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!"

"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!

Comment by Dr. Krishna Kumari Challa on Wednesday: 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.

‘Alarming’ use of critical human antibiotics on crops

Farmers in parts of Asia are spraying antibiotics deemed “critical” for human medicine on rice crops, raising fears they may be fuelling antibiotic resistance, say researchers.

A 32-country survey of agricultural advisers found that many are prescribing the common human antibiotics streptomycin and tetracycline for insect infestations, fungal diseases and as general protection, as well as for bacterial infections.*

Comment by Dr. Krishna Kumari Challa on Tuesday: Engineers use 'DNA origami' to identify vaccine design rules

By folding DNA into a virus-like structure, MIT researchers have designed HIV-like particles that provoke a strong immune response from human immune cells grown in a lab dish. Such particles might eventually be used as an HIV vaccine.

The DNA particles, which closely mimic the size and shape of viruses, are coated with HIV proteins, or antigens, arranged in precise patterns designed to provoke a strong immune response. The researchers are now working on adapting this approach to develop a potential vaccine for SARS-CoV-2, and they anticipate it could work for a wide variety of viral diseases.

The rough design rules that are starting to come out of this work should be generically applicable across disease antigens and diseases. Because DNA molecules are highly programmable, scientists have been working since the 1980s on methods to design DNA molecules that could be used for drug delivery and many other applications, most recently using a technique called DNA origami that was invented in 2006 by Paul Rothemund.

In 2016, Bathe's lab developed an algorithm that can automatically design and build arbitrary three-dimensional virus-like shapes using DNA origami. This method offers precise control over the structure of synthetic DNA, allowing researchers to attach a variety of molecules, such as viral antigens, at specific locations.

Natural viruses are nanoparticles with antigens arrayed on the particle surface, and it is thought that the immune system (especially B cells) has evolved to efficiently recognize such particulate antigens. Vaccines are now being developed to mimic natural viral structures, and such nanoparticle vaccines are believed to be very effective at producing a B cell immune response because they are the right size to be carried to the lymphatic vessels, which send them directly to B cells waiting in the lymph nodes. The particles are also the right size to interact with B cells and can present a dense array of viral particles.

The findings from this study have the potential to guide HIV vaccine development, as the HIV antigen used in these studies is currently being tested in a clinical trial in humans, using a protein nanoparticle scaffold.

Because this approach allows for antigens from different viruses to be carried on the same DNA scaffold, it could be possible to design variants that target multiple types of coronaviruses, including past and potentially future variants that may emerge, the researchers say.

Your brain handles a perceived threat differently depending on how close it is to you.: Closer threats inspire a more primitive kind of fear. If it's far away, you engage more problem-solving areas of the brain. But up close, your animal instincts jump into action and there isn't as much reasoning, like when the guy at the haunted house jumps up right next to you.

Can anything withstand the immense heat of the Sun?

The Sun is surrounded by a layer of plasma which extends millions of miles into space, in some places reaching up to 3 million degrees Celsius (5.4 million degrees Fahrenheit).

There are no known materials that can exist as solids, liquids or gases at such extreme temperatures.

Protons, neutrons and electrons can withstand this heat as they are virtually indestructible, however they can only exist as plasma.

If you could somehow get past the corona to the surface of the Sun, where it is ‘only’ 5,500 degrees Celsius (9,900 degrees Fahrenheit), some liquids could exist.
