Discovery of ‘hot pepper’ receptor in heart may explain chest pain, lead to new treatments

The secret to heart attack chest pain may be on the tip of your tongue.
Although they may seem unlikely bedfellows, Penn State College of Medicine researchers found evidence to suggest that the same type of nerve receptors that register the burning sensation from hot peppers in the mouth may cause the sensation of chest pain from a heart attack.

“Our study is the first to demonstrat

Rensselaer Researchers Pioneer Interconnect Technology that May Take Chips Into 3-D

Researchers led by Ronald J. Gutmann in the Focus Center-New York at Rensselaer (FC-NY-RPI) are pioneering new interconnect technologies that promise to deliver smaller, faster, inexpensive, microelectronics and circuits that function in three dimensions.

Researchers at Rensselaer’s Focus Center-NY for Interconnections for Gigascale Integration believe that a strategy in which several chip wa

New agricultural crops stand a better chance of helping to fill the world’s bread baskets, says a University of Maine economist, if plant breeders take farmers’ needs into account early in the crop development process. A new research report by Timothy J. Dalton, assistant professor in the Dept. of Resource Economics and Policy, is one of the first to demonstrate farmers’ preferences using a quantitative approach.

Dalton’s research could help agricultural research organiz

Dendritic cells monitor foreign substances in the body and communicate whether they present a danger to the rest of the immune system. Emory immunologists have developed a sensitive method to detect and follow dendritic cells by marking them with a change in their DNA, and have discovered that they are more numerous and longer lived than other scientists had previously observed. Their research uses a gene gun, which shoots DNA into the skin using microscopic gold pellets, and could lead to a faster a

Sudden cardiac death from ventricular tachyarrhythmias is the leading cause of death in Europe and the US. It effects hundreds of thousands people each year. Many of them have known heart disease, mainly coronary artery disease. The implantable defibrillator (ICD) effectively treats such arrhythmias and prevents sudden cardiac death. Identification of patients at risk who may gain profit from prophylactic ICD implantation remains a difficult task for the cardiologist

Ecologists are taking to the trees in a bid to unravel the ecology of shell coiling in snails. Speaking at the British Ecological Society’s Annual Meeting, being held at Manchester Metropolitan University on 9-11 September 2003, Dr Paul Craze of the University of Plymouth will explain how examining the proportion of right- and left-coiling individuals in a species of Bornean tree snail could help ecologists understand how new species arise.

The vast majority of snail species are almost exclu
