Findings could lead to new understanding of diabetes, Crohn’s, and more
Researchers at Joslin Diabetes Center, Harvard Medical School, and other institutions have identified the function of a protein, dubbed aire, that is critical to helping immune cells learn to recognize–and avoid attacking–the far-flung organs and tissues of the body. The protein appears to work by turning on in the thymus, which lies beneath the breast bone, the production of a wide array of proteins from the bo
An early version of a new software system developed by University at Buffalo researchers that detects cyberattacks while they are in progress by drawing highly personalized profiles of users has proven successful 94 percent of the time in simulated attacks.
The “user-level anomaly detection system” was described here today (Oct. 10, 2002) at the military communications conference known as MILCOM 2002.
“We have developed a new paradigm, proactively encapsulating user intent where y
The first complete map of drug related web-sites on the Internet is under construction. Dr Fabrizio Schifano and colleagues at St George`s Hospital Medical School in Tooting, London, will collect and analyse data from web-sites relating to the design and sale of recreational and illicit substances. The purpose is to provide healthcare professionals in the European community with as much information as possible on the latest drugs – drugs that are often unrecorded in medical textbooks.

A partially exploding star, known as a nova, has recovered more quickly than expected, say scientists who have analysed new data from the ESA`s XMM-Newton X-ray satellite.
Nova explosions are not completely destructive phenomena. In fact, after an explosion occurs, the star recovers and starts shining again. Until now, astronomers have not known how long this process takes. In this case, however, the exploding star recovered in less than three years. This is surprising, given the fact that t
Perhaps, bioterrorists will not be able to spread lethal bacteria of anthrax in envelopes all over the world. Siberian biologists and physics have thought up how to adapt electron accelerator that is usually used for sterilizing medical equipment for decontamination of letters. To optimize the power of the accelerator they calculated how many bacteria could get into a human body when touching the letter infected and how many bacteria should be destroyed to avoid the tragedy.
For their experi
Genomes of multicellular organisms are one of the greatest mysteries of biology. The more is discovered about them, the more questions are to be answered. One of such questions is connected with the size of a genome. As is known since the middle of the 20th century, the level of organization of an organism does not depend on the genome size, i.e., on the amount of DNA in the nucleus of a cell. Sometimes, a primitive organism contains much more DNA than a mammal. For example, the genome of certain amo
