Phys.org / Could your housemates be changing your gut bacteria? An island bird study suggests so
Living with friends may quietly be altering your gut bacteria, according to a new study from the University of East Anglia. Research on a colony of tiny island birds reveals they share more of their gut bacteria with the ...
Phys.org / Rod-shaped synthetic swimmers reveal a 'sweet spot' for active turbulence
Inspired by the collective dynamics of bacteria like E. coli and Bacillus subtilis, researchers at the University of Twente asked a simple but fundamental question: what happens when artificial swimmers are made rod-shaped ...
Phys.org / Seabirds reveal global mercury distribution in oceans
Mercury released into the oceans affects marine environments worldwide. Traditionally, its distribution and quantity have been estimated using marine biogeochemical simulation models.
Phys.org / Street green space can help cool cities, but it will not be enough on its own
A new IIASA-led study finds that expanding street green space can reduce urban heat stress in cities worldwide, but even ambitious greening efforts are unlikely to offset a significant share of the additional heat expected ...
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 / 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 / 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 / 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 / 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 / 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 ...
