Two things men believe; first, women like them more when they are taken and second, a woman's relationship status influences her interest in the opposite sex. 

At least that second part appears to be true.   

In a new study, women both with and without sexual partners showed little difference in their subjective ratings of photos of men when considering such measures as masculinity and attractiveness.   However, the women who did not have sexual partners spent more time evaluating photos of men, demonstrating a greater interest in the photos. No such difference was found between men who had sexual partners and those who did not.

NASA's Chandra X-ray Observatory has found a cosmic "ghost" lurking around a distant supermassive black hole. This is the first detection of such a high-energy apparition, and scientists think it is evidence of a huge eruption produced by the black hole.

This discovery presents astronomers with a valuable opportunity to observe phenomena that occurred when the Universe was very young. The X-ray ghost, so-called because a diffuse X-ray source has remained after other radiation from the outburst has died away, is in the Chandra Deep Field-North, one of the deepest X-ray images ever taken. The source, a.k.a. HDF 130, is over 10 billion light years away and existed at a time 3 billion years after the Big Bang, when galaxies and black holes were forming at a high rate.

A new study carried out at the University of Leicester reveals that an alternative to oil could be found in ancient sea deposits dating to 300 million years ago.

Shale gas sourced in mudstones in shallow water seaways could provide the future alternative to fuel modern society in the wake of demands to find new energy sources, according to the doctoral research.

These mudstones, now exposed across central and northern England, contain up to 14% carbon.

A study in Nature has helped define the potentially significant contribution of permafrost thaw to atmospheric concentrations of carbon, which have already reached unprecedented levels.

A large amount of organic carbon in the tundra is stored in the soil and permafrost. This pool of carbon, deposited over thousands of years, remains locked in the perennially frozen ground. In recent years this area began to thaw, providing increased access to plants and microbes that could shift the carbon from the land to the atmosphere.

You aren't really somebody unless you have an aircraft carrier named after you and 40th US president Ronald Reagan has just that.   Now he will have a Miss California on board too; in this case, Carrie Prejean, who's arguably the most famous beauty queen who didn't actually win, thanks to openly gay judge Perez Hilton making no secret of the fact that her personal opinions on gay marriage had no place in any contest he took part in unless they agreed with his, thus making her a darling of both Christians and conservatives in the process.

As many as 700,000 people in the UK suffer from a heart abnormality called arrhythmia, a potentially fatal condition, which the majority of Londoners have never heard of - according to a recent survey conducted by YouGov[1]. Many of the deaths associated with arrhythmias could be prevented due to advances in the identification and treatment of high risk patients.
