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.
One of the first organ systems to form and function in the embryo is the cardiovascular system: in fact, this developmental process starts so early that scientists still have many unresolved questions on the origin of the primitive heart and blood vessels. How do the first cells – the progenitors – that are destined to become part of this system participate in shaping the developed cardiovascular system? Dr. Lyad Zamir, a former PhD student in the lab of Prof. Eldad Tzahor in the Weizmann Institute of Science’s Department of Molecular Cell Biology, developed a method to image the earliest cardiovascular progenitors and track them and their descendants through the developing embryo in real time. His movies took place in fertilized chicken eggs, in which a complex network of blood vessels forms within the yolk sac to nourish the embryo. The findings of this research were recently published in eLife.

Every time we swallow food, cells that line the intestines must step up their activity in a sudden and dramatic manner. According to a new study by Weizmann Institute of Science researchers, reported in Science, they rise to the challenge in the most economic fashion. In business or engineering, when one has to get production underway quickly, instant decisions are made. These might involve instantly throwing all one’s resources into boosting production with existing equipment, or else first spending all those resources to equip the plant with proper machinery. The latter might seem to be a less efficient production method but it can actually, in some cases, speed things up considerably. Dr. Shalev Itzkovitz and his team in the Department of Molecular Cell Biology discovered that this is just the method adopted in the lining of the intestinal wall.

The Nature Index of Innovation, published August 9, 2017, places the Weizmann Institute of Science in sixth place in an international ranking of the world’s top 200 research institutions. To determine placements, the Nature Index – affiliated with renowned scientific journal Nature – examined how research articles are cited in third-party patents, then ranked the institutions according to the impact produced by their academic research.The rationale for this process is that by looking at patents owned by third parties – informed by and citing academic work – rather than those held by institutions themselves, the influence of research on the development of products and services is exposed. According to Nature, the academic players featured in the index are those “whose ideas may shape tomorrow’s inventions. The top of these tables are occupied by both institutions with global reputations for high-quality research and others whose published work is having a disproportionately high impact relative to their size.”

Scientists have managed to design microscopic silk capsules that mimic, on a very small scale, the structure of silkworm cocoons. The capsules can serve as a protective environment for the transport of sensitive “cargo” such as natural silk proteins, antibodies, or other delicate molecules. The collaborative research – which was performed by an international team of academics from the Weizmann Institute of Science in Israel; the Universities of Cambridge, Oxford, and Sheffield in the UK; and the ETH in Switzerland – may lead to a host of applications in the cosmetics, food, and pharmaceutical industries, particularly in the delivery of drugs within the body. The findings were reported in Nature Communications.

A water tank concealed below the eastern patio, cork insulation inside the walls, and a drainage system hidden in the columns of the pool – these are just a few of unique features uncovered as Weizmann House underwent an extensive restoration and conservation process over the past year. The house has now reopened to the public. More than 80 years after it was built, the house of the first president of the State of Israel – designed by Erich Mendelsohn, one of the giants of modern architecture – continues to garner interest around the world. In parallel with its reopening to the public, the international organization Iconic Houses chose to add Weizmann House to its ranks. This makes Weizmann House the first building in Israel to become a part of this network, joining such modern architectural wonders as Fallingwater, designed by Frank Lloyd Wright; Vila Tugentdat of Ludwig Mies van der Rohe; and another 150 houses around the world.

Israel is subjected to sand and dust storms from several directions: northeast from the Sahara, northwest from Saudi Arabia, and southwest from the desert regions of Syria. The airborne dust carried in these storms affects the health of people and ecosystems alike. New research at the Weizmann Institute of Science suggests that part of the effect might not be in the particles of dust but rather in bacteria that cling to them, traveling many kilometers in the air with the storms. Some of these bacteria might be pathogenic – harmful to us or the environment – and a few of them also carry genes for antibiotic resistance.

Gihon Spring, just downhill from the ancient city of Jerusalem, was crucial to the survival of its inhabitants, and archaeologists had uncovered the remains of a massive stone tower built to guard this vital water supply. Based on pottery and other regional findings, the archaeologists had originally assigned it a date of 1,700 BCE. But new research conducted at the Weizmann Institute of Science provides conclusive evidence that the stones at the base of the tower were laid nearly 1,000 years later.

More than 400 years after Galileo turned his telescope toward the planet Jupiter, the clouds and mist covering this giant of our Solar System are beginning to disperse. Since 1973, no fewer than six spacecraft have flown by Jupiter. But the Juno probe, launched in 2011 and in orbit around the planet since July 2016, is the first one equipped with systems that are able to reveal the secrets of Jupiter’s inner structure beneath the thick clouds.

Bread occupies a unique place in our diet: it accounts for about one-tenth of the calories many people in the West consume and up to 40 percent of the caloric consumption in some non-Western countries – more than any other food product. In the past few decades, since white bread has acquired a bad name, bakeries have been going out of their way to produce high-quality whole grain breads. But a new study conducted at the Weizmann Institute of Science and published recently in Cell Metabolism reveals that these “wholesome” choices are not necessarily the healthiest for everyone.
