Phys.org / 'Space archaeology' reveals first dynamic history of a giant spiral galaxy
A team of astronomers led by the Center for Astrophysics | Harvard and Smithsonian have for the first time used galactic archaeology, the study of detailed chemical fingerprints in deep space, to trace the history of a galaxy ...
Phys.org / Astronomers discover 87 stellar stream candidates in the Milky Way
Stellar streams are trails of stars that astronomers can study to solve mysteries about the history of our Milky Way galaxy and, potentially, the dark matter that helps shape the cosmos despite eluding direct observation. ...
Medical Xpress / New research suggests FDA should consider redesign of proposed nutrition labels
Packaged foods offer convenience for families and individuals, but they can be a major source of saturated fat, sodium and added sugars, which when consumed in excess contribute to chronic disease. To help people build healthier ...
Medical Xpress / Short-lived fish offer new insights into the aging immune system
Our immune system protects the body from infections and harmful changes throughout our lives. However, it loses its effectiveness with age, resulting in an increased risk of disease. But what happens when the immune system ...
Phys.org / Stolen chloroplasts maintained by host-made proteins offer clues to plant cell origins
Every plant cell is the product of a biological merger billions of years ago. Chloroplasts are key structures in plants and algae that capture sunlight, but originally they were free-living bacteria that took up residence ...
Phys.org / Critically endangered monkey gives birth after surgery saves her foot
A critically endangered monkey has given birth just months after pioneering surgery saved her from undergoing an amputation. Masaya, a 15-year-old roloway monkey at Chester Zoo, had a golf-ball-sized mass removed from her ...
Medical Xpress / For the first time, scientists have mapped the genetics of how the brain ages, region by region
A landmark research paper for the first time maps the genetics of how individual regions of the brain age—and why some of those regions are the very ones most ravaged by Alzheimer's and dementia. Published in the journal ...
Medical Xpress / Scientists discover new genetic disease that causes premature aging and cognitive deficits
Scientists at Sanford Burnham Prebys Medical Discovery Institute and an international team of collaborators have defined a new genetic disease marked by premature aging and deficits in brain function. The researchers have ...
Phys.org / In flight simulators, crews with better rapport perform better, study finds
Picture a cockpit crew of two who met just minutes before takeoff, now descending through a turbulent midnight sky. They aren't looking at each other—their eyes scan the instruments in the cockpit and the horizon outside—and ...
Phys.org / Employee referrals may trigger bias: Colleagues see referred hires as less meritorious
Employee referrals can aid hiring but carry hidden downsides. New research by Rellie Derfler-Rozin at the University of Maryland's Robert H. Smith School of Business and Teodora Tomova Shakur of Texas Christian University ...
Phys.org / Researchers create a three-nanometer single-layer UiO-66 MOF nanosheet
Metal-organic frameworks (MOFs) are porous structures composed of metal ions (or clusters) and organic linker molecules—much like a molecular scaffold. Thanks to their high porosity and large surface area, MOFs can store ...
Phys.org / The 'silent takeover': Invasive bees are reshaping Chile's unique pollination networks
Biological invasions are a major driver of biodiversity loss and invasive pollinators can reshape native plant-pollinator networks. A new study published in the journal NeoBiota reveals that invasive pollinators are fundamentally ...
