WILMINGTON, N.C. — A Wilmington apartment complex will soon be running DNA tests on dog poop to identify owners who don't clean up after their pooches do their business. The StarNews of Wilmington reports The Reserve at Forest Hills will ask the complex's 100 dog owners to have their pets swabbed for a DNA sample. Then, if poop found in the complex matches a pet, the owner will be fined and also will have to pay for the DNA testing which can cost up to $50.

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...

What a treat for all medieval historians! More than 500 years after he was killed, the skeleton of Richard III is giving them much more reliable biographical information than they acquired over the previous half a millennium. Henry VII, his successor, and opponent at Bosworth, encouraged his court historians to produce a warped picture of Richard. Thank God, then, for the miraculous discovery of his body in a Leicester car park in 2012, and the undeniable truths it provided. Analysis of his skeleton showed the king didn’t have a hunchback exactly; he suffered from scoliosis of the spine, meaning his...

The Black Death of the 14th century may be written into the DNA of survivors' descendants, new research finds. The study reveals that Roma people (sometimes known as gypsies, although this is considered a derogatory term) and white Europeans share alterations to their genetic code that occurred after the Roma settled in Europe from northwest India 1,000 years ago. The plague of the 1300s, which killed at least 75 million people, is a likely candidate for forcing this evolutionary change. "We show that there are some immune receptors that are clearly influenced by evolution in Europe and not in northwest...

hat caused the fall of the Roman Empire? A devastating plague that struck during the reign of Emperor Justinian in 541 AD, killing a quarter of the population, seems to have landed the final blow, but the identity of the infection was a mystery. Now sequencing of DNA taken from two skeletons buried in Bavaria, Germany, in the 6th century has uncovered the complete genome of Yersinia pestis, the bacteria also blamed for the Black Death that struck Europe in 1348. The find suggests that Y. pestis may have emerged to ravage humanity several times. Hendrik Poinar at McMaster University...

Here's What Happened When Neanderthals And Ancient Humans Hooked Up 80,000 Years Ago Dina Spector Jan. 29, 2014, 1:49 PM     Neanderthal REUTERS/Nikola Solic Hyperrealistic face of a neanderthal male is displayed in a cave in the new Neanderthal Museum in the northern Croatian town of Krapina February 25, 2010 By comparing the Neanderthal genome to modern human DNA, the authors of two new studies, both published on Wednesday, show how DNA that humans have inherited from breeding with Neanderthals has shaped us. Modern humans, Neanderthals, and their sister lineage, Denisovans, descended from a common ancestor. The...

The headlines about this individual having dark skin are well founded, like the Luxembourg hunter-gatherer the sample has ancestral “non-European” copies of most of the major loci which are known to have large effect sizes (SLC24A5, which is now fixed in Europeans, SLC45A2, which is present at frequencies north of 80% in most of Europe, and KITLG, a lower frequency variant known to have a major impact on skin and hair). Additionally, this individual is related to the Ma’lta individual, just like the Swedish hunter-gatherers, but unlike the Luxembourg male (which did predate the Spanish samples by 1,000 years). Lots...

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....

Police presence is often all it takes to make voluntary experiences seem mandatory. Ricardo Nieves, one of those flagged down by Reading police officers, felt the experience was anything but voluntary, and that attempting to leave would have been greeted by a possible arrest.  The Reading city council and the mayor himself also expressed concern about the use of police officers to acquire "voluntary" blood and saliva samples. For his part, Chief Heim appears to be ready to just ride out this outrage without offering any concession towards the offended public.  But if that's what Heim had planned, Nieves just threw...

In 2012, a variety of research papers associated with the ENCODE project (Encyclopedia Of DNA Elements) described how the human genome was pervasively copied—transcribed—into an amazing array of functional RNA molecules that regulate how genes and the genome function.1 Much of the pervasive transcription is based on long non-coding RNAs (lncRNAs) that have the same control features as protein-coding genes but with other functions.2 A large group of lncRNAs stay in the cell’s nucleus, where some directly regulate how genes are expressed while others help modify chromosome structure. Some lncRNAs are exported into the cell’s cytoplasm to regulate the production...

After Osama Bin Ladin was killed, someone on our side released the name of the doctor who, with DNA tests verified that OBL was in the compound. Who did it and why?

It is one of the most unusual evolutionary ideas ever proposed: humans are amphibious apes who lost their fur, started to walk upright and developed big brains because they took to living the good life by the water’s edge. This is the aquatic ape theory and although treated with derision by some academics over the past 50 years, it is still backed by a small, but committed group of scientists. From next Wednesday through Friday, they will hold a major London conference when several speakers, including British naturalist and broadcaster, David Attenborough, will voice support for the theory. “Humans are...

Drivers in a southeastern Pennsylvania town were forced off a local street and into a parking lot, so a federal contractor – aided by local police --could quiz them about their road habits and ask for a cheek swab, in a replay of an incident last month in Texas. The checkpoint, in downtown Reading, was one of several conducted by the Pacific Institute for Research and Evaluation, which was hired by the National Highway Traffic Safety Administration and the White House Office of National Drug Control Policy. Although the questioning and cheek swab were voluntary, local residents said they were...

A private firm with a federal contract - and backed up by city police - forced motorists off Laurel Street and into a private parking lot Friday to question them about their driving habits and ask for a swab of their mouth. "I feel this incident is a gross abuse of power on many levels," Reading resident Ricardo Nieves, one of those stopped, told City Council Monday. He said federal and local tax dollars were being used to stop innocent people without probable cause, and allow a private company to hire uniformed police to force citizens to listen to their...

U.S. geneticists say a second code hiding within DNA changes how scientists read its instructions and interpret mutations to make sense of health and disease. Since the genetic code was deciphered in the 1960s, scientists have assumed it was used exclusively to write information about proteins, but University of Washington scientists say they've discovered genomes use the genetic code to write two separate "languages." One, long understood, describes how proteins are made, while 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...

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...

Scientists have found the oldest DNA evidence yet of humans’ biological history. But instead of neatly clarifying human evolution, the finding is adding new mysteries. In a paper in the journal Nature, scientists reported Wednesday that they had retrieved ancient human DNA from a fossil dating back about 400,000 years, shattering the previous record of 100,000 years. The fossil, a thigh bone found in Spain, had previously seemed to many experts to belong to a forerunner of Neanderthals. But its DNA tells a very different story. It most closely resembles DNA from an enigmatic lineage of humans known as Denisovans....

Full Title is "Holiday Celebration: Robot Turtles, Poop-Snooping DNA Detectives" “Robot Turtle Will Help Underwater Archeologists Inspect Shipwrecks,” for example, has some obviously worthwhile things to point out about the development of autonomous unmanned underwater vehicles to explore dangerous environments more cheaply and safely than humans can manage. The saving grace for this report from The Robot Safari in the London Science Museum, however, is the effort the announcement goes to – and trouble the designers obviously did as well – to not only build an autonomous underwater vehicle that swims like a turtle, but justify having done so (paddle-like...

The A3/02 strain combines the two most common HIV strains in Guinea-Bissau and develops into AIDS within five years, up to two-and-a-half years faster than either of its parent strains, said Angelica Palm, one of the scientists behind the study published in the Journal of Infectious Diseases. This type of strain, a recombinant, appears when a person becomes infected by two different strains, allowing DNA to fuse and create a new one.

CAMBRIDGE, Mass., Nov. 28 (UPI) -- Humans lived for thousands of years in small, isolated populations and resulting inbreeding shaped the course of human evolution, a U.S. researcher says. Research suggests the severe inbreeding may have created many health problems and the small populations were likely a barrier to the development of complex culture and technologies, NewScientist.com reported Thursday. David Reich of Harvard Medical School in Boston -- who has sequenced the genome of Neanderthals and that of another extinct human, the Denisovans -- said both species were severely inbred due to small populations. "Archaic populations had low genetic diversity,...
