How do microbes survive in freezing conditions?

Most microbial researchers grow their cells in petri-dishes to study how they respond to stress and damaging conditions. But, with the support of funding from NASA, researchers in LSU’s Department of Biological Sciences tried something almost unheard of: studying microbial survival in ice to understand how microorganisms could survive in ancient permafrost, or perhaps even buried in ice on Mars.

Freezing antimatter could pin it down for study

Antimatter's not the easiest stuff to work with - the minute it encounters ordinary matter it self-destructs. Now, though, scientists believe they've found a way to keep it in one place for long enough to study, by cooling it right down.

Sunspots linked to weather

German scientists say they've confirmed something long suspected: that the weather in some regions of Earth is influenced by the sun's 11-year cycle of activity.

Earth's core is melting - and freezing

The inner core of the Earth appears to be simultaneously melting and freezing, because of heat circulation in the rocky mantle that covers it.
