        Schizophrenia, which affects 1 in 100 people
        worldwide and an estimated 2.4 million
        Americans, exacts tremendous social costs and
        great human suffering. Drugs can calm the inner voices,
        delusions and hallucinations, but few patients recover
        fully, and there is no cure. Nor are there predictive
        tests or internal markers for the disease — it must be
        diagnosed by outward signs alone.
        But this problem is at last yielding
        to progress on the genetic front.
        In July, an international
        consortium of schizophrenia
        researchers, mounting what
        it calls the largest biological
        experiment in the history of
        psychiatry, reported 108 regions
        in the genome associated with
        schizophrenia. Two dozen of
        these genetic links had been
        recorded before, but more than
        80 were new. Neuroscientists
        now have many more avenues
        for exploring the biologi ... Detalii... »

        What Made the Bang so Big?

        Earlier in 2014, cosmologists
        thought they were finally
        closing in on an answer
        to that age-old question, “How
        did it all begin?” In March,
        Harvard astrophysicist John Kovac
        announced that a small telescope
        at the South Pole called BICEP2
        (short for Background Imaging of
        Cosmic Extragalactic Polarization)
        had captured signals that apparently
        come from “the first trillionth of a
        trillionth of a trillionth of a second
        in the history of the universe.”
        Independent confirmation was
        still needed, said Kovac, who heads
        the BICEP2 team, but if the result
        held up, it would mean scientists were on the verge of
        witnessing and understanding the moment of creation
        for our cosmos. Then data from the European Space
        Agency’s Planck space telescope rolled in six months later,
        casting doub ... Detalii... »

        As you look over the recent incidents, what do they tell you about the state of our cybersecurity?

        The Home Depot and Target breaches were examples of how our commercial infrastructure is very vulnerable to those who want to exploit it. As criminals increase their sophistication, they will pick bigger and more complex targets. That targeting won’t be for the intellectual challenge — it will be because bigger targets have more to offer. Theft of millions of credit card transactions provides a huge body of information to break up and resell to other criminals. Theft of medical data, design and marketing plans, and financial information is a growing business with little in the way to discourage it. It took months before the Home Depot and Target breaches were detected. It took more time before the companies patched their software, then assured customers that the patched systems were safe. Can we really trust that ... Detalii... »

        THE VUITTON WENT BOOM

        The vast majority of terror killings on airlines are by bombs hidden in checked luggage. To date, less than half of all checked baggage (and almost no cargo) is screened for explosives.
        El Al Airlines, with the world’s most efficient security, is often consulted for anti-terror advice. In 1987 an Israeli expert drafted a thorough security plan for Pan American Airways. It involved profiling passengers, hiring only professional security staff (not minimum-wage high school dropouts), and carefully inspecting all carry-on items, checked baggage, and hold cargo.
        The company rejected the idea as “overly expensive” and “intrusive to passengers.” A year later, Pan Am Flight 103 exploded over Lockerbie, Scotland—from a bomb in unin

        spected checked baggage. Pan Am soon after went out of business.
        As long as airlines continue to gamble with passengers’ safety just for the sake of stockholders’ dividends, we are all in d ... Detalii... »

        I think arriving at or departing from any airport in America is just horrendous these days.

        Anyone who travels by air has good reason to be concerned. Besides post-9/11 jitters, we increasingly hear reports of flaws in the air traffic system, overworked flight controllers, computer failures at peak traffic hours, near misses in the air and on the ground.
        One carefully underreported threat (don’t panic the customers) is shoulder-fired surface-to-air missiles—easy to operate, inexpensive, and readily available—presently impossible for civilian airliners to defend against. Our airplanes are, if not sitting, at least slow-flying ducks for terrorists.
        Cited again and again is incompetence at all levels of the agencies tasked with aviation security. Most “security measures” supposedly in place to protect air travelers are highly cosmetic. Officials at the highest levels proclaim that “the government is doing everything in its power to counter terrorism.” We hope that this brief review of airport ... Detalii... »
