Philadelphia, PA, June 23, 2016 - The majority of snakebites are often perceived as being "illegitimate," meaning they're a result of intentional human contact such as handling a snake in captivity or attempting to kill or move a wild snake; however, little data exists regarding how snakebite victims come in contact with these venomous predators. A new study in Wilderness & Environmental Medicine analyzed media reports of snakebites in the United States.

Research teams on both sides of the Atlantic have shown that precise modeling of the universe and its contents will change the detailed understanding of the evolution of the universe and the growth of structure in it.

One hundred years after Einstein introduced general relativity, it remains the best theory of gravity, the researchers say, consistently passing high-precision tests in the solar system and successfully predicting new phenomena such as gravitational waves, which were recently discovered by the Laser Interferometer Gravitational-Wave Observatory.

Washington, DC-- New work from Carnegie's Peter Driscoll suggests Earth's ancient magnetic field was significantly different than the present day field, originating from several poles rather than the familiar two. It is published in Geophysical Research Letters.

It is important to diagnose the faults of rolling bearings, because they may lead to the failure of motors, and even entire system-wide problems and failures. In order to diagnose the early faults of bearings, a novel method for early diagnosis of rolling bearing faults based on resonance-based sparse signal decomposition and principal component analysis is proposed in the present paper.

WASHINGTON -- Researchers from the Massachusetts Institute of Technology (MIT) and Australian National University have developed new technology that aims to make the Advanced Laser Interferometer Gravitational-Wave Observatory (LIGO) even more sensitive to faint ripples in space-time called gravitational waves.

A new study by Simon Fraser University marine ecologists Jessica Schultz, Ryan Cloutier and Isabelle Côté has discovered that a mass mortality of sea stars resulted in a domino effect on B.C.'s West Coast Howe Sound marine ecology.

Washington, DC-- Hydrogen is the most-abundant element in the universe. It's also the simplest--sporting only a single electron in each atom. But that simplicity is deceptive, because there is still so much we have to learn about hydrogen.

New images obtained on May 16, 2016, by NASA's Hubble Space Telescope confirm the presence of a dark vortex in the atmosphere of Neptune. Though similar features were seen during the Voyager 2 flyby of Neptune in 1989 and by the Hubble Space Telescope in 1994, this vortex is the first one observed on Neptune in the 21st century.

The discovery was announced on May 17, 2016, in a Central Bureau for Astronomical Telegrams (CBAT) electronic telegram by University of California at Berkeley research astronomer Mike Wong, who led the team that analyzed the Hubble data.

The GRAVITY instrument is now operating with the four 8.2-metre Unit Telescopes of ESO's Very Large Telescope (VLT - http://www.eso.org/public/teles-instr/paranal/) , and even from early test results it is already clear that it will soon be producing world-class science.

Roughly 90 percent of the biggest black holes in the known universe are dormant, meaning that they are not actively devouring matter and, consequently, not giving off any light or other radiation. But sometimes a star wanders too close to a dormant black hole and the ensuing feeding frenzy, known as a tidal disruption event, sets off spectacular fireworks.

Tropical Storm Danielle started weakening after making landfall north of Tuxpan, Mexico on Monday evening at 7 p.m. CDT. As Danielle weakened the low level circulation quickly became disorganized. The Global Precipitation Measurement or GPM mission core satellite looked at the quickly weakening storm's rainfall.

The GPM core observatory satellite passed above rapidly weakening Danielle on June 21, 2016 at 0421 UTC (12:21 a.m. EDT).

NEW HAVEN/STORRS, CT - As supplies of high-quality irrigation water become more limited, horticultural production operations are looking for alternative systems that can reduce water needs while ensuring healthy plants. A new study (HortScience, April 2016) of an "ebb and flow" subirrigation system, suggests that the method can be effective for controlling plant height and helping to alleviate salt stress in poinsettia, an ornamental known for its salt sensitivity.

A new study published in Nature presents one of the most complete models of matter in the universe and predicts hundreds of massive black hole mergers each year observable with the second generation of gravitational wave detectors.

The model anticipated the massive black holes observed by the Laser Interferometer Gravitational-wave Observatory. The two colliding masses created the first directly detected gravitational waves and confirmed Einstein's general theory of relativity.

Some 3.9 billion years ago in the heart of a distant galaxy, the intense tidal pull of a monster black hole shredded a star that passed too close. When X-rays produced in this event first reached Earth on March 28, 2011, they were detected by NASA's Swift satellite, which notified astronomers around the world. Within days, scientists concluded that the outburst, now known as Swift J1644+57, represented both the tidal disruption of a star and the sudden flare-up of a previously inactive black hole.

WASHINGTON -- Utilizing the Atacama Large Millimeter/submillimeter Array (ALMA), one of the most powerful telescopes in the world, U.S. Naval Research Laboratory (NRL) astrophysicist Dr. Tracy Clarke and an international team of researchers have peered into the feeding habits of a supermassive black hole and witnessed the first evidence of a new diet. The black hole, whose mass is nearly 300 million times that of our sun, is on the verge of gulping down massive clumps of cold gas which each contain as much material as a million suns.
