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!"

People's bias toward sacrificing unknown bystanders appears to stem from assuming the unidentified person is an enemy, according to a study published October 23, 2024, in the open-access journal PLOS ONE.
About as many civilians as soldiers die in war each year, some during strikes targeted at enemy combatants. There have been many reported cases of mistaking innocent civilians for enemy combatants, with the possibility of many more being unreported.
Researchers conducted five experiments to test when people assume unknown bystanders in a combat zone are enemies rather than civilians, reducing their concerns about collateral damage. A total of 2,204 participants were presented with a realistic moral dilemma: A military pilot must decide whether to bomb a dangerous enemy target, also killing a bystander.
In the study, few people endorsed bombing when the bystander was known to be an innocent civilian. However, when the bystander's identity was unknown, more than twice as many people endorsed the bombing despite no evidence they were enemies.
Bombing endorsement was predicted by attitudes toward total war: the theory that there should be no distinction between military and civilian targets in wartime conflict.
According to the authors, these findings have implications for military strategists who must decide whether to attack areas with enemy militants and unidentified bystanders. The results support a common tendency in people to assume the bystanders are enemies, with important consequences if they turn out to be innocent civilians.
The real-world cases of civilians struck by bombs could result from the same error in judgment reported in this study.

An "inflexible thinking style" could explain why some people are hesitant about taking a vaccine, new research has revealed. It is a finding that could have implications for public health policy, especially during pandemics.
Researchers conducted the first study evaluating the relationship between COVID-19 "vaccine hesitancy and cognitive flexibility."
Cognitive flexibility is how good people are at responding to changing situations and changing feedback, and especially when rules change. Inflexibility is generally described as the incapacity to adjust one's behavior in response to changing circumstances, update one's knowledge, and maintain optimum decision-making.
This explorative study found that those with greater vaccine hesitancy persisted with the same erroneous responses during a computerized test of flexible thinking, even when they received direct feedback telling them that their responses were no longer correct. This response pattern is the hallmark of a cognitively inflexible thinking style.
Vaccine hesitancy is quite common, occurring in approximately 12% of the population and may occur for multiple underlying reasons. In this study, researchers found the relationship between it and cognitive inflexibility can be predicted through an online test. This may be of value for public health policy in identifying this specific group.
The research, conducted between June 2021 and July 2022 after lockdown from COVID-19 was eased, has just been published in the Journal of Psychiatric Research.

Our bodies divest themselves of 60 billion cells every day through a natural process of cell culling and turnover called apoptosis. These cells—mainly blood and gut cells—are all replaced with new ones, but the way our bodies rid themselves of material could have profound implications for cancer therapies in a new approach developed by researchers.
They aim to use this natural method of cell death to trick cancer cells into disposing of themselves. Their method accomplishes this by artificially bringing together two proteins in such a way that the new compound switches on a set of cell death genes, ultimately driving tumor cells to turn on themselves.
The researchers describe their latest such compound in a paper published Oct. 4 in Science.
Apoptosis turns out to be critical for many biological processes, including proper development of all organs and the fine-tuning of our immune systems. That system retains pathogen-recognizing cells but kills off self-recognizing ones, thus preventing autoimmune disease.
Traditional treatments for cancer—namely chemotherapy and radiation—often kill large numbers of healthy cells alongside the cancerous ones. To harness cells' natural and highly specific self-destruction abilities, researchers developed a kind of molecular glue that sticks together two proteins that normally would have nothing to do with one another.
One of these proteins, BCL6, when mutated, drives the blood cancer known as diffuse large cell B-cell lymphoma. This kind of cancer-driving protein is also referred to as an oncogene. In lymphoma, the mutated BCL6 sits on DNA near apoptosis-promoting genes and keeps them switched off, helping the cancer cells retain their signature immortality.
The researchers developed a molecule that tethers BCL6 to a protein known as CDK9, which acts as an enzyme that catalyzes gene activation, in this case, switching on the set of apoptosis genes that BCL6 normally keeps off.
When the team tested the molecule in diffuse large cell B-cell lymphoma cells in the lab, they found that it indeed killed the cancer cells with high potency. They also tested the molecule in healthy mice and found no obvious toxic side effects, even though the molecule killed off a specific category of the animals' healthy B cells, a kind of immune cell, which also depends on BCL6.
They're now testing the compound in mice with diffuse large B-cell lymphoma to gauge its ability to kill cancer in a living animal.
The research team hopes that by blasting the cells with multiple different cell death signals at once, the cancer will not be able to survive long enough to evolve resistance, although this idea remains to be tested.

To test the obstetrical dilemma hypothesis, the research team first compared the available space in the birth canal of chimpanzees and humans, using the average distance between the fetal head and the pelvic bones while accounting for soft tissue contributions.
Using a three-dimensional virtual simulation of the birth process, they were able to show that the space in the chimpanzee pelvis is actually just as tight as it is in humans. Interestingly, after a detailed shape analysis, they also found that female chimpanzees have a more spacious pelvis than males, especially the smaller females, providing evidence of adaptations to deal with these space limitations.
The researchers also show that the great apes appear to trend towards humans in how neurologically immature, or how secondarily altricial their infants are compared to monkeys—again surprisingly similar to humans, although to a lesser magnitude.
Based on these intriguing parallels, the researchers propose a new hypothesis that the obstetrical dilemma developed gradually and became increasingly exacerbated over the course of evolution. This contradicts the previous theory that our long and difficult births emerged abruptly with the enlargement of the brain in Homo erectus.
The increase in body size in the ancestors of the great apes made their pelvis stiffer, which limited the ability of their ligaments to stretch during birth. In early hominins, the upright gait also led to a twisted bony birth canal, which required complex movements of the fetal head. This mechanism, rather than the narrowness of the birth canal, is likely the main cause of the difficult birth process in humans, the researchers argue.
The study shows that the remarkably complex human birth process is the result of gradual compromises during hominoid evolution. The difficult birth and the neurological immaturity of our newborns, with the long learning phase that follows, are a prerequisite for the evolution of our intelligence. At the same time, we humans are only at one extreme—we are not unique among primates, say the researchers.
Nicole M. Webb et al, Gradual exacerbation of obstetric constraints during hominoid evolution implied by re-evaluation of cephalopelvic fit in chimpanzees, Nature Ecology & Evolution (2024). DOI: 10.1038/s41559-024-02558-7

According to a new study, chimpanzees, like humans, must contend with a confined bony birth canal when giving birth. In humans, the problem is exacerbated by our unique form of upright walking, since this led to a twisting of the bony birth canal, while the fetal head grew larger. The obstetrical dilemma therefore evolved gradually over the course of primate evolution rather than suddenly in humans as originally argued.
The birth process in chimpanzees and other great apes is generally considered to be easy. This is usually attributed to a relatively large pelvis and the small head of their newborn. In contrast, human childbirth is both more complex and riskier when compared to other mammals.
According to the original obstetrical dilemma hypothesis, our birth difficulty stems from a conflict that arose during human evolution between adaptations in the pelvis for upright walking and an increase in our infants' brain size.
On the one hand, the pelvis shortened to improve balance while moving bipedally, while the baby's larger head still had to fit through the birth canal. As a solution to this dilemma, the shape of the pelvic bones differs between the sexes (with females having larger dimensions despite smaller body sizes), and human babies are born more neurologically immature than other primates, so that brain growth is delayed to the postnatal period.
An international team of researchers simulated birth in chimpanzees and humans and quantified the space between the bony birth canal and the fetal head. The work is published in the journal Nature Ecology & Evolution.
The study shows that narrow birth canals in relation to the infant head size are not unique to humans. Accordingly, the obstetrical dilemma hypothesis, which had previously been explained solely by the development of bipedalism and the size of the human brain, did not suddenly appear during the development of modern humans, but rather developed gradually over the course of primate evolution—and then intensified in humans, thus explaining the high rates of birth complications observed today.

A team of neuroscientists has found that people who have lost the ability to smell have slightly different breathing patterns than those with a normal sense of smell.
Anosmia is the inability to smell. Unfortunately, the condition was found to be a common symptom for people with COVID-19. The condition has been studied for hundreds of years and has a variety of causes, from depression to drug use, and negatively impacts quality of life. In this new effort, the research team has found yet another feature of the condition.
The researchers sought to address anecdotal accounts of people who could not smell and began "breathing funny" after contracting COVID-19. To find out if such accounts were true and to quantify the differences, the research team recruited 52 volunteers, 21 of whom were suffering from anosmia.
Each of the volunteers was fitted with a device that monitors breathing and each wore it for 24 hours. The research team found that those volunteers with anosmia did have slightly different than normal breathing patterns.
People without the condition, they note, have small inhalation peaks, which prior research suggests coincides with a suspected change in smell. People without the ability to smell had no such peaks.
The research team also found that they could identify with 83% accuracy which members of the group had anosmia simply by evaluating the breathing patterns. They suggest more research is required to determine if changes inbreathing patterns have later impacts, such as an increase in risk of developing depression.

Physicists observed a "black hole triple" for the first time: sheds new light on blackhole formation
The new system holds a central black hole in the act of consuming a small star that's spiraling in very close to the black hole, every 6.5 days—a configuration similar to most binary systems. But surprisingly, a second star appears to also be circling the black hole, though at a much greater distance. The physicists estimate this far-off companion is orbiting the black hole every 70,000 years.
That the black hole seems to have a gravitational hold on an object so far away is raising questions about the origins of the black hole itself. Black holes are thought to form from the violent explosion of a dying star—a process known as a supernova, by which a star releases a huge amount of energy and light in a final burst before collapsing into an invisible black hole.
The team's discovery, however, suggests that if the newly-observed black hole resulted from a typical supernova, the energy it would have released before it collapsed would have kicked away any loosely bound objects in its outskirts. The second, outer star, then, shouldn't still be hanging around.
Instead, the team suspects the black hole formed through a more gentle process of "direct collapse," in which a star simply caves in on itself, forming a black hole without a last dramatic flash. Such a gentle origin would hardly disturb any loosely bound, faraway objects.
Because the new triple system includes a very far-off star, this suggests the system's black hole was born through a gentler, direct collapse. And while astronomers have observed more violent supernovae for centuries, the team says the new triple system could be the first evidence of a black hole that formed from this more gentle process.

In a chaotic and emotionally charged response to the situation, surgeons declined to continue the procedure .
"It was very chaotic. Everyone was just very upset."
That's everybody's worst nightmare, right? Being alive during surgery and knowing that someone is going to cut you open and take your body parts out?
Deep concerns have been raised about the potential for errors such as these.
But these are rare cases. You don't have to worry.
Please donate your organs and those of your loved ones without any hesitation.
Man Declared Brain Dead Wakes Up as Organs About to Be Removed
This story brought back traumatic memories to me.
I decided to donate my mother's corneas when the doctors treating her declared her brain dead. But my sister was very scared. "What if she isn't actually dead?", she asked me, "What if she gets up again from her deep sleep? She won't have eyes to see!"
A case of a Kentucky man waking up as his organs were about to be harvested for donation has called into question the protocols used by hospitals and organ donation networks to qualify death.
Whistleblower Nyckoletta Martin outlined the horrifying case in a letter addressing the US House of Representatives Energy and Commerce Committee's September hearing on the nation's organ procurement and transplantation system.
While employed as an organ preservationist for Kentucky Organ Donor Affiliates (KODA), Martin had allegedly reviewed case notes on the October 2021 surgical procedure.
According to a report by the US public broadcasting organization National Public Radio (NPR), those case notes indicated the donor had shown signs of life following a clinical test to evaluate the heart's fitness for transplant purposes. The donor had woken up during his procedure that morning for a cardiac catheterization. And he was thrashing around on the table.
The patient at the center of the incident is 36-year-old Anthony Thomas 'TJ' Hoover II, who had been rushed to Baptist Health Hospital in Richmond, Kentucky, following a drug overdose. Declared brain dead in the wake of a cardiac arrest, TJ was removed from life support and prepared for organ donation in accordance with his wishes. TJ's sister Donna Rhorer was by her brother's side following his passing. Along with other family members, Rhorer recalled seeing TJ's eyes open and looking about on the way to the theater, to be told by staff this was a common reflex. It was only later when TJ displayed more exaggerated movements on the operating table and "was crying visibly" that medical staff in the room became alarmed.
