Using genomics to map illegal pangolin poaching from Africa to Asia
2023-12-14
Genomic analyses reveal illegal pangolin trafficking routes from origins in Africa to markets in Asia, researchers report. The approach offers new opportunities to monitor pangolin poaching in near real-time, allowing for targeted and more effective anti-trafficking measures. The illegal wildlife trade is a significant driver of global biodiversity loss. Of all the species poached and traded, the white-bellied pangolin (Phataginus tricuspis) is the world’s most trafficked mammal and is at risk of extinction. Pangolins are in high demand in Asia because their scales are believed, without scientific support, ...
Solar-powered clothes provide personal heating and cooling
2023-12-14
Combining a flexible solar cell with an electrocaloric device, researchers have created solar-powered clothing that allows the body to adapt dynamically to changes in ambient temperature, according to a new study. The new device could help guarantee the safety and comfort of the human body amid fluctuating environmental temperatures and even extend survivability in extreme environments, like those in outer space or other planets. Clothing is the most common way humans regulate their body temperature relative to the environment. However, it is normally focused on keeping an individual either warm or cool. The ability of clothing to ...
Reaching for the (invisible) stars
2023-12-14
Supernovae–stellar explosions as bright as an entire galaxy–have fascinated us since time immemorial. Yet, there are more hydrogen-poor supernovae than astrophysicists can explain. Now, a new Assistant Professor at the Institute of Science and Technology Austria (ISTA) has played a pivotal role in identifying the missing precursor star population. The results, now published in Science, go back to a conversation the involved professors had many years ago as junior scientists.
Some stars do not simply die down, but explode in a stellar blast that could outshine ...
How can Europe restore its nature?
2023-12-14
The ‘Nature Restoration Law’ (NRL) requires member states of the EU to implement restoration measures on at least 20 per cent of land and marine areas by 2030, and in all ecosystems in need of restoration by 2050. This includes specific targets to rewet peatlands and to increase pollinator populations. The NRL has already overcome various hurdles: most recently, it was approved by the EU Parliament’s Environment Committee, after delegations of the Parliament and the Council negotiated the final text.
But will the regulation really achieve its aims? The authors, including scientists leading large European projects on ...

SNAP recipients may struggle to meet dietary goals, especially in food deserts
2023-12-14
The Supplemental Nutrition Assistance Program (SNAP) is the nation’s largest nutrition program, helping 41 million participants afford “nutritious food essential to health and well-being.”
But a new study from the University of Notre Dame found that SNAP participants in low-income households may not be able to meet the nutrition levels set by the Dietary Guidelines for Americans (DGA).
The case study set out to examine whether SNAP participants would be able to afford a healthy diet based on DGA’s recommended nutritional values. The DGA was created by the U.S. Departments of Agriculture and Health and Human ...
Researchers pave the way for next generation COVID-19 immunization strategies
2023-12-14
BOSTON – The global COVID-19 vaccination campaign saved an estimated 20 million lives. However, while current COVID-19 vaccines provide protection against developing severe disease, they do little to prevent infection and transmission.
Findings published in the journal Nature by physician-scientists at Beth Israel Deaconess Medical Center (BIDMC) and colleagues suggest that it may be possible to improve protection against COVID-19 by delivering the vaccine directly to the respiratory tract— the primary site of entry in SARS-CoV-2 infection.
“The ...
Improving treatment for opioid use disorder
2023-12-14
In the fatal world of opioid use disorder (OUD), pharmacotherapy, or using a prescribed medication to treat drug dependence, has emerged as the gold standard of treatment. Among the trio of FDA-approved medications to treat OUD, buprenorphine is the newest highly effective drug that can suppress and reduce cravings for opioids. It is also the first medication that physicians can prescribe without requiring a special waiver from the DEA, enabling outpatient use and substantially increasing treatment accessibility.
Despite its widespread usage, with 1 million buprenorphine prescriptions filled in 2018, it is not without side effects. When taken sublingually (under ...
Thinking about God inspires risk-taking for believers, York University study finds
2023-12-14
Thursday Dec. 14, 2023, Toronto – Does thinking about faith make religious people more likely to take leaps? A new study lead by York University’s Faculty of Health says yes, finding that participants were more likely to take risks when thinking about God as a benevolent protector.

Move over Blitzen: geese outpace reindeer impacts on Arctic ecosystems
2023-12-14
In the frigid seas halfway between mainland Norway and the North Pole, two types of animals browse the palatable vegetation of a high-tundra archipelago, munching on thick moss, cropped grasses and low-lying shrubs. New research from a group led by Matteo Petit Bon from the Quinney College of Natural Resources is working to untangle the ecosystem impacts that two major players — geese and reindeer — have on a changing and vulnerable Arctic system.
Reindeer have been year-round residents on the islands of Svalbard for thousands of years, but at one point were almost completely gone. Svalbard ...
Research shows disadvantaged people wait significantly longer for power restoration after major storms
2023-12-14
Hurricanes and other extreme weather events often affect disadvantaged communities more severely, and extended power outages are some of the most harmful effects. Concerns over the intensification of hurricanes has led to new environmental justice policies that aim to mitigate the unequal impacts of major storms. Now, policy experts and engineers are directing their attention toward illuminating the causes.
Researchers at the Georgia Institute of Technology sought to investigate whether socioeconomically vulnerable households experienced longer power outage durations after extreme weather events. The team analyzed data from the top eight major Atlantic hurricanes between 2017 ...

Jurors recommend death penalty based on looks, but new training can correct the bias
2023-12-14
Certain facial features—like downturned lips and a heavy brow—are known to make someone appear untrustworthy to others, even though these do not indicate a person’s actual character. Such facial biases influence our everyday social interactions as well as high-stakes decisions, including who we hire, or elect to political office.
But a new study by Columbia researchers shows that the effects of these judgments can be mitigated. The study outlines the results of four experiments that the authors conducted with 1,400 volunteers. Through those experiments, the researchers found that when real-world defendants have facial features that appear untrustworthy, they are more likely ...
Closing the design-to-manufacturing gap for optical devices
2023-12-14
Photolithography involves manipulating light to precisely etch features onto a surface, and is commonly used to fabricate computer chips and optical devices like lenses. But tiny deviations during the manufacturing process often cause these devices to fall short of their designers’ intentions.
To help close this design-to-manufacturing gap, researchers from MIT and the Chinese University of Hong Kong used machine learning to build a digital simulator that mimics a specific photolithography manufacturing process. Their technique utilizes real data gathered from the photolithography system, so it can more ...
Seals stay warm and hydrated in the arctic with larger, more convoluted nasal passages
2023-12-14
Arctic seals have evolved many adaptations to cope with their frosty environment—one that you might not immediately think of is the bones in their nasal cavity. Arctic seals have more convoluted nasal passages than seal species that live in milder environments, and researchers report December 14 in the Biophysical Journal that these structures help the seals more efficiently retain heat and moisture as they breathe in and out.
“Thanks to this elaborate structure in their nasal cavities, Arctic seals lose less heat through nasal heat exchange than subtropical seals when both are exposed to the same ...
D-mannose reduces age-triggered changes in urinary tract that increase susceptibility to UTIs
2023-12-14
Aging poses a number of challenges to the body’s well-being, one of the most important being an increased susceptibility to multiple diseases, including urinary tract infections (UTIs). The connection between aging and more prevalent UTIs is not well understood, but now researchers at Baylor College of Medicine have found an explanation.
The researchers show in the journal Developmental Cell that, compared to the younger counterpart, the aging urinary tract in animal models changes how it functions at the cellular level in ways that seem to favor the establishment ...
Where patients live impacts whether they pick up their heart-failure medications
2023-12-14
People who live in neighborhoods with higher levels of poverty and unemployment are less likely to fill their heart-failure drug prescriptions than those living in wealthier areas, a new study shows. The findings not only add to understanding geographic and economic disparities in heart disease care, but also point to new ways to address barriers for patients taking these lifesaving drugs.
Led by researchers at NYU Grossman School of Medicine, the study explored prescription pickup patterns among patients with systolic heart failure, a chronic, life-threatening ...
Animal behavior: Cats like to fetch when they’re feline playful
2023-12-14
Cats tend to dictate games of fetch with their owners and most cats who play fetch learned to do so without explicit training, according to a survey of 924 cat owners published in Scientific Reports. The findings also highlight the variety of objects that cats prefer to fetch, including hair ties and bottle parts.
Jemma Forman, Elizabeth Renner and David Leavens surveyed cat owners who reported fetching behaviours in 1,154 cats that they currently or previously owned. Owners reported how fetching first occurred, how often it occurs ...
New understanding of ancient genetic parasite may spur medical breakthroughs
2023-12-14
A multidisciplinary study published in Nature has elucidated the structure of the machinery responsible for writing much of our “dark genome” — the 98 percent of our DNA that has largely unknown biological function. These results may spur entirely novel treatments for autoimmune diseases, cancer and neurodegeneration.
An international team of scientists from Rutgers and more than a dozen other institutions, including both academia and industry, have published the first high-resolution images and structural details of avirus-like element known as LINE-1. They describe it as “an ancient genetic parasite” that is one of the most common parts of human DNA (video ...
