In 2005, John Ioannidis wrote a paper in PLOS Medicine showing that most published research findings are false.
What makes Americans afraid is the topic of the first comprehensive nationwide study by Chapman University. According to the Chapman poll, the number one fear in America today is not Muslim terrorists or Russian imperialism or Ebola, it's...walking alone at night.
The Chapman Survey on American Fears included 1,500 nationally representative participants. The top five things Americans fear the most are:

Despite the language we use about drugs, many people don’t see themselves as “drug users” but as rational adults who aren’t on a mission to seek moral disintegration and cause themselves harm.
People who use drugs are just people who happen to use drugs (they might also do yoga, go the cinema, get degrees, litter the streets or be into base-jumping) – normal people who care about their loved ones, their health and well-being and want to make the most of that wonderful thing that we all share: life.

The #20 Million Memorial created earlier this month by the United States Centers for Disease Control, is an online tribute to honor the 20 million spouses, mothers, fathers, children, sisters, brothers, and friends who have died of tobacco-related diseases since 1964.-->
Fewer cords, smaller antennas and quicker video is the goal of a microwave circuit that has set a new world record for data transmission.
Alpine goats appear to be shrinking in size, according to scholars at Durham University, and that is due to global warming over the past 30 years, they say.
Young Chamois now weigh about 25 percent less than animals of the same age in the 1980s, they found, and note that in recent years, decreases in body size have been identified in a variety of animal species and have frequently been linked by other scholars to changing climate.
Since December 2004 there have been 18 quakes of 8.0 or greater on the moment magnitude (Mw) scale – a rate more than twice that seen from 1900 to mid-2004.
Some of that difference could be due to unprecedented advances in technological and scientific capacity to detect earthquakes. Like the distance of Babe Ruth's homeruns, anecdotes about past earthquakes have the mist of legend shrouding them, but modern earthquakes have a variety of ways they can be understood - and that helps recalibrate risk for future earthquakes.
Why were so many middle-aged adults hit especially hard by the H1N1 influenza virus during the 2013-2014 influenza season?
Vaccines work by stimulating the immune system to produce antibody proteins against particles (called antigens) from an infectious agent, such as bacteria or a virus. The immune system saves the cells that produce effective antibodies, which then provide immunity against future attacks by the same or similar infectious agents. Seasonal influenza typically kills 36,000 Americans, alone, and nearly 500,000 individuals around the world each year.
Some children are allergic to milk, so they drink milk substitutes such as soy or rice. And almond milk has become a well-marketed fad to due health claims.
But there may be negatives: though many of those products are fortified, children who drink them have lower levels of Vitamin D in their blood than those who drink cow's milk, according to a paper in the Canadian Medical Association Journal.
Even depressed people are essentially optimistic - they believe that tomorrow will be better, even though that belief probably won't lead to better outcomes. That is true optimism.
A paper in Clinical Psychological Science says that middle-aged adults who had a history of depression evaluated their past and current lives in more negative terms than adults without depression - but the future was just as rosy in both groups.
Eliminating subsidies that help low- and moderate-income people purchase coverage through government-run health insurance marketplaces would sharply boost costs for consumers and cause more than 11 million Americans to lose their health insurance, according to a new paper by the section of the RAND Corporation devoted to nationalizing health care.
A paper presented at the annual congress of the European College of Neuropsychopharmacology (ECNP) in Berlin says that moderate cannabis use by adolescents does not lead to educational or intellectual decline, but that heavy cannabis use is associated with slightly poorer exam results at age 16.
Some people suffer from 'winter blues' while others have no issue.
Seasonal Affective Disorder (SAD)
affects people as daylight levels drop in autumn. At Northern European latitudes (for example all of Scandinavia, Glasgow and Moscow) around 1 person in 6 suffers from SAD.
Psychologists have searched for reasons why. A small longitudinal study concluded that people with Seasonal Affective Disorder show significant seasonal differences in the way they regulate the neurotransmitter serotonin in comparison to the majority of the population.
Can probiotic yogurt help with lupus?
While most of science disagrees, corporate marketing departments have embraced every chance to imply their product helps with digestion and whatever else can sell product. A new paper in Applied and Environmental Microbiology adds to that, finding that Lactobacillus species, commonly seen in yogurt cultures, correlate in the guts of mouse models, with mitigation of lupus symptoms, while Lachnospiraceae, a type of Clostridia, correlate with worsening.
Unusual and severe impulse control disorders, including pathological gambling, hypersexuality and compulsive shopping, have been reported in patients taking dopamine receptor agonist drugs. Dopamine receptor agonist drugs, which activate the dopamine receptors, are commonly prescribed and there were 2.1 million dispensed outpatient prescriptions in the fourth quarter of 2012.
To find answers, the authors analyzed adverse drug event reports for six dopamine receptor agonist drugs marketed in the U.S. Their analysis was based on 2.7 million domestic and foreign adverse drug event reports from 2003 to 2012 pulled from the U.S. Food and Drug Administration's Adverse Event Reporting System database.
Vaccines have been associated with autism and various other conditions and diseases. Most recently, the hepatitis B (HepB) and human papillomavirus (HPV) vaccine has been linked to increased risk of multiple sclerosis (MS) and other acquired central nervous system demyelinating syndromes (CNS ADS).
A study to seek answers found no long-term association of vaccines with disease and short-term increased risk in younger patients was likely resulted from existing disease, write authors Annette Langer-Gould, M.D., Ph.D., of Kaiser Permanente, Southern California, Pasadena, and colleagues.
New geochemical tracers can identify any hydraulic fracturing flowback fluids that could have spilled into the environment, according to field tests at a spill site in West Virginia and downstream from an oil and gas brine wastewater treatment plant in Pennsylvania.
