    Science Tips, November 2013

    Three updates from the Weizmann Institute: international collaboration produces a new picture of the 3D structure of chromosomes; the world's smallest SQUID – used to measure magnetic fields – breaks the world record for sensitivity and resolution; mysterious microglia cells are shown to play critical roles in brain disease and health.

  • Science Tips, March 2013

    Three updates from the Weizmann Institute: scientists take steps toward building a complete, functional, artificial cell; progress is made toward understanding the measurement process in quantum systems; and a new study may help develop ways to control tissue destruction that results from inflammation and necrosis.

    America 2025: Precision Rx

    Prof. Ehud Shapiro, who created nano-sized computers that may someday circulate throughout the body diagnosing and treating diseases, is one of the researchers moving medicine into a new DNA age.

    Israel's ‘Pre-Nobel' Wolf Prize Awardees Announced

    The Institute's Prof. Joseph Imry has won the 2016 Wolf Prize in physics, deemed a strong indicator of winning the Nobel Prize. As <em>The Times of Israel</em> states, Prof. Imry is ""considered the ‘founding father' of mesoscopic physics,"" the study of objects so small they're invisible to the naked eye; thus, he laid the foundation for the crucial field of nanoscience.

    Nanostructures Made in Solar Furnace Using Sunlight

    As <em>The Jerusalem Post</em> reports, a group of scientists, including Weizmann's Prof. Reshef Tenne and his team, have created a new type of ""misfit"" nanostructure. The scientists created a sort of ""solar furnace"" made of ""highly concentrated solar radiation"" to produce the miniscule molecular ""closed-cage"" nanostructures, which have unique properties.

    Self Assembling Nanoparticles Could Lead to Rewritable Paper

    Dr. Rafal Klajn has developed a method for coaxing nanoparticles to self-assemble by focusing on the medium in which they are suspended. <em>The Engineer</em> reports that possible applications include rewritable paper, which uses dyes that respond to UV light, rather than ink; water decontamination; and controlled drug delivery.

  • Scientific Method

    Prof. Mordehai Heiblum has demonstrated a previously unseen and surprising phenomenon: electrons from different sources can interfere with each other without ever interacting.

    Self-Organization Makes for Efficient Separation

    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.

    Microscopic Cocoons Made of Silk Protein May Facilitate Drug Design

    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.
