Shiny mega-crystals that build themselves

June 3, 2021 by chambec · General Science

These new types of crystals are created all by themselves using weak forces that are many times weaker than those using typically found in crystalline structures like diamonds.

It appears that these new types of nanoscale building blocks will be useful in creating new ways to bond certain elements together. There may even be a higher level scientific advancement that can be achieved by studying the practical application of these self fulfilling structures. In addition, people may be able to learn more about how certain elements interact and bond with each other by studying the forces that lock these structures in place.

How Germs Spread (Coronavirus)

May 28, 2021 by villegse · General Science

Germs and how they spread!

Have you ever wondered how germs spread between people and animals? well, the thing is we can’t really see how to spread without a microscope or in this instance a powder called Glo germ, you need a black light to see the powder. For instance when using the powder to replicate as a germ “Mark” challenged himself to not touch his face. after a few hours he came back to see that he did however touch his face, proving a fact that no matter how much we resiste to touch our face it will somehow get on there.

This experement can go with phones aswell washing your hands can make a massive differnece in keeping yourself and other clean they recommend that you wash your hands at least 20 seconds or more to prevent you from catching anything. even though you can still get sick thorugh airborne sickness its a remeind to wash your hand and stay a resonalbe amount away from people. it doesnt really matter wether your Social or Anti-social.

Antibiotics from bacterial infections to fighting diseases.

May 25, 2021 by davisam · General Science

So, researchers at the University of Illinois Chicago are stating that antibiotics can serve another purpose to people as a treatment for human diseases. The reason this might be possible is the size, properties, and structure of cells. Some of these prescriptions can inhibit protein synthesis. If the proteins are inhibited the bacteria straight up dies. The root of many human diseases is caused by unwanted proteins.

If antibiotics start to treat these diseases eventually, we will be able to counter them then even prevent them. People won’t have to live in fear of hearing that they have a disease. The infected could live longer to impact the world. The life expectancies can rise again through the number of cases being ultimately being cured. All in all the world would just live better and long lives.

Asian butterfly populations show different mimicry patterns, thanks to genetic ‘switch’

May 25, 2021 by quirogfj · General Science

a study at the university of Chicago shows that there is a species of butterflies that can copy the patterns of other types of butterfly species. this happened due to the gene WntA that is know for its involvement is pigmentation. male and female butterflies that are sexually monomorphic mimic a genus of butterflies called Euploea that has black wings with light spots. there are also dimorphic butterflies which mimic two types of genus. males copy Euploea while females copy danaus which have orange colored wings.

Back Yard Squirrel Nut Heist

May 24, 2021 by demeteee · Biology

Cool video you should watch the original too

This is hilarious and entertaining. I wasn’t expecting the squirrels to get past the laser defense so easily. I thought it would be one of the most difficult but it seemed like they understood how it worked very quickly and got through. Rober’s inventions where just as impressive as the squirrels intelligence. The moving blocks and the lasers were a very impressive build. Before watching these videos I thought squirrels were just as dumb as a worm as it seemed like they wanted to get run over as I drive by. They decided to cross the rode just BEFORE I pass him. This video gives me a little bit more respect to the squirrel.

How it’s Made – Mirrors

May 24, 2021 by sarwanc · General Science

The video goes in-depth on the steps and processes that are put in place to successfully mass produce millions of quality mirrors every year. The mirror first starts out as a piece of glass. Firstly, the glass gets washed with brushes that use water and cerium oxide before being rinsed with hot demineralized water to avoid damaging the metals that are added next. Because silver doesn’t stick to glass, a layer of liquified tin is added before the liquified silver is applied. After the silver backing hardens, copper and paint are added to protect the silver in the long term. Following the application of both layers of paint, the mirror is heated in an oven and undergoes an acid wash to remove any residue. Finally, the mirror is inspected and cut into the desired size.

I found the process fascinating, especially due to how simple it is with modern-day technology. To see how chemistry plays a role in an everyday product really shows the underappreciation of something that is necessary for the way we conduct our everyday lives.

How Erasers Are Made

May 23, 2021 by taylorws · General Science

This video covers the process that is involved with creating erasers. Surprisingly, there are a lot of materials used for the common eraser, including fillers, accelerators, curing agents, oils, coloring, and synthetic rubber. The process of creating an eraser starts with a bunch of rubber being tossed into the center of two heated rollers. Manufactures use previously failed erasers in the new batch to be more efficient. After all of the erasers and rubber melt together, sulfur is added as a curing agent, and accelerators are added to supplement the sulfur, and then they add coloring. Vulcanized vegetable oil, and regular vegetable oil, and calcium carbonate as a filler are added. They are all blended together. The manufacturer then puts the new rubber into a furnace to make it compact. They are then cut out and prepared for the public to use.

I thought the process behind creating erasers was very interesting. I especially like that the people who make the erasers are as efficient as possible and re-use defective erasers. I always appreciate the lack of wasted material.

Did Grenade have more damage on the land?

May 21, 2021 by nialex · General Science

Here may be a lot of people for the first time such an idea, is the water there is resistance, grenade exploded in the water, because water resistance, so the grenade in lethality discount greatly, when the explosion, combined with the main killer grenade explosion is shrapnel damage, so, in this way, hand grenades in explosive power must be in the water than on land. However, although the grenade is the main production of explosive debris to kill the enemy, shrapnel in the impact of the action, really can do the land explosion killing than the water inside the big, do not forget, although the grenade is mainly debris killing, it is also a people ignored killing ability. This destruction ability is the shock wave, grenades in the underwater explosion while reducing the splintery killer, but, for killing would not reduce the shock wave, the opposite is also increased a lot, water is incompressible, so shock waves will directly impact to people’s body, so for the human body, damage effect will increase a lot.

Before I watched this video I always thought that grenades exploding on land would do more damage than underwater. But it wasn’t until I watched the whole video that I realized how much damage grenades can do underwater. On land, there might be a chance to avoid the shrapnel. There is no such chance in the water, where it will shatter your insides. So the next time you see a grenade, don’t duck under the water.

These squids can fly…no, really

May 21, 2021 by roycc · Biology

Small squids that are known to live deep beneath the waves. The squid can go above the sea about roughly around 50 meters. While only a few squids species have been recorded taking flight, most squids are alike in the way they service the ocean. The outside of a squids body is a massive tube of muscle called the mental, water enters through small opening around the squids head then the muscles clap the opening shuts and the squid forcefully pumps the water through the base of their body, in practice this makes the mantel a miniature jetpack. Propelling the squid throughout the water by 10km/hr. This is also a process on how squids breath. Squid gills rest inside the mantel and suffices oxygen from the water being passed.

I was fascinated on how squids can smash through the ocean surface and attempt a epic flight. With the resistance of the water, a squids acceleration is the same as the car going from 0 to 100 km/hr in just a second. At speed of 40km/hr, the squid quickly generates arrow dynamic lift but to stay in the air they would need something like wind.

Vultures: Can They Help Solve Crimes?

May 21, 2021 by mendozvg · Biology

This Ted Talk goes over the amazing capabilities of Vultures and the ways they can help humans. Lauren Pharr, who has spent years studying their behavior has finally figured out not only why vultures are able to find dead bodies, but how they do it.

Vultures have extremely strong acid in their stomach that makes it possible for them to digest human and non human bone. That is one of the reasons why their diet consists mainly of the bodies of dead animals. They use this skill and their incredible eyesight and smell to find their prey. Additionally, they are lured by the smell of brain matter and guts which makes them useful in finding victims of blunt force and head trauma.

I found this talk very useful. Vultures could truly speed up the process of finding the bodies of those missing.
