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... view more (2001-01-25)

Ancient neutrinos could put string theory and quantum loop gravity to the test
Tiny but ageing neutrinos can be used to test the very foundations of quantum theory at unprecedented cosmological time scales.   view more (2005-10-14)

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.... view more (2004-04-13)

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... 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... 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... view more (2003-09-26)

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)

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)

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... view more (2002-04-26)

Glasgow astronomers explain hot star disks
Astronomers have been puzzled for decades as to how the rings of hot gas surrounding certain types of star are formed. Now a team of scientists from the Universities of Glasgow and Wisconsin believe they have found the answer. The team studied a type of young, hot star, known as a "Be star", that... view more (2002-11-01)

Astronaut health on moon may depend on good dusting
Lunar dust could be more than a housekeeping issue for astronauts who visit the moon. Their good health may depend on the amount of exposure they have to the tiny particles.   view more (2008-05-14)

'Rocket Science' to help Britain's elderly
Helping an elderly person up the stairs may not seem rocket science - but look again, perhaps it is. Scientists studying the effects of space flight on humans are applying their findings to the elderly population on earth after discovering that the effects of micro-gravity on astronauts are greatly... view more (2004-01-09)

Pulsar find boosts hope for gravity-wave hunters
Neutron star pairs may merge and give off a burst of gravity waves about six times more often than previously thought, scientists report in today's issue of the journal Nature [4 December]. If so, the current generation of gravity-wave detectors might be able to register such an event every year or... view more (2003-12-02)

Dark energy may be vacuum
Researchers at the University of Copenhagen's Dark Cosmology Centre at the Niels Bohr Institute have brought us one step closer to understanding what the universe is made of. As part of the international collaboration ESSENCE they have observed distant supernovae (exploding stars), some of which... view more (2007-01-17)

Lisa And The Search For Elusive Gravity Waves
For almost 100 years, scientists have been searching for direct evidence of the existence of gravity waves - faint ripples in the fabric of spacetime predicted in Albert Einstein's theory of General Relativity.   view more (2005-03-31)

Rivers on Titan, one of Saturn's moons, resemble those on Earth
Recent evidence from the Huygens Probe of the Cassini Mission suggests that Titan, the largest moon orbiting Saturn, is a world where rivers of liquid methane sculpt channels in continents of ice.   view more (2005-12-06)

Simulation Reveals How Body Repairs Balance
Your body goes to a lot of trouble to make sure you stay upright. But when the brain's neural pathways are impaired through injury, age or illness, muscles are deprived of the detailed sensory information they need to perform the constant yet delicate balancing act required for normal movement and... view more (2007-09-26)

Researchers find a potential key to human immune suppression in space
Researchers at the San Francisco VA Medical Center have identified a set of key immune-response genes that do not turn on in a weightless environment. The discovery is another clue in the effort to solve an almost 40-year-old mystery: why the human immune system does not function well in the... view more (2005-10-13)

Rosetta closes in on Earth - a second time
ESA's comet chaser, Rosetta, is on its way to its second close encounter with Earth on 13 November. The spacecraft's operators are leaving no stones unturned to make sure Earth's gravity gives it the exact boost it needs en route to its destination.   view more (2007-11-09)
