A “walk” in composition space for a “Lipid World” molecular assembly, shown in simplified 3D. A point on the line signifies a specific composition along the time axis, whereby the three coordinates are amounts of the three different molecule types. A “composome” (pink background) is a time interval when the composition stays almost unchanged, signifying compositional replication.
In 1924, Russian biochemist Alexander Oparin claimed that life on Earth developed through gradual chemical changes of organic molecules in the “primordial soup” that likely existed here four billion years ago. In his view, the complex combination of lifeless molecules, joining forces within small oily droplets, could assume life faculties – self-replication, selection, and evolution. These ideas were received with considerable doubt, which remains today.
Feb 13, 2017... Water is made of oxygen and hydrogen, and splitting water molecules to produce hydrogen for fuel is a promising path for alternative energy. One of the main obstacles to making hydrogen production a reality is that current methods of water splitting result in hydrogen peroxide also being formed, which affects both the efficiency of the reaction and the stability of the production process. Israeli and Dutch researchers from the Weizmann Institute of Science and Eindhoven University of Technology, respectively, have succeeded in almost fully suppressing the production of hydrogen peroxide by controlling the spin of electrons in the reaction. The group recently published their findings in the Journal of the American Chemical Society. The efficient production of hydrogen paves the way toward the use of solar energy to split water.

Talking to: Prof. Noam Sobel of the neurobiology department and the Azrieli Center for Human Brain Imaging, Weizmann Institute of Science, in Rehovot, who studies brain mechanisms related to the sense of smell. Where: His laboratory. When: Sunday, 10 A.M.
How does the sense of smell affect human behavior?
Our primary field of research dealing with that question concerns chemical communication between animals, and in our case, human beings. All animals communicate by means of chemical signals, and we, too, land mammals with an amazing nose, are no different.

Following a 5,000 km long ocean survey, research published in the Proceedings of the National Academy of Sciences presents a new way to measure how the acidification of water is affecting marine ecosystems over an entire oceanic basin.

Anchored by a Congressional health education program, Men’s Health Month aims to heighten awareness of preventable health problems and encourage early detection and treatment of disease.
The broad-ranging research of Weizmann Institute scientists addresses multiple areas of men’s health, including fighting cancers that are common to men. According to the Centers for Disease Control (CDC), “Every year, cancer claims the lives of nearly 300,000 men in America.” Weizmann research, such as a method for timely detection of prostate cancer, can help protect our fathers, brothers, husbands, friends. Read on for just a few examples of how Institute science is benefitting men’s health.

REHOVOT, ISRAEL—May 29, 2008—A Weizmann Institute study provides important new insights into the process of viral infection. The study, reported in the online journal PLoS Biology, reveals certain mechanisms by which mimivirus—a virus so called because it was originally thought to mimic bacteria in various aspects of their behavior—invades amoeba cells.
Living cells become infected by viruses in two steps. First, the virus penetrates the cell. Next, in the second and crucial step, the cell starts producing new viruses, which spread and infect additional cells. At the beginning of this production process, the cell makes the outer wall of the virus, which is a container of sorts composed of proteins and known as the capsid. The cell then makes copies of viral DNA and inserts it into the capsid. The result is a new, functioning virus that is ready to leave the host cell and infect more cells.

October 7, 2009—The American Committee for the Weizmann Institute of Science congratulates Prof. Ada Yonath on receiving the 2009 Nobel Prize in Chemistry and is proud of her scientific achievements. We are delighted that the Nobel Committee for Chemistry has recognized the significance of Prof. Yonath's scientific research and awarded her this important prize.
Prof. Yonath's research is driven by curiosity and ambition to better understand the world and our place within it. This research aims high: to understand one of the most complicated "machines" of the biological system.

A report on a fundamentally new and unprecedented molecular closed-cage nanostructure, produced by immensely concentrated sunlight was published recently by a team combining researchers in Beersheba, Rehovot and Russia. Ben-Gurion University of the Negev Profs. Jeffrey Gordon and Daniel Feuermann, Prof. Reshef Tenne’s group at the Weizmann Institute of Science, and Dr. Andrey Enyashin at the Ural Federal University explained their work in a recent issue of one of the foremost journals in nanotechnology, ACS Nano.

Two new studies support a novel approach based on Weizmann Institute scientists’ research
Much of the devastation of stroke and head trauma is due to damage caused by the overproduction of a substance in the brain called glutamate. Preventing this damage has been impossible, until now, as many drugs don’t cross the blood-brain barrier, and those that do often don’t work as intended. But a method originally devised at the Weizmann Institute of Science may, in the future, offer a way to avert such glutamate-induced harm.
