Phys.org / Mammal ancestors laid eggs—and this 250-million-year-old fossil proves it
A remarkable new discovery is shedding light on one of the greatest survival stories in Earth's history, and answering a decades-old scientific mystery. Lystrosaurus, a hardy, plant-eating mammal ancestor, rose to prominence ...
Phys.org / No more giants, no more heavy handaxes: Why early humans downsized their stone tools
For more than 1 million years, early humans in the Levant region of the eastern Mediterranean used a range of heavy tools, such as massive handaxes and stone balls, for important tasks, including processing animal carcasses. ...
Phys.org / What if dark matter came in two states?
The absence of a signal could itself be a signal. This is the idea behind a new study published in the Journal of Cosmology and Astroparticle Physics, which aims to redefine how we search for dark matter, showing that it ...
Phys.org / Plant-inspired water membrane filters CO₂ with constant selectivity and adjustable permeance
Gas separation membranes are vital for carbon capture, biogas upgrading, and hydrogen purification, all of which require the separation of carbon dioxide from gases like nitrogen, methane and hydrogen. However, the membranes ...
Phys.org / Oxygen sensing helps explain why amphibians regenerate limbs but mammals cannot
Some animals can regrow lost body parts. Salamanders and frog tadpoles can rebuild entire limbs after amputation. Mammals cannot. For decades, biologists have tried to understand why. Now a team led by Can Aztekin at EPFL ...
Phys.org / From Asgard to Earth: Tiny tubes may reveal the moment complex life began
Stromatolites—and their close relatives, microbial mats—could be mistaken for what seems like a bunch of old dark rocks. But instead, they are dense, layered communities of microbes. Long before complex life such as animals ...
Phys.org / AI-designed proteins built from scratch can recognize specific compounds
Professor Gyu Rie Lee of the Department of Biological Sciences successfully designed artificial proteins that selectively recognize specific compounds using AI through joint research with Professor David Baker. The research, ...
Phys.org / Why treelines don't simply rise with the climate
A global study by the University of Basel, Switzerland, reveals a surprising picture: While 42% of treelines worldwide are shifting upslope, 25% are retreating. This seemingly contradictory trend involves more than just warming. ...
Phys.org / Simple vineyard growing practice impacts soil microbiome deep below surface
Pennsylvania is the fourth-largest wine producer in the United States, according to the Pennsylvania Department of Agriculture. The industry supports nearly 11,000 jobs and directly contributes $1.77 billion to the state ...
Phys.org / Great apes mirror facial expressions with surprising precision, study shows
New research from the University of Portsmouth has found that great apes exhibit exactness in mimicking one another's facial expressions in social contexts. The study, published in Scientific Reports, explored how orangutans ...
Phys.org / Ancient Māori remains point to largely plant-based diets before colonization
New research led by the University of Otago—Ōtākou Whakaihu Waka, in close partnership with mana whenua, is shedding new light on Māori diet and burial practices in Aotearoa New Zealand prior to European colonization. The ...
Phys.org / Hidden ocean feedback loop could accelerate climate change
The world's oceans may be quietly amplifying climate change in ways scientists are only beginning to understand. In a new study published in Proceedings of the National Academy of Sciences, University of Rochester scientists—including ...
