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 March 24, 2021 at 8:30am: To produce more food, scientists look to get more mileage out of plant enzymes

Enzymes play essential roles in the cells of every living thing, from bacteria, to plants to people. Some do their jobs a few times and fizzle out. Others can repeat a task hundreds of thousands of times before they quit.

Organisms put a lot of energy into replacing worn out enzymes, energy they could put into other processes. In plants grown for food, fuel, fiber or other purposes, longer lasting enzymes could translate into increased yields.

Andrew D. Hanson el al., "The number of catalytic cycles in an enzyme's lifetime and why it matters to metabolic engineering," PNAS (2021). www.pnas.org/cgi/doi/10.1073/pnas.2023348118

Comment by Dr. Krishna Kumari Challa on March 22, 2021 at 2:15pm: The Sensitivity of Human Fingertips Is Greater Than We Ever Imagined

Skin – the largest organ in the human body – envelops us from head to toe, letting us touch, feel, and interact with the outside world. But there's one part of that organ even more attuned to touch than any other.

A new study has revealed just how receptive the sensory neurons in our fingers are: As it turns out, we can detect touch on the minuscule scale of a single fingerprint ridge.

Sensory neurons attached to receptors are dotted just underneath the skin's surface, allowing us to detect touch, vibration, pressure, pain, and lots more. Our hands alone contain tens of thousands of these neurons, each one with receptors on a small surface area of the skin, called a receptive field.

To map these fields, the researchers strapped down the arms of 12 healthy people and glued their fingernails to plastic holders to really make sure they couldn't move. A machine then wheeled tiny, 0.4 millimeter-wide cones around 7 mm apart across their skin (you can see what that looks like below) and the team recorded each neuron's response using an electrode in the participants' arms.

Specifically, they were mapping the more sensitive zones – known as subfields – within these receptive fields.

By calculating the sensory neuron detection areas and mapping them onto the fingerprint, the team found that the detection area's width was equivalent to the width of one fingerprint ridge.

These subfields also didn't move when the machine wheeled the dots faster or slower, or changed directions, suggesting that these sensitive areas are anchored to the fingerprint ridges themselves.

"We report that the sensitivity of the subfield arrangement for both neuron types on average corresponds to a spatial period of ~0.4 mm and provide evidence that a subfield's spatial selectivity arises because its associated receptor organ measures mechanical events limited to a single papillary ridge," the researchers write in their new paper.

Comment by Dr. Krishna Kumari Challa on March 22, 2021 at 2:09pm: Scientists Just Demonstrated How These 'Spiders' Might Form on Mars

We may not have detected life on Mars, but we have found 'spiders'... of a sort.

They're called araneiforms: dark, spider-like systems of branching, fractal troughs found only in the southern polar regions of the red planet. There's nothing like them on Earth, or any other planet in the Solar System.

That makes it tricky to understand what creates them, but scientists have just obtained the first physical evidence that supports the most popular model, known as Kieffer's hypothesis. According to this idea, the spider-like forms are shaped by the direct sublimation of frozen carbon dioxide (CO₂).

"This research presents the first set of empirical evidence for a surface process that is thought to modify the polar landscape on Mars

A fast, low-cost technique to see and count viruses or proteins from a sample in real time, without any chemicals or dyes, could underpin a new class of devices for rapid diagnostics and viral load monitoring, including HIV and the virus that causes COVID-19. Researchers at the University of Illinois Urbana-Champaign described the technique, called Photonic Resonator Interferometric Scattering Microscopy, or PRISM, in the journal Nature Communications.

Researchers have developed a new form of microscopy that amplifies the interaction between light and biological materials. One can use it for very rapid and sensitive forms of diagnostic testing, and also as a very powerful tool for understanding biological processes at the scale of individual items, like counting individual proteins or recording individual protein interactions.

Comment by Dr. Krishna Kumari Challa on March 22, 2021 at 6:38am: Carbon pawprint: is man's best friend the planet's enemy?

Is your adorable puppy as bad for the planet as a gas-guzzling SUV?

While the precise carbon pawprint of our pets is the source of scientific debate, one thing is becoming increasingly clear: lovable, they may be, cats and dogs have an impact on the planet.

No doubt, they bring a lot of good to people, both working animals and companion animals. But they mostly eat meat.

However, some argue that because most pet foods are based on secondary products from the human food industry, especially the ingredients that are animal-based, the environmental costs of those ingredients are not the same as those being consumed by humans.

Yet in some countries meat is reared specifically for animal consumption. As with humans—animal carbon footprints "depend on where you live in the world".

But scientists can agree on at least one thing: a large dog, logically, eats more than a small cat and therefore has a bigger environmental impact. It si not possible to make a dog fully vegetarian.

So what can the environmentally conscious animal lovers out there do to mitigate the damage caused by their furry friends?

Experts suggest considering other species of animals to have as pets, such as hamsters or birds. But if you don't want to have an ecological pawprint, don't have a pet at all. Let them live in wilderness using natural resources and bound by natural laws.

But one environmental impact from outdoor cats can't be avoided. A massacre all around your home: dead birds, shrews, lizards...

One solution for animals and the planet would be to cut down or diversify the protein in their diet.

Several dried food producers already use insects in their kibble, although there is still debate over the environmental merits of various animal foods and their production.

Comment by Dr. Krishna Kumari Challa on March 20, 2021 at 11:19am: Study shows stronger brain activity after writing on paper than on tablet or smartphone

Unique, complex information in analog methods likely gives brain more details to trigger memory.

A study of Japanese university students and recent graduates has revealed that writing on physical paper can lead to more brain activity when remembering the information an hour later. Researchers say that the unique, complex, spatial and tactile information associated with writing by hand on physical paper is likely what leads to improved memory.

"Actually, paper is more advanced and useful compared to electronic documents because paper contains more one-of-a-kind information for stronger memory recall.

Contrary to the popular belief that digital tools increase efficiency, volunteers who used paper completed the note-taking task about 25% faster than those who used digital tablets or smartphones.

Comment by Dr. Krishna Kumari Challa on March 20, 2021 at 11:01am: Teamwork makes light shine ever brighter

If youre looking for one technique to maximize photon output from plasmons, stop. It takes two to wrangle. Rice University physicists came across a phenomenon that boosts the light from a nanoscale device more than 1,000 times greater than they anticipated. When looking at light coming from a plasmonic junction, a microscopic gap between two gold nanowires, there are conditions in which applying optical or electrical energy individually prompted only a modest amount of light emission. Applying both together, however, caused a burst of light that far exceeded the output under either individual stimulus.
