Still faster than light
The Economist    Share    Share on FacebookTwitterShare on LinkedinE-mail article
A simplified test backs up an earlier experiment that found neutrinos traveling faster than light. In addition, other physicists are proposing that signs of faster-than-light neutrinos, if they exist, should be apparent in experiments at the Large Hadron Collider. Read the abstract of the forthcoming Physical Review D article. More

Is the new physics here? Atom smashers get an antimatter surprise
Yahoo News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The world's largest atom smasher, designed as a portal to a new view of physics, has produced its first peek at the unexpected: bits of matter that don't mirror the behavior of their antimatter counterparts. The discovery, if confirmed, could rewrite the known laws of particle physics and help explain why our universe is made mostly of matter and not antimatter. More

Leonardo's formula explains why trees don't splinter
Wired Science    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The graceful taper of a tree trunk into branches, boughs, and twigs is so familiar that few people notice what Leonardo da Vinci observed: A tree almost always grows so that the total thickness of the branches at a particular height is equal to the thickness of the trunk. Until now, no one has been able to explain why trees obey this rule. But a new study may have the answer. Read abstract to the forthcoming Physical Review Letters article. More

Microscope probes living cells at the nanoscale
Physics World    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Researchers say they have invented a new microscopy technique for imaging live tissue with unprecedented speed and resolution. The technique involves using the tiny tip of an atomic force microscope to tap on a living cell and analysing the resulting vibrations to reveal the mechanical properties of cell tissue. The team says that the technique could have widespread applications in medicine. However, another expert in the field suggests that the group has not demonstrated the superiority of the technique to those already available. More

Tall water waves behave unexpectedly
PhysOrg    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Investigations of the behavior of large-amplitude standing water waves show that the waves' behavior cannot be explained as simply as previously proposed. Read the associated Physical Review Letters abstract. More

Not pulling your leg: Tractor beams may be possible
ScienceNOW    Share    Share on FacebookTwitterShare on LinkedinE-mail article
It's not nearly powerful enough to pull in the Millennium Falcon, but four groups of physicists have independently come up with the same basic idea for a real-life tractor beam. The laser beam the groups have dreamed up could drag an object the size of only a grain of salt or smaller, but experts say it could provide a new tool for manipulating tiny objects such as cells. Read the abstract to the forthcoming Physical Review Letters paper. More

How to turn darkness into light
Physics World    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Quantum mechanics tells us that the vacuum is not empty but is filled with virtual particles that pop into and out of existence. Normally these particles are hidden from our view, but now a team of physicists has used the electrical equivalent of an ultrafast mirror to convert virtual photons into real electromagnetic radiation. Known as the dynamical Casimir effect, it was first predicted more than 40 years ago. More

Cuts loom for science as 'supercommittee' fails
New Scientist    Share    Share on FacebookTwitterShare on LinkedinE-mail article
After three months of wrangling, the congressional "supercommittee" charged with lopping $1.5 trillion from the U.S. federal budget deficit over the next 10 years conceded that it has failed to agree on a plan. According to the rules laid down when the committee was established in early August, cuts totalling $1.2 trillion over a decade should now be triggered automatically across the federal budget from 2013 onwards.

Plastic isn't over yet
Science News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
A tough new plastic that's easily healed if scratched or damaged could find use in products prone to getting beat up, such as paints or parts for cars and sailboats. What's more, it can be ground up and recycled into completely new products like plastic molding for electronic devices or optical lenses. More
