The math behind these formulas may be elegant, but applying them is more complicated.

I am a theoretical neuroscientist. I study models of brain circuits, precisely the sort of models that would be needed to try to reconstruct or emulate a functioning brain from a detailed knowledge of its structure. I don’t in principle see any reason that what I’ve described could not someday, in the very far future, be achieved (though it’s an active field of philosophical debate). But to accomplish this, these future scientists would need to know details of staggering complexity about the brain’s structure, details quite likely far beyond what any method today could preserve in a dead brain.

The researchers culled tens of thousands of photos from an online-dating site, then used an off-the-shelf computer model to extract users’ facial characteristics—both transient ones, like eye makeup and hair color, and more fixed ones, like jaw shape. Then they fed the data into their own model, which classified users by their apparent sexuality. When shown two photos, one of a gay man and one of a straight man, Kosinski and Wang’s model could distinguish between them eighty-one per cent of the time; for women, its accuracy dropped slightly, to seventy-one per cent.

For most of the past century, drugs approved and released to market have been tested only on male patients, leading to improper dosing and unacceptable side effects for women. The important physiological differences between men and women have only recently been taken into consideration in medical research. Emergency doctor Alyson McGregor studies these differences, and in this fascinating talk she discusses the history behind how the male model became our framework for medical research and how understanding differences between men and women can lead to more effective treatments for both sexes

An exhibition at the British Library in London reveals the importance that visualising data has had on the scientific process – from 19th Century ship logs that still influence climate science, to models used to forecast the 2009 influenza pandemic.These images not only aid scientific progress, but also help to change the world.

I believe a major change in our perspective on consciousness may be necessary, a shift from a credulous and egocentric viewpoint to a skeptical and slightly disconcerting one: namely, that we don’t actually have inner feelings in the way most of us think we do.

How does the brain go beyond processing information to become subjectively aware of information? The answer is: It doesn’t. The brain has arrived at a conclusion that is not correct. When we introspect and seem to find that ghostly thing — awareness, consciousness, the way green looks or pain feels — our cognitive machinery is accessing internal models and those models are providing information that is wrong. The machinery is computing an elaborate story about a magical-seeming property. And there is no way for the brain to determine through introspection that the story is wrong, because introspection always accesses the same incorrect information.

A team of scientists unveiled a new tree of life on Monday, a diagram outlining the evolution of all living things. The researchers found that bacteria make up most of life’s branches.

Female impersonators, midgets, hermaphrodites, tattooed (all over) men, an albino sword swallower, a human pincushion, a Jewish giant: “Characters in a Fairy Tale for Grown Ups” is the way Diane Arbus once described her subjects—“people who appear like metaphors somewhere further out than we do,” she also said, “invented by belief.”

Find out how and why the Earth's climate is changing

What Dr. Brown and a fellow Caltech professor, Konstantin Batygin, have not done is actually find that planet

“It is clear to us that Russia will protest,” Kaminski said. “The Kremlin’s diplomats react very violently every time a Soviet monument is removed.”He adds that the issue needs to be resolved quickly, so as not to allow time for “provocation” from Russia.The INR’s initiatives have often divided Russian and Polish opinion, most recently with the launch of a board game modeled on Monopoly that shows the difficulties of the Communist-era economy. The INR-designed game has been a bestseller in Poland and elsewhere. But Russia banned the game earlier this month after it failed to convince the creators to remove all historical references to Communism and turn it into a board game about shopping.

And with the Islamic State’s prolific use of social media, terrorism experts and government agencies continually search for clues in posts and Twitter messages that appear to promote the militants’ cause.A physicist may not seem like an obvious person to study such activity. But for months, Neil Johnson, a physicist at the University of Miami, led a team that created a mathematical model to sift order from the chaotic pro-terrorism online universe.
