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!"

Normally when an antibody binds to a cell, it acts as a sort of tag, calling out for an immune cell to bind to the antibody and set off an efficient process of destroying the tagged cell. To stop this chain reaction, researchers devised a method to catch the antibodies before they bind to cells, preventing activation of the immune response.
The researchers genetically engineered three types of cells—insulin-producing pancreatic islet cells, thyroid cells, and CAR-T cells—so that each type made and displayed large numbers of a protein called CD64 on their surfaces.
On these engineered cells, CD64, which tightly binds the antibodies responsible for this type of immune rejection, acted as a kind of decoy, capturing the antibodies and binding them to the engineered cell, so they wouldn't activate immune cells.
Indeed this was the case when this approach was tested. This is clear proof-of-concept for this approach.
Tobias Deuse, Protection of cell therapeutics from antibody-mediated killing by CD64 overexpression, Nature Biotechnology (2023). DOI: 10.1038/s41587-022-01540-7. www.nature.com/articles/s41587-022-01540-7
Part2
Researchers have developed a novel, potentially life-saving approach that may prevent antibodies from triggering immune rejection of engineered therapeutic and transplant cells.
Rejection mediated by antibodies—as opposed to the chemical assault initiated by immune cells—has proven particularly tricky to resolve, a factor holding held back the development of some of these treatments. The new strategy, described in the Monday, Jan. 2, 2023 issue of Nature Biotechnology, involved using a "decoy" receptor to capture the antibodies and take them out of circulation before they could kill the therapeutic cells, that they treat as invading foreigners. The tactic may also be useful for organ transplants.
The most celebrated cellular therapies are chimeric antigen receptor (CAR) T-cell therapies. These CAR-T therapies are often used to successfully treat specific forms of lymphomas, a type of often-deadly cancer. But deploying them against solid tumors has proved much more difficult. Until recently, most CAR-T therapies have been made using the patient's own cells, but the long-term commercial viability of cellular therapies of all types will rely on "allogeneic" cells—mass-produced therapeutic cells grown from a source outside the patient. As with transplanted organs, the recipient's immune system is likely to treat any outsider cells, or tissues developed from them, as foreign and to reject them. This issue is likely to be a severe obstacle in any type of allogeneic cell transplantation.

Adults who stay well-hydrated appear to be healthier, develop fewer chronic conditions, such as heart and lung disease, and live longer than those who may not get sufficient fluids, according to a National Institutes of Health study published in eBioMedicine. Using health data gathered from 11,255 adults over a 30-year period, researchers analyzed links between serum sodium levels—which go up when fluid intake goes down—and various indicators of health. They found that adults with serum sodium levels at the higher end of a normal range were more likely to develop chronic conditions and show signs of advanced biological aging than those with serum sodium levels in the medium ranges. Adults with higher levels were also more likely to die at a younger age.
The results suggest that proper hydration may slow down aging and prolong a disease-free life.
The study expands on research the scientists published in March 2022, which found links between higher ranges of normal serum sodium levels and increased risk for heart failure. Both findings came from the Atherosclerosis Risk in Communities (ARIC) study, which includes sub-studies involving thousands of adults.
The researchers found that adults with higher levels of normal serum sodium—with normal ranges falling between 135-146 milliequivalents per liter (mEq/L)—were more likely to show signs of faster biological aging. This was based on indictors like metabolic and cardiovascular health, lung function, and inflammation.
The conclusion therefore was people whose serum sodium is 142 mEq/L or higher would benefit from evaluation of their fluid intake. Doctors may also need to defer to a patient's current treatment plan, such as limiting fluid intake for heart failure. The authors also cited research that finds about half of people worldwide don't meet recommendations for daily total water intake, which often starts at 6 cups (1.5 liters).
Decreased body water content is the most common factor that increases serum sodium, which is why the results suggest that staying well hydrated may slow down the aging process and prevent or delay chronic disease.
Natalia I. Dmitrieva et al, Middle-age high normal serum sodium as a risk factor for accelerated biological aging, chronic diseases, and premature mortality, eBioMedicine (2023). DOI: 10.1016/j.ebiom.2022.104404
Vaccination and boosting, especially when recent, helped to limit the spread of COVID-19 in California prisons during the first omicron wave, according to an analysis by researchers.
The study demonstrates the benefits of vaccination and boosting, even in settings where many people are still getting infected, in reducing transmission. And it shows the cumulative effects from boosting and the additional protection that vaccination gives to those who were previously infected. The likelihood of transmission fell by 11% for each additional dose.
A lot of the benefits of vaccines to reduce infectiousness were from people who had received boosters and people who had been recently vaccinated.
Vaccinated residents with breakthrough infections were significantly less likely to transmit them: 28% versus 36% for those who were unvaccinated. But the likelihood of transmission grew by 6% for every five weeks that passed since someone's last vaccine shot.
Natural immunity from a prior infection also had a protective effect, and the risk of transmitting the virus was 23% for someone with a reinfection compared to 33% for someone who had never been infected.
Those with hybrid immunity, from both infection and vaccination, were 40% less likely to transmit the virus. Half of that protection came from the immunity that one acquires from fighting an infection and the other half came from being vaccinated.

People with a condition known as dry eye disease are more likely than those with healthy eyes to suffer injuries to their corneas. Studying mice, researchers at Washington University School of Medicine in St. Louis have found that proteins made by stem cells that regenerate the cornea may be new targets for treating and preventing such injuries.
Dry eye disease occurs when the eye can't provide adequate lubrication with natural tears. People with the common disorder use various types of drops to replace missing natural tears and keep the eyes lubricated, but when eyes are dry, the cornea is more susceptible to injury.
We have drugs to treat this condition, but they only work well in about 10% to 15% of patients. In this new study involving genes that are key to eye health, researchers identified potential targets for treatment that appear different in dry eyes than in healthy eyes.
The researchers analyzed genes expressed by the cornea in several mouse models—not only of dry eye disease, but also of diabetes and other conditions. They found that in mice with dry eye disease, the cornea activated expression of the gene SPARC. They also found that higher levels of SPARC protein were associated with better healing.
Lin, Joseph B. et al, Dry eye disease in mice activates adaptive corneal epithelial regeneration distinct from constitutive renewal in homeostasis, Proceedings of the National Academy of Sciences (2023). DOI: 10.1073/pnas.2204134120. doi.org/10.1073/pnas.2204134120
As cells perform their everyday functions, they turn on a variety of genes and cellular pathways. Researchers have now coaxed cells to inscribe the history of these events in a long protein chain that can be imaged using a light microscope.
Cells programmed to produce these chains continuously add building blocks that encode particular cellular events. Later, the ordered protein chains can be labeled with fluorescent molecules and read under a microscope, allowing researchers to reconstruct the timing of the events.
This technique could help shed light on the steps that underlie processes such as memory formation, response to drug treatment, and gene expression.
If the technique could be extended to work over longer time periods, it could also be used to study processes such as aging and disease progression, the researchers say.

Researchers identify 100,000 new types of viruses
A groundbreaking study has discovered about 100,000 new types of previously unknown viruses , a ninefold increase in the amount of RNA viruses known to science until now. The viruses were discovered in global environmental data from soil samples, oceans, lakes, and a variety of other ecosystems. The researchers believe that the discovery may help in the development of anti-microbial drugs and in protecting against agriculturally harmful fungi and parasites.
Human brain organoids implanted into mouse cortex respond to visual stimuli for first time
A team of engineers and neuroscientists has demonstrated for the first time that human brain organoids implanted in mice have established functional connectivity to the animals' cortex and responded to external sensory stimuli. The implanted organoids reacted to visual stimuli in the same way as surrounding tissues, an observation that researchers were able to make in real time over several months thanks to an innovative experimental setup that combines transparent graphene microelectrode arrays and two-photon imaging.

Quasicrystals, as their name suggests, are crystal-like substances. They possess characteristics not found in ordinary crystals, such as a non-repeating arrangement of atoms. To date, quasicrystals have been found embedded in meteorites and in the debris from nuclear blasts. In this new effort, the researchers found one embedded in a sand dune in Sand Hills, Nebraska.
A team of researchers has found an incidence of a quasicrystal formed during an accidental electrical discharge.
Study of the quasicrystal showed it had 12-fold, or dodecagonal, symmetry—something rarely seen in quasicrystals. Curious as to how it might have formed and how it ended up in the sand dune, the researchers did some investigating. They discovered that a power line had fallen on the dune, likely the result of a lightning strike. They suggest the electrical surge from either the power line or the lightning could have produced the quasicrystal.
The researchers note that the quasicrystal was found inside of a tubular piece of fulgurite, which they suggest was also formed during the electrical surge due to fusing of melted sand and metal from the power line.
In looking at the quasicrystal using an electron microscope, the researchers were able to make out its composition. In so doing, they found bits of silicon dioxide glass, which told them that temperatures inside the sand dune during the electrical discharge had to have reached at least 1,710 degrees Celsius. They also found that the quasicrystal had been retrieved from an area of transition between melted aluminum alloy and silicate glass. Their work confirmed that the object they were studying was, indeed, a quasicrystal, and that it had a previously unseen composition.
The researchers conclude that finding a quasicrystal in such a place suggests that others are likely out there, as well, having formed due to lightning strikes or downed power lines. They also suggest their work could lead to techniques to create quasicrystals in the lab.

A type of chronic leukemia can simmer for many years. Some patients may need treatment to manage this type of blood cancer—called myeloproliferative neoplasms (MPN)—while others may go through long periods of watchful waiting. But for a small percentage of patients, the slower paced disease can transform into an aggressive cancer, called secondary acute myeloid leukemia, that has few effective treatment options. Little has been known about how this transformation takes place.
But now, researchers have identified an important transition point in the shift from chronic to aggressive leukemia. They have shown that blocking a key molecule in the transition pathway prevents this dangerous disease progression in mice with models of the disease and in mice with tumors sampled from human patients.
