Scientists warn that 24 of Britain's butterfly species are in danger of dying out.
Diatoms are the most important producers of plant biomass in the ocean and help to transport carbon dioxide (CO2) from the atmosphere into the deep ocean and thus regulate our climate. Because diatoms rely on silica rather than calcium carbonate to build their shells, they were previously thought to benefit from ocean acidification -- a chemical change in seawater triggered by the increasing...
Researchers have taken the initial step in identifying what may be an effective way to detect gestational diabetes mellitus (GDM) earlier in pregnancy, potentially improving diagnosis and treatment for what is the most common disorder of pregnancy.

Each year, the world loses about 10 million hectares of forest—an area about the size of Iceland—because of deforestation. At that rate, some scientists predict the world's forests could disappear in 100 to 200 years.
While calcifying organisms like oysters and corals have difficulty forming their shells and skeletons in more acidic seawater, diatoms have been considered less susceptible to the effects of ocean acidification—a chemical change triggered by the uptake of carbon dioxide (CO2). The globally widespread tiny diatoms use silica, a compound of silicon, oxygen and hydrogen, as a building material for...
Traditional acousto-optic (AO) devices based on bulk crystal materials have weak energy confinement abilities for both photons and phonons, leading to a low AO interaction strength. Compared with bulk materials, photonic integrated circuits (PICs) allow surface acoustic waves (SAWs) to be well confined within the thin film used to disturb the guided light waves, exhibiting a high energy overlap...
Humble potatoes are a rich source not only of dietary carbohydrates for humans, but also of starches for numerous industrial applications. Texas A&M AgriLife scientists are learning how to alter the ratio of potatoes' two starch molecules—amylose and amylopectin—to increase both culinary and industrial applications.
Seven healthy habits and lifestyle factors may play a role in lowering the risk of dementia in people with the highest genetic risk, according to new research.

A gene called FMNL2 may explain why people with hypertension, diabetes, heart disease, or obesity have a greater risk of developing Alzheimer's disease.
Escaping imminent danger is essential for survival. Animals must learn a new environment fast enough for them to be able to choose the shortest route to safety. But how do they do this without ever having experienced threat in the new environment?
Since NASA's Perseverance rover landed on Mars, its two microphones have recorded hours of audio that provide valuable information about the Martian atmosphere.
In 2020, a commentary published in Cell urged the National Institutes of Health (NIH) to address long-standing funding disparities between Black and white researchers. According to a 2011 study, Black applicants were 10 percentage points less likely to receive NIH funding than white applicants. A feature article in Chemical & Engineering News, an independent news outlet of the American Chemical...
Over the past two decades, researchers have used big data and machine learning (ML) methods to provide insight relevant for equity valuation. Many of these studies either use or inform on accounting variables. In a paper published in KeAi's The Journal of Finance and Data Science, Doron Nissim, a Professor of Accounting at Columbia Business School in the U.S., has reviewed a selection of these...
A nanoparticle vaccine that combines two proteins that induce immune responses against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that has caused the global pandemic, has the potential to be developed into broader and safe SARS-CoV-2 vaccines, according to researchers in the Institute for Biomedical Sciences at Georgia State University.
When we look out into space, all of the astrophysical objects that we see are embedded in magnetic fields. This is true not only in the neighborhood of stars and planets, but also in the deep space between galaxies and galactic clusters. These fields are weak—typically much weaker than those of a refrigerator magnet—but they are dynamically significant in the sense that they have profound...
A new study shows how the brains of Egyptian fruit bats are highly specialized for echolocation and flight, with motor areas of the cerebral cortex that are dedicated to sonar production and wing control. The work by researchers at UC Davis and UC Berkeley was published May 25 in Current Biology.
Our family origins tend to shape our future in many ways. A Weizmann Institute of Science study, published today in Nature, found that the same holds true for blood vessels. The researchers discovered blood vessels forming from unexpected progenitors and went on to show that this unusual origin determines the vessels' future function.
Men taking either of the two most common oral medications for advanced prostate cancer who had also undergone hormone therapy to treat their disease were at higher risk of serious metabolic or cardiovascular issues than patients who were only receiving hormone therapy, researchers found.

Engineers have developed the smallest-ever remote-controlled walking robot -- and it comes in the form of a tiny, adorable peekytoe crab. Just a half-millimeter wide, the tiny crabs can bend, twist, crawl, walk, turn and even jump. Although the research is exploratory at this point, the researchers believe their technology might bring the field closer to realizing micro-sized robots that can...
Most people carry the fungus Candida albicans on their bodies without it causing many problems. However, a systemic infection with this fungus is dangerous and difficult to treat. Few antimicrobials are effective, and drug resistance is increasing. An international group of scientists, including Albert Guskov, associate professor at the University of Groningen, have used single-particle cryogenic...
