         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!"

Bacteria can recover precious metals from electric vehicle batteries

Bioleaching, also called biomining, employs microbes which can oxidise metal as part of their metabolism. It has been widely used in the mining industry, where microorganisms are used to extract valuable metals from ores. More recently, this technique has been used to clean up and recover materials from electronic waste, particularly the printed circuit boards of computers, solar panels, contaminated water and even uranium dumps.

All metals present in EV batteries can be recovered using bioleaching. Bacteria like Acidithiobacillus ferrooxidans and other non-toxic species target and recover the metals individually without the need for high temperatures or toxic chemicals. These purified metals constitute chemical elements, and so can be recycled indefinitely into multiple supply chains.

Scaling up bioleaching involves growing bacteria in incubators at 37°C, often using carbon dioxide. Not a lot of energy is needed, so the process has a much smaller carbon footprint than typical recycling plants, while also contributing less pollution. While reducing EV battery waste, bioleaching facilities mean manufacturers can recover these precious metals locally, and rely less on the few producer countries.

EV batteries are a technology still in their infancy. The reuse of their components should be considered as part of their design. Rather than remaining an afterthought, recycling can become both the beginning and end of an EV battery’s life cycle with bioleaching, producing high-quality raw materials for new batteries at low environmental cost.

Giant spider webs blanket Australian landscape after heavy rainfall

Stunning photographs of vast, ghostly spider webs blanketing the flood-affected region of Gippsland in Victoria have gone viral online, prompting many to muse on the wonder of nature.

But what's going on here? Why do spiders do this after floods and does it happen everywhere?

The answer is: these webs have nothing to do with spiders trying to catch food. Spiders often use silk to move around and in this case are using long strands of web to escape from waterlogged soil.

When these flood events happen, they need evacuate quickly up out of holes they live in underground. They come out en masse and use their silk to help them do that.

You'll often see juvenile spiders let out a long strand of silk which is caught by the wind and lifted up. The web catches onto another object such as a tree and allows the spider to climb up. 

That's how baby spiders (spiderlings!) disperse when they emerge from their egg sacs – it's called ballooning. They have to disperse as quickly as possible because they are highly cannibalistic so they need to move away from each other swiftly and find their own sites to hunt or build their webs.

Physicists bring human-scale object to near standstill, reaching a quantum state

To the human eye, most stationary objects appear to be just that—still, and completely at rest. Yet if we were handed a quantum lens, allowing us to see objects at the scale of individual atoms, what was an apple sitting idly on our desk would appear as a teeming collection of vibrating particles, very much in motion.

In the last few decades, physicists have found ways to super-cool objects so that their atoms are at a near standstill, or in their "motional ." To date, physicists have wrestled small objects such as clouds of millions of atoms, or nanogram-scale objects, into such pure quantum states.

Now for the first time, scientists at MIT and elsewhere have cooled a large, human-scale  to close to its motional ground state. The object isn't tangible in the sense of being situated at one location, but is the combined motion of four separate objects, each weighing about 40 kilograms. The "object" that the researchers cooled has an estimated mass of about 10 kilograms, and comprises about 1x1026, or nearly 1 octillion, atoms.

The researchers took advantage of the ability of the Laser Interfrometer Gravitational-wave Observatory (LIGO) to measure the motion of the masses with extreme precision and super-cool the collective motion of the masses to 77 nanokelvins, just shy of the object's predicted ground state of 10 nanokelvins.

Their results, appearing today in Science, represent the largest object to be cooled to close to its motional ground state. The scientists say they now have a chance to observe the effect of gravity on a massive quantum object.

Giant Rats Are Sniffing Out Landmines and Tuberculosis

These 2-foot giant pouched rats are giving rats a good name. Referred to as 'Hero Rats', they have a superpower that's saving thousands of lives: a powerful nose that can detect unexploded landmines and Tuberculosis. And now, they're being trained to sniff out just about anything, from illegal wildlife trafficking to humans trapped under rubble after a natural disaster.

Genetically engineered nanoparticle delivers dexamethasone directly to inflamed lungs

Nanoengineers at the University of California San Diego have developed immune cell-mimicking nanoparticles that target inflammation in the lungs and deliver drugs directly where they're needed. As a proof of concept, the researchers filled the nanoparticles with the drug dexamethasone and administered them to mice with inflamed lung tissue. Inflammation was completely treated in mice given the nanoparticles, at a drug concentration where standard delivery methods did not have any efficacy.

What's special about these  is that they are coated in a cell membrane that's been genetically engineered to look for and bind to inflamed . They are the latest in the line of so-called cell membrane-coated nanoparticles.

But while these previous cell membranes were naturally derived from the body's , the cell membranes used to coat this dexamethasone-filled nanoparticle were not.

"In this paper, researchers used a genetic engineering approach to edit the  on the cells before we collected the membranes. This significantly advanced our technology by allowing us to precisely overexpress certain functional proteins on the membranes or knockout some undesirable proteins.

New material could remove respiratory droplets from air

Although plexiglass barriers are seemingly everywhere these days—between grocery store lanes, around restaurant tables and towering above office cubicles—they are an imperfect solution to blocking virus transmission.

Instead of capturing virus-laden  and aerosols, plexiglass dividers merely deflect , causing them to bounce away but remain in the air. To enhance the function of these protective barriers, Northwestern University researchers have developed a new transparent material that can capture droplets and aerosols, effectively removing them from air.

The material is a clear, viscous liquid that can be painted onto any surface, including plastic, glass, wood, metal, stainless steel, concrete and textiles. When droplets collide with the coated surface, they stick to it, get absorbed and dry up. The coating also is compatible with antiviral and antimicrobial materials, so sanitizing agents, such as copper, could be added to the formula.

Use of PFAS in cosmetics 'widespread,' new study finds

Many cosmetics sold in the United States and Canada likely contain high levels of per- and polyfluoroalkyl substances (PFAS), a potentially toxic class of chemicals linked to a number of serious health conditions, according to new research from the University of Notre Dame.

Scientists tested more than 200 cosmetics including concealers, foundations, eye and eyebrow products and various lip products. According to the study, 56 percent of foundations and eye products, 48 percent of lip products and 47 percent of mascaras tested were found to contain high levels of fluorine, which is an indicator of PFAS use in the product. The study was recently published in the journal of Environmental Science and Technology Letters.

There's the individual risk—these are products that are applied around the eyes and mouth with the potential for absorption through the skin or at the tear duct, as well as possible inhalation or ingestion. PFAS is a persistent chemcial—when it gets into the bloodstream, it stays there and accumulates. There's also the additional risk of environmental contamination associated with the manufacture and disposal of these products, which could affect many more people.

Studies have linked certain PFAS to kidney cancer, testicular cancer, hypertension, thyroid disease, low birth weight and immunotoxicity in children.

The electron merry-go-round: Researchers find new mechanism for cla...

Photoemission is a property of metals and other materials that emit electrons when struck by light. Electron emission after light absorption was already explained by Albert Einstein. But since this effect is a highly complex process, scientists have still not been able to fully elucidate its details. Prof. Dr. Bernd von Issendorff and his team at the University of Freiburg's Institute of Physics have now succeeded in detecting a previously unknown quantum effect in the angular distributions of photoelectrons from cryogenic mass-selected metal clusters. The angular distributions resemble those of classical particles, a behavior that is surprisingly explainable by the strong electron-electron interaction in these many-electron systems. The researchers published this finding in the current issue of Physical Review Letters.

Scientists discover unreported plant body part

A previously unreported anatomical structure named the 'cantil' has been described in the popular plant model, Arabidopsis thaliana. Scientists reveal that the cantil forms between the stem and flower-bearing stalk when flowering is delayed. Published in the journal Development, this study highlights that there are still discoveries to be made, even in some of the most meticulously studied species, and provides new clues for understanding conditional growth in plants.

Cantils are rare; they only develop under certain conditions that cause the plant to delay flowering, such as short day lengths, and cantils only form at the precise point at which the plant begins to flower.

However, some popular Arabidopsis strains have  that make them incapable of producing cantils at all.
