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 ...

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 ...

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 ...

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 ...

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 ...

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.

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 ...

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). ...

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 ...

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.

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 ...

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 ...
