Men with premature ejaculation who used a topical spray five minutes before intercourse were able to delay their orgasm six times longer than normal, according to a study in the April issue of BJU International.

Three hundred men with clinically diagnosed lifelong premature ejaculation (PE) from 31 centres in the UK, Czech Republic, Hungary and Poland, were randomised into two groups. Two hundred used the PSD502 spray, which contains 7.5mg of lidocaine and 2.5mg of prilocaine, and 100 used a placebo spray with no active ingredients.

Patients with schizophrenia are able to correctly see through an illusion known as the 'hollow mask' illusion, probably because their brain disconnects 'what the eyes see' from what 'the brain thinks it is seeing', according to a joint UK and German study published in the journal NeuroImage. The findings shed light on why cannabis users may also be less deceived by the illusion whilst on the drug.

It fits on a fingertip: Noblella pygmaea is a midget frog, the smallest ever found in the Andes and among the smallest amphibians in the world. Only its croaking was to be heard from the leaves on the mossier ground of the “elfin forests” in the highlands of Manu National Park, before German and Peruvian herpetologists discovered the tiny little thing in south-eastern Peru.  

The popular name of the new species is fitting: Noble’s Pygmy Frog has an average length of 

On the eve of the Passover holiday, researchers from the University of Haifa reveal an exceptional and exciting archaeological discovery that dates back to the time of the People of Israel's settlement in the country: For the first time, enclosed sites identified with the biblical sites termed in Hebrew "gilgal", which were used for assemblies, preparation for battle, and rituals, have been revealed in the Jordan valley.

Saturn's largest moon, Titan, may have a subterranean ocean of hydrocarbons and some topsy-turvy topography in which the summits of its mountains lie lower than its average surface elevation, according to new research. 

Titan is also more squashed in its overall shape—like a rubber ball pressed down by a foot—than researchers had expected, said Howard Zebker, a Stanford geophysicist and electrical engineer involved in the work. The new findings may help explain the presence of large lakes of hydrocarbons at both of Titan's poles, which have been puzzling researchers since being discovered in 2007. 

The latest data from NASA and the University of Colorado at Boulder's National Snow and Ice Data Center show the continuation of a decade-long trend of shrinking sea ice extent in the Arctic, including new evidence for thinning ice as well.

The researchers, who have been tracking Arctic sea ice cover with satellites since 1979, found that the winter of 2008-09 was the fifth lowest maximum ice extent on record. The six lowest maximum events in the satellite record have all occurred in the past six years, according to CU-Boulder researcher Walt Meier of NSIDC.
