New York - Scientists have come up with a computer model indicating where a dust sample came from within the U.S. This is based on the DNA of fungi found in the sample.

Skeleton in Italy contains oldest Neanderthal DNA ever discovered

Altamura - A cave in Italy has given up one particularly fascinating gift: A skeleton containing the oldest Neanderthal DNA ever discovered. Scientists studying the ancient skeleton have dated the molecules found within to about 130,000 to 170,000 years ago.

Op-Ed: Ever wonder why you're afraid of spiders? Evolution provides clue

San Jos - When you live in the tropics, the neighbors tend to invite themselves into your house. In my case, sometimes it's a two-toed sloth. Other times it's a beautiful morpho butterfly. And other times it's a large, hairy spider.

Icelandic population genetically mapped

Reykjav - Scientists have performed whole-genome sequencing on roughly 1 percent of the Icelandic population. This is one of the largest studies ever performed of a distinct nation.

Scientists solve the puzzle of 'Darwin's strangest animals'

When Charles Darwin sailed the HMS Beagle to South America in the 1830's, he discovered fossils of bizarre mammals that defied classification and scientists have never been able to figure out where these creatures fit in the mammalian family tree.

DNA study: Why the Welsh might be the first true Brits

The English aren't English and the real Britons are the Welsh, says a fascinating new study into the DNA of different ethnic groups in Britain.

DNA and 'wheel' trace cultural beginnings of European language

Linguists follow the root for "wheel" while geneticists follow DNA samples of Europeans and steppe dwellers. Both conclude European language has its beginning with the Yamnaya living 6,000 years ago on the steppe north of the Black Sea.

Mothers pass traits to offspring via bacterial DNA

A remarkable study suggests that the DNA of bacteria that live in the body can pass a trait to offspring in a way similar to the parents' own DNA. This is based on studies conducted using mice.

DNA preserved in glass could store data for over 2 million years

A hard drive that stores data on a strand of DNA preserved in glass could keep data in a readable state for over 2 million years if kept in an optimal enivronment, a new report indicates.

Studying the human genome for mortality

Edinburgh - A new study has discovered a link between patterns of methylation in the human genome and people’s life span. If such technology is possible, would you want to know?

More states sending DNA samples to CODIS for misdemeanor charges

The state of Virginia considers joining a growing number of states to pass laws that require DNA samples from criminals convicted of misdemeanors.
