Young female orphan elephants have a tougher social life than non-orphans, a new study suggests, adding to a growing body of evidence of how the impacts of poaching cascade through elephant societies.

Secondhand smoke linked to poor health, higher absenteeism, increased likelihood to seek medical attention among adolescents.

The critical, structural changes that enveloped viruses, such as HIV, Ebola and influenza, undergo before invading host cells have been revealed by scientists using nano-infrared spectroscopic imaging.

With a new research plane and a new base to improve its chances of outsmarting Atlantic hurricanes, NASA's Oceans Melting Greenland campaign takes to the sky this week for its third year of gathering data on how the ocean around Greenland is melting its glaciers.

For the past decade, Parkinson's disease researchers have relied on the experimental equivalent of using a sledgehammer to tune a guitar to test new therapies for the disease. This may be a reason clinical trials of promising neuroprotective drugs fail. But, in new research published today in Nature Parkinson's Disease, University of British Columbia researchers may have found the ideal tool for the job.

Researchers have used computer models on the Stampede2 supercomputer to replicate the dispersal of gases from the April 4, 2017 chemical weapons attack in northwest Syria. The simulations were able to capture real world conditions despite a scarcity of information. Recently, the team developed a coarse model that uses seasonal conditions as background information to speed up calculations, reducing forecasting time from days to minutes.

In a novel system, underwater sonar signals cause vibrations that can be decoded by an airborne receiver.

A collagen formulation mixed with pancreatic cells is the first minimally invasive therapy to successfully reverse Type 1 diabetes within 24 hours and maintain insulin independence for at least 90 days, a pre-clinical animal study shows.

Nearly six percent of urinary tract infections analyzed by a California emergency department were caused by drug-resistant bacteria in a one-year study period.

After an earthquake, hurricane, tornado or other natural hazard, it's considered a win if no one gets hurt and buildings stay standing. But an even bigger victory is possible: keeping those structures operational. This outcome could become more likely with improved standards and codes for the construction of residential and commercial buildings, according to a new report.
