Immortality

I’ve just found out something amazing about certain lifeforms on earth. In particular, about one of the most delicious, priciest crustaceans out there, the Lobster! Turns out, lobsters are seemingly immortal. Other such creatures according to wikipedia would be bacteria, hydras, tardigrades and jellyfish but the largest would still be lobsters.

This is apparently because researchers have found that lobsters do not slow down, weaken or suffer reduced fertility. Their cells are rejuvenated and can theoretically live forever thanks to their DNA. If not eaten, injured, or killed, a lobster might actually continue living and growing which makes you wonder if there exists a huge lobster species in the ocean deeps.

Imagine if geneticist were able to give humans the same ability to constantly reproduce cells, would immortality be within our reach?

Human Echolocation

An article in September’s Reader’s Digest had an article about Human Echolocation which was amazing! It seems Brian Borowski who was born blind, has developed his senses to navigate the world through echolocation. Bats use echolocation by emitting a sound and waiting for the sound waves to bounce back in order to give the bat an ‘image’ of their environment. He emits clicking sounds with his tongue or jingles coins in his pockets to produce the sound he needs to create an echo.

According to scientists, everyday folks are able to utilize human echolocation but the only reason we are unable to is because we never developed our sense of hearing for that purpose. Practice makes perfect and someday we might evolve enough to be able to move about in the dark.

The person in the article was born blind therefore he didn’t really have an option but most probably for something to evolve with this ability, it would probably have to have a heavy dependency on it. Bats are apparently quite blind so sound helps them ‘see’ in a sense. There was also a documentary once about someone being able to ‘see’ through their skin. I’m guessing his sense of touch and feel is behaving like his eyes by feeling changes in the air currents and temperature around him to create an image in his brain.
