Phys.org / Data reveal a significant acceleration of global warming since 2015

Global warming has accelerated since 2015, according to a new study by the Potsdam Institute for Climate Impact Research (PIK). After accounting for known natural influences on global temperature, the research team detected ...

Phys.org / A new 'molecular switch' for inborn immunity identified

Innate immune sensors—known as pattern recognition receptors (PRRs)—detect specific molecular components of bacterial or viral intruders. The PRRs forward the signals which results in the production of interferons, which ...

Phys.org / Meet 'Tous'—an entirely new genus of mammal

Mammals are not especially diverse. Roughly 6,800 mammal species are known to exist, compared with about 8,800 species of amphibian, 11,000 species of bird and 12,500 of reptile. Yet when most people picture biodiversity, ...

Phys.org / Missing technosignatures? Turbulent plasma may blur ultra-narrow signals before they leave their home star systems

A new study by researchers at the SETI Institute suggests that stellar "space weather" could make radio signals from extraterrestrial intelligence harder to detect. Stellar activity and plasma turbulence near a transmitting ...
