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!"

Study suggests pollutant's toxicity could be decreased

Bacteria that can help defuse highly toxic dioxin in sediments in the Passaic River - a Superfund hazardous waste site - could eventually aid cleanup efforts at other dioxin-contaminated sites around the world, according to scientists.

Comment by Dr. Krishna Kumari Challa on August 20, 2020 at 6:44am: Doctors Used a Poop Transplant to Cure a Man Whose Gut Was Making Him Drunk

A rare syndrome in which the human gut brews its own alcohol has been successfully treated with a poop transplant when nothing else was working, marking the first such case in medical literature.

Known as auto-brewery syndrome (ABS), this extraordinary condition can leave patients feeling downright intoxicated, even if they haven't had a single thing to drink.

ABS is caused by microorganisms - usually fungi - in the gut feasting on recently-eaten carbohydrates to produce their own brew of alcohol.

Most of us have these fermenting microbes in small quantities, but in ABS the microbe populations and therefore the fermentation can grow out of control. This can sometimes occur after a course of antibiotics throws the gut balance off.

Initially, this is what brought a 47-year-old man to the hospital in Belgium. Since finishing a dose of antibiotics, he had been experiencing unexplained moments of inebriation. And it had been going on for two months.

The patient told doctors he hadn't consumed a drink in four days, and yet upon further testing, his blood ethanol levels were more than 17 times what's considered normal, or twice the legal limit in the United States.

Doctors diagnosed him with gut fermentation syndrome, or ABS, and prescribed oral anti-fungals and a low-carb diet. But it only helped a little. Even an increased dose of the high-potency anti-fungal medication amphotericin taken for four weeks appeared unsuccessful: The patient still felt inebriated and his wife reported she could smell the alcohol on his breath.

In recent years, poop transplants have been proposed as a promising new way to re-balance gut microbiota among certain groups of people. That said, they appear to only work against some infections, and there are potentially life-threatening risks that need to be taken into consideration.

However, the man was willing to try it, and the sample was voluntarily donated by his 22-year-old daughter. Luckily, the poop transplant worked wonderfully. Nearly three years later, the patient still remains free of ABS symptoms, and his blood ethanol levels have returned to normal.

Comment by Dr. Krishna Kumari Challa on August 20, 2020 at 6:39am: Newly Identified Social Trait Could Explain Why Some People Are Particularly Tribal

Having strong, biased opinions may say more about your own individual way of behaving in group situations than it does about your level of identification with the values or ideals of any particular group, new research suggests.

This behavioural trait – which researchers call 'groupiness' – could mean that individuals will consistently demonstrate 'groupy' behaviour across different kinds of social situations, with their thoughts and actions influenced by simply being in a group setting, whereas 'non-groupy' people aren't affected in the same way.

"It's not the political group that matters, it's whether an individual just generally seems to like being in a group," says economist and lead researcher Rachel Kranton from Duke University.

"Some people are 'groupy' – they join a political party, for example. And if you put those people in any arbitrary setting, they'll act in a more biased way than somebody who has the same political opinions, but doesn't join a political party."

Comment by Dr. Krishna Kumari Challa on August 20, 2020 at 5:53am: Zebra stripes and their role in dazzling flies

The mystery of why zebras have their characteristic stripes has perplexed researchers for several years. many popular theories such as their use as camouflage from predators, a cooling mechanism through the formation of convection currents and a role in social interactions have been discredited. Stripes acting to confuse predators is another common explanation, but it too is flawed when looking at the scientific data. Instead, mounting evidence suggests that it is parasitic flies that are confounded by the zebra's distinctive patterning.

scientists have now provided significant depth to this hypothesis by narrowing down the possible mechanism.

Previously, the same researchers had shown that blood-sucking horseflies would approach horses in striped rugs as often as plain rugs, but then failed to land or slow down when they got close.

Essentially, stripes dazzled the flies, forcing them to collide with the skin or fly away altogether. In their new study they explored a potential mechanism explaining how the stripes lead to this outcome: the aperture effect.

"The aperture effect is a well-known optical illusion that, in human vision, is also known as the barber-pole effect. Moving stripes, such as those on the rotating barber-pole signs outside barbershops, appear to move at right angles to the stripe, rather than in their true direction, so the pole appears to move upwards, rather than around its axle.

"We set out to see if this illusion also takes place in the eyes of biting flies as they come to land on striped hosts.

"As any fly approaches a landing surface, it will adjust its speed according to how quickly the surface expands across its vision, enabling a slowed and controlled landing.

"Stripes however could disrupt this 'optic flow' through the aperture effect, leading the fly to believe the landing surface is further away than reality. Thus, the fly fails to slow down or land successfully."

Despite its appeal to visual ecologists, this research found that the aperture effect is not the mechanism behind fly confusion through comparing fly landings on horses wearing striped versus checked rugs.

Since checked rugs provide visual input free from the aperture effect, one would expect flies to land on them without difficulty. Yet flies had real difficulties with this pattern—hardly landing on checked or striped rugs at all. Thus, stripes themselves are not unique to deterring tabanid horseflies, other patterns can be effective too.

Mystery gas discovered near center of Milky Way

An international team of researchers have discovered a dense, cold gas that's been shot out from the center of the Milky Way "like bullets"

When you drive out a lot of mass, you're losing some of the material that could be used to form stars, and if you lose enough of it, the galaxy can't form stars at all anymore.

"So, to be able to see hints of the Milky Way losing this star forming gas is kind of exciting—it makes you wonder what's going to happen next!

there's not only hot gas coming from the center of our galaxy, but also cold and very dense gas.

"This cold gas is much heavier, so moves around less easily.
