Mutations in autism susceptibility gene increase risk in boys

Researchers at Emory University School of Medicine have identified five rare mutations in a single gene that appear to increase the chances that a boy will develop an autism spectrum disorder (ASD).

Mutations in the AFF2 gene, and other genes like it on the X chromosome, may explain why autism spectrum disorders affect four times as many boys as girls.

The mutations in AFF2 appeared in 2.5 percent (5 out of 202) of boys examined. Mutations in X chromosome genes only affect boys, who have one X chromosome. Girls have a second copy of the gene that can compensate.

Winemaking goes high-tech at the University of British Columbia

VANCOUVER, B.C. – July 11, 2012 – For centuries, people made wine by stomping grapes with their bare feet. But now, the art of winemaking is going high-tech at The University of British Columbia's Wine Research Centre.

Have you ever gotten a headache or a rash from a single glass of wine? Has one glass of Merlot or Shiraz resulted in a painful hangover? If yes, you may be one of the 30 percent of people who are allergic to compounds that are in some of the world's most popular wines.

Viruses linked to algae that control coral health

CORVALLIS, Ore. – Scientists have discovered two viruses that appear to infect the single-celled microalgae that reside in corals and are important for coral growth and health, and they say the viruses could play a role in the serious decline of coral ecosystems around the world.

Non-surgical treatment of common shoulder injury may increase chances of return-to-play

BALTIMORE, MD – Surgically repairing a painful shoulder injury in baseball players known as a SLAP tear (superior labral) varies widely and often doesn't allow for return to play at the same level as before the injury. However, researchers presenting their findings at the American Orthopaedic Society for Sports Medicine's Annual Meeting in Baltimore, Maryland suggest that nonsurgical treatment may be more beneficial.

HIV drug reduces graft-vs.-host disease in bone marrow transplant patients, Penn study shows

PHILADELPHIA -- An HIV drug that redirects immune cell traffic significantly reduces the incidence of a dangerous complication that often follows bone marrow transplants for blood cancer patients, according to research from the Perelman School of Medicine at the University of Pennsylvania that will be published today in the New England Journal of Medicine. The findings represent a new tactic for the prevention of graft-versus-host disease (GvHD), which afflicts up to 70 percent of transplant patients and is a leading cause of deaths associated with the treatment.

Anxiety linked to shortened telomeres, accelerated aging

BOSTON, MA—Is anxiety related to premature aging? A new study by researchers at Brigham and Women's Hospital (BWH) shows that a common form of anxiety, known as phobic anxiety, was associated with shorter telomeres in middle-aged and older women. The study suggests that phobic anxiety is a possible risk factor for accelerated aging.

The study will be electronically published on July 11, 2012 in PLoS ONE.

Menopausal hormone therapy associated with increased blood pressure

Menopausal hormone therapy use is associated with higher odds of high blood pressure, according to research published July 11 in the open access journal PLoS ONE. Longer hormone use was associated with further increased odds of high blood pressure, although this association decreased with subjects' ages.

The authors of the study, led by Joanne Lind of the University of Western Sydney, included 43,405 postmenopausal women in their study to identify the association.

It's not just lunch

Sharing a meal with a former romantic partner is more likely than other, non-food-related activities to make your current partner jealous, according to a study published July 11 in the open access journal PLoS ONE.

Personalized genomic medicine faces many hurdles

When the human genome project was completed in 2003, some expected it to herald a new age of personalized genomic medicine, but the resulting single "reference" sequence has significant shortcomings for these applications and does not account for the actual variability in the human population, as reported in a study published July 11 in the open access journal PLoS ONE.

Ancient domesticated remains are oldest in southern Africa

Researchers have found evidence of the earliest known instance of domesticated caprines (sheep and goats) in southern Africa, dated to the end of the first millennium BC, providing new data to the ongoing debate about the origins of domestication and herding practices in this region. The full results are published July 11 in the open access journal PLoS ONE.

Eye movement direction not correlated with lying

New research refutes a commonly held belief that certain eye movements are associated with lying. The idea that looking to the right indicates lying, while looking left suggests truth telling, is shown to be false in a report published July 11 in the open access journal PLoS ONE. The researchers, led by Caroline Watt of the University of Edinburgh, completed three different studies to show that there was no correlation between the direction of eye movement and whether the subject was telling the truth or lying.

NIST issues guidance for pediatric electronic health records

The National Institute of Standards and Technology (NIST) has released a guide to help improve the design of electronic health records for pediatric patients so that the design focus is on the users—the doctors, nurses and other clinicians who treat children.

Fossil turtle from Colombia round like car tire

Paleontologist Carlos Jaramillo's group at the Smithsonian Tropical Research Institute in Panama and colleagues at North Carolina State University and the Florida Museum of Natural History discovered a new species of fossil turtle that lived 60 million years ago in what is now northwestern South America. The team's findings were published in the Journal of Paleontology.

NIST updates guidelines for mobile device security

The National Institute of Standards and Technology (NIST) has released a proposed update to its guidelines for securing mobile devices—such as smart phones and tablets—that are used by the federal government. NIST is asking for public comment on the draft document.

High-density lipoprotein still matters, look at the particles!

Boston, MA—Until recently, it seemed well-established that high-density lipoprotein (HDL) is the "good cholesterol". However there are many unanswered questions on whether raising someone's HDL can prevent coronary heart disease, and on whether or not HDL still matters.
