Phys.org / Disabled parrot is undefeated alpha male of his group thanks to novel 'beak jousting'
A study reported in Current Biology shows how physical disabilities in the animal world can be overcome through behavioral innovation. The report features an endangered kea parrot in captivity at New Zealand's Willowbank ...
Phys.org / New bioreactor turns stem cells into an immune-cell factory, producing 40 million human macrophages per week
Researchers at Hannover Medical School (MHH) have developed a method for the efficient production of human immune cells, such as macrophages, in medium-sized bioreactors. These immune cells can be derived from induced pluripotent ...
Phys.org / When humidity changes, so do the colors of sweat bees
Nature is a riot of color. In the animal kingdom, many species, from insects to cephalopods, use their permanent color or change it for communication, camouflage, and thermoregulation. While this type of reversible shift ...
Phys.org / Cold fronts in nearby galaxy group may redistribute metals, Chandra and GMRT data reveal
Astronomers from South Africa and India have analyzed archival data from the Chandra X-ray Observatory and Giant Metrewave Radio Telescope (GMRT) regarding a nearby small galaxy group known as IC 1262. Results of the new ...
Phys.org / DNA damage just got more complicated: A long-missed weak spot emerges when light and oxygen strike
In everyday life, our genetic material is constantly under attack from many factors. Environmental influences such as light, along with internal processes like inflammation, can generate oxidative stress that damages DNA ...
Phys.org / More shearwaters are washing up dead on Australian beaches. It's not due to 'natural' causes
You might know the short-tailed shearwater and sable shearwater by the common name "muttonbirds." These two species of seabird breed on islands off southeastern Australia. Both undertake a breathtaking two-week, non-stop ...
Phys.org / Don't just plant trees, plant forests to restore biodiversity for the future
Around the world, people plan to plant more than 1 trillion trees this decade in an ambitious effort to slow climate change and reduce biodiversity loss. But if the past is prolonged, many of those planted trees won't survive. ...
Tech Xplore / Bubble trouble: Hydrogen research highlights outsized impacts of tiny bubbles in water electrolysis
Hydrogen is often described as the fuel of the future—a clean, energy-dense way to store renewable power and decarbonize industries from steelmaking to shipping. But inside the devices that produce it, a surprisingly small ...
Phys.org / Alternating atomic layers enable rare electron pairing mechanism in new unconventional superconductor
Superconductors, materials that can conduct electricity with a resistance of zero, have proved to be highly promising for the development of quantum technologies, medical imaging devices, particle accelerators and other advanced ...
Phys.org / Divergent moral values could make groups more accepting of norm-breaking behavior
Individuals in a morally diverse community tend to believe that the community's norms are looser. In turn, norm violations are more accepted, and there is a reduced willingness to police transgressions, according to research ...
Phys.org / Bonuses can lower self-set goals and reduce performance, experiment suggests
Financial bonuses are often used to motivate employees to meet targets and boost productivity. But do they actually work? New research from Tilburg University suggests these incentives can sometimes have the opposite effect. ...
Phys.org / Laser bursts flip nanoscale magnetic vortices at blistering speeds, opening a path to brain-like spintronics
Spintronics are devices that operate leveraging the spin, an intrinsic form of angular momentum, of electrons. The ability to switch magnetic states is central to the functioning of these devices, as it ultimately allows ...
