Uncovering the secrets of white cell power
White blood cells push their way through barriers to get to infection sites.
How to mix the perfect cocktail
Drug cocktails such as those for treating cancer, like the alcoholic versions offered at the local bar, are best when the proper ingredients are mixed in the right proportions.
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.
Keeping up the pressure
In addition to the classic stress response in our bodies -- an acute reaction that gradually abates when the threat passes -- our bodies appear to have a separate mechanism that deals only with chronic stress.

Now Playing: TED Radio Hour

Digital Manipulation
Technology has reshaped our lives in amazing ways. But at what cost? This hour, TED speakers reveal how what we see, read, believe — even how we vote — can be manipulated by the technology we use. Guests include journalist Carole Cadwalladr, consumer advocate Finn Myrstad, writer and marketing professor Scott Galloway, behavioral designer Nir Eyal, and computer graphics researcher Doug Roble.

#530 Why Aren't We Dead Yet?
We only notice our immune systems when they aren't working properly, or when they're under attack. How does our immune system understand what bits of us are us, and what bits are invading germs and viruses? How different are human immune systems from the immune systems of other creatures? And is the immune system so often the target of sketchy medical advice? Those questions and more, this week in our conversation with author Idan Ben-Barak about his book "Why Aren't We Dead Yet?: The Survivor’s Guide to the Immune System".
