Researchers are using glow-in-the-dark materials to enhance and improve rapid COVID-19 home tests.
Much of the progress made in understanding the scope of bird deaths from building and window collisions has come as the result of citizen science, according to a newly published study. But the study also concludes that such grassroots efforts need more buy-in from government and industry, and better funding so they can keep a foot on the gas in their efforts to reduce bird-window collisions.
Researchers have developed a new 'camera' that sees the local disorder in materials. Its key feature is a variable shutter speed: because the disordered atomic clusters are moving, when the team used a slow shutter, the dynamic disorder blurred out, but when they used a fast shutter, they could see it. The method uses neutrons to measure atomic positions with a shutter speed of around one...
A research team has shed new light on the importance of plant roots for below-ground life, particularly in the tropics. Millions of small creatures toiling in a single hectare of soil including earthworms, springtails, mites, insects, and other arthropods are crucial for decomposition and soil health. For a long time, it was believed that leaf litter is the primary resource for these animals....
Machine learning can be valuable in supporting sustainable development of biomass if it is applied across the entire lifecyle of biomass and biomass-derived products, according to a new study.
After 2 weeks of intense negotiations, countries agreed this week on a historic treaty to protect biodiversity in international waters. The agreement, announced on 4 March at the United Nations, sets up a legal process for establishing marine protected areas (MPAs), a key tool for protecting at least 30% of the ocean, which an intergovernmental convention recently set as a target for...
Faunal organisms such as the humble mussel often play an underappreciated yet important role in protecting and building coastal ecosystems, according to a new study led by the Carbon Containment Lab at the Yale School of the Environment.
Researchers are coming to understand that the best performing materials in sustainable energy applications, such as converting sunlight or waste heat to electricity, often use collective fluctuations of clusters of atoms within a much larger structure. This process is often referred to as "dynamic disorder."
It's been long known that the air quality of Cache Valley is among the worst in the nation, but what exactly makes it so bad? The answer: ammonium nitrate.
Choosing a brand name for a new product or service is one of the most important marketing decisions a company makes. In recent years, brand strategists have recommended companies use unconventional spellings of otherwise familiar words—e.g., "Lyft" rather than "Lift."
A study published in Immunity by physician-scientist Read Pukkila-Worley, MD, and MD/Ph.D. students Nicholas D. Peterson and Samantha Y. Tse describes a new manner of detecting microbial infection that intercepts pathogen-derived signals of growth to assess the relative threat of virulent bacteria.
A new study from Assistant Professor in the Department of Social Work Melissa Villodas found that for Black youth who interacted with the juvenile justice system, mental health symptoms worsened during transition to adulthood (when youth were about ages 19-20). This highlights the transition to adulthood as a key time to provide supportive interventions that reduce mental health challenges.
The selective breeding of grain crops is one of the main reasons why domesticated plants produce such excellent yields. Selecting the best candidates for breeding is, however, a remarkably complex task. On one hand, it requires a skilled breeder with trained eyes to assess plant resistance to disease and pests, crop growth, and other factors. On the other hand, it also requires precise...
A new RAND Corporation report finds that the basic infrastructure to support elementary (grades K-5) social studies instruction—academic standards, accountability requirements, assessment programs—is inadequate in many states. Even where state-level infrastructure to guide teachers' instruction is in place, its comprehensiveness and quality vary greatly.
Cracking carbon bonds is a notoriously difficult problem, but it may hold the key to generating greener, more sustainable chemicals. A Chinese research team achieved the first visible-light-promoted simultaneous cleavage of carbon-carbon and carbon-nitrogen bonds via a silver-modified polyoxometalate photocatalyst, unlocking avenues for applications like carbon-neutral alternatives for fossil...
A new study in the Proceedings of the National Academy of Sciences finds that large-scale fish releases negatively impact ecosystems as a whole, while offering little benefit and some harm to the species they seek to support.
High up in the canopy of the Brazilian rainforest, clinging unsteadily to its mother's back, a wild newborn bearded capuchin monkey with a non-functioning left leg was beating the odds. Observations of the disabled infant monkey and his mother gave researchers a rare glimpse into care in an arboreal environment.
A research team, affiliated with UNIST has unveiled a key factor involved in the DNA damage response (DDR), homologous recombination (HR) and DNA interstrand crosslink (ICL) repair. According to the research team, their findings are expected to establish an effective control environment for chromosome instability (CIN), a major factor in cancer evolution, and further help combat malignant tumors .
Sustainable energy solutions cannot be pulled out of thin air. However, combining air with metal and other frameworks may pave the way for environmentally friendly energy conversion and storage, according to a research team based in China.

A pilot project has estimated emissions and removals of carbon dioxide in individual nations using satellite measurements.
Chip-scale miniaturization of spectrometers allows rapid detection of spectral information in portable devices, opening up new applications. However, integrated spectrometers typically suffer from a trade-off between spectral resolution and optical bandwidth.
With global warming on the rise, the severity and frequency of extreme weather events are also rising dramatically; this includes an increase in the number of compound extreme events. The latter term describes scenarios in which bad weather and climate events combine together, making the event more devastating than a separate weather and climate event.
Space travel has always tested the human body by the effects of the new conditions of altered gravity on biological systems. It has long been known that continuous exposure to microgravity conditions human physiology and causes effects that compromise muscular, sensory, endocrine and cardiovascular functions. But is it also risky to be exposed to altered gravity for short periods of time?
Macrophages are highly specialized cells of the immune system that help the body detect and fight deadly pathogens. In particular, M1-like macrophages detect and destroy tumor cells, and release protective chemokines such as interleukin (IL)-6 and tumor-necrosis factor α (TNF α), thus shielding the body from life-threatening pathologies like cancer.
The Phlegraean volcanic fields just west of Naples, Italy, are among the top eight emitters of volcanic carbon dioxide in the world. Since 2005, the Solfatara crater—one of many circular depressions in the landscape left by a long history of eruptions—has been emitting increased volumes of gas.
NASA is on track to launch a crewed mission around the Moon in November of next year after a successful unmanned test flight, the US space agency said Tuesday.
Nearly 5 years after a Chinese scientist sparked worldwide outrage by announcing he had helped create genetically edited babies, China has unveiled new rules aimed at preventing a repeat of such ethically problematic research on humans. Many researchers welcome the new regulations, which set requirements for ethics reviews of research involving humans and human materials such as...
Invisibility is a salient and recurring experience of mistreatment for women of color working in traditionally white and male professions, two researchers found in their recent study. Barnini Bhattacharyya of the Ivey Business School at Western University and Jennifer Berdahl of University of British Columbia looked at a diverse sample of 65 women of color in Canada and the U.S. for the study.
Simon Fraser University scientists say their research on the latest fossil find near Princeton, B.C. is raising questions about how the dispersal of animals and plants occurred across the Northern Hemisphere some 50 million years ago, including whether brief intervals of global warming were at play.
