Intelligence is in the genes, researchers reported Tuesday in the journal Molecular Psychology. The international team, led by Ian Deary of the University of Edinburgh in Scotland and Peter Visscher of the Queensland Institute of Medical Research in Brisbane, Australia, compared the DNA of more than 3,500 people, middle aged and older, who also had taken intelligence tests.  They calculated that more than 40% of the differences in intelligence among...

The NCAA and its member institutions often refer to "student-athletes," but the front side of the term isn't often highlighted in a sports section. We asked officials from the Southland's 10 Division I universities to point us toward their best and brightest -- the teams that made classroom performance a priority. Eight of the schools chose to participate and here is what we found: -- Many of the best tennis players at the college level have been raised in hyper-competitive environments.

A healthier lifestyle may go a long way in reducing the risk of erectile dysfunction, a study finds, while another paper discovers that men who have the condition may also have a greater risk of cardiovascular disease. A meta-analysis published online Monday in the journal Archives of Internal Medicine looked at how lifestyle changes and medication to treat cardiovascular risks affected erectile dysfunction. In six studies that included 640 participants, four dealt with lifestyle changes, and two with the use of statins.

Airline mergers have put more than 70% of the nation's domestic traffic in the hands of four major carriers. But low-cost airlines still have some influence over airfares. A new study shows that when airlines such as JetBlue, Spirit, Frontier, Alaska and Southwest launch service on an existing domestic route, the average price from all carriers drops as much as 67%. It's good news for travelers, but aviation experts say most popular routes are still dominated by the four biggest carriers: United, Delta, Southwest and the soon-to-be-merged American and US Airways.

Acnemedications and treatments fill drug store shelves, but some acne sufferers may have a tough time discerning which are the best to use. A paper published online in the journal the Lancet finds that certain studies on acne remedies are few and far between. In a seminar in the journal researchers from the U.S. and the U.K. reviewed the current slate of treatments available, including topical treatments such as benzoyl peroxide, retinoids and topical antibiotics, and oral treatments such as antibiotics, contraceptives and isotretinoin (the last typically used to treat severe cases of acne)

Studies in macaques have for the first time shown that an intravaginal ring laced with an anti-HIV drug can block transmission of HIV during sexual intercourse. Researchers at the Population Council who demonstrated the product are now refining drug concentrations and contents of the ring and hope to begin human trials within 18 to 24 months. Previous studies with vaginal microbicides to block HIV have produced mixed results, with at least one showing some protection and another showing none.

Who ate the 364 million pounds of cultivated blueberries grown in the United States in 2009? Hopefully you did. The health benefits of blueberries have been touted for years, but two new studies, the Orlando Sentinel writes, underscore how the low-sugar fruit may help folks at risk of diabetes and high blood pressure. Arpita Basu, an Oklahoma State University nutritional sciences professor and lead author of a study published in the Journal of Nutrition, found a seven- to eight-point drop in the systolic blood pressure of 66 pre-hypertensive men and women who included a blueberry drink in their diet once a day for eight weeks.

Cesarean sections are often performed when a baby is going to be born early. Likewise, sometimes labor is induced when a woman's water breaks too early in the pregnancy. However, two new studies suggest that these common practices may, in fact, not benefit babies. Both papers, presented Thursday at the annual meeting of the Society for Maternal-Fetal Medicine, challenge conventional wisdom. The first looked at 2,560 babies delivered preterm because they were small for gestational age. The study found that those delivered by C-section before 34 weeks of pregnancy had 30% higher odds of developing respiratory distress compared with similar babies delivered vaginally.

As if Dr. Paul Offit hasn't made enough enemies  already by insisting (correctly) that parents put their kids' health at risk when they refuse to get them vaccinated, now the infectious disease expert appears to be picking a fight with those who believe in alternative therapies like prayer healing and acupuncture. In an essay to be published in Wednesday's edition of the Journal of the American Medical Assn., Offit questions the way the National Center for Complementary and Alternative Medicine doles out its $130-million annual budget.

Getting a colonoscopy is not something most people look forward to -- but a new analysis suggests that it's worth it to follow screening recommendations and have the test done every 10 years (or every five for those at high risk.) Writing in the New England Journal of Medicine on Wednesday, Harvard researcher Reiko Nishihara and co-authors assessed colonoscopy use, colorectal cancer cases and colorectal cancer deaths among participants in the multidecade Nurses' Health Study and Health Professionals Follow-up Study.

A government study on the effects of airline mergers found that flight cancellations and delays increased when competition on a route drops. The study by the U.S. Department of Transportation's inspector general was ordered by Congress in the wake of the proposal to merge American Airlines and US Airways into the world's largest air carrier. The study looked at delays and cancellation rates when the number of airlines serving a route dropped from three to two airlines. It looked at 32.2 million flights and flight performances from 70 U.S. airports.

People who took statins to lower their cholesterol levels ate more calories and fat in 2009-10 than did those who took them a decade earlier, raising the question of whether the drug provides a false sense of dietary security. Researchers who used data from a national health survey found that in 1999-2000, people who took statins ate fewer calories, by an average of 179 a day, and less fat than people who didn't take them. The differences began to shrink, and by 2005-06, the difference was insignificant.

In the wake of a $10-million payout to a whistleblower, UCLA's School of Medicine is drawing more scrutiny over its financial ties to industry and the possibility that they compromised patient care. A new study in this month's Journal of the American Medical Assn. raised a red flag generally about university officials such as Eugene Washington, the dean of UCLA's medical school who also serves on the board of healthcare giant Johnson & Johnson. The world's biggest medical-products maker paid Washington more than $260,000 in cash and stock last year as a company director.

The USC Shoah Foundation will expand its study of genocide by establishing a new center devoted to the study of mass killings and how such violent incidents begin, officials announced Friday. The foundation was started by film director Steven Spielberg on the set of his film "Schindler's List" and became part of USC in 2006. The foundation has collected more than 52,000 eyewitness testimonies of survivors of the Holocaust, Rwandan genocide and Nanjing Massacre.  The new group, called the Center for Advanced Genocide Research, will focus on resistance to mass killings and how the violence impacts emotional and physical behavior.

She had me at privyet . I had just delivered a talk in Romania on Jewish-Mormon relations (a niche topic, to be sure) at a church in Bucharest, and standing before me was Florina, a raven-haired beauty who greeted me in Russian after learning we had both lived in Moscow. Then she switched to English, which she had acquired as an au pair in London. I was a never-married bachelor in my early 40s and had begun to doubt that Miss Right and I would ever cross paths, much less during a speaking tour of Eastern Europe.

Take two slices of cherry pie and call me in the morning. OK. That's not quite the advice doctors are wont to give. But it might make at least a sliver of sense. Cherry pie contains the same sort of anti-inflammatory compounds as aspirin and other non-steroidal anti-inflammatory drugs - at least the cherries do. They're tart, or sour, cherries, which, as far as is known, contain more of these anti-inflammatory compounds than any other food, says Dr. Kerry Kuehl, assistant director of the Human Performance Laboratory at Oregon Health and Science University in Portland.

While your world shifts in previously unimaginable ways when you become a parent, one fundamental thing does not: You need a village to help you along. As a result, many new moms are seeking sanctuary and support in blogs and Facebook, according to a couple of recent studies. About 44% of new, first-time mothers spend more time on Facebook in the first nine months after childbirth compared with before, according to a study in the July issue of the Family Relations journal.

Very few shows could pull off a homage to the death of Philip Seymour Hoffman without seeming exploitative, sensational or culturally carnivorous. Only one could do it in the middle of an episode dealing with a bunch of missing anthrax and Garret Dillahunt as a dairy farmer. Two years ago, when CBS premiered the crime-procedural "Elementary," the decision to make Sherlock Holmes (played by Jonny Lee Miller) a modern-day recovering addict seemed equally canny and risky. Holmes is indeed literature's most famous and enduring druggie - in Nicholas Meyer's "Seven-Percent Solution" none other than Sigmund Freud helped him kick the coke habit.

A decade ago, as a foreign correspondent traveling through South America, I witnessed cellphone technology's march across the globe-- to a remote corner of the Peruvian Amazon, where even tricycle taxi drivers had them.   Now smartphone technology is completing its own conquest of the developing world. Handheld devices that allow you to browse the Web, or read a book, are now ubiquitous in South America, sub-Saharan Africa and the Indian subcontinent. This week, UNESCO reports on an unexpected consequence of the smartphone revolution: People with limited access to books are reading more, thanks to those tiny, portable screens.
