Neandertals' ...are traditionally considered carnivores and hunters of large mammals, but this hypothesis has recently been challenged by numerous pieces of evidence of plant consumption. Ancient diets are often reconstructed using nitrogen isotope ratios, a tracer of the trophic level, the position an organism occupies in a food chain. Neandertals are apparently occupying a high position in terrestrial food chains, exhibiting slightly higher ratios than carnivores (like hyenas, wolves or foxes) found at the same sites. It has been suggested that these slightly higher values were due to the consumption of mammoth or putrid meat. And we also know some...

Guinness dates back 256 years and is laden with deep cultural connotations for both the Irish and Irish diaspora here in the United States. Any significant change to it is risky.Even if it means removing an element deemed repugnant by a large segment of the population.We could be talking about isinglass — the clear collagen extracted from fish bladders that is used to draw spent yeast out of beer and clarify the finished product — but Guinness is planning to remove that particular substance from its brewing process in 2016 in favor of another less-fishy filtration method. There wasn’t all...

Originally published:  May 4 2015 - 11:45am By:  Lisa Marie Potter, Contributor (Inside Science) -- Skin has to be flexible enough to jump, crawl, and kick with us. It also has to be resilient enough to withstand our falls, scrapes, and cuts. Scientists have marveled at skin's strength for years without knowing why it's so durable.Now, scientists have identified the mechanical properties that give skin...

(Reuters) - Scientists excavating an ancient Wyoming sinkhole containing a rare trove of fossils of Ice Age mammals have unearthed hundreds of bones of such prehistoric animals as American cheetahs, a paleontologist said on Friday. The two-week dig by an international team of researchers led by Des Moines University paleontologist Julie Meachen marked the first exploration of Natural Trap Cave at the base of the Bighorn Mountains in north-central Wyoming since its initial discovery in the 1970s. Meachen said the extensive excavation that began late last month uncovered roughly 200 large bones of animals like horses that roamed North America...

A collagen-binding peptide with applications in wound healing has been developed by scientists in the US. The peptide is able to invade the strands of collagen, forming a strong and stable non-covalent bond at room temperature. Pendant drug molecules could be attached to the peptide and anchored at the wound site to aid wound healing. Representation of a collagen mimetic peptide (CMP) annealing to damaged collagen to anchor a molecule (X) in a wound bed Collagen is the most abundant protein in the body and makes up three quarters of the dry weight of skin. It is formed from three...

Close window Published online: 12 April 2007; | doi:10.1038/news070409-11 Dinosaur protein sequencedLucky find shows up record-breaking fossil.Heidi Ledford Digging through the rock in Montana yielded the surprise find. Science Palaeontologists have sequenced some protein from a 68-million-year-old fossilized Tyrannosaurus rex bone. The protein — a key component of bone and connective tissue called collagen — blasts the record for the oldest protein ever sequenced. Before this, the oldest sequenced protein (also collagen) came from a mammoth fossil that was 100,000-300,000 years old. So the new find, reported this week in the journal Science1, is quite a surprise. Scientists hope...

Volume 37, Issue 2, Page 46 doi:10.1016/S0300-7073(07)70107-X CHICAGO — Injection of adult autologous stem cells shows an excellent success rate for the treatment of urinary stress incontinence, compared with collagen injections, Dr. Matthias Schurich said at the annual meeting of the Radiological Society of North America. In the study of both women and men, 50 (79%) of the 63 patients randomized to transurethral ultrasound-guided injection of adult stem cells were completely continent after follow-up lasting 6–30 months, compared with only 2 (7%) of the 28 patients treated with endoscopic injection of collagen after 6–12 months, he reported on behalf of...

Skin from prisoners executed in China is being used to develop cosmetic collagen treatments aimed at the European market, according to The Guardian. The newspaper says that agents from a China-based company claim the skin, which is taken from prisoners after they have been shot, is being used to develop the collagen for anti-aging treatments such as wrinkle and lip-filling injections.

US star visits Sudan 28/10/2004 11:00 - (SA) Khartoum - Hollywood actress Angelina Jolie said on Wednesday the situation in Darfur was "unbelievably horrible" and that security remained a major problem, after a tour of Sudan's war-torn region. "It is just the worst thing I have ever seen ... What is happening to the people and women there is just unbelievably horrible," the United Nations goodwill ambassador told reporters in the Sudanese capital. The United Nations says the 20-month-old conflict pitting government forces and Arab militia allies against ethnic minority rebels has created the world's worst ongoing humanitarian crisis, while...

Papers have been flapping with new headlines about the latest in a long line of alleged dinosaur ancestors of birds. This one is claimed to be a sensational dinosaur with feathers on its hind legs, thus four ‘wings’.1 This was named Microraptor gui—the name is derived from words meaning ‘little plunderer of Gu’ after the paleontologist Gu Zhiwei. Like so many of the alleged feathered dinosaurs, it comes from Liaoning province of northeastern China. It was about 3 feet (1 meter) long from its head to the tip of its long tail, but its body was only about the size...
