To attain knowledge, add things every day. To attain wisdom, remove things every day.
Lao Tsu
Apparently our nervous systems develop according to the Chinese philosopher’s principle of being and not being. As our nerve cells grow, they send out long extensions – axons – throughout the developing…
Have you complained about the weather recently? On the gas giants at the edges of our solar system, Uranus and Neptune, hurricane-like storm systems as big around as Earth blow 1000 km/h winds for years on end.

But wait…What…
Poetry is finding its way into our consciousness at the Weizmann Institute: At the recent, fourth annual Science on Tap evening, which the Institute hosts in Tel Aviv, several poets joined in the fun, reading from their work before and after the talks given by scientists in over 60 filled-to-…
When we navigate through our environment, do we track mostly in two dimensions or in three? Clearly, we can move in all three dimensions, but does our internal map relate to the vertical direction in the same way as it does to the horizontal axes on the ground?
That question has not yet been…
Prof. Shafi Goldwasser, who is at both the Weizmann Institute and MIT, will receive the 2012 A.M. Turing Award, together with Prof. Silvio Micali of MIT. Goldwasser is only the third woman to receive the Award since its inception in 1966, and she is the third faculty member of the Weizmann…
Happy International Women's Day. In the midst of today's hand wringing about women in science, here's some good news: The Weizmann Institute has just been awarded a prize by the City of Barcelona for its efforts to promote women in science. Above: Barcelona Civil Rights councilor Francina Vila i…
Another advance in cancer research is featured on our website this week. Among other things, this one highlights the dangers of assuming causation from correlation. Prof. Dov Zipori and his team were looking at adult stem cells in the bone marrow. These hold a lot of potential for treating many…
New research at the Institute may offer a sliver of hope for treating “triple-negative” breast cancer. “Triple-negative” refers to the fact that the breast cancer cells are missing the three different receptors targeted by the currently available drugs, for instance Herceptin and steroid hormone…
What happens when a former physics-student-turned-documentary-director is invited to create a video clip for the first ever physics reunion? The answer is below.
You may not learn anything new about physics by watching it, but you will note that Weizmann President Prof. Daniel Zajfman and VP…
Does your face reveal what’s in your heart? It might – even more than you know. Take, for instance, a common group of birth defects – forms of a disorder called DiGeorge syndrome. Around one in 4000 is born with this syndrome, which arises from a deletion of a short segment of chromosome 22. …
At the beginning of the year, we published an interview with Dr. Zohar Komargodski on this blog. Apparently we were not the only ones impressed by Komargodski’s accomplishments: The Fundamental Physics Prize Foundation has announced that he will be one of three recipients of a New Horizons in…
Is anyone old enough to remember the ad in which two people walking down the street while snacking accidently bump into each other and discover peanut butter on a chocolate bar? Well, it turns out that when physics students run into each other on the street, the result is a quasicrystal with…
Weizmann Institute scientists have created a “white smell.” Think about white light or white noise: Each mixes a bunch of different waves together from various parts of the visual or audible spectrum. Those wavelengths combine such that we perceive that unobtrusive light or sound we call “white.”…
The idea of “seeing the world through the eyes of a child” takes on new meaning when the observer is a computer. Institute scientists in the Lab for Vision and Robotics Research took their computer right back to babyhood and used it to ask how infants first learn to identify objects in their visual…
We have been told what it’s like to be a bat or a bird; now Prof. Ehud Ahissar and Dr. Avi Saig are getting people to experience what it’s like to be a rat. Specifically, they want the participants in their studies to learn what it’s like to locate things in the dark by twitching their whiskers.…
“The public, blog-fueled controversy over the utilization of arsenate instead of phosphate in bacteria was, in the end, a demonstration of what is truly right with scientific quests,” says Prof. Dan Tawfik. “The original findings (that certain bacteria can use arsenate instead of phosphate) may…
Today’s post is about some cool chemistry – very cool. About 0.01°Kelvin, as a matter of fact (that is, one hundredth of a degree above absolute zero). Physics experiments conducted at such temperatures are already old hat, but chemistry is another story, altogether. Scientists have been attempting…
One of our constant themes is the innovative ways that tools and ideas from math and physics can lead to new insights in the life sciences. Take, for example, a recent study produced by a group that included a professor of mathematics, an oncologist who works in pharmaceutical research and has a Ph…
“Imagine that you wake up in the morning feeling nothing special, yet you find yourself inexplicably behaving just a bit differently during the day. For example, you take a sniff every time you hear a tone,” says Prof. Noam Sobel. Of course, the people this actually happened to knew they had…
We recently witnessed the disagreement over the official memorial for the 11 Israeli athletes killed at the Munich Olympics 40 years ago. Fewer remember the terrorist attack in the Lod airport a few months earlier – in May – in which 24 people lost their lives. One of those was the head of the…
Science magazine seemed to imply there was some grousing about the new Fundamental Physics Prizes awarded by billionaire Yuri Milner, but we in Rehovot think it’s a good thing. While one can quibble about which fields are still underfunded, we believe that any support for truly basic research --…
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.…
We were just getting used to the idea of our digestive tract as an ecosystem. There are 10 times as many bacteria in our gut as there are cells in our bodies, and the ecological balance between the different types might affect everything from our tendency to gain weight to our general health and…
Rose Eveleth talks to Assaf Vardi today on the Scientific American Expeditions blog:
http://blogs.scientificamerican.com/expeditions/2012/07/11/you-wanted-to-know-who-are-these-scientists-introducing-assaf-vard
One of our scientists, Dr. Assaf Vardi, is off on a month-long cruise. He is on the Knorr, a research vessel operated by the Woods Hole Oceanographic Institute, with a team from the Weizmann Institute and another four research teams on a route that will take them from the Azores to Iceland. On the…
Blurring, chopping and blocking. Three online items this week all deal with some pretty dynamic phenomena.
The blurring is in our perceptions. It turns out that if you even think you have lost money in an experiment, your ability to distinguish between musical notes will be hampered. What’s the…
Geneticist Dr. Maya Schuldiner has a lab full of the latest, shiniest robotic equipment. So why is she showing us pictures of socks? What she and her lab group mean to illustrate is that they have trained their research robots to find pairs – not of socks, alas, but of proteins.
The team and their…
Would you learn a language by taking a written text and changing letters here and there, or moving a few words around, and asking whether the meaning has changed? That may not be the most efficient way to learn French, but a Weizmann Institute scientist is betting that it will be a very useful way…
Not many Israelis make it all the way to the South Pole. (In fact, very few people go there, at all. Not only is it really, really cold, it is extremely difficult and expensive to transport people, gear and necessities to this remote and inhospitable corner of the earth.) So when we learned that Dr…
New online articles this week highlight two forays into the world of synthetic biology. Each, in its own way, gives a different perspective on how sophisticated the field has become in the past few years, since smiley-face DNA was first introduced.
Prof. Benjamin Geiger of the Weizmann Institute…
