    Spare Parts Might “Jump-Start” Protein Design

    The idea of proteins that can be designed on computers for specific functions has been a cutting-edge concept that has stubbornly remained “in the future.” New research at the Weizmann Institute of Science may bring that future a bit closer. By going back to nature’s drawing board – evolution – the scientists have created new proteins, based on “existing natural parts,” that carry out their intended function with flying colors. These findings were reported in the Proceedings of the National Academy of Sciences (PNAS).

    Silk Micro-Cocoons Will Transport Proteins in Food, Drugs

    Scientists from Israel and abroad have designed microscopic silk capsules that can serve as a protective environment for the transport of fragile protein “cargo” for cosmetic, food and pharmaceutical applications — particularly the delivery of drugs within the body. The collaborative research, 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, was reported in Nature Communications on July 19.

    How Malaria Tricks the Immune System

    Global efforts to eradicate malaria are crucially dependent on scientists’ ability to outsmart the malaria parasite. And Plasmodium falciparum is notoriously clever: it is quick to develop resistance against medications and has such a complex life cycle that blocking it effectively with a vaccine has thus far proved elusive. In a new study reported in Nature Communications, researchers at the Weizmann Institute of Science, together with collaborators in Ireland and Australia, have shown that P. falciparum is even more devious than previously thought: not only does it hide from the body’s immune defenses, it employs an active strategy to deceive the immune system.
