     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".

"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 took in school. It’s life. We 're brought into existence by it!"

Drug turns cancer gene into 'eat me' flag for immune system

Tumor cells are notoriously good at evading the human immune system; they put up physical walls, wear disguises and handcuff the immune system with molecular tricks. Now,  researchers have developed a drug that overcomes some of these barriers, marking cancer cells for destruction by the immune system. The new therapy, described in Cancer Cell, pulls a mutated version of the protein KRAS to the surface of cancer cells, where the drug-KRAS complex acts as an "eat me" flag. Then, an immunotherapy can coax the immune system to effectively eliminate all cells bearing this flag.

How this jellyfish can live forever

The tiny translucent jellyfish Turritopsis dohrnii can revert to an immature polyp state and revive itself again and again — effectively making it immortal. Researchers have now sequenced the jellyfish’s genome and studied the genes involved in its rejuvenation. They found that genes associated with DNA storage were highly expressed in adult jellyfish, but reduced as the animals transformed into polyps. However, genes linked to pluripotency, or the ability of cells to turn into any cell type, were increasingly expressed as the jellyfish reverted.

After more than two years of the COVID-19 pandemic, you might picture a virus as a nasty spiked ball—a mindless killer that gets into a cell and hijacks its machinery to create a gazillion copies of itself before bursting out. For many viruses, including the coronavirus that causes COVID-19, the "mindless killer" epithet is essentially true.

Electric vehicles are now powering homes when utilities go down

Soon you'll be able to say goodbye to gas-powered generators and storage batteries if you want to power your home during a utility outage.

Your backup power source will be sitting in your driveway or garage, ready to keep your lights on, your fridge cold and your air conditioner blowing. Best of all, your power source will run silently, emit no dangerous exhaust, and be capable of safely running inside or outside during hurricanes and for at least a couple days afterward while your utility works to restore power. Electric vehicles with bidirectional charging capabilities are starting to hit the market as the auto industry transitions away from internal combustion engines. Just a handful of vehicles with so-called Vehicle-to-Home (V2H) capabilities are available now—and require costly aftermarket gear—but industry analysts expect their numbers to increase as more EVs come to market.

Bidirectional charging, as the term implies, is the capability to both receive and send power, and its availability in electric vehicles could provide a valuable layer of security to homeowners as severe weather events become more frequent and destructive.

New phases of water detected

Scientists  have discovered that water in a one-molecule layer acts like neither a liquid nor a solid, and that it becomes highly conductive at high pressures.

Much is known about how "bulk water" behaves: it expands when it freezes, and it has a high boiling point. But when water is compressed to the nanoscale, its properties change dramatically.

By developing a new way to predict this unusual behavior with unprecedented accuracy, the researchers have detected several new phases of water at the molecular level.

Water trapped between membranes or in tiny nanoscale cavities is common—it can be found in everything from membranes in our bodies to geological formations. But this nanoconfined water behaves very differently from the water we drink.

Until now, the challenges of experimentally characterizing the phases of water on the nanoscale have prevented a full understanding of its behaviour. But in a paper published in the journal Nature, researchers describe how they have used advances in computational approaches to predict the phase diagram of a one-molecule thick layer of water with unprecedented accuracy.

The researchers found that water which is confined into a one-molecule thick layer goes through several phases, including a "hexatic" phase and a "superionic" phase. In the hexatic phase, the water acts as neither a solid nor a liquid, but something in between. In the superionic phase, which occurs at higher pressures, the water becomes highly conductive, propelling protons quickly through ice in a way resembling the flow of electrons in a conductor.

The researchers found that the one-molecule thick layer of water within the nanochannel showed rich and diverse phase behavior. Their approach predicts several phases which include the hexatic phase—an intermediate between a solid and a liquid—and also a superionic phase, in which the water has a high electrical conductivity. The hexatic phase is neither a solid nor a liquid, but an intermediate, which agrees with previous theories about two-dimensional materials.

United in Science: We are heading in the wrong direction

World heading into ‘uncharted territory of destruction’, says climate report

Governments and businesses failing to change fast enough, says United in Science report, as weather gets increasingly extreme

The world’s chances of avoiding the worst ravages of climate breakdown are diminishing rapidly, as we enter “uncharted territory of destruction” through our failure to cut greenhouse gas emissions and take the actions needed to stave off catastrophe, leading scientists have said.

Despite intensifying warnings in recent years, governments and businesses have not been changing fast enough, according to the United in Science report published on Tuesday. The consequences are already being seen in increasingly extreme weather around the world, and we are in danger of provoking “tipping points” in the climate system that will mean more rapid and in some cases irreversible shifts.

The blood stem cell research that could change medicine of the future

Biomedical engineers and medical researchers have independently made discoveries about embryonic blood stem cell creation that could one day eliminate the need for blood stem cell donors.

The achievements are part of a move in regenerative medicine towards the use of "induced pluripotent stem cells" to treat disease, where stem cells are reverse engineered from adult tissue cells rather than using live human or animal embryos.

But while we have known about induced pluripotent stem cells since 2006, scientists still have plenty to learn about how cell differentiation in the human body can be mimicked artificially and safely in the lab for the purposes of delivering targeted medical treatment.

Two studies have emerged  in this area that shine new light on not only how the precursors to blood stem cells occur in animals and humans, but how they may be induced artificially.

In a study published today in Cell Reports, researchers demonstrated how a simulation of an embryo's beating heart using a microfluidic device in the lab led to the development of human blood stem cell "precursors," which are stem cells on the verge of becoming blood stem cells.

 They made a device mimicking the heart beating and the blood circulation and an orbital shaking system which causes shear stress—or friction—of the blood cells as they move through the device or around in a dish."

These systems promoted the development of precursor blood stem cells which can differentiate into various blood components—white blood cells, red blood cells, platelets and others. They were excited to see this same process—known as hematopoiesis—replicated in the device.

And in an article published in Nature Cell Biology in July, another group of researchers revealed the identity of cells in mice embryos responsible for blood stem cell creation. They researchers looked for the mechanism that is used naturally in mammals to make blood stem cells from the cells that line blood vessels, known as endothelial cells. They  identified the cells in the embryo that can convert both embryonic and adult endothelial cells into blood cells in the process.

Both studies are significant steps towards an understanding of how, when, where and which cells are involved in the creation of blood stem cells. In the future, this knowledge could be used to help cancer patients, among others, who have undergone high doses of radio- and chemotherapy, to replenish their depleted blood stem cells.

Research says  the best way to soothe a crying infant is by carrying them on a 5-minute walk

Most parents have experienced frustration when their infants cry excessively and refuse to sleep. Scientists have found that the best strategy to calm them down is by holding and walking with them for five minutes. This evidence-based soothing strategy is presented in a paper published September 13 in the journal Current Biology.

Many parents suffer from babies' nighttime crying. That's such a big issue, especially for inexperienced parents, that can lead to parental stress and even to infant maltreatment in a small number of cases.

researchers compared 21 infants' responses while under four conditions: being held by their walking mothers, held by their sitting mothers, lying in a still crib, or lying in a rocking cot. The team found that when the mother walked while carrying the baby, the crying infants calmed down and their heart rates slowed within 30 seconds. A similar calming effect occurred when the infants were placed in a rocking cot, but not when the mother held the baby while sitting or placed the baby in a still crib.

This suggests that holding a baby alone might be insufficient in soothing crying infants, contradicting the traditional assumption that maternal holding reduces infant distress. At the same time, movement has calming effects, likely activating a baby's transport response. The effect was more evident when the holding and walking motions continued for five minutes. All crying babies in the study stopped crying, and nearly half of them fell asleep.

But when the mothers tried to put their sleepy babies to bed, more than one-third of the participants became alert again within 20 seconds. The team found that all babies produced physiological responses, including changes in heart rate, that can wake them up the second their bodies detach from their mothers. However, if the infants were asleep for a longer period before being laid down, they were less likely to awaken during the process, the researchers found.

They recommend that parents hold crying infants and walk with them for five minutes, followed by sitting and holding infants for another five to eight minutes before putting them to bed. The protocol, unlike other popular sleep training approaches such as letting infants cry until they fall asleep themselves, aims to provide an immediate solution for infant crying. 

You might ask, don't we already know this? 

But we need science to understand a baby's behaviours, because they're much more complex and diverse than we thought. What you think you know is different from what a scientific study reveals.

Study finds antibiotics may make melanoma worse, by depleting the gut microbiome

The use of broad-spectrum antibiotics in mice with malignant melanoma, an aggressive form of skin cancer, accelerated their metastatic bone growth, likely because the drugs depleted the mice's intestinal flora and weakened their immune response, according to a new study by researchers.

The findings underscore the importance of the gut microbiome in overall health and suggest that doctors should carefully weigh the gastrointestinal effects when they use antibiotic therapies while treating cancer or other diseases.

Any disease or therapy that harms the gut microbiome could have a negative impact on our health.

This new study  found that the gut microbiome restrains the progression of melanoma bone lesions in mice by promoting the expansion of intestinal natural-killer (NK) cells and T helper (Th1) cells and enhancing their migration to the tumour site. Using oral antibiotics depleted the gut microbiome and reduced the population of intestinal NK cells and Th1 cells. This made the mice more vulnerable for tumour growth. They had a higher melanoma tumor burden than control mice whose gut microbiomes were intact.

Scientists discover how air pollution triggers lung cancer

Scientists  have identified the mechanism through which air pollution triggers lung cancer in non-smokers, a discovery one expert hailed as "an important step for science—and for society".

The research illustrated the health risk posed by the tiny particles produced by burning fossil fuels, sparking fresh calls for more urgent action to combat climate change. It could also pave the way for a new field of cancer prevention.

Scientists presented the research, which has not yet been published in a peer-reviewed journal, at the European Society for Medical Oncology's annual conference in Paris.

Air pollution has long been thought to be linked to a higher risk of lung cancer in people who have never smoked.

Researchers found that exposure to tiny PM2.5 pollution particles—which are less than 2.5 microns across—led to an increased risk of mutations in the EGFR gene. In laboratory studies on mice, they  showed that the particles caused changes in the EGFR gene as well as in the KRAS gene, both of which have been linked to lung cancer.

Finally, they analyzed nearly 250 samples of human lung tissue never exposed to carcinogens from smoking or heavy pollution.

Even though the lungs were healthy, they found DNA mutations in 18 percent of EGFR genes and 33 percent of KRAS genes.

They're just sitting there and the mutations seem to increase with age. On their own, they probably are insufficient to drive cancer.

But when a cell is exposed to pollution it can trigger a "wound-healing response" that causes inflammation. And if that cell harbours a mutation, it will then form a cancer.

In another experiment on mice, the researchers showed that an antibody could block the mediator—called interleukin 1 beta—which sparks the inflammation, stopping cancer from getting started in the first place.

LBA1 'Mechanism of action and an actionable inflammatory axis for air pollution induced non-small cell lung cancer in never smokers' will be presented by Charles Swanton during Presidential Symposium 1 on Saturday, 10 September, 16:30 to 18:00 CEST in Paris Auditorium. Annals of Oncology, Volume 33 Supplement 7, September 2022.
