Phys.org / A handful of teeth may rewrite the story of marsupial evolution
Researchers have found evidence of a previously unknown branch of the marsupial family tree, a discovery that could reshape our understanding of how Australia's unique mammals evolved. Published in the Journal of Paleontology, ...
Phys.org / Pixels preserve world's rarest porpoise to 3D digital archive as extinction risk grows
The vaquita (Phocoena sinus), an elusive porpoise found only in the shallow waters of Mexico's northern Gulf of California, is one of the rarest and most endangered marine mammals on Earth. Measuring about 5 feet (1.5 meters) ...
Phys.org / Ultrafast laser pulses reveal a material's hidden state of matter
What would it take to instantly transform a material from an electrical insulator into a conductive state without ever touching it? Using ultrafast laser pulses and powerful X-rays, scientists at the National Synchrotron ...
Phys.org / Chemists reveal one-step 'alkyl swap' that rewrites key amines for drug discovery
For more than a century, chemists have been building complex molecules step by step—bond by bond, atom by atom. But what if, instead of painstakingly reassembling molecules, they could be directly "rewritten"? This is exactly ...
Phys.org / Reforestation's effects on water resources may depend on global warming level
Planting trees is widely promoted as a natural solution to climate change. But a new study led by researchers from the Institute of Atmospheric Physics at the Chinese Academy of Sciences finds that the hydrological consequences ...
Phys.org / How plants rush energy to injured tissues to help them heal
A new study finds that plants respond to injury by actively redirecting sugars to damaged tissues, helping fuel the regeneration process. Using a fluorescent sensor to track sugar movement in living plants, researchers have ...
Phys.org / New imaging technique measures single scramblase proteins, revealing lipid transport rates
A new single-protein analysis technique gives researchers an unprecedented ability to study proteins called scramblases, which have critical roles in biology. The development of the new technique, in a study led by investigators ...
Phys.org / Water-based nanoprinting moves metal films onto delicate 3D surfaces without damage
A new technology allows metal circuits floating on water to be transferred directly onto any desired surface. A South Korean research team has introduced a novel technique capable of transferring ultra-fine nanocircuits onto ...
Phys.org / Plants reveal backup system for sensing and adapting to rising temperatures
University of Mississippi researchers are studying how plants respond to heat at the molecular level, an important consideration for farmers, businesses and policymakers as global temperatures rise.
Phys.org / Only 10 viral particles cause H5N1 avian flu infection in cows
Just 10 viral particles of the H5N1 bird flu that caused hundreds of influenza outbreaks in U.S. dairy cattle can cause infection in cows, a new study shows. The research also hints at why the outbreaks have confounded scientists, ...
Phys.org / Why Arctic sea ice loss could reshape the Gulf Stream's future
The warm Gulf Stream is maintained by coldness. The Barents Sea is a cooling machine. To predict how ocean currents in the Atlantic Ocean may develop, one needs to know what drives them. The hunt for driving forces has led ...
Phys.org / Beyond frozen snapshots, protein 'breathing' comes into view with combined imaging methods
Advances in structural biology have allowed scientists to determine molecular structures with atomic-level detail, sometimes yielding static snapshots that do not reflect the dynamism of proteins. However, these motions are ...
