Vegetarian Ancestors Affect Your Cancer Risk

Those with gene mutation could overload on fatty acids

(Newser) - You've probably never given thought to what your ancestors stuffed down their gullets. Now might be the time. In a new study in Molecular Biology and Evolution, Cornell University researchers explain that people who come from a line of mostly plant eaters likely carry a gene mutation used to... More »

Why Some Smokers Don't Get Lung Disease

They may carry genes that boost lung function: study

(Newser) - Smokers could soon benefit from new drugs that improve the function of their lungs, owing to the lucky few who smoke for years with little consequence. UK researchers scanned 50,000 smokers and non-smokers, including some who suffer from chronic obstructive pulmonary disease, and identified gene mutations that enhance lung... More »

Mystery Disease Strikes Just One Family on the Planet

Joselin, Hilary Linder determined to wipe out strange genetic ailment

(Newser) - In the late 1980s, William Linder, a healthy 40-year-old doctor, came home from a vacation fatigued and with swollen legs. By 1996, he was dead, with the cause officially listed as "unknown." The years in between were full of gruesome symptoms: Swelling squeezed some of his veins so... More »

Autism Tied to Gene Mutations for First Time

'It's a turning point,' says one scientist

(Newser) - Big autism news: A number of gene mutations linked to the disease have been uncovered for the first time, announced a number of scientists in three papers published yesterday. The sobering detail: These particular mutations are super rare, and are responsible for only a very small number of autism cases.... More »

'Zombie' DNA Can Wake Up, Cause Disease

Long-inactive gene triggers form of muscular dystrophy

(Newser) - Geneticists have found the culprit causing a common form of muscular dystrophy—zombie DNA. Sort of. They've discovered that long-inactive genes—so-called junk DNA lying dormant in the human genome for thousands of years—"can rise from the dead like zombies" and cause trouble, explains Gina Kolata in the...

Monkeys Pass Altered Traits to Offspring

Genetic breakthrough will aid disease study, but troubles some

(Newser) - Japanese scientists have produced the first genetically modified monkeys that can pass on their new traits to offspring, a research breakthrough mired in ethical quandaries. The technique is meant to be used to infect monkeys with diseases like Parkinson’s and then test treatments on them, but could eventually be... More »

Heart and Gum Disease Linked by Gene: Study

Periodontitis patients should cut out risk factors, scientists say

(Newser) - Scientists have identified a link between gum disease and heart disease, the BBC reports, finding the same genetic variation in a group of patients with heart disease and a group with severe periodontitis. “Now we know for sure that there is a strong genetic link, patients with periodontitis should...

Heart 'Time Bomb' Ticking for 60M

1 in 100 have mutant gene that increases risk sevenfold

(Newser) - Scientists have discovered a mutant gene carried by 1% of the population which almost guarantees heart disease in later life, reports the BBC. Some 60 million people have the genetic time bomb, including 4% of the total population of India. The gene increases the risk of heart disease sevenfold, according... More »
