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 May 11, 2021 at 12:23pm: Firefighting chemical found in sea lion and fur seal pups

A chemical that the NSW government has recently partially banned in firefighting has been found in the pups of endangered Australian sea lions and in Australian fur seals.

The new research—part of a long-term health study of seals and sea lions in Australia—identified the chemicals in animals at multiple colonies in Victoria and South Australia from 2017 to 2020.

As well as in pups, the chemicals (Per- and polyfluoroalkyl substances - 'PFAS') were detected in juvenile animals and in an adult male. There was also evidence of transfer of the chemicals from mothers to newborns.

PFAS have been reported to cause cancer, reproductive and developmental defects, endocrine disruption and can compromise immune systems. Exposure can occur through many sources including through contaminated air, soil and water, and common household products containing PFAS. In addition to being used in firefighting foam, they are frequently found in stain repellents, polishes, paints and coatings.

The researchers think the seals and sea lions ingested the chemicals through their fish, crustacean, octopus and squid diets.

Shannon Taylor et al, Per and polyfluoroalkyl substances (PFAS) at high concentrations in neonatal Australian pinnipeds, Science of The Total Environment (2021). DOI: 10.1016/j.scitotenv.2021.147446

Comment by Dr. Krishna Kumari Challa on May 11, 2021 at 12:18pm: Cricket bats should be made from bamboo not willow, study finds

Bamboo cricket bats are stronger, offer a better 'sweet spot' and deliver more energy to the ball than those made from traditional willow, tests conducted by the University of Cambridge show. Bamboo could, the study argues, help cricket to expand faster in poorer parts of the world and make the sport more environmentally friendly.

compared the performance of specially made prototype laminated bamboo cricket bats, the first of their kind, with that of typical willow bats. Their investigations included microscopic analysis, video capture technology, computer modelling, compression testing, measuring how knocking-in improved surface hardness, and testing for vibrations.

The study, published today in The Journal of Sports Engineering and Technology, shows that bamboo is significantly stronger—with a strain at failure more than three times greater—than willow and able to hold much higher loads, meaning that bats made with bamboo could be thinner while remaining as strong as willow. This would help batsmen as lighter blades can be swung faster to transfer more energy to the ball. The researchers also found that bamboo is 22% stiffer than willow which also increases the speed at which the ball leaves the bat.

Ben Tinkler-Davies et al, Replacing willow with bamboo in cricket bats, Proceedings of the Institution of Mechanical Engineers, Part P: Journal of Sports Engineering and Technology (2021). DOI: 10.1177/17543371211016592

--

During manufacture, the surface of cricket bats is compressed to create a hardened layer. When the team compared the effect of this 'knock-in' process on both materials, they found that after 5 hours bamboo's surface hardness had increased to twice that of pressed willow.

Perhaps most excitingly, they found that the sweet-spot on their prototype bamboo blade performed 19% better than that on a traditional willow bat. This sweet-spot was about 20 mm wide and 40 mm long, significantly larger than on a typical willow bat, and better still, was positioned closer to the toe (12.5 cm from the toe at its sweetest point).

This is a batsman's dream. The sweet-spot on a bamboo bat makes it much easier to hit a four off a Yorker for starters, but it's exciting for all kinds of strokes. We'd just need to adjust our technique to make the most of it, and the bat's design requires a little optimisation too.

Comment by Dr. Krishna Kumari Challa on May 11, 2021 at 12:08pm: In the emptiness of space, Voyager 1 detects plasma 'hum'

Voyager 1—one of two sibling NASA spacecraft launched 44 years ago and now the most distant human-made object in space—still works and zooms toward infinity.

The craft has long since zipped past the edge of the solar system through the heliopause—the solar system's border with interstellar space—into the interstellar medium. Now, its instruments have detected the constant drone of interstellar gas (plasma waves), according to Cornell University-led research published in Nature Astronomy.

This work allows scientists to understand how the interstellar medium interacts with the solar wind, Ocker said, and how the protective bubble of the solar system's heliosphere is shaped and modified by the interstellar environment.

After entering interstellar space, the spacecraft's Plasma Wave System detected perturbations in the gas. But, in between those eruptions—caused by our own roiling sun—researchers have uncovered a steady, persistent signature produced by the tenuous near-vacuum of space.

Comment by Dr. Krishna Kumari Challa on May 10, 2021 at 11:49am: In fight against COVID variants some firms target T cell jabs

Getting COVID vaccines into the arms of the world's population is an international priority—but will today's jabs stay effective against virus variants that are spreading across the globe?

It is one of the big questions about the pandemic, with Pfizer chief Albert Bourla recently acknowledging that it is likely a booster will be needed to help extend the protection conferred by its vaccine and ward off new variants.

A recent study presented a mixed picture.

It found that the antibody response of current vaccines could fail against variants. However, a second immune response in the form of killer T cells—which attack already infected cells and not the virus itself—remained largely intact.

Several startups are working on developing shots centred on T cells in hopes of producing a jab that would not only provide protection against new virus strains already on the loose, but also variants that don't yet exist.

Comment by Dr. Krishna Kumari Challa on May 10, 2021 at 11:45am: Largest study to date confirms non-steroidal anti-inflammatory medications do not result in worse COVID-19 outcomes

The use of non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, does not lead to higher rates of death or severe disease in patients who are hospitalised with COVID-19, according to a new observational study of more than 72,000 people in the UK published in The Lancet Rheumatology journal.

NSAIDs are common treatments for acute pain and rheumatological diseases such as rheumatoid arthritis and osteoarthrosis. Early in the pandemic, there was debate on whether the use of such drugs increased the severity of COVID-19, which led to urgent calls for investigations between NSAIDs and COVID-19.

The ISARIC CCP-UK (International Severe Acute Respiratory and emerging Infection Consortium Clinical Characterisation Protocol United Kingdom) study, which is the largest of its kind, provides clear evidence that the continued use of NSAIDs in patients with COVID-19 is safe.

In the study, around a third of patients (30.4%. 1,279 out of 4,211) who had taken NSAIDs prior to hospital admission for COVID-19 died, a rate which was similar (31.3%. 21,256 out of 67,968) in patients who had not taken NSAIDs. In patients with rheumatological disease, the use of NSAIDs did not increase mortality.

Thomas M Drake et al, Non-steroidal anti-inflammatory drug use and outcomes of COVID-19 in the ISARIC Clinical Characterisation Protocol UK cohort: a matched, prospective cohort study, The Lancet Rheumatology (2021). DOI: 10.1016/S2665-9913(21)00104-1
