         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!"

"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!

Scientists encapsulate quantum dots in salt

It's widely known that submerging a pared apple in saltwater prevents oxidation and browning, but did you know that saltwater can also protect fragile quantum dot (QD) materials? A research team led by Prof. Chen Hsueh-Shih of the Department of Materials Science & Engineering at National Tsing Hua University in Taiwan has recently developed the world's first inkjet technique for using saltwater to encapsulate QD materials, which not only resists water and oxygen corrosion, but can also be uniformly printed as a flexible plastic film on a micro LED array for use in high-resolution bendable screens for mobile phones, glasses, etc.

 Shih-Jung Ho et al. Inkjet-Printed Salt-Encapsulated Quantum Dot Film for UV-Based RGB Color-Converted Micro-Light Emitting Diode Displays, ACS Applied Materials & Interfaces (2020). DOI: 10.1021/acsami.0c05646

Coronavirus survives on skin five times longer than flu: study

The coronavirus remains active on human skin for nine hours, researchers have found, in a discovery they said showed the need for frequent hand washing to combat the COVID-19 pandemic.

The findings ‘re published this month in the Clinical Infectious Diseases journal.

The pathogen that causes the flu survives on human skin for about 1.8 hours by comparison. The nine-hour survival of SARS-CoV-2 (the virus strain that causes COVID-19) on human skin may increase the risk of contact transmission in comparison with IAV (influenza A virus), thus accelerating the pandemic.

The research team tested skin collected from autopsy specimens, about one day after death.

Both the coronavirus and the flu virus are inactivated within 15 seconds by applying ethanol, which is used in hand sanitisers.

"The longer survival of SARS-CoV-2 on the skin increases contact-transmission risk; however, hand hygiene can reduce this risk," the study said.

'Classified knots': Researchers create optical framed knots to encode information

In a world first, scientists have been able to create optical framed knots in the laboratory that could potentially be applied in modern technologies. Their work opens the door to new methods of distributing secret cryptographic keys—used to encrypt and decrypt data, ensure secure communication and protect private information.

This is fundamentally important, in particular from a topology-focused perspective, since framed knots provide a platform for topological quantum computations. In addition, they used these non-trivial optical structures as information carriers and developed a security protocol for classical communication where information is encoded within these framed knots.

--

The group tried to achieve the  result  within an optical beam, which presents a high level of difficulty. After a few tries (and knots that looked more like knotted strings), the group came up with what they were looking for: a knotted ribbon structure that is quintessential to framed knots.

In order to add this ribbon, the group relied on beam-shaping techniques manipulating the vectorial nature of light," explained Hugo Larocque. "By modifying the oscillation direction of the light field along an "unframed" optical knot, we were able to assign a frame to the latter by "gluing" together the lines traced out by these oscillating fields.

According to the researchers, structured light beams are being widely exploited for encoding and distributing information.

Climate change likely drove early human species to extinction, mode...

Of the six or more different species of early humans, all belonging to the genus Homo, only we Homo sapiens have managed to survive. Now, a study reported in the journal One Earth on October 15 combining climate modeling and the fossil record in search of clues to what led to all those earlier extinctions of our ancient ancestors suggests that climate change—the inability to adapt to either warming or cooling temperatures—likely played a major role in sealing their fate.

India trusts the scientists the most says a survey

A recent report by the International Science Survey 2019-2020, say more than half of the Indians trust scientists and believe what they’re doing is right. when compared to few other countries around the globe, the degree of trust in India is higher than in many Western countries like the United States, Australia, United Kingdom, and Germany.

The Top 10 countries are given below:

1. India

59% of the respondents in India have “a lot” of trust in scientists to do what is right. 26% had “some” trust”, while 5% “not too much” trust.

2. Australia

48% responded with lot of trust, 34% responded with some trust. 

3. Spain

Similar to Australia 48% Spaniards believe in the goodwill of scientists, while 32% show only some trust and 17% claimed that they had no faith in scientists.

4. Netherlands

47% people have “a lot” of trust in scientists, while 38% had “some” degree of trust. 

5. Sweden

46% Swedes put their faith in scientists, while 44% exhibit some trust.

6. Canada

45% Canadians believe “a lot” in scientists, while 37% had “some” degree of faith.

7. Germany

43% exhibited “a lot” of trust in scientists, while 39% only trusted them to some degree.

8. Czech Republic

42% Czech believe in scientists and their goodwill.

9. United Kingdom

42% trust scientists and what they do, while 37% only trust them to some extent.

10. United States

The world’s No: 1 economy comes iat No 10 position, where 38% have a “lot of” faith in scientists, while 39% only had “some” faith.

whether the ancient healing methods or the Indian scientis community in research labs around the globe and the potential there is some factor which makes us to believe in the scientists.

What fuels the beating heart? Study reveals nutrients used by normal and failing hearts

 A team led by scientists in the Perelman School of Medicine at the University of Pennsylvania has produced a detailed picture of fuel and nutrient use by the human heart. The study, published this week in Science, was the first of its kind, involving the simultaneous sampling of blood from different parts of the circulatory system in dozens of human participants, in order to record the levels of related molecules going into and coming out of the beating heart.

The resulting data have revealed key features of fuel use in the normal heart as well as the failing heart, establishing a new framework for studying the heart in health and disease.

Understanding, at this level of detail, how the heart handles fuel and nutrients should inform the development of future treatments for heart failure and related conditions. Now that we have a clear picture of how the heart fuels itself, we can set our sights on devising ways to improve heart metabolism in heart failure.

For the study, Arany and his team simultaneously sampled blood going into the heart and coming out of the heart in 87 subjects—men and women who were already undergoing a procedure to treat a common condition called atrial fibrillation, but who did not have heart failure. The researchers performed a similar sampling in 23 atrial fibrillation patients who did have heart failure. In all patients, the researchers also sampled blood going into and out of the leg, for comparison.

The team then used state-of-the-art tools to quantify the levels of hundreds of different “metabolites”—molecules involved in fuel use and cell growth—in the blood samples. The main aim was to reveal in detail which metabolites the working heart consumes on balance, and which ones it yields as byproducts.

In all, the researchers detected 277 metabolites reliably in the blood of human participants, and found that for 65 of these, levels going out from the heart were significantly different from levels going in.

The team also made some initial comparisons to highlight what may be unique features of normal heart metabolism. For example, the data indicated that the heart, compared to the legs, relies much more heavily on the uptake, apparently as energy sources, of small organic molecules called fatty acids. At the same time, according to the analysis, the heart releases relatively large amounts of a different class of molecules called amino acids—the building blocks and breakdown products of proteins—hinting that a relatively intense breakdown of protein within the heart is one way the working heart muscle fuels its activity.

A big difference between healthy hearts and failing hearts in the study was that the latter consumed more ketones—molecules the body uses as intermediates in its conversion of stored fats to energy—although the researchers suspect that this disparity may have been due merely to the slower passage of blood through the heart, allowing a greater time for ketone uptake. Compared to normal hearts, the failing hearts also released more amino-acids, suggesting more protein breakdown and turnover.

“Whether this increased protein breakdown in heart failure is adaptive or maladaptive will require further studies

Lipid Droplets Are Intracellular Bacteria-Fighting Machines

The antibacterial function of lipid droplets in cells

Far from being inert fat-storage depots within cells, these lipid-loaded organelles recruit immune proteins and block bacterial growth.

Once thought to be little more than blobs of fat inside eukaryotic cells, lipid droplets may in fact provide a first line of defence against invading pathogens, according to evidence published today . This is the first evidence that there’s a direct [immune] mechanism between lipid droplets and intracellular pathogens

Lipid droplets are a type of organelle that exists in all eukaryotic cells. They are jam-packed full of fats, as the name would suggest, and surrounded by a phospholipid monolayer (as opposed to the classic bilayer membrane surrounding most other organelles). Historically lipid droplets have been thought of as sites for storing excess fats and supplying them when and where needed—for instance, to the mitochondria for energy production. More recently, research has shown that certain cell-invading viruses, bacteria, and parasites exploit these fuel-rich droplets for survival and growth.

But, there’s also evidence that the cell laces lipid droplets with antimicrobial proteins, just as a person might lace cheese with poison to rid their house of invading rodents. Lipid droplets in mouse cells, for example, contain the antiviral compound viperin and a protein involved in activating the immune response against foreign antigens, while those in fruit fly cells contain proteins with antibacterial properties.

The new study, from University of Barcelona cell biologist Albert Pol and colleagues, adds to this evidence, showing definitively that lipid droplets in mammalian cells can contain a wealth of immune proteins and have antibacterial activity against a number of bacterial species.
