Moms Can Carry Sons' DNA in Brains for Years

New study finds first evidence of phenomenon in humans

(Newser) - For the first time, researchers have found that DNA from fetuses can migrate into a mother's brain and stay there for years, LiveScience reports. The process of mothers and fetuses exchanging cells, known as microchimerism, has been observed in the past, but until now scientists had only found evidence...

Trayvon Never Touched Gun: DNA Test

Only Zimmerman's DNA found there

(Newser) - Only George Zimmerman's DNA was found on the gun used to kill Trayvon Martin, according to test results revealed today. The findings could undermine George Zimmerman's self defense claims, the LA Times reports. Zimmerman reportedly originally told police that Martin went for the gun. The tests prove that...

'3-Parent Babies' Could Soon Be Legal in UK

Health secretary investigating risks, benefits

(Newser) - As the US continues to grapple with gay marriage, the British may be a step closer to legalizing three-parent babies. It's part of a scientific strategy to help eliminate debilitating genetic problems. The three-parent technique would involve using some healthy DNA from a third party who's not the...

Face Shape: It's All in the Genes

DNA could one day provide forensic facial sketches

(Newser) - In the future, a single shred of DNA could reveal the image of a person's face, thanks to a new discovery. For the first time ever, scientists have found genetic code associated with determining facial structure. The five genes were located by measuring nearly 10,000 people's faces...

Scientists Create 'Google Maps' for Genome

ENCODE project proves humans' genetic code has little 'junk'

(Newser) - Scientists today unveiled the most in-depth exploration yet of the human genome—complete with what they're likening to a "Google Maps" system that allows researchers to explore it. The research, which involved 1,600 experiments conducted by hundreds of scientists in dozens of labs, promises to fundamentally change...

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...

Genes From Mom Give Females Edge on Long Life

Mutations that hurt males still get passed along

(Newser) - Natural selection usually eliminates the most dangerous mutations in our DNA—but one "loophole" ends up being a raw deal for males, LiveScience notes. It involves mitochondrial DNA, which typically comes entirely from the mother. Over time, moms weed out harmful mutations instead of passing them along to offspring....

This Exists: DNA Tests for Cats

Now you can verify your cat's lineage

(Newser) - Do you have a burning desire to know your cat's ancestry? Are you dying to know if she's really a pure Abyssinian or if the guy at the pet store ripped you off? Well, now you can. Lyons Feline Genetics Laboratory at the University of California now offers...

If You Eat Poorly, Your Grandkids Pay Price

Diet can actually change your DNA: studies

(Newser) - What you eat can take a toll on your DNA, and the phenomenon can last for generations, two studies suggest. In other words, regardless of your children's and grandchildren's nutritional habits, your diet could put them at higher risk for obesity and diabetes, LiveScience reports. Researchers found that...

Signs Found of Mysterious Neanderthal 'Sister Species'

Evidence lives on in the DNA of modern-day Africans: scientists

(Newser) - Newly discovered bits of "foreign DNA" in modern Africans indicate that a mysterious "sister species" may have walked the earth with Neanderthals and humans, according to scientists. The DNA doesn't resemble DNA from any modern-day humans, nor from Neanderthals, whose DNA sometimes shows up in modern-day Europeans....

DNA Links 1987 Killing to Ex-Con

Edwin Alcaide, 53, accused in murder of young woman

(Newser) - The brutal 1987 murder of a young woman in New York City may finally be cracked. DNA found under the fingernails of Lissette Torres has been matched to Edwin Alcaide, 53, an ex-con with a violent history who was an acquaintance of Lissette's then-boyfriend, reports DNAinfo.com . Lissette was...

First Americans Arrived Via Land Bridge in 3 Waves

But those waves may have intermingled

(Newser) - The Americas weren't initially populated in one sweeping migration across the land bridge from Siberia, but in three distinct waves, according to a new DNA study. By comparing genetic markers on 52 modern day Native American populations and 17 Siberian ones, they've concluded that while the Americas were...

DNA Found at Occupy Site a Clue to 2004 Murder?

Sarah Fox's killer never found

(Newser) - Could DNA found at an Occupy Wall Street protest site help to solve a 2004 murder? In March, a chain was used to prop open a subway emergency exit door, allowing Occupiers to ride free. Police ran the DNA found on the chain in hopes of tracking down the culprit—...

New Clues Emerge on John the Baptist's Bones

Dating strengthens case that saint's bones have been found in Bulgaria

(Newser) - Scientists may have cracked the hunt for John the Baptist's bones. New radiocarbon dating is strengthening the case that the saint's bones were discovered at the site of an ancient Bulgarian church dedicated to him. Dating places the bones in the same First-Century period when John the Baptist...

If Your Dad Is Older, You May Live Longer

Older men provide life-expectancy boost in baby's DNA: study

(Newser) - As men get older, their DNA matures—and when that genetic material is passed on to children, it may mean a longer life for the kids, researchers find. Thus kids with older dads and grandfathers may be "genetically programmed" for higher life expectancies, the BBC reports. It all comes...

Islanders' Blond Hair Is Genetic Quirk

It comes from a gene mutation, not Europeans

(Newser) - A peculiar pairing of dark skin and blond hair in the native population of the Solomon Islands is due to a unique gene and not, as previously thought, the intermingling of Europeans with the inhabitants, finds a new study. About 5 to 10% of the indigenous peoples on the islands...

Police Check MI6 Agents' DNA in Dead Spy Probe

They think a coworker was in Williams' flat

(Newser) - London Metropolitan Police suspect that one of Gareth Williams' MI6 co-workers was in his apartment the night he died, and they want DNA samples from 50 of them to test that theory, the Telegraph reports. Weak traces of DNA from at least two people have been found in the flat,...
