     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!

A potential new treatment for premature aging diseases keeps stem cells fresh longer

The drug helps keep stem cells telomeres long, preventing them from aging too quickly.

The ends of our DNA, called telomeres, get shorter as we age. Our cells lose a bit of telomere every time they divide. This shortening is a normal and needed process that serves a protective function against cancer. This is because the older our cells get, the more likely they are to have accumulated damage or mutations that make them function incorrectly. Telomere shortening helps to take old cells that are reaching their “best before date” off the shelf before they can cause trouble.

But this can backfire: cells can shorten their telomeres too quickly, age rapidly, and die. This is what causes a subset of genetic premature aging diseases, including idiopathic pulmonary fibrosis, forms of aplastic anemia, and a rare disease called dyskeratosis congenita. Unfortunately, there are currently no available drug-based therapies for treating telomere-driven premature aging diseases.

Now, a candidate drug has found a new potential purpose in treating premature aging disease. 

This drug, called RG7834, was originally identified as an inhibitor of hepatitis B virus (HBV). While it has been found to be well-tolerated in short-term administration to living organisms (like rodents and primates), this drug does not cure HBV, and is not yet publicly available. Interestingly, the host cell proteins affected by RG7834 are two enzymes that modify many different RNAs. These enzymes can cause degradation of host cell RNA — so RG7834 keeps RNA around that the cell otherwise might get rid of.

**SARS-CoV-2 uses 'genome origami' to infect and replicate inside host cells

Scientists at the University of Cambridge, in collaboration with Justus-Liebig University, Germany, have uncovered how the genome of SARS-CoV-2—the coronavirus that causes COVID-19—uses genome origami to infect and replicate successfully inside host cells. This could inform the development of effective drugs that target specific parts of the virus genome, in the fight against COVID-19.

Most current work to find drugs and vaccines for COVID-19 is focused on targeting the proteins of the virus. Because the shape of the RNA molecule is critical to its function, targeting the RNA directly with drugs to disrupt its structure would block the lifecycle and stop the virus replicating.

the team uncovered the entire structure of the SARS-CoV-2 genome inside the , revealing a network of RNA-RNA interactions spanning very long sections of the genome. Different functional parts along the genome need to work together despite the great distance between them, and the new structural data shows how this is accomplished to enable the  life cycle and cause disease.

"The RNA genome of coronaviruses is about three times bigger than an average viral RNA genome—it's huge

In all cells the genome holds the code for the production of specific proteins, which are made when a molecular machine called a ribosome runs along the RNA reading the code until a '' tells it to terminate. In coronaviruses, there is a special spot where the ribosome only stops 50% of the times in front of the stop sign. In the other 50% of cases, a unique RNA shape makes the ribosome jump over the stop sign and produce additional viral proteins. By mapping this RNA structure and the long-range interactions involved, the new research uncovers the strategies by which coronaviruses produce their proteins to manipulate our cells.

The genome of most human viruses is made of RNA rather than DNA. Ziv developed methods to investigate such long-range interactions across viral RNA genomes inside the host , in work to understand the Zika virus . This has proved a valuable methodological basis for understanding SARS-CoV-2.

**Has the hidden matter of the universe been discovered?

Astrophysicists consider that around 40% of the ordinary matter that makes up stars, planets and galaxies remains undetected, concealed in the form of a hot gas in the complex cosmic web. Today, scientists at the Institut d'Astrophysique Spatiale (CNRS/Université Paris-Saclay) may have detected, for the first time, this hidden matter through an innovative statistical analysis of 20-year-old data.

**Coronavirus testing finally gathers speed

The imminent large-scale rollout of rapid coronavirus tests promises to aid public health responses to COVID-19 — but a rapid home test remains elusive.

Gold-catalyzed reaction releases an active drug to kill cancer cells

Drugs that are activated inside the body with catalytic quantities of gold could offer a new option for treating cancer and other diseases.

Using metals to convert masked "prodrugs" into their active forms inside the body is an emerging area of biomedical research. These drug-release reactions are designed to be triggered by metals that are not naturally present in the body, providing a new way to trigger drug release that promises to increase the efficacy and reduce the side effects of a therapy.

Seeing dark matter in a new light

A small team of astronomers have found a new way to 'see' the elusive dark matter haloes that surround galaxies, with a new technique 10 times more precise than the previous-best method.

Scientists currently estimate that up to 85% of the mass in the universe is effectively invisible. This "" cannot be observed directly, because it does not interact with light in the same way as the  that makes up stars, planets, and life on Earth.

So how do we measure what cannot be seen? The key is to measure the effect of gravity that the dark matter produces. It's like looking at a flag to try to know how much wind there is. You cannot see the wind, but the flag's motion tells you how strongly the wind is blowing.

The new research focuses on an effect called weak gravitational lensing, which is a feature of Einstein's general theory of relativity. The dark matter will very slightly distort the image of anything behind it.

Weak gravitational lensing is already one of the most successful ways to map the dark matter content of the Universe. Now, the team has used the ANU 2.3m Telescope in Australia to map how gravitationally lensed  are rotating. Because we know how stars and gas are supposed to move inside galaxies, we know roughly what that galaxy should look like. By measuring how distorted the real galaxy images are, then we can figure out how much dark matter it would take to explain what we see. The new research shows how this velocity information enables a much more precise measurement of the lensing effect than is possible using shape alone.

Startling Case Study Finds Asymptomatic COVID-19 Carrier Who Shed Virus For 70 Days

A team of researchers and doctors has now reported the case of one woman with leukemia who had no symptoms of COVID-19 but 70 days after her first positive test, she was still shedding infectious SARS-CoV-2 particles.

This result is much longer than previous reports of hospitalised adults found shedding infectious SARS-CoV-2 virus up to 20 days after their COVID-19 diagnosis, plus other accounts of people shedding genetic material from the virus up to 63 days after their symptoms first appeared.

The new report should alert doctors and public health experts alike to the fact that people without symptoms and with weakened immune systems, such as cancer patients, can seemingly shed the SARS-CoV-2 virus for a really long time. In this case, even months.

"Although it is difficult to extrapolate from a single patient, our data suggest that long-term shedding of infectious virus may be a concern in certain immunocompromised patients," the research team wrote in their paper describing the case.

New research traces the origins of trench fever

First observed among British Expeditionary Forces in 1915, trench fever sickened an estimated 500,000 soldiers during World War I. Since then, the disease has become synonymous with the battlefield. But now, new research from an international team of scientists has uncovered evidence challenging this long-held belief.

The research, published this week in PLOS ONE, outlines the discovery of DNA evidence of the disease in civilian remains predating WWI by thousands of years. In total, the team analyzed bone fragments and teeth of 145 individuals alive between the 1st and 19th centuries. Approximately 20% of those remains contained traces of Bartonella quintana, the bacteria responsible for trench fever. 

Epidemiologists and researchers used real-time polymerase chain reaction testing to detect B. quintana DNA within the remains.

Once contracted, there are diseases, like trench fever, that can leave traces within your DNA and can integrate your DNA with further information. This means that once a person dies, even as far back as 2,000 years ago, it is still possible to find traces of the bacterium that infected them.

 The discovery sheds light on the complex history of trench fever and begins answering historical questions about the lives of people in this region during the 3rd and 4th centuries.

While most associate this disease with WWI and WWII, occurrences of trench fever are still reported today, most prominently within homeless populations. The bacteria are spread to humans through contact with body lice (Pediculus humanus corporis), making poor personal hygiene a primary factor in its spread and infection rate. Researchers hope that by tracing the progression of B. quintana through history, they're able to identify ways to better manage the spread of the disease today.
