In 2002, Secretary of state Donald Rumsfeld made a statement regarding weapons of mass destruction that today is still well known. He famously parsed the evidence (or lack thereof) into "known knowns, known unknowns, and unknown unknowns." ...

Researchers have uncovered the secret recipe to making some petunias such a rare shade of blue. The findings may help to explain and manipulate the color of other ornamental flowers, not to mention the taste of fruits and wine, say ...
Restricting calorie consumption is one of the few proven ways to combat aging. Though the underlying mechanism is unknown, calorie restriction has been shown to prolong lifespan in yeast, worms, flies, monkeys, and, in some studies, humans. ...

Roughly 40 percent of all medications act on cells' G protein-coupled receptors (GPCRs). One of these receptors, beta 2 adrenergic receptor site (B2AR), naturally transforms between two base configurations; knowing the precise location of ...

What is a Load Cell? A load cell is a transducer that is used to changes a force into an electrical signal or into any other signal. This conversion is taken place in two stages. Through a mechanical arrangement, the force being sensed ...

Researchers have used one of the brightest X-ray sources on the planet to map the 3-D structure of an important cellular gatekeeper known as a G protein-coupled receptor, or GPCR, in a more natural state than possible before. The new ...
Apple said Tuesday it had no "backdoor" in its products after a security researcher and a leaked document suggested the US National Security Agency had unfettered access to the iPhone. Apple said in an email to AFP that it "has never ...
