Santiago: Chile's economic activity has dropped 3.3 per cent in November, led by a slump in mining activity, the central bank said on Thursday, local time, and officials predicted low growth for the coming year as the country reels from anti-government unrest.

Protests have rocked Chile, the world's top copper producer, for two months, leaving 26 dead and causing billions in losses for private businesses and public infrastructure. Demonstrations and sometimes violent riots and looting prompted the central bank in December to slash forecasts for growth, investment and demand through 2020.

The IMACEC economic activity index reported on Thursday encompasses about 90 per cent of the economy that gross domestic product covers.

Finance Minister Ignacio Briones said the bad news was largely expected, but bode poorly for the coming months.

"The October and November IMACECs are among the worst since the sub-prime crisis," Briones said. "In 2020 we expect to have a year of low growth."

Mining activity measured in GDP terms plunged 5.1 per cent in November, the bank said, dragging overall growth downwards and marking an early sign that the protests may have had a knock-on effect on the main economic driver.

Chile's vast copper mines - the country produces nearly a third of the world's copper - had largely maintained production and operated normally through early November at the height of the unrest, though some mining companies had warned that protests, strikes and road blockades were taking a toll.

Non-mining activity also fell 3.1 per cent, the central bank said, led by a fall in both commerce and the services. The bank highlighted sharp declines in transportation and tourism.

Much of the capital Santiago, with a population of 6 million, was shut for a period near the end of October as riots and looting closed streets, central squares and many small businesses, hotels and restaurants.

Despite dire predictions, unemployment through November fell slightly, the government said earlier this week.

Analysts and economists have said since that an increase in job losses would likely be felt in subsequent months, as unemployment lags behind falling economic growth.

Chile's finance minister said in mid-November that as many as 300,000 jobs could be lost as a result of the protests.


He told reporters he hesitated to make further predictions, but said he was "worried" about the impact of slumping economic growth on unemployment.

"It's not yet been reflected in the data...and hopefully, it won't be," he said. "But we have to pay extremely close attention."

But Bloomberg reported the country's foreign reputation for sound fiscal management has survived the protests largely intact and the government now intends to cash in on that credibility.

As Andres Perez, head of international finance at Chile's Finance Ministry, visited institutional investors in Asia and the US in December to explain the social crisis and remind them of Chile's financial strengths, he was struck by the high expectations the country has created.

There's a consensus that Chile's fiscal and monetary response has been "effective, fast and decisive in terms of its size," Perez said in an interview in Santiago. "Then again, they say that this is what they expect of Chile."

Plant-based burgers will make men grow boobs, Livestock News reports
There's still no evidence to support this claim.

Amid the growing popularity of the Impossible Burger, Beyond Meat products, and other plant-based meat alternatives, the meat industry has declared war.
FURTHER READING Plant-based burgers are “ultra-processed” like dog food, meat-backed ads say 
Despite coming out with their own competing alternative and plant-based products, various meat industry-backed efforts have claimed that the vegetarian-friendly foods are harmful and “ultra-processed.” They’ve also compared them to dog food.

Now, there’s a new claim: that they’ll make men grow breasts.

As first noted by The Washington Post, an article labeled as “news” in the trade publication Tri-State Livestock News claims that eating Burger King’s Impossible Whopper—a new faux-beef menu item—could cause men to grow breasts.

Author James Stangle, a doctor of veterinary medicine in South Dakota, orders up some sizzling math, hold the evidence. He writes:

The impossible whopper has 44mg of estrogen and the whopper has 2.5ng of estrogen. Now let me refresh your metric system. There are 1 million nanograms (ng) in one milligram (mg). That means an impossible whopper has 18 million times as much estrogen as a regular whopper. Just six glasses of soy milk per day has enough estrogen to grow boobs on a male. That’s the equivalent of eating four impossible whoppers per day. You would have to eat 880 pounds of beef from an implanted steer to equal the amount of estrogen in one birth control pill.

The Post also notes that conservative news outlets, such as National File and MichaelSavage.com, have parroted the claims. “In short, the Impossible Burger is a genetically modified organism filled with calorie-dense oils that can make a man grow breasts if eaten in sufficient quantity,” Tom Pappert, editor in chief of the National File, concluded.
Plant-based bull

The claim that soy-based foods, like the Impossible Whopper, will “feminize” men is a tired one that has been around for years—and still lacks evidence to back it up.

It’s based on the fact that soy contains a high concentration of isoflavones. These are plant-derived chemicals that can act like estrogen in some tissues in mammals but are much weaker than the real sex hormone.
FURTHER READING Fake-meat fans have beef with Big Meat for trying to cut into plant-based marketSoy consumption and its isoflavones have been studied extensively. There have been thousands of studies on its hypothetical benefits and harms to human health—from possibly protecting against certain types of cancers, possibly preventing heart disease, and possibly easing the symptoms of menopause, as well as possibly contributing to poor cognition in older age, and possibly reducing thyroid hormone levels. For general reviews of the findings, click here and here.

Then there are the studies that have looked into whether isoflavones can feminize men and infants and interfere with fertility and development. The general concern goes back decades and has been bolstered by the occasional case report and animal study, which have questionable applicability to human health overall.

In particular, the fear of men growing breasts from soy consumption was highlighted in a 2008 case report in which a 60-year-old man developed benign swelling of male breast tissue and elevated estrogen levels. Doctors reported that the man consumed a whopping three quarts of soymilk a day. That would provide around eight times the intake of isoflavones that have been recorded in older men in Japan and Shanghai who eat soy-heavy diets.

One nutrition researcher noted of the case report that such excessive intake of pretty much any nutritious food could result in untoward effects. For instance, if the soymilk had been fortified with calcium, it would have resulted in an overdose that can cause hypercalcemia.

Overall, analyses of numerous studies have found no evidence that isoflavone consumption in normal ranges affects male hormone levels or sperm and semen quality. Likewise, there is no conclusive evidence that soy-based infant formula has adverse effects, either. The American Academy of Pediatrics has concluded that “soy protein-based formulas are a safe and nutritionally equivalent alternative to cow milk-based formula for term infants whose nutritional needs are not met from breast milk.”

While nutrition researchers say long-term human studies could help provide more concrete conclusions, for now, there's no reason to think eating an Impossible Whopper will increase anyone's cup size.

Ecologists at the University of Sydney told News.com.au that an estimated 480 million mammals, birds, and reptiles, have died in the bushfires sweeping Australia.Eight thousand of the animals deaths are believed to be koalas, The Independent reported. Federal environment minister Sussan Ley told ABC Radio on Friday that up to 30% of koalas in New South Wales have been killed by the fires.As of Thursday morning, more than 130 fires were burning in New South Wales and Victoria. The fires have razed more than 9.9 million acres across five states.At least 18 people have died as a result of the bushfires. Some 1,400 homes have been destroyed.

Nearly half a billion animals are believed to be dead in the bushfires still spreading across Australia.

Ecologists at the University of Sydney told News.com.au that an estimated 480 million mammals, birds, and reptiles have died in the bushfires, which have been burning across Australia since September. Eight thousand of the animals deaths are believed to be koalas, The Independent reported.

As of Thursday morning, more than 130 fires were burning in New South Wales and Victoria. The fires have razed more than 9.9 million acres across five states. At least 18 people have died as a result of the bushfires. Some 1,400 homes have been destroyed.

Animals living in the regions include koalas, kangaroos, wallabies, possums, wombats, and echidnas.

Tracy Burgess, a volunteer at Wildlife Information, Rescue and Education Services, told Reuters that rescuers aren't receiving as many animal patients as expected, which is cause for concern.

"Our concern is that they don't come into care because they're not there anymore, basically," she said.

Rescuers across the country have shared videos and photos of burned and dehydrated animals being cared for and fed by local residents.

Federal environment minister Sussan Ley told ABC Radio on Friday that up to 30% of koalas in New South Wales have been killed by the fires.

Nature Conservation Council ecologist Mark Graham told parliament in December that koalas can't move fast enough to escape the fires. Koalas also eat leaves from eucalyptus trees, which are highly flammable.

"The fires have burned so hot and so fast that there has been significant mortality of animals in the trees, but there is such a big area now that is still on fire and still burning that we will probably never find the bodies," he said, according to The Independent.

Food and fuel are running out in remote areas of southeastern Australia as the fires rage on. Weather conditions are expected to worsen through the week.

Scientists believe meteors may be striking Earth more frequently than thought

By Ben Mitchell, PA,
PA Media: Science•January 2, 2020

Scientists believe that meteors may be striking the Earth more often than previously thought after they found one of the world’s largest craters is 180,000 years younger than earlier estimates.

Dr Tim Barrows, from the University of Portsmouth, has used two dating techniques to establish that Wolfe Creek Crater in northern Western Australia is 120,000 years old – not the 300,000 years it was previously aged at.

He explained that the crater was most likely to have been created by a meteor about 15 metres in diameter and weighing 14,000 tonnes hitting the Earth.

For the study published in the journal Meteoritics & Planetary Science, the researchers collected samples from around the crater and used exposure dating which estimates the length of time a rock has been exposed at the Earth’s surface to cosmic radiation.

And they were also able to determine the age of sand buried after the impact through optically stimulated luminescence – a dating technique which measures how long ago sediment was last exposed to sunlight.

Dr Barrows, a professor of environmental change, said: “The crater is located in a fortuitous situation where we can use two different techniques to determine its age.”

Wolfe Creek Crater is one of seven sets of impact craters in Australia dating to within the last 120,000 years. From this, the researchers were able to calculate how often these crater-producing events occur.

Dr Barrows explained that the dating exercise suggested that meteors could be striking the planet more frequently than previously calculated.

He said: “Although the rate is only one large meteor hitting Australia every 17,000 years, it isn’t that simple. The craters are only found in the arid parts of Australia.

“Elsewhere, the craters are destroyed by geomorphic activity like river migration or slope processes in the mountains.

“Since Australia has an excellent preservation record with dated craters within the arid zone, we can estimate a rate for the whole Earth.

“Taking into account that arid Australia is only about 1% of the surface, the rate increases to one hitting the Earth every 180 years or so.

“There have been two big objects hitting the atmosphere in the last century – Tunguska in 1908 and Chelyabinsk in 2013.

“This is a minimum estimate because some smaller impacts were probably covered by sand during the last ice age.

“The number of large objects in the atmosphere is probably 20 times this number because stony meteorites are far more common but not as many survive the fiery journey through the atmosphere or effectively make craters.

“Our results give us a better idea of how frequent these events are.”

Female warriors' tomb suggests basis for Amazons of Greek mythology


USA TODAY•January 2, 2020

The Amazons, a mythical race of female warriors that inspired fictional heroes such as Wonder Woman and Xena the Warrior Princess, may have been more than ancient Greek lore.

The Institute of Archaeology at the Russian Academy of Sciences announced the discovery of a tomb where four women were buried alongside a slew of battle weapons about 2,500 years ago. The findings were published by the Akson Russian Science Communication Association last Wednesday.

The Scythian women represented three generations of female warriors. The eldest was buried with a ceremonial headdress consistent with Amazon myths.

Valerii Guliaev led the archaeological expedition at a burial ground in the Russian village of Devitsa. She said in a news release that other Amazons have been discovered, but this is the first time the women ranged so widely in age.

The youngest was a girl researchers estimated was 12 or 13. Two women were 20 to 29 and 25 to 35 years old. The eldest woman was 45 to 50 years old. The average life expectancy for a woman during that time was 30 to 35 years.

The cemetery consisted of 19 mounds, which researchers said were broken into by robbers during ancient times. Archaeologists found 30 iron arrowheads, an iron hook, fragments of horse harness, iron knives and jewelry that was 65% to 70% gold.

The burial ground was found in 2000, and work for the expedition has been ongoing since 2010. Since then, researchers have discovered about 11 burials of young armed women.

TIME TWISTER

Astrophysicist Says He Knows How to Build a Time Machine

But his peers are far from convinced that it'll work.

Astrophysicist Ron Mallett believes he’s found a way to travel back in time — theoretically.
The tenured University of Connecticut physics professor recently told CNN that he’s written a scientific equation that could serve as the foundation for an actual time machine. He’s even built a prototype device to illustrate a key component of his theory — though Mallett’s peers remain unconvinced that his time machine will ever come to fruition.
To understand Mallett’s machine, you need to know the basics of Albert Einstein’s theory of special relativity, which states that time accelerates or decelerates depending on the speed at which an object is moving.
Based on that theory, if a person was in a spaceship traveling near the speed of light, time would pass more slowly for them than it would for someone who remained on Earth. Essentially, the astronaut could zip around space for less than a week, and when they returned to Earth, 10 years would have passed for the people they’d left behind, making it seem to the astronaut like they’d time traveled to the future.
But while most physicists accept that skipping forward in time in that way is probably possible, time traveling to the past is a whole other issue — and one Mallett thinks he could solve using lasers.
As the astrophysicist explained to CNN, his idea for a time machine hinges upon another Einstein theory, the general theory of relativity. According to that theory, massive objects bend space-time — an effect we perceive as gravity — and the stronger gravity is, the slower time passes.
“If you can bend space, there’s a possibility of you twisting space,” Mallett told CNN. “In Einstein’s theory, what we call space also involves time — that’s why it’s called space time, whatever it is you do to space also happens to time.”
He believes it’s theoretically possible to twist time into a loop that would allow for time travel into the past. He’s even built a prototype showing how lasers might help achieve this goal.
“By studying the type of gravitational field that was produced by a ring laser,” Mallett told CNN, “this could lead to a new way of looking at the possibility of a time machine based on a circulating beam of light.”
As optimistic as Mallet might be about his work, though, his peers are skeptical that he’s on the path to a working time machine.
“I don’t think [his work is] necessarily going to be fruitful,” astrophysicist Paul Sutter told CNN, “because I do think that there are deep flaws in his mathematics and his theory, and so a practical device seems unattainable.”
Even Mallet concedes that his idea is wholly theoretical at this point. And that even if his time machine does work, he admits, it would have a severe limitation that would prevent anyone from, say, traveling back in time to kill baby Adolf Hitler.
“You can send information back,” he told CNN, “but you can only send it back to the point at which you turn the machine on.”

New Zealand glaciers turn brown from Australian bushfires' smoke, ash and dust


The Guardian•January 1, 2020


New Zealand glaciers turn brown from Australian bushfires' smoke, ash and dust. Snow-capped peaks and glaciers discoloured as former PM says ash could accelerate glacial meltingMore

Snow and glaciers in New Zealand have turned brown after being exposed to dust from the Australian bushfires, with one expert saying the incident could increase glacier melt this season by as much as 30%.

On Wednesday many parts of the South Island woke up to an orange haze and red sun, after smoke from the Victorian and New South Wales blazes drifted east on Tuesday night, smothering many parts of the island for most of the day.

On Thursday, pictures taken from the Southern Alps showed the smoke haze carrying particles of dust had tinged snow-capped mountain peaks and glaciers a shade of caramel, with former prime minister Helen Clark expressing concern for the long-lasting environmental impacts on the mountains.

“Impact of ash on glaciers is likely to accelerate melting,” Clark tweeted. “How one country’s tragedy has spillover effects.”

There are more than 3,000 glaciers in New Zealand and since the 1970s scientists have recorded them shrinking by nearly a third, with current estimates predicting they will disappear entirely by the end of the century.

Professor Andrew Mackintosh is head of the school of earth, atmosphere and environment at Monash University, and the former director of the Antarctic Research Centre.

He said in nearly two decades of studying glaciers in New Zealand he had never seen such a quantity of dust transported across the Tasman, and the current event had the potential to increase this season’s glacier melt by 20-30%, although Mackintosh stressed this was no more than an estimate.

“It is quite common for dust to be transported to New Zealand glaciers, but I would say that the amount of transport right now is pretty phenomenal – I don’t think I’ve ever seen anything like it,” Mackintosh said.“It is concerning to me to see so much material being deposited on the glaciers.”

Mackintosh said the whiteness of snow and ice reflected the sun’s heat, and slowed melting. But when this whiteness was obscured the glacier could melt at a faster rate.

The higher glaciers around Mount Cook could likely get more snowfall soon, Mackintosh said, but the lower glaciers may not get another dump till March, and the dust would sit there until then, likely turning pink when algae began to grow.

The impacts of the dust event would likely last no longer than a year, Mackintosh said but if Australia continued to be impacted by extreme wildfires and droughts “it will be one of the factors that is accelerating the demise of glaciers in New Zealand overall”.

The recent smoke haze drifting over New Zealand is the fourth such event this summer, the Met Service said, and despite no official health warnings being issued, many with asthma said they were choosing to remain indoors during the unusual conditions.

The Met Service most of the smoke remaining over New Zealand would clear by Friday.

Early in December travel writer Liz Carlson took pictures of regions of the Southern Alps turning pink following exposure to smoke from Australia early in the bushfire season.

In a blog Carlson wrote: “It’s pretty remarkable to see the impact of the fires from so far away.”

“Our glaciers don’t need any more battles as they are already truly endangered; it puts the impact of climate change into even more stark reality we can’t ignore.”

Residents in Auckland and some parts of the North Island woke to an unusually bright orange sun on Thursday, thought to be a result of the bushfires 2,000km across the Tasman sea.
