Grid computing ‘Mappa mundi’ unveiled in Florida

Visitors to Supercomputing ’06 in Tampa, Florida this week will be the first to see a new interactive map that shows nine of the world’s largest computing Grids. The map, developed by researchers from GridPP in the UK and the European particle physics laboratory, CERN, in Geneva, uses Google Earth to pinpoint Grid sites on six continents, showing more than 300 sites overall. Like the medieval ‘mappa mundi’, which showed what was known of the world at the time, this is one of the first attempts to show the whole scientific Grid world.

Colorectal Cancer :: New vaccine stimulates colorectal cancer patient’s immune systems to fight cancerous cells

British researchers have developed a vaccine that stimulates colorectal cancer patients’ immune systems to fight cancerous cells.

Heart Disease :: Stent wars ease into stent discussions

Acrimonious debate over the use of bare metal stents (BMS) versus drug-eluting stents (DES) is ending. Four new studies presented during a Monday news conference are quickly turning what had been open warfare between BMS and DES advocates into more measured discussions.

Heart Disease :: PCI for occlusion after MI not always beneficial

Logic would hold that an occluded infarct-related artery should be open before the patient is discharged. But the chair of the Occluded Artery Trial (OAT) presented data here showing that stable patients undergoing routine PCI for occluded arteries three to 28 days after MI had virtually the same number of major cardiovascular events as similar patients receiving medication alone.

Brain :: Speak, memory – Research challenges theory of memory storage

During sleep, freshly minted memories move from the hippocampus, part of the “old” brain, to the neocortex, or “new” brain, for long-term storage. This has been the reigning theory for decades. Brown University research provides the strongest proof yet of this interaction between the old and new brains — and offers surprising evidence that challenges critical details of this theory of learning and memory. Results appear in Nature Neuroscience.

First Far Eastern leopard captured in southeast Russia by international team

Just three days after catching a Siberian tiger in the Russian Far East, an international team led by biologists from the Wildlife Conservation Society captured another species last week that carries the dubious distinction of being the world’s most endangered big cat: an extremely Far Eastern leopard.

Stem Cell :: Repairing damage from heart failure using stem cells

Fiona See, Ph.D., postdoctoral research fellow in the laboratory of Dr. Silviu Itescu, M.B., B.S., will present two groundbreaking abstracts on repairing damage from heart failure with stem cells at AHA this year.

Heart Transplant :: Genes influence heart transplant rejection

Mario Deng, MD, assistant professor of Medicine in the division of Cardiology and director of the Cardiac Transplantation Research at Columbia University Medical Center, will present his laboratory’s research on the relationship between genes and the rejection of transplanted hearts.

Gene :: Wielding the subtle weapons of a fungus

An international group of researchers has identified genes which enable the maize smut pathogen to live as a parasite.

Mayo Clinic research reveals ‘broken heart syndrome’ recurs in 1 of 10 patients

In the largest review of “broken heart syndrome” patients ever conducted, Mayo Clinic researchers studied 100 patients and found symptoms recurred in 1 out of 10 patients over a four-year period, and that patients experiencing physical stress had a worse survival rate than those under emotional stress.
