Gene analysis adds layers to understanding how our livers function
In a study reported recently in Nature, Weizmann Institute of Science researchers showed that the liver's amazing multitasking capacity is due at least in part to a clever division of labor among its cells.
Crystallization made crystal clear
Researchers at the Weizmann Institute of Science have, for the first time, directly observed the process of crystallization on the molecular level, validating some recent theories about crystallization, as well as showing that if one knows how the crystal starts growing, one can predict the end structure.
Explosive material: The making of a supernova
Pre-supernova stars may show signs of instability for months before the big explosion
A rusty green early ocean?
Dr. Itay Halevy and his group in the Weizmann Institute of Science's Earth and Planetary Sciences Department suggest that billions of years ago, the 'rust' that formed in the seawater and sank to the ocean bed was green -- an iron-based mineral that is rare on Earth today but might once have been relatively common.
First oceans may have been acidic
Dr. Itay Halevy of the Weizmann Institute of Science has looked to the distant past -- all the way back to Earth's earliest oceans.
Controlling electron spin for efficient water splitting
The method could lead to solar-based production of hydrogen for fuel.
Programmed proteins might help prevent malaria
A new approach to stabilizing protein structures could be key to an efficient vaccine.

Imaging CoE scientists have solved a 40-year old mystery and shed light on an evolutionary arms race played out between cytomegalovirus (CMV) and the immune system.
In search of the wild fava bean
Seeds from a site in Northern Israel are the ancestors of today's fava beans.

Dispatch 6: Strange Times
Covid has disrupted the most basic routines of our days and nights. But in the middle of a conversation about how to fight the virus, we find a place impervious to the stalled plans and frenetic demands of the outside world. It's a very different kind of front line, where urgent work means moving slow, and time is marked out in tiny pre-planned steps. Then, on a walk through the woods, we consider how the tempo of our lives affects our minds and discover how the beats of biology shape our bodies. This episode was produced with help from Molly Webster and Tracie Hunte. Support Radiolab today at Radiolab.org/donate.
