How does Lene Hau slow down a beam of light? Hau and her team have previously shown that a Bose-Einstein condensate — which they make here by cooling sodium atoms to about 600 billionths of a degree (colder than deep space) — can slow down a light beam and even bring it to a standstill. […]
What happens to the air pressure inside a balloon when the balloon is squeezed to half its volume at a constant temperature?
What happens to the air pressure inside a balloon when the balloon is squeezed to half its volume at a constant temperature? What happens to the air pressure inside a balloon when it is squeezed to half its volume at constant temperature? The atmospheric pressure decreases as they rise, so they expand. What causes pressure […]

What is an autocrine factor?
What is an autocrine factor? The ability of cancer cells to produce and to respond to their own growth factors (autocrine secretion) has become a central concept linking oncogene and growth factor research. Antagonists of positive autocrine growth factors can inhibit growth of cancer cells in experimental animals. What is the purpose of autocrine signaling? […]
