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!"

Laboratory studies and field research have identified four main ways in which animals are adversely affected by noise pollution: (i) hearing loss, with noise levels of 85 Decibel or higher; (ii) masking, such as the inability to hear important environmental and animal signals; (iii) increased heart rate and breathing; and (iv) behavioral effects. There is considerable intra-species variability, and this varies according to the characteristics of the noise. This may lead to territory abandonment and loss of reproduction.
Marine animals such as whales, which depend on sound for communication, can be affected by noise in various ways. Marine mammals live in a habitat that transmits little light but through which sound propagates well and quickly, even over great distances. For this reason, marine mammals rely on sound to communicate, explore the environment, find their prey and avoid obstacles. Research had shown that higher ambient noise levels also caused the animals to vocalize louder (“Lombard Effect”) and that the duration of the humpback whales’ song was longer when there was low-frequency sonar in the vicinity .
Exposure to noise can produce a wide range of effects on marine mammals. The low-level sound may be audible to animals without producing any visible effects; higher-intensity sound can disturb the animals, causing them either to move away or may produce other behavioral changes. Noise can increase the risk of death by modifying the delicate balance between predators and prey, interfering with the use of sounds in communication, especially in relation to reproduction and navigation.

Researchers have known for a while that noise from human activities is disruptive to aquatic life like dolphins and whales, but a new study by University of Denver researchers finds that human-generated noise can mask the harmony of cricket song, with profound effects across 15 species traits.
Among their findings, they report that at a certain noise level, human-generated sounds can reduce the rate of survival to adulthood and affect the number of hatched offspring. The researchers exposed crickets to four levels of sound often encountered in natural settings: silence, 50 decibels, 60 decibels and 70 decibels. At 70 decibels, a level associated with vacuum cleaners and busy streets, survival to adulthood was reduced.
Previous studies have found that human-generated sounds cause changes to birdsong as birds attempt to make themselves heard over traffic, but this is among the first studies to examine human influence on invertebrates as species numbers are collapsing.

An international research team has developed a system using nanotechnology that could allow people with diabetes to take oral insulin in the future. The researchers say the new insulin could be eaten by taking a tablet or even embedded within a piece of chocolate.
The new nano carrier, tested in mice, rats and baboon animal models, could help people with diabetes avoid side-effects linked to insulin injections such as hypoglycemia (a low blood sugar event, when too much insulin has been injected).
These animal studies have shown that the greatest strength of the nano-scale material is that it can react to the body's blood sugar levels. The coating dissolves and releases the insulin when there is a high concentration of blood sugar and importantly does not release the insulin in low blood sugar environments.
The new oral insulin uses a type of nano-scale material that is 1/10,000th the width of a human hair. The material acts similarly to acid resistant coating on tablets, which protects it from being destroyed by stomach acid. But this new coating instead surrounds individual insulin molecules and becomes a "nano carrier"—acting like a courier to ferry insulin molecules in the body to the places it needs to act.

A team of archaeologists, antiquities specialists, Bible scholars and mass spectrometry specialists, affiliated with several institutions in Israel working with one colleague from the U.K. and another from the U.S., has dated material uncovered in the First Temple in the city of David, in Jerusalem, to an unpreceded level of accuracy.
In their paper published in the Proceedings of the National Academy of Sciences, the group describes how they used radio-carbon dating, tree ring analysis and other techniques to accurately date artifacts collected from a dig site in one of the oldest parts of Jerusalem.
The ancient history of Israel, and most particularly the city of Jerusalem, has taken on increased significance over the past several decades as religious and political entities have used it to make claims about current rights to certain parts of the city. One such site is believed to be what has been described in ancient texts as the City of David.
The work by the team involved analysis of artifacts (such as seeds and a bat skull) found among strata dated to between 770 and 420 BC—which has been named the Hallstatt Plateau. The team performed 103 carbon-14 measurements, providing high-resolution results.
The researchers also dated material in the same strata using tree-ring measurements, which allowed for annual resolution. After dating the artifacts, the researchers looked for and found associations between the nature of the artifacts and reported historical events mentioned in several ancient texts, including the Bible.
The team found that they were able to date many of the artifacts to historical events, which allowed them to verify that the city was first settled sometime between the 12th and 10th century BC, and that it expanded westward thereafter. They also found evidence of an earthquake and the rebuilding that occurred thereafter during the 8th century BC—and the Babylonian destruction of the city of Jerusalem in 586 BC.

In translational patient-based studies, the team also analyzed human tissue, blood and stool samples from Weill Cornell Medicine's Jill Roberts Institute for Research in Inflammatory Bowel Disease Live Cell Bank. This analysis revealed that patients with inflammatory bowel disease, like the mice fed inulin, had higher levels of bile acids in their blood and stool and excessive levels of eosinophils in their intestine compared with people without the condition.
The results suggest that the inflammation cascade similar to that in the mice fed inulin is already primed in humans with inflammatory bowel disease, and dietary uptake of inulin may further exacerbate the disease.
These unexpected discoveries may help explain why high-fiber diets often exacerbate inflammatory bowel disease in patients. It may also help scientists develop therapeutic diets to reduce symptoms and gut damage in patients with inflammatory bowel disease or related conditions.
New therapies are urgently needed for these increasingly common gut conditions. Existing biologic therapies can increase the risk of developing infections or autoimmune diseases, which cause the immune system to attack the body.
The present study shows that not all fibers are the same in how they influence the microbiota and the body's immune system.
These findings could have broader implications for the delivery of precision nutrition to individual patients to promote their overall health based on their unique symptoms, microbiota composition and dietary needs.

Part 2
Inulin, a type of fiber found in certain plant-based foods and fiber supplements, causes inflammation in the gut and exacerbates inflammatory bowel disease in a preclinical model, according to a new study by investigators. The surprising findings could pave the way for therapeutic diets that may help ease symptoms and promote gut health.
The study, published March 20 in the Journal of Experimental Medicine, shows that inulin, which is found in foods such as garlic, leeks and sunchoke, as well as commonly used fiber supplements and foods with added fiber, stimulates microbes in the gut to release bile acids that increase the production of molecules that promote intestinal inflammation.
One such protein, IL-33, causes immune cells called group 2 innate lymphoid cells (ILC2s) to become activated, triggering an excessive immune response similar to an allergic reaction. That excessive immune response then exacerbates intestinal damage and symptoms in an animal model of inflammatory bowel disease.A group of researchers have discovered a potential "cosmic glitch" in the universe's gravity, explaining its strange behavior on a cosmic scale.
The paper is published in the Journal of Cosmology and Astroparticle Physics.
For the last 100 years, physicists have relied upon Albert Einstein's theory of "general relativity" to explain how gravity works throughout the universe. General relativity, proven accurate by countless tests and observations, suggests that gravity impacts not simply three physical dimensions but also a fourth dimension: time.
This model of gravity has been essential for everything from theorizing the Big Bang to photographing black holes.
But when we try to understand gravity on a cosmic scale, at the scale of galaxy clusters and beyond, we encounter apparent inconsistencies with the predictions of general relativity. It's almost as if gravity itself stops perfectly matching Einstein's theory. We are calling this inconsistency a 'cosmic glitch': gravity becomes around one percent weaker when dealing with distances in the billions of light years.
For more than twenty years, physicists and astronomers have been trying to create a mathematical model that explains the apparent inconsistencies of the theory of general relativity. Many of those efforts have taken place at Waterloo, which has a long history of cutting-edge gravitational research resulting from ongoing interdisciplinary collaboration between applied mathematicians and astrophysicists.
"Almost a century ago, astronomers discovered that our universe is expanding.
The farther away galaxies are, the faster they are moving, to the point that they seem to be moving at nearly the speed of light, the maximum allowed by Einstein's theory. Our finding suggests that, on those very scales, Einstein's theory may also be insufficient.
The research team's new model of a "cosmic glitch" modifies and extends Einstein's mathematical formulas in a way that resolves the inconsistency of some of the cosmological measurements without affecting existing successful uses of general relativity.
"Think of it as being like a footnote to Einstein's theory," the researchers say. "Once you reach a cosmic scale, terms and conditions apply."
"This new model might just be the first clue in a cosmic puzzle we are starting to solve across space and time".

Glioblastoma is among the most devastating diagnoses, with median survival around 15 months. The current standard of care involves surgery, radiation and some combination of chemotherapy.
In a first-ever human clinical trial of four adult patients, an mRNA cancer vaccine developed by scientists quickly reprogrammed the immune system to attack glioblastoma, the most aggressive and lethal brain tumour.
The results mirror those in 10 pet dog patients suffering from naturally occurring brain tumors whose owners approved of their participation, as they had no other treatment options, as well as results from preclinical mouse models. The breakthrough now will be tested in a Phase I pediatric clinical trial for brain cancer.
Reported May 1 in the journal Cell, the discovery represents a potential new way to recruit the immune system to fight notoriously treatment-resistant cancers using an iteration of mRNA technology and lipid nanoparticles, similar to COVID-19 vaccines, but with two key differences: use of a patient's own tumor cells to create a personalized vaccine, and a newly engineered complex delivery mechanism within the vaccine.
In less than 48 hours, the researchers could see these tumours shifting from what they refer to as 'cold'—immune cold, very few immune cells, very silenced immune response—to 'hot,' very active immune response.
The 10 pet dogs on which trials were done lived a median of 139 days, compared with a median survival of 30 to 60 days typical for dogs with the condition.

Most amniotic fluid cells are epithelial, but scientists knew very little about these cell populations. Everything changed when researchers started to look at the single cell level at what happened in the amniotic fluid.
used single-cell RNA sequencing to characterize the amniotic fluid of 12 patients and discovered subpopulations of epithelial cells that expressed markers typical of progenitors for the lung, kidney, and small intestine. The researchers cultured the tissue-specific progenitor cells, fed them a chemical cocktail to support growth, and watched as they proliferated, differentiated, and self-organized into 3D epithelial organoids. The mini-organs shared some transcriptomic and protein features found in their tissues of origin. For example, lung epithelial cells that developed and differentiated in culture had elevated expression of airway markers compared to their nondifferentiated counterparts. Similarly, kidney epithelial organoids expressed markers associated with renal tubules, which are integral components of the kidneys’ filtration system.
Although the amniotic fluid contained cells from other tissues, the researchers could not grow them into organoids, suggesting that they lack progenitor capabilities. Other research groups have successfully grown fetal organoids from somatic cells floating around the amniotic fluid, and the mini-organs generated using this approach are more complex.
reprogramming methods take up to 20 weeks to generate organoids. If the goal is to use organoids to inform prenatal interventions, timing is critical.
