WE LOVE SCIENCE HERE BECAUSE IT IS A MANY SPLENDOURED THING

THIS IS A WAR ZONE WHERE SCIENCE FIGHTS WITH NONSENSE AND WINS

“The greatest enemy of knowledge is not ignorance, it is the illusion of knowledge.”

"Being a scientist is a state of mind, not a profession!"

"Science, when it's done right, can yield amazing things".

The Reach of Scientific Research From Labs to Laymen

The aim of science is not only to open a door to infinite knowledge and wisdom but to set a limit to infinite error.

"Knowledge is a Superpower but the irony is you cannot get enough of it with ever increasing data base unless you try to keep up with it constantly and in the right way!" The best education comes from learning from people who know what they are exactly talking about.

Science is this glorious adventure into the unknown, the opportunity to discover things that nobody knew before. And that’s just an experience that’s not to be missed. But it’s also a motivated effort to try to help humankind. And maybe that’s just by increasing human knowledge—because that’s a way to make us a nobler species.

If you are scientifically literate the world looks very different to you.

We do science and science communication not because they are easy but because they are difficult!

“Science is not a subject you studied in school. It’s life. We 're brought into existence by it!"

Comment by Dr. Krishna Kumari Challa on April 30, 2021 at 10:01am: Lightning may be an important source of air-cleaning chemicals

A storm-chasing airplane caught thunderstorms producing extremely high concentrations of two important oxidants

Lightning could play an important role in flushing pollutants out of the atmosphere.

Observations from a storm-chasing airplane reveal that lightning can forge lots of air-cleansing chemicals called oxidants, researchers report online April 29 in Science. Oxidants help clear the air by reacting with contaminants like methane to form molecules that are more water soluble or stickier, allowing them to more easily rain out of Earth’s atmosphere or stick to its surface.

Researchers knew lightning produces nitric oxide, which can lead to the formation of oxidants such as hydroxyl radicals. But no one had seen lightning directly create lots of these oxidants.

--

In May and June 2012, a NASA jet measured two oxidants in storm clouds over Colorado, Oklahoma and Texas. One was the hydroxyl radical, OH. The other was a similar oxidant called the hydroperoxyl radical, HO₂. The combined concentration of OH and HO₂molecules, generated by lightning and other electrified regions of air, reached up to thousands of parts per trillion in some parts of these clouds. The highest concentration of OH previously observed in the atmosphere was a few parts per trillion. The most HO₂observed was about 150 parts per trillion.

Comment by Dr. Krishna Kumari Challa on April 30, 2021 at 8:46am: New law of physics helps humans and robots grasp the friction of touch

Although robotic devices are used in everything from assembly lines to medicine, engineers have a hard time accounting for the friction that occurs when those robots grip objects—particularly in wet environments. Researchers have now discovered a new law of physics that accounts for this type of friction, which should advance a wide range of robotic technologies.

At issue is something called elastohydrodynamic lubrication (EHL) friction, which is the friction that occurs when two solid surfaces come into contact with a thin layer of fluid between them. This would include the friction that occurs when you rub your fingertips together, with the fluid being the thin layer of naturally occurring oil on your skin. But it could also apply to a robotic claw lifting an object that has been coated with oil, or to a surgical device that is being used inside the human body.

One reason friction is important is because it helps us hold things without dropping them.

Understanding friction is intuitive for humans—even when we're handling soapy dishes. But it is extremely difficult to account for EHL friction when developing materials that controls grasping capabilities in robots.

To develop materials that help control EHL friction, engineers would need a framework that can be applied uniformly to a wide variety of patterns, materials and dynamic operating conditions. And that is exactly what the researchers have discovered.

In this context, surface patterns could be anything from the slightly raised surfaces on the tips of our fingers to grooves in the surface of a robotic tool.

The new physical principle makes use of four equations to account for all of the physical forces at play in understanding EHL friction. In the paper, the research team demonstrated the law in three systems: human fingers; a bio-inspired robotic fingertip; and a tool called a tribo-rheometer, which is used to measure frictional forces.

It has obvious applications in the realm of telesurgery, in which surgeons remotely control robotic devices to perform surgical procedures.

Earth has been knocked off its axis over the last 25 years, changing the locations of the north and south poles

Earth's axis - the invisible line around which it spins - is bookended by the north and south poles.
The axis, and thus the poles too, shift depending on how weight is distributed across Earth's surface.
Melting glaciers have changed that distribution enough to knock Earth off its axis, research shows.

Comment by Dr. Krishna Kumari Challa on April 29, 2021 at 9:08am: One dose of COVID vaccine cuts household spread by up to 50%: study

One dose of the Pfizer or AstraZeneca vaccines reduces the chances of someone infected with coronavirus from spreading it to other household members by up to 50 percent, according to a study published Wednesday.

The Public Health England (PHE) research found that those who became infected three weeks after receiving their first jab were between 38 and 49 percent less likely to pass the virus on to their household contacts than those who were unvaccinated.

We already know vaccines save lives and this study is the most comprehensive real-world data showing they also cut transmission of this deadly virus. It further reinforces that vaccines are the best way out of this pandemic as they protect you and they may prevent you from unknowingly infecting someone in your household.

Studies have already shown that being vaccinated reduces the risk of a person developing symptomatic infection in the first place by up to 65 percent, four weeks after one dose.

Comment by Dr. Krishna Kumari Challa on April 28, 2021 at 12:07pm: Farming without disturbing soil could cut agriculture’s climate impact by 30% – new research

agriculture accounts for a staggering 26% of all greenhouse gas emissions. Tractors running on diesel release carbon dioxide (CO₂) from their exhausts. Fertilisers spread on fields produce nitrous oxide. And cattle generate methane from microbes in their guts.

Even tilling the soil – breaking it up with ploughs and other machinery – exposes carbon buried in the soil to oxygen in the air, allowing microbes to convert it to CO₂. Farmers usually do this before sowing crops, but what if they could avoid this step?

In newly published research from farms across the UK, we discovered that an alternative approach called no-till farming, which does not disturb soils and instead involves placing seeds in drilled holes in the earth, could slash greenhouse gas emissions from crop production by nearly a third and increase how much carbon soils can store.

Comment by Dr. Krishna Kumari Challa on April 28, 2021 at 11:13am: Scientists design 'nanotraps' to catch, clear coronavirus

Researchers have designed a completely novel potential treatment for COVID-19: nanoparticles that capture SARS-CoV-2 viruses within the body and then use the body's own immune system to destroy it.

These "Nanotraps" attract the virus by mimicking the target cells the virus infects. When the virus binds to the Nanotraps, the traps then sequester the virus from other cells and target it for destruction by the immune system.

In theory, these Nanotraps could also be used on variants of the virus, leading to a potential new way to inhibit the virus going forward. Though the therapy remains in early stages of testing, the researchers envision it could be administered via a nasal spray as a treatment for COVID-19.

The results were published April 19 in the journal Matter.

Comment by Dr. Krishna Kumari Challa on April 28, 2021 at 11:10am: Researchers discover two-dimensional material using high-pressure technology

An international team of researchers has succeeded for the first time in discovering a previously unknown two-dimensional material by using modern high-pressure technology. The new material, beryllonitrene, consists of regularly arranged nitrogen and beryllium atoms. It has an unusual electronic lattice structure that shows great potential for applications in quantum technology. Its synthesis required a compression pressure that is about one million times higher than the pressure of the Earth's atmosphere. The scientists have presented their discovery in the journal Physical Review Letters.

Researchers have now produced novel compunds composed of nitrogen and beryllium atoms. These are beryllium polynitrides, some of which conform to the monoclinic, others to the triclinic crystal system. The triclinic beryllium polynitrides exhibit one unusual characteristic when the pressure drops. They take on a crystal structure made up of layers. Each layer contains zigzag nitrogen chains connected by beryllium atoms. It can therefore be described as a planar structure consisting of BeN₄ pentagons and Be₂N₄ hexagons. Thus, each layer represents a two-dimensional material, beryllonitrene.
