This week I’ve found a new source to feed my curious mind: Science Daily.
Usually, I’d go to YouTube and watch videos from SciShow, or from Ted Ed or Ted, or from Kurzgesagt. It’s easier to listen and watch animation when I want to learn something but nothing beats reading.
So this week, I’ll share some nerdgasmic things I’ve read from this new source I’ve been reading on. Got really excited while reading these! But I’m still sharing a few from the past sources. 🙂
They don’t have mouths to say “Hello” like Adele but they talk in ways that enables them to survive viral infections.
Like I’ve stated in my previous installment of Nerd’s Digest, our human bodies contain an ecosystem of bacterial colonies. These colonies thrive by helping us in digestion, mineral decomposition, and more – a symbiotic relationship.
Now imagine viruses that are not harmful to us but harmful to them (although I’m not sure there are viruses that do not harm humans). But in hypothesis, what if a virus eliminates these bacterial colonies that help us?
Unlike humans, single-celled organisms do not have complex immune systems. They have, instead, a way to protect itself from infections or diseases.
First, somewhat a similar way to how our cells create anti-bodies, is using CRISPR-Cas systems (you can Google this out and it’s pretty nerdgasmic, too!).
Second, a recently discovered way to protect the whole colony, is through quorum sensing. A research from University of Otago reveals that bacteria can sense through “talking” with one another using this form of chemical communication.
We all can agree that in order to survive, organisms will have to be in a community.
I guess no man really is an island.

CAPTURING AND SEALING CO2
Global Warming is not a political hoax and that I believe. I also believe that it is not a bad thing but it became bad because we humans have accelerated it faster than it should normally be.
When trees are not enough to balance out the carbon dioxide in the atmosphere, this greenhouse we live in now will eventually kill more species that the last mass extinction.
In efforts to substantially decrease the amount of carbon dioxide in the atmosphere, American Chemical Society unveils their almost 2-year long experiment where they’ve trapped CO2 in basalt and turned into solid rock.
If this is to be implemented in every country in the world, CO2 levels will plummet and the Earth will regain its supposed to be average global temperature.
Sounds cool to me. *pun intended*
FAST RADIO BURSTS
Fast Radio Bursts might be new to you. I know it’s something new to me. So I took time in researching.
Apparently, these bright pulses are generated outside our galaxy. They are intensely bright and outshines even the brightest star ever found. They only last for a millisecond. No one knows where they came from.
But despite their origins being a mystery, a recent FRB has everyone excited since it might explain the stuff that’s in between galaxies called the Cosmic Web.
“Because FRBs like the one we discovered occur billions of light-years away, they help us study the universe between us and them,” says Ravi, who is the R A and G B Millikan Postdoctoral Scholar in Astronomy. “Nearly half of all visible matter is thought to be thinly spread throughout intergalactic space. Although this matter is not normally visible to telescopes, it can be studied using FRBs.”
I know my words right there are like Star Wars jargon but it’s really exciting to know that there’s a way to know what the composition of the Cosmic Web is. It might also explain Dark Matter or Dark Energy (I am only assuming this out of my nerdgasm)
