Giant tortoise, huge carnivorous plant among Top 10 new species of 2016. CBC

A giant tortoise and a large carnivorous plant are among the Top 10 new species of 2016, along with other recently discovered plants and animals such as a red seadragon fish with pink stripes and a very tiny beetle.

The list was released by the International Institute for Species Exploration this week. It was chosen by a panel of scientists from about 18,000 species named during the previous year in order to draw attention to new species being discovered as others go extinct.  Read more…

Is aging inevitable? Not necessarily for sea urchins. Science Daily

Scientists are studying the regenerative capacity of sea urchins in hopes that a deeper understanding of the process of regeneration, which governs the regeneration of aging tissues as well as lost or damaged body parts, will lead to a deeper understanding of the aging process in humans, with whom sea urchins share a close genetic relationship.  Read more…

Dinosaur discoveries mark Jurassic Park generation’s coming of age. Globe and Mail

When paleontologist Jordan Mallon of the Canadian Museum of Nature in Ottawa was preparing to unveil a new species of horned dinosaur last week, the museum commissioned an evocative and biologically accurate illustration to go with the find.

But Dr. Mallon also asked his friend, comic book illustrator Brett Booth, to do an alternative take on the creature that has a distinctly muscular and superhero-like quality to it.  Read more…

Alberta’s oilsands industry is a huge source of harmful air pollution, study says.  CBC

Alberta’s oilsands industry is one of the biggest sources in North America of harmful air pollutants called secondary organic aerosols (SOAs), a new Environment Canada study has found.

SOAs are formed when volatile organic compounds (VOCs) emitted directly by the oilsands are exposed to sunlight and react with oxygen and other compounds in the atmosphere. VOCs emitted by cars, other industrial processes, and plants can also generate SOAs.  Read more…

Dubai opens world’s first functioning 3-D-printed office. Globe and Mail

Dubai has opened what it said was the world’s first functioning 3-D-printed office building, part of a drive by the Gulf’s main tourism and business hub to develop technology that cuts costs and saves time.

The printers – used industrially and also on a smaller scale to make digitally designed, three-dimensional objects from plastic – have not been used much for building.  Read more…

Fort McMurray wildfire ash reaches all the way to Spain. CBC

Ash and soot from the Fort McMurray wildfire has drifted all the way to Europe and could speed the melting of Greenland’s ice sheet, says a fire ecologist.

NASA satellite images, captured earlier this week, show blue streaks — representing dust and soot in the atmosphere — swirling over Spain and the U.K.  Read more…
