The Reading Brain in the Digital Age: The Science of Paper versus Screens E-readers and tablets are becoming more popular as such technologies improve, but research suggests that reading on paper still boasts unique advantages In a viral YouTube video from October 2011 a one-year-old girl sweeps her fingers across an iPad's touchscreen, shuffling groups of icons. In the following scenes she appear
Stone Age farmers lived through routine violence, and women weren't spared from its toll, a new study finds. The analysis discovered that up to 1 in 6 skulls exhumed in Scandinavia from the late Stone Age — between about 6,000 and 3,700 years ago — had nasty head injuries. And contrary to findings from mass gravesites of the period, women were equally likely to be victims of deadly blows, accordin
Can Eye Movements Treat Trauma?Recent research supports the effectiveness of "eye movement desensitization and reprocessing" Imagine you are trying to put a traumatic event behind you. Your therapist asks you to recall the memory in detail while rapidly moving your eyes back and forth, as if you are watching a high-speed Ping-Pong match. The sensation is strange, but many therapists and patients s
Booming population growth among the living, according to one rumor, outpaces the dead The human population has swelled so much that people alive today outnumber all those who have ever lived, says a factoid whose roots stretch back to the 1970s. Some versions of this widely circulating rumor claim that 75 percent of all people ever born are currently alive. Yet, despite a quadrupling of the popula
"Junk" DNA Holds Clues to Common DiseasesWith the new annotation of the human genome, researchers are finding that most of the code between genes is controlling crucial functions for life and health When the draft of the human genome was published in 2000, researchers thought that they had obtained the secret decoder ring for the human body. Armed with the code of 3 billion basepairs of As, Ts, Cs
With a presidential campaign, health care and the gun control debate in the news these days, one can't help getting sucked into the flame wars that are Internet comment threads. But psychologists say this addictive form of vitriolic back and forth should be avoided — or simply censored by online media outlets — because it actually damages society and mental health. These days, online comments "are
A Q&A with Ian Hacking on Thomas Kuhn's Legacy as "The Paradigm Shift" Turns 50 The seminal work on science's periodic upheavals may be more relevant to an earlier era Scientific American's review of Thomas Kuhn's The Structure of Scientific Revolutions in 1964 ended with the pat pronouncement that the book was "much ado about very little." The short piece, which appeared two years after the initi

Why Economic Models Are Always WrongFinancial-risk models got us in trouble before the 2008 crash, and they're almost sure to get us in trouble again When it comes to assigning blame for the current economic doldrums, the quants who build the complicated mathematic financial risk models, and the traders who rely on them, deserve their share of the blame. [See “A Formula For Economic Calamity” in t
Fukushima Nuclear Plant Released Far More Radiation Than Government SaidGlobal radioactivity data challenge Japanese estimates for emissions and point to the role of spent fuel pools The disaster at the Fukushima Daiichi nuclear plant in March released far more radiation than the Japanese government has claimed. So concludes a study1 that combines radioactivity data from across the globe to estima
Supercomputers can store more information than the human brain and can calculate a single equation faster, but even the biggest, fastest supercomputers in the world cannot match the overall processing power of the brain. And they are nowhere near as compact or energy efficient. Nevertheless, IBM is trying to simulate the human brain with its own cutting-edge supercomputer, called Blue Gene. For th
People think of many things, even numbers, as being either male or female Gender is so fundamental to the way we understand the world that people are prone to assign a sex to even inanimate objects. We all know someone, or perhaps we are that person, who consistently refers to their computer or car with a gender pronoun (“She’s been running great these past few weeks!”) New research suggests that
Female Ejaculation: The Long Road To Non-Discovery By Jesse Bering | Jun 17, 2011 04:01 PM Share Email Print I confess: this subject—the science of female ejaculation—is not an easy topic for me to write about. I could, in principle, feign complete gynaecological objectivity, affixing to my literary visage the stone-faced look of a caring urologist palpating your pudendum. But I suspect you know

Cupid's arrows, laced with neurotransmitters, find their marks Men and women can now thank a dozen brain regions for their romantic fervor. Researchers have revealed the fonts of desire by comparing functional MRI studies of people who indicated they were experiencing passionate love, maternal love or unconditional love. Together, the regions release neurotransmitters and other chemicals in the b
Twenty-five years after the tragic runaway fission and fire at Chernobyl, tons of concrete shield workers and visitors from the dangerously radioactive puddle of melted fuel that lurks in the basement of the building housing reactor No. 4. Similarly, more than 30 years after the partial meltdown at Three Mile Island in Pennsylvania, concrete shaved 2.5 centimeters deep guards a hollow reactor vess
Absolute Hero: Heike Onnes's Discovery of Superconductors Turns 100 [Slide Show] A century after the discovery of materials that conduct electricity without resistance, the applications remain disappointingly limited. That may be about to change On April 8, 1911, at the Leiden Cryogenic Laboratory in the Netherlands, Heike Kamerlingh Onnes and his collaborators immersed a mercury capillary in liqu
Nuclear Experts Explain Worst-Case Scenario at Fukushima Power PlantThe type of accident occurring now in Japan derives from a loss of off-site AC power and then a subsequent failure of emergency power on-site. Engineers there are racing to restore AC power to prevent a core meltdown First came the earthquake, centered just off Japan's east coast, near Honshu. The added horror of the tsunami quick

Egypt's revolution vindicates Gene Sharp's theory of nonviolent activism By John Horgan | Feb 11, 2011 03:15 PM | 1 Share Email Print Whereas most pundits have focused on the role of social media in Egypt's revolution, what impressed me most was that one of the most powerful, entrenched regimes in the world was toppled by a nonviolent uprising. Does anyone doubt that if the protestors had resorte
Long Live the Web: A Call for Continued Open Standards and Neutrality The Web is critical not merely to the digital revolution but to our continued prosperity—and even our liberty.
