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 17, 2020 at 8:27am: How deadly is the coronavirus? Scientists are close to an answer

Public-health researchers use the infection fatality rate to gauge how to respond to a new disease, but it’s tricky to calculate.

Researchers use a metric called infection fatality rate (IFR) to calculate how deadly a new disease is. It is the proportion of infected people who will die as a result, including those who don’t get tested or show symptoms.

“The IFR is one of the important numbers alongside the herd immunity threshold, and has implications for the scale of an epidemic and how seriously we should take a new disease.

Calculating an accurate IFR is challenging in the midst of any outbreak because it relies on knowing the total number of people infected — not just those who are confirmed through testing. But the fatality rate is especially difficult to pin down for COVID-19.

That’s partly because there are many people with mild or no symptoms, whose infection has gone undetected, and also because the time between infection and death can be as long as two months. Many countries are also struggling to count all their virus-related deaths, he says. Death records suggest that some of those are being missed in official counts.

Data from early in the pandemic overestimated how deadly the virus was, and then later analyses underestimated its lethality. Now, numerous studies — using a range of methods — estimate that in many countries some 5 to 10 people will die for every 1,000 people with COVID-19. “The studies I have any faith in are tending to converge around 0.5–1%,” says Russell.

But some researchers say that convergence between studies could just be coincidence. For a true understanding of how deadly the virus is, scientists need to know how readily it kills different groups of people. The risk of dying from COVID-19 can vary considerably depending on age, ethnicity, access to healthcare, socioeconomic status and underlying health conditions. More high-quality surveys of different groups are needed, these researchers say.

IFR is also specific to a population and changes over time as doctors get better at treating the disease, which can further complicate efforts to pin it down.

Getting the number right is important because it helps governments and individuals to determine appropriate responses.

Comment by Dr. Krishna Kumari Challa on June 17, 2020 at 8:08am: Do you know your behaviour on social media could be limiting the quality of your news feeds?

More than half the world's population use social media to keep up with the latest news and find a source of truth. But are they getting the facts and the right information? NO!

Some content is hidden from you while some news is made available to you based on your ‘mental make up’. So you are made to believe only a part of the world that suits you exist and that you are on the right path to seek it!

A lot of people may be unaware of the extent their news feed is altered by the click of a button when they dislike a post, or opt to see less of something on their news feed.

Throughout social media, a series of complex algorithms are in place to keep users engaged and visiting social media sites as long as possible. They want the user to have the feeling of 'you're right' so content is tailored to that person. This creates an environment of like-minded users who reinforce that person's opinions rather than providing balanced information.

So experts are making specific recommendations to empower individuals online, drawing on two approaches from behavioural sciences: nudging and boosting.

Nudging aims to steer people's behaviour by highlighting important information without imposing rules or bans. Nudging could be used, for example, to indicate whether content meets certain quality criteria—such as whether it stems from trustworthy sources.

Some sites recently took a step in this direction and started flagging some tweets with a fact-check warning.

The researchers say another possibility would be to make it more difficult for users to share information when an article fails to cite external references. For example, users might be required to click past a pop-up window.

Another option is what is called boosting, to enhance user competence in the long-term. This could, for instance, mean teaching people to determine the quality of a news item by looking at a set of variables, such as the sources being cited, that determine its likely quality.

It 's important to strengthen the Internet's potential to inform decision-making processes in democratic societies, bolstering them rather than undermining them.

'It's important for people to have autonomy to be able to control the content they receive, but at the same time be aware of the trustworthiness of their feeds and have more control over what information is provided.

Comment by Dr. Krishna Kumari Challa on June 17, 2020 at 6:21am: Could the cure for Irritable Bowel Disease be inside your mouth?

From heart disease to diabetes, poor oral health is often a reflection of a person's overall health and may even be the cause of systemic disease

A new collaborative study from the U-M Medical and Dental Schools reveals that inflammatory bowel disease (IBD), which included Crohn's disease and ulcerative colitis and afflicts millions of adults around teh world, may be the latest condition made worse by poor oral health. The team has been studying the gut microbiome—the collection of bacteria that are normally present in the gut— for years. It noted an emerging link in research literature between an overgrowth of foreign bacterial species in the guts of people with IBD—bacteria that are normally found in the mouth.

The new mouse study, published in Cell, shows two pathways by which oral bacteria appear to worsen gut inflammation.

In the first pathway, periodontitis, the scientific name for gum disease, leads to an imbalance in the normal healthy microbiome found in the mouth, with an increase of bacteria that cause inflammation. These disease-causing bacteria then travel to the gut.

However, this alone may not be enough to set off gut inflammation. The team demonstrated that oral bacteria may aggravate gut inflammation by looking at microbiome changes in mice with inflamed colons.

The normal gut microbiome resists colonization by exogenous, or foreign, bacteria. However, in mice with IBD, the healthy gut bacteria are disrupted, weakening their ability to resist disease-causing bacteria from the mouth." The team found that mice with both oral and gut inflammation had significantly increased weight loss and more disease activity.

In the second proposed pathway, periodontitis activates the immune system's T cells in the mouth. These mouth T cells travel to the gut where they, too, exacerbate inflammation. The gut's normal microbiome is held in balance by the action of inflammatory and regulatory T cells that are fine-tuned to tolerate the resident bacteria. But oral inflammation generates mostly inflammatory T cells that migrate to the gut, where they, removed from their normal environment, end up triggering the gut's immune response, worsening disease.

"This exacerbation of gut inflammation driven by oral organisms that migrate to the gut has important ramifications in emphasizing to patients the critical need to promote oral health as a part of total body health and wellbeing. This study importantly implies that clinical outcomes in IBD may be improved by monitoring oral inflamation—an intriguing concept.

ExoMars spots unique green glow at the Red Planet

ESA's ExoMars Trace Gas Orbiter has detected glowing green oxygen in Mars' atmosphere—the first time that this emission has been seen around a planet other than Earth.

On Earth, glowing oxygen is produced during polar auroras when energetic electrons from interplanetary space hit the upper atmosphere. This oxygen-driven emission of light gives polar auroras their beautiful and characteristic green hue.

The aurora, however, is just one way in which planetary atmospheres light up. The atmospheres of planets including Earth and Mars glow constantly during both day and night as sunlight interacts with atoms and molecules within the atmosphere. Day and night glow are caused by slightly different mechanisms: night glow occurs as broken-apart molecules recombine, whereas day glow arises when the sun's light directly excites atoms and molecules such as nitrogen and oxygen.

On Earth, green night glow is quite faint, and so is best seen by looking from an 'edge on' perspective—as portrayed in many spectacular images taken by astronauts aboard the International Space Station (ISS). This faintness can be an issue when hunting for it around other planets, as their bright surfaces can drown it out.

This green glow has now been detected for the first time at Mars by the ExoMars Trace Gas Orbiter (TGO), which has been orbiting Mars since October 2016.

Studying the glow of planetary atmospheres can provide a wealth of information about the composition and dynamics of an atmosphere, and reveal how energy is deposited by both the sun's light and the solar wind—the stream of charged particles emanating from our star.
