The Feynman Technique

Weekly art tip: Drawing folds! 

Hope you guys enjoy it  I’ve put a lot work to make this ^^

I tried to make it as simple as possible :)

fun facts about sharks

As much as I want to support ethical farming practices I will be buying the cheapest bag of frozen chicken thighs as much as the next frugal/poor person which is why animal welfare needs to be legislated, not left up to the invisible hand of the free market or some bullshit. Invisible hand of the free market finds itself around a lot of throats.

Definitely toy story

I haven't looked into it, what's it about HD 186 302 that you like a lot?

We only have one example of how life formed. If we had even one other example, even if it was within our own solar system, it would vastly improve our understanding of how abiotic materials make the jump to biotic. But since we don’t have any other examples, all we have to go on is what we know about ourselves.

It comes down to the organic molecules which are the necessary building blocks for life as we know it. We’ve found them in protoplanetary disks— solar systems that haven’t finished forming.

An entire solar system forms together, all at about the same time, shortly after the star is born. For the most part, everything in a solar system will be made of roughly the same Stuff.

What this means is: the most likely place to find Earth-like life outside of our planet is within our own solar system.

It also means that second most likely place to find Earth-like life is in the solar system of our long-lost twin.

Recent studies have suggested that all stars are born in pairs. The vast majority of stars are actually binary systems, two stars orbiting around each other. Our solar system is an outlier. This doesn’t usually happen.

So…. where is our twin? Obviously, something happened and the stars got flung in wildly different directions. But a group of astronomers found 17,000 potential candidates, which they narrowed down to 55, and then to 4 stars that matched ours. And finally, HD 186302 was declared the most likely match. Unfortunately, we haven’t been able to detect any transits to see if it has planets yet…

….but the James Webb Telescope will be able to.

We’re still learning new things all the time, so it’s possible HD 186302 isn’t our solar sibling after all. Regardless, we have a solar twin out there somewhere, like another batch of cookies made from the same batter as ours.

The James Webb Telescope has me unreasonably excited for what amazing new discoveries we may potentially find.

Damn that's a big whale

This is why biology is important.

Worm Saliva Breaks Down Tough Plastic

Polyethylene, a durable plastic, is widely considered one of the worst forms of plastic pollution, but chemicals found the saliva of the wax worm may hold the key to breaking it down. One hours worth of exposure to the saliva breaks down the plastic by the equivalent of years worth of weathering.

There are two enzymes responsible for this degradation, and it’s believed that they are the first effective agents found in nature.

Polyethylene comprises 30% of production of a wide range of materials such as pipes, flooring, and bottles. Its hardiness comes from its resistance to oxygen. In order to get oxygen into the plastic, it has to be treated with UV light, but, the wax worms saliva seems to have a similar, if not improved, effect.

Wax worms are well known for destroying honey bee hives, and researchers say that its this ability to destroy hives that may hold the key to their ability to degrade plastics.

The study, published in the journal, Nature, is led by a team of Spanish researchers, who now want to research further into the degradation of polyethylene by wax worm saliva, and hope that one day, people may be able to have a home kit that they can use to breakdown the polyethylene at home.
