A “sub”lime underwater weapon

Last weekend, my uncle and I hopped on a plane and visited OMSI (the Oregon Museum of Science and Industry).

Along with their indoor exhibits, the museum’s grounds also harbored a decommissioned submarine, the USS Blueback. After purchasing tour tickets, I got to explore the inside of the boat and learn about each of its different rooms.

One of my highlights from the tour was the torpedo room, which I found to be the most comfortable and coldest room aboard the Blueback — necessary to preserve the missile’s fettle. …

Your sanguinary sacrifice will not be in vein!

Humans have been exploring Mars since the 1960s. Today, colonizing the Red Planet remains at the forefront of the world’s outer space missions.

However, building a Martian colony is no easy feat.

One major problem scientists have faced is finding the resources to continually build new settlements. Simply shipping loads of bricks between Earth and Mars is far too expensive and unsustainable. Even shipping a single brick to Mars can cost up to 2 million USD!

Instead, colonists must find a way to live off of Mars’ natural resources and any items that they bring with them.

That includes the…

Don’t worry — it’s (mostly) normal!

Right now, there are thousands of “bugs” crawling all over your face. These critters, known as face mites or demodex mites, are transparent in color and microscopic in size, making them invisible to the naked eye.
But, just because you can’t see them doesn’t mean that they don’t exist!

With the help of a microscope, scientists can confirm the presence of face mite populations and see what they look like up close. Microscopic images show that face mites have long, scaly bodies paired with four sets of pudgy legs, reminiscent of their distant cousin, the spider.

Fittingly, face mites belong…

How to steal from a black hole

The name “black hole” is really a misnomer. If you do a quick Google search, you’ll find out that black holes aren’t black, but invisible.

The attribution of black, dark, and shadowy characteristics to the black hole is quite unfounded. In reality, black holes are super bright, surging with enormous energy.

An active black hole creates a spiral trail that encircles itself, which is known as an accretion disk. Accretion disks accrete, or accumulate, various gases and dust that the black hole sucks in.

The accretion disk itself rotates at almost the speed of light, with its contents constantly colliding…

Space tourism is hot, but the climate is even hotter!

“What contributes to climate change?” When I posed this question to a group of climate change activists, many of the answers that I received were the same.

Power plants was one of the most predominant answers. In an interview, one activist explained to me that most power plants burn fossil fuels (like coal or oil) to produce heat and electricity. The burning of these fossil fuels is problematic because of the subsequent releases of greenhouse gases, such as carbon dioxide. In turn, increased concentrations of greenhouse gases trap heat inside of our atmosphere, warming up the entire planet.

Is the cure for Alzheimer’s underwater?

The octopus isn’t the only kind of camouflaging cephalopod.

Cuttlefish, or “cuttles” for short, have the same wacky ability to imitate their surroundings.

To do this, cuttlefish have millions of special skin cells called chromatophores. Each chromatophore contains a mini, elastic sac filled with red, yellow, or brown colored pigment.

Opening and closing these sacs occurs when a cuttlefish contracts or relaxes their muscles. This makes it possible for the cuttlefish to control the contrast of their skin coloring:

When muscle fibers pull open the sac, the pigment expands, causing the color to spill out across the skin (higher contrast)…

Ms A had been enduring bipolar affective disorder for 35 years. At 62 years old, she experienced a devastating relapse and her mental health began to decline dramatically.

Her returning affective bipolar disorder caused her to alternate between extreme emotional highs and lows, depending on her mood.

Ms A’s “lows” or depressive states beset her day-to-day life, making it hard to socialize or partake in activities she used to enjoy. As her symptoms worsened, Ms A also developed feelings of worthlessness, neglecting to take care of herself or eat properly.

Furthermore, Ms A developed psychomotor retardation as a result of…

Astronomers just found something really weird.

Milky Way: a perfect blend of fluffy nougat and silky caramel, delicately wrapped in a smooth layer of milk chocolate. Oh, and the name of the galaxy that we call home!

Our beloved Milky Way galaxy measures 100,000 light years in diameter, making it the second largest galaxy in our “neighborhood”, also known as the Local Group. (The largest galaxy is the Andromeda Galaxy at a whopping 220,000 light years.)

Within the Local Group, the Milky Way is one of over 50 different galaxies that each have their own unique shapes and systems. …

According to Einstein’s general relativity theory, gravity is a distortion of space. Rather than a force that controls an object’s pushes and pulls, the force of gravity is a by-product of the object itself. The more mass an object has, the more it distorts space.

Along with its definition of gravity, general relativity theory also predicted the astronomical phenomenon known as “microlensing.”

Microlensing involves an interaction between a star and a second space object. When an object passes by a star, both objects are bending their surrounding fabric space-time. …

Rules are meant to be broken

The 60–30–10 rule is well known across a diverse community of designers. For UI designers, interior home designers, and fashion designers, this famous rule has been tried and true.

The purpose of the 60–30–10 rule is to help introduce and balance colors. The idea is that 60% of your design should be a single, neutral color. This serves as a base or an anchor. 30% of your palette should be a secondary color that complements the 60% chunk. Finally, the remaining 10% should be set aside for the accent color.

Using this policy has numerous benefits. By limiting the number…
