Do you fall in love using your heart or your brain?   It depends.    For your brain, says a new analysis by Syracuse University Professor Stephanie Ortigue that won't discourage drug use, falling in love elicits the same euphoric feeling as using cocaine,  but it also affects intellectual areas of the brain.  That's a pretty big endorsement of the brain being number one in romance.
So if love is in the brain and not the heart, is there 'love at first sight' after all?   The science says yes, according to the researchers, who found falling in love only takes about a fifth of a second.
 

Can skin cancer be treated with light? Scientists from the University of California, Irvine say they can treat skin cancer with light - the ability to image cancerous lesions using LEDs might advance a technique for treating cancer called photodynamic therapy (PDT).

In PDT, photosensitizing chemicals that absorb light are injected into a tumor, which is then exposed to light. The chemicals generate oxygen radicals from the light energy, destroying the cancer cells. PDT is currently approved by the U.S. Food and Drug Administration (FDA) for the treatment of esophageal and lung cancer.

Think you're no good at Chess?   Not a strategic thinker?   You're better at it than you may think.

When we make any decisions related to how we think someone else will act,  we must use reason to infer the other's next moves to decide what we must do. This recursive reasoning ability in humans has been thought to be somewhat limited but new research says people can engage in much higher levels of recursive reasoning than was previously thought. 

If an isolated question asks you if you are more inclined to vote for one politician who lies about limiting his campaign financing or one who agrees to use only matching public funds in the interests of campaign finance reform and sticks to it, who would you pick?  Obviously if political campaigns were limited to that one topic, the honest politician would win - but quality leadership incorporates 'negative' personality traits too and President Barack Obama was able to spend double the money on advertising of his opponent because he used that strategy wisely.

A new study says it isn't just human memories that fade - aging impacts the ability of honey bees to find their way home as well.

Bees are typically impressive navigators, able to wend their way home through complex landscapes after visits to flowers far removed from their nests, even after three to four days of flight time. Mature bees have piloted their way to and from the hive for five to 11 days and old bees have had more than two weeks of flight time but the paper says that aging impairs the bees' ability to extinguish the memory of an unsuitable nest site even after the colony has settled in a new home. 

49 light years away from Earth in the constellation Lyra is a binary star that may cause a rethink on how gas giant planets were created.  

Everyone loves the El Farol Bar in Santa Fe, New Mexico (especially W. Brian Arthur, who wrote this puzzle in 1994).

That is, everyone loves the El Farol as long as it's not too crowded.

If it's less than 60% full, it's more fun to be at the bar; if it's more than 60% full, it's more fun to stay home. This puzzle has one more catch: everyone has to decide whether or not to
go at exactly the same time, without communication.

So what should you do—stay home or go to the bar?

You can probably see the Catch 22 here.

Spanning the Kill Van Kull tidal strait and first opened in 1931, the Bayonne Bridge was the longest in the world until 1978 and is currently the fourth longest steel arch bridge in the world.  Today it carries about 20,000 vehicles per day over its four lanes and it was dramatically blown up in the Steven Spielberg-directed 2005 movie "War of the Worlds", starring Tom Cruise and Dakota Fanning.

In 2002, inspired by the events of the 9/11 terrorist attacks at the World Trade Center, eight-year-old Veronica Granite from New Jersey began a petition drive to illuminate her hometown bridge with red, white and blue lights, having seen tricolor lighting atop the Empire State Building during a visit to Liberty State Park.

Think feminists are angry?   Many zealots in any movement come across as bitter to outsiders but Professor Germaine Greer is giving a talk at the Literary Leicester Festival at the University of Leicester and intends to discuss what enormous fun she has had being a fearless international feminist icon and an academic through four decades of change - witnessing the change from the vaguely "Mad Men" period of the '60s, through the bizarre unisex beliefs of the '70s to today, where women get more PhDs than men but still like to have doors opened for them.
