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!"

Scientists have discovered a powerful new strain of fact-resistant humans who are threatening the ability of Earth to sustain life, a sobering new study reports.
The research, conducted by the University of Minnesota, identifies a virulent strain of humans who are virtually immune to any form of verifiable knowledge, leaving scientists at a loss as to how to combat them.
“These humans appear to have all the faculties necessary to receive and process information. And yet, somehow, they have developed defenses that, for all intents and purposes, have rendered those faculties totally inactive. As facts have multiplied, their defenses against those facts have only grown more powerful.” Davis Logsdon, one of the scientists who contributed to the study, said.
While scientists have no clear understanding of the mechanisms that prevent the fact-resistant humans from absorbing data, they theorize that the strain may have developed the ability to intercept and discard information enroute from the auditory nerve to the brain.
“The normal functions of human consciousness have been completely nullified,” Logsdon said.
While reaffirming the gloomy assessments of the study, Logsdon held out hope that the threat of fact-resistant humans could be mitigated in the future.
“Our research is very preliminary, but it’s possible that they will become more receptive to facts once they are in an environment without food, water, or oxygen,” he said.

A common food additive may make it more difficult to fight the flu.
Vaccinated mice that got food containing the additive, tert-butylhydroquinone (tBHQ), took three days longer to recover from the flu than mice that ate tBHQ-free food. The unpublished result suggests the common additive may make flu vaccines less effective, toxicologist Robert Freeborn of Michigan State University in East Lansing reported April 7 at the 2019 Experimental Biology meeting.
The additive helps stabilize fats and is used as a preservative for a wide variety of foods, including some cooking oils, frozen meat products — especially fish fillets — and processed foods such as crackers, chips and other fried snacks. Food manufacturers aren’t required to put the ingredient on labels, so “it’s hard to know everything it’s in,” says Freeborn.
In separate experiments, unvaccinated mice eating tBHQ in their food had more virus RNA in their lungs than mice that didn’t eat it. The tBHQ eaters also had inflammation and increased mucus production deeper in their lungs than usual, Freeborn and colleagues found.
The researchers don’t know exactly how the additive hampers flu fighting, but it may be because it increases activity of an immune system protein called Nrf2. Increased activity of that protein might reduce the number of virus-fighting immune cells in the mice. That possibility remains to be tested.

Scientists have harnessed liquid metals to turn carbon dioxide back into solid coal, in research that offers an alternative pathway for safely and permanently removing the greenhouse gas from our atmosphere. The new technique can convert CO2 back into carbon at room temperature, a process that's efficient and scalable. A side benefit is that the carbon can hold electrical charge, becoming a supercapacitor, so it could potentially be used as a component in future vehicles.

Hachimoji DNA and RNA : A genetic system with eight building blocks!
DNA and RNA are naturally composed of four nucleotide bases that form hydrogen bonds in order to pair. Hoshika et al. added an additional four synthetic nucleotides to produce an eight-letter genetic code and generate so-called hachimoji DNA. Coupled with an engineered T7 RNA polymerase, this expanded DNA alphabet could be transcribed into RNA. Thus, new forms of DNA that add information density to genetic biopolymers can be generated that may be useful for future synthetic biological applications.
Researchers reported DNA- and RNA-like systems built from eight nucleotide “letters” (hence the name “hachimoji”) that form four orthogonal pairs. These synthetic systems meet the structural requirements needed to support Darwinian evolution, including a polyelectrolyte backbone, predictable thermodynamic stability, and stereoregular building blocks that fit a Schrödinger aperiodic crystal. Measured thermodynamic parameters predict the stability of hachimoji duplexes, allowing hachimoji DNA to increase the information density of natural terran DNA. Three crystal structures show that the synthetic building blocks do not perturb the aperiodic crystal seen in the DNA double helix. Hachimoji DNA was then transcribed to give hachimoji RNA in the form of a functioning fluorescent hachimoji aptamer. These results expand the scope of molecular structures that might support life, including life throughout the cosmos.
It is not common but fathers too can pass mitochondrial DNA to their children!
Fathers in three unrelated families passed mitochondria — tiny energy factories found in cells — on to their children, researchers report.
Scientists have long thought that children inherited mitochondria exclusively from their mothers, since mitochondria from the father’s sperm are usually destroyed after fertilizing the egg. The new research, published online November 26, 2018 in the Proceedings of the National Academy of Sciences, suggests that in rare cases dads can contribute mitochondria too. For now, the consequences of inheriting mitochondria from both parents aren’t known.
Mitochondrial disease researcher Paldeep Atwal spotted the paternal signature after examining DNA from a woman who came to the Mayo Clinic in Jacksonville, Fla. DNA in a cell’s nucleus is inherited equally from both parents and contains all the genetic instructions for building a body. Mitochondria have their own DNA, too, that contains some of the genes needed for building and running the organelles. The woman’s cells weirdly contained two types of mitochondrial DNA, some from mom and some “from elsewhere”.
Thinking the result was a mistake, Atwal and colleagues repeated the test. “The same thing came back the second time, and that’s when the researchers started to get a little bit suspicious”.
The researchers had DNA from both of the woman’s parents, so the team examined the father’s mitochondrial DNA, and found that he was the source of the mystery mitochondria. The woman’s brother also inherited mitochondria from their father.
So Atwal got in touch with Taosheng Huang, a mitochondrial disease expert at Cincinnati Children’s Hospital Medical Center. It turns out that Huang had examined patients from two other families in which fathers had handed mitochondria down to their children. All together, the researchers found 17 people in the three families who inherited 24 percent to 76 percent of their mitochondria from dad.
New technique to do biopsy on living cells
A new set of nanotweezers can extract DNA and other single molecules from a living cell without killing it.
Examining the molecular contents of a single cell has traditionally required killing the cell by bursting it open. But that process provides only a single snapshot of the cell’s molecular makeup at the time of its death. The new nanotweezers, reported online December 3 in Nature Nanotechnology, could enable long-term analysis of what’s going on inside individual cells to better understand how healthy cells work and where diseased cells go wrong.
The nanotweezers comprise a glass rod with a tip less than 100 nanometers across, capped with two carbon-based electrodes. Applying an electric voltage to the tweezers creates a powerful electric field in the immediate vicinity of the electrodes, which can attract and trap biomolecules within about 300 nanometers of the tweezer tip.
Once caught in this 300-nanometer net, molecules are stuck until the tweezer voltage turns off. By positioning the needlelike tweezers with extreme precision, researchers can puncture specific cell compartments and fish for particular molecules.

Scientists are warning that if human beings continue to mine the world’s wildernesses for resources and convert them into cities and farms at the pace of the previous century, the planet’s few remaining wild places could disappear in decades.
Today, more than 77 percent of land on earth, excluding Antarctica, has been modified by human industry, according to a study published recently in the journal Nature, up from just 15 percent a century ago.
The study, led by researchers from the University of Queensland in Australia and the Wildlife Conservation Society in New York, paints the first global picture of the threat to the world’s remaining wildernesses — and the image is bleak.
Wilderness is defined as an area not subject to direct human use.
These areas are the only places on earth that have natural levels of biodiversity, and can continue to sustain plant and animal species on an evolutionary time scale.
Moreover, these spots often act as the world’s lungs, storing carbon dioxide that would otherwise be released into the atmosphere.
Policy experts, take note that even more aggressive action is needed to stop global resource extraction and industrial expansion.
Healthy ecosystems are crucial in their own right for biodiversity and mitigating climate change, but more importantly, said the researchers, they are home for hundreds of millions of indigenous people, who rely on the wilderness to survive and thrive.
