Magnetic nanoparticles open blood-brain barrier for delivery of therapeutic molecules

By - March 26, 2015 1 Picture
The blood-brain barrier is a highly selective semipermeable barrier running inside almost all vessels in the brain that lets through water, some gases and a few other select molecules, while preventing potentially toxic elements in the blood from entering the brain. Researchers from the University of Montreal, Polytechnique Montréal, and CHU Sainte-Justine say that currently 98 percent of therapeutic molecules are also blocked by the barrier, but they have developed a technique using magnetic nanoparticles that opens the door for such molecules, thereby also opening the door to new treatments for brain diseases.

Giant exoplanet imaged directly using infrared light

By - May 26, 2014 2 Pictures
Using an infrared camera, astronomers at the University of Montreal have discovered and directly imaged GU Psc b, a planet with a mass 10 times greater than Jupiter's and orbiting its star at 2,000 times the distance between Earth and our sun. This very rare find will encourage scientists to start looking for exoplanets in places where, thus far, they hadn't even thought to look. Read More

DNA clamps could stop cancer in its tracks

By - January 17, 2014 1 Picture
Scientists have developed a special DNA clamp to act as a diagnostic nano machine. It's capable of detecting genetic mutations responsible for causing cancers, hemophilia, sickle cell anemia and other diseases, more efficiently than existing techniques. Not only can the clamp be used to develop more advanced screening tests, but it could also help create more efficient DNA-based nano machines for targeted drug delivery. Read More

First rogue planet discovered

By - November 14, 2012 2 Pictures
While the Kepler spacecraft’s mission to discover Earth-like planets orbiting other stars continues to produce results, astronomers have found what is likely to be a planet that is not gravitationally bound to any star. The rogue planet, called CFBDSIR2149, is around 100 light years from our solar system, making it the closest free-floating planetary mass yet discovered. Its relative proximity, coupled with the lack of a bright star in its vicinity, has allowed researchers to study its atmosphere in great detail, which should help provide a better understanding of exoplanets that do orbit stars.

Pluripotent stem cells generated from horses

By - February 28, 2011 2 Pictures
For the first time ever, scientists from the University of Montreal and Mount Sinai Hospital have generated pluripotent stem cells from horses. Pluripotency refers to a cell's ability to become any of the various other types of cells found within the body, and the ability to be able to grow such cells in a laboratory setting has great implications for the field of regenerative medicine. Not only does this latest accomplishment potentially mean big things for sick or injured horses, but it could also pave the way for lab-based human stem cell treatments. Read More
