New research shows quasars slowed star formation
Research led by Johns Hopkins University scientists has found new persuasive evidence that could help solve a longstanding mystery in astrophysics: why did the pace of star formation in the universe slow down some 11 billion years ago?

A new way to determine the age of stars?
Researchers have developed a new conceptual framework for understanding how stars similar to our Sun evolve. Their framework helps explain how the rotation of stars, their emission of x-rays, and the intensity of their stellar winds vary with time. According to first author Eric Blackman, professor of physics and astronomy at the University of Rochester, the work could also 'ultimately help to determine the age of stars more precisely than is currently possible.'

DNA molecules directly interact with each other based on sequence, study finds
Proteins play a large role in DNA regulation, but a new study finds that DNA molecules directly interact with one another in a way that's dependent on the sequence of the DNA and epigenetic factors. This could have implications for how DNA is organized in the cell and even how genes are regulated in different cell types, the researchers say.

UMass Amherst astronomers report most 'outrageously' luminous galaxies ever observed
Astronomers at the University of Massachusetts Amherst report that they have observed the most luminous galaxies ever seen in the Universe, objects so bright that established descriptors such as 'ultra-' and 'hyper-luminous' used to describe previously brightest known galaxies don't even come close. Lead author and undergraduate Kevin Harrington says, 'We've taken to calling them 'outrageously luminous' among ourselves, because there is no scientific term to apply.'

Discovery of extinct bat doubles diversity of native Hawaiian land mammals
The Hawaiian Islands have long been thought to support just one endemic land mammal in the archipelago's brief geologic history, the Hawaiian hoary bat. But new fossil evidence indicates that a second, very different species of bat lived alongside the hoary bat for thousands of years before going extinct shortly after humans arrived on the islands. The research describes the mysterious bat, whose remains were first discovered in a lava tube more than 30 years ago.

Record-breaking ultraviolet winds discovered near black hole
The fastest winds at ultraviolet wavelengths have been discovered near a supermassive black hole. The winds have speeds of more than 200 million miles an hour, equivalent to a category 77 hurricane. The research team's discovery of the fastest ultraviolet winds ever confirmed from a quasar -- the disk of hot gas that surrounds the black hole -- is published in the 21 March 2016 print issue of the Monthly Notices of the Royal Astronomical Society.

Production of butter from shea trees in West Africa pushed back 1,000 years
University of Oregon anthropologists have pushed back the history of harvesting shea trees in West Africa by more than 1,000 years earlier than previously believed. Oil from the trees' nuts is used for cooking by local populations and exported for use such things as skin moisturizers and soap.

Video: Morphing metal shapes future of soft robotics
Cornell University engineering professor Rob Shepherd and his group have created a hybrid material featuring stiff metal and soft, porous rubber foam that combines the best properties of both -- stiffness when it's called for, and elasticity when a change of shape is required. The material also has the ability to self-heal following damage.

York University astrophysicists detect ultra-fast winds near supermassive black hole
Researchers have found the fastest winds ever seen at ultraviolet wavelengths near a supermassive black hole. Some are reaching as fast as 200 million kilometers, equivalent to a category 77 hurricane, says Jesse Rogerson of Toronto's York University who led the research. And there may be even faster quasar winds. As matter spirals toward a black hole, some is blown away. These are the winds that we are detecting, says York U Professor Patrick Hall.

Technicolor zebrafish reveal how skin heals
Every cell on the surface of a transgenic 'Skinbow' zebrafish is genetically programmed to glow with a slightly different hue. But this fish wasn't bred to brighten up an aquarium; the colors effectively stamp each cell with a permanent barcode, letting scientists track its movements in a live animal for weeks at a time. The system is a powerful new tool for visualizing how hundreds of individual cells work together to regenerate skin tissue.

Human carbon release rate is unprecedented in the past 66 million years of Earth's history
New research published today in Nature Geoscience by Richard Zeebe, professor at the University of Hawai'i - Mānoa School of Ocean and Earth Science and Technology (SOEST), and colleagues looks at changes of Earth's temperature and atmospheric carbon dioxide (CO2) since the end of the age of the dinosaurs. Their findings suggest humans are releasing carbon about 10 times faster than during any event in the past 66 million years.
