Phys.org / Prescribed fires can cut smoke pollution for years, miles beyond burn areas
A new study finds that burning 500,000 acres (202,000 hectares) of California conifer forests each year with prescribed fire could cut deadly pollution from wildfire smoke by roughly 10% over a decade.
Phys.org / Overlooked pollutants are responsible for about 15% of current global warming, study shows
In a new paper published in Science, leading scientists and climate policy experts show that 15% of current global warming (0.3°C) from human emissions stems from pollutants that fall outside most existing climate policy ...
Phys.org / Record heat pushes human-driven warming to 1.39C, 1.5C could arrive by 2030
Planetary heating is intensifying and key climate indicators are deteriorating, top scientists said Thursday, warning that funding decisions affecting Earth observation systems in the United States and other countries threaten ...
Phys.org / Newly synthesized fullerene material remains metallic even under low temperatures
An international team whose research was coordinated by Osaka Metropolitan University (OMU) has reported the survival of metallic behavior in the strongly correlated molecular material ytterbium cesium fulleride (Yb₂CsC₆₀). ...
Phys.org / Forest gaps and deadwood boost bird and bat diversity in woodlands
Disorder brings more life to the forest: Birds and bats react to this in different ways. This is shown by a new study from the University of Würzburg's Biocenter.
Dialog / Binary asteroids' puzzling configurations may link to multi-satellite history
Binary asteroid systems are widespread throughout our inner solar system. For decades, the standard paradigm held that many of them form when a rapidly spinning primary asteroid casts off material, which then reaccumulates ...
Phys.org / Parents' heat warning songs may prime zebra finch chicks for heat before they hatch
Sealed within an eggshell, how can chicks prepare for the world into which they are about to hatch, with no obvious direct communication channel across the shell? Adult zebra finches produce distinctive high-pitched warning ...
Phys.org / Why shame is an evolution-based defense mechanism
It is unpleasant, strange and often comes as a surprise: shame. But why do we feel it? An international study has shed new light on the emotion of shame, which has long been considered harmful. The conclusion: Shame is not ...
Phys.org / Chemists snap together complex 3D molecules from highly reactive 'radicals'—without losing their shape
Building the complex 3D molecules needed for new medicines has always been a bit like assembling a puzzle with pieces that keep trying to flip over. Now, chemists at Scripps Research have found a way to snap two such molecular ...
Phys.org / How bacteria use acetyl coenzyme as a building block in the formation of cells
Researchers at the University of Greifswald have discovered a new mechanism by which bacteria such as Bacillus subtilis can regulate the production of the central metabolic molecule acetyl coenzyme A (Acetyl-CoA). Acetyl-CoA, ...
Phys.org / Ocean glow meets 3D printing with living gels that sense mechanical force
The integration of biological organisms into synthetic structures offers a radical new pathway for developing intelligent, self-powered materials. Researchers have pioneered an innovative approach to biomanufacturing by using ...
Phys.org / Even weak ocean models can provide valuable information for environmental forecasts, study shows
Oxygen depletion in the western Baltic Sea is not uncommon. Oxygen-poor conditions regularly occur in deeper waters, placing stress on marine ecosystems and, in extreme cases, causing fish kills. As ocean temperatures continue ...
