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.
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 / CO₂ injection reveals hidden cement chemistry behind 13% stronger early strength
One September day, it started to snow inside MIT's Pierce Laboratory. Researchers depressurized a tank of liquid carbon dioxide (CO2), instantly freezing it and releasing solid flakes. These were blended into cement paste ...
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 / 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 / Would you return a favor? Scientists say it depends on the relationship
When a friend buys you a cup of coffee, it's likely that next time, you'll return the gesture. This type of reciprocal generosity has been well-documented in behavioral economics studies. However, anthropologists and other ...
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 / 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 / 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 / Why animal calls sound alike in time: Most species share a common communication tempo
From insects to great apes, by way of birds and fish, animals communicate through an extraordinary variety of sounds. While the pitch or timbre of their vocalizations matters, rhythm may play a more fundamental role. Scientists ...
Phys.org / Salmonella genomes reveal 45 previously unknown toxins in foodborne bacteria
Researchers at the University of São Paulo (USP) in Brazil have discovered 45 new toxins produced by Salmonella bacteria, some of which are associated with foodborne infections. The study was conducted at the Center for Research ...
