The theory has long been touted as the best hope for a unified “theory of everything,” bringing together the physics of the vanishingly small and the mindbendingly large. But it has also been criticized and even ridiculed for failing to make any predictions that could be checked experimentally. It’s not just that we don’t have big enough particle accelerators or powerful enough computers; string theory’s most vocal critics charge that no experiment could even be imagined that would prove it right or wrong, making the whole theory effectively useless.
Now, physicists at Imperial College London and Stanford University have found a way to make string theory useful, not for a theory of everything, but for quantum entanglement.
“We can use string theory to solve problems in a different area of physics,” said theoretical physicist Michael Duff of Imperial College London. “In that context it’s actually useful: We can make statements which you could in principle check by experiment.” Duff and his colleagues describe their findings in a paper in Physical Review Letters September 2.
String theory suggests that matter can be broken down beyond electrons and quarks into tiny loops of vibrating strings. Those strings move and vibrate at different frequencies, giving particles distinctive properties like mass and charge. This strange idea could unite all the fundamental forces, explain the origins of fundamental particles and connect Einstein’s general relativity to quantum mechanics. But to do so, the theory requires six extra dimensions of space and time curled up inside the four that we’re used to.

Spiders may trap unsuspecting prey by sucking them in using electrostatic attraction, new research suggests.
The new study, published Thursday in the journal Scientific Reports, found that the spiderweb of the common cross spider (or garden spider) is attracted to electrically charged objects, with the sticky threads of spider silk arcing toward each other in response to a charged object.
Stroke of inspiration
Some flying insects, as they flap their wings, for instance, generate an electric charge. As such the new results suggest that charged bugs such as honeybees could be sucked into, and then trapped by, a spider’s sticky web as they fly by.
“Charged insects can produce a deformation of a spiderweb,” said study co-author Victor Ortega-Jimenez, a biologist at the University of California, Berkeley. “Any insect that is flying very close to the spiderweb can be trapped by the electrostatic effect.”

Legendary beast, or harmless geological activity? That is the question raised after a scientist’s surprising theory about the Loch Ness Monster resurfaced recently.
Italian geologist Luigi Piccardi first floated his theory in 2001, telling a meeting of colleagues organized by the Geological Society of London and the Geological Society of America that seismic activity may underlie the majority of supposed monster sightings around the Scottish lake from which the fabled creature takes its name.
The first claimed sighting of “Nessie” occurred in the sixth century, according to Scientific American. Legend has it that the creature appears along with earth tremors and bubbling from the bottom of Loch Ness, one of Britain’s largest freshwater lakes.
Formed as a result of a long-ago collision between the northern tip of Scotland and the rest of Britain, the loch sits over the 62-mile Great Glen fault line. Piccardi argues that this position may have fueled centuries of Loch Ness Monster rumors.

An 1,800-year-old stone carving of what may be the head of a Roman god was recently found in an ancient garbage dump, British archaeologists announced today (July 3).
An undergraduate student at Durham University discovered the largely intact head during an archaeological dig at the Binchester Roman Fort, a major Roman Empire fort built around A.D. 100 in northeastern England’s County Durham.
Archaeologists involved in the dig believe that somebody probably tossed the 8-inch-long (20 centimeters) statue in the garbage when the building was abandoned in the fourth century, during the fall of the Roman Empire.
The team is still not certain who the carved head is meant to represent, though they have noted its resemblance to a similar stone head discovered in 1862 inscribed with the name “Antenociticus” — a Celtic deity associated with military prayers in that particular region.

A new fossilized, cigar-shaped creature that lived about 520 million years ago has been unearthed in Morocco.
The newfound species, Helicocystis moroccoensis, has “characteristics that place it as the most primitive echinoderm that has fivefold symmetry,” said study co-author Andrew Smith, a paleontologist at the Natural History Museum in London, referring to the group of animals that includes starfish and sea urchins. Modern echinoderms typically have five-point symmetry, such as the five arms of the starfish or the sand dollar’s distinctive pattern.
The primitive sea creature, described today (June 25) in the journal Proceedings of the Royal Society B, could even change its body shape from slender to stumpy. Researchers say it is a transitional animal that could help explain how early echinoderms evolved their unique body plans, Smith said.
.
During the Cambrian explosion, the diversity of life exploded and bizarre sea creatures such as the Helcocystis moroccoensis flourished.

The habitable zone of a nearby star is filled to the brim with planets that could support alien life, scientists announced today (June 25).
An international team of scientists found a record-breaking three potentially habitable planets around the star Gliese 667C, a star 22 light-years from Earth that is orbited by at least six planets, and possibly as many as seven, researchers said. The three planet contenders for alien life are in the star’s “habitable zone” — the temperature region around the star where liquid water could exist. Gliese 667C is part of a three-star system, so the planets could see three suns in their daytime skies.
The three potentially rocky planets in Gliese 667C’s habitable zone are known as super-Earths — exoplanets that are less massive than Neptune but more massive than Earth. Their orbits make them possible candidates for hosting life, officials from the European Southern Observatory said in a statement.

Farmers expect to reap what they sow. So it was quite a surprise when Bruce Lilienthal found a meteorite half-buried in a field on his farm in Minnesota’s Sibley County, the Minneapolis Star Tribune reported.
“We didn’t know what it was at first,” Lilienthal said of the flat, oddly heavy rock in an interview with KEYC-TV.
“We’ve done enough tests to be sure it’s a meteorite,” Dr. Calvin Alexander, a meteorite expert and professor of earth sciences at the University of Minnesota, told the Star Tribune. “It is not part of the Earth. It fell out of the sky.”
Dr. Alexander told The Huffington Post in an email that he examined the 33-pound rock at his office in Minneapolis on May 30, after Lilienthal and his wife brought it in. A variety of tests — including chemical analysis and electron microscopy — convinced him that what he calls the “Lilienthal object” is an iron meteorite.

In the film “Eternal Sunshine of the Spotless Mind,” the characters undergo a scientific procedure to erase their memory. But what if instead of erasing memory, you could restore it? One neuroscientist aims to do just that.
Theodore Berger of the University of Southern California is developing a prosthesis to restore memory, by replacing a circuit in the brain’s hippocampus. Berger described the device at the Global Future 2045 International Congress, held here June 15-16. Already successful in rats and monkeys, the prosthesis is now being tested in humans.
Memory machine
The hippocampus, a brain structure tucked deep in the brain’s temporal lobe, converts short-term memories to long-term ones. Epilepsy or other neurological disorders can damage the hippocampus, preventing a person from retaining new memories.
.
A prosthetic device could restore memory to patients with brain damage due to epilepsy or other conditions. It’s being developed by USC’s Dr. Theodore Berger (above).
