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!"

Comment by Dr. Krishna Kumari Challa on June 19, 2020 at 6:37am: Glaciers may record the story of the coronavirus pandemic for future generations

The coronavirus pandemic will be remembered for decades to come through history books, oral narratives and an abundance of personal protective equipment. However, the glaciers of the Himalayas, the Alps, Patagonia and other regions may also hold the story of this time. Among the layers of ice lay records of many things—volcanic eruptions, other pandemics, ancient civilizations, and anthropogenic climate change. The precipitous decline in air pollutants, the reduction of greenhouse gas emissions, and changes in atmospheric composition during the coronavirus pandemic might eventually be observed in glacial ice.

Atmospheric wind currents carry gases, particulates, and other substances to glaciers. When snow containing these particulates and dissolved chemicals from the air collects on glaciers, it traps the transported substances. Air bubbles—samples of the gases in the atmosphere (e.g. long-lived gases like carbon dioxide)—also form. Over months and years as more snow accumulates, older layers of snow and gas are compressed and sealed—preserving samples of atmospheric conditions at the time of precipitation. By drilling below the surface, scientists extract ice cores which contain these substances. The chemical composition of the ice and air trapped within it serves as a proxy for researchers to analyze atmospheric changes over time.

The atmospheric changes caused by the COVID-19 lockdowns could similarly be recorded in glacial ice for future scientists to analyze. With planes, trains, and cars coming to a grinding halt, polluting factories stopping their work, the effects of a drastic drop in transportation and work has already been seen in reductions in nitrogen dioxide emissions. In the atmosphere, nitrogen oxides transform to nitrates, which are deposited on surfaces such as glaciers where they are preserved. Scientists think that human activity dominates NOx emissions so we might be able to see a signal of that potentially in glaciers and ice cores. And because we have seen a decrease in concentrations in the atmosphere at least in cities, we might expect to see a decrease in nitrate concentrations in glaciers.

Future paleoclimatologist can study glaciers and find out about our agony during the pandemic!

Comment by Dr. Krishna Kumari Challa on June 19, 2020 at 6:22am: Earth’s rock-solid connections between Canada and Australia contain clues about the origin of life

The rocks at the surface of the modern Earth are broadly divided into two types: felsic and mafic. Felsic rocks are generally relatively low density—for a rock—and light in color because they are made from whitish minerals rich in silicon and aluminum. Half Dome in California is made of granite that is a felsic rock. Mafic rocks, in contrast, are relatively high in density and dark in color because they contain minerals rich in iron and magnesium; Giants Causeway in Northern Ireland is made of basalt, which is a mafic rock.

The difference in density between felsic and mafic rocks means that felsic rocks are more buoyant, and therefore sit at higher elevations above the Earth's mantle (the layer inside the Earth between the crust and the core). For this reason, felsic rocks make up Earth's continents whereas the lower elevation....

The mechanisms that separated the rocks at Earth's surface into these two groups may have also created the environment needed for life to flourish 4.3 billion years ago, very early in the history of Earth.

The separation into these two rock types is the result of plate tectonics: where the tectonic plates separate and move apart, the rocks below become depressurized, melt and fill in the gap between them, like the Mid-Atlantic Ridge). The rock that fills the gap between the plates is mafic.

When one plate slides below another, fluids released from the lower plate cause melting in the mantle. These melts have to pass through the upper plate to reach the surface. On their way to the surface, they undergo a series of processes called fractional crystalization, which can change mafic melts into felsic melts.

When this separation happened is a matter of great debate in the Earth sciences because it may allow us to determine when the Earth became habitable for life. Many Earth scientists believe that the weathering of continental crust may have provided the nutrients for life to thrive; identifying when the first continents formed indicates when this may have occurred.

The exact mechanism is important for understanding the history and evolution of Earth, and may help understand the processes that could be occurring on other planets.

Comment by Dr. Krishna Kumari Challa on June 19, 2020 at 6:13am: Studying the Neandertal DNA found in modern humans using stem cells and organoids

Studies have found that about 2% of the genomes of modern humans from outside Africa are composed of Neandertal DNA. This archaic DNA is a result of mating between the two groups tens of thousands of years ago.

In the new study, the team used resources from the Human Induced Pluripotent Stem Cells Initiative (HipSci), an international consortium that provides data and cell lines for research. Nearly all of the data and cell lines in HipSci are from people of UK and Northern European descent. The researchers analyzed this cell line resource for its Neandertal DNA content and annotated functional Neandertal variants for each of the cell lines.

"Some Neandertal alleles have relatively high frequency in this population," Camp explains. "Because of that, this iPSC resource contains certain genes that are homozygous for Neandertal alleles, including genes associated with skin and hair color that are highly prevalent in Europeans."

Camp's team used five cell lines to generate brain organoids and generated single-cell RNA sequencing data to analyze their cell composition. They showed that this transcriptomic data could be used to track Neandertal-derived RNA across developmental processes

Comment by Dr. Krishna Kumari Challa on June 19, 2020 at 6:05am: Do you know these things about thorns?

The thorns help protect against hungry animals that like to munch on the plants.

Where do they come from?

This is for non-botanists: Many plants have sharp, spiky armour that can be classified as thorns, prickles or spines.

Now get surprised: Rose bushes do not have thorns; they have prickles, as do raspberry and blackberry bushes. Prickles are like thick hairs on your arm, and in roses and other prickly plants, the prickles grow from their epidermis, or "skin".

Other plants, including cacti, have spines, another type of sharp, pointy weaponry that forms instead of leaves. Thorns arise from shoots in plants such as bougainvillea, hawthorn and citrus.

Scientists have found that in citrus plants, thorns arise from the plants' stem cell populations. Unlike typical stem cells in animals or plants, which continue to divide, thorn stem cells undergo a programmed arrest. The scientists found that two regulators of stem cell production, TI1 and TI2, gradually shut down stem cell activity in the developing thorn, so that it tapers off until nothing is left but the sharp pointy end.

When the researchers genetically eliminated the two regulators, stem cell activity continued, and instead of thorns, the citrus plants produced new branches.

The insight could lead to orchards of orange trees with more fruit-bearing branches—ones that pose less danger to labourers who pick the fruit.
