         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!

People only pay attention to new information when they want to

A new paper in the Journal of the European Economic Association, published by Oxford University Press, indicates that we tend to listen to people who tell us things we'd like to believe and ignore people who tell us things we'd prefer not to be true. As a result, like-minded people tend to make one another more biased when they exchange beliefs with one another.

While it would reasonable to think that people form decisions based on evidence and experience alone, previous research has demonstrated that  have "motivated beliefs;" They believe things in part because they would like such things to be true. Motivated beliefs (and the reasoning that leads to them) can generate serious biases. Motivated beliefs have been speculated to explain the proliferation of misinformation on online forums.

The experiment conducted supports a lot of popular suspicions about why biased beliefs might be getting worse in the age of the internet. We now get a lot of information from social media and we don't know much about the quality of the information we're getting. As a result, we're often forced to decide for ourselves how accurate various opinions and sources of information are and how much stock to put in them. Our results suggest that people resolve this quandary by assigning credibility to sources that are telling us what we'd like to hear and this can make biases due to motivated reasoning a lot worse over time.

Mechanical buckling of petals produces iridescent patterns visible to bees

Flowers are employing a materials science phenomenon typically associated with failures in structural engineering to produce exquisite three-dimensional petal patterns to lure pollinators.

In  "buckling" is a dirty word with the buckling of beams and columns leading to —and is something that engineers want to avoid.

But for some plants, buckling is being employed to advantage.

Flowers use several different strategies to lure pollinators. Chemical color from pigments is just one of these strategies and recent research is finding that iridescence could be just as important for attracting pollinators like bees.

This optical effect is produced by an intricate pattern of nano-scale ridges on the surface of petals that diffract light to cause iridescence, like that seen on the surface of CDs or soap bubbles, but how the plant develops these ridges was not known.

Research from the University of Cambridge has demonstrated that plants employ buckling to precisely alter the deformation of the surface of petals in . The findings are published in Cell Reports today.

Mechanical buckling can pattern the light-diffracting cuticle of Hibiscus trionum, Cell Reports (2021). DOI: 10.1016/j.celrep.2021.109715

Our mobile phones are covered in bacteria and viruses… and we never wash them

Comment by Dr. Krishna Kumari Challa on September 14, 2021 at 11:31am

In this case, the siRNA is designed to specifically target the mRNA which carries instructions for the PCSK9 protein. It binds to its target mRNA and destroys the instructions, which significantly reduces the amount of these proteins that are produced.

Gene therapies are usually delivered using a viral vector – a virus-like vehicle that delivers genes to our cells in the same way a virus might infect them. So far, viral vector therapies have been used to treat rare genetic blood disorders, genetic blindness and spinal muscular atrophy.

Although viral vectors are very effective with one treatment, it may be impossible to deliver a second dose if needed due to adverse immune reactions. These drugs are also extremely costly.

Because of this, many of the gene silencing drugs currently being investigated are delivered using a different technique. Known as non-viral vector gene therapies, these deliver the drug using a nanoparticle which protects it from degradation in the blood so it can be delivered specifically to the target – such as the liver, which is the target of the cholesterol jab.

A Clever 'Gene Silencing' Injection Has Been Approved For Treating High Cholesterol

cholesterol-busting jab to save thousands of lives in UK

The revolutionary new treatment, Inclisiran, is delivered as an injection twice a year and can be used alongside statins, adding to the options available to patients to help control their cholesterol levels.

It has been estimated that Inclisiran could prevent 55,000 heart attacks and strokes, saving 30,000 lives within the next decade.

It will mainly be prescribed to patients who suffer with a genetic condition that leads to high cholesterol, those who have already suffered a heart attack or stroke, or those who haven't responded well to other cholesterol-lowering drugs, such as statins.

This is an emerging therapeutic technique that works by targeting the underlying causes of a disease, rather than the symptoms it causes. It does this by targeting a particular gene, and preventing it from making the protein that it produces.

Until now, most treatments using gene silencing technology have been used to treat rare genetic diseases. This means the cholesterol jab will be one of the first gene silencing drugs used to treat people on a wider scale.

Researchers are also currently investigating whether gene silencing could be used to treat a wide variety of health conditions, including Alzheimer's disease and cancer.

Gene silencing drugs work by targeting a specific type of RNA (ribonucleic acid) in the body, called "messenger" RNA. RNAs are found in every cell of the body, and play an important role in the flow of genetic information.

But messenger RNA (mRNA) is one of the most important types of RNA our body has, as it copies and carries genetic instructions from our DNA and makes specific proteins depending on the instructions.

In the case of the cholesterol jab, gene silencing works by targeting a protein called PCSK9 and degrading it. This protein is involved in regulating cholesterol in our bodies, but occurs in excess in people with high levels of LDL cholesterol (the "bad" cholesterol). Preventing this protein from being produced in the first place will reduce cholesterol levels.

Gut flora composition may impact susceptibility to konzo, a neurological disease caused by world staple crop cassava

Konzo is a severe, irreversible neurologic disease that results in paralysis. It occurs after consuming poorly processed cassava -- a manioc root and essential crop for DRC and other low-income nations. Poorly processed cassava contains linamarin, a cyanogenic compound. While enzymes with glucosidase activity convert starch to simple sugars, they also break down linamarin, which then releases cyanide into the body.

 Differences between gut flora and genes from konzo-prone regions of the Democratic Republic of Congo (DRC) may affect the release of cyanide after poorly processed cassava is consumed, according to a study with 180 children. Cassava is a food security crop for over half a billion people in the developing world. Children living in high-risk konzo areas have high glucosidase (linamarase) microbes and low rhodanese microbes in their gut, which could mean more susceptibility and less protection against the disease, suggest  researchers who led the study published in Nature Communications.

Knowing who is more at risk could result in targeted interventions to process cassava better or try to diversify the diet. An alternative intervention is to modify the microbiome to increase the level of protection. This is, however, a difficult task which may have unintended consequences and other side effects.

While the gut microbiome is not the sole cause of disease given that environment and malnourishment play a role, it is a required modulator. "Simply stated, without gut microbes, linamarin and other cyanogenic glucosides would pose little to no risk to humans."

Situs inversus totalis involves complete transposition (right to left reversal) of the thoracic and abdominal organs. 

The heart is not in its usual position in the left chest, but is on the right. Specifically related to the heart, this is referred to as dextrocardia (literally, right-hearted).The stomach, which is normally in the left upper abdomen, is on the right. In patients with situs inversus totalis, all of the chest and abdominal organs are reversed and appear in mirror image when examined or visualized by tests such as X-ray filming. Situs inversus totalis has been estimated to occur once in about 6-8,000 births. Situs inversus occurs in a rare abnormal condition that is present at birth (congenital) called Kartagener's syndrome.

CDC finds unvaccinated 11 times more likely to die of COVID

New U.S. studies released Friday show the COVID-19 vaccines remain highly effective against hospitalizations and death even as the extra-contagious delta variant swept the country.

One study tracked over 600,000 COVID-19 cases in 13 states from April through mid-July. As delta surged in early summer, those who were unvaccinated were 4.5 times more likely than the fully vaccinated to get infected, over 10 times more likely to be hospitalized and 11 times more likely to die, according to the Centers for Disease Control and Prevention.

Vaccination works! But ...

But as earlier data has shown, protection against coronavirus infection is slipping some: It was 91% in the spring but 78% in June and July, the study found.

So-called "breakthrough" cases in the fully vaccinated accounted for 14% of hospitalizations and 16% of deaths in June and July, about twice the percentage as earlier in the year.

An increase in those percentages isn't surprising: No one ever said the vaccines were perfect.
