Astronomy & Space news

	Astronomers baffled by discovery of rare quasar quartet Using the W. M. Keck Observatory in Hawaii, a group of astronomers led by Joseph Hennawi of the Max Planck Institute for Astronomy have discovered the first quadruple quasar: four rare active black holes situated in close proximity to one another. The quartet resides in one of the most massive structures ever discovered in the distant universe, and is surrounded by a giant nebula of cool dense gas. Because the discovery comes with one-in-ten-million odds, perhaps cosmologists need to rethink their models of quasar evolution and the formation of the most massive cosmic structures. The results are being published in the May 15, 2015 edition of the journal Science.
	Magnetar near supermassive black hole delivers surprises In 2013, astronomers announced they had discovered a magnetar exceptionally close to the supermassive black hole at the center of the Milky Way using a suite of space-borne telescopes including NASA's Chandra X-ray Observatory.
	Scientists discover the fluffiest galaxies An international team of researchers led by Pieter van Dokkum at Yale University have used the W. M. Keck Observatory to confirm the existence of the most diffuse class of galaxies known in the universe. These "fluffiest galaxies" are nearly as wide as our own Milky Way galaxy – about 60,000 light years – yet harbor only one percent as many stars. The findings were recently published in the Astrophysical Journal Letters.
	Mystery methane on Mars: The saga continues Is the Red Planet giving off methane? The question has taunted scientists for nearly 50 years, ever since the Mariner 7 spacecraft detected a whiff of the gas near Mars' south pole. Researchers retracted the finding a month later after realizing that the signal was in fact coming from carbon dioxide ice.
	OPALS boosts space-to-ground optical communications research Ever wonder why stars seem to twinkle? This effect is caused by variations in the density of our atmosphere that cause blurring in light coming from space. It's pretty for stargazing, but a challenge for space-to-ground communications.
	Video: Kepler observes Neptune dance with its moons NASA's Kepler spacecraft, known for its planet-hunting prowess of other stars, is also studying solar system objects. In its new K2 mission, Neptune and two of its moons, Triton and Nereid, have been imaged. The movie illustrates 70 days of uninterrupted observation making this one of the longer continuous studies of an outer solar system object.
	Could we live on Jupiter? NASA and Elon Musk have plans to get your ass to Mars.
	Extremely young stellar clump in the distant universe As part of an observing program carried out with the Subaru Telescope and the Hubble Space Telescope, a group of researchers from the Service d'Astrophysique- Laboratoire AIM of CEA-IRFU led by Anita Zanella discovered the birth cry of a massive star-forming clump in the disk of a very distant galaxy. This giant clump is less than 10 million years old, and it is the very first time that such a young star-forming region is observed in the distant universe. This discovery sheds new light on how stars were born within distant galaxies. The physical properties of this object reveal that newly-born clumps in such galaxies survive from stellar winds and supernovae feedback, and can thus live for a few hundred million years unlike the predictions from several theoretical models. Their long lifetime could enable their migration toward the inner regions of the galaxy, hence contributing to the total mass of the galactic bulge and the growt! h of the central black hole.

	Microsoft Hyperlapse turns long video into distilled entertainment Many can remember invitations from neighbors to view hours—and one hour could seem like hours—of footage of a family vacation, which would not be at all entertaining. It's still in many cases tedious to view unedited videos. The great thing about professional videos is that they deliver a smooth encapsulation of time that begins with a story intro leading into a "and then what happened" which flows into an ending. Microsoft Research has been working up technology that can do the same for everyone, pro or amateur. It can turn an otherwise tedious video – from a bumpy bicycle ride to a walk along a river—into a short, distilled version. On Thursday, Microsoft announced Microsoft Hyperlapse, which makes first-person videos not only fast but smooth.

They have published their results on their own website, and claim also that they have used Sohlberg and Mateer's model of attention, which allows for providing a timed result. As part of their study, they note that there are three types of human attention: sustained (prolonged focus), selective (maintaining focus despite distractions) and alternating (shifting attention between tasks or stimuli). The study consisted of surveying 200 people and administering EEG scans to 112 volunteers.
	Soft-tissue engineering for hard-working cartilage An international study published in the journal Nature Communications points the way toward wider, more effective use of biocompatible materials in repairing human tissues. Focusing on the difficult case of restoring cartilage, which requires both flexibility and mechanical strength, the researchers investigated a new combination of 3-D printed microfiber scaffolding and hydrogels. The composites they tested showed elasticity and stiffness comparable to knee-joint tissue, as well as the ability to support the growth and cross-linking of human cartilage cells. Researchers at the Technische Universität München (TUM) expect the new approach to have an impact on other areas of soft-tissue engineering research, including breast reconstruction and heart tissue engineering.

	It's best to make friends of friends—even the spotted hyena knows that Bonding with a friend of a friend is something most humans gravitate toward naturally, or at least Facebook likes to think so every time it suggests friends for you to "friend."
Phage spread antibiotic resistance Investigators found that nearly half of the 50 chicken meat samples purchased from supermarkets, street markets, and butchers in Austria contained viruses that are capable of transferring antibiotic resistance genes from one bacterium to another—or from one species to another. "Our work suggests that such transfer could spread antibiotic resistance in environments such as food production units and hospitals and clinics," said corresponding author Friederike Hilbert, DVM. The research is published ahead of print May 1, in Applied and Environmental Microbiology.
Maine, packed with moose, didn't have so many ticks Maine's state animal—the moose—fared better with potentially deadly ticks this past winter than in previous years, but the herd remains imperiled by the parasites in northern New England and beyond, wildlife biologists said.
Species in the Spotlight campaign highlights NOAA Fisheries' endangered species conservation efforts NOAA Fisheries announced today a new Species in the Spotlight campaign to focus recovery and public education efforts on eight marine species that are at risk of extinction.
	16 new lettuce breeding lines from ARS U.S. Department of Agriculture (USDA) scientists in California have developed 16 new lettuce breeding lines. Lettuce production in the United States is concentrated mostly in California and Arizona, where it is grown year-round. Salinas, California, in fact, is often referred to as "the salad bowl of the nation."
	Using ozone to protect papaya exports Postharvest diseases reduce the value and quality of agricultural products, leading to economic losses for growers and producers. This is a major issue for agricultural countries like Malaysia, which exports papaya. Current technologies such as synthetic fungicides help minimise these losses, although potential risks to human health and the ecosystem restrict the use of such chemicals.
	Cambodia border crossing and road threaten one of Asia's last great wilderness areas Some of the world's most endangered species will be driven closer to extinction if a new road and border crossing with Vietnam are built within Cambodia's pristine Mondulkiri Protected Forest – one of the most biologically diverse areas in Southeast Asia.
	Integrating and visualizing primary biodiversity data from prospective and legacy taxonomic literature XML markup of taxonomic research and specimen data is a valuable tool for structuring the incessantly accumulating biodiversity knowledge. It allows for the opportunity to collectively use the currently fragmented information for more detailed analysis.
