The Carina Nebula - A Birthplace Of Stars

The Carina Nebula lies at an estimated distance of 6,500 to 10,000 light years away from Earth in the constellation Carina. This nebula is one of the most well studied in astrophysics and has a high rate of star formation. The star-burst in the Carina region started around three million years ago when the nebula’s first generation of newborn stars condensed and ignited in the middle of a huge cloud of cold molecular hydrogen. Radiation from these stars carved out an expanding bubble of hot gas. The island-like clumps of dark clouds scattered across the nebula are nodules of dust and gas that are resisting being eaten away by photons (particles of light) that are ionizing the surrounding gas (giving it an electrical charge).

MBTI Studying Tips - Part 1

DISCLAIMERS: 

What I did do: Collect information and organize them into an easy-to-read-and-understand-post. What I didn’t do: Write most of it. Most of the information here isn’t my own writing, but rather useful tips I found from various sources. Credit is given at the bottom of the post.

I wrote most of this by doing a hell lot of research online and trying to ask my friends of different types irl what they thought of it. I am no professional, and my words in no way should be taken as gospel. Please, please send me corrections or your thoughts if anything I wrote was inaccurate, I will appreciate all the feedback I can get.

Hello hello! Your old friend Skye is here with some tips for studying based on your MBTI personality type. Now before we jump straight into things, let’s answer a few basic questions:

What is MBTI?

MBTI stands for the Myers-Briggs Type Indicator, which is basically a personality test that classifies you into one of 16 different personality categories based on a four-letter code. This is what the “INFP” or “ESFJ” codes mean if you’ve been seeing them around in the community. The test assesses you on four of your main traits:

How do you prefer to direct your energy? (I vs E)

What kind of information do you prefer to gather? (S vs N)

What criteria do you prefer for making decisions? (T vs F)

What kind of environment do you prefer? (J vs P)

So how do I find out what’s my type?

You can take a free online quiz here!

Okay, but what’s with the ‘Introverted Thinking’ and ‘Fi’ and all the fancy terms?

You can read more about Cognitive Function Theory here! I will be basing my post off this theory because I think it’s a more comprehensive method of understanding MBTI. 

Onwards! (The rest is under the cut bc skye rambled and it’s long af even tho I’m just covering the introverted functions)

It’s Surprisingly Easy To Brew Something Like RNA In A Puddle 

One of the biggest mysteries in science is how you could get life in a place where it doesn’t already exist. Scientists have found some clues, though.

The latest is that Georgia Tech chemist Nicholas Hud was able to create something that looks a lot like RNA — a relative of DNA — using ingredients that would have been common on Earth when it was 4 billion years younger.

The study used two common chemicals left alone in what amounts to a mud puddle. The chemicals synced up and started forming that twisting ladder shape we think of when we picture DNA.

Scientists say this looks like a decent candidate for how simple organisms may have gotten started on Earth, and it wasn’t even all that hard.

Earlier studies have shown you can get some of the building blocks of life in the right situation, like extreme heat or lightning strikes. Some have even been found on asteroids.

The Georgia Tech study shows you don’t even need that much excitement. Swirling puddles could potentially have done the job.

Antibodies are the secreted form of B-lymphocyte receptors and are a part of adaptive immunity, but how are these proteins formed?

Above is a diagram illustrating Paul Ehlrich’s Side Chain Theory of Antibody Formation. Ehlrich proposed that immunoglobulin molecules, a fundamental component of adaptive immunity, served as membrane bound proteins that bound to particular threats, similarly to the former “key in lock” view of enzymes in catalyzing biological reactions. Ehrlich also suggested that the action of binding a pathogenic molecule to the receptor would generate a signal to stimulate the production of more receptors of the same specificity. These “side chains” that were added on would then break off from the cell surface and become what we call antibodies.

 We now know, however, that soluble immunoglobulin receptors are specially manufactured to be secreted as antibody, rather than just “breaking off” of the lymphocyte, even though they have the same specificity as their membrane-bound counterparts.

WOW!!

This computer-simulated image shows a supermassive black hole at the core of a galaxy. The black region in the center represents the black hole’s event horizon, where no light can escape the massive object’s gravitational grip. The black hole’s powerful gravity distorts space around it like a funhouse mirror. Light from background stars is stretched and smeared as the stars skim by the black hole.

Science When the Sun Don’t Shine

About once a year, somewhere on Earth, the sun is blocked by the moon. This phenomenon – called a total solar eclipse – is one of the most beautiful natural events.

Blocking the light of the sun during a total solar eclipse reveals the sun’s relatively faint, feathery atmosphere, called the corona. The corona is one of the most interesting parts of the sun. We usually study it using an instrument called a coronagraph, which uses a solid disk to make an artificial eclipse by blocking the sun’s face.

To successfully block all of the sun’s bright light – which can bend around the sharp edges of a coronagraph disk – coronagraphs must block much more than just the face of the sun.  So total solar eclipses are a rare chance to study the lower part of the corona, close to the surface of the sun.   

We have sent a team of scientists to Indonesia, where they’re preparing for an experiment during the March 8, 2016, eclipse, visible from Southeast Asia.

The scientists are measuring a certain kind of light – called polarized light – scattered by electrons in the lower corona, which will help us understand the temperature and speed of these electrons.

The March 8 eclipse is a preview of the total solar eclipse that will be visible across the US in August 2017.

Remember, you should never look directly at the sun – even if the sun is partly obscured. This also applies during a total eclipse up until the time when the sun is completely and totally blocked. More on safety: http://go.nasa.gov/1L6xpnI
