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 July 25, 2020 at 5:35am: Neanderthal gene linked to increased pain sensitivity

People who have inherited nerve-altering mutations from the ancient hominins tend to experience more pain.

Despite their rough and tumble existence, Neanderthals had a biological predisposition to a heightened sense of pain, finds a first-of-its kind genome study published in Current Biology on 23 July . Evolutionary geneticists found that the ancient human relatives carried three mutations in a gene encoding the protein NaV1.7, which conveys painful sensations to the spinal cord and brain. They also showed that in a sample of British people, those who had inherited the Neanderthal version of NaV1.7 tend to experience more pain than others.

Mutations in a gene called SCN9A — which encodes the NaV1.7 protein — stood out because all of the Neanderthals had three mutations that alter the shape of the protein. The mutated version of the gene was found on both sets of chromosomes in all three Neanderthals, hinting that it was common across their populations.NaV1.7 acts in the body’s nerves, where it is involved in controlling whether and to what extent painful signals are transmitted to the spinal cord and brain. “People have described it as a volume knob, setting the gain of the pain in nerve fibres,” says Zeberg. Some people with extremely rare genetic mutations that disable the protein do not feel pain, whereas other changes can predispose people to chronic pain.

Comment by Dr. Krishna Kumari Challa on July 25, 2020 at 4:59am: Coronavirus makes changes that cause cells not to recognize it

With an alarm code, we can enter a building without bells going off. It turns out that the SARS coronavirus 2 (SARS-CoV-2) has the same advantage entering cells. It possesses the code to waltz right in.

How can the coronavirus achieves this?

The scientists resolved the structure of an enzyme called nsp16, which the virus produces and then uses to modify its messenger RNA cap. It's a camouflage. Because of the modifications, which fool the cell, the resulting viral messenger RNA is now considered as part of the cell's own code and not foreign.

How do scientists overcome this?

Deciphering the 3-D structure of nsp16 paves the way for rational design of antiviral drugs for COVID-19 and other emerging coronavirus infections. The drugs, new small molecules, would inhibit nsp16 from making the modifications. The immune system would then pounce on the invading virus, recognizing it as foreign.

bacteria become more deadly in microgravity

Worryingly, research from space flight missions has shown bacteria become more deadly and resilient when exposed to microgravity (when only tiny gravitational forces are present).

In space, bacteria seem to become more resistant to antibiotics and more lethal. They also stay this way for a short time after returning to Earth, compared with bacteria that never left Earth.

Adding to that, bacteria also seem to mutate quicker in space. However, these mutations are predominately for the bacteria to adapt to the new environment – not to become super deadly.

More research is needed to examine whether such adaptations do, in fact, allow the bacteria to cause more disease.

How mosquitoes got their taste for human blood and what it means for the future

Of about 3,500 mosquito species around the world, only a few have taken to specifically targeting people for biting, making them important spreaders of infectious diseases. To predict and help control the spread of those mosquito-borne illnesses, it's important to know where and why, evolutionarily speaking, certain mosquitoes got their taste for biting humans in the first place. Now, researchers reporting in the journal Current Biology on July 23 have identified two major factors: a dry climate and city life. Based on these findings, they predict that increased urbanization in the coming decades will mean even more human-biting mosquitoes in the future. They

found that in their native range of sub-Saharan Africa, they show extremely variable attraction to human hosts, ranging from strong preference for humans to strong preference for non-human animals."

"Mosquitoes living near dense human populations in cities such as Kumasi, Ghana, or Ouagadougou, Burkina Faso, showed increased willingness to bite human hosts," adds Noah Rose, also of Princeton. "But they only evolve a strong preference for human hosts in places with intense dry seasons—in particular, in the Sahel region, where rainfall is concentrated in just a couple months out of the year. We think this is because mosquitoes in these climates are especially dependent on humans and human water storage for their life cycle."

Laughter as a unique biometric signature

The popular view of biometric security often invokes fingerprint readers, iris or retinal scans, and voice-activated systems. However, any unique human characteristic whether the shape of one's ears, the whole face, the pattern of blood vessels in the back of the hand, walking pattern, heart rhythm or even how one types at a keyboard, might be used to provide a secure signature of login. Some traits are easier to analyze than others and some, such as fingerprints, can be spoofed.

Research published in the International Journal of Biometrics has taken an amusing trait to demonstrate how the way a person laughs might be used in biometrics.

people can recognize other people by the unique nature of their laughter, perhaps in an even more obvious way than their voice. Moreover, while many people are adept at impersonating the voices of other people, mimicking someone's laugh is far more difficult. The team has now used statistical analyses of the various audible frequencies present in a person's laugh to create a digital signature for each unique laugh.

Tests on the approach show their prototype recognition algorithm to be 90 percent accurate, which compares very favorably with the 65% accuracy of a conventional Gaussian model. However, combining their algorithm with the Gaussian approach can boost accuracy overall by more than 5 percent.
