Wow. Someone’s snotty.

That was a reprint of this New Scientist piece.

They explain what suspended animation is how this procedure is different from therapeutic hypothermia.

“Unlike hibernation or therapeutic hypothermia, suspended animation is basically clinical death, without heart or brain activity.”

Thousands of 'penis-fish' are washed onto a California beach after storm pulled them from their underwater burrows
Biologist found thousands of fat innkeeper worms on the shore of Drakes Beach in California
He suggests a recent storm pulled them out of their homes made of sand and carried them to the shore
The marine creatures live in U-shaped burrows that it eventually leaves with other animals
It lives to be about 25 years old and feeds on plankton, bacteria and other small particles on the ocean
Thousands of 'penis-fish' have washed ashore Drakes Beach, California.

Formally known as fat innkeeper worm, an expert believes a recent storm forced the worms out of their underwater homes and carried them to the beach -leaving them exposed to predators.

This 10-inch marine creature looks like a 'pink sausage' and creates U-shaped burrows in mud or sand that it leaves behind for other creatures to move in - hence its name 'innkeeper'.

The sea of these 'penis-fish' was spotted by biologists Ivan Parr on December 6 after a storm hit the area.
'I've heard my share of imaginative theories from beachcombers, such as flotsam of a wrecked bratwurst freighter.'

'In truth, these are living denizens of our beaches rudely, yet also mercifully, mostly called 'fat innkeeper worms.'

I always thought that Lego was pretty cool, but I never knew just how cool it could be.

Canadian scientists want to plant a billion new trees by 2028 using a network of drones that shoot out seed pods that grow 'flash forests'

A group of scientists in Canada have announced a new initiative to use drones to plant new trees cheaply and quickly in part of an effort to fight against the negative effects of climate change and deforestation.
Called Flash Forest, the team began testing its drone delivery systems in August, with a test flight that saw them successfully plant 100 trees with a drone.
Those results were so encouraging they’ve expanded their goals to use their specially designed drone systems to plant a billion new trees by 2028.
'Every year the planet loses 13 billion trees and regains less than half of that,’ the team’s Bryce Jones said in a fundraising video announcing the project.
‘We started Flash Forest with the goal of healing the planet’s lungs and taking that job seriously. Until that job is done well, no other job matters.’
The drones don’t just carry seeds themselves, but pods of nutrient rich soil packed around three pre-germinated seeds like a casing, according to New Atlas.
The nutrient-rich padding can keep the germinated seeds alive for up to nine months, giving them plenty of time to take root in the local environment.
Each drone will be capable of shooting around one pod per second into the ground and the system will allow one human pilot to operate as many as ten drones simultaneously.
The group says their drone system can plant trees ten times faster than what a human worker could do by hand, and for one-fifth the cost.
Subsequent test flights since August have planted over 3,100 trees with their drones, including White Spruce, White Pine, Blue Spruce, Red Maple, White Birch, Sugar Maple, Douglas Fir, and Balsam Fir.
Flash said it won’t focus exclusively on trees but other kinds of plants that compliment certain kinds of trees for ‘full ecosystem recovery.’
This summer, a Brazilian couple showed the power of reforestation when they showed the results of their own 20 year project to bring trees back to a 1,750-acre piece of land that had previously been used for cattle grazing.
The shocking results caused previously dry rivers to flow with water while more than 170 species of birds and 30 species of mammals returned to the forest cover after having previously departed due to lack of shelter and food sources.
...
WHAT IS REFORESTATION?

Reforestation is an initiative that intends to replant trees in areas that have seen significant loss of forest.
Forests are one of the most efficient ways to capture and store carbon dioxide, a common and important greenhouse gas.
Scientists believe that widespread reforestation initiatives could play a role in slowing or even reversing climate change by lowering the amount of carbon dioxide in the atmosphere.
Reforrestation has other benefits, including moderating local temperatures, increasing biodiversity, preventing water loss, and creating new forms of food sources.

We've sure been waiting for progress on batteries, it'd be cool if this was it but a betting man wouldn't put a ton of money on it yet.

Sounds awesome. To Ice’s point though, I feel like we keep hearing these stories but they don’t result in commercially viable products. Hope I’m wrong and cool article none the less.

**iceman** · 01-15-2020, 08:58 PM

It'd be a game changer for a lot of shit, particularly solar. I hope they nailed it.

Oh I agree completely. My use of "inching" was quite deliberate. But, that's how real technological progress gets made--incremental, iterative improvement that seems like its never going to go anywhere, until suddenly it's the new standard. The first Li-ion batteries were made in the '70s, as late as the early 2000s widespread commercial adoption was still basically a pipe-dream, and then by 2010 they were everywhere.
