A Week of Bad Sleep Alters Your Genes

Study finds 'dramatic changes' taking place within days

(Newser) - Sleeplessness starts to bring about dramatic changes in the body within just a few days, disrupting hundreds of genes, hindering the body's ability to repair itself, and raising the risk of illnesses linked to immunity and stress, according to new research. Researchers analyzed the blood of subjects after they...

Wanted: 'Adventurous' Woman to Birth Neanderthal

Bringing Neanderthals back could save humanity, geneticist says

(Newser) - A Harvard professor has hatched a plan to bring back the Neanderthals—but he needs an "adventurous" female volunteer to deliver a knuckle-dragging bundle of joy. George Church, a geneticist who helped pioneer the Human Genome Project, says it is now possible to create artificial Neanderthal DNA from bone...

Genes Show Ancient Link Between Australia, India

Migrants from India brought dingoes, researchers say

(Newser) - The belief that Australia's Aborigines existed in isolation for tens of thousands of years before the arrival of European settlers has been upended by a new genetic study, the BBC reports. Researchers found that while there is a strong genetic link between Aboriginal Australians and the people of New...

Experts Target Lung Cancer With 'Tailor-Made' Drugs

Scientists look at DNA mutations in cancer tumors

(Newser) - Scientists are trying to help lung cancer sufferers by designing "personalized" drugs tailor-made to suit each DNA mutation of the disease, the New York Times reports. The first major study of squamous cell lung cancer—which kills more people annually than breast cancer or colon cancer—found that drugs...

We Could Soon Know Truth About Elephant Man

Genome sequencing could reveal his true ailment

(Newser) - It's been more than a century since Joseph Merrick—the so-called Elephant Man—died at age 27, but researchers still can't definitively explain the huge growths on his body. Though he was nicknamed after the parasitic infection Elephantiasis, other scientists believe he may have suffered from the congenital...

Breast Cancer: Not One but 10 Diseases

Genetic study offers 'completely new way of looking at breast cancer'

(Newser) - Breast cancer isn't a single disease but an umbrella term for 10 genetically distinct diseases, according to the biggest-ever study of the genetics of breast tumors. The researchers, who split the disease into 10 categories after examining samples from 2,000 tumors, say the study offers a "completely...

Sex With Neanderthals Boosted Our Immunity

Scientists make 'stunning' discovery in genome comparison

(Newser) - Three years ago, scientists thought humans had never had sex with Neanderthals. Last year, they changed their tune—and now it looks like DNA passed down from Neanderthals has had a “profound impact” on our immune systems. Scientists compared a section of the modern human genome to the same...

Scientists Find 'Happiness Gene'

But they warn: Don't blame everything on biology

(Newser) - If you’re generally less than jubilant—or unfailingly cheerful—your biological makeup may play a role. Scientists have tracked down a gene whose variants appear to be linked to happiness, the Guardian reports. In a study of 2,500 Americans, those who had two long variants of the gene...

Stuttering Is in the Genes

It's physical, not psychological: researcher

(Newser) - Stuttering has long been considered a psychological issue, something born of anxiety or trauma—but new research suggests it’s in the genes, the Telegraph reports. “The brain actually looks different in people who stutter compared with those that don’t,” says a scientist. Certain gene variations often...

New DNA Test Reveals Children Born of Incest

...and it does so without needing mom or dad's DNA

(Newser) - Suspect your parents may have been related? Well, now you can find out behind their back, thanks to new advances in DNA testing, USA Today reports. In a study published yesterday, doctors revealed that they can now determine if a child is born of incest without testing the DNA of...

'Drunken' Gene Found

Gene variation causes people to get drunk faster, may stave off alcoholism

(Newser) - A "drunken" gene—or, some might say, a "lightweight" gene—has been discovered by researchers probing the causes of alcoholism. Some 20% of people have a version of the gene CYP2E1 that causes them to get drunk much faster than others. The researchers say these people are less...

Lack of Sunshine Linked to MS, Arthritis

Vitamin D affects 229 disease-linked genes

(Newser) - A lack of sunshine makes people more likely to contract diseases including arthritis, multiple sclerosis, Type 1 diabetes, and some cancers, according to scientists exploring the genetic link between disease and low levels of vitamin D. Genetic researchers found that the vitamin—which the body makes when the skin is...

Scotland's Bad Weather Means More Redheads

Cloudier climes allowed trait to gain in population

(Newser) - The cooler, cloudier climes for northern Europe make for more redheads—particularly in Scotland and Ireland, a researcher says. About 8% of Scots sport a ginger mane, to less than 2% of all Europeans. The theory, Emily Pritchard tells the Times of London, is that genetic traits that allow sun-unfriendly...

Rights to Human Gene Patents Go on Trial

Do patents on breast, ovarian cancer genes, retard new research?

(Newser) - A Manhattan judge yesterday heard arguments on whether human genes should be covered by patents. A company called Myriad Genetics is being sued over its patents on two genes linked to an increased risk of breast and ovarian cancer—BRCA1 and BRCA2. The suit alleges that women's health is harmed...

Study of Obsessive Dogs Turns up OCD Gene

Study sheds light on OCD cause in both humans and dogs

(Newser) - Dogs that engage in compulsive behavior like tail-chasing and blanket sucking share a genetic variation, according to new research. The researchers believe the study of Doberman pinschers—a breed especially vulnerable to canine OCD—sheds new light on the causes of the disorder in both humans and animals, the New ...

HIV Genome Decoded, Raising Hopes for Treatment

(Newser) - The entire structure of the virus that causes AIDS has been decoded for the first time, a breakthrough that may eventually lead to effective treatments for the disease and others like it, Reuters reports. University of North Carolina researchers, using a new method they liken to zooming out on a...

Scientists Retract Paper Touting Sperm From Stem Cells

But say attribution, not science itself, at issue

(Newser) - A paper by British scientists on the creation of synthetic human sperm had to be retracted from the journal Stem Cell and Development, AFP reports. The paper, which reported the revolutionary creation of sperm from stem cells, included text written by another scientist, who was not credited. The retraction is...

New Gene May Predict Onset of Alzheimer's

Subtle Sweet Tooth May Keep Brits, French Alive

Fungus Poised to Kill Off World's Wheat

US scientists race to find plants resistant to the Ug99 fungus

(Newser) - A rust-colored fungus could destroy 80% of the world's wheat crops in a few years unless scientists counter it with genetically resistant strains, the Los Angeles Times reports.
