Phys.org / Physicists introduce phase contrast to electron microscopy, delivering sharper images of our body's tiniest proteins
Nearly 100 years ago, a seemingly simple discovery revolutionized the microscope. The introduction of phase contrast, which garnered a Nobel Prize in 1953, brought into clear view structures inside cells that had previously ...
Phys.org / Why cells started sticking together could help explain how animals first evolved
A recent study by Ruibao Li and Jennah Dharamshi published in Nature may help us understand the beginnings of animal evolution billions of years ago. These findings are the result of a collaboration among researchers at Indiana ...
Phys.org / Silent prions reveal new cross-species chronic wasting disease risk in lab tests
Chronic wasting disease (CWD) is generally associated with animals. But a new study by researchers from the University of Calgary and international collaborators explored the potential for CWD to spread from deer, elk and ...
Phys.org / Organic molecule with ultranarrow emission spectrum could lead to better LEDs
Over the past several decades, light sources have gradually transitioned to light-emitting diodes, or LEDs, and inorganic LEDs are now used across a wide range of applications. In parallel, organic LEDs, or OLEDs, have become ...
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 / 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 / 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 / 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 / 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.
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, ...
