DNA Tests Can Improve Health—and Ruin Privacy

Testing labs can sell genomes to Big Pharma

(Newser) - Genetic testing is quickly becoming cheaper and widely available, prompting questions of whether the privacy of this most personal data can be ensured, writes Peter Dizikes for Salon. Companies such as 23andMe and Navigenics can study your genes for $399 or so to determine if you're at risk for a...

Scientists Decode Neanderthal Genome

(Newser) - Scientists using ancient fossils have pieced together a rough draft of Neanderthals' genetic code, the Times of London reports. The development could eventually shed light on how they thought, spoke, and functioned, and why they disappeared. Because Neanderthals are humans' closest relatives, scientists may be able to get a better...

Scientists Map Common Cold's Genome

Makes creating a cure possible, but still pricey and unlikely

(Newser) - Researchers have completed a “family tree” for the common cold, paving the way for an eventual cure to one of mankind’s most stubborn ailments, the New York Times reports. Scientists mapped the genomes of the 99 variations of rhinovirus, which causes most colds, and have cataloged the weaknesses...

The 5 Best Species to Resurrect

DNA samples still exist for many extinct megafauna

(Newser) - Now that scientists have the woolly mammoth’s genome, the possibility of resurrecting the giant creatures—and other impressive species from our planet’s past—is a bit closer. Which megafauna would you bring back? New Scientist lists its favorites:
  • Sabre-toothed tiger. This massive cat with huge fangs would surely

Scientists Map DNA of Woolly Mammoth

Neanderthals, early humans could be next

(Newser) - Scientists have pieced together the nearly complete genome of the woolly mammoth from a hair strand found in Siberia, National Geographic reports. It's the first time scientists have decoded the nuclear DNA of an extinct species. The development makes it theoretically possible for the mammoths to roam the earth again...

Our Not-So-Distant Relatives: Kangaroos

Scientists decode marsupial's genome, find much in common with humans

(Newser) - The kangaroo genome has much in common with that of humans, the Telegraph reports. Scientists in Australia, under the auspices of the Centre of Excellence for Kangaroo Genomics, have completed mapping the marsupial’s genetic code. “There are a few differences, we have a few more of this, a...

Cancer Genes Decoded For First Time

Breakthrough view into cancer's genetic roots promises new battle realm

(Newser) - Scientists have unlocked cancer's genetic blueprint for the first time, the New York Times reports. Working with cells from a woman who died of leukemia, they decoded her entire DNA sequence and zeroed in on ten mutations that occurred only in the cancerous cells. Researchers say the breakthrough could someday...

10 Volunteers Go Public With Their DNA

Database will divulge what really makes a Harvard man, and other genetic secrets

(Newser) - Ten volunteers, including some rather well known ones, are exposing themselves online, the New York Times reports, by making their DNA available for anyone to peruse. The goal of the Personal Genome Project is to start making genetic information—along with personal traits called phenotypes—publicly available, a move whose...

100M-Year-Old DNA Regions Baffle Experts

Mice, humans share mysterious code immune to evolution

(Newser) - Certain regions of mammalian DNA with no discernible purpose have one perplexing characteristic in common: They have survived, without mutation, for as long as 100 million years, LiveScience reports. Scientists speculate that the areas have some deep purpose, but for now they know only that they are “ultraconserved regions,...

HIV/AIDS May Be 100 Years Old

Evidence of old strain discovered in Congo

(Newser) - The HIV/AIDS epidemic exploded in the 1980s, but new research shows HIV was plaguing the human population in Africa for a century before that. Old collections of human tissue samples from the Congo have produced evidence of old strains of HIV that may have emerged in 1908, reports Nature.

Missing DNA Sheds Light on Roots of Schizophrenia

Scientists disocover 3 genetic hot spots

(Newser) - Missing chunks of DNA increase a child's chance of developing schizophrenia by up to 10 times, say to two major international studies. Scientists are calling the data from more than 3,000 schizophrenia patients a huge step toward finding the genetic source of the disease, which could ultimately help doctors...

Mars aims to unlock genetic code to develop hardier cacao trees

(Newser) - Candy giant Mars is investing $10 million in a 5-year research project to unlock the secrets of chocolate's genetic code—the cocoa genome—as the first stage in developing cacao trees that can produce more, survive droughts, and combat disease. Mars intends to make the results public to stop key...

Genes ID Best Patients for Colon Cancer Drug

Step toward 'holy grail' of personalized cancer battle

(Newser) - Researchers have taken a giant step toward the "holy grail" of personalized cancer treatment—by using genetic profiling to accurately target chemotherapy, Reuters reports. A new genetic test of colon cancer tumors is able to predict with accuracy whether a patient will respond to treatment with the drug Erbitux,...

Here's Why Platypus Look So Goofy

Scientist decode its DNA, see part mammal, part reptile

(Newser) - Scientists have decoded the genome of the duck-billed platypus, National Geographic reports, with their findings as interesting as they expected. Research, published in Nature, confirms that the platypus is the earliest living offshoot of mammalian evolution, yet retains many genetic throwbacks to reptilian ancestors thought to have lived 300 million...

Cat Out of the Bag: Kitty's DNA Decoded

Deciphering feline genome could help with HIV, blindness research

(Newser) - A 4-year-old Abyssinian cat named Cinnamon has become the first of her species to have its DNA sequenced, the BBC reports. Cats now join dogs, chimps, rats, mice, cows and people as mammals with decoded genomes. Cinnamon’s sequence could shed light on hundreds of human illnesses; cats can suffer...

Discovery reveals what makes wine taste good and why it's good for you

(Newser) - Grapevines have extra genes that are responsible for making wine taste and smell so good, a new study finds. A team of researchers from France and Italy (where else?) mapped a pinot noir-related grapevine's genome and found it has twice as many genes linked to resin and oil—which give...

Early Immunity to Chimp Virus Leaves Humans Open to HIV

An advantage 4M years ago is a weakness now

(Newser) - Humans are more susceptible to HIV than other primates because our ancestors evolved a protein that could fight off a different retrovirus that infected chimps, says Scientific American. The most conspicuous difference between the chimpanzee genome sequenced in 2005 and the human one, says a Seattle virologist, was 130 copies...
