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.
How did scientists develop an effective vaccine for Covid-19 in less than a year? In this webinar, the American Committee welcomed Dr. Mikael Dolsten, Chief Scientific Officer and President, Worldwide Research, Development, and Medical at Pfizer. In conversation with former American Committee President and renowned AIDS researcher Dr. Jay Levy, Dr. Dolsten shed light on the breakthroughs that enabled his team, in collaboration with researchers around the world, to produce a viable vaccine at such an extraordinary speed. He also shared his own scientific journey, including the transformative semester he spent at the Weizmann Institute as a PhD student. During a dynamic Q&A led by CEO Dave Doneson, Dr. Dolsten discussed the role of basic science in advancing lifesaving technologies and treatments.

REHOVOT, ISRAEL—March 18, 2021—It’s not just how hot the fires burn – it’s also where they burn that matters. During the recent extreme fire season in Australia, which began in 2019 and burned into 2020, millions of tons of smoke particles were released into the atmosphere. Most of those particles followed a typical pattern and settled to the ground after a day or week; however, the particles created in fires burning in one area of the country managed to blanket the entire Southern Hemisphere for months. When studying particle-laden haze, two researchers at the Weizmann Institute of Science noticed puzzling spikes in a certain measurement, and tracked the elevated levels to the fires in that area. Next, as reported in Science, the Israeli scientists uncovered the “perfect storm” of circumstances that swept the particles emitted from those fires into the upper atmosphere and spread them over the entire Southern Hemisphere.

New Scientist reports on research showing that the Australian fires “led to record aerosol levels over the southern hemisphere.” Prof. Ilan Koren and Dr. Eitan Hirsch (Israel Institute for Biological Research) conducted the study.

A year into Covid-related shutdowns, we are seeing a host of devastating impacts unrelated to the illness itself. One of these is hunger.
Food insecurity – lack of consistent access to sufficient, nutritious food – was a major public-health concern before the pandemic. Climate change’s extended droughts, destructive fires and storms, and rising waters are wiping out resources in many areas, notably India and Africa. Poverty is another contributing factor, particularly in cities with “food deserts” where it is hard to find fresh fruit and vegetables and other healthy options. (Interestingly, the World Bank reports that “children who are properly nourished during the first 1,000 days of their lives are 33% more likely to escape poverty as adults.”)
REHOVOT, ISRAEL—March 17, 2021—To observe how a tiny ball of identical cells on its way to becoming a mammalian embryo first attaches to an awaiting uterine wall and then develops into the nervous system, heart, stomach, and limbs: This has been a highly sought-after grail in the field of embryonic development for nearly 100 years. Now, Prof. Jacob Hanna of the Weizmann Institute of Science and his group have accomplished this feat. The method they created for growing mouse embryos outside the womb during the initial stages after embryo implantation will give researchers an unprecedented tool for understanding the development program encoded in the genes, and may provide detailed insights into birth and developmental defects as well as those involved in embryo implantation. The results were published in Nature.

REHOVOT, ISRAEL—March 17, 2021—Cancer immunotherapy may get a boost from an unexpected direction: bacteria residing within tumor cells. In a new study published in Nature, researchers at the Weizmann Institute of Science and their collaborators have discovered that the immune system “sees” these bacteria and shown that they can be harnessed to provoke an immune reaction against the tumor. The study may also help clarify the connection between immunotherapy and the gut microbiome, explaining the findings of previous research showing that the microbiome affects the success of immunotherapy.

The New York Times reports on Prof. Jacob Hanna’s recent breakthrough: growing embryonic mice outside a uterus. The work could shed light on birth defects, reduce need for animal research, and more.

The Jerusalem Post covers findings by a team under Prof. Yardena Samuels showing that certain peptides alert the immune system to cancer cells, an approach that could improve immunotherapy and help clinicians better target the cancer.

Prof. Ido Amit and team found “30 genes that seem to be responsible” for treatment resistance in multiple myeloma. This could “help lead to more informed, personalized treatment for patients,” says The Jerusalem Post.
