This lamp absorbs 150 times more CO2 than a tree
It’s still in the “so crazy it just might work” stage, but these microalgae-powered lamps, invented by French biochemist Pierre Calleja, could absorb a ton of carbon from the air every year. That’s as much as 150 to 200 trees. [x]
YOU DON’T UNDERSTAND. This is ingenious.
The design is a light bulb surrounded by a glass casing. The glass is filled with (water based) media and microalgae. The top is permeable to gasses so that gas exchange can occur. All of the wiring is linked to the grid underground.
Since the light source is inside, it gets scattered and “dimmed” by the water and algae. This makes it less glaringly bright and scatters the light wider, which is good for a street light. It is not longer white light as well, which helps make it easier on the eyes while still providing light.
At the same time, it provides the light for photosynthesis in the algae, so they are continuously exchanging CO2 for O2, not just in the day. It also provides a source of heat, which helps keep the algae from going dormant during cold weather (as in the snowy picture above).
And notice how I did not specify permeability - that’s because NOx’s (NO and NO2) are also permeable and can be used as nitrogen sources to microalgae. In fact, algae are relatively low maintenance. As autotrophs, they don’t require super complex media, not does it really need to be changed/added to. (I’m actually fairly certain that there would still be algae in these tanks a year later; it may need to be cleaned or something, but there would be some living algae.)
If you aren’t totally quaking in your boots at the news of millions of bees dead, yet again, you’re nuts.
this should be concerning a lot more people than it is
not only because bees are one of the most important animals in the world and their job is a lot more than gathering honey but also because they are what scientists refer to as an “indicator species”
this means that when their populations start dwindling and then rapidly dropping, humans need to watch their shit because that means that environmental factors are too difficult for THEM to live in, so it might be difficult for US to live in, too. bees basically act as an indication that humans have a lot to worry about and when they start dying like this it deserves a lot more than a few headlines.
last year my biggest worry was the steep decline in bee population and apparently thats not about to change anytime soon. people have told me to my face that they think its strange I’m so concerned for the bees. read this you selfish fucks
Get excited, motherfuckers. Without bees, we will die off. Bayer and Monsanto continue to produce the chemicals that have been proven to kill them, and the government has their backs. Bees pollinate 30% of our food in the US and we are passing legislation to PROTECT the scumbags responsible for killing them.
I preach this shit to everyone who will listen and I always get “WAAAAH I HATE BEES THEY STING AND THEY ARE BIG MEANIES!” but think about your future life without kiwis, cranberries, blueberries, strawberries, blackberries, peaches, sunflowers, cotton, apples, plums, pears, mustard, celery, peppers, tomatoes, eggplant, beans, cherries, melons, turnips, canola oil, alfalfa, soybeans, lemons, oranges, and I could go on forever.
Bees are amazing creatures who are responsible for the comfortable lives we lead in this country and we cannot sustain and feed our population without them.
Alright you guys, there’s a good amount of notes on this but it’s only making us aware of the problem, not telling us what we can do to help. We can do something to help and YOU CAN HELP, YES THAT MEANS YOU. ALL YOU NEED IS DIRT, A FEW BUCKS, AND A MOMENT OF YOUR TIME TO MAKE A WORLD OF DIFFERENCE, LITERALLY.
Plant flowers that bees like and that attract them.
Bees prefer flowers that are blue, purple, and yellow. Choose flowers that bloom successively over the spring, summer, and fall seasons such as coreopsis, Russian sage, or germander. They especially love clover! Other plants include sage, salvia, oregano, lavender, ironweed, yarrow, yellow hyssop, alfalfa, honeywort, dragonhead, echinacea, bee balm, buttercup, goldenrod and English thyme. Buy seeds online.
GET RID OF THE PESTICIDES!!
If pesticides are killing off the bees so easily, what do you think it’s doing to us? The EPA says studies have shown pesticides can cause birth defects, nerve damage, and cancer. There are other ways to get rid of pests in the garden than using chemicals. Organic Garden Pests shows you how to keep off the bugs the organic way.
Give the bees a free home!
Please, if you have already reblogged this, reblog this is again with what I have posted onto it so you know what you can do to help. We can make a difference.

Guys, if all the bees died we’d have FOUR YEARS to live.
Today is Copernicus’s 541th birthday. You may remember Copernicus as the man who said “Hey, what if the Earth went around the sun?” To which the Catholic Church replied “Hey, what if we set you on fire?”
Astronaut John H. Glenn, Jr. became the first American to orbit the Earth on February 20, 1962. With the world watching the historic and live-televised event, Glenn orbited the Earth three times in his space capsule, Friendship 7. Four hours and 55 minutes after ignition, John Glenn and Friendship 7 returned to Earth and splashed down in the Atlantic Ocean.

Ladies and gentlemen, I could not make this up if I tried. I owe my thanks to Wyatt Patry for sharing this study with me, and to P. Zelda Montoya and Barrett L. Christie at the The Dallas Zoo and Children’s Aquarium for creating “the first known unholy amalgamation of America’s favorite lunchtime treat and live cnidarians”. That’s right folks, on the earth right now are, in fact, peanut butter jellyfish.
“We would love to claim we conducted this trial with noble purpose” Montoya and Christie say, “but the truth is that we just wanted to make peanut butter and jellyfish simply to see if it could be done”. So to carry out this mission, they gathered up 250 baby moon jellies and some creamy peanut butter (no additives, of course!). They blended peanut butter and saltwater, then added small drops of the peanutty liquid twice daily to the baby moon aquarium.
The authors expected many things to happen. But the moon jellies eating peanut butter was not one of them. To everyone’s complete shock, however, that’s precisely what happened. ”Mean size had increased to 4.17±1.06mm (n=19) after 8 days of peanutbutterification” the authors write. In other words, the peanut butter jellies were actually growing. And better yet, they became little peanut butter jelly cups: “Throughout this period it was noted that jellies that had recently fed displayed a distinct brownish hue owing to their high degree of peanutbutterocity.”
The authors conclusion? “Moon jellies have seen a storied past. They have delighted children at aquaria worldwide, captivated researchers with their elegant simplicity and functionality, and even traveled into space (Spangenberg, 1994); but we feel that becoming one with peanut butter helps them fulfill their ultimate destiny as a species – to become peanut butter and jellyfish!”
These people. I want to be friends with them. I want to be friends with them now.

January 27, 1967: Apollo 1 Practice Launch Ends in Tragedy
On this day in 1967, tragedy struck the space program. Gus Grissom, Ed White and Roger Chaffee had been selected as the crew for Apollo 1, the first flight of the next generation of spacecraft succeeding the Gemini program.
During a practice launch countdown, a flash fire erupted inside the sealed cockpit. Within seconds the men were unconscious; minutes later they were dead. Because of the pressure of the fire, and the fact that the spacecraft’s hatch opened inward, there was no hope of escape.

Rising Sun forming the Greek letter omega also known as an Etruscan vase shape. This omega shape is a type of inferior mirage. The refracted (inverted) image is actually below the object’s true position. When the Sun protrudes above the horizon at sunrise, its inferior mirage can sometimes be seen below it, where it joins the true Sun, creating the familiar omega shape as seen in the second and third image from the left. For this mirage to occur, a layer of very warm air must lie just above the sea surface.
During the Bubonic Plague, doctors wore these bird-like masks to avoid becoming sick. They would fill the beaks with spices and rose petals, so they wouldn’t have to smell the rotting bodies.
A theory during the Bubonic Plague was that the plague was caused by evil spirits. To scare the spirits away, the masks were intentionally designed to be creepy.
Mission fucking accomplished
Okay so I love this but it doesn’t cover the half of why the design is awesome and actually borders on making sense.
It wasn’t just that they didn’t want to smell the infected and dead, they thought it was crucial to protecting themselves. They had no way of knowing about what actually caused the plague, and so one of the other theories was that the smell of the infected all by itself was evil and could transmit the plague. So not only would they fill their masks with aromatic herbs and flowers, they would also burn fires in public areas, so that the smell of the smoke would “clear the air”. This all related to the miasma theory of contagion, which was one of the major theories out there until the 19th century. And it makes sense, in a way. Plague victims smelled awful, and there’s a general correlation between horrible septic smells and getting horribly sick if you’re around what causes them for too long.
You can see now that we’ve got two different theories as to what caused the plague that were worked into the design. That’s because the whole thing was an attempt by the doctors to cover as many bases as they could think of, and we’re still not done.
The glass eyepieces. They were either darkened or red, not something you generally want to have to contend with when examining patients. But the plague might be spread by eye contact via the evil eye, so best to ward that off too.
The illustration shows a doctor holding a stick. This was an examination tool, that helped the doctors keep some distance between themselves and the infected. They already had gloves on, but the extra level of separation was apparently deemed necessary. You could even take a pulse with it. Or keep people the fuck away from you, which was apparently a documented use.
Finally, the robe. It’s not just to look fancy, the cloth was waxed, as were all of the rest of their clothes. What’s one of the properties of wax? Water-based fluids aren’t absorbed by it. This was the closest you could get to a sterile, fully protecting garment back then. Because at least one person along the line was smart enough to think “Gee, I’d really rather not have the stuff coming out of those weeping sores anywhere on my person”.
So between all of these there’s a real sense that a lot of real thought was put into making sure the doctors were protected, even if they couldn’t exactly be sure from what. They worked with what information they had. And frankly, it’s a great design given what was available! You limit exposure to aspirated liquids, limit exposure to contaminated liquids already present, you limit contact with the infected. You also don’t give fleas any really good place to hop onto. That’s actually useful.
Beyond that, there were contracts the doctors would sign before they even got near a patient. They were to be under quarantine themselves, they wouldn’t treat patients without a custodian monitoring them and helping when something had to be physically contacted, and they would not treat non-plague patients for the duration. There was an actual system in place by the time the plague doctors really became a thing to make sure they didn’t infect anyone either.
These guys were the product of the scientific process at work, and the scientific process made a b****in’ proto-hazmat suit. And containment protocols!

The Most Rare Colored Fruit
The tiny, rock-hard fruits of Pollia condensata, a wild plant that grows in the forests of several African countries, can’t be eaten. But they have an extremely rare property for a plant. They stay vibrant, metallic blue for many decades, even after they’ve been picked. They produce the most intense color ever studied in biological tissue.
The vast majority of colors in the biological world are produced by pigments—compounds produced by a living organism that selectively absorb certain wavelengths of light, so that they appear to be the color of whichever wavelengths they reflect.
However, Pollia condensata produces its vibrant blue color through nanoscale-sized cellulose strands that scatter light as they interact with one another. Thus the fruit’s color is visible at the cellular level as pictured above.
