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 1, 2020 at 9:03am: DST researchers come up with simulation toolkit to safeguard secure quantum communication platforms

Researchers at Raman Research Institute (RRI), an autonomous institute of the Department of Science & Technology (DST), government of India have come up with unique simulation toolkit for end-to-end Quantum Key Distribution (QKD) simulation named as ‘qkdSim’, which is based on modular principles that allow it to be grown to different classes of protocols using various underpinning technologies.

The research led by professor Urbasi Sinha and her team, in collaboration with professor Barry Sanders from the University of Calgary, Canada is a part of the Quantum Experiments using Satellite Technology (QuEST) project, India’s first satellite-based secure quantum communication effort, supported by the Indian Space Research Organisation (ISRO).

The toolkit offers exhaustive inclusion of different experimental imperfections, both device-based as well as process-based. Thus their simulation results will match with actual experimental implementations to much better accuracy than any other existing toolkit, making it a QKD experimenter’s best friend.

As QKD is growing rapidly in academic, industrial, government, and defence laboratories, this newly developed simulation toolkit, accompanied by an instructive application to the uniquely designed B92 experiment, will be extremely influential, as per a statement. The B92 is a QKD protocol, which uses single photons and associated laws of Physics like the Uncertainty Principle and the No-Cloning theorem to assure perfect security.

“Secure error free communication protocols are assuming extraordinary importance for which Quantum key distribution (QKD) is an attractive solution, which relies on a cryptographic protocol. A shared random secret key known only to the communicating parties is employed to encrypt and decrypt messages. A unique property of quantum key distribution is that any break in attempt by an unauthorized party is immediately detected. This is because any process of measuring a quantum system creates detectable anomalies,” said Prof Ashutosh Sharma, Secretary, DST.

The research work is two-fold in its novelty as well as process development. On the one hand, they have developed a simulation toolkit, which bridges a significant gap in the QKD community. On the other hand, they have performed a novel implementation of what is called a prepare and measure QKD protocol (B92), which has higher key rates and lower quantum bit error rate than earlier reported works following similar source methodology.

Comment by Dr. Krishna Kumari Challa on July 1, 2020 at 8:19am: Buzzing to rebuild broken bone

Healing broken bones could get easier with a device that provides both a scaffold for the bone to grow on and electrical stimulation to urge it forward.

A group of biomedical engineers from UConn have developed a scaffold of non-toxic polymer that also generates a controllable electrical field to encourage bone growth. The scaffold helps the body bridge large fractures. Although many scientists are exploring the use of scaffolding to encourage bone growth, pairing it with electrical stimulation is new.

The team demonstrated the device in mice with skull fractures.

The electrical voltage the scaffold generates is very small, just a few millivolts. And uniquely for this type of device, the voltage is generated via remotely-controlled ultrasound. The ultrasound vibrates the polymer scaffolding, which then creates an electrical field (materials that create electricity from vibration, or vice versa, are called piezoelectric.) To help heal a thigh fracture, for example, the polymer scaffold can be implanted across the broken bone. Later, the person with the broken bone can wave the ultrasound wand over their own thigh themselves. No need for batteries, and no need for invasive removal surgery once the bone is healed.

"The electrical field relates to the natural signal generated by your body at the injury location. We can sustain that voltage, on demand and reversible," for however long is needed using ultrasound.

In addition to being non-toxic and piezoelectric, PLLA gradually dissolves in the body over time, disappearing as the new bone grows. The electric field created by the piezoelectric PLLA scaffold seems to attract bone cells to the site of the fracture and promote stem cells to evolve into bone cells. This technology can possibly be combined with other factors to facilitate regeneration of other tissues, like cartilage, muscles or nerves.

Comment by Dr. Krishna Kumari Challa on July 1, 2020 at 7:11am: A revolutionary new treatment alternative to corneal transplantation

Good news for the many patients who are unable to undergo corneal transplantation operation due to a severe worldwide shortage of donor corneas:

an effective and accessible solution called LiQD Cornea to treat corneal perforations without the need for transplantation.

Until now, patients on the waiting list have had their perforated corneas sealed with a medical-grade super glue, but this is only a short-term solution because it is often poorly tolerated in the eye, making transplantation necessary.

A synthetic, biocompatible and adhesive liquid hydrogel, LiQD Cornea, is applied as a liquid, but quickly adheres and gels within the corneal tissue. The LiQD Cornea promotes tissue regeneration, thus treating corneal perforations without the need for transplantation.

A cosmic mystery: Very Large Telescope captures the disappearance of a massive star

Using the European Southern Observatory's Very Large Telescope (VLT), astronomers have discovered the absence of an unstable massive star in a dwarf galaxy. Scientists think this could indicate that the star became less bright and partially obscured by dust. An alternative explanation is that the star collapsed into a black hole without producing a supernova.

Based on their observations and models, the astronomers have suggested two explanations for the star's disappearance and lack of a supernova, related to this possible outburst. The outburst may have resulted in the luminous blue variable being transformed into a less luminous star, which could also be partly hidden by dust. Alternatively, the team says the star may have collapsed into a black hole, without producing a supernova explosion. This would be a rare event: our current understanding of how massive stars die points to most of them ending their lives in a supernova.

Future studies are needed to confirm what fate befell this star.
