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 September 15, 2020 at 7:24am: Blood Replacement Rescues Mice from Stroke Damage

When mice that had suffered a stroke were given blood from a healthy donor, they experienced less tissue and neurological damage.

https://www.the-scientist.com/news-opinion/blood-replacement-rescue...

Researchers have partially mitigated the effects of an ischemic stroke in mice simply by replacing a small amount of their blood with that of a healthy donor. Days after receiving the transplant, mice had less tissue damage surrounding the clot and suffered fewer neurological side effects compared to mice that had not received a blood infusion.

The results, published August 25 in Nature Communications, highlight the link between strokes in the brain and the immune system. At least some of the damage caused by strokes, the authors say, is the result of an overreactive immune response during which cells sent to an injury to fight infection and facilitate repair instead harm sensitive brain tissue.

“The initial impetus for the study was to determine the extent to which this immune response, which we know is very rapid and very profound, contributes to brain damage from stroke

Comment by Dr. Krishna Kumari Challa on September 15, 2020 at 6:31am: Big answers from tiny particles

A team of scientists led by Kanazawa University proposed a new mathematical framework to understand the properties of the fundamental particles called neutrinos. This work may help cosmologists make progress on the apparent paradox of the existence of matter in the Universe.

Comment by Dr. Krishna Kumari Challa on September 15, 2020 at 6:27am: Physicists 'trick' photons into behaving like electrons using a 'synthetic' magnetic field

Scientists have discovered an elegant way of manipulating light using a 'synthetic' Lorentz force—which in nature is responsible for many fascinating phenomena including the Aurora Borealis.

A team of theoretical physicists from the University of Exeter has pioneered a new technique to create tuneable artificial magnetic fields, which enable photons to mimic the dynamics of charged particles in real magnetic fields.

The team believe the new research, published in leading journal Nature Photonics, could have important implications for future photonic devices as it provides a novel way of manipulating light below the diffraction limit.

Comment by Dr. Krishna Kumari Challa on September 15, 2020 at 6:04am: Boron nitride nanofilms might replace antibiotics for protection against bacterial and fungal infections

Material scientists have presented antibacterial nano-coatings based on boron nitride, which are highly effective against microbial pathogens (up to 99.99%). They can become a safe alternative to the usual antibiotics in implantology since they do not have typical negative side effects.

Due to the significant increase in the number of surgical procedures around the world, scientists are addressing the problem of microbial infections caused by implants. It is especially serious during orthopedic and dental operations. It is no secret that concomitant drug therapy for inflammation around implants often leads to side effects due to the characteristic properties of the antibiotics, as well as the required high doses.

A group of scientists from has proposed a non-standard solution to the problem by investigating the interaction of antibiotic-resistant gram-negative bacteria Escherichia coli (E.coli) and a nanofilm consisting of a structured boron nitride surface. It turned out that such a coating inactivates 100% of bacterial cells after 24 hours.

Comment by Dr. Krishna Kumari Challa on September 15, 2020 at 5:59am: Bioactive nano-capsules to hijack cell behaviour to treat diseases

Many diseases are caused by defects in signaling pathways of body cells. In the future, bioactive nanocapsules could become a valuable tool for medicine to control these pathways. Researchers have taken an important step in this direction: They succeed in having several different nanocapsules work in tandem to amplify a natural signaling cascade and influence cell behaviour.

Comment by Dr. Krishna Kumari Challa on September 15, 2020 at 5:50am: Animals' magnetic 'sixth' sense may come from bacteria, new paper suggests

Scientists hypothesis to the Q why some animals have a magnetic 'sixth' sense, such as sea turtles' ability to return to the beach where they were born: the magnetic sense comes from a symbiotic relationship with magnetotactic bacteria.

Magnetotactic bacteria are a special type of bacteria whose movement is influenced by magnetic fields, including the Earth's.

Animals that sense Earth's magnetic field include sea turtles, birds, fish and lobsters. Sea turtles, for example, can use the ability for navigation to return to the beach where they were born.

Learning how organisms interact with magnetic fields can improve humans' understanding of how to use Earth's magnetic fields for their own navigation purposes. It can also inform ecological research into the effects of human modifications of the magnetic environment, such as constructing power lines, on biodiversity. Research into the interaction of animals with magnetic fields can also aid the development of therapies that use magnetism for drug delivery.

In the article, the researchers review the arguments for and against the hypothesis, present evidence published in support that has arisen in the past few years, as well as offer new supportive evidence of their own.

Their new evidence comes from microbes ( Metagenomic Rapid Annotations using Subsystems Technology database), the magnetotactic bacteria that had been found in animal samples. Scientists found for the first time, that magnetotactic bacteria are associated with many animals, including a penguin species, loggerhead sea turtles, bats and Atlantic right whales.

the hypothesis that animals use magnetic bacteria in a symbiotic way to gain a magnetic sense warrants further exploration but still needs more evidence before anything conclusive can be stated.

Comment by Dr. Krishna Kumari Challa on September 15, 2020 at 5:42am: Hints of life on Venus: Scientists detect phosphine molecules in high cloud decks

An international team of astronomers yesterday (14th sept., 2020) announced the discovery of a rare molecule—phosphine—in the clouds of Venus. On Earth, this gas is only made industrially, or by microbes that thrive in oxygen-free environments.

Astronomers have speculated for decades that high clouds on Venus could offer a home for microbes—floating free of the scorching surface, but still needing to tolerate very high acidity. The detection of phosphine molecules, which consist of hydrogen and phosphorus, could point to this extra-terrestrial 'aerial' life.

To create the observed quantity of phosphine on Venus, terrestrial organisms would only need to work at about 10% of their maximum productivity.

Gene-edited livestock 'surrogate sires' successfully made fertile

For the first time, scientists have created pigs, goats and cattle that can serve as viable "surrogate sires," male animals that produce sperm carrying only the genetic traits of donor animals.

could speed the spread of desirable characteristics in livestock and improve food production for a growing global population. It also would enable breeders in remote regions better access to genetic material of elite animals from other parts of the world and allow more precision breeding in animals such as goats where using artificial insemination is difficult.

Comment by Dr. Krishna Kumari Challa on September 14, 2020 at 8:18am: New fossil ape is discovered in India

A 13-million-year-old fossil unearthed in northern India comes from a newly discovered ape, the earliest known ancestor of the modern-day gibbon. The discovery fills a major void in the ape fossil record and provides important new evidence about when the ancestors of today's gibbon migrated to Asia from Africa. This discovery fills major gaps in the hominoid fossil record.

The fossil, a complete lower molar, belongs to a previously unknown genus and species (Kapi ramnagarensis) and represents the first new fossil ape species discovered at the famous fossil site of Ramnagar, India, in nearly a century.

Comment by Dr. Krishna Kumari Challa on September 14, 2020 at 6:31am: Math Shows How Famed Indus Valley Civilization May Have Been Toppled by Climate Change

There are competing hypotheses around the decline of the Indus Valley Civilization in South Asia some 3,000 years ago, but a new mathematical proof has identified that climate change could have been responsible.

Mathematical scientist Nishant Malik from the Rochester Institute of Technology crunched the numbers and found new evidence to back up the idea that shifting monsoon seasons and increasing drought might have helped bring about the collapse of the Bronze Age empire.

By analysing the presence of a particular isotope in stalagmites in a North Indian cave – which should reveal the amount of water that fell as rain over time – scientists have previously been able to estimate monsoon rainfall in the region over the past 5,700 years.

In the new research, Malik was able to identify patterns in this data showing a major shift in monsoon patterns as the civilization began to rise, and then a reverse shift that matched its decline.
