Douglas-fir in Klamath Mountains are in ‘decline spiral’
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.
Emergence of extensively drug-resistant Shigella sonnei strain in France
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…
Biodiversity amid climate change
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.
Spotted lanternfly spreads by hitching a ride with humans
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.
Gigapixel 3D microscope captures life in unprecedented detail
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 o…
Study uses base editing to correct mutation that causes rare immune deficiency
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 …
Researchers uncover a protein deficiency in neurons of patients with neurodegenerative diseases that could be targeted by new gene therapy approach
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.
Advanced brain imaging study hints at how DMT psychedelic alters perception of reality
Scientists have gleaned new insights into how psychedelics alter conscious experience via their action on brain activity.
Can lymph nodes boost the success of cancer immunotherapy?
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.
In hot water: Ocean warming impacts growth, metabolic rate and gene activity of newly hatched clownfish
Future ocean warming and marine heatwaves could impact the growth and development of clownfish during their earliest life stages, suggests a new study.
Scientists use tardigrade proteins for human health breakthrough
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 …
Recycling: Researchers separate cotton from polyester in blended fabric
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 material…
Real-world studies confirm effectiveness of bulevirtide to treat chronic hepatitis D
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-te…
Ultrafast beam-steering breakthrough
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.
Jellyfish size might influence their nutritional value
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 …
‘Fishing’ for biomarkers
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 — k…
Head-worn device can control mobile manipulators
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, …
