Phys.org / Lost megalodon vertebrae resurface, confirming 80-foot size estimate
An associated set of gigantic vertebrae belonging to the iconic extinct megalodon, or megatooth shark, that had been missing in action since the 1980s was discovered, providing new information about the shark's lifestyle. ...
Phys.org / The oldest evidence of mourning rituals reveals Paleolithic communities grieved like we do
Roughly 27,500 years ago, a 15-year-old boy was brutally mauled by a bear in Arene Candide in what is now Liguria, Italy. The attack tore through his jaw, neck and left shoulder. He was dying, but he was not alone in his ...
Medical Xpress / Bones communicate with the rest of the body to support overall health: Here's the science behind your skeleton
Each year, doctors treat more than 6 million bone fractures in the United States. And while it takes only a few seconds for a bone to break, the processes that keep your bones strong and allow them to heal take place continuously ...
Phys.org / Human activity has driven retreat of Antarctica's fastest melting glacier
Human-driven climate change significantly intensified the retreat of one of the most important glaciers in Antarctica during the 20th century. The Pine Island Glacier, which drains a large part of the West Antarctic Ice Sheet ...
Phys.org / Reanalysis suggests 'Phoebe' is a variable star, not a primordial black hole
A new study debunks a recent claim that astronomers may have detected a lunar-mass primordial black hole. In a reanalysis of observations from the Dark Energy Camera (DECam), researchers found that the star nicknamed "Phoebe" ...
Phys.org / Shining blue light on gold-graphene nanodots achieves wound healing trifecta
Closing wounds, burns and deep cuts isn't enough to kick-start healing. A wound needs a clean environment, free of bacterial infection and interruption. That calls for three components working together—one to kill bacteria, ...
Phys.org / Nanopattern method unlocks precise control of disorder for wave-guiding devices
A research team has developed a methodology to precisely design and control the "degree of disorder" in nanopattern arrays using metal-infiltrated block copolymer (BCP) thin films. The work was led by Professor So Youn Kim ...
Phys.org / Injectable silk-kudzu hydrogel achieves complete wound closure in laboratory tests
Researchers at the Terasaki Institute for Biomedical Innovation have developed an injectable hydrogel, a water-based gel material, made from silk proteins and a plant-derived compound. In laboratory tests, the material promoted ...
Phys.org / Off-center stellar death points to wandering supermassive black hole stripped of its own galaxy
Astronomers have uncovered new details about the black hole that ripped apart a star in a tidal disruption event named AT2024tvd. Findings suggest it is a wandering supermassive black hole—the kind that is not located at ...
Medical Xpress / Scientists uncover how ovarian cancer resists chemotherapy—and how to reverse it
Michigan State University researchers have identified how ovarian cancer cells become resistant to chemotherapy and discovered a protein that, when blocked, can restore the drug's effectiveness.
Medical Xpress / Neural pathways reveal a push-pull system for coordinating goal-directed behavior in mice
Most of the tasks that humans complete daily entail carefully coordinating movements and tracking progress made toward a desired goal. Past studies have highlighted the role of the basal ganglia (BG), a set of interconnected ...
Phys.org / Bird flu is deadly for backyard chickens—and even cats. A vet expert explains
The deadly H5N1 strain of bird flu has been found in seabirds in two Australian states.
