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 final moments.
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. Two Museum of Southern Jutland staff members, Mette Elstrup and Trine Sørensen, and a researcher at Aarhus University, Henrik Lauridsen, teamed up with a scientist in the United States and another in Australia and took a renewed look at a once-lost vertebral specimen of Otodus megalodon, the fossil shark that lived nearly worldwide about 15 million to 3.6 million years ago.
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 into the Amundsen Sea, is one of the biggest contributors to global sea level rise.
The deadly H5N1 strain of bird flu has been found in seabirds in two Australian states.
It feels like every few months we get to report on another academic paper singing the praises of the Solar Gravitational Lens (SGL). Partly, this is due to Dr. Slava Turyshev's astounding productivity in pumping out academic articles, but partly because such a groundbreaking mission has lots of positive aspects—as well as challenges that need to be addressed. A new paper, posted to the arXiv preprint server from Dr. Turyshev, stresses an often overlooked feature of the SGL: how useful it can be for imaging things other than faraway exoplanets.
Europe's deadly heat wave pushed east Sunday, with hundreds of millions still sweltering across the continent despite fleeting relief from overnight storms, notably in France and Belgium.
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 of the Seoul National University College of Engineering Department of Chemical and Biological Engineering, in collaboration with Professor Su-Mi Hur's team at DGIST and Professor S. Joon Kwon's team at Sungkyunkwan University. The paper is published in the journal Nature Communications. The study was selected as an Editors' Highlight in materials science and chemistry.
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 complete wound closure within 72 hours, suggesting a potential new approach to minimally invasive soft tissue repair.
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" was simply doing something ordinary that many stars do: changing its brightness naturally over time. The new findings have been reported in a paper posted to the arXiv preprint server on June 17.
One year ago, on July 1, 2025, astronomers discovered a fascinating new object moving through the solar system. Detected by the Asteroid Terrestrial-impact Last Alert System (ATLAS), the object was quickly recognized as something special.
