Gravity detector spots underground hideaways
A new way of detecting underground bunkers or hideaways - called gravity gradiometry - is announced today in the Institute of Physics journal, Journal of Physics D: Applied Physics. Gravity gradiometry detects differences in the Earth's gravitational attraction caused by hollows in the ground where underground stores or tunnels lie. Ways of... view more... (2001-01-25)

Physiological Effects of Reduced Gravity on Bacteria
An article in Journal of Applied Microbiology investigates how bacteria respond when they are subjected to environmental alterations, such as those of space stations, which feature lowered effects of gravity. view more (2005-03-10)
Artificial gravity: the next small step?
Dr Kevin Fong will talk about artificial gravity, one of the latest technologies being considered for human missions to Mars, in an event organised by the Royal Institution on 11 May 2004. The latest results from the Mars Rovers are impressive but the red planet will not yield its secrets easily. Investigation of the existence of Martian life,... view more... (2004-04-13)
Big and small dents
The Earth explorer satellite GOCE (Gravity Field and Steady-State Ocean Circulation Explorer), built by the European Space Agency ESA, was successfully launched today at 15:21 GMT from the Russian Cosmodrome Plesetsk. GOCE is the first satellite mission within the framework of the Living Planet Programme of ESA and will map Earth's gravity field... view more... (2009-03-18)
ESA to look for the missing link in gravity
Although you can never be certain of predicting future developments in science, there is a good chance of a fundamental breakthrough in physics soon. With a series of unique experiments and missions designed to test our understanding of gravity, the European Space Agency (ESA) hopes to get to the very bottom of it. Scientists will study space... view more... (2002-09-11)
National Physical Laboratory Stages Unique On-Line Experiments
Does your computer’s clock always run slow? How good are human beings at estimating? How much does gravity vary over the globe? With your help we are attempting to find answers to these questions as part of a huge on-line Web event to celebrate World Metrology Day 2001, Sunday 20th May. This is the first time NPL have attempted such a... view more... (2001-05-18)
Paramecia Adapt Their Swimming to Changing Gravitational Force
For many single-celled organisms living in water, the force is always against them. The classic example is the slipper-shaped paramecium, which consistently swims harder going up than going down, just to keep from sinking. view more (2006-09-19)
ZARM Drop Tower becomes ESA External Facility
The European Space Agency is to declare the "Zentrum für Angewandte Raumfahrt Microgravitation" ZARM Drop Tower in Bremen an ESA External Facility. This prestigious title will be conferred at a ceremony at ZARM on 2 October, beginning at 12:45, attended by the Mayor of Bremen and President of the City Senate Dr Henning Scherf,... view more...

Vanquishing infinity
Quantum mechanics and Einstein's theory of general relativity are both extremely accurate theories of how the universe works, but all attempts to combine the two into a unified theory have ended in failure. view more (2009-08-18)
Precise Radio-Telescope Measurements Advance Frontier Gravitational Physics
Scientists using a continent-wide array of radio telescopes have made an extremely precise measurement of the curvature of space caused by the Sun's gravity, and their technique promises a major contribution to a frontier area of basic physics. view more (2009-09-02)
Remnants of ice age linger in gravity
Researchers have uncovered a large area of low but increasing gravity over North America - the lingering effect of the last ice age when sheets of ice sometimes three kilometres thick covered nearly all of Canada and the northeastern U.S. view more (2007-05-11)
NASA finds direct proof of dark matter
Dark matter and normal matter have been wrenched apart by the tremendous collision of two large clusters of galaxies. The discovery, using NASA's Chandra X-ray Observatory and other telescopes, gives direct evidence for the existence of dark matter. view more (2006-08-22)
U of M study examines kidney stone prevention in astronauts
As the space shuttle Discovery prepares to launch on July 1, researchers at the University of Minnesota have identified a way for astronauts to reduce their risk of developing kidney stones while in space. view more (2006-06-28)
March launch planned for ESA's gravity mission
ESA is now gearing up to return to Russia to oversee preparations for the launch of its GOCE satellite - now envisaged for launch on 16 March 2009. view more (2009-02-05)
Spread of plant diseases by insects can be described by equations that model interplanetary gravity
Researchers from Penn State University and the University of Virginia show that the spread of diseases by insects can be described by equations similar to those that describe the force of gravity between planetary objects. view more (2006-09-05)
Engineer: Head-first slide is quicker
Base running and base stealing would appear to be arts driven solely by a runner's speed, but there's more than mere gristle, bone and lung power to this facet of baseball - lots of mathematics and physics are at play. view more (2008-09-29)
Penn State Researchers Look Beyond the Birth of the Universe
According to Einstein's general theory of relativity, the Big Bang represents The Beginning, the grand event at which not only matter but space-time itself was born. view more (2006-05-15)
Physicists say universe evolution favored three and seven dimensions
Physicists who work with a concept called string theory envision our universe as an eerie place with at least nine spatial dimensions, six of them hidden from us, perhaps curled up in some way so they are undetectable. view more (2005-09-29)
ESA finds a black-hole flywheel in the Milky Way
Far away among the stars, in the Ara constellation of the southern sky, a small black hole is whirling space around it. If you tried to stay still in its vicinity, you couldn`t. You`d be dragged around at high speed as if you were riding on a giant flywheel. In reality, gas falling into the black hole is whirled in that way. It radiates energy,... view more... (2002-04-26)
