Birds have a lot to do in their short lives: defend territories, build nests, raise chicks and feed themselves. But the toll of these activities may be greater for female birds than for male birds. A new study by UCLA ornithologists has found that female birds have lower
Every embryo of an organism that reproduces sexually faces an early and consequential decision: which of its cell lineages will make up the mortal body, and which will become the germline, the lineage that eventually makes eggs or sperm and carries genetic information to the
When a virus enters a cell, its top priority is to replicate its genome rapidly, creating new viruses to infect elsewhere. The host has the opposite priority: to destroy the virus, ideally before it can do any harm. Biology has evolved diverse tactics for viral recognition and
What if glowing molecules could synchronize, much like fireflies flashing in unison? Researchers have discovered that molecules confined within tiny gold nanostructures can behave collectively, coordinating their interactions even under conditions where this was previously
Hundreds of Turkish firefighters on Thursday battled to contain wildfires spreading near key tourist regions on the country's Mediterranean coast.
Poxviruses have a long history in human disease as well as medicine: The first-ever vaccine was developed to protect against smallpox, which has since been eradicated. Despite this, scientists still don't fully understand how poxviruses infect and replicate inside our cells.
Summer days featuring conditions that promote wildfire ignition, intensity and spread have more than doubled across large parts of the Iberian Peninsula, France, Italy and Greece since 1981, according to a study in Scientific Reports. The findings suggest that hotter, drier

Southern Europe is "becoming more flammable," with the number of summer days primed for extreme fire conditions more than doubling since 1981, a new study found Thursday.
Quantum fluctuations influence direction-dependent electrical transport in chiral magnets, researchers from Science Tokyo report. In chiral magnetic systems, electric current flows differently depending on its direction, but the role of quantum effects in this behavior has
For centuries, artisanal and industrial activities have left many soils polluted with excessive levels of heavy metals such as zinc, cadmium, copper and lead, posing a threat to the environment and human health. Cleaning up polluted sites is often difficult and expensive,
When catastrophic wildfires capture global headlines, such as the unprecedented blazes sweeping through southern Europe this summer or the devastating 2019–20 "Black Summer" in Australia, they are almost always preceded by severe drought. Dry vegetation and parched landscapes
Algae are increasingly being explored as sustainable "living factories" that can convert sunlight and carbon dioxide into renewable fuels, plastics, pharmaceuticals and other valuable products.
Pharmaceutical drugs often rely on chemical compounds found in the body. Take phosphate, a common compound cells use as a chemical switch. In a process called phosphorylation, cells can add a phosphate to a molecule and turn its function on. When the function is no longer
Italian authorities raised the drought alert level to "high" Thursday in the Po Valley, home to the country's longest river, because of worsening conditions and unfavorable weather forecasts.
Researchers have developed and tested an infrared spectroscopy system that can rapidly detect chemical aerosols from a distance by using light reflected from common surfaces such as traffic signs, tree trunks or painted surfaces. The new method could make it possible to detect
University of Maryland researchers discovered a new approach to treating venomous snakebites—using the same toxin-blocking proteins that snakes evolved to protect themselves. The team found that specific combinations of blood proteins from western diamondback rattlesnakes
Greece on Thursday battled to contain a spate of wildfires, including one on the tourist island of Crete that forced thousands of residents and holidaymakers to evacuate and left three firefighters dead.
Large-scale quantum communication networks require both reliable quantum memories and coherent single-photon sources that can exchange quantum information efficiently. A coherent source of single photons with narrow linewidth, high brightness, spectral uniformity and
