Researchers say they’ve found more DNA evidence that possibly shows gay men don’t have a choice — that their biological makeup drives them to homosexuality. In a study at Chicago University, researchers looked at DNA chains of 400-plus pairs of gay brothers and found what they said were two distinct bits of genetic material that they claim are linked to homosexuality, The Daily Mail reported. The gay brothers were identified and recruited to help with the study over the course of several years’ worth of Gay Pride festivals and marches. The research was highlighted during the recent annual American Association...

"Anybody you see around here dressed in a Tyvek suit will be someone from Greenpeace," David Stoltzfus joked as we surveyed the thousands of carefully numbered corn plants growing in the stony rust-colored soil of a former sugar cane plantation just a few miles inland from the spectacular Wailea Beach. Stoltzfus, who heads Monsanto's Piilani seed production farm on Maui, was referring to the white disposable coveralls that protesters wear for the TV cameras when "decontaminating" biotech crop fields. Hawaii is the epicenter of a furious campaign to shut down production farms that yield genetically modified seed. It was September,...

Being gay could be in the DNA. Scientists have found two stretches of DNA linked to homosexuality in men. The confirmation of the existence of a ‘gay gene’ or genes will strengthen arguments that homosexuality is a matter of biology, rather than choice. However, it also raises the prospect of a genetic test that could be used by insurance companies to discriminate against clients or by pregnant women to abort gay babies. In the study, Chicago University researchers analysed the DNA of more than 400 pairs of gay brothers, recruited at Gay Pride festivals at marches over several years. This...

An online petition to save a healthy young giraffe from death has failed, despite thousands of signatures from animal lovers. Copenhagen Zoo said it euthanized the male, named Marius, on Sunday because of a duty to avoid inbreeding. After an autopsy, "Marius" was dismembered in front of a zoo audience that included children, and fed to the zoo's lions.

**SNIP** Lippert, who had been convicted in a high-profile kidnapping in 1975, worked at the clinic part-time from 1988 to 1993, the University of Utah confirms. In his kidnapping case, reported by People magazine in 1975, Lippert abducted a 21-year-old female student at Purdue University whom he attempted to "brainwash" into falling in love with him through electric-shock therapy. The surprised mother told KUTV that she didn't know his criminal history until now. But she says she does remember him as being at the clinic when she visited, specifically in the front desk area.

The blood in Irish veins is Celtic, right? Well, not exactly. Although the history many Irish people were taught at school is the history of the Irish as a Celtic race, the truth is much more complicated, and much more interesting than that ... Research done into the DNA of Irish males has shown that the old Anthropological attempts to define 'Irish' have been misguided. As late as the 1950s researchers were busy collecting data among Irish people such as hair colour and height, in order to categorise them as a 'race' and define them as different to the British....

In a prehistoric version of "the chicken or the egg" question, researchers have long debated which animal group came first. A traditional view pegs sponges—marine creatures that look more like rocks or corals—as our ancient ancestors. But a new genetic study is stirring the waters, suggesting comb jellies, gelatinous marine animals that look similar to jellyfish, are actually the first animals to have evolved over 600 million years ago.

A shocking case of a family of ~40 in rural Australia, the “Colts” (it’s a pseudonym), which has engaged in several generations of first degree incest has surfaced. You can read the summary in the press. But the Australian government has released a report on the case. I haven’t read most of it because the snippets I have stumbled upon are very disturbing. But, I was curious as to the characterization of the 12 children who were removed by social services. In particular, only one, Cindy, had parents who were unrelated. Note how different she is: Cindy Colt (5), Rhonda...

Scientists have discovered a second code hiding within DNA. This second code contains information that changes how scientists read the instructions contained in DNA and interpret mutations to make sense of health and disease. UW scientists were stunned to discover that genomes use the genetic code to write two separate languages. One describes how proteins are made, and the other instructs the cell on how genes are controlled. One language is written on top of the other, which is why the second language remained hidden for so long. The genetic code uses a 64-letter alphabet called codons. The UW team...

The common perception of purebred dogs is that they are more striking, beautiful animals than they would be without human intervention. However, that notion has been thrown to the dogs. Strong photographic evidence has emerged that shows how 100 years of breeding has actually warped the good looks of the original hounds.

The $126 million genetic-testing company can tell you how to live smarter, better, and longer. It can also tell you what might kill you. You can purchase 14 gallons of organic milk or 396 lollipops. You can give her 33 rides on the Ferris wheel at the state fair, or you can get him a couple of violin lessons. You could put the money in a savings account, you could buy her her very own LeapFrog LeapPad Explorer digital learning tablet, or you could buy enough pizzas to feed all of her friends on the block. So many options, so...

SANTA FE—Where did the first Americans come from? Most researchers agree that Paleoamericans moved across the Bering Land Bridge from Asia sometime before 15,000 years ago, suggesting roots in East Asia. But just where the source populations arose has long been a mystery. Now comes a surprising twist, from the complete nuclear genome of a Siberian boy who died 24,000 years ago—the oldest complete genome of a modern human sequenced to date. His DNA shows close ties to those of today's Native Americans. Yet he apparently descended not from East Asians, but from people who had lived in Europe or...

A dental study of 1,200 molars and premolars from 13 hominin species shows that no known species matches the expected profile of the last common ancestor of Homo neanderthalensis and anatomically modern Homo sapiens. The study, published online in the Proceedings of the National Academy of Sciences, also provides evidence that the lines that led to Neanderthals and modern humans diverged about 1 million years ago – much earlier than previous studies have suggested.“Our results call attention to the strong discrepancies between molecular and paleontological estimates of the divergence time between Neanderthals and modern humans. These discrepancies cannot be simply...

Every cell in your body has a little clock ticking away in it. Your heart may be “younger.” Tumors are the "oldest." Embryonic stem cells, the body’s master cells, look just like newborns with a biological age of zero.

In genetics, it’s not just the living who advance the field: DNA preserved in the brittle bones of our ancestors can provide significant insight into our genetic history. Such is the case with a new genetic history of Europe, traced by an international team of researchers and published today in Science. By creating a seamless genetic map from 7,500 to 3,500 years ago in one geographic region, scientists discovered that the genetic diversity of modern day Europe can’t be explained by a single migration, as previously thought, but by multiple migrations coming from a range of areas in modern day...

The majority of Ashkenazi Jews are descended from prehistoric European women, according to study published today (October 8) in Nature Communications. While the Jewish religion began in the Near East, and the Ashkenazi Jews were believed to have origins in the early indigenous tribes of this region, new evidence from mitochondrial DNA, which is passed on exclusively from mother to child, suggests that female ancestors of most modern Ashkenazi Jews converted to Judaism in the north Mediterranean around 2,000 years ago and later in west and central Europe.

A transgender man is the first in Europe to give birth to a baby after becoming pregnant through a sperm donor. The unidentified man, who was born a woman, delivered the baby boy at home with a midwife in the poor Neukoellin district of Berlin. He insisted on a home birth because he refused to be listed as the mother on any hospital documents - a legal requirement of in Germany. The case in Germany mirrors that of Thomas Beatie in the US, pictured, who has given birth to three children and was the first man to ever give birth...

The scientists examined the DNA of mitochondria, tiny power plants within cells that get passed down from mother to child. Scientists use mitochondrial DNA from living populations to decipher ancient movements of their ancestors. Most studies have examined only a small part of the mitochondria's circular piece of DNA. But Antonio Torroni, a geneticist at the University of Pavia in Italy, and his coauthors compiled complete mitochondrial genomes from 41 native North Americans and combined that data with information from previous studies... supports the widely accepted notion of an initial coastal migration wave. A second wave of migration probably left...
