Phys.org / Dry seeds preserve fully formed mitochondria, unlocking rapid energy at germination

The majority of plant seeds have the special ability to almost completely dry out and yet remain viable. While most living cells die with a 90% loss of water, cells in seeds enter a biological state of dormancy. With a moisture ...

Phys.org / Fossil-fuel carbon fingerprint reaches the deep North Atlantic

The use of fossil fuels alters both the concentration and the carbon isotope composition of carbon dioxide in the atmosphere. Since surface water exchanges carbon dioxide with the atmosphere, this also alters the isotopic ...

Phys.org / Liquid gallium experiment confirms key flow regime inside rapidly rotating stars and planets

Since we cannot look into the interiors of stars and planets, we rely on lab experiments to replicate the physical processes that occur there. Led by the University of California, Los Angeles (UCLA), an international research ...
