New research collaboration with UTSA professor challenges existing models of black holes

Fri, 19 Jan 18 00:14:00 -0800

Chris Packham, associate professor of physics and astronomy at The University of Texas at San Antonio (UTSA), has collaborated on a new study that expands the scientific community's understanding of black holes in our galaxy and the magnetic fields that surround them.



Real-world intercontinental quantum communications enabled by the Micius satellite

Fri, 19 Jan 18 00:01:50 -0800

A joint China-Austria team has performed quantum key distribution between the quantum-science satellite Micius and multiple ground stations located in Xinglong (near Beijing), Nanshan (near Urumqi), and Graz (near Vienna). Such experiments demonstrate the secure satellite-to-ground exchange of cryptographic keys with ?kHz rate during the passage of the satellite Micius over a ground station. Using Micius as a trusted relay, a secret key is created between China and Europe at locations separated up to 7,600 km on the Earth.



Neutron-star merger yields new puzzle for astrophysicists

Thu, 18 Jan 18 00:05:20 -0800

The afterglow from the distant neutron-star merger detected last August has continued to brighten - much to the surprise of astrophysicists studying the aftermath of the massive collision that took place about 138 million light years away and sent gravitational waves rippling through the universe. New observations from NASA's orbiting Chandra X-ray Observatory, reported in Astrophysical Journal Letters, indicate that the gamma ray burst unleashed by the collision is more complex than scientists initially imagined.



Viruses are everywhere, maybe even in space

Thu, 18 Jan 18 00:05:50 -0800

Viruses are the most abundant and one of the least understood biological entities on Earth. They might also exist in space, but as of yet scientists have done almost no research into this possibility. Portland State University biology professor Ken Stedman and colleagues are trying to change this through their article



Hubble weighs in on mass of 3 million billion suns

Tue, 16 Jan 18 00:00:30 -0800

In 2014, astronomers using the NASA/ESA Hubble Space Telescope found that this enormous galaxy cluster contains the mass of a staggering three million billion suns. Known officially as ACT-CLJ0102-4915, it is the largest, hottest, and brightest X-ray galaxy cluster ever discovered in the distant universe.



Ultrathin black phosphorus for solar-driven hydrogen economy

Tue, 16 Jan 18 00:11:10 -0800

Osaka University researchers combined two different types of 2-D materials -- black phosphorus and bismuth vanadate -- to form a biologically inspired water-splitting catalyst. Normal sunlight could drive the reactions and careful design of the catalyst enabled the expected ratio of hydrogen and oxygen production.



The brain's GPS has a buddy system

Thu, 11 Jan 18 00:15:30 -0800

Brain cells that reflect self position relative to others have been identified in the rat hippocampus. Sometimes these representations are processed jointly by the same cells, depending on a rat's goals and actions. This discovery, from Japan's RIKEN Brain Science Institute, deepens our understanding of the hippocampus and its role as the brain's positioning system.



Organic molecule benzonitrile detected in space

Thu, 11 Jan 18 00:15:10 -0800

Scientists studying a cold molecular cloud of the Taurus region with radio telescopes have detected the presence of a particular organic molecule called benzonitrile. The finding marks the first time a specific aromatic molecule has been identified in space using radio spectroscopy.



GBT detection unlocks exploration of 'aromatic' interstellar chemistry

Thu, 11 Jan 18 00:14:10 -0800

Astronomers using the Green Bank Telescope have made the first definitive interstellar detection of benzonitrile, an intriguing organic molecule that helps to chemically link simple carbon-based molecules and truly massive ones known as polycyclic aromatic hydrocarbons. This discovery is a vital clue in a 30-year-old mystery: identifying the source of a faint infrared glow that permeates the Milky Way and other galaxies.



Emergency department program for older adults cuts hospitalizations by 33 percent

Thu, 11 Jan 18 00:00:10 -0800

Roughly one third of all older patients age 65 and older visiting emergency departments nationwide are admitted to the hospital. But an emergency department program focused on geriatric transitional care has reduced the risk of unnecessary admission of older patients at Northwestern Medicine by 33 percent, according to a new study from Northwestern Univeristy, Mount Sinai Medical Center and St. Joseph's Regional Medical Center.



Hubble finds substellar objects in the Orion Nebula

Thu, 11 Jan 18 00:16:30 -0800

Astronomers using NASA's Hubble Space Telescope have uncovered the largest known population of brown dwarfs sprinkled among newborn stars in the Orion Nebula.



NASA calculated heavy rainfall leading to California mudslides

Thu, 11 Jan 18 00:01:40 -0800

Winter rains falling on recently burned ground triggered deadly mudslides in Santa Barbara County, California on Jan. 9. NASA calculated the amount of rain fall between Jan. 8 and 10, 2018 and calculated the potential for landslides.



NASA's IMERG measures Tropical Cyclone Ava's disastrous rainfall

Wed, 10 Jan 18 00:12:00 -0800

Tropical cyclone Ava dropped extremely heavy rainfall over Madagascar as it passed over the eastern side of the island country on Jan. 5 and 6, 2018. NASA calculated how much rainfall occurred using satellite data.



Space fever: Weightlessness increases astronauts' body temperature
Astronauts float weightlessly through space, and the condition of weightlessness is something many would love to experience. However, in addition to producing both physical and psychological stress, a trip into space affects our core body temperature. Researchers from Charité - Universitätsmedizin Berlin have observed that astronauts run hot when exposed to weightlessness, and that, even at rest, their body temperature is approximately 1
