Vulnerable communities in the United States often face the highest risks from individual environmental burdens, such as exposure to toxic air pollutants. But new research shows that these communities are also exposed to a disproportionate number of multiple high-intensity
Organs often have fluid-filled spaces called lumens, which are crucial for organ function and serve as transport and delivery networks. Lumens in the pancreas form a complex ductal system, and its channels transport digestive enzymes to the small intestine. Understanding how
An international research team reveals new molecular mechanisms associated with pathogenic mutations in the protein transthyretin that cause transthyretin amyloidosis (ATTR), a group of fatal progressive diseases. The results, obtained thanks to a new methodological approach,

Evidence is mounting that specific gut bacteria are linked to sleep conditions, which may open the doors to dietary recommendations aiming to boost the quality of our slumbers
The elm zigzag sawfly has spread to 15 states in five years. Now it's attacking the tree that cities planted to replace Dutch elm disease victims.
Plant viruses pose a serious and ongoing threat to global agriculture in tropical to temperate regions. Among the most damaging are begomoviruses, a group of DNA viruses spread by whiteflies that infect many important food crops, including eggplant, tomato, pepper, cucurbit,
A research team from Osaka Metropolitan University proposed using a current-biased kinetic inductance detector with submicron 400 megapixels to image hot spots induced by a localized external stimulus over a 15 × 15 mm2 area. The team utilized a delay-line technique to trace
Crops increasingly need to thrive in a broader range of conditions, including drought, salinity, and heat. Traditional plant breeding can select for desirable traits, but is limited by the genetic variation that already exists in plants. In many crops, domestication and
Scientists have uncovered a new explanation for how swimming bacteria change direction, providing fresh insight into one of biology's most intensively studied molecular machines.
In high-intensity laser–matter interactions, including laser-induced particle acceleration, physicists generally want to work with the highest possible focused laser peak power, which is the ratio of energy per unit area to pulse duration. Therefore, for the same pulse energy
Every winter in the Ladakh region in northwest India, the two roads that connect the small villages in the Zanskar Valley with the rest of the country close, overwhelmed by snow. But for centuries, locals have had a workaround: a road of ice formed by the frozen Chadar River.
Researchers at the Indian Institute of Science (IISc), with collaborators from the Institute of Mathematical Sciences (IMSc), have discovered how a key protein in the tuberculosis bacterium helps protect it from the influence of foreign DNA inserted into its genome.
Over the decades, many strains of disease-causing bacteria have evolved defenses to even the most potent antibiotics, setting off a growing health crisis. The rise of antibiotic-resistant "superbugs" has also set off an arms race. As germs find new ways to withstand drugs,
