Phys.org / Light lets microswimmers switch between bacteria-like and algae-like propulsion
Physicists at Leipzig University and Charles University in Prague have developed a method for changing the swimming style of tiny artificial microswimmers in real time. They can make a single microscopic particle switch at ...
Phys.org / Why do some chimpanzee mothers carry their dead infants for months?
Chimpanzee and bonobo mothers sometimes continue to carry their infants after they have died, a behavior known as infant corpse carrying (ICC). It is widely documented, and many explanations have been proposed, but few have ...
Phys.org / Fungi neutralize spruce defense mechanisms with sugar
A research team at the Max Planck Institute for Chemical Ecology discovered a previously unknown strategy by which certain fungi neutralize spruce defense compounds. These fungi are introduced into trees by bark beetles, ...
Phys.org / Weeping whales: Stillborn humpback whale grieving documented
Humpback whale mothers may experience grief when their calves die, a rare research observation led by Griffith University and Sea World Foundation has found.
Phys.org / Hot electrons reveal electronic collisions may raise resistance in twisted graphene
When a material heats up, its electrical resistance often rises. The harder question is what, exactly, is getting in the way. The electrons carrying the current may be scattered by vibrations of the material's atomic lattice, ...
Phys.org / Without bacteria or chemicals: How methanol and formaldehyde form abiotically in nature
The biopolymer lignin—one of the most important carbon reservoirs in plants and soils—not only decays through fungi or bacteria but can also be chemically attacked by iron linked to reactive oxygen species, without the involvement ...
Phys.org / Muon rings enable precise calibration of telescopes at the Cherenkov Telescope Array Observatory
Research initiated as part of a bachelor's thesis in physics at the Universitat Autònoma de Barcelona (UAB) has culminated in a new analytical description of the muon-based calibration of dual-mirror Cherenkov telescopes. ...
Phys.org / We may soon be able to read long-lost ancient scrolls damaged by the eruption of Mount Vesuvius
X-ray technology and artificial intelligence—along with the discovery of lead in the ink of fragments from a collection of ancient Roman scrolls—could soon help scientists read long-lost texts buried by the eruption of Mount ...
Phys.org / Building big with DNA gets a software upgrade
Forty-four years ago, Nadrian Seeman published his groundbreaking ideas on using DNA as a structural material, expanding DNA's significance far beyond its role as a carrier of genetic information. Since then, the steadily ...
Phys.org / Bone strength study reveals new clues about human evolution
Bipedalism, or walking on two legs, is one of the key features that distinguishes humans from other apes. But when and why our ancestors transitioned from a life often spent in trees to a life spent almost exclusively on ...
Phys.org / Aqueduct deposits suggest Plague of Cyprian may have emptied Nîmes around 270 A.D.
Researchers at Johannes Gutenberg University Mainz (JGU) have gleaned new insights into ancient water management in the French region around Nîmes by analyzing carbonate deposits within the Roman aqueduct that features the ...
Phys.org / Dogs show human-like brain activity when they restrain themselves
When we tell a dog "no" and it resists temptation, what happens in its brain? New research from the Department of Ethology at ELTE and the HUN-REN Research Centre of Natural Sciences suggests that dogs may do more than respond ...
