Since fast radio bursts (FRBs) were first discovered over a decade ago, scientists have puzzled over what could be generating these intense flashes of radio waves from outside of our galaxy. In a gradual process of elimination, the field of possible explanations has narrowed as new pieces of information are gathered about FRBs - how long they last, the frequencies of the radio waves detected, and so on.

Lobby Watch: Moderna ramps up efforts regarding management of COVID-19 vaccine deliveries By Janet E Silver. Published on Apr 12, 2021 10:48am Parliament Hill pictured on Jan. 15 (Jolson Lim/iPolitics)
As the number of COVID-19 cases in Canada continues to surge, the push to vaccinate as many people as possible has intensified, but the cross-country rollout is still dealing with delays in the supply chain.
Last week Moderna was set to deliver 855,000 vaccine doses, which, as of Monday morning, had yet to arrive.
In an effort to reach out to the government to discuss the management of vaccine deliveries, the Massachusetts-based company has signed on with PAA Public Affairs Advisors, which has registered seven staffers to work on the file: Steve Van Groningen, Julie Groleau, Susan Cui, James Anderson, Felix Wong, Michael Von Herff and Noah Niznick.
