What Americans Fear Most Isn't Ebola Or Terrorism, It's...

Science2.0 - October 21, 2014 - 8:29pm

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:

By Adam Winstock, King's College London

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.

Hunters Unite: Global Warming Implicated In Animal Size

Science2.0 - October 21, 2014 - 3:14pm

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.

Great Earthquakes Doubled In The Most Recent 10 Year Period - What That Means

Science2.0 - October 21, 2014 - 3:05pm

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.

Viral Mutation: Why You May Be More Susceptible To Last Year's Flu

Science2.0 - October 21, 2014 - 2:54pm

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.

Egg Donors: Do Parents Prefer Beauty, Brains Or Health?

Science2.0 - October 21, 2014 - 2:46pm
Sperm donation for fertility issues has been common for some time and ovum donation has become increasingly accepted by women as well.

That leads to sociological questions about selection; everyone says they will love their kids no matter what, but given a book to choose from, what traits in a donor do people consider most important, beauty, intelligence or health?

Children Who Drink Milk Substitutes Have Lower Vitamin D - But Why?

Science2.0 - October 21, 2014 - 2:29pm

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

The Optimism Of Depressed People

Science2.0 - October 21, 2014 - 1:56pm

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.

Government Math: More Will Lose Health Insurance Than Gained It If ACA Subsidies Are Eliminated

Science2.0 - October 21, 2014 - 7:06am

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.

Seasonal Affective Disorder - Depression Linked To Serotonin

Science2.0 - October 21, 2014 - 12:00am

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.

Dopamine Receptor Agonist Drugs Linked To Gambling And Hypersexuality

Science2.0 - October 20, 2014 - 10:18pm

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.

HPV Vaccine Does Not Cause Multiple Sclerosis

Science2.0 - October 20, 2014 - 10:01pm

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.
