Friction almost vanishes in microscale graphite
Scientists investigate how ice melts below freezing due to nanowire's pressure
How stick insects honed friction to grip without sticking
When they're not hanging upside down, stick insects don't need to stick. In fact, when moving upright, sticking would be a hindrance: so much extra effort required to 'unstick' again with every step.
Chaos theory helps to predict the outcome at the roulette table
At first glance, a roulette table looks like a jumble of numbers and a randomly hopping little white ball. But with a better understanding of physics and some general knowledge of the starting conditions, it ...
Materials scientist creates world's toughest fiber by adding slip knot
New observations of a 'dust trap' around a young star solve long-standing planet formation mystery
Astronomers using the new Atacama Large Millimeter/submillimeter Array have imaged a region around a young star where dust particles can grow by clumping together. This is the first time that such a dust ...
Giant ice avalanches on Saturn's moon Iapetus provide clue to extreme slippage elsewhere in solar system
Saturn's ice moon Iapetus has more giant landslides than any solar system body other than Mars. Measurements of the avalanches suggest that some mechanism lowered their coefficients of friction so that they ...
Increasing rainfall may affect winds: study
Earthquakes generate big heat in super-small areas: study
Most earthquakes that are seen, heard, and felt around the world are caused by fast slip on faults. While the earthquake rupture itself can travel on a fault as fast as the speed of sound or better, the fault ...
Stronger than steel, novel metals are moldable as plastic
(PhysOrg.com) -- Imagine a material that's stronger than steel, but just as versatile as plastic, able to take on a seemingly endless variety of forms. For decades, materials scientists have been trying to ...
Racing cars on walls would be possible, according to student paper
Driving a racing car at an angle of 90 degrees to the ground could be possible with the right track design, suggest University of Leicester students
Friction research casts doubt on fundamental physics law
Glasperlenspiel: Scientists propose new test for gravity
A new experiment proposed* by physicists at the National Institute of Standards and Technology may allow researchers to test the effects of gravity with unprecedented precision at very short distances -- a ...
