Phys.org / Scientists find the climate and health impacts of natural gas stoves are greater than previously thought

Humans have cooked with fire for millennia, but it may be time for a change. Natural gas appliances warm the planet in two ways: generating carbon dioxide by burning natural gas as a fuel and leaking unburned methane into ...

Phys.org / When fossils come to life: SARS-CoV-2 spike, syncytin-1, and other curious fusion proteins

The homotrimeric spike glycoprotein (S) from SARS-CoV-2, particularly its S2 subunit, is a fusion protein extraordinaire. It can fuse viral particles to cells and also fuse cells to cells to create multifarious syncytia among ...

Phys.org / What wintering squirrels can teach astronauts

When bears and ground squirrels hibernate in winter, they stop eating, lasting until spring simply on the fat reserves they've stored up in their bodies. Usually, this sort of prolonged fasting and inactivity would significantly ...

Phys.org / Decreasing development on forest and agricultural land partly driven by gas prices, study finds

A new study found a steep decline in the development of forest and agricultural land from 2000 to 2015 compared to the previous two decades, which resulted in a broad shift towards denser development patterns throughout the ...

Phys.org / Morphological fingerprinting could help identify side effects and new bioactive compounds in drug discovery

Pharmaceutical researchers speak of a hit when they come across a promising substance with a desired effect in early drug discovery. Unfortunately, hits are rarely bull's-eyes, often showing undesirable side effects that ...
