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!"

Probably everyone has heard the conventional wisdom that a glass of wine a day is good for you—or you've heard some variation of it. The problem is that it's based on flawed scientific research, according to a new report in the Journal of Studies on Alcohol and Drugs.
Over the years, many studies have suggested that moderate drinkers enjoy longer lives with lower risks of heart disease and other chronic ills than abstainers do. That spurred the widespread belief that alcohol, in moderation, can be a health tonic. However, not all studies have painted such a rosy picture—and the new analysis sheds light on why.
In a nutshell, studies linking moderate drinking to health benefits suffer from fundamental design flaws, said lead researcher Tim Stockwell, Ph.D., a scientist with the Canadian Institute for Substance Use Research at the University of Victoria.
The major issue: Those studies have generally focused on older adults and failed to account for people's lifetime drinking habits. So moderate drinkers were compared with "abstainer" and "occasional drinker" groups that included some older adults who had quit or cut down on drinking because they'd developed any number of health conditions.
That makes people who continue to drink look much healthier by comparison, And in this case, the researchers noted, looks are deceiving.

Bear in mind, however, that an observational study like this can't definitively conclude that microplastics are causing the downstream heart effects; only that there is an association. The study did not consider other risk factors for cardiovascular disease, such as smoking, physical inactivity, and air pollution.
"Although we do not know what other exposures may have contributed to the adverse outcomes among patients in this study, the finding of microplastics and nanoplastics in plaque tissue is itself a breakthrough discovery that raises a series of urgent questions," such as how to reduce exposure, explained pediatrician, public health physician and epidemiologist Philip J. Landrigan, of Boston College, in an accompanying editorial.
Plastic production has exploded in the past two decades, only a fraction of which has been recycled, and yet rates of cardiovascular disease have been falling in some parts of the world, so more research is needed to understand the link between the two.

With microplastics previously found coursing through people's bloodstream, the researchers were reasonably concerned about heart health. Lab-based studies suggest microplastics can trigger inflammation and oxidative stress in heart cells, and impair heart function, alter heart rate, and cause scarring of the heart in animals such as mice.
"Observational data from occupational-exposure studies [also] suggest an increased risk of cardiovascular disease among persons who are exposed to plastics-related pollution, including polyvinyl chloride, than that seen in the general population," Marfella and colleagues write.
In the study, patients with microplastics in their excised plaques were 4.5 times as likely to have experienced a stroke, non-fatal heart attack or died from any cause after 34 months than people who had no detectable microplastics in the plaques that surgeons had removed.
The amount of microplastics, and even smaller particles called nanoplastics, was measured using a technique called pyrolysis–gas chromatography–mass spectrometry, and their presence confirmed using another method, stable isotopes analysis, which can distinguish between the carbon of human tissues and that of plastics made from petrochemicals.
Microplastics were also visible under powerful microscopes: The researchers observed plastic fragments with jagged edges inside immune cells called macrophages, and within the fatty plaques. Examining the tissue samples, the team also found higher levels of inflammatory markers in patients with microplastics in their plaques.

Virus spreading in Latin America may cause stillbirths and birth defects
Brazilian Ministry of Health tells doctors to closely monitor pregnant women infected with the little-known Oropouche virus
Fears over viral infection during pregnancy
The 2015-2016 outbreak of the Zika virus in Brazil caused thousands of birth defects after women were infected during pregnancy; now the country is facing the same fears with the Oropouche virus. Brazil’s health ministry has reported four cases of microcephaly — a type of reduced brain development — in newborns of infected mothers and one fetal death that might be associated with the virus. The virus is transmitted by Culicoides paraensis, a tiny midge found across the Americas. Cases of Oropouche fever have surged in Brazil since late 2022. “The cases are worrisome and a sign to be alert,” says virologist Amilcar Tanuri.

Evidence of ‘Dark oxygen’ production from the sea floor
A chemical reaction could be producing oxygen by splitting water molecules, but its source of energy remains unknown.
The phenomenon was discovered in a region strewn with ancient, plum-sized formations called polymetallic nodules, which could play a part in the oxygen production by catalysing the splitting of water molecules, researchers suspect. The findings are published in Nature Geoscience.
Something is pumping out large amounts of oxygen at the bottom of the Pacific Ocean, at depths where a lack of sunlight makes photosynthesis impossible. The find has surprised scientists and the source remains a mystery. The oxygen might be generated by metal-rich mineral deposits, or nodules. To researchers’ surprise, they measured voltages of up to 0.95 volts across the surface of the nodules. It is possible that the nodules catalyse the splitting of water into oxygen and hydrogen, but more experiments are needed.

A Chinese lunar probe found traces of water in samples of the moon's soil, scientists have said, as the country pushes its ambitious space program into high gear.
The Chang'e-5 rover completed its mission in 2020, returning to Earth with rock and soil samples from the moon.
The lunar samples "revealed the presence of trace water", the group of scientists from Chinese universities wrote in the Nature Astronomy journal published recently.

In the crowded urban landscape, where small electric vehicles—primarily scooters and bicycles—have transformed short distance travel, researchers are reporting a major national surge in accidents tied to "micromobility."
The researchers analyzed injuries and hospitalizations from electric bicycles, electric scooters, conventional bicycles and conventional scooters. The study, which appears July 23 in JAMA Network Open, is believed to be the first investigation into recent injury patterns in the U.S.
E-bicycle injuries doubled every year from 2017 to 2022, while e-scooter injuries rose by 45%. Injured e-riders tended to be slightly older and wore helmets less often than conventional riders. And e-scooter riders were more likely to sustain internal injuries than conventional scooter riders, while upper extremity injuries were more common among non-EV riders.

The AI model and human physicians answered questions from the New England Journal of Medicine's Image Challenge. The challenge is an online quiz that provides real clinical images and a short text description that includes details about the patient's symptoms and presentation, then asks users to choose the correct diagnosis from multiple-choice answers.
The researchers tasked the AI model to answer 207 image challenge questions and provide a written rationale to justify each answer. The prompt specified that the rationale should include a description of the image, a summary of relevant medical knowledge, and provide step-by-step reasoning for how the model chose the answer.
Nine physicians from various institutions were recruited, each with a different medical specialty, and answered their assigned questions first in a "closed-book" setting, (without referring to any external materials such as online resources) and then in an "open-book" setting (using external resources). The researchers then provided the physicians with the correct answer, along with the AI model's answer and corresponding rationale. Finally, the physicians were asked to score the AI model's ability to describe the image, summarize relevant medical knowledge, and provide its step-by-step reasoning.
The researchers found that the AI model and physicians scored highly in selecting the correct diagnosis. Interestingly, the AI model selected the correct diagnosis more often than physicians in closed-book settings, while physicians with open-book tools performed better than the AI model, especially when answering the questions ranked most difficult.
Importantly, based on physician evaluations, the AI model often made mistakes when describing the medical image and explaining its reasoning behind the diagnosis—even in cases where it made the correct final choice. In one example, the AI model was provided with a photo of a patient's arm with two lesions. A physician would easily recognize that both lesions were caused by the same condition. However, because the lesions were presented at different angles—causing the illusion of different colors and shapes—the AI model failed to recognize that both lesions could be related to the same diagnosis.
The researchers argue that these findings underpin the importance of evaluating multi-modal AI technology further before introducing it into the clinical setting.
Hidden Flaws Behind Expert-Level Accuracy of Multimodal GPT-4 Vision in Medicine, npj Digital Medicine (2024). DOI: 10.1038/s41746-024-01185-7. www.nature.com/articles/s41746-024-01185-7

Researchers have found that an artificial intelligence (AI) model solved medical quiz questions—designed to test health professionals' ability to diagnose patients based on clinical images and a brief text summary—with high accuracy. However, physician-graders found the AI model made mistakes when describing images and explaining how its decision-making led to the correct answer.
The findings, which shed light on AI's potential in the clinical setting, were published in npj Digital Medicine.
Integration of AI into health care holds great promise as a tool to help medical professionals diagnose patients faster, allowing them to start treatment sooner.
However, as this study shows, AI is not advanced enough yet to replace human experience, which is crucial for accurate diagnosis.
