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 / Tarantulas may use learning and memory to search for food and locate their retreats
Researchers have documented several cases of spatial orientation in tarantulas living both in trees and in underground burrows. Spatial orientation refers to the ability of an animal to understand where it is in three-dimensional ...
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 / 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 / After reaching speeds of 10,657 meters per second, Artemis II hurtles home for make-or-break splashdown
The Artemis II astronauts conducted a historic lunar flyby, gathered invaluable data and took in unprecedented moon views, but one of the most crucial moments of their 10-day mission is still to come: Friday's splashdown.
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 / 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 / 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 / Medieval Japanese poetry and buried trees help elucidate volatile space weather
On Earth, extreme solar activity often appears as beautiful, benign auroras. But venturing beyond the safety of the Earth's magnetic field, one faces the full brunt of a temperamental star that can suddenly erupt with flares ...
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 ...
