New calculations predict that the Laser Interferometer Gravitational wave Observatory (LIGO) will detect approximately 1,000 mergers of massive black holes annually once it achieves full sensitivity early next decade.
The prediction, published online June 22 in the journal Nature, is based on computer simulations of more than a billion evolving binary stars. The simulations are based on state-of-the-art modeling of the physics involved, informed by the most recent astronomical and astrophysical observations.

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.

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.

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.

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.

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.
