Just one minute of intense exercise produces significant health benefits

A single minute of very intense exercise produces health benefits similar to longer, traditional endurance training, new research indicates. The findings put to rest the common excuse for not getting in shape: there is not enough time. Read more…

Plants might remember with prions. Science News
There’s no known mad plant disease. But prions — which show their dark side in mad cow disease — may occur in plants as a form of memory. Read more…

Laundry pods more toxic than traditional detergents: study. CBC

Laundry detergent packets or ‘pods’ may be less messy and more convenient than traditional detergent. But if there’s a young child in your home, these brightly coloured, sweet-scented little capsules could also be deadly.

A U.S. study conducted by the Center for Injury Research and Policy of the Research Institute at Nationwide Children’s Hospital, in conjunction with the Central Ohio Poison Centre, found that laundry detergent packets pose more of a danger to toddlers than traditional laundry detergent or dishwasher detergent.  Read more…

Particles in air help fatten clouds’ water droplets. Science News for Students

By making their own clouds, scientists have figured out how some of the fattest water droplets form. And, they find, it’s what’s on the outside that matters.

Climate scientists need to understand how water droplets assemble into colossal clouds. That’s the only way they can reproduce cloud formation in the computer programs that they use to model climate change. Right now, that’s something that these computer models struggle with.  Read more…

A new way to get electricity from magnetism. Science Daily

‘Inverse spin Hall effect’ works in several organic semiconductors.

By showing that a phenomenon dubbed the ‘inverse spin Hall effect’ works in several organic semiconductors — including carbon-60 buckyballs — physicists changed magnetic ‘spin current’ into electric current. The efficiency of this new power conversion method isn’t yet known, but it might find use in future electronic devices including batteries, solar cells and computers.  Read more…

Carbon dioxide could explain how geysers spout. Science News for Students

Yellowstone National Park, in the western United States, holds more geysers than any place else in the world. For 150 years, scientists have blamed hot water alone for fueling those spectacular watery eruptions. But scientists have been monitoring the innards of these gurgling geysers. And it’s not the hot water alone that’s making them spurt into the air like a fountain. Carbonation helps the geysers erupt — like shaken cans of soda pop, they now report.  Read more…
