Ten million third molars (wisdom teeth) are extracted from approximately 5 million people in the United States each year at an annual cost of over $3 billion. In addition, more than 11 million patient days of “standard discomfort or disability”—pain, swelling, bruising, and malaise—result postoperatively, and more than 11000 people suffer permanent paresthesia—numbness of the lip, tongue, and cheek—as a consequence of nerve injury during the surgery. At least two thirds of these extractions, associated costs, and injuries are unnecessary, constituting a silent epidemic of iatrogenic injury that afflicts tens of thousands of people with lifelong discomfort and disability. Avoidance of prophylactic extraction of third molars can prevent this public health hazard.
Arose may be a rose. But that rose-like fragrance in your perfume may be something else entirely, concocted from any number of the fragrance industry’s 3,100 stock chemical ingredients, the blend of which is almost always kept hidden from the consumer. Makers of popular perfumes, colognes and body sprays market their scents with terms like “floral,” “exotic” or “musky,” but they don’t disclose that many scents are actually a complex cocktail of natural essences and synthetic chemicals – often petrochemicals.
We have discovered distinctive red/gray chips in all the samples we have studied of the dust produced by the destruction of the World Trade Center. Examination of four of these samples, collected from separate sites, is reported in this paper. These red/gray chips show marked similarities in all four samples. One sample was collected by a Manhattan resident about ten minutes after the collapse of the second WTC Tower, two the next day, and a fourth about a week later. The properties of these chips were analyzed using optical microscopy, scanning electron microscopy (SEM), X-ray energy dispersive spectroscopy (XEDS), and differential scanning calorimetry (DSC).
It was a British citizen who, at the beginning, would model how to wage war in Israel. In the 1930s, when tension between the Arab people and the Jewish-Zionist community became a full-fledged civil war in Palestine - which had been under British rule since World War I - the fierce British officer Zionist Orde Wingate helped the Jews create a commando unit called Special Night Squads (SNS).
What do people think about when they think of Southern California? Hollywood is probably high on the list, with beaches and freeways close on its heels. Aerospace may not top the list, but it should. Aerospace was the dominant industry in Southern California for much of the twentieth century; only after the end of the Cold War did Hollywood pass aerospace as the main employer in the region. What did it mean to have these two major industries, aerospace and entertainment, in such proximity? At first glance they seem to have little in common: one appears technological, the other creative; one the child of government demand, the other of commercial appeal. But the two share an intertwined history, one that shaped Southern California—and the rest of our world—in surprising ways.
Synchrotron-based ν-XRF mapping and μ-FTIR microscopy enable to look into the fate and effects of tattoo pigments in human skin
In recent years, the seemingly unstoppable trend for tattoos has brought safety concerns into the spotlight1. Currently, basic toxicological aspects, from biokinetics to possible alterations of the pigments, are largely uncertain. The animal experiments which would be necessary to address these toxicological issues were rated unethical because tattoos are applied as a matter of choice and lack medical necessity, similar to cosmetics2. Consequently, the hazards that potentially derive from tattoos were as yet only investigated by chemical analysis of the inks and their degradation products in vitro3,4,5,6. Even though toxicological data might be available for some ink ingredients individually, information on in vivo interactions of the ink’s components and their fate within the body is rare.

There is increasing concern that most current published research findings are false. The probability that a research claim is true may depend on study power and bias, the number of other studies on the same question, and, importantly, the ratio of true to no relationships among the relationships probed in each scientific field. In this framework, a research finding is less likely to be true when the studies conducted in a field are smaller; when effect sizes are smaller; when there is a greater number and lesser preselection of tested relationships; where there is greater flexibility in designs, definitions, outcomes, and analytical modes; when there is greater financial and other interest and prejudice; and when more teams are involved in a scientific field in chase of statistical significance. Simulations show that for most study designs and settings, it is more likely for a research claim to be false than true. Moreover, for many current scientific fields, claimed research findings may often be simply accurate measures of the prevailing bias. In this essay, I discuss the implications of these problems for the conduct and interpretation of research.
The landscape of overt surveillance camera systems in public spaces has changed significantly since the introduction of the Protection of Freedoms Act 2012 and the Secretary of State’s Surveillance Camera Code of Practice 2013. An evolution and proliferation of new technologies and new capabilities create a dynamic challenge for regulators, policy makers and lawmakers. The risk potential for intrusion on citizens has significantly increased both by lawful operators of surveillance camera systems and those individual or State actors who seek to ‘hack’ in to systems. Cyber security has moved to the top of the security agenda.
