New Breast Cancer Test Could Save Lives

...s disease. The test, which utilises an innovative radar system, will enable women to be tested regularly without the fear of over-exposure to radiation, a problem with existing X-ray tests. Currently, in order to detect cancer at an early stage ?which is extremely important for successful treatment - many...

Nanoscale Diagnostic Sets Sights on Alzheimer's

... are many biomarkers for disease that go under the radar of conventional diagnostic tools. The extraordinary sensitivity of the bar code assay has a chance to change the way the medical community thinks about molecular diagnostics and the markers they consider for many types of diseases." ?Chad Mirkin, Nor...

Scripps research scientists identify infertility molecule

...mans. "This is a receptor that wasn't on anyone's radar screen from a fertility standpoint," says Jerold Chun, M.D., Ph.D., who conducted the study with his research associate Xiaoqin Ye, M.D., Ph.D., and their colleagues at The University of Tokyo, Washington State University, and the Fred Hutchinson Can...

Compound might defeat African sleeping sickness, clinical trial beginning this month

... developing countries often fly beneath the profit radar of large pharmaceutical companies," Tidwell said. "That's because large companies require a high return on their investments, which means they don't have sufficient incentives to develop low-cost drugs. Despite being one of Africa's most prevalent an...

The synapse is a shotgun

...said Sejnowski. "There's just nothing solid on our radar screen right now," he said. "There is speculation that ectopic release represents some sort of spillover that neurons use under certain circumstances. Or, it may be an alternative mode of neurotransmission that neurons use at different points in thei...

Boosting newborns' immune responses

...rtain white blood cells. Functioning like an early radar system, TLRs detect the presence of invading bacteria and viruses and trigger production of "danger signals" ?proteins known as cytokines that trigger other immune cells to mount a defense against the infection. People have 10 different kinds of TLRs...

Researchers develop portable 'vein finder' for faster, more accurate injections

...g wavelengths and frequency. For example, a police radar gun sends microwave signals to a moving car, and when signals bounce back, the change in their frequency provides a measurement used to determine the vehicle's speed. Doppler ultrasound is similar, except that acoustical waves are transmitted. Comp...

Bats prey on nocturnally migrating songbirds

...mmal, equipped with sharp canines and an efficient radar system which remains probably largely inaudible to songbirds. In 2001, Carlos Ibáñez and his colleagues at the Doñana Biological Station in Seville, Spain, suggested that the giant noctule bat (Nyctalus lasiopterus), a rare European species occur...

Breakthrough developments in rheumatoid arthritis reported

...Ps, to identify players that have fallen under the radar of older methods. The group has discovered another signaling molecule that seems to increase a person’s risk for rheumatoid arthritis by 30 percent. (The paper reporting the gene is in press.) In collaborations with other scientists worldwide, D...
