Men's Sweat Attracts Women
According to a new study to pick up the ladies, a 20-minute workout on the elliptical machine should do just fine.
The study, published in The Journal of Neuroscience and conducted by researchers at the University of California at Berkeley, found that women who sniffed a chemical found in male sweat experienced "heightened mood, physiological arousal and subjective sexual arousal."
"This is the first time anyone has demonstrated that a change in women hormonal levels is induced by sniffing an identified compound of male sweat," said Claire Wyart, a post-doctoral fellow at UC Berkeley and the leader of the study.
The study focused on androstadienone (AND), a component of sweat. Previous studies have found male sweat -- specifically from the underarm -- can increase the secretion of luteinizing hormone in women, responsible for stimulating ovulation.
Another study showed female sweat, when applied to the upper lip of another woman, can alter the menstrual cycle of the subject to coincide with the sweat provider, according to a press release.
"Many people argue that human pheromones don't exist, because humans don't exhibit stereotyped behavior," Wyart said. "Nonetheless, this male chemical signal, [AND], does cause hormonal as well as physiological and psychological changes in women. More cognitive studies need to be done to understand how [AND] affects female cognitive functions."
Research was conducted on 48 Berkeley undergraduate women, each of which took 20 sniffs from vials containing either AND or a control -- in this case -- yeast. Scientists then took saliva samples from the women to measure cortisol levels, a hormone used to respond to stress. The increased hormone levels were found within 15 minutes after the testing began and lasted for more than an hour.
World's Biggest Train Set - Miniatur Wunderland
This is the world's biggest train set which covers 1,150 square meters (12,380 square feet), features almost
six miles of track and is still not complete.
six miles of track and is still not complete.
Twin brothers Frederick and Gerrit Braun, 41, began work on the 'Miniatur Wunderland' in 2000
The set covers six regions including America , Switzerland , Scandinavia , Germany and the Austrian Alp.
The American section features giant models of the Rocky Mountains, Everglades, Grand Canyon ..
...and Mount Rushmore
The Swiss section has a mini-Matterhorn
The Scandinavian part has a 4ft long passenger ship floating in a 'fjord'
It is expected to be finished in 2014, when the train set will cover more than 1,800 square meters (19, 376 sq ft)
and feature almost 13 miles of track, by which time detailed models of parts of France, Italy and the UK will have been added.
and feature almost 13 miles of track, by which time detailed models of parts of France, Italy and the UK will have been added.
It comprises 700 trains with more than 10,000 carriages and wagons.
The longest train is 46ft long
The scenery includes 900 signals, 2,800 buildings, 4,000 cars - many with illuminated headlights..
...and 160,000 individually designed figures
Thousands of kilograms of steel and wood was used to construct the scenery...
The 250,000 lights are rigged up to a system which mimics night and day by automatically turning them on and off
The whole system is controlled from a massive high-tech nerve centre
Gerrit said: "Our idea was to build a world that men, woman, and children can be equally astonished and amazed in"
Frederik added: "Whether gambling in Las Vegas , hiking in the Alps or paddling in Norwegian fjords - in Wunderland everything is possible"
