Space.com reports on a new theory about how “abiogenesis” (the transition of ordinary stuff like water and dirt containing molecules into “life”) might have started on Earth. Previous theories suggest that the first self-replicating life form probably came to be randomly in some kind of primordial soup. But some interesting new theories have emerged that suggest that this process wasn’t random at all and was actually bound to happen because of two special thermodynamics concepts known as “entropy” and “equilibrium”.
If you’re a bit like me and you’re interested in chasing transcendental and other worldly experiences that are non-chemically induced, you might be interested in the following news.
Turns out our brains are actually capable of seeing colours that nature hasn’t shown us yet.
Ever wondered what a blue-ish yellow looks like? If you answered “green”, you are wrong! You can see what blue-ish yellow by staring at the blue and yellow image in this post, and letting your eyes cross so that both crosses appear on top of each other.
There are infact lots of colours that you haven’t seen yet. One is called “Stygian Blue” which is simultaneously both blue and black, and “Self Luminous Red” which is simultaneously red and brighter than white.
These are examples of colours that our eyes are incapable of seeing, but that can appear in our visual cortex by mixing signals between our two eyes. The following Wikipedia article contains some cool tricks that allow you to see them.
A popular theory in science is that life got started when a bunch of molecules randomly bumped together in a bubbling pool of water heated by a volcanic vent roughly 3.8 billion years ago. Now Some chemists at Cambridge have come close to explaining how that might have been possible:
“DNA is better known, but many researchers today believe that life on Earth got started with its cousin RNA, because that nucleic acid can act as both a repository of genetic information and a catalyst to speed up biochemical reactions. But those favoring this “RNA world” hypothesis have struggled for decades to explain how the molecule’s four building blocks could have arisen from the simpler compounds present during our planet’s early days. Now, chemists have identified simple reactions that, using the raw materials on early Earth, can synthesize close cousins of all four building blocks. The resemblance isn’t perfect, but it suggests scientists may be closing in on a plausible scenario for how life on Earth began. “
