The great gravity showdown
During the week of February 6-10, 2012, some extremely weighty matters were in progress at NISTs non-magnetic facility, where PML researchers hosted an international gravimeter shoot-out with potentially ...
In the early universe, rapid expansion or something very weird
(PhysOrg.com) -- The widely-accepted theory of cosmic inflation states that our universe expanded rapidly in the moments after its birth, resulting in the immense expanse we see today.
Researchers create first large-scale model of human mobility that incorporates human nature
For more than half a century, many social scientists and urban geographers interested in modeling the movement of people and goods between cities, states or countries have relied on a statistical formula called ...
Glenn chats with space station to mark anniversary
(AP) -- NASA surprised John Glenn with the kind of anniversary gift only a space agency can give, enabling him to speak live with the International Space Station on Monday as he marked 50 years since his ...
Martian carbon dioxide clouds tied to atmospheric gravity waves
On 4 March 1997 the Mars Pathfinder lander fell through the thin Martian atmosphere. During its descent, instrumentation aboard the lander recorded the changing atmospheric temperature, pressure, and density.
Rapunzel, Leonardo and the physics of the ponytail
(PhysOrg.com) -- New research provides the first mathematical understanding of the shape of a ponytail and could have implications for the textile industry, computer animation and personal care products.
NASA showcases ‘spinoff’ technologies
Contrary to popular belief, Tang, Velcro and Teflon (along with the zero-gravity space pen) arent derived from NASA technology. NASA has, however, developed numerous technologies over the ...
Google Earth ocean terrain receives major update
Internet information giant Google updated ocean data in its Google Earth application this week, reflecting new bathymetry data assembled by Scripps Institution of Oceanography, UC San Diego, NOAA researchers and many other ...
Repulsive gravity as an alternative to dark energy (Part 2: In the quantum vacuum)
Weightlessness weighs heavy on genes -- a fly's perspective
On Earth all biology is subjected to gravity. Some biological systems require gravity for correct orientation (geotropism: plants grow up, roots grow down). In the absence of gravity even human biology is affected: astronauts ...
Repulsive gravity as an alternative to dark energy (Part 1: In voids)
Does antimatter weigh more than matter? Lab experiment to find out the answer
Does antimatter behave differently in gravity than matter? Physicists at the University of California, Riverside have set out to determine the answer. Should they find it, it could explain why the universe ...
Students rename NASA moon probes Ebb and Flow
A pair of unmanned NASA spacecraft that are orbiting the Moon were renamed Ebb and Flow on Tuesday by a middle school class in Montana, the US space agency announced.
