Graphene could give us the electronics of the future much faster

New experiments presented in Nature magazine seem to show that this substance composed of a single layer of carbon atoms can transform electronic signals transmitted in gigahertz into higher frequency signals. We are talking about terahertz, capable of carrying up to 1,000 times more information per second. Electromagnetic waves in the terahertz range are notoriously difficult to create and conventional silicon-based electronics have trouble...

Why did the FBI suddenly evacuated the space observatory in New Mexico?

National Solar Observatory (NSO) in Sunspot, New Mexico, was shut down by FBI agents earlier this month (September 2018) due to security concerns, but the facility was reopened later on. Even so, many of us are wondering what are the reasons behind this action. At present, the solar observatory no longer represents a security issue, but conspiracy theorists are not relaxed on this particular topic. According to AURA (Association of Universities...

Scientists created the first human esophagus made from stem cells

Bioengineering scientists working to produce the entire human gastrointestinal system in the laboratory reported that pluripotent stem cells were used to create a human esophagus. This is the first time scientists have been able to grow human pluripotent stem cell (PSC) esophageal tissue, cells that theoretically can form any type of body tissue. Published in the Cell Stem Cell diary, the study presents the latest innovatotion from researchers...

Are infrared radiant heating panels beneficial to health?

Infrared radiant heating panels are being promoted aggressively recently. Marketeers say about these device that they represent a safe way to reduce the heating bill. Some will go one step further and say that they have "miraculous therapeutic effects". Of course, all these alleged health benefits does not have a reputable scientific study to back the claims but hey... if it is cheap and it works, people will buy them regardless. Among the...

A large asteroid will be approaching Earth in just few days

NASA has released a warning on an asteroid that is considered to be "potentially dangerous". The space object is called 2016 NF23 and it will pass near our planet on August 29, at a distance of 13.4 times the distance between the Moon to Earth. That's more than three million miles (4.8million km) or just 0.03377 astronomical units In astronomical terms, this means that it will pass near us, hence the cataloging of the asteroid as "potentially...

An alarming phenomenon will occur at the North Pole!

Due to global warming, the permafrost (the soil that should always be frozen) in the Arctic does not freeze anymore during winter. Thus, it remains damp and humming. Researchers have noticed this phenomenon and they draw attention to the danger this phenomenon pose. Permafrost stores billions of tons of carbon, which will reach the atmosphere in the form of greenhouse gases: methane and carbon dioxide. The release of these gases will have add an...

Blue light emitted by smartphones and tablets can lead to vision issues

A team of scientists at the University of Toledo in the United States has revealed that prolonged exposure to blue light triggers the release of toxic molecules in photoreceptor cells that, in time, could lead to vision issues. In time, this can lead to macular degeneration, an ophthalmic disorder that causes destruction of central vision. In other words, the blue light, which has a shorter wavelength and emits more energy compared to other...

The weather will change radically in the coming years. How hot it will be

Researchers have concluded that average temperatures across the globe could be abnormally high between 2018 and 2022. The most important factor underlying this estimation is the multiplication of "extreme heat events" at the surface of the earth and water. The study was conducted before the heat waves that led to the record temperatures that we've endured this year. But the unusually hot weather was correctly predicted by researchers who...

Why are most airplanes painted white?

When it comes to airplanes, white is the primarily preferred color because it reflects the sun's rays and radiation. Thus, since it is painted white, the airplane does not heat up inside as much. Also, this reduces the cost of cooling the cabin. White paint acts as a sort of "sunscreen lotion," according to an aviation expert. Moreover, this color is better preserved over time. Another reason why this color is preferred is the need to protect...

The shortest fly from London to New York will take only two hours

Although commercial planes have shorten the time it takes to go from one place to another, there are people that are still complaining about long flight hours. Boeing could have a solution to the problem. It has introduced details of a new type of Hypersonic Airplane that will be able to cross the distance between New York to London in just 2 hours. The first ultra-fast Mach 5 flight could take place in ten years from now, 2028. The Hypersonic...

It could be possible for plants to create their own fertilizer

A new study led by scientists at Washington University in St. Louis Louis has shown that it is possible to modify plants in order for them to create their own fertilizer. This breakthrough could have a revolutionary effect on agriculture and could help billions of people. The study, led by Himadri Pakrasi and Maitrayee Bhattacharyya-Pakrasi, was recently published in the mBio magazine. The traditional method of creating fertilizer is costly and...

How Novichok nerve agents work

Novichok, the nerve agent that was used on the former former agent Serghei Skripal and his daughter, Julia, is a much stronger chemical weapon than VX, the substance used in the assassination of Kim Jong-nam, the North Korean dictator's step-brother. Unlike other known neurotoxins which are used in the form of vapor or liquid, Novichok is mostly used as an ultra-fine powder. How does this chemical weapon work? Novichok is made up of two...
