A new method to accurately measure quantities of a cheese-ripening enzyme in milk could reduce the time and cost of producing cheese, according to a report by Purdue University researchers.

Infrared spectroscopy was used in combination with statistical analysis to determine the concentration of plasminogen, a form of the enzyme integral to cheese manufacturing. The study, by co-authors Lisa Mauer and Kirby Hayes, both assistant professors in the Department of Food Science, is published in th

Scientists are using new imaging technology to help them perform “virtual biopsies,” – biological profiles of specific tumors that may help predict a patient’s response to treatment and probability of long-term survival. This whole new realm of imaging is called functional MRI (magnetic resonance imaging), a process that offers insight into a tumor’s character, not just its superficial structure.

Using functional MRI, Dr. Michael Knopp, a radiologist and a member of The Ohio State

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
