When many of us think about how drugs work in the body, we may first think about how a drug gets into the body, such as a pill versus an injection. In the Gellman Group at the UW–Madison Department of Chemistry, researchers are instead thinking about how a drug behaves after it
Pterosaurs, the first vertebrates to fly, would have had more diverse wing shapes than current scientific reconstructions suggest, according to new University of Bristol-led research. The study is published in the journal Paleobiology.
Which farming strategies can help agricultural operations better manage yield risks caused by climate change and fluctuating prices in the agricultural product market? A new study by ZALF published in the journal Agricultural Systems uses model calculations to show that farms
How could we noninvasively distinguish between healthy and cancerous tissue? And how could we increase the speed of wireless communications? These two seemingly unrelated questions may share the same answer: terahertz (THz) light. Spanning frequencies between 0.3 and 20 THz,

Researchers at Northumbria University have produced new economic evidence demonstrating the significant and growing commercial value of alternatives to animal testing in the U.K., with findings already featuring in parliamentary debate on the issue.
Some insects and microbes develop symbiotic partnerships that become so interdependent they can no longer survive without each other. But how specific are these heritable symbioses? Is it possible for the same species of bacteria to flourish across different species of insect
A new study conducted by scientists at the University of Sheffield in collaboration with researchers from UT Southwestern Medical Center in the U.S. has found a protein that could help guide which cells chemotherapies target. The findings, published in Molecular Cell, open up a
Astronomers using NASA's Hubble Space Telescope have found something they never expected—ultraviolet light from a galaxy that existed just 1.4 billion years after the Big Bang. That galaxy contains tightly clustered young stars that produce ionizing light capable of
Heat is no longer a future climate risk. It is already here.
Researchers have discovered how certain photosynthetic bacteria use a sophisticated quantum mechanism to increase their efficiency when capturing sunlight. The study, published today in the journal Nature Chemistry and led by Professor Jenny Clark, reveals that nature has been

A new optical technique developed by researchers at the University of St Andrews and Adelaide University allows toxic methanol in alcoholic spirits to be detected without opening the bottle. Published in the Journal of Physics: Photonics, this new work offers a powerful new
A lot of things need to go right on a molecular level for immune cells to launch an adaptive response to an infection. B cells can produce different classes of antibodies tailored for specific infections through controlled DNA damage and repair that alter the genetic
Ice formation can damage biological samples, tissues and materials during freezing and thawing. In nature, specialized molecules known as ice-binding proteins prevent ice crystals from growing too large, helping organisms survive in extreme cold. Scientists have long tried to
A McGill University study suggests that diversifying crops and replacing annual wheat with a perennial grain could help protect soil health as climate change brings more variable rainfall. The research is published in the journal Applied Soil Ecology.
The modern Colorado moose is often considered just that: modern—brought to the state by wildlife officials in the late 1970s, preceded by very occasional reports of moose sightings in the 19th and early 20th centuries.
Medications can save lives, yet for some drugs, the concentration in a patient's bloodstream determines whether a treatment is effective or whether harmful side effects may occur. Researchers at the Leibniz Institute of Photonic Technology (Leibniz IPHT) in Jena, Germany, have
A new study published in Nature provides the most detailed picture to date of Neanderthal diversity in Western Europe shortly before their extinction.
People make financial choices to avoid losing money or experiencing regret, rather than simply balancing expected monetary returns with their tolerance for financial risk, according to a new study led by Lisa Posey, associate professor of risk management in the Penn State Smeal

How does your body produce millions of antibodies from one genome? New research reveals how two closely related proteins help immune cells fold DNA, connecting distant genetic pieces to create diverse antibodies that help fend off disease.
Researchers have developed a chip-based metasurface biosensor that can detect traumatic brain injury (TBI) biomarkers at extremely low levels. With further development, the technology could one day help doctors make a faster diagnosis after a head injury, helping to guide
At first glance, bat sea stars, the nubbly, orange, many-footed creatures often found on the seafloor, seem about as far from humans as one can get. Appearances can be deceiving, however. Scientists have found evidence showing human and sea star ovaries share similar genetics,
Sight-threatening antibiotic-resistant eye infections are becoming a significant threat to vision in dogs, cats and horses, according to a new comprehensive review published in Veterinary Ophthalmology by researchers from the Hebrew University of Jerusalem. The study examines
Many bat species emit echolocation calls and use the returning echoes to find their way, detect the presence of fluttering insects, and locate and catch them. A new study investigated this behavior in greater horseshoe bats foraging in the wild. An international team, including
A University of Houston engineering professor is helping cities, utilities and transportation agencies prepare for and recover from natural disasters. All these organizations face the same challenge: They know the next hurricane, flood, wildfire or other major disruption will
In 1938 and 1944, two major hurricanes struck Long Island, and after the initial winds subsided, the surges came back unexpectedly hours later, leading observers to wonder whether this was a tsunami. In a study appearing in Continental Shelf Research, scientists at Stevens
The past five years have not been easy for the people of the Pacific. COVID restrictions disrupted tourism and upended supply chains, while global fuel shocks raised prices and hit island economies hard.
Bumblebees are only an inch long, but they help power the global food system. Roughly one-third of the food we grow depends on pollinators like bees—and those bees are regularly decimated by pesticides.
Even in darkness, many animals retain a sense of orientation because their nervous system sustains a memory of heading encoded by the activity of head-direction (HD) cells. Animals continuously update this internal compass by temporally integrating angular head velocity relayed
Multicellular life depends on remarkable acts of cooperation. Every cell in the human body must sense what is happening around it, interpret signals from its neighbors and respond in ways that support the larger tissue. These chemical, physical and electrical messages help
In a primary school classroom, a 9-year-old reads aloud to the person next to them. When they stumble over a word, their partner encourages them to try again. Together, they discuss what might happen next. But the child isn't reading to an adult—a teaching assistant or
