HAS IT EVER amazed you how quickly children seem to recover from injuries? Tumbles and falls are just part of everyday play. But it’s not what it’s like for adults — or grandparents for that matter. Falling or breaking a bone can be a dangerous event, because injuries are not easily healed.
Why is that?
We all know that obesity and type-2 diabetes are nearly epidemic in Canada and the United States but our ample aliments lead to an abundance of ailments.
Jacob Krich was recently hired by the University of Ottawa as a researcher of high-efficiency photovoltaics and as an assistant professor in the physics department. Krich studies the ways both organic and inorganic materials can convert light into electricity.
On Saturday, Oct. 13, just over 100 idea-seekers gathered in the Alumni Auditorium to participate in TEDxUOttawa, a conference of ideas.
“What is the point of education if the information is available to all?” – Mark Salter, professor of political science
Extremely short infrared laser pulses blast through the air, tearing electrons off their atoms and creating plasma.
“ARC says something about where the university currently is and where it is going,” said Mona Nemer, vice president of research at the U of O.
The microscopic world of E. coli and other bacteria is a mixed-up place.
How did your liver cells know to specialize into a liver or your brain cells to become neurons?
The problem CYBORGS AREN’T SCIENCE fiction. All around us people with pacemakers, insulin pumps, and prosthetic implants continue to live normal lives because of mechanical and electronic parts within their bodies. It’s not sci-fi; it’s mundane. But that doesn’t mean combining human bodies with technology is scientifically simple. Even relatively straightforward implants need to be …
The problem DO YOU EVER stop to think about your cells’ needs? Every one of the trillions of cells making up your body requires energy and is fed by blood. Armies of red blood cells continually parade through the heart, to the furthest backwaters of your body, and back again. To get to every part of …
Environmental focus for project addressing capacity issues THE NEW $112.5-million social sciences building, towering above the University of Ottawa campus, is nearing completion. Funded by federal and provincial governments and the university, the tower addresses capacity problems at the university while implementing sustainable and environmental initiatives. Capacity for social sciences The renovations to the Vanier building and the construction of the building will add …
What’s he building in there? The problem EVERY CELL THAT makes up our body carries genetic information needed to create a human being. Before birth, those cells become specialized—some cells are blood cells, some are kidney cells, some are neurons, and some are stem cells that have the freedom to become any cell the body needs. …
Survival of the same The problem NATURAL SELECTION IS one of the cornerstones of modern science. Genetic mutations cause organisms to be more or less fit to survive; those who can’t compete die, while the strong pass on their genetic strengths to a new generation. Still, genomes are complicated things. Genes can react to internal …
New study shows correlation between video games and weight gain Chaput and his collaborators invited 22 healthy, normal-weight boys between ages 15 and 19 into the lab. The night before the experiment, the boys were instructed not to eat. They …
The problem HEY, SCIENCE! WHY haven’t you built me an iPod the size of a single cell yet? I’m waiting. Currently electronics are built out of bulk materials and have inherent size limitations: A wire can only be carved so small if it’s made from an everyday chunk of copper. But imagine if electronic components …
Chemistry as art The problem UNLIKE MEDIEVAL ALCHEMISTS, who only dreamt of turning lead to gold, modern chemists are experts at reshaping matter. They can produce many molecules, but the process is often wasteful and time consuming. On the other hand, Mother Nature is much more efficient at the task, proving that chemists still have …
