     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!

Researchers at Brazil's space institute discover why lightning branches and flickers

Researchers have recorded for the first time the formation and branching of luminous structures by lightning strikes.

Analyzing images captured by a super slow motion camera, they discovered why  strikes bifurcate and sometimes then form luminous structures interpreted by the human eye as flickers.

The researchers used ultra high speed digital video cameras to record more than 200 upward flashes during summer thunderstorms in São Paulo City (Brazil) and Rapid City, South Dakota (USA) between 2008 and 2019. Upward lightning strikes start from the top of a tall building or other ground-based structure and propagate upward to the overlying cloud.

The upward flashes they recorded were triggered by positively charged cloud-to-ground lightning discharges, which are much more common, as described by the same INPE research group in a previous study.

"Upward lightning originates at the top of a tower or the lightning conductor on a skyscraper, for example, when the storm's electrical field is disturbed by a cloud-to-ground discharge as far away as 60 kilometers.

Although the study conditions were very similar in Brazil and the US, luminous structures were observed in only three upward flashes, recorded in the US. These were formed by a positive leader discharge propagating toward the cloud base.

"The advantage of recording images of upward lightning is that they let us see the entire trajectory of these positive leaders from ground to cloud base. Once inside the cloud, they can no longer be seen.

The researchers found that a low-luminosity discharge with a structure resembling a paintbrush sometimes forms at the tip of the positive leader. It was observed that this discharge, often referred to as a corona brush, may change direction, split in two, and define the path of the lightning flash and how it branches.

When an upward flash branches successfully, it may proceed to the left or right. When branching fails, the corona brush may give rise to very short segments as bright as the leader itself. These segments first appear milliseconds after the corona brush splits, and pulsate as the leader propagates upward toward the cloud base, the videos show.

The flickers are recurring failed attempts to start a branch, the flickers may explain why multiple lightning discharges are frequent, but more studies are needed to verify this theory.

Researchers identify nanoparticles that could deliver therapeutic mRNA before birth

Researchers have identified ionizable lipid nanoparticles that could be used to deliver mRNA as part of fetal therapy. The proof-of-concept study, published today in Science Advances, engineered and screened a number of lipid nanoparticle formulations for targeting mouse fetal organs and has laid the groundwork for testing potential therapies to treat genetic diseases before birth.

This is an important first step in identifying nonviral mediated approaches for delivering cutting-edge therapies before birth.

These   may provide a platform for in utero mRNA delivery, which would be used in therapies like fetal protein replacement and gene editing.

Having identified the lipid nanoparticles that were able to accumulate within fetal livers, lungs, and intestines with the highest efficiency and safety, the researchers also tested therapeutic potential of those designs by using them to deliver erythropoietin (EPO) mRNA, as the EPO protein is easily trackable. They found that EPO mRNA delivery to liver cells in mouse fetuses resulted in elevated levels of EPO protein in the fetal circulation, providing a model for protein replacement therapy via the liver using these lipid nanoparticles.

Grey camouflage 'better than zebra stripes'

Dull, featureless camouflage provides better protection from predators than zebra stripes, according to a new study.

Biologists explaining the existence of such stripes have proposed the "motion dazzle hypothesis", which suggests that high-contrast patterns can make it difficult for predators to track a .

University of Exeter scientists tested this using a touch-screen game called Dazzle Bug in which visitors to Cornwall's Eden Project had to catch a moving rectangular "bug".

Bug patterns were programmed to "evolve" to find the best camouflage strategy.

"Surprisingly, targets evolved to lose patterns and instead match their backgrounds. 

The new study results indicate that low-contrast, featureless targets were hardest to catch when in motion. These findings provide the clearest evidence to date against the motion dazzle hypothesis and suggest that protection in motion may rely on completely different mechanisms to those previously assumed.

Could we harness energy from black holes?

A remarkable prediction of Einstein's theory of general relativity—the theory that connects space, time, and gravity—is that rotating black holes have enormous amounts of energy available to be tapped.

For the last 50 years, scientists have tried to come up with methods to unleash this power. Nobel physicist Roger Penrose theorized that a particle disintegration could draw energy from a black hole; Stephen Hawking proposed that  could release energy through quantum mechanical emission; while Roger Blandford and Roman Znajek suggested electromagnetic torque as a main agent of energy extraction.

Now, in a study published in the journal Physical Review D, physicists Luca Comisso from Columbia University and Felipe Asenjo from Universidad Adolfo Ibanez in Chile, found a new way to extract energy from black holes by breaking and rejoining  lines near the , the point from which nothing, not even light, can escape the black hole's gravitational pull.

"Black holes are commonly surrounded by a hot 'soup' of  particles that carry a magnetic field. This new theory theory shows that when  disconnect and reconnect, in just the right way, they can accelerate plasma particles to negative energies and large amounts of black hole energy can be extracted.

This finding could allow astronomers to better estimate the spin of black holes, drive black hole energy emissions, and might even provide a source of energy for the needs of an advanced civilization.

Fish-inspired robots coordinate movements without any outside control

Schools of fish exhibit complex, synchronized behaviors that help them find food, migrate and evade predators. No one fish or team of fish coordinates these movements nor do fish communicate with each other about what to do next. Rather, these collective behaviors emerge from so-called implicit coordination—individual fish making decisions based on what they see their neighbors doing.

This type of decentralized, autonomous self-organization and coordination has long fascinated scientists, especially in the field of robotics.

Now, a team of researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and the Wyss Institute for Biologically Inspired Engineering have developed fish-inspired robots that can synchronize their movements like a real school of fish, without any external control. It is the first time researchers have demonstrated complex 3-D collective behaviours with implicit coordination in underwater robots.

Melting icebergs key to sequence of an ice age, scientists find

Scientists claim to have found the 'missing link' in the process that leads to an ice age on Earth.

Melting icebergs in the Antarctic are the key, say the team from Cardiff University, triggering a series of chain reactions that plunges Earth into a prolonged period of cold temperatures.

The findings have been published today in Nature from an international consortium of scientists from universities around the world.

It has long been known that ice age cycles are paced by periodic changes to Earth's orbit of the sun, which subsequently changes the amount of solar radiation that reaches the Earth's surface.

However, up until now it has been a mystery as to how small variations in solar energy can trigger such dramatic shifts in the climate on Earth.

In their study, the team propose that when the orbit of Earth around the sun is just right, Antarctic icebergs begin to melt further and further away from Antarctica, shifting huge volumes of freshwater away from the Southern Ocean and into the Atlantic Ocean.

As the Southern Ocean gets saltier and the North Atlantic gets fresher, large-scale ocean circulation patterns begin to dramatically change, pulling CO2 out of the atmosphere and reducing the so-called greenhouse effect.

This in turn pushes the Earth into ice age conditions.

As part of their study the scientists used multiple techniques to reconstruct past climate conditions, which included identifying tiny fragments of Antarctic rock dropped in the open ocean by melting icebergs.

Study Just Identified 6 Distinct Types of Prediabetes

People with prediabetes have a higher than normal blood sugar level, and sometimes – but not always – go on to develop type 2 diabetes. Doctors should now be able to better manage that risk, thanks to a study identifying six different subtypes of prediabetes.

In an analysis covering 25 years of data and 899 individuals, researchers were able to categorise these six subtypes through a series of shared biomarkers, including glucose levels, liver fat, body fat distribution, blood lipid levels, and genetic risk.

The six subtypes (or "clusters") carry different levels of risk when it comes to developing type 2 diabetes, and that should help health professionals in tailoring treatments to match, as well as managing prediabetes and the secondary issues that come with it.

Clusters 1, 2 and 4 represent a low diabetes risk: they include participants who aren't overweight, or who are overweight but have a relatively healthy metabolism. Clusters 3, 5 and 6, meanwhile, are linked to an increased risk of diabetes and secondary diseases. 

Those in cluster 3 produce too little insulin naturally, as well as showing other biomarkers such as higher intima-media thickness (IMT) in their arteries. Cluster 5 includes people more resistant to the effects of insulin and also with higher amounts of liver fat.

Those in cluster 6 have higher levels of particular types of body fat (visceral and renal sinus). While these individuals have a lower risk of developing diabetes compared with clusters 3 and 5, there is a higher mortality risk and more chance of kidney malfunction in this group.

Mathematics explains how giant whirlpools form in developing egg cells

Egg cells are among the largest cells in the animal kingdom. If moved only by the random jostlings of water molecules, a protein could take hours or even days to drift from one side of a forming egg cell to the other. Luckily, nature has developed a faster way: cell-spanning whirlpools in the immature egg cells of animals such as mice, zebrafish and fruit flies. These vortices enable cross-cell commutes that take just a fraction of the time. But until now, scientists didn't know how these crucial flows formed.

Scientists Discover a New Type of Chemical Bond, And It's Surprisingly Strong

It's like the hydrogen bonds found in water, but way stronger.

Scientists have recently discovered a totally new type of chemical bond – and it's way stronger than it has any right to be.

The new type of bond shows that the divide between powerful covalent bonds, which bind molecules together, and weak hydrogen bonds, which form between molecules and can be broken by something as simple as stirring salt into a glass of water.

Ionic bonds link metals and non-metals to form salts. Strong covalent bonds bind together molecules like carbon dioxide and water. Far weaker hydrogen bonds form because of an electrostatic type of attraction between hydrogen and a more negatively charged atom or molecule, for instance causing water molecules to attract one another and form droplets or crystalline ice.

Ionic, covalent, and hydrogen bonds are all relatively stable; they tend to last for extended periods of time and have effects are easily observable.

But researchers have long known that during a chemical reaction, as chemical bonds are forming or breaking, the story is more complicated and involves "intermediate states" that may exist for tiny fractions of a second and are more difficult to observe. 

In the new study, the researchers managed to keep these intermediate states going for long enough to make a detailed examination. What they found was a hydrogen bond with the strength of a covalent bond, binding atoms together into something resembling a molecule.

Washing your clothes can create microplastic pollution

Households in Europe and North America are flooding the oceans with plastic pollution simply by washing their clothes, scientists said Tuesday after research found the majority of microplastics in Arctic seawater were polyester fibres.

Plastic particles have infiltrated even the most remote and seemingly-pristine regions of the planet.

These tiny fragments have been discovered inside fish in the deepest recesses of the —the Mariana Trench—peppering Arctic sea ice and blanketing the snows on the Pyrenees mountains between France and Spain.

But questions remain over exactly where this  contamination is coming from.

In the new study by the Ocean Wise conservation group and Canada's Department of Fisheries and Oceans, researchers sampled seawater from across the Arctic and found  made up around 92 percent of microplastic pollution.

Of this, around 73 percent was found to be polyester, resembling the dimensions and chemical identities of synthetic textiles—particularly clothing.

"The striking conclusion here is that we now have strong evidence that homes in Europe and North America are directly polluting the Arctic with fibres from laundry (via wastewater discharge)

 Pervasive distribution of polyester fibres in the Arctic Ocean is driven by Atlantic inputs, Nature CommunicationsDOI: 10.1038/s41467-020-20347-1 ,
