According to a study from the National Bureau of Economic Research, about 20 percent of the population is attracted to their own gender. That’s nearly double the usual estimates of about 10 percent. The authors explain that their methodology might have something to do with it: Participants were randomly assigned to either a “best practices method” that was computer-based and provides privacy and anonymity, or to a “veiled elicitation method” that further conceals individual responses. Answers in the veiled method preclude inference about any particular individual, but can be used to accurately estimate statistics about the population. Comparing the two...

Researchers say they’ve found more DNA evidence that possibly shows gay men don’t have a choice — that their biological makeup drives them to homosexuality. In a study at Chicago University, researchers looked at DNA chains of 400-plus pairs of gay brothers and found what they said were two distinct bits of genetic material that they claim are linked to homosexuality, The Daily Mail reported. The gay brothers were identified and recruited to help with the study over the course of several years’ worth of Gay Pride festivals and marches. The research was highlighted during the recent annual American Association...

It turns out clues about a person’s identity and ethnicity can come from a surprising source: earwax. Researchers from the Monell Chemical Senses Center in Philadelphia decided to analyze earwax as a possible source of personal information based on previous studies in which researchers analyzed underarm odor to unlock clues about a person’s identity. "Our previous research has shown that underarm odors can convey a great deal of information about an individual, including personal identity, gender, sexual orientation and health status," study author George Preti, an organic chemist at Monell, said in a press release. "We think it possible that...

The word “pseudoscience” is used to describe something that is portrayed as scientific but fails to meet scientific criteria. This misrepresentation occurs because actual science has creditability (which is to say it works), and pseudoscience attempts to ride on the back of this credibility without subjecting itself to the hard intellectual scrutiny that real science demands. A good example of pseudoscience is homoeopathy, which presents the façade of a science-based medical practice but fails to adhere to scientific methodology. Other things typically branded pseudoscience include astrology, young-Earth creationism, iridology, neuro-linguistic programming and water divining, to name but a few.

Another insane cold wave — not the infamous “polar vortex ” but its evil twin — is bringing sub-zero and single-digit temperatures to much of the nation. And global warming may be even more extreme, and potentially more catastrophic, than climate scientists had feared. This is, of course, no contradiction. The rallying cry of the denialists — “It’s really cold outside, so global warming must be a crock!” — can be taken seriously only by those with a toddler’s limited conception of time and space. They forget that it’s winter, and apparently they don’t quite grasp that even when it’s...

David Remnick of The New Yorker showed up on PBS’s Charlie Rose Monday night to discuss his long, mostly sympathetic profile of Barack Obama from the January 27 issue of the magazine. Near the end of the interview, Rose focused in on the president’s reported desire to be “big.” The host wondered, “[W]hat's his definition of 'big,' and does he believe in his deep recesses of his own mind that the chance of that has slipped away?” Remnick replied that no, Obama does not think his chance of being “big” has slipped away. The editor then rattled off a laundry...

While the planet's surface temperatures over the past century have risen to unprecedented levels, records have shown a slowdown in the pace of warming over the past 15 years. Scientists have proposed several theories of natural climate variability and heat redistribution that may have contributed to the slowdown to varying degrees. A new study, however, suggests that the slowdown itself may be a mirage — the result of temperature records that have considerably underestimated the pace of warming since 1997. The global coverage of temperature measurements is incomplete, and that can cause biases in temperature records — research datasets deal...

The next time you hear someone dispute that human activity is destabilizing our climate, remember this pie chart. It represents geochemist James Lawrence Powell's review of 2,258 peer-reviewed scientific articles about climate change, written by 9,136 authors, published between Nov. 12, 2012 and December 31, 2013. Of all those hundreds of papers and thousands of researchers, Powell found one article, authored by a single scientist, that attributed climate change to something other than human actions: "The Role of Solar Activity in Global Warming," by S.V. Avakyan, appearing in the Herald of the Russian Academy of Science, Vol. 83, No. 3....

COLLEGE PARK, Md. (CBSDC) – Accelerated aging and a greater likelihood of suffering from an age-related illness at a younger age are two consequences being linked to African-American men who have experienced high-levels of racism throughout their lives. A study published in the American Journal of Preventive Medicine finds that African-American men who reported high levels of racial discrimination, or who have internalized anti-black attitudes, have an increased risk of premature death and chronic disease than white people. Previous research has documented African-Americans’ shorter life expectancy and greater risk of chronic diseases, but this new study is the first to...

If your New Year’s resolution is to change your light bulbs, don’t worry—the federal government’s here to help. Beginning January 1, 2014, the federal government will ban the use of 60-watt and 40-watt incandescent light bulbs. The light bulb has become a symbol in the fight for consumer freedom and against unnecessary governmental interference into the lives of the American people. 2007, Congress passed and President George W. Bush signed into law an energy bill that placed stringent efficiency requirements on ordinary incandescent bulbs in an attempt to have them completely eliminated by 2014. The law phased out 100-watt and...

In addition to my career as a PhD chemist, I am one of a select few who enjoy the privilege of moderating content on reddit.com’s science forum. The science forum is a small part of reddit, but it nonetheless enjoys over 4 million subscribers. By comparison, that’s roughly twice the circulation of The New York Times. The forum, known as /r/science, provides a digital space for discussions about recent, peer-reviewed scientific publications. This puts us (along with /r/AskScience) on the front line of the science-public interface. On our little page, scientists and nonscientists can connect through discussions on everything from...

Geographers from Kansas State University have created a map of the spatial distribution of the Seven Deadly Sins across the United States. How? By mapping demographic data related to each of the Sins. Below are screenshots of the maps in standard deviation units; red naturally is more sinful, blue less sinful.

The human species began as the hybrid offspring of a male pig and a female chimpanzee, a leading geneticist has suggested. The startling claim has been made by Eugene McCarthy, of the University of Georgia, who is also one of the worlds leading authorities on hybridisation in animals. He points out that while humans have many features in common with chimps, we also have a large number of distinguishing characteristics not found in any other primates. Dr McCarthy says these divergent characteristics are most likely the result of a hybrid origin at some point far back in human evolutionary history....

(CNN) -- Mom-to-be Maggie Baumann knew she most definitely would not be "eating for two." She couldn't. During her first pregnancy, she was extremely preoccupied with just how many calories she consumed and stuck to a very strict exercise routine. "Getting on the scale at the doctor's office was very triggering for me," said Baumann of Newport Beach, California, who is now an eating disorders specialist and trauma therapist who devotes some of her practice to pregnant women and moms suffering from eating disorders. She gained 32 pounds during her first pregnancy, which is very much in line with the...

After certain press criticism and a productive online backlash in the blogosphere, the American Psychiatric Association (APA) is performing a gratifying volte-face in its use of the term sexual "orientation" for paedophilia. In its fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), the APA has distinguished between paedophilic disorder and paedophilic orientation. Paedophilia-advocacy groups, like B4U-ACT, a grassroots lobby group, have long seen the declassification of paedophilia to the status of an "orientation" for “minor-attracted persons" (MAPs) to be a necessary means to their ends. The North American Man-Boy Love Association (and numerous international affiliates advocating...

I was perusing through the news and saw many articles on the horrific destruction the storm in the Philippines had wrought. As I reading through the stories at Google, yahoo News, the term 'Climate Negotiator' kept on appearing in article after article. Well, I had no idea what a Climate Negotiator is, does. I mean, trying to negotiate with the climate seems a sissyphean task if not the most mentally stable thing to attempt. I tried searching Google, Yahoo for some precise meaning, job description for a Climate Negotiator but information was far and few between. It seems it is...

(AP) FDA to ban artery-clogging trans fats By MARY CLARE JALONICK Associated Press WASHINGTON Heart-clogging trans fats have been slowly disappearing from grocery aisles and restaurant menus in the last decade. Now, the Food and Drug Administration is finishing the job. The FDA announced Thursday it will require the food industry to gradually phase out artificial trans fats, saying they are a threat to people's health. Commissioner Margaret Hamburg said the move could prevent 20,000 heart attacks and 7,000 deaths each year.

The American Psychiatric Association’s (APA) decision to once again reclassify pedophilia has led to further concerns that the professional organization is attempting to legitimize the disorder, paving the way for its defense and the recommendation of removal of age-of-consent laws.In a press release Friday, Liberty Counsel, a nonprofit organization that promotes the causes of religious liberty, the sanctity of human life, and the family observed that in its newly published Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), APA “changed the classification of pedophilia from a ‘disorder’ to a ‘sexual orientation,’ but, following the public outcry, APA released...

Ellmers: But men are required to purchase maternity coverage. Sebelius: Well, an insurance policy has a series of benefits whether you use them or not… Ellmers: And that is why health care premiums are increasing, because we are forcing them to buy things that they will never need. Thank you. Sebelius: The individual policies cover families. Men often do need maternity care for their spouses and for their families, yes. Ellmers: A single male, aged 32, does need maternity coverage. To the best of your knowledge, has a man ever delivered a baby?
