The mass of mammals in the world. Only 6% are animals in Remy weighs more? The biomass of humans, of farm and pet animals, and of wild mammals (Illustration: Itay Reva)

Life at stake: the weight of wild mammals dwarfs that of farm animals

The biomass of cows, pigs, sheep and other farm animals is currently 30 times greater than that of all elephants, elk and other wild land mammals combined

NASA will launch the first Israeli space telescope ULTRASAT

The space telescope, a flagship project of the Weizmann Institute of Science and the Israel Space Agency, will be launched in 2026 and is expected to revolutionize space exploration
The setup the researchers use: a thin membrane made of diamond 30 microns thick with an average of one sensor at the top end of each column. The top image - magnification 2,640 times, the bottom - 32,650 times

Like Lego figures, proteins can don a variety of costumes - chemical tags that change them beyond recognition. The new method makes it possible to identify about 30 tags within six hours, compared to only three tags within two weeks with the existing methods

The protein wears Prada

In response to environmental and intracellular changes, the proteins in our body don a variety of costumes that change their properties and make their identification difficult. The institute's scientists have developed a ground-breaking search engine capable of efficiently identifying these proteins

Relaxed from birth

Weizmann Institute scientists have discovered that certain fish are born with immunity to stressful situations, which accompanies them throughout their lives and is even inherited. The findings may pave new directions for the treatment of post-trauma
Diagram showing the neural circuit for sensing danger in the female worms (above), the male worms (center), and the transgenic male worms (below) which adopted female behavior following the creation of a connection between two nerve cells in the circuit

Scientists added only one connection between two nerve cells in worms. This was enough to turn male behavior into female

The research findings illustrate how changing the synapse map may lead to a change in behavior

An innovative therapeutic approach mobilizes viruses to intercept disease-causing gut bacteria

In a study published today in the scientific journal Cell, Weizmann Institute of Science scientists demonstrated an innovative therapeutic approach that performs "targeted defeat" of unwanted intestinal bacteria using a creative and precise weapon - viruses that attack

Prof. Jacob Segiv from the Weizmann Institute - the first Israeli to win the Kovli Prize for Nanotechnology on behalf of the King of Norway

  • No comments
Segiv and three of his colleagues from the USA won the prize for their contribution to the development of self-assembling materials * The research opens the foundations for building much smaller chips and developing a completely new type of medical diagnostic products
The electronic nose used by the researchers. Smells potential for brave friendships

Humans tend to make friends with those who have a similar body odor to their own

This is according to a new study by Weizmann Institute scientists. Moreover, the scientists were able to predict in the study what the degree of connection between complete strangers would be just on the basis of their smell as picked up by an "electronic nose"

Rare evidence of the use of fire more than 800 years ago was uncovered at an archaeological site in the Galilee

The findings obtained through an innovative method based on artificial intelligence are some of the earliest evidence of the use of fire in Israel and in the world
Schematic diagram of the pyruvate dehydrogenase (PDC) protein complex. Responsible for the transition between the metabolic pathways for the breakdown of sucralose and the production of energy in the mitochondrion ("Krebs cycle"). On the left: the classic move as it was known until now with the addition of the research hypothesis (marked with a question mark), on the right: the move as observed in transgenic mice without enzymes from the PDK family. The backup plan revealed in the study is highlighted with an exclamation mark

Opening a circle

Institute scientists are updating a version of one of the most classic diagrams in biochemistry books - the Krebs circle
Schematic diagram of the bacterial operon (top) versus the eukaryotic transferron (bottom). According to the researchers, instead of "beads on a string" a kind of genetic "stroke-na" game developed during evolution that allows using the same "letters" - that is, messenger RNA molecules originating from genes located on different chromosomes - to create different "words", i.e. different transferrons

How did evolution overcome the lack of order in the storage of genetic information in the transition from bacteria to more developed creatures?

A body odor molecule common in babies reduces aggression in men and increases it in women

These findings are among the first to directly link human behavior, brain mechanism and smell molecule
Simulating the collision as it could have been if the detector was more accurate (in the top image), allows the computer to be taught to analyze the collision more accurately and efficiently (in the bottom image). The red lines indicate the trajectory of the particles after the collision

Contrary to the image they got, the DNA molecules in the cell nucleus do not float in the center and do not fill most of its volume
