A unique microchip with microscopic nail structures enable close communication between the electronics and biological cells. The new chip is a mass-producible, easy-to-use tool in electrophysiology research, for example for fundamental research on the functioning and dysfunctioning of the brain. Each micronail structure serves as a close contact-point for one cell, and contains an electrode [...]

Peering through the thick dust clouds of our galaxy’s “bulge” (the myriads of stars surrounding its center), astronomers have unveiled an unusual mix of stars in the stellar grouping known as Terzan 5. Never observed anywhere in the bulge before, this peculiar “cocktail” of stars suggests that Terzan 5 is in fact one of the [...]

When cells are confronted with an invading virus or bacteria or exposed to an irritating chemical, they protect themselves by going off their DNA recipe and inserting the wrong amino acid into new proteins to defend them against damage, scientists have discovered. These “regulated errors” comprise a novel non-genetic mechanism by which cells can rapidly [...]

Researchers have developed a technique for fabricating 3-D, single-crystalline silicon structures from thin films by coupling photolithography and a self-folding process driven by capillary interactions.
Two signaling pathways essential to normal human development — the Wnt/Wingless and epidermal growth factor receptor pathways — interact in ways that can promote tumor cell invasion and metastasis, researchers reported.
For rescuers working in remote places working phones and Internet are literally a question of life and death. A team of researchers and businesses in Norway, Spain and Finland decided they need to be equipped with a box with the power to connect them to networks wherever they are.
Angst could be more than a rite of passage for insecure teenagers, according to a new study. Researchers have discovered that insecure adolescents experience more intense pain in the form of frequent headaches, abdominal pain and joint pain. These teens are also more likely to be depressed than peers with secure attachments.
