Ron & Don: Penguins made ‘big mistake’ trading Ryan Reaves

  Ron & Don: Penguins made ‘big mistake’ trading Ryan Reaves The Penguins emerged as the early winners of Friday’s three-team trade that saw the two-time defending Stanley Cup champions acquire Derick Brassard as they prepare for a three-peat. But Don Cherry isn’t so sure. While all the focus has been on how Brassard will fit into the Penguins’ already-dangerous group of forwards, Cherry believes the team’s decision to move Ryan Reaves to Vegas as part of the deal will ultimately prove costly — especially for Sidney Crosby. “Everybody’s talking about Brassard, but wait a minute. Remember, this year Crosby has not missed a game due to injuries.

Numbering more than 1.5 million birds, they were first noticed “when great patches of their poo, or guano, showed up in pictures taken from space,” says the BBC.

The researchers, who detail the discovery in the journal Scientific Reports, say it is a total surprise.

“It's a classic case of finding something where no-one really looked! The Danger Islands are hard to reach, so people didn't really try that hard,” team-member Dr Tom Hart from Oxford University, UK, told the BBC.

Any Life on Proxima B May Have Been Wiped Out Last Year

  Any Life on Proxima B May Have Been Wiped Out Last Year Although the flare lasted just 10 seconds, it made the star appear about 1,000 times brighter than usual.Proxima Centauri let loose a flare that sent charged particles flying toward any planet in its orbit. Although it lasted just 10 seconds, it made the star appear about 1,000 times brighter than usual and was about 10 times brighter than the most impressive flares from our sun that scientists have studied. The paper suggests those kinds of outbursts could be common—and deadly.

The story of how scientists discovered a massive “ supercolony ” of Adélie penguins in Antarctica —which they detailed in a study published Friday (March 2) —begins in 2014, with NASA satellite imagery.

“When we first got these pixels of guano, I thought it might be a false alarm,” Heather Lynch, another team-member told The Wall Street Journal, adding, “It wasn’t. We had massive penguin colonies that had not been known to exist.”

“The sheer size of what we were looking at took our breath away. We thought, if what we're seeing is true, these are going to be some of the largest Adélie penguin colonies in the world, and it's going to be well worth our while sending in an expedition to count them properly.”

The discovery has eased fears that numbers of Adelie penguins had been in decline for decades due to climate change.

“Not only do the Danger Islands hold the largest population of Adélie penguins on the Antarctic Peninsula, they also appear to have not suffered the population declines found along the western side of Antarctic Peninsula that are associated with recent climate change,” said Professor Michael Polito, an ecologist at the Louisiana State University who participated in the research.

“It puts the East Antarctic Peninsula in stark contrast to the Adélie and chinstrap penguin declines that we are seeing on the West Antarctic Peninsula,” said Hart.

“It’s not clear what the driver of those declines is yet; the candidates are climate change, fishing and direct human disturbance, but it does show the size of the problem.”

This stark comparison “suggests penguins fare much better when their environments are completely undisturbed, a finding that reinforces calls from environmentalists for a protects area in the Weddell Sea, where the Danger Islands are located,” says BusinessInsider.

A breakthrough discovery of this scale “offers ecologists hope: Even in the age of Google Earth, maybe we don’t know our planet as well as we think we do,” says Quartz.

Scientists discover microplastics in Vancouver water samples .
A group of scientists have launched a challenge to combat plastic pollution in local waters by asking people to reduce single-use items like plastic cups and shopping bags — and be more mindful of everyday plastic use. The scientists, with the Ocean Wise program, gathered water samples from the waters just outside Canada Place 10 days ago and found 1,258 tiny particles of plastic in one cubic metre of seawater. Ocean Wise is an ocean conservation organization headquartered at the Vancouver Aquarium. 90 per cent plastic fibres "Ninety per cent of the particles we examined were fibres," said Dr.
