Study on sexual behavior discovers why some people ‘stay’ while others ‘stray’
Scientists said Wednesday they had amassed the first evidence to back theories that people fall into two broad categories — promiscuity or faithfulness — when it comes to sex.
Everyone knows of couples that are sexually faithful, but also of men cut out to be cads rather than dads.
What has been lacking are the statistics to show these differences, which is a key step to explaining them.
Now a team at the University of Oxford say they have found just that.
Finger length
The longer your ring finger is, compared to your index finger, the higher the likely concentrations of foetal testosterone.
This in turn has been linked to a higher statistical likelihood of promiscuity.

How To Find A Stolen Bicycle: Smart Pedals
Bikes are stolen all the time. This impedes people’s ability to get to jobs in a timely way, and also costs them a bit of money and inconvenience. Sometimes with no car, no decent mass transit, and no bicycle, these people are really left out of luck, perhaps losing a job.
Even with expensive locks, we must realize that our bikes can one day be stolen. A new technology to can help a great deal if such a thing happens — smart pedals.
The smart pedal from French startup Connected Cycle also includes technology that will notify a bicycle owner if their bike is moved. A tracking app installed on a smartphone reveals the bicycle’s new location.
Along with this personal sleuthing techno system, other conveniences from the pedals and app aid the bicyclist. They can track the speed of cyclists, track routes as other apps do, track inclines and declines, and for the obsessive, the cyclist’s calories burned. Additionally, the smart pedals generate electricity and include their own internet connection.

Helium Balloon Flight Breaks 2 Longstanding Records
ALBUQUERQUE, N.M. (AP) — Two pilots in a helium-filled balloon landed safely off the coast of Mexico early Saturday after an audacious, nearly 7,000-mile-long trip across the Pacific Ocean that shattered two long-standing records for ballooning.
The pilots landed 4 miles offshore in Baja California about 300 miles north of the popular beach destination of Cabo San Lucas, greeted by a team of balloon enthusiasts who assisted with the landing. The pilots came in low and dropped thick trailing ropes into the ocean to help slow the balloon before setting down in a controlled water landing.
Troy Bradley of Albuquerque and Leonid Tiukhtyaev of Russia lifted off from Japan Sunday morning, and by Friday, they beat what's considered the "holy grail" of ballooning achievements, the 137-hour duration record set in 1978 by the Double Eagle crew of Ben Abruzzo, Maxie Anderson and Larry Newman in the first balloon flight across the Atlantic. They also easily exceeded the distance record of 5,209 miles set by the Double Eagle V team during the first trans-Pacific flight in 1981.

Rare goblin shark caught in Australian trawl net
‘Living fossil’ species dates back 125 million years and is typically found in depths of 3,000 to 4,000 feet; this juvenile was taken at 2,000 feet
The goblin shark is the world’s rarest shark, and a contender for the world’s ugliest sea creature. It is the lone surviving member of the Mitsukurinidae family, which dates back 125 million years.

Mysterious Blainville's Beaked Whale Makes An Appearance In Hawaii
Blainville's beaked whales can be as long as 20 feet and weigh as much as 2,300 pounds. They live in tropical waters worldwide, but often spend most of their time at deep depths, where they hunt for squid and small fish.
Because they swim so deep -- they've been known to dive seven times deeper than humpbacks -- Blainville's beaked whales are difficult to observe.
As a result, Blainville's beaked whales are somewhat of a mystery: Scientists don’t know how many there are, or what their life span is.
