The Weizmann Institute's Prof. Nava Dekel discovered that performing a uterine biopsy just before a woman undergoes in vitro fertilization (IVF) doubles the chances of a successful pregnancy. Her method is now being used by women all over the world.
Prof. Yadin Dudai's groundbreaking neuroscience research includes identifying a way to erase memories; the discovery that a brain enzyme can improve memories, even older ones; and the finding that social pressure can lead to falsified memories.
Prof. Noam Sobel and his team of neurobiologists at the Weizmann Institute invented a device that enables quadriplegic persons to drive a wheelchair and locked-in patients to write using a computer–all by sniffing. The revolutionary, easy-to-use device is being studied for other uses as well.
Weizmann scientists have identified a single gene linking stress to obesity and diabetes, and have shown that the gene's action in the brain has profound effects on the metabolism of the whole body.
Prof. Michal Schwartz and her team at the Weizmann Institute developed a treatment to regenerate damaged nerves in the spinal cord. This innovative approach involves boosting the body's natural immune mechanisms to improve the outcome of trauma.
Weizmann immunologist Prof. Irun Cohen has developed a vaccine that stops the progression of type 1,
or juvenile, diabetes by blocking the destruction of insulin-secreting pancreatic cells. The vaccine
is in clinical trials.
Stem cell research by Weizmann’s Prof. Yair Reisner yielded the creation of functioning human kidneys
in mice, offering hope for patients suffering from organ failure. The ability to “grow” new organs would
save untold numbers of lives.
Weizmann scientists discovered that stem cells in bone marrow can transform into liver cells and help repair a damaged liver–the second most-sought organ for transplantation in the U.S.
Weizmann’s Profs. Joel Sussman and Israel Silman discovered the molecular spatial structure of
acetylcholinesterase (AChE), a brain enzyme thought to play a crucial role in Alzheimer’s disease.
Their research is helping pave the way for the design of novel drugs for this devastating condition.
In 1956, Weizmann Institute Prof. Leo Sachs and his colleagues published a scientific paper that
led to the clinical application of amniocentesis, now routinely used all over the world.
Weizmann scientists have found that a membrane in the inner ear is rigid at one end and flexible at the
other—a gradation that may allow the ear to distinguish between frequencies. This could provide
insight into correcting some forms of hearing impairment and may enable the design of better hearing aids.
In the 1950's, Weizmann Institute laboratories yielded heavy-oxygen water for the study of basic processes
such as respiration, brain chemistry, and photosynthesis. Today, this technology is used in advanced medical
imaging scans such as positron emission tomography (PET).
A Weizmann scientist developed a blood test that may be used to screen for schizophrenia.
The mental disorder, which affects more than two million Americans, is currently diagnosed
only through behavioral methods.
A beta-carotene-based health food product with possible anti-cancer properties is derived from Dunaliella
algae through a process developed at the Weizmann Institute.
The Weizmann Institute’s Prof. Ada Yonath won the 2009 Nobel Prize in Chemistry for crystallizing and
deciphering the structure of the ribosome, the cell’s protein factory. Her achievement helps clarify the
exact mode of action of antibiotic drugs and is aiding in the fight against antibiotic-resistant bacteria.
A Weizmann scientist revealed that the positioning of nucleosomes–spheres of DNA compressed around proteins and strung like beads along the chromosomes–is encoded in the genes themselves. This discovery, which received global attention, may help in designing gene therapies.
Multiple sclerosis (MS) affects 2.5 million people worldwide. Copaxone® and Rebif®, two FDA-approved
drugs that are now frontline treatments for MS, were developed based on Weizmann research.
Prof. Dan Tawfik and his team of Weizmann scientists successfully designed artificial enzymes that
undergo “evolution” in a test tube, with exponentially faster reaction rates. This achievement opens
the door to the development of numerous potential applications in medicine and industry.
When the brain is injured, a neurotransmitter called glutamate floods the brain, damaging it.
Weizmann’s Prof. Vivian Teichberg has developed a method that causes the excess glutamate
to exit the brain quickly and pass harmlessly into the blood.

Years ago, a little girl told Rita J. King that she was the only grown-up who gave her hope that her imagination didn’t have to die when she became an adult. In the time since, Rita has devoted herself to the development of the Imagination Age, a period of collaboratively imagining and inhabiting a future built on science, math, engineering and most of all—creativity. She directs Science House Creative.
Tomorrow Lab for Humanity was created as a place to explore the state of science today and its impact on you. We've loaded this section with the latest data, news and information about our Health & Medicine and the ways in which we are working to improve it every day.
