     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!

Groundbreaking methane synthesis discovery

An interdisciplinary team of scientists recently published research casting new light on a previously unknown element of the carbon cycle, thanks to data collected from Yellowstone National Park over more than a decade.

The study is the subject of a new paper published this week in the journal Proceedings of the National Academy of Science titled "Aerobic Bacterial Methane Synthesis."

They began studying the microbiology of Yellowstone Lake in 2007. While collecting data to analyze the lake's chemistry and the interaction of various microbes in the lake with the park's underlying thermal features, they noticed something seemed off. They came across some lake water gas chemistries that didn't make  sense.

That discrepancy illustrated what has been termed the "methane paradox." For years, scientists have understood that when microorganisms produce methane, they do it anaerobically, meaning they don't use oxygen. But in the surface waters of the lake where the team was seeing methane, none of those organisms were found.

Methane is a naturally occurring gas made up of carbon and hydrogen atoms. It is the byproduct of a number of biological processes, though human activities like mining coal and refining natural gas also produce methane. It is a greenhouse gas known to be much more potent when trapping heat in the atmosphere than carbon dioxide, which is why many researchers are interested in identifying where in the biosphere it is created and where it goes.

When they did the DNA extraction from the lake water, they couldn't find the anaerobic organisms that are usually responsible for the presence of methane. Instead, they discovered aerobic bacteria were involved, isolating a bacterium called Acidovorax, which then allowed them to begin understanding this process.

Thye used analytical equipment to identify the presence of methylamine and glycine betaine in the lake water, biochemicals the team hypothesized to be key in the process of methane production. To test the theory, they narrowed down which gene the Acidovorax bacteria needed to convert methylamine or glycine betaine into methane.

They could break this down to a basic discovery about methylamine conversion to methane under aerobic conditions

Through a series of microbial experiments and extensive analysis of the wider biological community present in the lake samples, scientists identified a known gene that encodes aspartate aminotransferase, or AAT, that seemed to be catalyzing the methane synthesis.

This is a fundamentally different process from anaerobic methane synthesis

Russia races Tom Cruise and Musk for first movie in space

Six decades after Soviet cosmonaut Yuri Gagarin became the first human to orbit Earth, earning Moscow a key win in the Cold War, Russia is again in a space race with Washington.

This time though the stakes are somewhat glitzier.

On October 5, one of Russia's most celebrated actresses, 36-year-old Yulia Peresild is blasting off to the International Space Station (ISS) with film director Klim Shipenko, 38.

Their mission? Shoot the first film in orbit before the Americans do.

If their plan falls into place, the Russians are expected to beat Mission Impossible star Tom Cruise and Hollywood director Doug Liman, who were first to announce their project together with NASA and Space X, the company of billionaire Elon Musk.

Its plot, which has been kept under wraps by the crew and Russia's space agency, has been revealed by Russian media outlets to feature a doctor dispatched urgently to the ISS to save a cosmonaut.

In preparation for this 21st-century , Peresild has since late May been undergoing  at the Yuri Gagarin Cosmonaut Training Centre in Star City outside Moscow.

Scientists discover a new class of memory cells in the brain

Scientists have long searched in vain for a class of brain cells that could explain the visceral flash of recognition that we feel when we see a very familiar face, like that of our grandmothers. But the proposed "grandmother neuron"—a single cell at the crossroads of sensory perception and memory, capable of prioritizing an important face over the rabble—remained elusive.

Now, new research reveals a class of neurons in the 's temporal pole region that links face perception to long-term memory. It's not quite the apocryphal grandmother neuron—rather than a , it's a population of cells that collectively remembers grandma's face. The findings, published in Science, are the first to explain how our brains inculcate the  of those we hold dear.

Physicists observationally confirm Hawking's black hole theorem for the first time

There are certain rules that even the most extreme objects in the universe must obey. A central law for black holes predicts that the area of their event horizons—the boundary beyond which nothing can ever escape—should never shrink. This law is Hawking's area theorem, named after physicist Stephen Hawking, who derived the theorem in 1971.

Fifty years later, physicists at MIT and elsewhere have now confirmed Hawking's area theorem for the first time, using observations of gravitational waves. Their results appear yesterday (2nd July,2021) in Physical Review Letters.

In the study, the researchers take a closer look at GW150914, the first gravitational wave signal detected by the Laser Interferometer Gravitational-wave Observatory (LIGO), in 2015. The signal was a product of two inspiraling  that generated a new black hole, along with a huge amount of energy that rippled across space-time as gravitational waves.

If Hawking's area theorem holds, then the  area of the new black hole should not be smaller than the total horizon area of its parent black holes. In the new study, the physicists reanalyzed the signal from GW150914 before and after the cosmic collision and found that indeed, the total event horizon area did not decrease after the merger—a result that they report with 95 percent confidence.

Their findings mark the first direct observational confirmation of Hawking's area theorem, which has been proven mathematically but never observed in nature until now. The team plans to test future gravitational-wave signals to see if they might further confirm Hawking's theorem or be a sign of new, law-bending physics.

Solving a murder case with physics

In 2009, famed music producer Phil Spector was found guilty of the murder of actress Lana Clarkson, who was found dead from a single gunshot to her mouth at close range in Spector's California mansion.

During the trial, the attorney argued that Spector couldn't have been the shooter because his white dinner jacket only had a handful blood droplets on it. If he shot Clarkson, the jacket would be covered with blood.

After watching a film about the trial, UIC Distinguished Professor Alexander Yarin was intrigued by the scientific questions it raised. Yarin and his colleagues from Iowa State University—Assistant Professor James Michael and Associate Professor Daniel Attinger— started researching blood spatter, and their recent papers show how Spector could be the shooter and remain relatively free of blood droplets.

The researchers discovered that the gases released from a gun's muzzle brakes escape in a series of turbulent vortex rings, which causes a phenomenon called "blood back spatter"—the blood that travels back toward the shooter—to reverse direction away from the shooter.

At shortrange shooting, the muzzle gasses interfere with the blood back spatter and deflect droplets. Researchers did simulations  and found that there are scenarios where droplets can be turned around completely and land behind the victim. Experiments confirmed that prediction.

In addition, the researchers noted that a shooter could stand in a certain position or at a specific angle and all backward blood spatter would be turned around, keeping the shooter clean.

COVID-19 Makes Lasting Changes to Blood Cells
Why does long COVID last for so long, leaving long-haulers with symptoms that persist for months after initial infection?

New evidence suggests the enduring imprint of COVID-19 could be due to the virus making significant alterations to people's blood – yielding lasting changes to blood cells that are still evident several months after infection is diagnosed.

While the pathology is not yet fully understood, hyper-inflammatory response and coagulation disorders leading to congestions of microvessels are considered to be key drivers of the still increasing death toll.

The results showed that red blood cells (erythrocytes) in COVID-19 patients varied more in size than those from healthy people, and showed signs of stiffness in their physical structure, exhibiting less deformability, which could affect their ability to deliver oxygen through the body.

"The physical properties of erythrocytes are crucial for microcirculatory flow and as such, these changes could impair circulation and promote hypoxemia.

The effect could persist in COVID-19 patients long after the infection is not active anymore; we found that in recovered patients phenotype alterations were not as prominent, but still present. In contrast, the researchers discovered that a form of white blood cells (leukocytes) called lymphocytes showed decreased stiffness in COVID-19 patients, while other white blood cells, known as monocytes, were significantly larger than in cells from the control group.

Meanwhile, neutrophils – another type of white blood cell – showed numerous changes in COVID-19 patients, seen in higher volume, with greater deformation.

the observed changes could arise due to cytoskeletal alterations of immune cells. Mechanical properties of cells can be directly related to the cytoskeleton, an important supportive structure which also determines cellular function."

Scientists discover new type of quasiparticle

Russian scientists have experimentally proved the existence of a new type of quasiparticle - previously unknown excitations of coupled pairs of photons in qubit chains. This discovery could be a step towards disorder-robust quantum metamaterials. The study was published in Physical Review B.

Superconducting qubits are a leading qubit modality today that is currently being pursued by industry and academia for quantum computing applications. However, the performance of quantum computers is largely affected by decoherence that contributes to a qubits extremely short lifespan and causes computational errors. Another major challenge is low controllability of large qubit arrays.

Metamaterial quantum simulators provide an alternative approach to quantum computing, as they do not require a large amount of control electronics. The idea behind this approach is to create artificial matter out of qubits, the physics of which will obey the same equations as for some real matter. Conversely, you can program the simulator in such a way as to embody matter with properties that have not yet been discovered in nature.

Arrays of superconducting qubits are generally described by the Bose-Hubbard model. An interesting feature of the Bose-Hubbard model is the emergence of bound boson pairs (doublons) caused by the strong quantum nonlinearity. The topological physics of doublons has been extensively explored in a series of recent theoretical works. However, the experimental investigation of topological properties of bound photon pairs is still lacking.

the scientists were able to demonstrate for the first time that a new type of quasiparticles - doublon topological excitations - can arise in qubit chains.
