Genome Breakthrough Zeroes In on Disease

New approach decodes entire genomes of individual patients

(Newser) - Two teams of researchers have identified the exact genetic cause of their patients' rare diseases by sequencing their entire genomes, a sharp but promising departure of the previous application of genetics to disease. “I suspect that in the next few years human genetics will finally begin to systematically deliver...

Stressed Men Go for Novelty in Sex Partners

Men suddenly choose women who don't look like them

(Newser) - Men who are under stress choose different women as sex partners than they do under normal circumstances, a new study shows. Men tend to be attracted to women whose facial features are like their own, but if stress is added to the equation, they flip to females who don’t...

PSAs Drive Bingers to Drink More: Study

Drinkers already feel guilty; ads make them feel worse

(Newser) - The shaming quality of public-service announcements aimed at curbing binge drinking actually pushes such drinkers to imbibe more. And, a study finds, the spots are often so guilt-inducing that they can push someone feeling bad about some other malfeasance—cheating, say—to drink. One of the researchers suggests a different...

Heart Risk Linked to Obesity—in Preschoolers

Definitive connection can't be made due to lack of relevant study

(Newser) - Levels of a marker tied to adult heart disease were twice as high in the blood of obese children as in the blood of average-weight kids in a recent study. The twist is that the research subjects were 3 to 5 years old, sparking concerns about the cumulative health effects...

Half of 6-Year-Old Brit Girls Wish They Were Skinnier

In study, 50% would like to be 3 sizes skinnier for popularity

(Newser) - Half of the 6-year-old girls in Britain would like to be a lot skinnier than they are. That’s the conclusion of a Cambridge study that asked the pint-size participants to choose an ideal body from digitally altered photographs of themselves. Fifty percent went with the skinniest image, which was...

Researchers Find Cancer 'Fingerprints'

Rearranged chromosomes can be used to ID tumors, personalize treatment

(Newser) - Scientists have developed a new, more accurate method of tracking specific cancers using genetic “fingerprints”— the unique way every cancer rearranges chromosomes. Those rearrangements can be pinpointed with new genetic sequencing methods, allowing doctors to follow the cancer’s trail in the blood. The breakthrough is a key...

When Shoveling Increases, So Do Heart Attacks

Studies show exertion-related cardiac deaths surge during storms

(Newser) - Take it easy, snow shoveler—your activity causes heart attacks. Well, not exactly, Slate reports, but 2 studies show a strong correlation between heavy snowfall and an increase in heart attack deaths. In one, deaths went up 22% in the week of Northeastern blizzards and remained up in the next...

Botox Numbs Emotional Response

If you can't frown, brain finds it harder to be sad, study surmises

(Newser) - If you turn your frown upside down with Botox, your brain gets the message and makes you less receptive to negative emotional stimuli. That’s the conclusion of a new study of people who had their frown muscles paralyzed with the cosmetic toxin. Researchers tested subjects on the speed of...

Harm to amygdala seems to impair 'loss aversion'

Being Terrific Uncles Helps Gays Keep Genes Going

Nieces, nephews then more likely to keep bloodline going

(Newser) - Gay men’s tendency to lavish love and attention on their nieces and nephews could be a key to keeping a “gay gene” alive, a study shows. Looking at male homosexuals in Samoa—where they’re considered their own gender, and therefore fully integrated into family life—scientists saw...

Turns Out Abstinence Ed Does Cut Teen Sex

It beat safe sex program in recent study

(Newser) - Abstinence-only sex education is back on solid scientific ground, with a study showing the method may be more effective than safe sex education in discouraging young teens from taking the plunge. Different groups of 6th- and 7th-graders were given short courses in abstinence, safe sex, or a combination of the...

'Climategate' Scientist Faces New Fraud Claims

Data behind some work of Jones work can't be verified

Wacky Winter Seen As Sign of Climate Change

Less ice means more moisture in air and more precipitation, study says

(Newser) - The severe winter weather affecting the United States is just another symptom of climate change and global warming, says a new report. The National Wildlife Federation study surmises that the unusual volume of precipitation this year is the result of more atmospheric moisture because the Great Lakes are “less...

Mysterious drop most acute with mothers considered least at risk

(Newser) - The birth weight of the average full-term baby born in the US decreased by 1.83 ounces between 1990 and 2005. Researchers discovered the trend, which runs counter to received notions about increasing birth weight, after studying the records of 37 million newborns. Even more surprising, babies delivered by the...

Non-Stick Chemical Linked to Thyroid Issues

PFOA is used in pots and pans, furniture and even clothes

(Newser) - A common household chemical used to make non-stick pans, stain-resistant furniture, and even apparel has been linked to an increased risk of thyroid issues. The chemical, PFOA, is inert and can stay in human tissue for long periods. Researchers looked at medical records of almost 4,000 Americans and found...

Sperm Shows a New Trait: Teamwork

It works together to keep rival male's sperm out of the picture

(Newser) - The sperm’s pursuit of the egg is not the free-for-all we might think it is, but rather a test of teamwork—at least in deer mice. The female of the species tends to have multiple partners, and a new study shows that sperm from one male tend to cooperate...

Artifact from 1000 BC shakes up timetable
