"When a surgeon cut into Henry Molaison's skull to treat him for epilepsy, he inadvertently created the most important brain-research subject of our time - a man who could no longer remember, who taught us everything we know about memory. Six decades later, another daring researcher is cutting into Henry's brain. Another revolution in brain science is about to begin."

"IT IS A SPECTATOR SPORT to look at someone else's books, if not an act of voyeurism or armchair psychology," wrote Henry Petroski in " The Book on the Bookshelf." Yet when the books don't belong to an individual, but rather to a hotel or a bar, it is not armchair psychology - it is an invitation to a chance encounter.

A new speed-reading app, Spritz, premiered in March 2014. Its makers claim that Spritz allows users to read at staggeringly high rates of speed: 600 or even 1,000 words per minute. (The average college graduate reads at a rate of about 300 words per minute.) Spritz can do this, they say, by circumventing the limitations imposed by our visual system. The author of this article argues that your brain has an even more superior "app": expertise, which creates a happy balance between speed and comprehension. In their forthcoming book, Make It Stick: The Science of Successful Learning, researchers Henry Roediger III and Mark McDaniel (along with writer Peter Brown) liken expertise to a "brain app" that makes reading and other kinds of intellectual activity proceed more efficiently and effectively. In the minds of experts, the authors explain, "a complex set of interrelated ideas" has "fused into a meaningful whole." The mental "chunking" that an expert - someone deeply familiar with the subject she's reading about - can do gives her a decided speed and comprehension advantage over someone who is new to the material, for whom every fact and idea encountered in the text is a separate piece of information yet to be absorbed and connected. People reading within their domain of expertise have lots of related vocabulary and background knowledge, both of which allow them to steam along at full speed while novices stop, start, and re-read, struggling with unfamiliar words and concepts. Deep knowledge of what we're reading about propels the reading process in other ways as well. As we read, we're constantly building and updating a mental model of what's going on in the text, elaborating what we've read already and anticipating what will come next. A reader who is an expert in the subject he's reading about will make more detailed and accurate predictions of what upcoming sentences and paragraphs will contain, allowing him to read quickly while filling in his alrea

Fun video. "Finding your name in the dictionary as a noun is a sure-fire litmus test for having made a impact on culture and history. Just look at OED-approved fine folks like Charles Boycott, Samuel Maverick, Joseph-Ignace Guillotine, Henry Shrapnel, and Lord Cardigan. But there are unsuspected downsides to being reduced to a noun - just ask suffragette and women's rights pioneer Amelia Bloomer, now equated with a baggy pair of women's underpants."

The problem of looking at our devices nonstop is physiological and social. The average human head weighs between 10 and 12 pounds, and when we bend our neck to use digital devices, the gravitational pull on our head and the stress on our neck increases to as much as 60 pounds of pressure. That common position leads to incremental loss of the curve of the cervical spine. Posture has been proven to affect mood, behavior and memory, and frequent slouching can make us depressed, according to the National Center for Biotechnology Information. The way we stand affects everything from the amount of energy we have to bone and muscle development, and even the amount of oxygen our lungs can take in. A study in 2010 found that adolescents ages 8 to 18 spent more than 7.5 hours a day consuming media. In 2015, the Pew Research Center reported that 24 percent of teenagers are "almost constantly" online. Adults aren't any better: Most adults spend 10 hours a day or more consuming electronic media, according to a Nielsen's Total Audience Report from last year. "Mobile devices are the mother of inattentional blindness," said Henry Alford, the author of "Would It Kill You to Stop Doing That: A Modern Guide to Manners." "That's the state of monomaniacal obliviousness that overcomes you when you're absorbed in an activity to the exclusion of everything else." Children now compete with their parents' devices for attention, resulting in a generation afraid of the spontaneity of a phone call or face-to-face interaction. Eye contact now seems to be optional, Dr. Turkle suggests, and sensory overload can often mean our feelings are constantly anesthetized. Researchers at the University of Michigan claim empathy levels have plummeted while narcissism is skyrocketing, with emotional development, confidence and health all affected

Researchers from Brown University and King's College London have uncovered new details about how brain anatomy influences language development in young kids. Using advanced MRI, they find that different parts of the brain appear to be important for language development at different ages. Their study, published in the Journal of Neuroscience, found that the explosion of language acquisition that typically occurs in children between 2 and 4 years old is not reflected in substantial changes in brain asymmetry. Structures that support language ability tend to be localized on the left side of the brain. For that reason, the researchers expected to see more myelin -- the fatty material that insulates nerve fibers and helps electrical signals zip around the brain -- developing on the left side in children entering the critical period of language acquisition. Surprisingly, anatomy did not predict language very well between the ages of 2 and 4, when language ability increases quickly. "What we actually saw was that the asymmetry of myelin was there right from the beginning, even in the youngest children in the study, around the age of 1," said the study's lead author, Jonathan O'Muircheartaigh, the Sir Henry Wellcome Postdoctoral Fellow at King's College London. "Rather than increasing, those asymmetries remained pretty constant over time." That finding, the researchers say, underscores the importance of environment during this critical period for language. While asymmetry in myelin remained constant over time, the relationship between specific asymmetries and language ability did change, the study found. To investigate that relationship, the researchers compared the brain scans to a battery of language tests given to each child in the study. The comparison showed that asymmetries in different parts of the brain appear to predict language ability at different ages. "Regions of the brain that weren't important to successful language in toddlers became more important i
