Douglas-fir in Klamath Mountains are in 'decline spiral'
Study gives most advanced picture yet of DMT compound’s effect on advanced functions such as imaginationThe brew is so potent that practitioners report not only powerful hallucinations, but near-death experiences, contact with higher-dimensional beings, and life-transforming voyages through alternative realities. Often before throwing up, or having trouble at the other end.Now, scientists have...

Emergence of extensively drug-resistant Shigella sonnei strain in France
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.

Biodiversity amid climate change
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.

Spotted lanternfly spreads by hitching a ride with humans
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.

Gigapixel 3D microscope captures life in unprecedented detail
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.

Study uses base editing to correct mutation that causes rare immune deficiency
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.

Researchers uncover a protein deficiency in neurons of patients with neurodegenerative diseases that could be targeted by new gene therapy approach
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....

Lack of canine COVID-19 data fuels persisting concerns over dog-human interactions
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.
After misconduct claims, star botanist has second paper retracted
Early COVID-19 pandemic suspicions about dogs' resistance to the disease have given way to a long-haul clinical data gap as new variants of the virus have emerged.
L.A. Youth Robotics Competition Leaves Student Teams Energized
Steven Newmaster, a prominent University of Guelph (UG) botanist and entrepreneur who has faced allegations of scientific misconduct, has had another paper retracted without his consent. Last week
Canadian Journal of Forest Research

Local manure regulations can help reduce water pollution from dairy farms
Astronomer says unusual sighting 99.9% certain to be due to burning space debris from International Space StationWeeks after a balloon, an “octagonal structure” and other flying objects put Americans on edge, the US is dealing with another mysterious phenomenon in the sky.On Friday night in Sacramento, St Patrick’s Day partiers spotted streaks of light blazing a path through the California...
New research shows the prevalence of 'himpathy' towards perpetrators of workplace sexual harassment
Animal agriculture is a major source of water pollution in the United States, as manure runoff carries excess nutrients into rivers and lakes. Because of their non-point source nature, most farms are not regulated under the federal Clean Water Act. This leaves pollution control up to the states, resulting in a patchwork of different approaches that are difficult to evaluate.
Workers' and bosses' trust in teleworking is key, says study
Managers spend much of their time managing conflict and struggle to know how to respond when a "he said, she said" workplace dispute occurs. However, a new study shows how employees' intuitive moral values might give rise to feelings of sympathy toward alleged perpetrators and anger toward their accusing victims. The research, published in Organization Science, also offers novel insights into what...
Astronomers sound alarm about light pollution from satellites
In recent years, teleworking—spurred by the implementation of information and communication technologies and the recent pandemic, particularly—has become a feature of many jobs. Many companies have now made this form of working available to their employees, but it is still far from common practice in today's labor market.
What Darwin couldn't see: Expedition to uncover invisible life in Galápagos
Astronomers on Monday warned that the light pollution created by the soaring number of satellites orbiting Earth poses an "unprecedented global threat to nature."
Douglas-fir in Klamath Mountains are in 'decline spiral,' research shows
An international research team led by the Netherlands Institute of Ecology (NIOO-KNAW) is to search for invisible life in the Galápagos Islands. The diversity of bacteria and other microscopic organisms may not be evident to the naked eye, but it is essential to nature; for example, to the islands' giant daisies, unique endemic plants that are currently under threat.
By studying lizards, researchers reveal the forces that shape biodiversity
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, a new study by the Oregon State University College of Forestry and OSU Extension Service indicates.
Discriminatory housing policies created an unequal park system in Minneapolis, new research shows
"If you pick a spot in, say, a rainforest, and count the number of different species of lizards within 15 meters and you come up with a number," asks Luke Mahler, "what determines that number?"
A cat's sociable personality and a clean litterbox appear to decrease litterbox issues
A new study by researchers at the University of Minnesota sheds light on the origins of racial disparities in the Minneapolis park system and their long-lasting consequences for environmental justice in the city.
Researchers at the University of Helsinki identified several links between various risk factors and feline litterbox issues. Identifying a range of risk factors makes it possible to modify conditions in the cat's environment, thus preventing and reducing litterbox issues.
