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 / Chandra reveals flickering supernova remnants in M83 over 14 years

The aftermath of a supernova, a stellar explosion, is usually a slowly fading cloud of hot gas. So when astronomers pointed NASA's Chandra X-ray Observatory at the nearby galaxy Messier 83 (M83), they did not expect to find ...

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 / Deep Earth model traces 270 million years of seamount formation across oceans

Over 40,000 seamounts—undersea mountains that don't breach the ocean's surface—are scattered across the ocean floor. Some form linear chains, while others occur as dispersed, isolated features that are not part of well-defined ...

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 / A star's death throes involve a lot of kicking

When stars like our sun age, they puff up into red giants. Their bubbling outer mass gradually escapes into space, and their remaining cores contract into white dwarfs. Since most stars end their lives this way, the universe ...

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 / 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 / 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 / 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 / ALMA makes first direct detection of star-forming gas in early galaxies

In the early universe, the first galaxies began to take shape roughly a million years after the Big Bang. Within these young systems, stars formed from vast reservoirs of cold gas, gradually building the structures we see ...

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 ...
