[ Watch the Video ] Using observations from NASA's Rossi X-ray Timing Explorer (RXTE) satellite and the National Science Foundation's (NSF) Very Long Baseline Array (VLBA) radio telescope, an international team of astronomers has identified the moment when a black hole in our galaxy launched super-fast knots of gas into space. Racing outward at about one-quarter the speed of light, these "bullets" of ionized gas are thought to arise from a region located just outside the black hole's...

'Own the Podium' program's benefits vastly outweighed its operating costs At the Vancouver 2010 Winter Olympic Games, when Canadians roared with delight at a medal haul that placed the country at an "all-time, all-nation Winter Olympics record of 14 gold medals," athletes did more than win gold—they fired up exuberant displays of national pride and unity across the country. And new research involving the University of Alberta suggests Canadians are willing to pay to get them....

Acupuncture Safe For Kids: Study
2011-11-22 06:36:11

Acupuncture can be a generally safe treatment for children when performed by trained professionals, according to a new Canadian study published Monday in the journal Pediatrics. The researchers reviewed 37 studies or case reports, and found that in 1,422 children treated with acupuncture, just 168, or 12 percent, experienced a mild adverse reaction such as pain, bruising or numbness. The scientists identified 25 reports of serious adverse events, such as infections and other...

Dinosaur Attracted Mates Much Like A Peacock
2011-11-07 13:46:40

A new study says that a species of dinosaur may have acted like a Las Vegas showgirl in order to attract males. Oviraptor dinosaurs had a fan of feathers similar to a flamenco dancer in Las Vegas, along with a flexible tail. The scientists said this dinosaur species may have flashed these feathers to attract attention in a way similar to the modern-day peacock. Scott Persons, a doctoral student at the University of Alberta, presented the research at the Society for Vertebrate...

People Consume More Candies When Individually Wrapped

If you believe that good things always come in small packages, University of Alberta researcher Jennifer Argo's new study may change your mind -- especially this close to Halloween. In an article forthcoming in the Journal of Marketing, Argo explores how our consumption behaviors change when it comes to treats like chocolates and candies are placed in smaller packages. She says that people eat more of a product when it is placed in small packages rather that a regular-sized packages....

Large Tail Muscle Made Carnivorous Dinosaur Faster
2011-10-16 04:37:27

A massive tail muscle made a 23-foot-long carnivorous dinosaur one of the fastest-running (and deadliest) hunters of its era, a University of Alberta researcher has discovered. According to UPI reports on Friday, Scott Persons, a graduate student in paleontology at the university, used 3D computer models of re-create the tail muscles of the twin-horned Carnotaurus. Persons discovered that the dinosaur's tail had "a series of tall rib-like bones that interlocked with the next pair in...

Researchers Rebuild The Head Of An Armored Dinosaur

[ Video 1 ]  |  [ Video 2 ] A University of Alberta-led research team has taken a rare look inside the skull of a dinosaur and come away with unprecedented details on the brain and nasal passages of the 72 million year old animal. Lead researcher Tetsuto Miyashita, a U of A master's student in paleontology, examined the armored skull of a Euoplocephalus, a six-meter long plant eater. The skull, which had been sitting in the U of A's paleontology collection, was broken,...

University of Alberta researchers have identified a key regulator that controls the speed of development in the fruit fly. When the researchers blocked the function of this regulator, animals sped up their rate of development and reached maturity much faster than normal. The U of A research team, led by molecular geneticist Kirst King-Jones, noticed a peculiar behaviour of the protein they were studying, DHR4: The protein acted as a sentinel to either allow or prohibit the production of...

University of Alberta chemistry researchers have discovered an active catalyst that has the potential to improve the efficiency and environmental impact of manufacturing processes used to make products such as agrochemicals and pharmaceuticals. The research led by U of A chemistry professor Steven Bergens targeted the organic compounds known as amides, which are raw materials used by many industries to make a variety of chemical products. Bergens and his research team found that combining...
