Did Higgs yield the most authors in a science study?

Scientists who announced two months ago observations of the elusive Higgs boson, the so-called "God particle," have had their research published in the peer-reviewed Physics Letters B, along with an astounding list of thousands of authors.

More than 5,000 researchers around the world are said to have contributed to the landmark studies by the CMS and ATLAS teams working at the European Organization for Nuclear Research (CERN). They said on July 4 the new boson they had observed was consistent with the Higgs, believed to be responsible for imparting all elementary particles in the universe with mass.

Two articles by the teams are each about 30 pages long. The combined author list takes up 19 pages of single-spaced text and appears to have roughly 6,000 names. Wouldn't that be fun to cite as a footnote in full? … Read more

Scientists teleport info 90 miles across islands

If only we were quantum states, we'd be playing Kirk and Scotty, popping around the universe until the inevitable failure in the transporter circuits.

European and Canadian scientists are pushing the envelope on quantum teleportation after having succeeded in beaming quantum states across some 90 miles in the Canary Islands.

The laser-locked telescopes on the islands of La Palma and Tenerife served as transporter rooms, teleporting information about the state of a pair of "entangled" particles.

The entanglement links the particles such that a change in one is registered in the other despite great distances between them. … Read more

Higgs boson revelation set for July 4: Fireworks, or dud?

Fireworks. Hot dogs. Beach blankets. Particle physics.

July 4 this year won't be just about Americans celebrating Independence Day and unofficially kicking off the the summer vacation season. It could also bring news of some significance from physicists in Europe who've been in hot pursuit of a mysterious subatomic particle known as the Higgs boson -- and a better glimpse at the nature of the universe.

The big-brain folks at CERN on Wednesday will be holding a seminar at which they plan to provide an update on the Higgs search, divulging the preliminary results of their 2012 data … Read more

CERN confirms speedy neutrinos follow laws of physics after all

Neutrinos can't travel faster than the speed of light after all.

CERN has confirmed that an initial reading, which recorded neutrinos -- nearly mass-less subatomic particles -- sent from CERN to the Gran Sasso laboratory as moving faster than light, was based off of a "faulty element" with the experiment's fiber-optic timing system.

The results, presented today at the International Conference on Neutrino Physics and Astrophysics in Kyoto, Japan, closes the chapter on a highly surprising finding last year that challenged the conventional wisdom of physics. The results quickly faced public scrutiny.

"Although this result … Read more

Neuroscientists develop video game for stroke recovery

After a stroke, it is often possible -- with months of therapy and determination -- for the brain to relearn how to control a weakened limb. Finding the resources (therapist, finances, time) can be the bigger hurdle.

Enter Circus Challenge, the first in a coming suite of action video games designed by Newcastle University stroke experts and the new company Limbs Alive to provide extra in-home therapy.

"Eighty percent of patients do not regain full recovery of arm and hand function and this really limits their independence and ability to return to work," pediatric neuroscience professor Janet Eyre … Read more

RunCore intros hard drive with a kill switch -- a real one

RunCore introduced a new SSD this week -- aptly named InVincible -- that offers one unique feature: a self-destruct button.

Well, the special hard drive actually includes two buttons; a green clicker for intelligent destruction (software-based wiping), and a red option that literally burns and cracks the storage chips within the drive via a major surge of electricity. … Read more

A rare look at a star's demise in a supermassive black hole

Once in awhile, a supermassive black hole gets a sumptuous treat. A passing star wanders too close and gets caught in the black hole's gravitational pull, like a fly trapped in a spider's web. The star then becomes an easy meal for the black hole, which tears its prey to bits and ingests a good portion of it.

Astronomers have witnessed several such disruptions before in distant galaxies, but usually only toward the end of the process. (These feedings are far too rare, however, to have been witnessed in our own Milky Way anytime in recent human history; … Read more

Secure the bath tub!

Shark Dash is another in a long line of Angry Birds clones, but offers enough variation in gameplay that it will appeal to any physics puzzle addict.

Like many sling-shot games, the goal with Shark Dash is to pull back, then fling your hero (in this case, a cute shark) to collect or destroy items in as few shots as possible. Also like Angry Birds, the storyline is simple: the evil rubber duckies have stolen Sharkee's girlfriend, Sally, and now Sharkee is exacting revenge while taking out the rubber duckies that continue to taunt him. Sound familiar? It's … Read more

Kick the iTunes habit and celebrate Record Store Day

Kick the iTunes habit and stop streaming, it's time to get physical with music you can touch!

Record Store Day is a celebration of the joys of buying music in the real world, and brick and mortar stores all over the country are participating in the event on Saturday, April 21.

The first Record Store Day was in 2007, and every year more and more stores get involved. The Record Store Day Web site has this quote from author Nick Hornby:

"Yes, yes, I know. It's easier to download music, and probably cheaper. But what's playing … Read more
