         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!"

Keeping web-like NETs from clogging blood vessels could improve stroke outcomes

Preventing the formation of a sticky, web-like substance that can form in blood vessels after a stroke could protect the brain and lead to better outcomes for patients, studies in mice suggest.

Stroke is a leading cause of disability in the world. The most common form, , occurs when a vessel-blocking clot impedes the flow of blood to the brain. Quick treatment to break up or remove the clot can restore blood flow and limit damage to the brain.

But according to the new study, the blood that comes rushing back carries cells with the potential to cause further harm. Brain damage can worsen even after a clot has been eliminated when immune cells in the blood release sticky webs, known as neutrophil extracellular traps (NETs), that further clog vessels.

Those NETs can gum up the vessels [in the brain] by trapping other cells and reducing the amount of blood flow, causing more brain injury. Markers of NETs correlated with poorer stroke outcomes in patients.

Researchers now found they could prevent these effects in a mouse model of stroke by treating animals with a NET-blocking compound.

New study reveals how to rejuvenate the immune system of elderly people and reduce their risk of infectious disease

A new study identifies a reason for why older adults are significantly more susceptible to infectious diseases than younger people. Study results also pave the way for new potential therapeutic targets to rejuvenate the immune system in older adults and thereby reduce their risk of infectious disease.

T cell immunity declines with aging, thereby increasing severity and mortality from infectious disease. T cells are the quarterback of the immune system and coordinate immune responses to fight off infections. The addition of complex and branched carbohydrate chains ('glycans') to proteins suppresses T cells function.

In this study, researchers show that the branched glycans increase with age in T cells from females more than in males due to age-associated increases in an important sugar metabolite (N-acetylglucosamine) and signaling by the T cell cytokine interleukin-7.

This research reveals that reversing the elevation in branched glycans rejuvenates human and mouse T cell function and reduces severity of Salmonella infection in old female mice.

This suggests several potential novel therapeutic targets to revitalize old T cells, such as altering branched glycans or the age-triggered elevation in serum N-acetylglucosamine and IL-7 signaling.

Haik Mkhikian et al, Age-associated impairment of T cell immunity is linked to sex-dimorphic elevation of N-glycan branching, Nature Aging (2022). DOI: 10.1038/s43587-022-00187-y

Reductions in PFAS levels from blood or plasma donations may be because PFAS are bound to proteins primarily found in the serum; many other organic pollutants are bound to fats.

The finding that plasma was more effective than blood donation might be because firefighters in the plasma donation group donated blood every six weeks, whereas those in the blood donation group donated every 12 weeks.

In addition, each plasma donation can amount to as much as 800mL compared with 470mL for whole blood.

Plasma PFAS concentrations are also about two times higher than blood PFAS concentrations, which could make plasma donation more efficient at reducing the body burden of PFAS chemicals.

This study provides the first avenue for affected individuals to remove PFAS from their bodies and redress the effects of their PFAS exposure.

New evidence shows blood or plasma donations can reduce the PFAS ‘forever chemicals’ in our bodies

You might have heard of PFAS, a synthetic chemical found in certain legacy firefighting foams, non-stick pans, carpets, clothes and stain- or water-resistant materials and paints.

PFAS stands for “per- and poly-fluorinated alkyl substances”. These molecules, made up of chains of carbon and fluorine atoms, are nicknamed “forever chemicals” because they don’t degrade in our bodies.

There is global concern about PFAS because they have been used widely, are persistent in the environment and accumulate in our bodies over time.

There was no way to reduce the amount of PFAS found in the body – until now.

But a new randomised clinical trial, published in the journal JAMA Network Open, has found regularly donating blood or plasma can reduce blood PFAS levels.

The trial involved 285 Fire Rescue Victoria staff and contractors with elevated levels of PFOS, a common detected type of PFAS used in some firefighting foams.

They were randomly allocated to donate plasma every six weeks, to donate whole blood every 12 weeks, or to make no donations (the control group) for 12 months.

Their PFAS levels were measured at four intervals: at recruitment, the start of the trial, after 12 months of following their treatment plan, and again three months later to test if the results were sustained.

Both blood and plasma donation resulted in significantly lower PFAS chemicals than the control group, and these differences were maintained three months later.

Plasma donation was most effective, resulting in a roughly 30% decrease in average blood serum PFAS concentrations over the 12-month trial period.

Decoy particles trick coronavirus as it evolves

They might look like cells and act like cells. But a new potential COVID-19 treatment is actually a cleverly disguised trickster, which attracts viruses and binds them, rendering them inactive.

As the ever-evolving SARS-CoV-2 virus begins to evade once promising treatments, such as monoclonal antibody therapies, researchers have become more interested in these "decoy" nanoparticles. Mimicking regular cells, decoy nanoparticles soak up  like a sponge, inhibiting them from infecting the rest of the body.

In a new study, Northwestern University  set out to elucidate the design rules needed make decoy nanoparticles effective and resistant to viral escape. After designing and testing various iterations, the researchers identified a broad set of decoys—all manufacturable using different methods—that were incredibly effective against the original virus as well as mutant variants.

In fact, decoy nanoparticles were up to 50 times more effective at inhibiting naturally occurring viral mutants, compared to traditional, protein-based inhibitor drugs. When tested against a viral mutant designed to resist such treatments, decoy nanoparticles were up to 1,500 times more effective at inhibiting infection.

Although much more research and clinical evaluations are needed, the researchers believe decoy nanoparticle infusions someday could potentially be used to treat patients with severe or prolonged viral infections.

Climatic variability might not drive evolutionary change as much as previously thought, study finds

A new study combining climate data with fossil records of large mammals that lived across Africa during the last 4 million years casts doubt on a long-standing hypothesis that repeated shifts in climate acted as major drivers of evolutionary change in mammals, including human ancestors.

Published in the journal Proceedings of the National Academy of Sciences, the study yields an African continent-wide synthesis of environmental variability during the Plio-Pleistocene, a period in Earth's history that spans roughly the last 5 million years and includes the last ice age about 20,000 years ago.

The study finds that environmental variability during that time mirrors changes in the Earth's orbit and orientation with respect to the sun, as predicted by a natural phenomenon known as Milankovic cycles. These cycles expose our planet to varying intensity of solar radiation, resulting in well-documented, cyclical effects on Earth's climate at various frequencies.

The researchers observed a long-term trend of increasing environmental variability across Africa attributable to variations in global ice volume and ocean temperature. The results did not, however, yield a significant correlation between environmental variation and rates of species origination or extinction, suggesting that environmental variability and species turnover may not be closely related.

Old skin cells reprogrammed to regain youthful function

Research  has developed a method to "time jump" human skin cells by 30 years, turning back the aging clock for cells without losing their specialized function. Work by researchers in the  Epigenetics research program has been able to partly restore the function of older cells, as well as rejuvenating the molecular measures of biological age. The research is published recently in the journal eLife, and while this topic is still at an early stage of exploration, it could revolutionize regenerative medicine.

As we age, our cells' ability to function declines and the  accumulates marks of aging. Regenerative biology aims to repair or replace cells including old ones. One of the most important tools in regenerative biology is our ability to create "induced" stem cells. The process is a result of several steps, each erasing some of the marks that make cells specialized. In theory, these stem cells have the potential to become any cell type, but scientists aren't yet able to reliably recreate the conditions to re-differentiate stem cells into all cell types.

The new method, based on the Nobel Prize-winning technique scientists use to make stem cells, overcomes the problem of entirely erasing cell identity by halting reprogramming part of the way through the process. This allowed researchers to find the precise balance between reprogramming cells, making them biologically younger, while still being able to regain their specialized cell function.
