For more than two decades, nonscientists and engineers have made molecular-scale motor, switches, propellers, ratchets, and even the "nanocar" above that rolls when its metal "road" is heated. But what can we actually do with these things? The journal Nature looks at today's efforts to develop useful applications for molecular machines, from drug delivery systems inside the body to a new kind of high-density molecular memory for computers.

In Beijing, China banned 2.5 million cars from driving for 2 weeks to get this beautiful blue sky for a World War II commemorative parade. As soon as the parade was over, the ban was lifted, and the blue vanished within 24 hours. Read the rest
New research suggests that traffic noise (apart from pollution and general hectic motion) degrades the natural habitat of songbirds, and perhaps other animals. Boise State University biologists created a "phantom road" using speakers to create traffic noise in a natural, roadless songbird habitat. Read the rest
In the book The Man Who Wasn't There, Anil Ananthaswamy explores mysteries of self, including the weirdness of autoscopic phenomena, a kind of hallucination in which you are convinced that you are having an out-of-body experience or face to face with your non-existent twin. Read the rest

A few months back, Marianne Winkler found a bottle on a German beach with a message inside requesting its return to the Marine Biological Association (MBA) that had dropped more than 1,000 bottles into the North Sea as part of a study of currents. Thing is, that experiment took place more than a century ago. From National Geographic:
"We haven't had [a bottle] returned in living memory," says Guy Baker, an MBA spokesperson.
(Former MBA president and lead researcher on the bottle study George Parker) Bidder got about half of his messages back, says Baker. And the longest it took for one of his bottles to come home—before this current one—was about four years....
Bidder's bottle has also been submitted to the Guinness World Records for consideration as the oldest message in a bottle ever recovered. The current record-holder is a 99-year-old bottle discovered in a fishing net off the Shetland Islands in 2013.

Two recent University of Miami research studies suggest that politicians with deep voices are more likely to win an election than candidates with higher-pitched voices. "With one exception: when running against a female opponent, candidates with higher voices were more popular, especially if they were men," according to Scientific American. Read the rest
When you see someone yawn and then feel the urge to yawn yourself, it's a sign of social traits like empathy. According to new research from Baylor University, people who scored higher on the Psychopathic Personality Inventory test were less likely to "catch" a yawn. From Baylor University:
Based on the psychological test results, the frequency of yawns and the amount of physiological response of muscle, nerve and skin, the study showed that the less empathy a person had, the less likely he or she was to "catch" a yawn.
"The take-home lesson is not that if you yawn and someone else doesn't, the other person is a psychopath," (lead researcher Brian) Rundle cautions. "A lot of people didn't yawn, and we know that we're not very likely to yawn in response to a stranger we don't have empathetic connections with.
"But what we found tells us there is a neurological connection -- some overlap -- between psychopathy and contagious yawning. This is a good starting point to ask more questions."
And if you'd like to learn more about what makes a psychopath, I highly recommend Jon Ronson's excellent book "The Psychopath Test: A Journey Through the Madness Industry."
