Attoclock turns electrons into movie stars NewScientist Share    
An electron takes just billionths of a billionth of a second to escape its host molecule - mere attoseconds. Now we have the first snapshots of what is the initial step in almost every chemical reaction. Read the abstract of the forthcoming Physical Review Letters article. More
Graphene bubbles could make better lenses Physics World Share
A tiny bubble of graphene could be used to make an optical lens with an adjustable focal length. That is the claim of physicists in the U.K., who have shown that the curvature of such bubbles can be controlled by applying an external voltage. Devices based on the discovery could find use in adaptive-focus systems that try to mimic how the human eye works. More The physics of exotic soap bubbles The Telegraph Share
Developments in the study of neutrons - a building block of all matter - may help us understand the Big Bang. Read the associated APS Physics Synopsis. More
US envoy blasts Iran's nuclear 'deceit' FOX News Share
U.S. Energy Secretary Steven Chu accused Iran of nuclear "denial, deceit and evasion," warning that Tehran's decision to move some uranium enrichment facilities to an underground bunker brings it closer to being able to producing the fissile core of a warhead. More Ringing the Sun Science News Share
An asteroid-sized black hole passing through the sun would ring it like a clapper striking a bell, according to new computer simulations. Read the associated APS Physics Synopsis. More
The strange physics - and singular sights - inside black holes Discover Magazine Share
Nothing that enters a black hole ever comes out. But one astrophysicist has stepped inside and created striking visualizations of passing the event horizon, carried on a waterfall moving faster than the speed of light. More My 2 Suns: Bounty of new exoplanet discoveries includes a world orbiting a binary star Scientific American Share
Leading planet hunters from around the world announced the discovery of some 75 extrasolar planets, and hints of many more. More
'Tug-of-war' prompts chemical reaction Physics World Share
Researchers have shown that mechanical force can bring about unique chemical reactions. Their experiment involved pulling on molecules in solution using ultrasound and suggests that mechanics could open up other new reaction pathways in chemistry. The discovery could also lead to the development of new technologies such as force-activated sensors or reversible adhesives. More
Neutron star smash-ups may forge gold NewScientist Share
Where did all the gold come from? Violent collisions between dense former stars may be why gold, lead, thorium and other heavy elements exist in such abundance. Only hydrogen, helium and lithium were present after the big bang. Ordinary stars then fused elements up to the mass of iron. Anything heavier was created when smaller atoms captured neutrons, some of which then decayed into protons. More |
