In many ways the Internet is the ultimate virtual laboratory. Social media and news sites tell the casual observer much about our priorities and interests, whether it’s the grave prognosis of the U.S.’s ongoing “fiscal cliff” political negotiations or elation over England’s royal pregnancy. Social scientists believe that, beyond such superficial revelations, the Internet can also be a tool for conducting expansive, yet inexpensive research experiments at unprecedented speed. Duncan Watts has been studying the Internet’s impact on social behavior, and vice versa, for more than a decade. In 2001 Watts and fellow Columbia University sociologists published the results of their Small World Project, an e-mail version of sociologist Stanley Milgram’s famous 1967 “six degrees of separation” experiment that used snail mail to test the theory that every person on the planet is separated from everyone else by a chain of about six people. In 2006 Watts worked with a team of researchers on Music Lab, an online experiment that illustrated the difficulty of predicting a song’s popularity among a diverse group of listeners.

Sir Richard Branson wants his tourist spaceship also to become a high-altitude science platform. The billionaire’s rocket plane will carry six fare-paying passengers just above the atmosphere to experience a few minutes of weightlessness. But the vehicle has been designed so that its seats can be removed easily and the space filled with science gear. Passenger flights should begin in 18 months or so; research sorties could start soon after. The US space agency (Nasa) has already chartered the rocket plane. “It’s likely we might do some science flights quite early in the programme,” explained Will Pomerantz from Virgin Galactic. “Nasa is certainly eager to get their flights conducted; the ones they have already purchased. “It may also give us some additional time to show off the reliability and the operations of the vehicle, which would give our tourism customers even more confidence. “I think that if they see a Nasa flight has gone up and gone well, that will make them feel better about their purchase,” he told BBC News.

Recent study by connectome researchers, published in the journal Science, revealed that the brain’s neurons are not the haphazard tangle that some had thought, but are arranged in a tidy grid that resembles a city street map.
And if you have ever wondered what makes you, you, thensome of the world’s top neuroscientists might say: “You are your connectome.”
The connectome refers to the exquisitely interconnected network of neurons (nerve cells) in your brain. Like the genome, the microbiome, and other exciting “ome” fields, the effort to map the connectome and decipher the electrical signals that zap through it to generate your thoughts, feelings, and behaviors has become possible through development of powerful new tools and technologies.

Read of the day:
We understand ourselves through metaphors. Many of the metaphors have been metaphors of artifacts of things that humans have constructed. We understand the function of the heart through the metaphor of the function of tools that we can create. We have understood the function of the brain through the metaphor of the information processing systems that we can build. In some sense, that is right and inevitably right. What it will mean to understand the brain will always be to have a better and better metaphor, by way of a better and better comparison system, a thing we can build that’s closer and closer in its capacities to the human mind.
Current cognitive neuroscience is struggling to understand something that is beyond any of our current metaphors, and certainly beyond our current understanding. It feels like we are before the right concept. It feels like the physicists, before they distinguished heat and temperature. It feels like the things that we’re saying to ourselves right now don’t work because they confuse central distinctions. I don’t think I am currently inventing a better way, although I would love to be. I’m certainly trying to push the empirical approaches, the data that we can collect to make it force us to something more correct.
The feeling of working with the wrong concept, which I think many of us have, knowing that our best theories are still deeply confused, if not merely superficially wrong, can be disheartening. But it is also the promise of huge future discoveries. It’s only if you’re before a huge future discovery that you have a chance of living through one.

The first person electrically stimulate the brain of a living human during surgery was the 19th-century British neurosurgeon Sir Victor Horsley. The operation was to treat a deformation called an encephalocele, where the bones of the skull do not close properly in the womb, causing the brain to protrude from the head. Horsely applied a weak electrical current to the surgically exposed brain tissue, making the patient’s eyes swivel to the side, which told the surgeon that the out-of-place area was the top of the midbrain – normally a deeply embedded neural structure essential for directing vision.
