Metal detector can identify buried bombs
NewScientist    Share    Share on FacebookTwitterShare on LinkedinE-mail article
A souped-up metal detector could one day tell whether buried objects are unexploded bombs or just harmless junk. The world is riddled with unexploded bombs left behind following munitions tests and warfare. Governments want to dig them up so the land they are in can be used again.

1 year after Fukushima: Could it happen in the US?
Scientific American    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Last year, on March 11, a deadly earthquake and tsunami rocked Japan, killing more than 15,000 people. To make matters worse, the natural disaster triggered a major crisis at the Fukushima Daiichi nuclear power station. The subsequent meltdown and radioactive release is the only event in history other than Chernobyl to rate as a "major accident" on an international scale of nuclear severity. Read the associated March meeting abstract. More

Warp drive could be a doomsday weapon
COSMOS magazine    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The search for the holy grail of intergalactic travel has encountered a slight hitch, say Australian scientists. Recent research predicts that upon reaching its destination, the theoretical Alcubierre warp drive – a speculative idea proposed by Mexican theoretical physicist Miguel Alcubierre in 1994 by which a spacecraft could be accelerated to speeds greater than the speed of light - would unleash a high energy cocktail of particles and radiation, blasting anyone in its path "into oblivion." Read the abstract of the forthcoming Physical Review D article.

LED's efficiency exceeds 100 percent
PhysOrg    Share    Share on FacebookTwitterShare on LinkedinE-mail article
For the first time, researchers have demonstrated that an LED can emit more optical power than the electrical power it consumes. Although scientifically intriguing, the results won't immediately result in ultra-efficient commercial LEDs since the demonstration works only for LEDs with very low input power that produce very small amounts of light. Read the associated APS Physics Synopsis. More

Wiping data will cost you energy
Physics World    Share    Share on FacebookTwitterShare on LinkedinE-mail article
For the first time physicists have measured the tiny amount of heat released when an individual bit of data is erased. Although the value was first predicted more than 50 years ago, it is so small that measuring it has proved impossible – until now. The experiment, which involved trapping a tiny bead in a double well created by a laser and tracking its motion as it flipped between wells, places a lower limit on the energy dissipated by logic circuits, which could affect the design of future electronic devices.

Neutrino 'costume change' mystery solved?
Discovery News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Another piece of the neutrino puzzle has fallen into place, thanks to new results announced by the Daya Bay collaboration in China. The experiment has only been up and running for a couple of months, but the international collaboration's latest measurement might explain how neutrinos change "flavors" - akin to a costume change - as they move through space.

Graphene in new 'battery' breakthrough?
Physics World    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Researchers at Hong Kong Polytechnic University claim to have invented a new kind of graphene-based "battery" that runs solely on ambient heat. The device is said to capture the thermal energy of ions in a solution and convert it into electricity. The results are in the process of being peer reviewed, but if confirmed, such a device might find use in a range of applications, including powering artificial organs from body heat, generating renewable energy and powering electronics.

New breed of 'nuclear clocks' could be 100 times more accurate than today's atomic timekeepers
Popular Science    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Atomic clocks are the most accurate timekeepers in the world, but a "nuclear clock" would be even better. Researchers have now proposed a new kind of atomic timekeeper that wouldn't lose or gain 1/20th of a second in 14 billion years (that's roughly the age of the entire universe). More




Blasting the photoelectric effect out of the quantum realm with a very intense light source
Ars Technica    Share    Share on FacebookTwitterShare on LinkedinE-mail article
In 1905, Albert Einstein showed that the photoelectric effect - the ability of metals to produce an electric current when exposed to light - could be explained if light is quantum, traveling in discrete bundles of energy. His model, the photon theory, won him the Nobel Prize in 1921, but it left us with an enigma: why does the classical model of electric fields yield correct experimental results for some systems, but fail so dramatically for the photoelectric effect?
