critical legacy IE 11 app in another tab”, the company says.

The closure of Internet Explorer, and Microsoft’s non-Chromium browsers, has been on the cards for years. Internet Explorer 8, 9, and 10 were discontinued in 2016, while Microsoft Edge was introduced one year before, in 2015.

The move towards Chromium for Microsoft’s browser, compared to its previous proprietary browser, has larger ramifications for the future of the open internet. Those concerns have become more pressing in recent months because of, among other things, the fallout between the US government and TikTok.


Chromium is now the basis of Google Chrome, Microsoft Edge, Brave, Vivaldi, Avast Secure Browser, and Opera.

This means that Google has greater influence when it comes to what features are developed, practises accepted, and which usability concerns are deemed vital.


Nonetheless, the new Edge browser includes a range of features that differentiate it from others like Google Chrome.

This includes turning on tracking protection by default, which blocks both advertisements and almost all third-party tracking code.
Famous alien-hunting telescope slashed to pieces in mysterious midnight accident

By Brandon Specktor - Senior Writer 8/14/2020

Arecibo Observatory’s main collecting dish, which is among the world’s largest single-dish radio telescopes, was badly damaged when a cable snapped on Monday, Aug. 10. (Image credit: University of Central Florida)The Arecibo Observatory — a gargantuan telescope in Puerto Rico famous for scouring the cosmos for asteroids and alien life — went quiet this week, following a devastating accident that left the telescope's reflector dish in pieces.

On Monday (Aug. 10) at approximately 2:45 a.m. local time, a metal cable at the facility snapped, slashing through the radar dish and tearing open a 100-foot-long (30 meters) hole, according to a statement from the University of Central Florida, which operates the National Science Foundation-owned facility. The snapped cable also smashed through several other cables and platforms that support the dish, causing debris to rain down on the ground below and making it harder for technicians to access the site.

"We have a team of experts assessing the situation," Francisco Cordova, the director of the observatory, said in the statement. "Our focus is assuring the safety of our staff, protecting the facilities and equipment, and restoring the facility to full operations as soon as possible, so it can continue to assist scientists around the world."

Arecibo began operating in 1963 from the bottom of a natural sinkhole in Puerto Rico. At the time of its completion, Arecibo was the world's largest single-dish telescope, stretching 1,000 feet (305 m) in diameter. While you may not know the telescope by name, you might know it by sight, thanks to the 1997 movie "Contact." That film's protagonist is an astronomer working at Arecibo, who hopes to make first contact with extraterrestrial intelligence. (The observatory's gargantuan reflector dish also stole the show at the end of the 1995 James Bond flick, "GoldenEye.")



Though we're still waiting for that epic first DM from aliens, Arecibo has played a central role in the search for extraterrestrial intelligence (SETI) since the 1970s. In 1974, astronomers used the radio telescope to transmit a binary code toward a dense cluster of stars 25,000 light-years away, hoping the message might get picked up by another technologically-advanced civilization. (It wasn't).

SETI experiments have remained a key part of the observatory's agenda — and so has planetary defense. Arecibo's Planetary Radar Project, part of NASA's Planetary Defense program, is responsible for detecting and studying near-Earth objects, such as asteroids, that could pose a threat to our planet.

That project, along with all other Arecibo projects, has been suspended due to the damage. But Arecibo has bounced back from damage before, including the fallout from earthquakes and Hurricane Maria, and this accident will hopefully be no exception. Still … it would be a lousy time for the aliens to finally return our call.

What does the Pentagon's new UFO task force mean? Experts weigh in.

By Leonard David 8/18/2020

If you're a fan of unidentified flying objects (UFOs) and alien visitation, this is manna from heaven.

Three videos showing U.S. Navy pilots encountering mysterious, fast-moving objects emerged in 2017 and 2018. The videos were made public due to reporting by The New York Times and efforts by To The Stars Academy, a research, development and media center for cutting-edge science and technology.

One of the UAP videos was taken in November 2004, and the other two were shot in January 2015. All were captured by Navy F/A-18 Super Hornet jets with pilots utilizing Forward-Looking Infrared (FLIR) technology, hardware that detects heat and creates images.

The three released UAP videos are called "Gimbal," "GoFast" and "FLIR1" (also known as the "Tic Tac" video).

New task force

Last week, the U.S. Department of Defense (DoD) announced the creation of a task force to analyze and understand the "nature and origins" of UAPs. The Department of the Navy, under the cognizance of the Office of the Under Secretary of Defense for Intelligence and Security, will lead the Unidentified Aerial Phenomena Task Force (UAPTF).

The mission of the UAPTF "is to detect, analyze and catalog UAPs that could potentially pose a threat to U.S. national security," DoD officials said in a brief statement released on Friday (Aug. 14).

But before you set up greeting signs and start tossing out welcome mats for the incoming aliens, a little perspective and context are in order. I asked some UFO specialists what they thought of the newly announced task force.



Cautiously optimistic


"The formation of a task force on UFOs is another welcome development in the recent renewed interest and attention to these reports by government agencies and political actors," said Mark Rodeghier, president and scientific director of the J. Allen Hynek Center for UFO Studies in Chicago.
Without further details, it's impossible to judge how well-positioned the task force will be to seriously investigate reports, Rodeghier added, "but I remain cautiously optimistic for now."

Rodeghier said he understands the need for secrecy. However, "I would hope that as much information as possible is released to the public so we can all be informed on this potentially world-shattering subject," he told Inside Outer Space.

Reasons for the DoD to care

"I have no doubt that military intelligence services around the world have always been interested in ‘UFO reports' — whether or not a real 'unexplainable' phenomenon is behind a few of them."

That's the view of Jim Oberg, a noted space journalist, historian and a debunker of a slew of UFO sightings. He's an admitted "lifelong space nut" and professional rocket scientist whose career includes 20-plus years at NASA's Johnson Space Center in Houston.

There are many non-extraterrestrial reasons why the Defense Department is interested in UFO reports, Oberg said.
First, to identify and ameliorate instrumental "funnies" in new sensory technology, to make sure we don't accidentally misinterpret or overlook future readings.
Second, to determine how detection "funnies" might be deliberately induced by hackers and real enemies, and what we can do to frustrate such efforts.
Third, to deliberately induce anomalous targets into the range of our own new detection/tracking technology, as a way of testing it.
Fourth, to test enemy detection systems with deliberate pokes to identify exploitable weaknesses.
Fifth, to assess which reports from within or near adversary nations are indicators of their classified military testing and operations that we need insight into.
Sixth, to determine which detections (at home or abroad) accidentally reveal highly classified operations of our own that might be revealed to enemy nations that are also looking for such indications, so as to improve our masking, misdirection and stealth.
Seventh, in so far as observations of UFO reports from adversary nations are indicators of leaked observable clues to military capabilities, to do nothing to provoke such regimes from curtailing their own news media coverage of the "pseudo-UFOs." Never announce how such innocent (to them) news items can be exploited.
Eighth, in so far as our own domestic UFO reports may be authentic indicators of classified military activities, to purposefully create camouflage and masking reports to distract, confuse or lull foreign observers and analysts.

"Perceptive observers of the UFO scene over the last two-thirds of a century have noted a telltale feature of the evolution of reports," Oberg said. "Their nature has been changing, keeping uncanny pace with the progress in human observation and detection technologies."

Oberg added that, year by year, the "old UFOs" fade away just before the advent of new technologies that would have unambiguously documented them come online, to be replaced by a new flavor of "anomalies" that precisely match the limits of vision of new technologies.

Not open-ended and ongoing

"I don't think this [task force] is as significant as some people are suggesting," said writer and UFO skeptic Robert Sheaffer. "It's just a response to all the publicity generated by To The Stars leaking the three Navy infrared videos, which the Pentagon later released."

In the military, a task force is something that is put together to deal with a specific situation or problem, Sheaffer said. It is expected to produce a report and recommendations concerning that issue and is disbanded when such work is complete.

"So, this is not something open-ended and ongoing, like Project Blue Book. It does not suggest an ongoing government interest in unidentified objects," Sheaffer observed. Conducted by the United States Air Force, Project Blue Book appraised the UFO situation starting in 1952 and officially closed down in 1970.
Intruding into their sandbox

Military operations areas (MOAs) are clearly designated on aviation maps, and civilian aircraft are generally supposed to avoid them, Sheaffer pointed out.

Most of the recent Pentagon comments about "unidentified objects" mention "range incursions," Sheaffer added — i.e., unknown objects that seem to be entering one of these MOAs.

"So, it seems that the military is worried about unidentified objects that might be intruding into their sandbox. If unidentified objects turn up elsewhere, the military doesn't care," Sheaffer said. "The 'Tic Tac' and 'Gimbal' videos appear to show distant jets, which are probably well outside the MOA, quite far away. The military is investigating out of an abundance of caution, and a sensitivity to criticism."

Temper expectations
Sarah Scoles is author of the recently published book, "They Are Already Here: UFO Culture and Why We See Saucers" (Pegasus Books, 2020).

"First, I'd say that the establishment of a task force to investigate and understand UAP makes sense and could, if done systematically and scientifically and transparently, provide data useful in interpreting pilots' sightings," Scoles told Inside Outer Space.

And it also makes sense, she said, that the Department of Defense — whose job it is, of course, to protect the U.S. from threats — is undertaking this endeavor.

"However, I think those expecting big, exotic conclusions from the task force would do well to temper their expectations," Scoles said. "If you look at what the official announcement actually says, it's not quite as extraordinary as it might seem at first glance."

Boundary-crossing objects

Last week's three-paragraph DoD release, Scoles added, uses language similar to that of other, previous statements about UAPs. For example, a September 2019 statement from Joseph Gradisher, spokesman for the deputy chief of naval operations for information warfare defining "UAP," reads, "The 'Unidentified Aerial Phenomena' terminology is used because it provides the basic descriptor for the sightings/observations of unauthorized/unidentified aircraft/objects entering/operating in the airspace of various military-controlled training ranges."

Scoles said that "UAP" technically could include aircraft or objects that are simply unauthorized, as well as aircraft or objects that cannot be immediately identified. "That means that, if a pilot sees something they cannot explain, but someone else explains it a few hours later, it could still fall under the definition of UAP."
The task force press release uses very similar wording to talk about DoD interest.

"It very specifically states that the DoD is concerned with boundary-crossing by objects that are — right when an observer sees them — unidentified," Scoles said. "It says nothing so specific about objects that remain forever unidentified and mysterious. It certainly says nothing nor implies anything about alien aircraft."

But, like all things UFO, Scoles concluded, "vague and somewhat weaselly wording leaves enough room for people to interpret this latest development very differently."

What would happen to Earth if humans went extinct?

Nature always finds a way.

This city is going green.

Deep within Guatemala's rainforest sits one of the most famous remnants of the Maya civilization: a roughly 2,000-year-old citadel turned to ruins called Tikal. When Alan Weisman hiked through the surrounding region, he discovered something fascinating along the way: "You're walking through this really dense rainforest, and you're walking over hills," said Weisman, author and journalist. "And the archaeologists are explaining to you that what you're really walking over are pyramids and cities that haven't been excavated."

In other words, we know about sites like Tikal because humans have gone to great efforts to dig up and restore their remains. Meanwhile, countless other ruins remain hidden, sealed beneath forest and earth. "It's just amazingly thrilling how fast nature can bury us," Weisman told Live Science.

This scene from the rainforest allows us a glimpse of what our planet could look like, if humans simply stopped existing. Lately, that idea has been especially pertinent, as the global COVID-19 pandemic has kept people inside, and emboldened animals to return to our quieter urban environments — giving us a sense of what life might look like if we retreated further into the background. Weisman, who wrote "The World Without Us" (Thomas Dunne Books, 2007), spent several years interviewing experts and systematically investigating this question: What would happen to our planet — to our cities, to our industries, to nature — if humans disappeared?

Related: What could drive humans to extinction?


A different kind of skyline

There are several developing theories for what could drive humanity to extinction, and it is unlikely that we'd all simply disappear in an instant. Nevertheless, imagining our sudden and complete eradication from the planet — perhaps by an as-yet undiscovered, human-specific virus, Weisman said — is the most powerful way to explore what could occur if humans left the planet.

In Weisman's own research, this question took him firstly into cities, where some of the most dramatic and immediate changes would unfold, thanks to a sudden lack of human maintenance. Without people to run pumps that divert rainfall and rising groundwater, the subways of huge sprawling cities like London and New York would flood within hours of our disappearance, Weisman learned during his research. "[Engineers] have told me that it would take about 36 hours for the subways to flood completely," he said.


Lacking human oversight, glitches in oil refineries and nuclear plants would go unchecked, likely resulting in massive fires, nuclear explosions and devastating nuclear fallout. "There's going to be a gush of radiation if suddenly we disappear. And that's a real wildcard, it's almost impossible to predict what that's going to do," Weisman said. Similarly, in the wake of our demise, we'd leave behind mountains of waste — much of it plastic, which would likely persist for thousands of years, with effects on wildlife that we are only now beginning to understand.
Meanwhile, petroleum waste that spills or seeps into the ground at industrial sites and factories would be broken down and reused by microbes and plants, which would probably take decades. Persistent organic pollutants (POPs) — human-made chemicals such as PCBs that currently can’t be broken down in nature — would take much longer, Weisman says. "Some of these POPs may be around until the end of time on Earth. In time, however, they will be safely buried away." The combined rapid and slow release of all the polluting waste we leave behind would undoubtedly have damaging effects on surrounding habitats and wildlife. (But that doesn't necessarily mean total destruction: We need only look at the rebounding of wildlife at the site of the Chernobyl nuclear disaster to understand that nature can be resilient on short timescales, even under such extremes.)

While that polluting legacy unfolds, water running underground in cities would corrode the metal structures that hold up the streets above subterranean transport systems, and whole avenues would collapse, transformed suddenly into mid-city rivers, Weisman explained. Over successive winters, without humans to do regular de-icing, pavements would crack, providing new niches for seeds to take root — carried on the wind and excreted by overflying birds — and develop into trees that continue the gradual dismemberment of pavements and roads. The same would happen to bridges, without humans there to weed out rogue saplings taking root between the steel rivets: coupled with general degradation, this could dismantle these structures within a few hundred years.

Related: Are trees vegetarian?

With all this fresh new habitat opening up, nature would stoically march in, pasting over the formerly concrete jungle with grasslands, shrubbery and dense stands of trees. That would cause the accumulation of dry organic material, such as leaves and twigs — providing the perfect fodder for fires sparked by lightning, which would go roaring through the maze of buildings and streets, potentially razing whole parts of cities to the ground. "Fires are going to create a lot of charred material that will fall to the street, which is going to be terrific for nurturing biological life. The streets will convert to little grasslands and forests growing up within 500 years," as Weisman tells it.

Over hundreds of years, as buildings are subjected to sustained damage from erosion and fire, they would degrade, he said. The first to topple would be modern glass and metal structures that would shatter and rust. But tellingly, "buildings that will last the longest are the ones made out of the Earth itself" — like stone structures, Wesiman added. Even those would become a softened version of their former selves: eventually the defined, iconic skylines we know so well today would be no more.


Where the wild things are

Looking beyond the city limits to the great swathes of farmland that currently cover half of Earth's habitable land, there would be a swift recovery of insects, as the application of pesticides and other chemicals ceases with humanity's demise. "That's going to start a real cascade of events," Weisman said. "Once the insects are doing better, then the plants are going to do much better, then the birds." Surrounding habitats — plant communities, soils, waterways and oceans — will recover, free from the far-reaching influence that chemicals have on ecosystems today. That, in turn, will encourage more wildlife to move in and take up residence.
This transition will precipitate an increase in biodiversity on a global scale. Researchers who have modeled the diversity of megafauna — the likes of lions, elephants, tigers, rhinoceroses and bears — across the planet have revealed that the world used to be exceptionally rich in these species. But that changed when humans began to spread across the planet, hunting these animals and invading their habitats. As humans migrated out of Africa and Eurasia to other parts of the globe, "we see a consistent increase in extinction rates following the arrival of humans," explained Søren Faurby, a lecturer in macroecology and macroevolution at the University of Gothenburg in Sweden. "In Australia, there is an increase in extinction near 60,000 years ago. In North and South America, an increase is seen [about] 15,000 years ago, and in Madagascar and the Caribbean islands a drastic increase is seen a few thousand years ago."


Related: Why haven't all primates evolved into humans?


Without humans spreading to the far corners of the Earth and driving down megafauna populations, the entire planet could have been as diverse in these species as the famed Serengeti in East Africa is today, Faurby told Live Science. "Effectively, there used to be large animals everywhere, and there would be large animals everywhere around the globe without human involvement." His research has revealed that without humanity's heavy species impact, the central United States, and parts of South America, would be the most megafauna-rich places on Earth today. Animals like elephants would be a common sight in the Mediterranean Islands. There would even be rhinoceroses across most of northern Europe.


Without humans, could Earth reclaim that diversity? Even if we did suddenly disappear from the picture, it would still take millions of years for the planet to recover from those past extinctions, Faurby and his colleagues have calculated. They investigated what it would take to return to a baseline level of species richness and a distribution of large-bodied animals across the planet that mirrors what we had before modern humans fanned out across the globe. They estimate it would take "somewhere between 3 and up to 7 million or more years to get back to the pre-extinction baseline," explained Jens-Christian Svenning, a professor of macroecology and biogeography at Aarhus University in Denmark, and a colleague of Faurby's who has worked on the same body of research.

Basically, "if there weren't human impacts, the whole world would be one big wilderness," Svenning told Live Science.
Nature finds a way


The planet might eventually become lusher and more diverse — but we can't dismiss the effects of climate change, arguably humanity's most indelible impact on the planet. Weisman notes the inherent uncertainty in making useful predictions about what will unfold. For instance, if there are explosions at industrial plants, or oil or gas wellheads that continue to burn long after we're all gone, huge amounts of heat-trapping carbon dioxide would continue to be discharged into the atmosphere, he explained.


Carbon dioxide doesn't stay suspended in the atmosphere forever: Our oceans play an essential role in absorbing vast amounts of carbon dioxide from the air. But there are still limits to how much of it the ocean can take up without its own waters acidifying to unhealthy levels — potentially to the detriment of thousands of marine species. There's also a cap on how much the sea can physically absorb, meaning it isn't simply the bottomless carbon sink it's often thought to be.


Related: What are the ingredients of life?


As it stands, current levels of CO2 in our atmosphere will already take thousands of years to be fully removed from the atmosphere. (Based on the research he did for his own book, Weisman found it could take upwards of 100,000 years.) And if the sea reaches its cap and more greenhouse gases stay suspended up in the atmosphere, the resulting continuous warming will lead to further melting of the polar ice caps, and the release of even more greenhouse gases from softening permafrost. This will cycle into an ongoing, climate-altering, feedback loop. All this means that we can confidently assume that climate change's impacts will last long after we leave.


But to this, Weisman offered a word of hope. During the Jurassic period, he said, there was five times as much carbon dioxide in the atmosphere as there is today, which led to a dramatic increase in ocean acidity. Evidently, however, there must have been marine species that coped with these extremes, and went on to evolve and be part of the planet we know today. Which is to say that ultimately, despite climate extremes and the immense losses they can incur, "nature always finds a way," Weisman said.

There might one day be a world without humans, but that won't stop the rest of the planet from soldiering on.

Moving forward

Is there any point in us pondering what our planet will look like, without us here? Well, on the one hand, we might simply take comfort in the knowledge that, free of people, our planet would ultimately be fine, as Weisman said. In fact, it would ultimately thrive.

But taking a glimpse at this imagined future might also prompt us to be more mindful of our actions, in a bid to preserve our own spot on the planet, too. Weisman sees an inherent value to visualizing a world without us, which is why he decided to write his book in the first place. He explained that when he started out, he was conscious that many people avoid environmental stories because it makes them feel bad about the damage that humans are doing to the planet, and how in turn, that's hastening our own demise. "I found out a way to get rid of the fear factor was just to kill [humans] off first," he said, with humor.

With that distraction gone, he found, he could focus people's attention on the planet, and the real point he wanted to make: "I wanted people to see how beautifully nature could come back, and even heal a lot of the scars that we've placed on this planet. Then to think, is there possibly a way to add ourselves back into this picture of a restored Earth?"

This palm-sized elephant relative was just sighted for the first time in 50 years

It's related to an elephant, has a long nose, a fur tuft on its tail and big, spectacled eyes.

A teensy animal, with a long nose, a fur tuft on its tail and big, spectacled eyes hadn't been seen in nearly half a century. That is, until a whiff of peanut butter lured the wee mouse-sized mammal out from the rocky, rugged lands of Djibouti in the Horn of Africa.

The recently "rediscovered" mammal, called a Somali sengi (Elephantulus revoilii), is a species of elephant shrew. While elephant shrews are related to elephants, aardvarks and manatees — they're not elephants and they're not shrews.

The Somali sengi has not been seen since 1973. Everything known about the obscure mini mammal came from 39 individual specimens that were collected decades and centuries ago and that are now stored in museums, according to a statement from Global Wildlife Conservation.

In 2019, a group of scientists from the U.S. and Djibouti set out to look for the species after receiving tips that the creatures could be hiding in Djibouti, although the animals had only previously been found in Somalia, according to the statement.

"For us living in Djibouti, and by extension the Horn of Africa, we never considered the sengis to be 'lost,' but this new research does bring the Somali sengi back into the scientific community, which we value," co-author Houssein Rayaleh, a research ecologist and conservationist with the nonprofit organization Association Djibouti Nature, said in the statement. Rayaleh had seen the creature before — and locals had too, correctly identifying it in photos during interviews with the scientists, according to the statement.

Using information from interviews, analysis of dung piles at candidate sites and assessments of terrain and sheltering potential, the researchers set up 1,259 traps at 12 different locations across the rocky terrain. They lured the animals to the traps by setting out peanut butter, oatmeal and yeast. They caught one of the elusive mammals in the first trap they set.

In total, they found 12 Somali sengis, which they could distinguish from a similar species by the tuft of fur on their tails, according to the statement. "For Djibouti, this is an important story that highlights the great biodiversity of the country and the region and shows that there are opportunities for new science and research here," Rayaleh said.

They found all of sengis by rocky outcrops and relatively sparse vegetation, areas that are typically inhospitable to human activities, meaning the tiny creatures are not likely to experience habitat destruction, according to the statement. Because they found comparable numbers to other sengi taxa and because they now know that the creatures live beyond just Somalia, the authors recommended that the IUCN Red List of Threatened Species change the Somali sengi's current "data deficient" status to "least concern," according to the statement.

"Usually when we rediscover lost species, we find just one or two individuals and have to act quickly to try to prevent their imminent extinction," Robin Moore, one of GWC's Search for Lost Species program leads, said in the statement. "This is a welcome and wonderful rediscovery during a time of turmoil for our planet, and one that fills us with renewed hope for the remaining small mammal species on our most wanted list." (GWC crafted a list of 25 of the most wanted "lost" species.)

The findings were published today (Aug. 18) in the journal PeerJ.

'Dent' or anomaly is small but getting bigger, scientists warn

Andrew Griffin

Nasa is monitoring a "small but evolving dent" in the Earth's magnetic field that could cause major problems for satellites and spacecraft.

The Earth's magnetic field wraps around our planet, bouncing away charged particles that come to us from the Sun. But there is an unexplained gap in it, where the magnetic field is weak, hovering over South America and the southern Atlantic Ocean.

What's more, the region is spreading and continuing to weaken, leading to fears that the problem could get worse.

Researchers refer to the gap as the "South Atlantic Anomaly, or SAA", and fear that it could cause significant problems for equipment that is used on Earth. Within the anomaly, particles are able to get closer to the surface than usual, meaning that satellites and computers that pass through it could be hit by problems.
That has led Nasa to devote resources to tracking the dent, in an attempt to better understand where it is and what could be causing it.

At the moment, there is no obvious consequence of the SAA for anyone living on Earth. But detailed observations have suggested that it is getting more extreme and that it is expanding to the west, as well as splitting so that there are two points at which the anomaly is least strong.

The Earth's magnetic field – and the changes it undergoes – are happening beneath our feet. Underneath the Earth, in its outer core, metals are churning that create electric currents that then go on to produce the important magnetic field.

Over time, those conditions within the core change, and so does the magnetic field. It is those changes that lead to phenomena such as the SAA.

But the greatest concern about the magnetic fields for the time being is it effects on equipment away from Earth's surface. Ordinarily, the magnetic field keeps the satellites that are around the Earth safe – including inhabited ones like the International Space Station – but the changes mean they lack the protection as they fly through the area covered by the SAA.

At the moment, operators are forced to shut down specific components as they pass through the area. That is one of the reasons that tracking the SAA is important to Nasa, since it needs to know exactly where it is so that those changes can be made most accurately.

With better data in the future, Nasa hopes to be able to more accurately predict how the SAA could be changing and therefore what danger it might pose to satellites and the instruments on them. Future missions will better inform those models, Nasa says, and can also be used to better understand the processes in the Earth that are leading to the changes.
‘Oumuamua remains a mystery: study nixes molecular hydrogen ice theory
Brittany A. Roston - Aug 18, 2020, 2:14 pm CDT0
The interstellar space rock dubbed ‘Oumuamua remains a mystery, according to a new study from Harvard University, which found that contrary to past findings, this cigar-shaped object is in fact not made from molecular hydrogen ice. The findings were recently published in The Astrophysical Journal Letters, detailing the reasons the molecular hydrogen ice proposal doesn’t fit what scientists know about such objects.

‘Oumuamua was spied in late 2017 and is the first (known) interstellar object to travel into our Solar System. The celestial object is moving incredibly fast, is shaped somewhat like a cigar, and it displays unique properties. What was first thought to be an asteroid, ‘Oumuamua was soon found to behave more like a comet, yet it displays certain properties not associated with either type of object.

Many details about this space object were published in the following months, including that it measures up to 400 meters in length and may be around 10 times longer than it is wide. This would be the most extreme aspect ratio of all known comets and asteroids found in our Solar System, according to NASA. The unusual nature of the object spurred fun speculation that perhaps ‘Oumuamua is an alien probe deliberately sent into our Solar System to gather data.

That is, of course, quite unlikely, but we still don’t have all the answers about ‘Oumuamua. In their new paper, researchers with the Harvard & Smithsonian’s Center for Astrophysics, as well as the Korea Astronomy and Space Science Institute, explain why the object couldn’t be made from molecular hydrogen ice as proposed in a paper published earlier this year.

The latest study’s lead author Dr. Thiem Hoang explained:

The proposal by Seligman and Laughlin appeared promising because it might explain the extreme elongated shape of ‘Oumuamua as well as the non-gravitational acceleration. However, their theory is based on an assumption that H2 ice could form in dense molecular clouds. If this is true, H2 ice objects could be abundant in the universe, and thus would have far-reaching implications. H2 ice was also proposed to explain dark matter, a mystery of modern astrophysics. We wanted to not only test the assumptions in the theory but also the dark matter proposition.

When ‘Oumuamua was detected in late 2017, it was moving at an incredibly fast speed of 196,000 miles per hour. The researchers express skepticism that a hydrogen iceberg could survive an intense high-speed journey across this distance for the duration of hundreds of millions of years without evaporating rapidly — and whether such an object could form in molecular clouds at all, according to study co-author Dr. Avi Loeb.

The Harvard Professor of Science went on to state that:

The most likely place to make hydrogen icebergs is in the densest environments of the interstellar medium. These are giant molecular clouds [GMCs] … Thermal sublimation by collisional heating in GMCs could destroy molecular hydrogen icebergs of ‘Oumuamua-size before their escape into the interstellar medium.

Of course, it’s only a matter of time before scientists figure out what this object is, particularly if the upcoming Vera C. Rubin Observatory scheduled to go live next year manages to find other similar objects, Loeb says.

Like the mythical half-human, half-horse creatures, centaurs in the solar system are hybrids between asteroids and comets. Now, astronomers have caught one morphing from one type of space rock to the other, potentially giving scientists an unprecedented chance to watch a comet form in real time in the decades to come.

“We have an opportunity here to see the birth of a comet as it starts to become active,” says planetary scientist Kat Volk of the University of Arizona in Tucson.

The object, called P/2019 LD2, was discovered by the ATLAS telescope in Hawaii in May. Its orbit suggests that it’s a centaur, a class of rocky and icy objects with unstable orbits. Because of that mixed composition and potential to move around the solar system, astronomers have long suspected that centaurs are a missing link between small icy bodies in the Kuiper Belt beyond Neptune and comets that regularly visit the inner solar system (SN: 11/19/94).

These “short-period” comets, which are thought to originate from icy objects in the Kuiper Belt, orbit the sun once a decade or so, and make repeat appearances in Earth’s skies. (Long-period comets, like Halley’s Comet, which visits the inner solar system once a century, probably originate even farther from the sun, in the Oort cloud (SN: 10/25/13).)

All previously found short-period comets were spotted only after they had transitioned into comets (SN: 8/6/14). But LD2 just came in from the Kuiper Belt recently and will become a comet in as little as 43 years, Volk and colleagues report August 10 at arXiv.org.

“It’s weird to think that this object should be becoming a comet when I’m retiring,” Volk says.

In 2019, she and colleagues showed that there’s a region of space just beyond Jupiter that they call the “Gateway”. In this area, small planetary objects hang out while warming up and transitioning from outer solar system ice balls to inner solar system comets with their long tails. It’s like a comet incubator, says planetary scientist Gal Sarid of the SETI Institute, who is based in Rockville, Md.

After hearing about LD2, Volk, Sarid and their colleagues simulated thousands of possible trajectories to see where the object had been and where it is going. LD2’s orbit probably took it near Saturn around 1850, and it entered its current orbit past Jupiter after a close encounter with the gas giant in 2017, the team found. The object will leave its present orbit and move in toward the sun in 2063, where heat from the sun will probably sublimate LD2’s volatile elements, giving it a bright cometary tail, the researchers say.

“This will be the first ever comet that we know its history, because we’ve seen it before being a comet,” Sarid says.

The fact that LD2 is fairly new to the inner reaches of the solar system suggests that it’s made of relatively pristine material that has been in the back of the solar system’s freezer for billions of years, unaltered by heat from the sun. That would make it a time capsule of the early solar system. Studying its composition could help planetary scientists learn what the first planets were made of.

The orbital analysis looks “very reasonable,” says Henry Hsieh, a planetary astronomer with the Planetary Science Institute who is based in Honolulu and was not involved in the study. But studying just one transition object is not enough to open the solar system time capsule.

“What we really need to do is study many of these,” he says. “Study this one first, and then study more of them, and figure out whether this object is an outlier or whether we see a consistent picture.” Future sky surveys, like the ones planned using the future Vera Rubin Observatory (SN: 1/10/20), should discover more balls of ice shifting into comets.

Sarid and colleagues think LD2 could be a good target for a spacecraft to visit. NASA has considered sending spacecraft to centaurs, although no missions have been selected for development yet. But considering that LD2 will become a comet in just a few decades, scientists don’t have much time to plan, build and launch a mission to visit it. “The windows are closing,” Sarid says. “We really need to be doing this now.”

Inside the Grueling Battle to Declassify Homosexuality as a Mental Illness
HISTORY LESSON

The documentary ‘CURED’ chronicles the fight to remove homosexuality from the DSM. But it overlooks the contributions of Black and brown voices—and censors some activists’ racism.

Any ‘Gay and Lesbian History’ college course will dive into closeted white suburban gay male representations. In fact, this group of men, sneaking around in mid-century America, have received a fair bit of Hollywood attention in recent years. There was fashion designer Tom Ford’s adaptation of Christopher Isherwood’s haunting novel A Single Man, Benedict Cumberbatch’s Oscar vehicle The Imitation Game, and Luca Guadagnino’s take on André Aciman’s Call Me by Your Name. Todd Haynes’s excellent Far From Heaven refocused the lens from a cheating closeted suburban husband to the wife’s own relationship with a Black man who works as her gardener, while Ang Lee’s Brokeback Mountain and Francis Lee’s God’s Own Country look at white male closeted culture in the context of working-class masculinity.

Patrick Sammon and Bennett Singer’s new documentary CURED looks at the white suburban gay through the lens of activism. The film chronicles the drive by lesbian and gay activists, especially Barbara Gittings and Frank Kameny, to get homosexuality removed from the Diagnostic and Statistical Manual of Mental Disorders (DSM). The story itself is a vital one to know, because it marks one of the first major drives toward a rights-oriented LGBTQ+ movement. Notably, those fighting to have homosexuality removed from the DSM were mostly middle and upper class cis white gays and lesbians—people with college educations, good jobs, perhaps even nuclear families who were fighting to live openly as gay while taking part in polite society.

CURED features one Black lesbian from a working-class background, Reverend Magora Kennedy, who married to avoid being sent to Utica State Hospital where she would’ve received electroshock therapy as treatment for her homosexuality. After having five children, she left her husband and began to live openly as a lesbian. She attended talk shows and panels with Gittings, the spokeswoman of the movement, and several other white lesbians. She also was present at the Stonewall Riots, and the film provides a brief glance toward those events, which were the first major spark of the gay liberation movement headed up by Black and brown trans women as well as sex workers, street kids, disabled people, and the kind of queers who were not seeking assimilation into the dominant social order, but rather the freedom to live as themselves without being harmed by the state. I don’t believe there is a simple hierarchy between these sets of desires, but they do not smoothly intersect, and have continually been at odds. For example, Larry Kramer’s bravely flagrant ACT UP movement during the HIV/AIDs epidemic spurned the status quo while the more recent gay marriage movement prioritized inclusion into an enshrined social system over, perhaps, the kind of reimagining of family that could protect homeless LGBTQ+ youth.

CURED does not differentiate gay rights from gay liberation or provide a robust context for how homophobia functioned at the time in a country also ridden with racism, classism, and ableism. And this move—to vacuum-seal the fight to remove homosexuality from the DSM—unfortunately does a disservice to the film’s message because it denies the activists involved the opportunity to make the case for why assimilation was so collectively, and not individually, crucial to them and others at the time.


Several of the psychiatrists in the American Psychiatric Association (APA) that presided over the DSM at the time were gay. In fact, there was a secret society of gay psychiatrists within the APA, some of whom were in leadership. Of course, the extreme majority of the APA were white men, and in CURED, there are merely glimpses of anyone else within the institution. As you can imagine, homophobia was not the only prejudice entrenched within psychiatry as an institution in the U.S.—blackness, specifically, was pathologized, as was being a woman; addiction was seen as a moral failing, and genuinely mentally-ill patients were often looked down upon by the doctors treating them.

The closeted gay doctor John E. Fryer, who famously testified to the APA about homosexuality’s inclusion in the DSM while wearing a Halloween-appropriate mask disguise, wrote in his journal afterwards, “...I have identified with a force which is akin to my selfhood. I am not Black, I am not alcoholic, I am not really addicted. I am homosexual...” (emphasis mine). That second sentence is omitted from the reading Fryer’s still-living friend performs for the camera, and in an image of the journal, it is grayed out. I had to pause the documentary and take a screenshot in order to make sense of what was glossed over.

Why was it so important for Fryer to say, to himself, in his diary, that he was not Black? And in the same space of thought in which he declared he was not an alcoholic or otherwise addicted?

Why was it so important for Fryer to say, to himself, in his diary, that he was not Black? And in the same space of thought in which he declared he was not an alcoholic or otherwise addicted?


We know that, at that time (and in many ways still today), major institutions believed blackness itself was a form of deviance, as was alcoholism and drug use. It seems that Fryer was trying to say that, unlike Black people or alcoholics or drug users, I am not deviant—I am merely a gay man. And perhaps Sammon and Singer thought that examining this prejudice would be inconvenient to the triumphant tone of the film and uncomfortable for the interviewees to address. But this bigotry, even within the gay-rights movement, is not a distraction but a major point. A key argument against focusing on acquiring rights within a deeply compromised system—rather than working to liberate each other from it—is that those who receive the full benefits of those rights will be the ones already positioned to dominate once those rights are acquired; the good fortune will not simply trickle down. What good is it to a Black gay man if his psychiatrist doesn’t see his homosexuality as deviant but believes in race science? What good is it to a lesbian seeking treatment for bipolar disorder if the classification in the DSM is based exclusively on cis male subjects?

Removing homosexuality from the DSM has certainly made it more possible for gay people to stay out of mental institutions on the basis of their sexuality and paved the way to the anti-discrimination laws that make it difficult for employers to prejudicially fire gay and trans employees with impunity. But this reform movement was not a revolution as CURED implies—nothing fundamental about the social and political order that makes such discrimination so life-threatening has changed. Right now, the Trump administration is angling to wipe away many of these rights in the name of “religious freedom”—if they manage it alongside an election win, a more radical approach would likely be the only way forward, at least in this lifetime. Perhaps, then, in the accounting of things, Stonewall—and the Black and brown activists who helped lead the charge—will not serve as a mere footnote.
