Glow-in-the-dark stickers, weird deep-sea fish, LED lightbulbs—all have forms of luminescence. In other words, instead of just reflecting light, they make their own.
Now a team of scientists from the University of Vermont and Dartmouth College have discovered a new way that some molecules can make a luminescent glow—a strange, bright green.
“It’s a new method to create light,” says Matthew Liptak, a chemist at UVM who co-led the new research. The new light may have many promising applications including novel kinds of LED bulbs and medical dyes “that can sense viscosity within a cell,” he says.
The discovery was reported September 26 in the journal Nature Chemistry.
Cabinet ministers are headed to Canada’s west coast for an expected announcement on Petroliam Nasional Bhd’s C$36 billion ($27 billion) liquefied natural gas project, according to stakeholders who now say they expect it to be approved.
Start your day with what’s moving markets. Environment Minister Catherine McKenna, Natural Resources Minister Jim Carr and Fisheries Minister Dominic Leblanc departed Ottawa for British Columbia after a cabinet meeting Tuesday morning, an indigenous chief who opposes the development said. Another chief said he expects the announcement Tuesday afternoon. Officials in all three ministers’ offices declined to comment on the matter, but people familiar with the file said it was discussed at the meeting.
The proposed Pacific NorthWest development would be Prime Minister Justin Trudeau’s first decision on a major energy project after a pro-environment campaign swept him to power last year.
What the ministers will announce hasn’t been confirmed. The government has an Oct. 2 deadline for a final ruling. One indigenous leader, who was supposed to meet with Leblanc in Ottawa on the project, said his meeting was canceled Tuesday.
“We believe they’ll go to the next step and they’ll approve it,” John Ridsdale, a hereditary leader with the Wet’suwet’en known as Chief Na’Moks, said by phone. His community is upstream of the proposed site and he opposes its development. “We will state our adamant opposition to this. The next step for us is litigation.”
