Are some sex positions better than others? You may have heard that some positions, such as your partner on top (missionary position), are better than others for conception. In fact, there's no evidence to back these theories up. Experts just haven't done the research yet. What experts have done, though, is use scanning to reveal what's going on inside when you're doing the deed. Some brave couples volunteered to be scanned using magnetic resonance imaging (MRI) while having sex.

A common tetanus booster shot given to patients with a deadly form of brain cancer shortly before an experimental cancer vaccine prolonged their survival, a small study found. Duke University researchers who led the study say the regimen could mark a new way to stimulate the body’s immune system to attack tumors, a growing area of interest in cancer treatment. The scientific journal Nature published the study results online Wednesday.

                                          The medical student researchers and their faculty team in Boston University of Hawaiʻi John A. Burns School of Medicine researchers had already sparked national news when they presented research posters last November in Boston at the national conference of the American Association for the Study of Liver Diseases, the leading organization of scientists and health-care professionals committed to preventing and curing liver disease. The findings by the JABSOM students and supervising faculty led to the issuance of several national health warnings and triggered an overdue discussion over whether strict regulations are warranted for health supplements.

Astronomers have found the most conclusive evidence yet that a large watery ocean lies beneath the surface of Jupiter's moon Ganymede. Scientists have suspected for decades that a subterranean ocean might slosh between the rocky mantle and icy crust of the largest moon in our solar system, but they had not been able to prove it definitively until now. Using the Hubble Telescope, a team of researchers has detected slight fluctuations in two bands of glowing aurorae in Ganymede's atmosphere that they say could occur only if the moon contained a salty body of water.

California Institute of Technology-   The Center for Financial Studies has awarded its Deutsche Bank Prize in Financial Economics to Stephen A. Ross (BS '65), a professor of finance at MIT and member of Caltech's Board of Trustees. The center cited Ross for his groundwork and fundamental contributions to the analytical development of financial economics. "The work of Stephen A. Ross has shaped today's thinking in financial innovation, practice, and policy," says Jan Pieter Krahnen, the center's director. "For more than 25 years, major models developed by him have marked the economic world. His models relate to the theory of asset pricing, the analysis of the term structure of interest rates, understanding option prices, and the basic structure of the principal-agent problem." "Steve has completed several of the most important pieces of research in this field," says Richard Roll, the Linde Institute Professor of Finance at Caltech...

Microscopic view of the frontal cortex of a mouse showing the two types of neurons (ChAT+, purple; ChAT-, green) that stem directly from the basal ganglia. Image: Arpiar Saunders and Chip Gerfen It’s been “known” for decades: Sensory, motor and cognitive signals come in from the brain’s cortex and are processed in the basal ganglia. The basal ganglia then send out signals that get routed through the thalamus and back to the cortex. Except not always, according to a new study in animal models. The basal ganglia can also talk back directly to the cortex, no thalamus required. The findings, published this week in Nature, upend classic anatomy and provide possible new insights into psychiatric diseases such as schizophrenia.

Danny Welbeck punished his former club with the decisive goal in Monday's FA Cup clash. MANCHESTER, England -- Goals from Nacho Monreal and Danny Welbeck were enough to stun Man United 2-1 in their FA Cup sixth round clash. Here are three quick observations from Old Trafford. 1. Welbeck returns to haunt Man United Manchester United are used to their homegrown talents delivering valuable winners. It has happened time and again in the days of Bobby Charlton and George Best, Ryan Giggs and David Beckham to name but four. This was something altogether different. This was a goal to make them regret, not rejoice. This was a case of Louis van Gaal being punished in spring for his summer mistakes. It is a source of pride at Manchester United that they have named a product of the club's youth system in the matchday squad for every game since 1937. One duly started in this occasion, only he was in the Arsenal ranks. Danny Welbeck, a Longsight lad, Mancunian and Unit...
