The G-spot is a figment of the imagination, say British researchers. A team at King’s College London based its conclusion on questionnaires sent to more than 1,800 women, all of them pairs of twins. If the G-spot existed as a physical entity, the results would have backed it up, they say.

“This is by far the biggest study ever carried out and it shows fairly conclusively that the idea of a G-spot is subjective,” said one of the lead researchers.

“I think this study proves the difference between popular science and biological or anatomical science,” a gynecologist tells the London Times. But it won’t end the debate, of course. “The biggest problem with their findings is that twins don’t generally have the same sexual partner,” says Rutgers professor Beverly Whipple, a believer who has written several books on the subject.

A piece of space debris moving toward the International Space Station may force astronauts to take shelter in an escape pod, according to NASA TV.

If NASA officials determine the space junk poses a serious threat, the two-man crew — which is not aware of the threat — will be alerted at about 10 a.m today. The astronauts may then be told to take shelter in the Soyuz escape pod.

NASA officials said the possible projected time of impact would be at about 1:19 p.m.

Mission control in Houston said it’s too late to move the space station out of the path of the debris, which is from a Russian satellite that collided with a U.S. satellite on Feb 10. The size of the piece of debris is not known.

The crew said goodbye to three other astronauts who undocked from the station Monday night and returned to Earth in Kazakhstan early Tuesday morning.

Claude Levi-Strauss, widely considered the father of modern anthropology for work that included theories about commonalities between tribal and industrial societies, has died. He was 100.

The French intellectual was regarded as having reshaped the field of anthropology, introducing structuralism _ concepts about common patterns of behavior and thought, especially myths, in a wide range of human societies. Defined as the search for the underlying patterns of thought in all forms of human activity, structuralism compared the formal relationships among elements in any given system.

During his six-decade career, Levi-Strauss authored literary and anthropological classics including “Tristes Tropiques” (1955), “The Savage Mind” (1963) and “The Raw and the Cooked” (1964).

Jean-Mathieu Pasqualini, chief of staff at the Academie Francaise, said an homage to Levi-Strauss was planned for Thursday, with members of the society _ of which Levi-Strauss was a member _ standing during a speech to honor his memory.

France reacted emotionally to his death, with French President Nicolas Sarkozy joining government officials, politicians and ordinary citizens populating blogs with heartfelt tributes.

Foreign Minister Bernard Kouchner praised his emphasis on a dialogue between cultures and said that France had lost a “visionary.” Sarkozy honored the “indefatigable humanist.”

Born on Nov. 28, 1908, in Brussels, Belgium, Levi-Strauss was the son of French parents of Jewish origin. He studied in Paris and went on to teach in Sao Paulo, Brazil, and conduct much of the research that led to his breakthrough books in the South American giant.

Levi-Strauss left France during as a result of the anti-Jewish laws of the collaborationist Vichy regime and during World War II joined the Free French Forces.

Levi-Strauss also won worldwide acclaim and was awarded honorary doctorates at universities, including Harvard, Yale and Oxford, as well as universities in Sweden, Mexico and Canada.

Although he reached the intellectual pantheon, Levi-Strauss remained down to earth.

A skilled handyman who believed in the virtues of manual labor and outdoor life, he was also an ardent music-lover who once said he would have liked to have been a composer had he not become an ethnologist.

He is survived by his sons Roman and Laurent.

A smaller, more agile cousin of the Tyrannosaurus rex has been identified. The skull and a nearly complete skeleton of Alioramus altai was discovered in Mongolia in 2001, and has features that distinguish it from its more lumbering cousin.

Unlike its “big bad boy” relatives, a study author tells National Geographic, “this one is more like a ballerina.” Alioramus is also much smaller, and has four horns not found on the T. Rex.

The horns, located on the dinosaurs cheeks, are too small for combat and “have never been seen in any carnivorous dinosaur before,” the author continues. Researchers surmise they could have been used to attract females. The lighter bones, which support a skull fitted with much weaker jaws than relatives, mean that the new species “probably relied more on speed, agility, and finesse, to go after smaller prey.” Click the link to see illustrations of the Alioramus altai.

A primate fossil found in Africa in 1994 predates the famous “Lucy””skeleton by 1 million years and offers clues to human evolution, researchers say.

“This is huge,” a paleoanthropologist tells the Washington Post. “This is the biggest discovery really since” Lucy. The researchers believe “Ardi”—Ardipithecus ramidus—lived in trees but could walk upright to forage for food on the ground.

“Ardi” would have been able to live in both the forest and savannah environments of Africa some 4 million years ago. “Is she our ancestor?” the team’s leader wonders. “Probably not. If she didn’t have any kids, tough luck, she’s nobody’s ancestor.” But the fossil is as close as scientists have come to the “last common ancestor” of chimps and humans, and suggests our primate cousins have evolved much more than we have.
