If the observations are confirmed, it would be a first for Europe; so far, the top quark particle has only been generated by one lab in the US.

Time in space has always been an elusive issue for scientists who have long struggled to find a constant standard. But a new discovery may help us understand time as never before. Space.com reports that scientists are now using pulsars — rapidly spinning stars that pulse over time — to tell the universe’s time. This is due to a recent revelation about how pulsars function and rotate. A pulsar is a rotating neutron star that emits a beam of electromagnetic radiation.

- Scientists manage to teleport information nearly 10 miles with unprecedented precision. - The team used quantum entanglement to teleport the information. - The feat could lead to a global, impenetrable communication network and powerful quantum computers. Scotty won't beam anybody anywhere anytime soon, but a new report by Chinese scientists shows that it is possible to transmit information over long distances using quantum entanglement.

Is Time Disappearing from the Universe? (A Weekend Feature) Is Time Disappearing from the Universe? (A Weekend Feature) Scientists previously have measured the light from distant exploding stars to show that the universe is expanding at an accelerating rate. They assumed that these supernovae are spreading apart faster as the universe ages. Physicists also assumed that a kind of anti-gravitational force must be driving the galaxies apart, and started to call this unidentified force "dark energy".
Beginners Guide to Aerodynamics At this Web site you can study aerodynamics at your own pace and to your own level of interest. Some of the topics included are: Newton's basic equations of motion; the motion of a free falling object, that neglects the effects of aerodynamics; the terminal velocity of a falling object subject to both weight and air resistance; the three forces (lift, drag, and weight) that act on a glider; and finally, the four forces that act on a powered airplane. Because aerodynamics involves both the motion of the object and the reaction of the air, there are several pages devoted to basic gas properties and how those properties change through the atmosphere. This site was created at NASA Glenn as part of the Learning Technologies Project (LTP). It is currently supported by the Aeronautics Research Mission Directorate at NASA HQ through the Educational Programs Office at NASA Glenn.
