         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!"

The Mystery of The Platypus Deepens With The Discovery of Its Biofluorescent Fur

Scientists are seeing the  platypus in a whole new light. Under an ultraviolet lamp, this bizarre-looking creature appears even more peculiar than normal, glowing a soft, greenish-blue hue instead of the typical brown we're used to seeing.

Researchers Decipher The Secret Ingredients of Ancient Egyptian Ink

An analysis of 12 ancient papyrus fragments has revealed some surprising details about how the Egyptians mixed their red and black ink – findings which could give us a lot more insight into how the earliest writers managed to get their words down on the page.

Ancient Egyptians were using inks to write at least as far back as 3200 BCE. However, the samples studied in this case were dated to 100-200 CE and originally collected from the famous Tebtunis temple library – the only large-scale institutional library known to have survived from the period.

Using a variety of synchrotron radiation techniques, including the use of high-powered X-rays to analyse microscopic samples, the researchers revealed the elemental, molecular, and structural composition of the inks in unprecedented detail.

The red inks, typically used to highlight headings, instructions, or keywords, were most likely coloured by the natural pigment ochre, the researchers say – traces of iron, aluminium, and hematite point to this being the case.

More intriguing was the discovery of lead-based compounds in both the black and the red inks, without any of the traditional lead-based pigments used for colouring. This suggests the lead was added for technical purposes. Lead-based driers prevent the binder from spreading too much, when ink or paint is applied on the surface of paper or papyrus.

As well as explaining how the ancient Egyptians kept their papyrus smudge-free, it also suggests some pretty specialised ink manufacturing techniques. The fact that the lead was not added as a pigment but as a drier infers that the ink had quite a complex recipe and could not be made by just anyone.

**How to figure out what you don't know

Increasingly, biologists are turning to computational modeling to make sense of complex systems. In neuroscience, researchers are adapting the kinds of algorithms used to forecast the weather or filter spam from your email to seek insight into how the brain's neural networks process information.

Testing various computational models of the nervous system, researchers have found that just because a model can make good predictions about data does not mean it reflects the underlying logic of the biological system it represents. Relying on such models without carefully evaluating their validity could lead to wrong conclusions about how the actual system works.

By building and comparing several models of neural signaling, Engel and Genkin found that good predictive power does not necessarily indicate that a model is a good representation of real neural networks. They found that the best models were instead those that were most consistent across multiple datasets. This approach won't necessarily work for all situations, however, and biologists may need alternative methods of evaluating their models. Most importantly, Genkin said, "We shouldn't take anything for granted. We should check every assumption we have."

Microplastics in groundwater (and our drinking water) present unknown risk

Microplastics (plastics <5mm) and their negative health impacts have been studied in oceans, rivers, and even soils, and scientists are beginning to grapple with the myriad human health impacts their presence might have. One understudied, but critical, link in the cycle is groundwater, which is often a source of drinking water.
While microplastics in groundwater likely affect human health, only a handful of studies have examined the abundance and movement of microplastics in groundwater. This gap means the potential for adverse health effects remains largely unknown.
Microplastics pose multiple physical and chemical risks to the ecosystems where they're present, and those risks are exacerbated by plastics' longevity in natural environments. Since they're plastic, they're very durable which is why plastic is great. But it doesn't degrade easily. Microplastics' ability to linger in their environments for decades or longer likely has cumulative detrimental effects on both the organisms and quality of the ecosystem. Their chemical threat stems largely from their ability to transport harmful compounds on their surfaces; when organisms at the base of the food chain ingest microplastics, they ingest the toxins, too. As larger organisms consume the smaller ones, the toxins can build up (a process called bioaccumulation), eventually resulting in responses like organ dysfunction, genetic mutation, or death. Cave ecosystems are known for being super fragile to begin with. All the cave organisms—salamanders, blind fish—are sensitive, so any contaminants that are introduced could damage those ecosystems.
Groundwater can stay in the same aquifer for tens to hundreds of years, or even longer. Combining that long residence time with plastics' resistance to degradation means that those chemical effects could effectively build up in the water and in any organisms within it, increasing the likelihood of toxic bioaccumulation. Together, these could result in long-term contamination of water sources with poorly-understood health effects and ecosystem damage.
Researchers found that while microplastics do increase in groundwater during a flood event, there's also a second peak in microplastics after the flooding has begun to wane. Their explanation is that there are two sources of microplastics for groundwater: those that are already in the subsurface, and those that are newly delivered from the surface. Finding so much plastic later on in the flood, thinking that it could be coming from the surface... is important to understand the sourcing of microplastics in the groundwater. Knowing where the plastic is coming from could help mitigate future contamination.

Mythbusting: Five common misperceptions surrounding the environmental impacts of single-use plastics

Five misperceptions surrounding the environmental impacts of single-use plastic.

  • Plastic packaging is the largest contributor to a product's environmental impact. In reality, the product inside the package usually has a much greater environmental impact.
  • The environmental impacts of plastics are greater than any other packaging material. Actually, plastic generally has lower overall environmental impacts than single-use glass or metal in most impact categories.
  • Reusable products are always better than single-use plastics. Actually, reusable products have lower environmental impacts only when they are reused enough times to offset the materials and energy used to make them.
  • Recycling and composting should be the highest priority. Truth be told, the environmental benefits associated with recycling and composting tend to be small when compared with efforts to reduce overall consumption.
  • "Zero waste" efforts that eliminate single-use plastics minimize the environmental impacts of an event. In reality, the benefits of diverting waste from the landfill are small. Waste reduction and mindful consumption, including a careful consideration of the types and quantities of products consumed, are far larger factors dictating the environmental impact of an event.

Estimating risk of airborne COVID-19 with mask usage, social distancing

The continued increase in COVID-19 infection around the world has led scientists from many different fields, including biomedicine, epidemiology, virology, fluid dynamics, aerosol physics, and public policy, to study the dynamics of airborne transmission.

Employing basic concepts of  and the known factors in airborne  of diseases, the researchers propose the Contagion Airborne Transmission (CAT) inequality model. While not all factors in the CAT inequality model may be known, it can still be used to assess relative risks, since situational risk is proportional to exposure time.

Using the model, the researchers determined protection from transmission increases with physical distancing in an approximately linear proportion.

If you double your distance, you generally double your protection. This kind of scaling or rule can help inform policy."

The scientists also found even simple cloth masks provide significant protection and could reduce the spread of COVID-19.

 Any physical activity that increases the breathing rate and volume of people will increase the risk of transmission. These findings have important implications for the reopening of schools, gyms, or malls.

Insects Play a Key (And Also Icky Role) in Decomposition by Turning Corpses Into Bones

Life after death: How insects rise from the dead and transform corpses into skeletons

While skeletons are universally considered symbols of death, the process of turning a newly dead animal into a bony skeleton relies on an explosion of life that ushers in the process of decomposition. Much of this transformative process is performed by wriggling, scuttling, scurrying insects.

Through decades of careful observation and experimentation, entomologists have described a five-stage model of decomposition. This model explains how insects, in close collaboration with microorganisms, transform a warm body into a pile of bones while simultaneously recycling carbon, nitrogen, phosphorous, and numerous other nutrients so that other living things may grow and thrive.

Artificial intelligence model detects asymptomatic Covid-19 infections through cellphone-recorded coughs

Asymptomatic people who are infected with Covid-19 exhibit, by definition, no discernible physical symptoms of the disease. They are thus less likely to seek out testing for the virus, and could unknowingly spread the infection to others.

But it seems those who are asymptomatic may not be entirely free of changes wrought by the virus. MIT researchers have now found that people who are asymptomatic may differ from healthy individuals in the way that they cough. These differences are not decipherable to the human ear. But it turns out that they can be picked up by artificial intelligence.

In a paper published recently in the IEEE Journal of Engineering in Medicine and Biology, the team reports on an AI model that distinguishes asymptomatic people from healthy individuals through forced-cough recordings, which people voluntarily submitted through web browsers and devices such as cellphones and laptops.

The researchers trained the model on tens of thousands of samples of coughs, as well as spoken words. When they fed the model new cough recordings, it accurately identified 98.5 percent of coughs from people who were confirmed to have Covid-19, including 100 percent of coughs from asymptomatics — who reported they did not have symptoms but had tested positive for the virus.

The Science of Nerdiness

It’s a neurotransmitter thing

Do you get excited and energized by the possibility of learning something new and complex? Do you get turned on by nuance? Do you get really stimulated by new ideas and imaginative scenarios?

If so, you may have an influx of dopamine in your synapses, but not where we traditionally think of this neurotransmitter flowing.
