Question: Wikipedia article on rectal breathing

Answer: Rectal breathing is a technique for controlling the volume of air inhaled into the lungs by increasing the amount of air held in the rectum, thereby reducing the amount of air in the lungs. The technique is sometimes used by those suffering from asthma or allergies, who have difficulty inhaling deeply. It can also be used to reduce hyperventilation, as in anxiety attacks.

Rectal breathing is an ancient technique. It was described by the ancient Greek physician Galen in the second century CE, who wrote: "It is the best thing for a person who is affected by an asthma attack to make a fist and put his hand over his mouth and nose and then breathe through his rectum."

Rectal breathing is also sometimes used by competitive breath-hold divers, who can hold their breath for over 12 minutes. In order to reduce the amount of air in the lungs, and thus reduce the work of breathing, they hold a large volume of air in their rectum.

This is my jam!

AWESOME

the tumblr app is so broken my phone just wants to take it behind the woodshed and shoot it

i think "take a hike" is like the funniest response to someone. like dude just get outta here. and go experience the wonder of nature for a bit

Algae Street Lamps?

Fellow solarpunk genre fans, have you ever seen the algae-powered lamps? They were a popular topic back in 2013 when a man named Pierre Calleja suggested using them.

During the day, the algae uses C02 and sunlight to create energy through photosynthesis, and at night the lamp uses that stored energy to light the area.

" Basically, an algae lamp can remove as much CO2 in one year as a tree would in its lifetime." — Smithsonian Magazine

Using the natural energy reserves of algae may actually limit it's lifespan, so other companies are now looking towards bioluminescent algae. These algae glow naturally, so there is no need to syphon energy from them.

As of right now, those companies are still working on ways to make the glow brighter, but if it works, their blue lights could give a power-free way to light a street while the algae is also munching on C02.

Realistically, there are problems with algae lamps, such as:

How would it work in freezing climates?

How often the glass will need cleaning (though self-cleaning glass cold be an option)?

Would it put off enough light to be comparable to actual street lights?

For a fictional Solarpunk story, however, I think someone could easily make this work.

I don't know, I feel like if you call yourself a "super empath" you're the self-absorbed one in the situation

The exquisite sharpness of the NASA/ESA Hubble Space Telescope has plucked out an underlying population of infant stars embedded in the nebula NGC 346 that are still forming from gravitationally collapsing gas clouds. They have not yet ignited their hydrogen fuel to sustain nuclear fusion. The smallest of these infant stars is only half the mass of our Sun.

it is not everyday I think about frogs , although it is most of them .
