Autism and Air Pollution: New Study Bolsters Suspected Link. Pregnant women may nearly double their risk of giving birth to a child with autism by inhaling smog spewed by vehicles or smoke stacks, according to a new Harvard study that could help unlock the deepest autism mysteries.

Autism and Air Pollution: New Study Bolsters Suspected Link

The research, released Thursday, fortifies previous scientific findings that linked air pollution to autism. And it offers fresh insights by showing women in their third trimesters seem most vulnerable if they breathe in elevated levels of tiny airborne particles emitted by power plants, fires and automobiles.

The association between discontinuing hormonal contraceptives and wives’ marital satisfaction depends on husbands’ facial attractiveness

C. Gaulin, University of California, Santa Barbara, CA, and accepted by the Editorial Board October 16, 2014 (received for review August 1, 2014) Significance Hormonal contraceptives (HCs) are believed to suppress biological processes associated with women’s preferences for cues of partner genetic fitness, cues that may be summarized by men’s facial attractiveness. Researchers make blood vessels grow by shining a light on skin. Any fan of Star Trek knows that simply shining light on an injury will heal many wounds in the future.

Researchers make blood vessels grow by shining a light on skin

Now scientists have brought that future a bit closer. In a new study, researchers have found a way to stimulate the growth of blood vessels—an important part of healing—by hitting the skin with ultraviolet light. In the past decade, scientists have used light to manipulate the chemistry of cells in a dish—but they’ve struggled to do the same in living organisms. “There are hundreds of different types of cells; you have a lot more other biological molecules present,” says bioengineer Andrés García of the Georgia Institute of Technology in Atlanta.

So García and colleagues turned to a water-based gel, or hydrogel, impregnated with a molecule called RGD peptide. Marijuana And Cancer: Scientists Find Cannabis Compound Stops Metastasis In Aggressive Cancers. A pair of scientists at California Pacific Medical Center in San Francisco has found that a compound derived from marijuana could stop metastasis in many kinds of aggressive cancer, potentially altering the fatality of the disease forever.

Marijuana And Cancer: Scientists Find Cannabis Compound Stops Metastasis In Aggressive Cancers

"It took us about 20 years of research to figure this out, but we are very excited," said Pierre Desprez, one of the scientists behind the discovery, to The Huffington Post. "We want to get started with trials as soon as possible. " The Daily Beast first reported on the finding, which has already undergone both laboratory and animal testing, and is awaiting permission for clinical trials in humans.

Desprez, a molecular biologist, spent decades studying ID-1, the gene that causes cancer to spread. Meanwhile, fellow researcher Sean McAllister was studying the effects of Cannabidiol, or CBD, a non-toxic, non-psychoactive chemical compound found in the cannabis plant. Paul Ryan’s budget flimflam.

Money in the House elections, in 8 charts

With just over a month before the election, the general consensus is that Democrats will have a tough time picking up the 25 seats they need to win back the house, despite some protestations. But when it comes to the money, Republicans appear to be in solid shape. Jon Stewart Rails Against Fox News' Hypocritical Coverage Of School Lunch Changes. On Thursday night's "Daily Show," Jon Stewart did not hold back his feelings about Fox News' vilification of Michelle Obama for -- dun dun dun -- encouraging children to eat healthier.

Jon Stewart Rails Against Fox News' Hypocritical Coverage Of School Lunch Changes

The First Lady has made curbing childhood obesity her pet cause during her time in the White House, and part of that agenda included the USDA updating public school cafeteria recommendations to include (slightly) healthier options. Cue the Fox News outrage, because, why not attack each and every thing the Obamas do? Jon wasn't about to let Fox's pundits off the hook. "Why is this news?! " 63,000-Year-Old Modern Human Skull Found in Laos. According to an international team of anthropologists, an ancient skull collected from a cave in the Annamite Mountains in northern Laos is the oldest modern human fossil found in Southeast Asia.

63,000-Year-Old Modern Human Skull Found in Laos

The skull pushes back the clock on modern human migration through the region by as much as 20,000 years and indicates that ancient humans out of Africa left the coast and inhabited diverse habitats much earlier than previously appreciated. The scientists, who found the skull in 2009, were likely the first to dig for ancient bones in Laos since the early 1900s, when a team found 16,000-year-old skulls and skeletons of several modern humans in another cave in the Annamite Mountains. “It’s a particularly old modern human fossil and it’s also a particularly old modern human for that region,” said Dr Laura Shackelford, anthropologist at the University of Illinois and co-author of the study published in the Proceedings of the National Academy of Sciences.

Greek police send crime victims to neo-Nazi 'protectors' Greece's far-right Golden Dawn party is increasingly assuming the role of law enforcement officers on the streets of the bankrupt country, with mounting evidence that Athenians are being openly directed by police to seek help from the neo-Nazi group, analysts, activists and lawyers say.

Greek police send crime victims to neo-Nazi 'protectors'

In return, a growing number of Greek crime victims have come to see the party, whose symbol bears an uncanny resemblance to the swastika, as a "protector". One victim of crime, an eloquent US-trained civil servant, told the Guardian of her family's shock at being referred to the party when her mother recently called the police following an incident involving Albanian immigrants in their downtown apartment block.

"They immediately said if it's an issue with immigrants go to Golden Dawn," said the 38-year-old, who fearing for her job and safety, spoke only on condition of anonymity. Is Sitting Killing Me? Autism-Pesticide Link Found in Calif. Study. A California study out Monday found that pregnant women who live near farms where pesticides are applied had a two-thirds higher risk of having children with autism.

Autism-Pesticide Link Found in Calif. Study

The findings in the journal Environmental Health Perspectives examine the association between living near commercial pesticide applications and having offspring with autism, but do not show cause-and-effect. Autism is a neurodevelopmental disorder that ranges in severity and has been on the rise in recent years. Spinal cord research offers unexpected hope to people with paralysis. Susan Harkema was sending electricity down broken spinal cord to study nerve pathwaysShe was the one who got a shock when her patient called out: "I can move my toe!

"Harkema: First time stimulation directly to spinal cord has shown voluntary activityTechnique is another piece of the puzzle toward helping paralyzed people walk again (CNN) -- At her research lab at the University of Louisville, neuroscientist Susan Harkema turned her back to her study subject to check a reading on a computer screen. Being gay may be in the DNA, researchers say. 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 for the Advancement of Science conference. Researchers don’t know which of the specific genes in the two links of DNA are key to the formation and development of sexual orientation, The Daily Mail reported.

But they also do much, much more. Middle-Aged Men, Too, Can Blame Estrogen for That Waistline. Bacterial toxins cause deadly heart disease: Superantigens produced by staph bacteria are required for deadly effects of infective endocarditis and sepsis. University of Iowa researchers have discovered what causes the lethal effects of staphylococcal infective endocarditis -- a serious bacterial infection of heart valves that kills approximately 20,000 Americans each year. According to the UI study, the culprits are superantigens -- toxins produced in large quantities by Staphylococcus aureus (staph) bacteria -- which disrupt the immune system, turning it from friend to foe.

"The function of a superantigen is to 'mess' with the immune system," says Patrick Schlievert, Ph.D., UI professor and chair of microbiology at the UI Carver College of Medicine. "Our study shows that in endocarditis, a superantigen is over-activating the immune system, and the excessive immune response is actually contributing very significantly to the destructive aspects of the disease, including capillary leakage, low blood pressure, shock, fever, destruction of the heart valves, and strokes that may occur in half of patients.

" PTSD may be prevented, researchers find. Experts estimate that up to 20% of U.S. troops returning from Iraq and Afghanistan suffer from post-traumatic stress disorder , a condition that can be stubbornly difficult to treat. But what if PTSD could have been prevented in the first place? Scientists have done something similar in traumatized mice. Days after a harrowing experience being restrained on wooden boards, they were given a drug that triggers a brain receptor thought to be involved in how mice — and people — respond to fear. "We prevented PTSD-like symptoms," said Emory University neuroscientist Raul Andero Gali, lead author of a study published Wednesday in the journal Science Translational Medicine. The study raises the possibility that similar drugs could one day be given to people after combat, car accidents or other types of trauma.
