Phys.org / Back to the beach: Why did evolution return some animals to the water?
In most narratives, the story of evolution is the story of organisms emerging from the ocean and eventually populating the land. But for some species, that evolution also involved a return trip. Dozens of major mammal and ...
Phys.org / Why mysterious structures within Earth's mantle hold clues to life here
For decades, scientists have been baffled by two enormous, enigmatic structures buried deep inside Earth with features so vast and unusual that they defy conventional models of planetary evolution.
Medical Xpress / Microglia modulate the reactivity of astrocytes in Alzheimer's disease, study finds
Alzheimer's disease (AD) is a highly debilitating neurodegenerative disease characterized by the progressive loss of memory and decline of mental functions. Earlier research has uncovered some of the neural and biological ...
Phys.org / Over a decade in the making: Lanthanide nanocrystals illuminate new possibilities
In a discovery shaped by more than a decade of steady, incremental effort rather than a dramatic breakthrough, scientists from the National University of Singapore (NUS) and their collaborators demonstrated that great ideas ...
Tech Xplore / Machine learning algorithm rapidly reconstructs 3D images from X-ray data
Soon, researchers may be able to create movies of their favorite protein or virus better and faster than ever before. Researchers at the Department of Energy's SLAC National Accelerator Laboratory have pioneered a new machine ...
Phys.org / Study maps the time and energy patterns of electron pairs in ultrafast pulses
The ability to precisely study and manipulate electrons in electron microscopes could open new possibilities for the development of both ultrafast imaging techniques and quantum technologies.
Phys.org / Airborne sensors map ammonia plumes in California's Imperial Valley
A recent study led by scientists at NASA's Jet Propulsion Laboratory in Southern California and the nonprofit Aerospace Corporation shows how high-resolution maps of ground-level ammonia plumes can be generated with airborne ...
Phys.org / Video catches wild wolf pulling in crab trap to get to food—but is it tool use?
Many animals have been observed using tools. For example, chimps tear leaves off of branches and stick them into holes to pull out termites, and wild dingoes have been observed moving objects to stand on to get to another ...
Medical Xpress / Why a foreign language sounds like a blur to non-native ears
Why is it so easy to hear individual words in your native language, but in a foreign language they run together in one long stream of sound?
Phys.org / Y1 is an ultra-luminous infrared galaxy, ALMA observations reveal
Using the Atacama Large Millimeter/submillimeter Array (ALMA), an international team of astronomers has inspected a distant galaxy designated MACS0416_Y1. Results of the observations, presented Nov. 11 on the arXiv pre-print ...
Medical Xpress / Cancer cells have backup metabolic pathway to keep building DNA when blocked, study finds
Northwestern Medicine scientists have uncovered a surprising link between a tiny cellular engine and the way cancer cells build the DNA they need to proliferate, according to a new study published in Molecular Cell.
Medical Xpress / Daily pill helps people lose 10% of weight in 18 months, study finds
A daily pill that is cheaper and easier to take than currently available weight loss drugs helps people lose around a tenth of their body weight over nearly 18 months, a study said Thursday.
