Founded in 1944, the American Committee for the Weizmann Institute of Science develops philanthropic support for the Weizmann Institute in Israel, and advances its mission of science for the benefit of humanity.
Nov 27, 2019... REHOVOT, ISRAEL—November 27, 2019—Bacteria in the lab of Prof. Ron Milo of the Weizmann Institute of Science have not just sworn off sugar – they have stopped eating all of their normal solid food, existing instead on carbon dioxide (CO2) from their environment. That is, they were able to build all of their biomass from air. This feat, which involved nearly a decade of rational design, genetic engineering, and a sped-up version of evolution in the lab, was reported in Cell. The findings point to means of developing, in the future, carbon-neutral fuels.
Jun 02, 2007... Prof. Doron Lancet of the Department of Molecular Genetics at the Weizmann Institute of Science is one of Israel's most prominent genome researchers. The head of the Crown Human Genome Center, Prof. Lancet has directed research on DNA chips, disease genes, and genes responsible for smell and taste, and is currently working to develop a computational model for the origin of life on earth. Because the Weizmann Institute was Israel's liaison to the international Human Genome Project, Prof. Lancet and his colleagues have unusually intimate knowledge of the field of genomics and its implications.
Dec 19, 2017... The Weizmann Institute of Science in Rehovot, Israel, today announced the installation of the Biospec® 15.2 Tesla USR™ preclinical ultra-high field magnetic resonance imaging (MRI) instrument from Bruker. The new instrument is installed in the Daniel Wolf building of the Department of Chemical Research, and is used by the MRI Biosensors laboratory, led by Dr. Bar-Shir, and the laboratory of Professor Neeman, to open new frontiers in molecular and microscopic imaging, adding to the team’s existing world-class MRI instruments.
Oct 31, 2019... The ocean is one of the largest and most mysterious ecosystems on Earth. In the tenth episode of Weizmann in Focus, Dave Doneson describes the fascinating research of Weizmann Profs. Ilan Koren and Assaf Vardi who set sail aboard the Tara schooner to unlock some of these mysteries. They were among a select group of scientists who traveled thousands of kilometers across all the world’s oceans to advance research and increase environmental awareness. The research conducted on board the schooner yielded hundreds of scientific papers as well as a better understanding of the ocean ecosystem and how it impacts the entire planet.

Israeli scientists from the Technion-Israel Institute of Technology and the Weizmann Institute of Science recently combined one group’s expertise in tissue engineering with the other’s expertise in the physics of complex systems to understand in detail how mechanical forces can direct the orientation of developing blood vessels.

Jul 28, 2014... Using the body’s natural virus killers to prevent and treat HIV infection has been problematic until now because of the strong inflammatory response these molecules can stimulate as they get rid of the invaders. Now, collaborative research conducted by scientists at the Weizmann Institute and the National Institutes of Health (NIH) have demonstrated how suppressing the activity of these molecules – interferons – around the time of infection could have long-term implications for the course of the disease. Their research appeared in Nature.

“The composition of intestinal bacteria affects the decisions made by our brain. The more I learned about intestinal bacteria, the more it kept me awake at night,” says DayTwo founder and CEO Lihi Segal. Her company is using the breakthrough science of intestinal bacteria for commercial purposes.
The composition of intestinal bacteria is set in most people by age 2, and thereafter changes only slightly. DayTwo’s technology is based on research at the Weizmann Institute led by Prof. Eran Segal and Dr. Eran Elinav, which was first reported in “Globes” in 2013. This research showed that the composition of intestinal bacteria, which is unique for each person, has a differential impact on how that person responds to certain food, and specifically on his blood sugar levels. Eating a banana might greatly increase the blood sugar level for one person with a certain intestinal bacteria composition and eating an apple would not, while another person might have opposite responses to the two fruits.

Mar 15, 2011... More than 220 million people around the world suffer from diabetes, a chronic condition in which abnormally high levels of glucose (sugar) circulate in the blood. Type 2 diabetes, the most common form of the disease, develops when the body cannot adequately produce, or improperly uses, insulin, a hormone that regulates blood sugar levels. People with type 2 diabetes are at an increased risk for many serious health problems, including heart disease, blindness, and kidney damage. Notably, according to the National Institutes of Health, more than 85 percent of those with type 2 diabetes are overweight.

Cotton fibers modified to glow under ultraviolet light. (Filipe Natalio)
Seven or eight thousand years ago, humans figured out that the natural fibers cotton plants produce could be spun into strands and woven into fabric. During the Industrial Revolution and after, it became one of the world’s most valuable commodities—and helped drive the slave trade in the Americas and Europe.
Cotton is great. It's soft and light and durable enough. It’s pretty warm and dries pretty fast. But is that really all it can do for us? Filipe Natalio, a chemist at the Weizmann Institute of Science in Israel, thinks cotton can do better.

A bacterium that some scientists thought could use arsenic in place of phosphorus in its DNA actually goes to extreme lengths to grab any traces of phosphorus it can find.
The finding clears up a lingering question sparked by a controversial study, published in Science in 2010, which claimed that the GFAJ-1 microbe could thrive in the high-arsenic conditions of Mono Lake in California without metabolizing phosphorus — an element that is essential for all forms of life.
