     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!

'Last resort' antibiotic pops bacteria like balloons

Scientists have revealed how an antibiotic of 'last resort' kills bacteria. The findings may also reveal a potential way to make the antibiotic more powerful.

The antibiotic colistin has become a last resort treatment for infections caused by some of the world's nastiest superbugs. However, despite being discovered over 70 years ago, the process by which this antibiotic kills bacteria has, until now, been something of a mystery.

Now, researchers have revealed that colistin punches holes in bacteria, causing them to pop like balloons.

Colistin was first described in 1947, and is one of the very few antibiotics that is active against many of the most deadly superbugs, including E. coli, which causes potentially lethal infections of the bloodstream, and Pseudomonas aeruginosa and Acinetobacter baumannii, which frequently infect the lungs of people receiving mechanical ventilation in intensive care units.

These superbugs have two 'skins', called membranes. Colistin punctures both membranes, killing the bacteria. However, whilst it was known that colistin damaged the outer membrane by targeting a chemical called lipopolysaccharide (LPS), it was unclear how the inner membranewas pierced.

This work has shown that colistin also targets LPS in the inner membrane, even though there's very little of it present.

Bats found to have innate sense of speed of sound

A pair of researchers with Tel Aviv University's School of Zoology has found that bats have an innate sense of the speed of sound. In their paper published in Proceedings of the National Academy of Sciences, Eran Amichai and Yossi Yovel describe experiments they conducted with both wild and lab raised bats and what they learned from them.

Scientists have known for some time that many species of  use echolocation to determine how far away an object is from them. They send out a signal and then measure its distance by the amount of time that it takes for the signal to bounce back to them. What is not known is whether this ability is something they are born with or if it is learned. To answer that question, the researchers conducted two kinds of experiments—one with bats reared in the lab, the other with captured wild bats.

The first experiment involved raising bats from when they were pups until they were old enough to find food on their own. Each was trained to eat from a certain target placed 130 cm away from a starting perch. Some of the bats were raised in an environment with added helium in the air—helium is thinner than air, thus sound travels faster when passing through it. Each of the bats were then tested under two scenarios. In the first, the bats were tested on their ability to reach the target under normal conditions—they were also timed. In the second scenario, the bats were tested in the same ways as they flew in helium-enriched air.

The researchers found that those flying in helium-enhanced air tended to underestimate the distance to the target—and it did not matter if they were raised in a helium-rich environment or not.

In the second experiment, the researchers caught and trained several wild bats and taught them to eat from the same target as the bats in the first experiment. They then ran the same tests as they did in the first experiment and obtained the same results. The bats flying in helium-enriched air tended to underestimate the distance to the target. The researchers therefore suggest that bats have an innate sense of the speed of sound.

SARS-CoV-2 spike protein alone may cause lung damage

Using a newly developed mouse model of acute lung injury, researchers found that exposure to the SARS-CoV-2 spike protein alone was enough to induce COVID-19-like symptoms including severe inflammation of the lungs.

SARS-CoV-2, the virus that causes COVID-19, is covered in tiny spike proteins. These proteins bind with receptors on our cells, starting a process that allows the virus to release its genetic material  into a healthy cell. The study findings show that the SARS-CoV2 spike protein causes lung injury even without the presence of intact virus.

The researchers found that the genetically modified mice injected with the spike protein exhibited COVID-19-like symptoms that included severe inflammation, an influx of white blood cells into their lungs and evidence of a cytokine storm—an immune response in which the body starts to attack its own cells and tissues rather than just fighting off the virus. The mice that only received saline (control group) remained normal.

And the spike protein in vaccines is not dangerous. Read here why:

'Wolf Packs' of Predatory Bacteria Lurk in Our Soil, And They Play a Crucial Role

You might not have given much thought to predatory bacteria before, but a new study reveals that the behavior of these microorganisms plays a crucial part in the balance of nutrients and carbon capture in soil.

These predatory bacteria – bacteria that eat other bacteria – grow at a faster rate and consume more resources than non-predatory bacteria, and have more of an influence on their surroundings than scientists have previously realized.

In fact, the team behind the study describes the actions of the predatory bacteria as being very much like a wolf pack: They use enzymes and even fang-like filaments to devour other types of bacteria, giving them an outsized influence on their environment.

In long-awaited breakthrough,  scientists harness molecules into single quantum state

 Researchers have big ideas for the potential of quantum technology, from unhackable networks to earthquake sensors. But all these things depend on a major technological feat: being able to build and control systems of quantum particles, which are among the smallest objects in the universe.

That goal is now a step closer with the publication of a new method by  scientists. Published April 28 in Nature, the paper shows how to bring multiple molecules at once into a single quantum state—one of the most important goals in quantum physics.

One of the essential states of matter is called a Bose-Einstein condensate: When a group of particles cooled to nearly absolute zero share a quantum state, the entire group starts behaving as though it were a single atom. It’s a bit like coaxing an entire band to march entirely in step while playing in tune—difficult to achieve, but when it happens, a whole new world of possibilities can open up.

Scientists have been able to do this with atoms for a few decades, but what they’d really like to do is to be able to do it with molecules. Such a breakthrough could serve as the underpinning for many forms of quantum technology.

But because molecules are larger than atoms and have many more moving parts, most attempts to harness them have dissolved into chaos. “Atoms are simple spherical objects, whereas molecules can vibrate, rotate, carry small magnets. Because molecules can do so many different things, it makes them more useful, and at the same time much harder to control.

So the scientists first  cooled the entire system down —down to 10 nanokelvins, a split hair above absolute zero. Then they packed the molecules into a crawl space so that they were pinned flat. Typically, molecules want to move in all directions, and if you allow that, they are much less stable. The researchers confined the molecules so that they are on a 2D surface and can only move in two directions.

The result was a set of virtually identical molecules—lined up with exactly the same orientation, the same vibrational frequency, in the same quantum state.

The scientists described this molecular condensate as like a pristine sheet of new drawing paper for quantum engineering. So far, they’ve been able to link up to a few thousand molecules together in such a state, and are beginning to explore its potential.

Retron Library Recombineering (RLR): New gene editing tool  
Researchers  have created a new gene editing tool called Retron Library Recombineering (RLR) that makes this task easier. RLR generates up to millions of mutations simultaneously, and "barcodes" mutant cells so that the entire pool can be screened at once, enabling massive amounts of data to be easily generated and analyzed. The achievement, which has been accomplished in , is described in a recent paper in PNAS.
RLR enabled scientists to do something that's impossible to do with CRISPR: they randomly chopped up a , turned those genetic fragments into single-stranded DNA in situ, and used them to screen millions of sequences simultaneously.
RLR is a simpler, more flexible gene editing tool that can be used for highly multiplexed experiments, which eliminates the toxicity often observed with CRISPR and improves researchers' ability to explore mutations at the genome level.

Three teams working independently have found evidence that suggests the Z-genome in bacteria-invading viruses is much more widespread than thought. All three of the groups have used a variety of genomic techniques to identify parts of the pathways that lead development of the Z-genome in bacteria-invading viruses known as bacteriophages. The first team was made up of researchers from several institutions in China and one in Singapore, the second with members from several institutions in France; the third was an international effort. All three teams have published their results in the journal Science. Michael Grome and Farren Isaacs with Yale University have also published a Perspectives piece in the same journal issue outlining the work of all three teams.

The Evolution of Bacteria on a “Mega-Plate” Petri Dish

A clock’s accuracy may be tied to the entropy it creates

A clock made from a wiggling membrane produces more disorder as it becomes more accurate

Today’s most advanced clocks keep time with an incredibly precise rhythm. But a new experiment suggests that clocks’ precision comes at a price: entropy.

Entropy, or disorder, is created each time a clock ticks. Now, scientists have measured the entropy generated by a clock that can be run at varying levels of accuracy. The more accurate the clock’s ticks, the more entropy it emitted, physicists report in a paper accepted to Physical Review X.

These cellular clocks help explain why elephants are bigger than mice

Biologists are uncovering how tiny timekeepers in our cells might govern body size, lifespan and ageing.
Time keepers in our cells: Biologists are uncovering how tiny ‘clocks’ in our cells might help govern body size, lifespan and ageing. (Mouse cells seem to run faster than human cells, which tick faster than whale cells.) A wave of research is starting to yield answers for one such timepi.... It helps developing embryos to form repeating body segments, such as vertebrae. Researchers want to understand how differences in developmental pace give rise to organisms with such different bodies and behaviours.
