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 July 7, 2020 at 6:19am: Dying stars breathe life into Earth: study

As dying stars take their final few breaths of life, they gently sprinkle their ashes into the cosmos through the magnificent planetary nebulae. These ashes, spread via stellar winds, are enriched with many different chemical elements, including carbon.

Findings from a study published today in Nature Astronomy show that the final breaths of these dying stars, called white dwarfs, shed light on carbon's origin in the Milky Way.

"The findings pose new, stringent constraints on how and when carbon was produced by stars of our galaxy, ending up within the raw material from which the Sun and its planetary system were formed 4.6 billion years ago.

The origin of carbon, an element essential to life on Earth, in the Milky Way galaxy is still debated among astrophysicists: some are in favor of low-mass stars that blew off their carbon-rich envelopes by stellar winds became white dwarfs, and others place the major site of carbon's synthesis in the winds of massive stars that eventually exploded as supernovae.

Using data from the Keck Observatory near the summit of Mauna Kea volcano in Hawaii collected between August and September 2018, the researchers analyzed white dwarfs belonging to the Milky Way's open star clusters. Open star clusters are groups of up to a few thousand stars held together by mutual gravitational attraction.

From this analysis, the research team measured the white dwarfs' masses, and using the theory of stellar evolution, also calculated their masses at birth.

The connection between the birth masses to the final white dwarf masses is called the initial-final mass relation, a fundamental diagnostic in astrophysics that contains the entire life cycles of stars. Previous research always found an increasing linear relationship: the more massive the star at birth, the more massive the white dwarf left at its death.

But when Cummings and his colleagues calculated the initial-final mass relation, they were shocked to find that the white dwarfs from this group of open clusters had larger masses than astrophysicists previously believed. This discovery, they realized, broke the linear trend other studies always found. In other words, stars born roughly 1 billion years ago in the Milky Way didn't produce white dwarfs of about 0.60-0.65 solar masses, as it was commonly thought, but they died leaving behind more massive remnants of about 0.7—0.75 solar masses.

The researchers say that this kink in the trend explains how carbon from low-mass stars made its way into the Milky Way. In the last phases of their lives, stars twice as massive as the Milky Way's Sun produced new carbon atoms in their hot interiors, transported them to the surface and finally spread them into the surrounding interstellar environment through gentle stellar winds.

Carbon star formation as seen through the non-monotonic initial–final mass relation, Nature Astronomy (2020). DOI: 10.1038/s41550-020-1132-1 , www.nature.com/articles/s41550-020-1132-1

Comment by Dr. Krishna Kumari Challa on July 7, 2020 at 6:11am: Group genomics drive aggression in honey bees

Researchers often study the genomes of individual organisms to try to tease out the relationship between genes and behavior. A new study of Africanized honey bees reveals, however, that the genetic inheritance of individual bees has little influence on their propensity for aggression. Instead, the genomic traits of the hive as a whole are strongly associated with how fiercely its soldiers attack.

Comment by Dr. Krishna Kumari Challa on July 6, 2020 at 8:31am: Declining eyesight improved by looking at deep red light

Declining eyesight can be improved by looking at deep red light: Staring at a deep red light for three minutes a day can significantly improve declining eyesight, finds a new study, the first of its kind in humans. This finding could signal the dawn of new affordable home-based eye therapies, helping the millions of people globally with naturally declining vision.

As you age your visual system declines significantly, particularly once over 40.

Your retinal sensitivity and your colour vision are both gradually undermined, and with an aging population, this is an increasingly important issue. To try to stem or reverse this decline, we sought to reboot the retina's aging cells with short bursts of longwave light.

In humans around 40 years-old, cells in the eye's retina begin to age, and the pace of this aging is caused, in part, when the cell's mitochondria, whose role is to produce energy (known as ATP) and boost cell function, also start to decline.

Mitochondrial density is greatest in the retina's photoreceptor cells, which have high energy demands. As a result, the retina ages faster than other organs, with a 70% ATP reduction over life, causing a significant decline in photoreceptor function as they lack the energy to perform their normal role.

Researchers built on their previous findings in mice, bumblebees and fruit flies, which all found significant improvements in the function of the retina's photoreceptors when their eyes were exposed to 670 nanometre (long wavelength) deep red light.

Mitochondria have specific light absorbance characteristics influencing their performance: longer wavelengths spanning 650 to 1000nm are absorbed and improve mitochondrial performance to increase energy production.

Researchers found the 670nm light had no impact in younger individuals, but in those around 40 years and over, significant improvements were obtained.

Cone color contrast sensitivity (the ability to detect colors) improved by up to 20% in some people aged around 40 and over. Improvements were more significant in the blue part of the color spectrum that is more vulnerable in aging.

Rod sensitivity (the ability to see in low light) also improved significantly in those aged around 40 and over, though less than color contrast.

Comment by Dr. Krishna Kumari Challa on July 4, 2020 at 10:32am: Scientists have engineered a self-destruct button in bacteria: we’re tricking pathogenic microbes into killing themselves.

Sneaky molecular biology tricks bacteria into killing themselves, in place of antibiotics. Researchers have published a new kind of molecular trickery that selectively kills harmful and antibiotic-resistant bacteria without traditional antibiotics. V. cholerae, which causes cholera encodes multiple toxins in its genome. Bacterial toxins inhibit vital processes like DNA replication or cell division. Typically, anti-toxins – that the bacteria also produce themselves – protect bacteria from poisoning themselves. Stress activates the toxins, often leading to cell death. Although exactly why bacteria maintain deadly toxin genes is still puzzling, we know that artificially activating the toxins provides a route to kill bacteria.

The researchers manipulated the DNA sequences of V. cholerae to create a code for production of the toxin in specific kinds of bacteria. The specificity of bacterial gene regulation ensures that only certain bacteria can interpret this code. Bad news for the ones that can: they end up triggering their own death.

Scientists say that initiating what can be thought of as bacterial suicide by modifying their DNA might be the next workable solution to antibiotic resistance.
