Deep-Sea Dragonfish Transparent Teeth -- 1 (IMAGE)

Researchers Discover What Makes Deep-Sea Dragonfish Teeth Transparent

Jun 05, 2019 11:58 AM EDT

A team of researchers led by the University of California San Diego have discovered what's responsible for making the teeth of the deep-sea dragonfish transparent. This unique adaptation, which helps camouflage the dragonfish from their prey, results from their teeth having an unusually crystalline nanostructure mixed with amorphous regions.

Countries' Essential Medicines Lists Vary Greatly from One Another & WHO's Model List

Jun 03, 2019 08:31 PM EDT

Countries' essential medicines lists vary from one another and from the World Health Organization's (WHO) model list, pointing to a potential need for greater care in selecting medicines that best meet the health care priorities of a population, suggests a study led by Toronto's St. Michael's Hospital.

Co-Occurring Conditions Could Provide Useful Insights into the Underlying Mechanics of Autism (IMAGE)

Classification System Based on Co-occurring Conditions May Provide Insight into Autism

Jun 01, 2019 04:46 PM EDT

Children with autism spectrum disorder (ASD) are often affected by co-occurring conditions, such as epilepsy, immune disorders, gastrointestinal problems, and developmental delays. According to research published today in Autism Research, creating a classification system for ASD based on co-occurring conditions could provide useful insights into the underlying mechanics of ASD and these conditions.

Exposure to Airborne Metal Pollution Associated with Increased Risk of Mortality

May 31, 2019 10:55 AM EDT

Although there is ample evidence that air pollution--specifically airborne particulate matter--is associated with an increased risk of premature death, it is still not known which specific particles are responsible for this effect.

Study Could Improve Fire Monitoring in Brazilian Savana

May 29, 2019 01:49 PM EDT

A study conducted by scientists from Brazil, the United States, and Portugal investigated the accuracy and consistency of different satellite data collections with regard to the location and size of burned areas in the Cerrado biome, the Brazilian savanna.

E-cigarette Use, Flavorings May Increase Heart Disease Risk, Stanford-led Study Finds

May 27, 2019 04:01 PM EDT

The flavoring liquid for electronic cigarettes, or e-cigarettes, may increase the risk of cardiovascular disease when inhaled, according to a study led by researchers at the Stanford University School of Medicine.

Measuring Methane From Coal and Gas in Pennsylvania Informative

May 24, 2019 10:45 AM EDT

While methane pollution caused by natural gas production in Pennsylvania is underestimated by the U.S. Environmental Protection Agency, natural gas still has half the carbon footprint of underground coal mining, according to an international team of researchers.

New Studies Increase Confidence in NASA's Measure of Earth's Temperature

May 24, 2019 10:14 AM EDT

A new assessment of NASA's record of global temperatures revealed that the agency's estimate of Earth's long-term temperature rise in recent decades is accurate to within less than a tenth of a degree Fahrenheit, providing confidence that past and future research is correctly capturing rising surface temperatures.

Oldest Meteorite Collection on Earth Found in One of the Driest Places

May 23, 2019 02:16 PM EDT

Boulder, Colo., USA: Earth is bombarded every year by rocky debris, but the rate of incoming meteorites can change over time. Finding enough meteorites scattered on the planet's surface can be challenging, especially if you are interested in reconstructing how frequently they land. Now, researchers have uncovered a wealth of well-preserved meteorites that allowed them to reconstruct the rate of falling meteorites over the past two million years.

Eastern Forests Shaped More by Native Americans' Burning than Climate Change

May 22, 2019 10:18 AM EDT

Native Americans' use of fire to manage vegetation in what is now the Eastern United States was more profound than previously believed, according to a Penn State researcher who determined that forest composition change in the region was caused more by land use than climate change

CBD Clinical Trial Results on Seizure Frequency in Dogs 'Encouraging'

May 22, 2019 09:59 AM EDT

Promising and exciting. Those are the words used by Dr. Stephanie McGrath to describe findings from a pilot study to assess the use of cannabidiol, or CBD, for dogs with epilepsy.

Changes in Subsistence Hunting Threaten Local Food Security

May 18, 2019 11:40 AM EDT

Scientists with the Universidad San Francisco de Quito and WCS Ecuador Program publishing in the journal Biotropica say that subsistence hunting in Neotropical rain forests - the mainstay of local people as a source of protein and a direct connection to these ecosystems - is in jeopardy from a variety of factors.

Intensive Silviculture Accelerates Atlantic Rainforest Biodiversity Regeneration

May 18, 2019 11:35 AM EDT

An experiment conducted in Brazil in an area of Atlantic Rainforest suggests that intensive silviculture, including the use of herbicide and substantial amounts of fertilizer, is a more effective approach to promoting the regeneration of tropical forest and biomass gain than the traditional method based on manual weeding and less fertilizer.

UCLA-Led Team Develops 'Smart' Insulin (IMAGE)

'Smart' Insulin Could Prevent Hypoglycemia During Diabetes Treatment

May 17, 2019 10:24 AM EDT

UCLA bioengineers and their colleagues have developed a new type of insulin that could help prevent hypoglycemia in people who use the drug to manage diabetes.

Irregular Galaxy NGC 4485 (IMAGE)

Galaxy Blazes with New stars Born From Close Encounter

May 17, 2019 10:19 AM EDT

The irregular galaxy NGC 4485 shows all the signs of having been involved in a hit-and-run accident with a bypassing galaxy. Rather than destroying the galaxy, the chance encounter is spawning a new generation of stars, and presumably planets.
