Do you know the real price of a piece of beef? Here is a nice, round number to chew on: The environmental cost of beef is ten times that of dairy, eggs or poultry. This means that if you chose to eat a steak over an omelet, (assuming they have equal amounts of protein) the…

Horse latitudes, doldrums, calms of Cancer and Capricorn: These are all synonymous names for the forsaken regions of the oceans that sailors of previous eras cursed because the winds that once pushed their sails die out there for weeks at a time. (One suggested explanation for the name “horse latitudes” is that some had to…

“Billions of dollars are being spent on weapons of mass destruction. A small fraction of that could go so far to engage more Israeli and Arab scientists in collaborative projects in order to create a critical mass that will bring about peace.” The speaker is Dr. Zafra Lerman, President of the Malta Conferences Foundation, which…

Last month we reported on the first people who, around twelve thousand years ago, were lining their loved ones’ graves with flowers. This month, we have a piece on the “extinct” frog that was “resurrected” and then discovered to be a living fossil. Both of these studies were led by Israeli researchers from other institutions.…

Right above the tree tops — where most people might think there is just air — Prof. Dan Yakir sees a distinctive atmospheric layer in which all sorts of complex exchanges are taking place. CO2, of course, is one of the important ones, and we still don’t understand all of the ins and outs of…

You’ve heard of the carbon cycle, maybe even the nitrogen cycle. But have you given much thought lately to the sulfur cycle? New research in last week’s Science suggests that we should be paying a bit more attention to the way this element moves through the atmosphere, biosphere, oceans and land. Over the last 500…

Today’s science news from the Weizmann Institute covers research in neurobiology, environmental science and cancer immunology. • In the first, scientists identified a likely biological marker for autism that shows up even in very young children. Diagnoses of autism are generally not possible so early, as the signs typically appear gradually throughout the first 3-4…

These guys are as adept with a lug wrench as they are with a mass spectrometer. Prof. Dan Yakir (second from right) and members of his group had to become licensed truck drivers to operate their newest equipment – which is all packed into a custom-built truck for hauling around the country. Until now, Yakir…

Some of the best moments in my job as a Weizmann science writer are the times when a scientist I’m interviewing slips in a finding that shifts my understanding of how the world works. Not long ago, for instance, I was speaking with a researcher about his work on phytoplankton. Now, the fact that phytoplankton…
