Behavior of ultra-cold atoms and polar molecules modeled

Theoretical physicist Ana Maria Rey uses the computer, as well as pencil and paper, to develop mathematical models that describe the behavior of ultra-cold atoms. The idea is to use these systems to learn more about condensed ...

Siberian hamsters show what helps make seasonal clocks tick

Many animals, including humans, have internal clocks and calendars to help them regulate behavior, physiological functions and biological processes. Although scientists have extensively studied the timekeeping mechanisms ...

At the heart of the circadian clock

(Phys.org) —Cellular processes in most organisms are regulated by an internal clock, and proteins called cryptochromes are at the core of its central oscillator. The three dimensional structures of cryptochromes from mouse ...

Watching the cogwheels of the biological clock in living cells

Our master circadian clock resides in a small group of about 10'000 neurons in the brain, called the suprachiasmatic nucleus. However, similar clocks are ticking in nearly all cells of the body, as demonstrated by the group ...

The Antikythera time machine

Leonardo da Vinci may have left behind sketches of helicopters, tanks and submarines but it is rare that we find actual artifacts that seem so way ahead of their time. Almost like a science fiction tale of archaeologists ...
