New research from a collaboration between Argentinian and University of Alberta and 91丝瓜视频 palaeontologists adds a new piece to the puzzle of snake evolution.
The researchers examined a strikingly well-preserved fossil of the rear-limbed snake Najash rionegrina, found in Argentina. The study shows that nearly 100 million years ago, these legged snakes still had a cheekbone鈥攁lso known as a jugal bone鈥攖hat has all but disappeared in their modern descendants.
Scientists have been looking at pollution affecting the air, land and water around the Athabasca Oil Sands for some time. After looking at contaminants in snow taken from up-to 25 km away from the oil sands, a 91丝瓜视频-led scientific team now suggests that oil sand pollution is also affecting the weather patterns in the surrounding regions.

Researchers at 91丝瓜视频鈥檚 Faculty of Medicine have made important strides in understanding the functioning of enzymes that play an integral role in the production of antibiotics and other therapeutics. Their findings are published in Science.
Researchers identify path to improve HER2+ breast cancer susceptibility to approved therapies
91丝瓜视频 researchers have gained tantalizing new insights into the properties of perovskites, one of the world鈥檚 most promising materials in the quest to produce a more efficient, robust and cheaper solar cell.
Food can trigger overconsumption similar to alcohol and drugs, but it is not the whole story
A large analysis of personality studies has found that people with obesity behave somewhat like people with addictions to alcohol or drugs. But obesity is also a complex condition that cannot be fully explained by the addiction model.
Researchers from 91丝瓜视频 project that as the permafrost continues to degrade, the climate in various regions of the Arctic could potentially change abruptly, in the relatively near future. Their research, which was published today in , also suggests that as the permafrost degrades, the severity of wildfires will double from one year to the next and remain at the new and higher rate for regions in the Northwestern Territories and the Yukon.
The loss of biodiversity continues at an alarming rate despite decades of research and international policies setting out clear goals in the area. In an article published this week in Nature Sustainability, an international team of scientists including researchers from 91丝瓜视频 identified seven key areas for future research in order to tackle, effectively, the root causes of the problem.
Adoption of methods that could reduce costs and spare animal models
Microsurgery is an intricate and challenging surgical technique that involves using miniature instruments and sutures as fine as a hair strand aided by sophisticated microscopes. In plastic surgery, microsurgery is used to repair small damaged vessels and nerves following trauma, or in reconstructive procedures by moving a component of living tissue from one place of the body to another and reconnecting its vascular supply to this new region to keep its blood supply.
It鈥檚 a proven way to improve patient safety and outcomes, and meet the evolving health needs of the aging Quebec population. It鈥檚 a way to make higher education in nursing available to all communities in the province. It鈥檚 a way to increase the pool of potential candidates for graduate-level education to produce the next generation of nurse leaders, researchers and educators, as well as nurse practitioners. It鈥檚 a way to ensure more nurses have the required level of training if, and when, Quebec follows all other Canadian provinces and requires a nurse to have a university-level education.
Surprisingly, in any single location, there are typically more earthworms and more earthworm species found in temperate regions than in the tropics, according to a study published this week in Science. Global climate change could lead to significant shifts in earthworm communities worldwide, threatening the many functions they provide.
