...tes are reporting development of the first test to detect
a potential biomarker for human exposure to diesel exhaust, a major source of environmental pollution that is classified as a probable human carcinogen. In an article scheduled for the current (July 16) issue of ACSs Chemical Research in Toxicolog...
Geisinger scientist seeks cure for Lou Gehrig's disease, creating device to find treatment

Carnegie Mellon scientists find key HIV protein makes cell membranes bend more easily
...on. The Carnegie Mellon scientists used X-rays to detect
the effect of FP-23 on lipid bilayers that mimic cell membranes. Lipid bilayers form different phases that change with temperature, but the fluid phase is the most biologically relevant. Using X-ray diffuse scattering, the team quantified structural ...

Scientists discover new way to study nanostructures
...overed that the AC Josephson effect can be used to detect
mechanical motion of atoms placed in the Josephson... "We show here that in addition to being able to detect
the effects of electromagnetic radiation on the AC Josephson current, one can also use it to probe m...
Molecular detectors may refine cancer treatment

... in the physician office laboratory. The BChip can detect
two influenza B virus strains (B/Victoria/2/87 and B/Yamagata/16/88), which are critical in determining seasonal influenza vaccines. In a recent study of 62 influenza B virus samples from 19 countries, dating from 1945 to 2005, as well as five ne...

Gene discovered for type 1 diabetes in children
...ely with relatively rare gene variants, we can now detect
common genetic variants that are important in large numbers of individuals, and begin to understand how multiple genes interact in complex diseases such as diabetes. In the discovery phase of the study, the investigators examined the genomes of 1,...
