A new study from Caltech suggests the early Earth formed from hot, dry materials, implying water arrived late in Earth's formation. The research, offering clues from different mantle layers, posits major additions of volatiles only happened during Earth's final formation stages, impacting theories o

Experiments performed by ETH scientists have shown that it is remarkably easy for protein-like, two-dimensional structures—amyloids—to form from basic building blocks. This discovery supports the researchers' hypothesis that primal life could have evolved from amyloids such as these.

Twenty of the warmest years on record have been in the past 22 years, say the World Meteorological Organization.
