PITTSBURGH, Sept. 23, 2019 - In March 2016, the Organ Procurement and Transplantation Network revised its criteria for prioritizing children awaiting heart transplantation in the U.S. with the intention of reducing the number of deaths on the waitlist, but a new study suggests unintended consequences.

The biodiversity buzz is alive and well in Fiji, but climate change, noxious weeds and multiple human activities are making possible extinction a counter buzzword.

Just as Australian researchers are finding colourful new bee species, some of them are already showing signs of exposure to environmental changes.

Flinders University PhD candidate James Dorey - whose macrophotography has captured some of Fiji's newest bee species - says the naming of nine new species gives researchers an opportunity to highlight the risks.

Researchers at Chalmers University of Technology, Sweden, have discovered a new aspect to the way that DNA binds itself, and the role played by hydrophobic effects. They show how small changes in water properties can delicately control the binding process. The discovery opens doors for new understanding in research in medicine and life sciences. The researchers’ findings are presented in the journal PNAS.

Researchers from CRG and IBEC in Barcelona use a technique called high-throughput mutagenesis to study Amyotrophic Lateral Sclerosis (ALS), with unexpected results.

Results showed that aggregation of TDP-43 is not harmful but actually protects cells, changing our understanding of ALS and opening the door to radically new therapeutic approaches.

The population of threatened southern sea otters in Elkhorn Slough, an estuary in Central California, has made a significant comeback as a result of Monterey Bay Aquarium's Sea Otter Program.

More people die during tornadoes in the Southeast than anywhere else in the United States. And still, a lot of people have misconceptions about their risk of being impacted by tornadoes, according to a new study published in PLOS One by researchers at the University of Tennessee, Knoxville.

Around the globe, communities are concerned with rain and storms. An area known as the "Maritime Continent," which includes major islands such as Sumatra, Java, Borneo, Papua New Guinea, along with a galaxy of smaller islands, experiences significant rainfall including periodic monsoonal rain, and flash flooding.

Leesburg, VA, September 20, 2019--According to an ahead-of-print article published in the December issue of the American Journal of Roentgenology (AJR), lifetime-certified diagnostic radiologists whose Maintenance of Certification (MOC) was not mandated by the American Board of Radiology (ABR) were far less likely to participate in ABR MOC programs--especially general radiologists and those working in smaller, nonacademic practices in states with lower population densities.

NORTHFIELD, Minn. -- If you wander outside on these late summer nights, you might hear the din of calling songs from field crickets. Male crickets produce these songs to attract their mates -- but they may also draw the attention of acoustically orienting parasitiod flies. The fly Ormia ochracea has evolved directionally sensitive ears to eavesdrop on the communication signals of field crickets. Crickets that are parasitized by these flies face almost certain death.

Two tropical cyclones are very close together near the coast of western Mexico. Hurricane Lorena was moving over the southern tip of Baja California, and Tropical Storm Mario was south of Lorena over the Eastern Pacific Ocean. NASA calculated the rainfall rates happening in both of those tropical cyclones.

NASA has the unique capability of peering under the clouds in storms and measuring the rate in which rain is falling. The Global Precipitation Measurement mission or GPM core satellite passed over the region from its orbit in space and measured rainfall rates in these storms.
