‘i refuse to accept pluto’s resignation as a planet.’- amy lee

Standard

 though not the first to go,

pluto lost its planetary status 15 years ago

 and not everyone agrees.

“as a planetary scientist, I don’t know what else to call Pluto: it’s big and round and thousands of miles wide.’ alan stern

out of thin air.

Standard

water from air

Two billion people on earth are without clean drinking water, and this problem will only be exacerbated by the climate crisis.

Fortunately, independent businesses are working on a myriad of differing solutions. One Israeli company, Watergen, has taken advantage of the fact that the Earth’s atmosphere contains 13 billion tonnes of fresh water and developed technology that filters water vapor out of the air.

Michael Mirilashvili, the leader of Watergen, told BBC, “A big advantage of using atmospheric water is that there’s no need to build water transportation, so no worries about heavy metals in pipes for example or cleaning contaminated water from the ground or polluting the planet with plastic bottles.”

The technology works by quickly drawing air into the machine and using condensation to produce fresh water at the low cost of seven to 15 cents per liter. The machine does use electricity, but if this can be supplied via renewable sources, the machine would have a very little environmental impact.

Water gathered from the atmosphere still faces the issue of condensing air pollution. Although lead was banned in 1999, it is still found in UK air in 2021. However, partner researchers from Tel Aviv University proved this to be a small obstacle when they were able to extract the water to a quality set by the World Health Organization.

Watergen’s technology can provide up to 1,585 gallons of water per day and has already been used at hospitals in the Gaza Strip and villages in Central Africa.

think pink.

Standard

Today in animals you might not believe are real (but are!): the pink fairy armadillo. This species (Chlamyphorus truncatus) grows to just about 6 inches long, making them the smallest armadillos in the world.

They are found only in central Argentina, and because they’re nocturnal and spend a lot of time burrowing underground, the elusive creatures are difficult to study. 

Like other armadillos, pink fairy armadillos have a shell (or carapace) but theirs is softer, thinner and more flexible. The shell’s color comes from blood vessels close to the surface.

some animals are so unusual, it’s hard to believe they’re real.

what’s the most interesting/unusual animal you’ve ever encountered?

butterflies are free.

Standard

after one final close look 

at the butterflies we raised

it’s time to release them back into nature

where they quickly find their wings. 

 

“the butterfly counts not months but moments, and has time enough.”

tulips.

Standard

*”tulips are the only flowers that continue to grow, up to an inch or more, after they’re cut.”

-sarah jio

 

i find it fascinating that they refuse to surrender so easily

even defiantly growing longer 

and,

there’s science.

 

*Tulip stems do continue to lengthen once they’re snipped. That’s because the cells in their stems are particularly responsive to the plant hormone auxin, which causes them to elongate. Auxin also influences phototropism — the tendency of plants to grow toward light. – google

the music of spiders.

Standard

spider music

The humble spider has always been well represented in the musical world, from Ziggy Stardust to the Who and Wilco. For too long, though, we’ve refused to let them relate their experiences to us more directly. That’s now changed, thanks to the work of scientists who are turning spiders’ vibration-based perceptions into music.

Vice recently profiled the work of MIT engineering professor Markus Buehler, who leads a team that’s working to translate web vibrations into sounds we can actually hear. The project uses “the physics of spiderwebs to assign audible tones to a given string’s unique tension and vibration” through a process called data sonification.

The resulting models can be explored through virtual reality software or listened to via examples recorded by Buehler and his collaborator Tomas Saraceno. The music created by manipulating the models is incredible—an eerie approximation of how spiders understand their environments.

Buehler says that the project’s goal is both to “expand how we generate sound in music and how we compose music” and to practically demonstrate how “for something like a spider, there’s a whole different way of experiencing the world.”

“Researchers say the project could eventually be used to reverse engineer spiders’ reality and communicate with the arachnids,” Vice explains, somewhat ominously. Buehler elaborates, saying that he’s planning to play AI-generated spider sounds to the creatures and “gauge [their] reactions.”
