Phys.org / SoCal's hybrid bees outsmart Varroa mites before they even hatch
Southern California is home to a flying black-and-yellow treasure. While commercial honeybee hives nationwide are collapsing under attack from deadly parasites, a unique hybrid bee found only in this part of the state has ...
Phys.org / Camera-tagged Adélie penguins caught eating sea snails in East Antarctica
There are many poorly understood links in the food web, often referred to as trophic relationships. Out in East Antarctica, a previously unconfirmed link between sea snails and Adélie penguins might reveal more than meets ...
Phys.org / Nicotine's last biosynthesis steps mapped in wild tobacco, ending a long mystery
Nicotine, a potent insecticidal alkaloid unique to the nightshade family, has been employed in agriculture as a pesticide since 1690. It also has therapeutic potential for neurological disorders such as Alzheimer's disease, ...
Phys.org / Underwater architects: Nest-building in cichlids reveals more than hardwired instinct
We associate nests with shelter, warmth, and a safe retreat—and usually picture a bird's nest made out of twigs, grass and feathers. Yet many other animals take advantage of such refuges, with nests being built by a diversity ...
Phys.org / Subaru Telescope sheds light on Jupiter Trojan asteroids' color mystery
Observations conducted with the Subaru Telescope and its first-generation wide-field camera, Suprime-Cam, have revealed new insights into the relationship between the color and size of Jupiter Trojan asteroids.
Phys.org / Chang'e mission samples reveal how exogenous organic matter evolves on the moon
Elements essential to life, such as carbon, nitrogen, oxygen, phosphorus, and sulfur, were "delivered" to Earth and the moon during the early stages of the solar system via asteroids and comets impacting their surfaces. These ...
Phys.org / Highway widening may be heating cities faster; here's what could curb it
U.S. cities are rapidly becoming urban heat islands, where these cities are significantly warmer than their surrounding area. Vast expanses of asphalt and concrete trap heat, while large, densely packed buildings disrupt ...
Phys.org / Tropical trees are more neighborly than trees further from the equator, study finds
Tropical trees are better neighbors than trees in temperate forests, according to a study published in the journal Nature by researchers from 29 different institutions including the Smithsonian Tropical Research Institute ...
Phys.org / Rare Roman paint 'recipe' uncovered in Cartagena murals makes smart use of costly cinnabar
Roman painters commissioned at the end of the 1st century to decorate the walls of the Domus of Salvius in present-day Cartagena could hardly have imagined that their technical expertise would still attract attention twenty ...
Phys.org / Scientists discover f-block metals yield new oxygen-binding chemistry
Iron and oxygen bind together throughout the body. Most famously, iron binds dioxygen, or two oxygens paired with each other, in hemoglobin that transports oxygen through blood. But iron-oxo compounds, as they're called, ...
Phys.org / AI chips could get faster with 30-nanometer embedded memory that cuts data shuttling
When we watch videos or ask AI questions, enormous amounts of data are constantly moving inside computers. In particular, data centers that support AI must process and transfer vast amounts of data at very high speeds. However, ...
Phys.org / Bacteria from bumblebees can produce vitamin B₂ in soya drinks
Researchers at DTU have developed a new method that can reduce the time needed to find new bacteria for fermentation. They have now identified a bacterium that can be used both for acidification and to increase the vitamin ...
