A group of scientists at The Scripps Research Institute is reporting a discovery that sheds light on an area of research fundamental to everything from the normal processes that govern the everyday life of human cells to the aberrant mechanisms that underlie many diseases, including cancer and septic shock.

The discovery concerns tiny fragments of RNA known as microRNA and their relationship to the genetic transcripts known as messenger RNA (mRNA). All genes expressed in the

A new tumor-suppressor gene has been discovered by a team of researchers at Penn State, which also has discovered how the gene works with another tumor suppressor to control tissue growth. The team’s genetic and biochemical studies will be published in the 11 March 2005 issue of the journal Cell. “This discovery extends our understanding of how tissue growth is controlled both during normal development and during the formation of tumors, and it raises the possibility that the function of t

Black holes have a reputation for voraciously eating everything in their immediate neighborhood, but these large gravity wells also affect electromagnetic radiation and may hinder our ability to ever locate the center of the universe, according to an international research team.

“Any attempt to discover what was happening a long time ago at the beginning of our universe must take into account what gravitationally assisted negative refraction does to the radiation being viewed,” say

Terrier, a new cutting-edge software for the rapid development of web, intranet and desktop search engines, developed by researchers at the University of Glasgow, has all the prerequisites to become the European answer to Google.

This groundbreaking system from DCS utilises state-of-the-art web search technology. It offers a modular platform for the rapid development of large-scale Information Retrieval applications. Providing indexing and retrieval functionalities, Terrier comes wi

Students from Duke University’s Pratt School of Engineering are partnering with Carnegie Mellon University’s “Red Team” in an effort to win a $2 million prize from the Defense Advanced Research Projects Agency (DARPA). All they have to do is complete the toughest ground course ever devised for a self-guided robotic vehicle.

The contest, called the DARPA Grand Challenge, is a race between fully self-guided ground vehicles to be conducted in the Southwestern United States on Oct. 8,

Livermore scientists are working to solve a 50-year-old question: Can neutrinos – a particle that is relatively massless, has no electric charge yet is fundamental to the make-up of the universe – transform from one type to another?
Scientists are using two giant detectors, one at Fermi Lab and another in a historic iron mine in northern Minnesota, to work on the answer.

As part of the international team working on the Main Injector Neutrino Oscillation Search (MINOS) proj
