A new approach to providing medication for adult diabetics (type 2 diabetes) that is not dependent on insulin has been developed by a doctoral student at the Hebrew University of Jerusalem. For his work, which he did for his Ph.D. thesis in pharmacology, Arie Gruzman was awarded one of this year’s Kaye Innovation Awards at the Hebrew University.

Unlike other conventional drugs that require active insulin-producing cells in the pancreas and that often fail to overcome a companion problem of

The EU examines ways to reverse damage in the Mediterranean and Black Seas

Fifty years of intense development and exploitation have resulted in significant change to the fragile natural resources of the Mediterranean and Black Seas, and their coastal areas. Agreeing ways to prevent further environmental degradation will be the focus of the “International Conference on the Sustainable Development of the Mediterranean and Black Sea Environment” (IASON), to be held from 28 May to 1June i

Virologists at Jefferson Medical College may have discovered a new way by which HIV, the AIDS virus, can evade both anti-viral drugs and vaccines.

Researchers had reported last summer that a protein called CEM15 is a natural inhibitor of HIV, acting as a brake on HIV’s replication. They also showed that an HIV-encoded protein, Vif, or Virion infectivity factor, counteracts CEM15. Vif, in effect, is a shield to protect HIV from a host cell’s defenses.

But how CEM15 worked was somet

Researchers at Washington University School of Medicine in St. Louis have begun unraveling the network of genes and proteins that regulate the lives of cells. The investigators compared the genome of the yeast Saccharomyces cerevisiae (S. cerevisiae) to those of five other yeast species to identify all the locations at which molecules known as regulatory proteins attach to DNA to turn genes on and off. The study is published in the May 30 issue of the journal Science.

Among the many potenti

A new imaging technique that uses electron diffraction waves to improve both image resolution and sensitivity to small structures has been developed by scientists at the University of Illinois at Urbana-Champaign. The technique works on the same principle as X-ray diffraction, but can record structure from a single nanostructure or macromolecule.

Determining the structure of materials — such as protein crystals — is currently performed using X-ray diffraction. However, many small structur

The first detailed map of space within about 1,000 light years of Earth places the solar system in the middle of a large hole that pierces the plane of the galaxy, perhaps left by an exploding star one or two million years ago.

The new map, produced by University of California, Berkeley, and French astronomers, alters the reigning view of the solar neighborhood. In that picture, the sun lies in the middle of a hot bubble – a region of million-degree hydrogen gas with 100-1,000 times fewer
