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... More »

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,... More »

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. More »

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... More »

Quest on for Chocolate Genome

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... More »

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,... More »

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... More »

Grapevine Genome Yields Secrets

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... More »

25 Biggest Scientific Discoveries

From the unfathomably small to the mind-blowingly huge, the most significant breakthroughs

(Newser) - The invention of the wheel was pretty good. Fire, even better. But what has science done for us lately? USA Today lists the top 25 scientific discoveries; here are the top 10:
  1. Accelerating universe
  2. Human genome
  3. Climate accord

New Genetic Ties to MS Found

Findings represent stunning medical breakthrough

(Newser) - Scientists have pinpointed two genes that may be linked to MS, signaling a breakthrough in the fight against the debilitating disease 20 years in the making. In separate studies published today by two medical journals, researchers revealed one specific gene receptor may trigger cells to inhibit the body's autoimmune reaction,... More »

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... More »

Dog Breeders Deploy DNA Tests

Genetic screening enables breeders to design dogs to suit their needs

(Newser) - With the first map of a dog genome recently completed, scientists are hot on the trail of  genes for individual canine traits from coat color to cocking their heads in a cutesy way—and dog breeders are right behind them. Without any of the inhibitions attached to eugenics in humans,... More »
