Researchers in the Baxter Laboratory at Stanford University Medical Center have published new evidence showing that cells from the bone marrow might help repair or maintain cells in other tissues. In a paper in this weeks online edition of the Proceedings of the National Academy of Sciences, the researchers describe finding chromosomes from a bone marrow transplant in the brain cells of transplant recipients.
When people receive a bone marrow transplant after high-dose chemotherapy, s
A team of network security experts in California has determined that the computer worm that attacked and hobbled the global Internet eleven days ago was the fastest computer worm ever recorded. In a technical paper released today, the experts report that the speed and nature of the Sapphire worm (also called Slammer) represent significant and worrisome milestones in the evolution of computer worms.

A major computer project has been launched today to analyse millions of different chemicals in the search for drugs to combat the bioterrorist threat of smallpox.
The smallpox research project will use the ‘screensaver downtime’ donated by up to two million computer users worldwide to screen 35 million compounds and identify those most likely to be suitable for drug development.
Currently no drugs are available to combat the smallpox virus after infection, and the only prevention i
Diabetes is a widespread illness affecting 5 per cent of the population. In diabetics the metabolism produces an excess of glucose in the blood and, as a result, a number of sufferers need doses of insulin which allows them to regulate their glucose levels.
Currently, the method of administering insulin to diabetic patients making use of emergency services for insulin dosage depends on the experience of the qualified personnel. That is, the same patient can receive different insulin doses,
The use of combinations of antiretroviral drugs including nucleoside analogs, protease inhibitors (PIs) and reverse transcriptase inhibitors – collectively termed highly active anti-retroviral therapy (HAART) – has resulted in a dramatic improvement in health status for a large number of HIV-infected individuals.
Side effects in many users, however, cause non-adherence to treatment regimes and concern over their long-term use in the management of chronic HIV infection. The adverse effects o
Groundbreaking research released on the economics of marine protected areas
For the first time anywhere, the analysis of leading economists and ecologists worldwide has been brought together in one place, to examine the economics of Marine Protected Areas (MPAs). Two special issues of the international research journal Natural Resource Modeling (Vol. 15 Nos. 3 &4) have just been published, within which the editors, Ussif Rashid Sumaila (University of British Columbia) and Anthony Char
