Adult female cercopithecines have long been known to bias their social behaviour towards close maternal kin. However, much less is understood about the behaviour of paternal kin, especially in wild populations. Here, we show that wild adult female baboons bias their affiliative behaviour towards their adult paternal half-sisters in the same manner and to(More)
European Neurosciences conference in Amsterdam in July, researcher Ken McCarthy takes the stage to give his presentation. He sports a black shirt and jeans, and his strong cheekbones, shock of white hair and tanned skin give him the look of a film star. But he doesn’t have the confidence to match. “I find this a little bit daunting,” he says, as he(More)
Afghanistan 22.5% 0.16 This war-torn country reports the world’s highest prevalence of depression, and yet it is among the least equipped to deal with it. Con ict is a well-established risk factor for depression, as are child sexual abuse and domestic violence. China 3.02% 1.53 The relatively low prevalence of depression in China could be the result of the(More)
Brain disorders cost Europe almost €800 billion (US$1 trillion) a year — more than cancer, cardiovascular disease and diabetes put together. That’s the conclusion of a report commissioned by the European Brain Council that provides the most comprehensive assessment of the financial consequences of mental ailments so far. The report’s authors argue that(More)
The substance causing the peculiar odor in sweat of schizophrenic patients has been isolated and identified as trans-3-methyl-2-hexenoic acid by gas chromatography, mass spectrometry, and nuclear magnetic resonance spectroscopy. The natural and the synthetic compounds were cleaves across the double bond to give 2-pentanone and oxalic acid, thereby(More)
In 2007, Haynes, a neuroscientist at the Bernstein Center for Computational Neuroscience in Berlin, put people into a brain scanner in which a display screen flashed a succession of random letters. He told them to press a button with either their right or left index fingers whenever they felt the urge, and to remember the letter that was showing on the(More)
For volunteers, a brain-scanning experiment can be pretty demanding. Researchers generally ask participants to do something — solve mathematics problems, search a scene for faces or think about their favoured political leaders — while their brains are being imaged. But over the past few years, some researchers have been adding a bit of down time to their(More)
Metallothioneins (MTs) are low molecular weight, heavy metal binding proteins unique in their high cysteine content and high affinity for Zn2+, Cd2+, Hg2+, Ag2+ and Cu2+ (refs 1--3). The synthesis of MTs is induced by zinc or cadmium in the liver and kidney and in cultured cells. More recently MT induction by the steroid hormone dexamethasone (Dex) has been(More)
