Osteoporosis in mice reversed with single injection of stem cells

Age-related osteoporosis, where the bone structure deteriorates and becomes more vulnerable to fracture, is said to affect more than 200 million people worldwide. Drugs are available to treat or delay the condition, but a cure has remained elusive. Much-needed help may now be on the way, however, with scientists discovering healthy bone structure can be restored in mice with a single injection of stem cells.Read More

Fresh approach to "organ-on-a-chip" tech adds a third dimension, may eventually replace test animals

Finding a workable alternative to animal testing is one of the most important efforts currently under way in the medical world. Not only is the method not all that effective, with numerous drugs that look promising when testing on rodents falling short during subsequent clinical trials, but it's also considered to be unethical by many people. Now, researchers at the University of Toronto have made a breakthrough, creating a new platform called AngioChip, which provides a complex, three dimensional structure on which tissue can be grown that mimics functions of the human body.Read More

New algorithm helps machines learn as quickly as humans

An artificial intelligence breakthrough from the universities of New York, Toronto and MIT is showcasing the impressive ability of artificial intelligence to learn visual concepts in a single shot and manipulate them in human-like ways. The advance could lead to smarter phones, much-improved speech recognition, and computers that better understand the world around them.Read More

New company plans to revolutionize genomic medicine with deep learning

Deep learning has already had a huge impact on computer vision and speech recognition, and it's making inroads in areas as computer-unfriendly as cooking. Now a new startup led by University of Toronto professor Brendan Frey wants to cause similar reverberations in genomic medicine. Deep Genomics plans to identify gene variants and mutations never before observed or studied and find how these link to various diseases. And through this work the company believes it can help usher in a new era of personalized medicine.Read More

European climate at mercy of retreating sea ice

An international team of scientists has found that retreating sea ice between the Atlantic and Arctic Oceans is linked to weakened air-sea heat exchange in the region. This, it warns, could result in a cooler climate in western Europe and an altered or slower Atlantic Meridional Overturning Circulation (AMOC), which would have knock-on effects for the Gulf Stream and consequently for the atmosphere.Read More

Study suggests that HUD tech may actually reduce driving safety

Cruising at speed down the highway with a heads-up display (HUD) constantly feeding data into your line of sight can make anyone feel like a jet pilot on the road; totally in control of your vehicle and primed to avert any potential danger that comes your way. However, recent studies by the University of Toronto show that the HUD multi-tasking method of vehicle piloting may well not provide the extra margin of safety that we think it does. In fact, according to the researchers, it could be downright dangerous.

Breast tissue provides clues to avoid effects of aging

Our tissue's inability to repair itself as we grow older is thought to correlate with the decline in the presence of stem cells. So it follows that if stem cell function can be preserved beyond the norm, it could have implications for the aging process and adverse effects of tissue degeneration, such as cancer. Scientists from the University of Toronto have followed this line of thinking through research on the mammary glands of genetically modified mice, finding that development of the tissue can be manipulated to avoid the effects of aging.
