Breaking research from science, medicine and technology.

Researchers have revealed that neurons can utilize a supremely localized internal store of calcium to initiate the secretion of neuropeptides, one class of signaling molecules through which neurons communicate with each other and with other cells. …read more Source: EurekAlert

Researchers at Albert Einstein College of Medicine of Yeshiva University have discovered a signaling pathway in cancer cells that controls their ability to invade nearby tissues in a finely orchestrated manner. The findings offer insights into the early molecular events involved in metastasis, the deadly …

Cells have their own tiny skeletons that are responsible for many important cellular functions. EPFL scientists have developed novel fluorescent probes for imaging these important structures easily and with unprecedented resolution. …read more Source: EurekAlert

Soils that formed on the Earth’s surface thousands of years ago and that are now deeply buried features of vanished landscapes have been found to be rich in carbon, adding a new dimension to our planet’s carbon cycle. …read more Source: EurekAlert

Using molecules of DNA like an architectural scaffold, Arizona State University scientists, in collaboration with colleagues at the University of Michigan, have developed a 3-D artificial enzyme cascade that mimics an important biochemical pathway that could prove important for future biomedical and energy applications. …read …

Researchers at the University of California, San Diego School of Medicine have identified a mutated gene common to adenosquamous carcinoma tumors — the first known unique molecular signature for this rare, but particularly virulent, form of pancreatic cancer. …read more Source: EurekAlert
