Phys.org / Insights into bee biology could ease US rules for organic honey
Strict regulations have prevented continental U.S. beekeepers from participating in the lucrative organic honey market, but new research finds that bees' actual habits make certain rules too extreme. The findings potentially ...
Phys.org / New immune-blocking strategy improves interspecies organ generation
Xenophagocytosis is a natural immune process that limits interspecies organ generation by eliminating living donor cells, researchers at the Institute of Science Tokyo, Japan, report. By uncovering how embryonic macrophages ...
Phys.org / Deadly blooms offer a genetic blueprint for making hard-to-synthesize medicinal compounds
Two plants that cause neurotoxicity and paralysis in the tiniest doses are also known to counter pain, malaria, cancer and pests. For the first time, researchers discovered a way to recreate these powerful compounds in the ...
Phys.org / Electron cooling tames highly charged ions in Penning trap for first time
Researchers at Technical University of Darmstadt and the GSI Helmholtz Center for Heavy Ion Research have succeeded for the first time in decelerating highly charged ions from the GSI accelerator to low energies and subsequently ...
Phys.org / Oil droplets remodel themselves, swallow their surroundings like living cells
NYU researchers have made microscopic oil droplets in water do something usually reserved for living cells: change shape in complex, controllable ways and even engulf their surroundings.
Phys.org / How molecular tethers and asynchronous replication drive parasite proliferation
Malaria parasites proliferate in an unusual way. Rather than dividing into two daughter cells like human cells, they first amplify their genetic material tenfold, hundredfold or even thousandfold before simultaneously producing ...
Phys.org / Solar wind stirs Mars' upper atmosphere, boosting ion loss to space
Our sun constantly releases a stream of high-speed charged particles, known as the solar wind. Unlike Earth, Mars does not have a strong global magnetic field to shield its atmosphere from this flow. As a result, the solar ...
Phys.org / Ancient diamond preserves evidence of water-bearing mineral deep in Earth's mantle
A team of Brazilian researchers discovered the first direct evidence that goethite—the mineral responsible for the brown color of soils—can withstand extreme pressures and temperatures all the way to the planet's interior ...
Phys.org / Astronomers finally measure the full size of the largest known galaxy
Researchers have obtained the deepest images ever taken of IC 1101, allowing them to identify the galaxy's outer edge for the first time. The observations confirm it as the largest known galaxy, spanning roughly 520 kiloparsecs, ...
Phys.org / Experts survey the glacier ice on Mount Ararat for the first time
Facing wind and cold, with only half as much oxygen to breathe as in the valley, a German-Turkish research team surveyed the glacier on Mount Ararat in eastern Turkey for the first time in July, at more than 5,000 meters ...
Phys.org / Diego Rivera claimed his mural Creation was half wax, but chemical forensics says otherwise
Adorning the walls of San Ildefonso College in Mexico City is artist Diego Rivera's masterpiece, rendered in fresco and gold leaf, The Creation, or La Creacioń. It depicts a man standing with his arms outstretched beneath ...
Phys.org / Lichen-like life 600 million years ago may push back origins of fungal-algal partnerships
Two organisms inhabiting a common environment can sometimes mutually influence each other, either benefiting or, in some cases, damaging one another. This mutually beneficial or ambivalent biological relationship is known ...
