On July 5, 2017, NASA’s Solar Dynamics Observatory watched an active region — an area of intense and complex magnetic fields — rotate into view on the Sun. The satellite continued to track the region as it grew and eventually rotated across the Sun and out of view on July 17. 

A Canadian-led investigation involving York researchers has opened a new chapter in antimatter research.

In a study published in Nature today (Aug. 3), the ALPHA Collaboration – a group of international physicists including physics Professor Scott Menary in the Faculty of Science at York University – reported the first detailed observation of spectral lines from an antimatter atom.

Writing in the journal Animals, they muse on whether organisations that profit in some way from wildlife imagery and popularity, could establish a corporate responsibility to contribute a portion of this income to the conservation of the animals represented.

University of Lethbridge biogeography professor Dr. Dan Johnson and his team have been monitoring Prairie potato fields for the past few years, looking for evidence of the potato psyllid insect and a bacterium it can carry that can lead to zebra chip disease in potato crops.

“We found hundreds of potato psyllids last year, but we have found under 10 so far this year and none have the bacteria that cause zebra chip,” says Johnson, who coordinates the Canadian Potato Psyllid and Zebra Chip Monitoring Network.

Since then, many have wondered, is that even scientifically possible? Unfortunately, the odds aren’t looking good.
