There are gambles, and there are gambles. In a lottery, a modest investment buys a tiny chance of winning a fortune, while in Russian roulette, you run a fairly high risk of losing big-time. Evolution is a high-stakes game that combines features of both. Its instrument, mutation,...

May 1, 2000
"Shoot the messenger" is apparently the name of the game in the body's protein regulation system. Researchers at the Weizmann Institute of Science have discovered that the synthesis and regulation of actin, the most abundant protein in human cells, is based on destroying its...

May 1, 2005
Your average billiards player down at the local hall might not be aware that the table he’s playing on represents a complex mathematical problem. Imagine a frictionless (and pocketless) billiard table on which a ball bounces endlessly from wall to wall. Though a seasoned billiard...

May 1, 2000
It is generally assumed that human beings invented the wheel, but as Prof. Irith Ginzburg shows in an article published in the Journal of Neuroscience, wheel-borne carriages fitted on tracks and led by coachmen have always existed within us - in our ner...

May 1, 2000
Acetylcholine plays a double role in learning and memory, says a team of scientists from the Weizmann Institute and France's Centre National de la Recherche Scientifique (CNRS). Prior studies had demonstrated that adding this neurotransmitter to neuro...

May 1, 2000
Weizmann Institute researchers recently got more than they'd bargained for. While studying an enzyme pivotal to brain function and memory, they changed an experimental focus and ended up capturing the first-ever time-resolved "movie" demonstrating how molecules break...

They volunteer in the largest army in the world. They don't get uniforms, or boots, or a paycheck, but they're heavily armed. They patrol, check identification, isolate and render harmless all suspicious objects, and fight every battle to the death. Their mission: to guard a...

May 1, 2005
Genes may contain the blueprint for life, but they’re written more like coded messages in a spy thriller: Short segments of DNA carrying instructions for protein formation are imbedded in a longer text, and interspersed with “filler” DNA that has no known function. The pictu...

May 1, 2005
Hundreds of potential drugs never make it to the clinic because they don’t stay in the body long enough to do their job. Small proteins shown to be effective against disease are often cleared by the kidneys within minutes and therefore cannot serve as drugs. Now Weizmann Institut...
