When it comes to the world’s climate, in the past decade, Earth keeps sending us its summer siren’s call. 

Annually, it’s mostly been a case of heeding the heat, and repeat. According to NASA, nineteen of the hottest years have occurred since 2000, with 2016 and 2020 tied for the hottest ever on record. This summer is already making worldwide headlines, with the UK scorching beyond 40 degrees Celsius (104.5 Fahrenheit) for the first time ever. 

More climate extremes are occurring. Earlier snowmelts affect the high-altitude areas, severe forest fires are increasing, while rain pulses, followed by dry periods, are becoming the norm. But if heat waves and severe droughts are trends that will continue to hold across the globe, what will the future bring to temperate forest and cropland regions of the world? 

Scientists are looking at the unique adaptations of desert life, which function by their own set of rules long considered to be unique to dry areas. Now, new research by an international team of scientists suggests that climate change is causing these “dryland mechanisms” to increasingly affect earth’s wetter areas, such as temperate regions’ croplands and forests. 

To better predict how the world’s wetter areas will operate in the future, the scientific team recommends that we can begin to apply the lessons learned from how life works in arid regions, according to new research published in the journal Nature Ecology and Evolution. The study was led by Jose Grünzweig of The Hebrew University of Jerusalem and co-authored by Arizona State University’s Heather Throop.  

“The new insights can contribute to advancing our adaptive capacity to withstand climate extremes and lessen their impacts on nature and people,” said Throop, a professor with a joint appointment in ASU’s School of Earth and Space Exploration and School of Life Sciences.  

Spurred by a recent meeting of the European Ecological Federation, the team compiled a list of the unique rules of life driving dryland ecosystems. Currently, more than a third of the Earth’s land area is drylands. Many of these key processes have been considered relevant only to arid regions, including: 

•    rapid cycling between wet and dry conditions that influence plant and animal activity,
•    redistribution of water in soils by plant roots,
•    and formation of living crusts on soil surfaces by microscopic organisms.

Overall, the team identified a dozen different dryland mechanisms affecting multiple processes, including vegetation distribution, plant growth, water flow, energy budget, carbon and nutrient cycling, and decomposition of dead material. 

“These dryland mechanisms are controlled by environmental factors, such as intense solar radiation, high temperatures, large bare patches between plants, and inconsistent availability of water,” said Throop. 

The mechanisms were also categorized as either more likely to be fast-responding – those that we might expect to see occurring from short-term drought (e.g., dry-wet cycles, heat and sunlight breaking down dead material) and slow-responding – those that would happen after decades of dry conditions (e.g., formation of living crust on soils) as a result of changes in plant distribution. 

“In the paper we present these 12 different dryland mechanisms that are really routine processes in drylands but aren’t commonly found in wet systems,” said Throop. “And then we categorized them in the paper based on how likely it is that these are going to happen in wetter systems in the future. What sort of changes would be required for us to start seeing those in wetter systems?”

What’s clear to the researchers is that a new, unprecedented pattern is emerging, one that was considered absent or insignificant in most biomes on Earth.  These dryland mechanisms are now, with increasing frequency, occurring in temperate regions. In the future, these also will likely increase in frequency and become more relevant due to warmer, drier conditions from climate change. 

For example, much of Europe experienced a severe drought and heat wave in summer 2018. As a result, the low plant cover in agricultural fields during this time likely led to desert-like biological processes occurring in these usually wet locations (see Denmark aerial image). 

“A lot of the corn and irrigated agriculture suffered,” said Throop. “There was dramatically decreased plant growth in those systems, which leads to more exposure of bare soil on the surface that’s not covered by plants.”

To better understand potential future ramifications of dryland mechanisms on things like vegetation distribution and decomposition of dead material, the team took its drylands’ data and modeled it to show how the forces driving drylands will increasingly apply to temperate regions under future climate conditions. 

“We can use mathematical models to predict how systems will behave under drier or hotter conditions, but we usually assume that the operating rules will stay the same even if the climate changes,” said Throop. “But right now, what our models don’t really take into account is what if the rules by the which the system works change?”

What happened when they fully took their dozen dryland mechanisms into account? 
The results, first and long-term consequences were stunning. For example, their models predict that the total non-dryland area with average topsoil temperature of >40C (>104F) is estimated to increase by about 17 million km2 (approximately equal to the total land area of the USA and Brazil) by the end of the century. 

“Breaking down dead material is important in ecosystems since it releases nutrients for new plant growth,” said Throop. “Typically, in wet systems this decomposition is driven by organisms such as bacteria that consume the dead material. In dry systems the rules are different -- we have a lot more influence of sunlight and high temperatures breaking down material that’s sitting on the surface.”

“So, instead of having biology driving that decay, we have physical processes driving it,” said Throop. “One of the big differences with dry systems is that because you don’t have many plants there’s a lot of open space and you have a lot of redistribution, with things like dead leaves blowing around on the soil surface and accumulating unevenly. Where in wet systems, those things are staying in place, and you have a much more even distribution of resources.”

Dry soil conditions will cause the emergence of some dryland mechanisms, such as redistribution of soil water via plant roots. Other mechanisms will respond to changes in vegetation, with more sparsely distributed vegetation increasing the prevalence of microorganisms forming soil surface crusts and increasing the role of sunlight in breaking down dead leaves. 

“What’s also clear is that some of these projected changes will occur in regions with large human populations, and, thus, will significantly affect the well-being of society in these regions,” said Throop. “We will need continued research and monitoring on ecosystem functioning under increasing frequency and severity of droughts and heatwaves in order to improve our understanding of the underlying emergent processes.” 

Ultimately, the researchers hope that a better understanding of these uniquely adapted desert systems will lead society to set realistic expectations for the future of historically temperate and wetter areas----before it’s too late to heed Mother Nature’s call. 


 

NSF, DOE grants fund UIC research to decarbonize cement manufacturing

Researchers investigate new methods to reduce carbon dioxide emissions

Grant and Award Announcement

Chemical engineers at the University of Illinois Chicago are investigating new methods to reduce carbon dioxide emissions from cement manufacturing.

Cement is one of the most widely used building materials, but its production is responsible for up to 8% of global emissions from carbon dioxide, representing a major challenge to the goal of reducing climate change. Despite ongoing efforts to research renewable energy options and new cementation methods, there is currently no clear pathway to carbon-neutral cement manufacturing. 

Now, thanks to two federal grant awards, UIC researchers and their collaborators from the University of Wisconsin-Madison and Pennsylvania State University are hoping to change this fact.

“We have a global problem with C02 emissions, and if you look at all the industrial processes and rank them from highest to the lowest in terms of producing C02, cement manufacturing is at the top,” said Meenesh Singh, assistant professor of chemical engineering at the UIC College of Engineering. “We cannot just stop using it because cement is so crucial for creating buildings, infrastructures, roads and many other places.”

One award, from the Department of Energy, will provide $2.3 million in support of research to develop a carbon-negative replacement for portland cement, the most commonly used type of cement. 

“We hope to turn the widely used and previously carbon-intensive building material into a carbon capture system,” said Singh, co-principal investigator of the DOE award.

The funding is awarded through the Harnessing Emissions into Structures Taking Inputs from the Atmosphere program, which was created to support the development of technologies that cancel out embodied emissions while transforming buildings into net carbon storage structures.

Singh’s research group will collaborate with scientists from UW-Madison and Penn State on the grant. The proposed project from the three universities uses carbon captured from the air through a process called distributed direct air capture with rapid mineral carbonation to convert industrial mineral wastes such as coal ash into a recyclable replacement for portland cement. The objective is to create a durable and versatile building material that permanently stores C02 through a process that pulls more carbon out of the air than is emitted.

“What we have done with this idea is take a waste material that we then make into a castable cement-like material, which does not release C02 but actually captures it,” Singh said. 

UIC is working on a high-throughput system that can test different types and levels of chemicals, which can be used with varied waste materials. 

Another award, $1.9 million from the National Science Foundation to UIC, UW-Madison and Fort Lewis College, will support the development of a sustainable way to produce calcium hydroxide, a critical ingredient for creating cement.

The process under development is known as LoTECH, for low-temperature calcium hydroxide process. It uses a low-temperature ammonia cycle to produce calcium hydroxide from industrial waste streams, such as crushed concrete and coal ashes. As a result, cement could be made into concrete in small, distributed plants or portable units, Singh said.

The LoTECH system also has potential to shorten supply chains and promote sustainability in the concrete industry, he said.

“You can think of this as a closed-looped, modular process,” said Singh, co-principal investigator of the NSF award. “It can be placed in the back of a truck, and wherever you have a supply of concrete after a building is demolished, this system can harvest the waste product and then manufacture new cement right on site.”

Singh added that sustainable calcium hydroxide could replace the traditionally used limestone as the calcium source, which offers a realistic way to quickly lower the carbon footprint of the existing cement industry by more than 50% by eliminating the thermal decomposition of limestone.

Reducing sugar consumption to achieve climate and sustainability goals

New ICTA-UAB study says that sugar taxation policies have the potential to meet environmental, social, and economic objectives.

Peer-Reviewed Publication

UNIVERSITAT AUTONOMA DE BARCELONA

Reducing sugar consumption would have important benefits in the fight against climate change, as well as in the recovery from the health and economic crises associated with the coronavirus pandemic. This is the conclusion of a study by the Institute of Environmental Science and Technology of the Universitat Autònoma de Barcelona (ICTA-UAB) that analyses the potential climate and sustainability co-benefits of reducing sugar consumption through redirecting existing sugar cropland to alternative uses.

The study, published today in the scientific journal Nature Sustainability, highlights that sugar taxation policies have the potential to meet these competing objectives as sugar is arguably one of the worst foods to eat from a health perspective while it has great potential for biofuel production.

The study, conducted by Lewis King and Jeroen van den Bergh from ICTA-UAB evaluates the reorientation of existing sugar cropland for alternative uses. The authors examine three scenarios, namely the EU reforesting its existing sugar cropland, the EU switching its sugar beet crops to ethanol production, and the EU exporting its excess sugar production while Brazil switches its sugarcane crops from sugar to ethanol production.

Calculations indicate that emissions could fall by 20.9–54.3 MtCO2e per year under the first scenario (figure). These savings would be double those from the second scenario and around four times higher than those under the third scenario.

The study finds that an EU-Brazil agreement with the EU focusing on sugar production from sugar beet and Brazil producing ethanol from sugarcane would provide the greatest environmental benefits to society. Sugarcane ethanol production has already proved to be an economically viable alternative to sugar in Brazil. The economic impact on farmers in both the EU and Brazil would therefore be minimal, resulting in an equitable specialisation across countries that provides welfare gains through reducing negative externalities. “It provides a clear example of how broad collaboration can help direct society in a more sustainable direction”, says ICREA research professor at ICTA-UAB, Jeroen van den Bergh.

Achieving this reduction in sugar consumption would likely involve a similar approach that has helped the EU considerably reduce its tobacco consumption over the past decades: education and policies aimed at behavioural change, with a serious role for taxation. Sugar taxation has been shown to be both effective and politically popular in countries such as the UK, and thus presents a promising policy instrument to indirectly contribute towards achieving climate change targets. Sugar taxation will not affect only end use but also reduce sugar use by production sectors, such as beverages.

“For sustainability policies to be both efficient and effective, we must consider the full impact across the three – environmental, social, and economic – pillars. Changing how we use sugar crops presents an appealing strategy from this perspective as sugar is arguably the least efficient crop to be used as food, apart even from its negative health impacts; moreover, it is the most efficient crop for biofuel from a net energy perspective”, states Lewis King, ICTA-UAB researcher and first author of the article.

Machines can learn from fables

USC’s Information Sciences Institute uses short stories with moral implications to test human-like reasoning in AI

Machines can learn from fables

If a friend told you they were feeling blue, would you think they were changing color?

Although this question may seem facetious, it offers a simple entry into the rich world of analogical reasoning, a tool that enables humans to generalize knowledge from familiar to novel situations. We see it in areas ranging from politics to medicine; it’s a cornerstone of our daily cognition. It can be as simple as a child tossing a beach ball, which they recognize is similar to a basketball; and as complex as a physician using previous case studies to determine a care plan for a patient.

Now, researchers at the USC Information Sciences Institute (ISI) are extending this thought process to machines.

A new paper, “Understanding Narratives through Dimensions of Analogy,” presented at the Qualitative Reasoning workshop, which is co-located with the International Joint Conference on Artificial Intelligence taking place on July 23, 2022, teaches artificial intelligence to make creative analogies through an ancient art form…fables.

“People working in AI have been trying to get the same level of reasoning that humans have into AI systems, and it is a really hard challenge trying to mimic the analogical reasoning humans take for granted,” explains Jay Pujara, USC ISI research lead and research assistant professor at the USC Viterbi School of Engineering.

The current dominant paradigm in AI is machine learning, which relies on applying existing knowledge to novel situations. This framework cannot support analogical reasoning, which has created a significant challenge for the researchers. This is partly because analogical reasoning relies heavily on relational thinking, which is how humans discern meaningful connections between items or situations that lack surface similarities.

For example, despite the apparent differences between summer and winter, one can reasonably conclude that the following is an analogous word pair: “the sun is to summer as the snow is to winter.” In essence, analogical reasoning unifies different concepts, thereby enabling us to extract meaning from the innumerable stimuli we encounter daily. Instead of drawing connections from appearance alone, we can thus make creative connections between existing and novel scenarios.

Since AI models lack analogical reasoning mechanisms, they struggle to understand, explain, or make generalizations about novel stimuli. Creating technology with analogical reasoning capabilities would enable AIs to evaluate the relevance and meanings of language, which has numerous real-world applications. An AI with human-like conversational and interpretive abilities could be used to teach students new concepts or create novel products based on consumer marketing data. These AIs have a transformational impact on society, such as alleviating traffic by analyzing the shortcomings of current infrastructures to generate improved freeway models.

Previous studies have had limited success developing AI with the capability to draw analogies. However, the technology failed to understand the implications of such analogies and could not make large-scale generalizations. The team at USC tackled this problem by experimenting with different techniques to train AIs to understand analogies present in Aesop’s fables, a collection of simple short stories that convey moral ideas. Using natural language processing (NLP) methods, they analyzed the fables to generate story pairs based on lexical and semantic similarities or the words and meanings present in the text.

Said Pujara: “We chose short stories with a moral purpose because often you find multiple fables with the same moral purpose and message at the end but are told in very different ways. So that means there is a semantic meaning of a fable, which is very different from the surface form it takes, and humans can see those links.”

While humans recognize that the same theme of greed links stories about a fox who steals and a merchant who hoards, the study found that it was difficult for AI systems to identify these analogies.

“Although the techniques we developed could be used to build analogical frameworks, the recent advancements on NLP are still not enough to reach human-level accuracies,” explains Thiloshon Nagarajah, the paper’s co-author and a USC Viterbi master’s student in computer science. Despite this, the team successfully cataloged the different ways in which humans approach analogies, which is a promising step towards the goal of creating AI with analogical reasoning capabilities.

A secondary finding of the study was that the researchers themselves had to deeply engage with one another when determining whether specific stories constituted an analogical pair. It turns out that analogical reasoning is a more subjective and interpretive space than anticipated, which “points to the fact that there are other phenomena that have not been fully explored in this paper,” said Filip Ilievski, another co-author and USC Viterbi research assistant professor.

One such phenomenon is the influence of prior knowledge on analogical reasoning tasks. When an individual encounters a novel situation, they use their personal experiences to make connections from the unknown to the known. Since every individual possesses a unique repertoire of knowledge and skills, analogical reasoning inevitably varies from person to person.  Ilievski suggests that by further exploring the nuances of human analogical reasoning, changes can be implemented to improve the design of AI technology.

This study offers a promising beginning to developing artificial intelligence with analogical reasoning capabilities. The utility of such AI technology goes well beyond short stories — potentially improving everything from education and public policy to art and urban design.

Using AI to train teams of robots to work together

When communication lines are open, individual agents such as robots or drones can work together to collaborate and complete a task. But what if they aren’t equipped with the right hardware or the signals are blocked, making communication impossible? University of Illinois Urbana-Champaign researchers started with this more difficult challenge. They developed a method to train multiple agents to work together using multi-agent reinforcement learning, a type of artificial intelligence.

“It’s easier when agents can talk to each other,” said Huy Tran, an aerospace engineer at Illinois. “But we wanted to do this in a way that's decentralized, meaning that they don't talk to each other. We also focused on situations where it's not obvious what the different roles or jobs for the agents should be.”

Tran said this scenario is much more complex and a harder problem because it’s not clear what one agent should do versus another agent.

“The interesting question is how do we learn to accomplish a task together over time,” Tran said. 

Tran and his collaborators used machine learning to solve this problem by creating a utility function that tells the agent when it is doing something useful or good for the team.

“With team goals, it's hard to know who contributed to the win,” he said. “We developed a machine learning technique that allows us to identify when an individual agent contributes to the global team objective. If you look at it in terms of sports, one soccer player may score, but we also want to know about actions by other teammates that led to the goal, like assists. It’s hard to understand these delayed effects.”

The algorithms the researchers developed can also identify when an agent or robot is doing something that doesn’t contribute to the goal. “It’s not so much the robot chose to do something wrong, just something that isn’t useful to the end goal.”

They tested their algorithms using simulated games like Capture the Flag and StarCraft, a popular computer game. 

You can watch a video of Huy Tran demonstrating related research using deep reinforcement learning to help robots evaluate their next move in Capture the Flag.

“StarCraft can be a little bit more unpredictable – we were excited to see our method work well in this environment too.”

Tran said this type of algorithm is applicable to many real-life situations, such as military surveillance, robots working together in a warehouse, traffic signal control, autonomous vehicles coordinating deliveries, or controlling an electric power grid. 

Tran said Seung Hyun Kim did most of the theory behind the idea when he was an undergraduate student studying mechanical engineering, with Neale Van Stralen, an aerospace student, helping with the implementation. Tran and Girish Chowdhary advised both students. The work was recently presented to the AI community at the Autonomous Agents and Multi-Agent Systems peer-reviewed conference.

The study, “Disentangling Successor Features for Coordination in Multi-agent Reinforcement Learning,” written by Seung Hyun Kim, Neale Van Stralen, Girish Chowdhary, and Huy Tran, appears in the Proceedings of the 21st International Conference on Autonomous Agents and Multiagent Systems held in May 2022.

  • Doctors, scientists band together to tweet and amplify accurate health information
  • Goal is to promote public health guidance, combat disinformation and counter harassment
  • Simple infographics created in both English and Spanish attempt to spread accurate information to groups who were not already seeing it
  • Illinois group now combatting false information on reproductive health, firearm violence

CHICAGO --- At the beginning of the COVID-19 pandemic, when false information about the virus began to spread on Twitter, physicians and scientists from Northwestern Medicine and other institutions banded together to combat the deadly misinformation and disinformation and support one another when they ultimately were attacked online for doing so. 

They formed a new type of professional organization—the health professional amplifier—to tweet accurate health and safety information about COVID-19 and amplify one another “to combat misinformation and drown out some of the noise,” said Dr. Regina Royan, first author of a new Northwestern Medicine paper explaining the genesis of these groups and a member of the Illinois-based health professional amplifier, IMPACT (Illinois Medical Professional Action Collaborative Team), which uses the verified Twitter handle @IMPACT4HC

In the paper, published July 22 in the Journal of Medical Internet Research, Royan and fellow medical professionals explain how successful this group has been and why it is an effective tool to disseminate accurate medical information and combat disinformation while minimizing the harm related to personal and professional harassment that can come with social media advocacy.

“The pandemic has been really taxing for health professionals,” said Royan (@ReginaRoyan), emergency medicine research fellow and clinical instructor of emergency medicine at Northwestern University Feinberg School of Medicine. “In addition to the emotional toll caring for these very sick patients, particularly in the early waves of the pandemic, the politicization around COVID-19 added another layer of stress for many of us. One thing we highlight in this paper is that these kind of groups can be a safe space for health professionals to talk about issues like harassment on social media to keep the fight against misinformation going.”

IMPACT and other health professional amplifiers are comprised of nurses, health economists, scientists, public health professionals and physicians, Royan said. They’ve endured public harassment and attacks after posting scientifically proven medical information about the COVID-19 virus and vaccines.

IMPACT has also created numerous easy-to-digest infographics in both English and Spanish around specific issues, such as the effectiveness of masking and social distancing, and how mRNA was used to create the Pfizer-BioNTech and Moderna COVID-19 vaccines. It is a creative way the group is trying to reach people who may not have been reading accurate health information, Royan said. 

“We know that COVID-19 has disproportionately affected the Latino population, and it’s been important to us to partner with community organizations like Illinois Unidos to ensure that we are also addressing misinformation with Spanish-language resources,” Royan said.  

The group has recently begun to combat false information about reproductive health issues following the U.S. Supreme Court’s overturning of Roe v. Wade. They’ve also started disseminating information about firearm injury, such as a recent tweet that stated, “Fact: Mental illness is not an effective predictor of gun violence against others.”

The study is titled, “Use of Twitter Amplifiers by Medical Professionals to Tackle Misinformation During the COVID-19 Pandemic.” Other Northwestern authors include Dr. Seth Trueger and Tricia Pendergrast.

Firms time announcements of data breaches to bury the bad news

New research calls for stricter regulations, transparency for consumers

Peer-Reviewed Publication

INSTITUTE FOR OPERATIONS RESEARCH AND THE MANAGEMENT SCIENCES

INFORMS Journal Management Science Study Key Takeaways:

  • New research finds firms strategically announce data breaches when the media is preoccupied so less public attention is drawn to it.
  • This strategy harms consumers because the stock market doesn’t “punish” firms for their error.
  • Strategically timing the announcement of data breaches reduces the median decline in market capitalization loss from $347 million to $85 million.

  

BALTIMORE, MD, July 26, 2022 – New research in the INFORMS journal Management Science finds that firms that have experienced data breaches intentionally stage the timing of such announcements around other significant breaking news as a means of reducing media coverage and minimizing public attention.

“We estimate that strategic timing reduces the median decline in market capitalization loss resulting from a data breach, from $347 million to $85 million,” says Sebastian Schuetz of Florida International University.

The study, “Data Breach Announcements and Stock Market Reactions: A Matter of Timing?” conducted by Schuetz and Jens Foerderer of the Technical University of Munich, finds that this strategy harms consumers because the stock markets do not adequately “punish” firms for their misbehavior. 

The work appears to show that strategic timing is most common in data breaches that are of greatest interest to consumers, such as those that are more severe and involve healthcare data, financial data and credentials. 

“Based on our findings, we recommend lawmakers mandate shorter disclosure deadlines, from the current 30-day deadline to just three days,” says Foerderer. “Strategic timing is harmful for consumers because it undermines the effectiveness of current U.S. data breach legislation: because consumers and investors receive less information about the occurrence of a data breach, less change is being promoted in firms to protect consumers against future security issues.”

UCLA scientists discover places on the moon where it’s always ‘sweater weather’

People could potentially live and work in lunar pits and caves with steady temperatures in the 60s

Peer-Reviewed Publication

UNIVERSITY OF CALIFORNIA - LOS ANGELES

Future human explorers on the moon might have 99 problems but staying warm or cool won’t be one. A team led by planetary scientists at UCLA has discovered shady locations within pits on the moon that always hover around a comfortable 63 degrees Fahrenheit.

The pits, and caves to which they may lead, would make safer, more thermally stable base camps for lunar exploration and long-term habitation than the rest of the moon’s surface, which heats up to 260 degrees during the day and drops to 280 degrees below zero at night.

Pits were first discovered on the moon in 2009, and since then, scientists have wondered if they led to caves that could be explored or used as shelters. About 16 of the more than 200 pits are probably collapsed lava tubes, said Tyler Horvath, a UCLA doctoral student in planetary science, who led the new research. Two of the most prominent pits have visible overhangs that clearly lead to some sort of cave or void, and there is strong evidence that another’s overhang may also lead to a large cave.

Lava tubes, also found on Earth, form when molten lava flows beneath a field of cooled lava or a crust forms over a river of lava, leaving a long, hollow tunnel. If the ceiling of a solidified lava tube collapses, it opens a pit that can lead into the rest of the cavelike tube.

Horvath processed images from the Diviner Lunar Radiometer Experiment — a thermal camera and one of six instruments on NASA’s robotic Lunar Reconnaissance Orbiter — to find out if the temperature within the pits diverged from those on the surface.

Focusing on a roughly cylindrical 100-meter–deep depression about the length and width of a football field in an area of the moon known as the Mare Tranquillitatis, Horvath and his colleagues used computer modeling to analyze the thermal properties of the rock and lunar dust and to chart the pit’s temperatures over a period of time.

The results, recently published in the journal Geophysical Research Letters, revealed that temperatures within the permanently shadowed reaches of the pit fluctuate only slightly throughout the lunar day, remaining at around 63 degrees. If a cave extends from the bottom of the pit, as images taken by the Lunar Reconnaissance Orbiter Camera suggest, it too would have this relatively comfortable temperature.

The research team, which also included UCLA professor of planetary science David Paige and Paul Hayne of the University of Colorado Boulder, believes the shadowing overhang is responsible for the steady temperature, limiting how hot things get during the day and preventing heat from radiating away at night. Meanwhile, the sunbaked part of the pit floor hits daytime temperatures close to 300 degrees, some 40 degrees hotter than the moon’s surface.

“Because the Tranquillitatis pit is the closest to the lunar equator, the illuminated floor at noon is probably the hottest place on the entire moon,” said Horvath.

A day on the moon lasts nearly 15 Earth days, during which the surface is constantly bombarded by sunlight and is frequently hot enough to boil water. Unimaginably cold nights also last about 15 Earth days. Inventing heating and cooling equipment that can operate under these conditions and producing enough energy to power it nonstop could prove an insurmountable barrier to lunar exploration or habitation. Solar power — NASA’s most common form of power generation — doesn’t work at night, after all. (NASA currently has no plans to establish an exploration base camp or habitations on the moon.)

Building bases in the shadowed parts of these pits allows scientists to focus on other challenges, like growing food, providing oxygen for astronauts, gathering resources for experiments and expanding the base. The pits or caves would also offer some protection from cosmic rays, solar radiation and micrometeorites.

“Humans evolved living in caves, and to caves we might return when we live on the moon,” said Paige, who leads the Diviner Lunar Radiometer Experiment.

Diviner has been mapping the moon continuously since 2009, producing NASA’s second largest planetary dataset and providing the most detailed and comprehensive thermal measurements of any object in our solar system, including Earth. The team’s current work on lunar pits has improved data from the Diviner experiment.

“Because nobody else had looked at things this small with Diviner, we found that it had a bit of double vision, causing all of our maps to a be a bit blurry,” said Horvath. The team worked to align the many images taken by the instrument until they could achieve an accurate thermal reading down to the level of single pixel. This process yielded much higher resolution maps of the moon’s surface.

Data from the early stages of this lunar pit thermal modeling project were used to help develop the thermal management system of the rover for NASA’s proposed Moon Diver mission. Horvath and Hayne were part of the science team for this mission, which aims to have the rover rappel into the Tranquillitatis pit to research the layers of lava flows seen in its walls and to explore any existing cave.

Horvath and Paige are science team members for a new lunar-bound thermal camera led by Paul Hayne named L-CIRiS, which will head to the lunar south pole in late 2023 to get the first ground-based thermal images.

Yoga app can reduce urinary incontinence

Yoga of Immortals app could provide a more accessible, easy-to-use, novel and effective treatment for urinary incontinence, Rutgers study finds

Peer-Reviewed Publication

RUTGERS UNIVERSITY

People with loss of urinary control who used the Yoga of Immortals mobile app – a globally used app that combines specific yogic postures in the Sanatan tradition with breathing exercises, sound therapy and meditation – found significant improvement in the frequency and severity of urine leaks at four weeks of practice, according to a Rutgers study.

Urinary incontinence is more common in women compared to men. An estimated 25 to 45 percent of women globally suffer from the condition, which can adversely affect quality of life and create difficulties in social, psychological and sexual functioning. However, only less than 20 percent of affected people seek treatment, which includes medications, pelvic floor muscle physical therapy to strengthen pelvic floor muscles or surgical procedures.

“Although these treatments are effective, there are many shortcomings: Medications have poor compliance and potential significant side effects; patients often lack the knowledge to identify specific pelvic muscles and motivation to complete physical therapy and the surgical procedures are invasive with potential complications,” said Hari Tunuguntla, lead author of the study and an Associate Professor of Urological Surgery at Rutgers, Robert Wood Johnson Medical School.

“However, the 30-minute daily app sessions are easy, safe, effective and convenient as they can be done anytime and anywhere without the need for in-person visits to the health-care provider,” he continued. “The app-based YOI practice involves specific breathing exercises, stimulation of the body’s specific energy centers for urinary control, postures to engage the pelvic floor, promote relaxation and muscle control, and alignment techniques to strengthen the pelvic floor.”

The researchers selected Yoga of Immortals for study as it provides precise video and audio instruction for this comprehensive program that engages the pelvic floor and specific energy centers of the urinary system. The YOI protocols have been shown in the study to be easily understood by participants at all education levels. YOI practice also includes breath work to enhance detoxification, mindfulness and meditation. YOI has also been shown to address mental health and quality-of-life issues resulting from depression, stress and anxiety.

The study, published in the journal Urology (the Gold Journal), is the first to the researchers’ knowledge to determine the efficacy of a mobile app-based Yoga of Immortals intervention for urinary incontinence on a global scale among various ages and ethnic groups in both men and women. (Tunuguntla also recently published a study in the journal International Journal of Environmental Research and Public Health that found people who used Yoga of Immortals reported it reduced their anxiety, depression and insomnia.)

In this study, the researchers sent a survey to app subscribers to identify those who were experiencing a loss of bladder control of different types – urine leak from not being able to reach the restroom in time or loss of urine after sneezing, coughing or laughing; or a combination – and of all types of severity of urine leak. The 258 subscribers from 23 countries between the ages of 18 and 74 – the majority being women and between 18 and 44 – were sent questionnaires at four weeks and eight weeks to report on condition improvement. The researchers then assessed their responses using specific questionnaires and the Patient Global Impression of Improvement scale, which measures the subjective efficacy of therapy.

The researchers found 76 percent of the respondents felt much better at four weeks with significant improvement in frequency and severity of urine leak without in-person visits to the healthcare provider – many of whom reported continuing improvement at eight weeks. Those with more severe leakage reported the most improvement in daily life activity and quality of life. Most of the study participants felt “much better” at the conclusion of the study.

The app can potentially increase adherence to treatment and may be used to complement other treatments, the researchers said.

“Due to its convenience, flexibility and efficacy, the app may increase access to care and serve as first-line treatment for both women and men with urinary incontinence. This is an easily accessible, self-management treatment,” Tunuguntla said. “However, further studies are needed to test the app’s efficacy in improving this condition long term.”

Researchers have created a profile of electric car purchasers and drivers

Main reason to buy ones is belonging to the eco-community and concern for the environment

An international group of experts has constructed a profile of today's electric vehicle buyers and drivers. Despite a lack of proper infrastructures, such as a sufficient number of charging stations, the researchers discovered that joining environmental communities and active engagement in them reduces reluctance to purchase an electric automobile. Economists published these and other findings in the Journal of Business Research.

"When we talk about electric car customers, we're talking about the so-called harbingers of change, people who love anything new, including technology." Furthermore, electric car owners are increasingly concerned about the environment and air quality. They are becoming more environmentally conscious. Simultaneously period, while consumers in large part tend to behave rationally, the decision to buy an electric car is influenced by the consumer's self-identification with the eco-society and concern for the environment," says co-author Alberto Ferraris, Senior Research Fellow at the Ural Federal University, Graduate School of Economics and Management.

The researchers conducted a bibliometric and thematic analysis of 254 studies published between 1983 and 2021. Even though there were no electric automobiles on the market in 1983, research on the usage of electric batteries was conducted. Even back then, the issue of low battery performance dictated the three primary variables that now influence electric vehicle customers' decisions: battery run and charge times, the electric car's overall performance, and its ultimate cost.

"Our study allows us to examine customer behavior from various angles. The most critical element is customer habits. Despite all of the perks associated with owning an electric automobile, the expensive price of these vehicles will prevent more people from making the switch. Consumers want electric vehicles with a large driving range, the quickest possible charging time, a high top speed, low levels of pollutant emissions, and the lowest possible pricing. Buying an electric car to get you and your family about town is quite a different purchase than, say, a new wardrobe. The fate of the electric car market rests on the price versus technological safety ratio”, advocates Alberto Ferraris.

Researchers highlight that the majority of current research focuses on the advantages of electric automobiles. As a result, electric vehicles appear to be one of the primary ecological solutions for future generations and mobility. Nevertheless, it is necessary to conduct a full investigation, which should also include a critical assessment of the proposed solution to the pollution problem.

"The widespread adoption of electric vehicles may cause an unmanageable uptick in demand, which would then be followed by an increase in the cost of energy. It's also important to keep in mind that electric car batteries, despite their energy efficiency, might release gas and other contaminants. In order to make conclusions regarding the efficacy of the decision to move from gasoline vehicles to electric cars, more study has to be done to analyze the association between purchasing an electric car and caring for the environment," argues Alberto Ferraris.

The experts also note that the European Union is home to the most developed electric car industry, where the shift to a "green path" has become a vital issue for all sectors of the economy and the younger generations. Consumer portrait studies can be helpful for the progression of this domain in nations that are just starting to investigate the subject matter regarding the manufacturing and sales of electric automobiles. These nations include countries in the Eastern as well as Russia. Furthermore, given the high cost of the final product, researchers advocate launching partner manufacturing methods and building internal motives for individual and corporate customers based on an examination of worldwide practices.
