More than 35 million Americans are trying to quit smoking. Researchers reassure clinicians and their patients that varenicline, whose brand name is Chantix, is a safe and effective way to achieve smoking cessation and that failure to use this drug has caused preventable heart attacks and deaths from cardiovascular disease. Just a few months ago, the FDA removed the black box warning from varenicline.
Cognitive neuroscientists are using the Stampede supercomputer to provide accurate predictions of risk for those with depression and anxiety. They have been able to classify individuals with major depressive disorder with roughly 75 percent accuracy using a machine learning approach. Stampede 2 -- which will come online later in 2017 -- will provide the increased computer processing required to incorporate more data and achieve even greater accuracy.
Opioids have long been an important tool in the world of pain management, but the side effects of these drugs -- from addiction and respiratory failure to severe itching and dizziness, can be overwhelming. Scientists have been trying to understand how these side effects happen so they can create better, less problematic pain relievers.
The science and engineering workforce in the United States is aging rapidly, according to a new study. And it is only going to get older in coming years. Economists have found that the average age of employed scientists increased from 45.1 to 48.6 between 1993 and 2010, faster than the workforce as a whole.
An engineer is working to create a probiotic that would help protect the host from the negative health effects of adrenaline surges. The new probiotic could easily be mixed into yogurt or taken in pill form.
Around 100,000 Austrians suffer from Alzheimer's disease and 16,000 from Parkinson's. Experts estimate that, in view of the ageing population, these numbers are set to triple over the next 30 years. Both Alzheimer's and Parkinson's diseases are progressive degenerative diseases of the brain, which start up to 30 years before the onset of symptoms. Early diagnosis would be a huge help in combating the disease. However, the early detection tests that are available do not provide any reliable prediction about the further course of the disease and also carry the risk of producing a false positive result.
Scientists partially re-insulated ravaged nerves in mouse models of multiple sclerosis (MS) and restored limb mobility by treating the animals with a small non-coding RNA called a microRNA. In a new article, researchers report that treatment with a microRNA called miR-219 restarted production of a substance called myelin that is critical to normal function of the central nervous system.
Despite greater awareness of the dangers of prenatal exposure to alcohol, the rates of Fetal Alcohol Spectrum Disorders remain alarmingly high. This study evaluated academic achievement among children known to be prenatally exposed to maternal heavy alcohol consumption as compared to their peers without such exposure, and explored the brain regions that may underlie academic performance.
People exposed to entertainment television are more likely to vote for populist politicians according to a new study. The researchers investigated the political impact of entertainment television in Italy over the last 30 years during the phased introduction of Silvio Berlusconi's commercial TV network Mediaset.
Men are from Mars and women are from Venus? Whiles this stereotype is extreme and controversial, gender differences in behavior nonetheless are common in nature. Much variation in animal, including human, behavior is regulated by expression of hormones and their receptors in brains.
Brain size in primates is predicted by diet, an analysis by a team of anthropologists indicates. These results call into question “the social brain hypothesis,” which has posited that humans and other primates are big-brained due to factors pertaining to sociality.
The ability to remember sounds, and manipulate them in our minds, is incredibly important to our daily lives -- without it we would not be able to understand a sentence, or do simple arithmetic. New research is shedding light on how sound memory works, and is even demonstrating a means to improve it.
A researcher explores the different functions of prefabricated phrases in young learners' oral language production. These phrases provided learners with an instrument to overcome their lack of knowledge, to improve their fluency, and to enjoy some language play.
The common assumption about retail therapy is that it's all about indulging in things like pricey designer duds or the latest gadgets. But according to a new study, consumers are actually more likely to make practical purchases than splurge on luxury items when they feel less in control.
