(Phys.org)—Geologists Robin Wordsworth and Raymond Pierrehumbert of the University of Chicago, suggest in a paper published in the journal Science that early Earth was kept warm enough for life to develop by collisions ...
In 2011, CMS presented early evidence that Upsilon (Υ) particles produced in lead-lead collisions "melt" as a consequence of interacting with the hot nuclear matter created in these heavy-ion interactions. CMS has since ...

(Phys.org)—Researchers at Georgia Tech's Georgia Robots and InTelligent Systems (GRITS) Laboratory have succeeded in programming a swarm of very tiny robots to figure out for themselves how to go about playing a tune on ...
Heavy ion collisions at CERN should be able to produce the shortest light pulses ever created. This was demonstrated by computer simulations at the Vienna University of Technology. The pulses are so short that they cannot ...

In the event that a giant asteroid is headed toward Earth, you'd better hope that it's blindingly white. A pale asteroid would reflect sunlight—and over time, this bouncing of photons off its surface could create enough ...

The Moon is believed to have formed from a collision, 4.5 billion years ago, between Earth and an impactor the size of Mars, known as "Theia." Over the past decades scientists have simulated this process and reproduced many ...
