About Us
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.
We often speak of electrons “flowing” through materials, but in fact, they do not normally move like a liquid. However, such “hydrodynamic” electron flow had long been predicted – and now, Weizmann Institute of Science physicists have managed, with the help of a unique technique, to image electrons flowing similarly to how water moves through a pipe. This is the first time such “liquid electron flow” has been visualized, and it has vital implications for future electronic devices.

The quantum computers of the future will be able to perform computations that cannot be done on today’s computers. These may likely include the ability to crack the encryption that is currently used for secure electronic transactions, as well as the means to efficiently solve unwieldy problems in which the number of possible solutions increases exponentially. Research in the quantum optics lab of Prof. Barak Dayan at the Weizmann Institute of Science may be bringing such computers one step closer by providing the “quantum gates” required for communication within and between such quantum computers.

Utrasound equipment has shrunk in both size and price in recent years – so much so that it is now standard in hospitals and clinics all over the world. But today’s ultrasound still requires a highly trained expert to acquire the image and interpret the results, and this has prevented its use in certain settings – for example, in urgent care. In a joint venture they call On-Sight, computer scientists at the Weizmann Institute of Science and a cardiologist at the New York University School of Medicine have teamed up to develop an automated system that guides the operator in acquiring the images and then accurately interprets the results for physicians. This venture was recently awarded first place in the third Echovation Challenge of the American Society of Echocardiography.

The three fresh Weizmann Institute of Science graduates – Drs. Yuval Gilad, Idan Alyagor, and Yoav Politi – named their company FREEZEM. As the name suggests, they are developing a way to cryogenically freeze the fly eggs so that they remain viable. The technology for freezing fly eggs, they say, is different from that used to freeze human ova or bacteria, and they are the first to offer this development.

When investigating atoms, scientists face a challenge: at room temperature, individual atoms in a gas have kinetic energy, and fly around at high velocities. Temperature is, in essence, the relative movement between atoms; thus, the goal of getting the atoms to have small relative velocities involves freezing them to extremely cold temperatures. Now, a group at the Weizmann Institute of Science has developed a new universal method for cooling ions.

It is said that a weak link determines the strength of the entire chain. Likewise, defects or small cracks in a solid material may ultimately determine the strength of that material – how well it will withstand various forces. For example, if force is exerted on a material containing a crack, large internal stresses will concentrate on a small region near the crack’s edge. When this happens, a failure process is initiated, and the material might begin to fail around the edge of the crack, which could then propagate, leading to the ultimate failure of the material.

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.

The tiny cone-shaped “skimmers” used in experiments looking for exotic chemical-quantum phenomena resemble the intake mechanisms of aircraft engines, and they perform similar functions: each directs the flow of gas – the engine intake controls the supply of air for burning fuel, and the “skimmer” creates beams of cold flying atoms or molecules. While skimmers have been a necessary component in atomic and molecular-beam experiments for decades, they were also known to impose a fundamental limit on the number of particles one could pack into the beam.

Separation technology is at the heart of water purification, sewage treatment, and materials reclamation, as well as numerous basic industrial processes. Membranes are used to separate out the smallest nanoscale particles, and even molecules and metal ions. Prof. Boris Rybtchinski and his group of the Weizmann Institute of Science’s Department of Organic Chemistry have developed a new type of membrane that could extend the life of a separation system, lower its cost and, in some cases, increase its efficiency as well.
