Phys.org / Rewilding could fill gap left by Panama's lost giants
Many large herbivores that once roamed modern-day Panama have declined or died out—including the 6-meter-long giant ground sloth and elephant-related creatures called Cuvieronius. New research suggests that introducing ...
Phys.org / Metasurface-based SLM could enhance AR, VR and LiDAR performance
Many cutting-edge technologies, ranging from augmented reality (AR) and virtual reality (VR) to LiDAR (light detection and ranging) systems, rely on components that enable the precise control of light. These components include ...
Phys.org / Late scientist's notebooks help finish study of rare 55-million-year-old tarpon fossil
Recently-revealed notebooks belonging to a late paleontologist contain the missing information needed to help researchers finish their study of a remarkable fossil discovered nearly three decades ago.
Phys.org / Discovery of natural mechanism behind ferroptosis solves longstanding puzzle in cell biology
After more than a decade of research, scientists have discovered the natural mechanism behind a novel form of cell death called ferroptosis. The work, described in the current issue of Cell, points toward an entirely new ...
Phys.org / Studying snakes' ability to stand upright could inform soft robotics and more
Snakes may be best known for slithering. But consider that these animals also perform one of the most extreme feats of posture control found in nature: They can stand nearly straight upright on a narrow perch without falling, ...
Phys.org / Brain structure volume linked to increased social tolerance in macaques
Researchers have found that the size of the amygdala—a region of the brain involved in processing emotions—could be linked to social tolerance in macaque monkeys. Their research, published today in eLife, is described ...
Phys.org / Newfound third cell type enables fully functional hair follicles in the lab
Hair regrowth treatment may soon take a major leap forward, as researchers in a recent study have successfully grown complete, fully functional hair follicles outside of the living body, in a dish. This was made possible ...
Phys.org / NASA's MAVEN detects first evidence of lightning-like activity on Mars
While sifting through the extensive data collected by NASA's Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft over the last decade, scientists discovered a familiar type of electromagnetic signal commonly caused ...
Phys.org / Newly excavated Maya wetland settlement shows the civilization's adaptation to changing climate
Past civilizations have been significantly affected by climate change, but how they adapted to new conditions centuries ago is less clear. In research newly published in the Proceedings of the National Academy of Sciences, ...
Phys.org / Greenland's largest glacier could soon reach a tipping point, scientists say
Greenland's largest glacier, Jakobshavn Glacier, may be edging closer to a critical threshold as meltwater runoff from the Greenland Ice Sheet accelerates in ways not seen in over a century, according to new research published ...
Phys.org / Poking a nanostring: Scientists uncover energy cascades in tiny resonators
Scientists at TU Delft have designed a nanostring that, when poked, doesn't lose its energy to the environment immediately. Instead, the energy leaks out within the string, triggering a cascade of distinct vibrational modes. ...
Phys.org / Tiny Purgatorius fossils in Denver Basin hint at early primate spread southward
New minuscule fossils of Purgatorius, the earliest-known relative of all primates—including humans—have been unearthed in a more southern region of North America than ever before, and the breakthrough is providing paleontologists ...
