Spidey Sense, for Drones?

May 22, 2019 by martindm · General Science

Scientists are attempting to steal some of natures ideas, and adapt them to work with machines. They want to give machines the ability to sense things faster and increase machines information processing speed. The inspiration for these ideas come from animals like spiders, bats, and birds, etc. A great example of the power these animals hold would be the spider. Spiders have several stiff hairs on their legs which increase their sensitivity. Allowing them to sense when even the smallest critter wanders into their web. Those hairs allow them to detect lower frequencies and vibrations.

With these abilities, machines could make up for humans many faults. This could help prevent so many accidents from happening. Car accidents and other terrible accidents could be a thing of the past. A rare and uncommon tragedy. this could lead to a great decrease in deaths involving cars and other machinery.

Giant Impact Caused Difference between Moon’s Hemispheres

May 22, 2019 by kennedrt · General Science

There are a number of ideas that have been used to try and explain the Moon’s asymmetry. There are too many planets orbiting the earth.
Another idea is that a large body, perhaps a young dwarf planet, found itself in an orbit around the Sun that put it on a collision course with the Moon. Signs of a disaster like this should be visible on the lunar crust.
Under both these scenarios, the model shows the impact would have thrown up vast amounts of material that would fall back on the Moon’s surface, burying the primordial crust on the far side in 3 to 6 of debris. That is the added layer of crust detected on the far side by GRAIL, according to Zhu.

I think this is incredible because who of expected this no one would have expected and we wouldn’t of have been able to figure it out if it wasn’t for our technology. We are so advanced now that we can do anything if we try hard enough. And we have the most tech to help us throughout all our stuff.

Dogs’ Personalities Can Change Over Time, New Study Suggests

May 21, 2019 by liuy · Biology

In a sample of 1,681 dogs, Chopik & Weaver found reliable age differences in dog personality.

As human beings, we all know that people’s personalities can be changed due to the experience, environment, time, and so on. However, we seldom think about other animals’ personalities would change because of some reason or not. A study published in the Journal of Research in Personality, a duo of researchers from Michigan State University found that this also happens with dogs. They found that not only the surroundings will have influences on dog’s personalities, but also the dog’s feeder’s personalities and behaviors will lead to the change of dog’s personalities.

It is a really interesting observation since we treat dogs as good friends or family members but not a lot of people will pay attention to dogs’ changes in personalities. It is really meaningful that you feed a puppy and grow with him/her, both of your personalities will be positive and be promoted. I really wish that I can have a dog in the future, then my life would be more fun.

Wormhole

May 20, 2019 by qiuhh · General Science

This is a wormhole.

The Wormhole (also known as the Einstein-Rosen Bridge) is also translated as a pupil. It is a narrow tunnel that may exist in the universe connecting two different time and space. The wormhole was first proposed by the Austrian physicist Ludwig Flem in 1916. It was assumed by Einstein and Nathan Rosen in the study of the gravitational field equation in 1930 that it can be done through wormholes. Instantaneous space transfer or time travel.

In my opinion, if the wormhole can be used by humans, then there is no problem with Star Trek.

Black Holes

May 20, 2019 by qiuhr · General Science

A black hole is a kind of celestial body in the modern general relativity. The gravity of the black hole is so great that the escape velocity within the event horizon is greater than the speed of light. A black hole is an object whose curvature is so great that light cannot escape from its event horizon.

Black holes cannot be directly observed, but their existence and mass can be known indirectly and their effects on other things can be observed. Information about the existence of black holes can be obtained by “edge information” of gamma and gamma rays emitted by the object before it is inhaled. The existence of black holes can also be inferred from indirect observations of the orbits of stars or interstellar clouds for location and mass.

I think According to general relativity, the stronger the gravity, the slower time is. The less gravity, the faster time. Since our earth has a small mass, the gravitational force does not change much from one place to another, so the time difference is not big. The top of the Himalayas, for example, is only a few hundred billionths of a second from the bottom. Because black holes are massive, gravity varies enormously from one place to another, so the time difference is huge. If the Himalayas are around a black hole, when a bunch of mountaineers starts from the bottom of the mountain, let’s say they’re in 2005. When they reached the summit, they found the top was 2000 years old.

Viable, Environmentally-Friendly Alternative to Styrofoam

May 20, 2019 by ehingecg · Chemistry

A new plant-based material has been recently discovered by researchers at Washington State University that has been found to have better insulation than styrofoam. The new material is mainly made up of nanocrystal of cellulose, which is one of the most abundant plants on Earth. Also with the new discovery of this foam researchers have also advanced the process of making it more simple and less harmful by using water as a solvent instead if other chemical solvents used in the process of typical styrofoam. This new replacement for styrofoam will be monumental. The popular material of styrofoam is used in almost everything from coffee cups to packaging and even in construction. The main problem is the toxic ingredients that go into the making of the styrofoam as well as the fact that they do not decompose naturally which further creates pollution in the air.

This is a very intriguing article because right now there is a high attention on creating new and better materials that provide more Earth friendly materials. This new material I think could personally benefit the Earth in many ways and I am excited for the further research to be done and expanded on.

New genetic ‘risk score’ could predict obesity odds

May 20, 2019 by luleo · Biology

Researchers say they can analyze DNA’s variations to predict who is most at risk of becoming obese. The new genetic risk score provides the best DNA-based forecast yet for obesity. But researchers also warn that the score has serious limitations, as it only suggests a likely weight range—and a wide one—for each person. They look for in genomes of more than 300,000. Then, they compared that with the known weights and BMI of those people, calculated the impact of each variant on BMI, and integrated that information into a single number, called a “polygenic risk score.”

This is a new way that people can predict whether you are obese or not. This research helps people work on their health before obese happened.

Scientists Have Discovered a Reliable Way to Patch up Leaking Arteries

May 20, 2019 by feistsm · Biology, Chemistry

Researchers in China have created a hydrogel that can close a punctured wound, including arteries. They say it takes about twenty to thirty seconds to heal it using this method. A standard method of closing a punctured artery during surgery means clamping the artery and using sutures to close it. Compared to other hydrogels that are made of toxic materials, this new substance is made of water, gelatin, and a mix of proteins and other chemicals. This means that this specific process is far safer than other methods.

This is an exciting development because it will inevitably lead to safer surgeries, which has the potential to save many, many lives. If a surgeon makes a mistake, then it can be solved much easier than it normally would. When I watched the video of the hydrogel in action, I was simply amazed at how easy it was to use and just how quickly it healed the wound. Hopefully, these researchers will release the magic gel into the rest of the world to allow everyone to have access to safer surgeries.

Yellowstone Elk Don’t Budge for Wolves Say Scientists

May 20, 2019 by chambec · Biology

Recently, studies at Yellowstone park have revealed that the elk no longer abandon their living area during wolf attacks. They have been seen using antipredator tactics such as grouping, outrunning the wolves in the area, and fighting the wolves directly. The reason that the elk are not willing to move for the wolves is because they are philopatric animals, which means that they tend to return to the same wintering and summering areas year after year. The scientists have also discovered Elk becoming more aggressive one such researcher said this: “Elk in their prime do not have a massive incentive to avoid wolves…”

Methane-Consuming Bacteria Could Be the Future of Fuel

May 20, 2019 by tumanbm · Chemistry

A team from the Northwestern University in the US found that the enzyme responsible for the methane-methanol conversion catalyzes this reaction at a site that contains just one copper ion. The finding could lead to human-made catalysts that convert methane to methanol effortlessly. ‘”The identity and structure of the metal ions responsible for catalysis have remained elusive for decades,” said Northwestern’s Amy C. Rosenzweig, co-senior author of the study. “Our study provides a major leap forward in understanding how bacteria methane-to-methanol conversion.”‘

This is a very important finding, mainly because methanol is a clean-burning fuel. It can be used as a substitute for gasoline for fuel in cars. Methanol can also be used as antifreeze. It will be intriguing to see where to research goes, hopefully, we can find a great, renewable fuel source.
