Researchers find protein that makes long-term memory possible
...cient mice contained increased amounts of proBDNF, demonstrating that without tPA, the animals could not make the plasmin needed to produce mBDNF. Similarly, brains of mice deficient in plasminogen also contained increased amounts of proBDNF. Dr. Lu and his colleagues are now trying to find exactly wher...Neurosurgeons identify growth of new adult brain cells, possible treatment for epilepsy

Affecting approximately two million people worldwide, MS is a chronic, inflammato...Discovery of real-time natural gas formation offers prospect for renewable energy resource
...naerobic core samples from the PRB. In addition to demonstrating that methane production by these microbes can be stimulated by the introduction of additional nutrient compounds, or suppressed by heat sterilization or the introduction of oxygen, LUCA has shown that radio-labeled CO2 (carbon dioxide) introduced to ...Ubiquitination in real-time: A world first at the Universit de Montral
...ed by the journal, Perroy and Pontier succeeded in demonstrating that the ubiquitination process of a given protein can be monitored dynamically, in real time, on living cells. The study was made possible through the use of the BRET technique, developed previously in Professor Bouvier's laboratory. Thanks to t...Vaccination with anthrax capsule protects against experimental infection in animals

In addition, the recombinant, highly purified version of PA developed and tested by the Institute is the basis for a next generation anthrax vaccine...Carbon sink or carbon source? Aerosols play role in shifts

The study shows aerosols affect the earth's regional climate in an even more profound manner by affecting its biological and chemical exchanges of the greenhouse gases. The study examined six sites across the Un...Exploring ocean life and color on the internet

...and cones to light, there was no response, further demonstrating the lack of functioning photoreceptor cells in mice lacking AIPL1. The findings in the LCA mouse model suggest a link to a previously developed mouse model called rd (retinal degeneration). In the rd model, mutations in an enzyme called PDE6 also le...Queen's biologist awarded Canada's top science prize
