    The Man Who Studies Deadly Diseases

    Israel21c profiles Dr. Ron Diskin, whose expertise in x-ray crystallography made him a key member of a groundbreaking Caltech-Rockefeller University team researching HIV. Now, as a new scientist at the Weizmann Institute, he is building a lab to advance his structural research on HIV and tropical Arena viruses that cause fatal diseases.

    Israel Start-Up Preparing for a Post-Antibiotics World

    Israeli startup BiomX, which is developing a treatment that selectively kills specific bacteria, last week completed a $24 million financing round. The company was founded in 2015 on the basis of research by two Weizmann Institute scientists: Dr. Eran Elinav, a specialist in microbiome – the mix of bacteria in the human body (he is also known from DayTwo, which developed an app for nutritional consultation according to a person's individual composition of bacteria), and Professor Rotem Sorek, an expert in genetic engineering and bacterial genetics. The third founder is MIT Professor Timothy K. Lu, who specializes in genetic engineering of anti-bacterial viruses.

    Cells Talk and Help One Another via Tiny Tube Networks

    When the physician and scientist Emil Lou was an oncology fellow at Memorial Sloan Kettering Cancer Center about a decade ago, he was regularly troubled by the sight of something small but unidentifiable in his cancer-cell cultures. Looking through the microscope, he said, he “kept finding these long, thin translucent lines,” about 50 nanometers wide and 150 to 200 microns long, extending between cells in the culture. He called on the world-class cell biologists in his building to explain these observations, but nobody was sure what they were looking at. Finally, after delving into the literature, Lou realized that the lines matched what Hans-Hermann Gerdes’ group at the University of Heidelberg had described as “nanotubular highways” or “tunneling nanotubes” (TNTs) in a 2004 paper in Science.
