Confirming the pedigree of uranium cubes from Nazi Germany’s failed nuclear program
During World War II, Nazi Germany and the U.S. were racing to develop nuclear technology. Before Germany could succeed, Allied forces disrupted the program and confiscated some of the cubes of uranium at the heart of it.
The ultimate fate of…

Magnetic Fields on the Moon are the Remnant of an Ancient Core Dynamo
Presently, the moon does not have an internal magnetic field as it can be observed on Earth. However, there are localized regions on its surface up to several hundred kilometers in size where a very strong magnetic field prevails.
This has been…

Greenland Could Lose Ice Faster Than Any Century Since The Last Ice Age Ended
A new estimate using sheet modeling finds that Greenland’s rate of ice loss this century could outpace that of any century over the past 12,000 years, when the last Ice Age ended.
Scientists used reconstructions of ancient climate to drive the…

The Magnetic History of Ice
The history of our planet has been written, among other things, in the periodic reversal of its magnetic poles. Scientists at the Weizmann Institute of Science propose a new means of reading this historic record: in ice.
Their findings, which were…
