Increases in mortality among Douglas-fir in the Klamath Mountains are the result of multiple factors that have the iconic tree in a 'decline spiral' in parts of the region.

Shigellosis, a highly contagious diarrheal disease, is caused by Shigella bacteria circulating in industrializing countries but also in industrialized countries. Scientists who have been monitoring Shigella in France for several years have detected the emergence of extensively drug-resistant (XDR) strains of Shigella sonnei.

Fewer parasites in U.S. waters might be seen by many as a good thing, but a biologist says the trend signals potential danger for fish and other wildlife.

Researchers have found that the spread of the spotted lanternfly population is largely due to human-mediated dispersal via transportation. In other words, these expert hitchhikers are catching rides on our cars, trucks and trains.

Researchers have developed a new type of microscope that stitches together video from 54 individual cameras and lenses. Whether recording high-speed, 3D, gigapixel movies of the behavior of dozens of freely swimming zebrafish or the grooming activity of fruit flies at near cellular-level detail across a very wide field of view, the device is opening new possibilities to researchers the world over.

A condition called CD3 delta SCID is caused by a mutation in the CD3D gene, which prevents the production of the CD3 delta protein that is needed for the normal development of T cells from blood stem cells. Researchers showed that a new genome editing technique called base editing can correct the mutation that causes CD3 delta SCID in blood stem cells and restore their ability to produce T cells....

Researchers discovered that a protein called Stathmin-2 is lost in these neurons, which prevents them from regenerating after injury and disrupts their connection with the muscles to control movements.

Scientists have gleaned new insights into how psychedelics alter conscious experience via their action on brain activity.

Cancer treatment routinely involves taking out lymph nodes near the tumor in case they contain metastatic cancer cells. But new findings from a clinical trial show that immunotherapy can activate tumor-fighting T cells in nearby lymph nodes.

Future ocean warming and marine heatwaves could impact the growth and development of clownfish during their earliest life stages, suggests a new study.

Natural and engineered versions of tardigrade proteins can be used to stabilize an important pharmaceutical used to treat people with hemophilia and other conditions without the need for refrigeration -- even amid high temperatures and other difficult conditions.

Researchers found they could separate blended cotton and polyester fabric using enzymes -- nature's tools for speeding chemical reactions. Ultimately, they hope their findings will lead to a more efficient way to recycle the fabric's component materials, thereby reducing textile waste.

In 2020, bulevirtide (BLV) was conditionally approved for treating chronic hepatitis delta (CHD), an inflammation of the liver caused by hepatitis D virus (HDV). Now real-world studies of patients treated outside of clinical trials confirm that long-term suppressive therapy with BLV monotherapy has the potential to reduce viral replication and improve liver tests of these difficult-to-treat...

n a major breakthrough in the fields of nanophotonics and ultrafast optics, a research team has demonstrated the ability to dynamically steer light pulses from conventional, so-called incoherent light sources.

Researchers confirmed what was already known: jellyfish eat bigger prey as they grow, which means they also occupy a higher position in the food web as they grow. They also found that some of the concentrations of 'healthy fats,' increase as jellyfish grow. These changes might be influenced by their diet, and as they feed on bigger prey with higher levels of fatty acids, the jellyfish accumulate...

Researchers have devised a tiny, nano-sized sensor capable of detecting protein biomarkers in a sample at single-molecule precision. Fittingly coined as 'hook and bait,' a tiny protein binder fuses to a small hole created in the membrane of a cell -- known as a nanopore ­-- which allows ionic solution to flow through it. When the sensor recognizes a targeted molecule, the ionic flow changes. This...

New research aims to increase autonomy for individuals with such motor impairments by introducing a head-worn device that will help them control a mobile manipulator. Teleoperated mobile manipulators can aid individuals in completing daily activities, but many existing technologies like hand-operated joysticks or web interfaces require a user to have substantial fine motor skills to effectively...

A team including physicists has for the first time detected subatomic particles called neutrinos created by a particle collider, namely at CERN's Large Hadron Collider (LHC). The discovery promises to deepen scientists' understanding of the nature of neutrinos, which are among the most abundant particles in the universe and key to the solution of the question why there is more matter than...

Cultivation and growth of grapevines have strongly influenced European civilizations, but where the grapevine comes from and how it has spread across the globe has been highly disputed so far. In an extensive genome project, researchers have determined its origin and evolution from the wild vine to today's cultivar by analyzing thousands of vine genomes collected along the Silk Road from China to...

Sunlight can be used to produce green hydrogen directly from water in photoelectrochemical (PEC) cells. So far, most systems based on this 'direct approach' have not been energetically competitive. However, the balance changes as soon as some of the hydrogen in such PEC cells is used in-situ for a catalytic hydrogenation reaction, resulting in the co-production of chemicals used in the chemical...

New research could help develop treatments to reduce cravings for unhealthy food.

Genes long known to control the formation of bones before birth also control bone healing later in life, a new study found.

A new study explores a record of birds' diets preserved in their feathers and radio tracking of their movements to find that birds eat far fewer invertebrates in coffee plantations than in forests, suggesting that the disturbance of their ecosystem significantly impacts the birds' dietary options.

A study used video games to test ways of balancing agriculture and conservation -- and found getting more women involved in decision-making may boost productivity and the planet's health.
