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!"

Albedo is highest in the frozen areas of the world, and mirror-like clean snow and ice with high levels of albedo reflect up to 90 percent of the sun's energy.
It is one of Earth's major cooling agents, along with lands and oceans that absorb excess heat and planet-warming greenhouse gas emissions.
Many countries have promised to plant billions of trees as a bulwark against global warming but not all efforts deliver for the planet equally, this study showed.
Moist, tropical environments like the Amazon and Congo Basin boasted high carbon storage and low changes in albedo, making them ideal locations for restoring forest cover.
The opposite was true in temperate grasslands and savanna.
Even projects in the best locations were probably delivering 20 percent less cooling than estimated when changes to 'albedo' were taken into account.
Restoring forests delivered undeniable benefits for people and the planet, such as supporting ecosystems and providing clean air and water, among many.
(But) we can't put trees everywhere. We don't have enough money or time or resources or people or seedlings.
And so it's really about making the most of limited investments and getting the greatest climate return per hectare of investment, according to researchers.

Planting trees in the wrong places can actually contribute to global warming, scientists said recently, but a new map identifies the best locations to regrow forests and cool the planet.
Trees soak up carbon dioxide and restoring areas of degraded woodlands or planting saplings to boost forest cover is one tool in the fight against climate change.
But in some cases, more trees means less sunlight is reflected back from the earth's surface and more heat is absorbed by the planet, according to a study in the journal Nature Communications.
There are some places where putting trees back leads to net climate negative outcomes. Scientists had already understood that restoring tree cover led to changes in albedo—the amount of solar radiation bounced back off the planet's surface—but didn't have the tools to account for it.
Using new maps, researchers were able to consider, for the first time, the cooling effect from trees and the warming caused by decreased albedo.
They found that projects that didn't factor albedo into the equation overestimated the climate benefit of additional trees by between 20 to 80 percent.
But the maps also provide the tools to help policymakers identify where best to funnel scarce resources for maximum climate impact.
There's also lots of places still where restoring tree cover is a great idea for climate change Scientists are just trying to help people find those spots.

To understand the reasons for different shapes of hyphae, researchers combined theory and experiments to investigate fungi and water molds from across nature. They first employed physics-based models of inflationary tip growth to determine all "possible" shapes of hyphae. Surprisingly, the shapes of "actual" hyphae found in nature assumed only a small subset of the possible shapes.
The researchers hypothesized that the limited shapes observed in nature reflected "survival of the fittest," and that the many possible shapes not observed in real fungi were, for some reason, weaker evolutionary rejects. To explore this idea, they examined the growth rate of hyphae with different shapes to create a fitness landscape for hyphae.
Their eureka moment came when they realized that the shapes of hyphae were intimately connected to their ability to grow fast.
A fitness landscape is like a topographic map that visualizes the evolution of an organism: every species wanders through its fitness landscape by testing whether or not random mutations in its genes increase its growth rate, or fitness. A species only stops its restless wandering when a new mutation decreases its fitness—that is, when it is at a fitness peak.
However, researchers found that fitness landscapes can be much more rich than a system of peaks and valleys. In fact, they found that the fitness landscape for hyphae contained an overhanging cliff, or tipping point, and that this acts as a barrier to evolution, strongly limiting the shapes of fungal hyphae. Accordingly, they predicted that hyphae with shapes near the brink of the tipping point would be particularly vulnerable to small environmental, chemical, or genetic changes.
The researchers tested their prediction by treating fungi near the tipping point with small amounts of chemicals that affected hyphal growth. They used one chemical that reduces pressure within the hyphae and another derived from a sea sponge that blocks the hypha's ability to deliver cellular components to the tip of the cell. Both treatments caused the same dramatic effect: the hyphae elongated much more slowly and with a strange nub shape not found in nature.
These findings explain hyphal shape diversity in an enormous, diverse, and important group of species. More broadly, they also demonstrate an important new evolutionary principle: that fitness landscapes can have instabilities, or tipping points, that impose strict constraints on complex traits, like biological form.
The researchers think that their results have critical implications for our understanding of many ecological and evolutionary systems. For example, those species whose evolution is subject to a tipping point may be the most vulnerable to the gradual increase in temperature caused by climate change.
Their findings could also aid in the development of new antimicrobials against disease-causing fungi by identifying vulnerabilities in their growth associated with an evolutionary tipping point.
A fitness landscape instability governs the morphological diversity of tip-growing cells, Cell Reports (2024). DOI: 10.1016/j.celrep.2024.113961. www.cell.com/cell-reports/full … 2211-1247(24)00289-4
Part 2
Scientists have found a "tipping point" in the evolution of fungi that throttles their growth and sculpts their shapes. The findings, published in the journal Cell Reports, demonstrate how small changes in environmental factors can lead to huge changes in evolutionary outcomes.
Fungi are nature's great composters. They wait within the forest floor to feed on fallen trees and autumn leaves, releasing essential nutrients from these plants back into the Earth.
Although fungi often bring to mind mushroom caps, fungi also have underground "roots" called mycelia. Mycelia are made up of thousands of interconnected, microscopic, finger-like cells called hyphae that grow into vast networks. Hyphae worm their way through the soil by growing from their tips. To do so, they inflate themselves, similar to the long balloons used to make balloon animals.
Their elongated forms allow hyphae to locate and consume nutrients within the soil. But not all hyphae are the same shape: some have rounded tips, while others are pointed. The hyphae of water molds—fungus-like pathogens that cause blight in crops—are particularly pointy.
A major challenge in biology is to identify the specific evolutionary factors that determine the shape—or form—of a given organism.

People with diabetes, atrial fibrillation (a common type of irregular heart rhythm) and treated high blood pressure were at highest risk of going on to develop heart and circulatory diseases.
Nearly half of those at highest risk smoked or were living with obesity. Modeling showed that if all current smokers living with obesity were supported to lose weight and quit smoking, the mean 10-year risk in this group would fall from nearly 22% to around 16%.

Recent research casts a new light on the nuanced interplay between gender and cancer, uncovering significant sex-specific disparities in copy number alterations (CNA) across various cancer types.
Published in Health Data Science, this study delineates the intricate ways in which these alterations influence cancer biology, offering a beacon for future therapeutic strategies.
At the crux of cancer research, understanding the divergent paths this disease takes in men and women is paramount. These latest findings delve into the heart of this divergence, revealing distinct genomic imbalances that underscore the importance of a gender-tailored approach in cancer prognosis and treatment.
The study unveils pronounced differences in genomic instability, particularly in cancers of the kidney, lung, liver, and head and neck, spotlighting the profound impact of sex-biased CNAs on gene expression and their potential as prognostic biomarkers. Remarkably, over 60% of genes within these CNA regions are significantly swayed by these alterations, with approximately 14% of their mRNA abundance being influenced by both gender and CNA.
Insights into these gender-specific genetic alterations pave the way for more personalized cancer care, highlighting the necessity of integrating gender considerations into prognostic models and therapeutic interventions.
Further validating its methodology, the study corroborates the robustness of the CNGPLD tool over traditional statistical approaches, enhancing the accuracy of detecting sex-specific genetic differences. Notably, the research expands its implications beyond the widely acknowledged sex disparities in lung and kidney cancers, identifying critical sex-biased CNA regions in head and neck cancer and lower-grade glioma.
Researchers envision a future where these findings catalyze the development of gender-specific biomarkers and therapeutic avenues, reinforcing the commitment to personalized medicine.

Low health literacy is a problem for a substantial proportion of people with moderate to severe traumatic brain injury (TBI), according to research published in The Journal of Head Trauma Rehabilitation (JHTR).
Personal health literacy as an individual's ability to find, understand, and use information about health and health services to make well-informed health decisions for themselves and/or others.
Researchers emphasize that health literacy can impact the comprehension, assimilation, and utilization of health care education and recommendations, and they urge clinicians to attend to health literacy when providing education and recommendations to individuals with TBI.

Although the study's observational design means it could not prove cause and effect, the findings possess strong biological plausibility since some of the specific metabolites highlighted in this study can only be produced by bacteria and not by the human body.
The study also relied on self-reported dietary fiber intake from participants. Dietary fiber is important to metabolic health, and we're beginning to understand why.
Zheng Wang et al, Gut Microbiota and Blood Metabolites Related to Fiber Intake and Type 2 Diabetes, Circulation Research (2024). DOI: 10.1161/CIRCRESAHA.123.323634

Eating more dietary fiber may help prevent type 2 diabetes by promoting beneficial gut bacteria and substances produced during metabolism, according to new research in Hispanic adults.
Consistent evidence suggests diabetes-protective effects of dietary fiber intake, but exactly how does that protection occur?
Consistent evidence suggests diabetes-protective effects of dietary fiber intake, but exactly how that protection occurs remained unclear until recently.
Discovering the connections between dietary fiber, gut bacteria, metabolites and type 2 diabetes—a leading risk factor for heart disease, stroke and kidney disease—could lead to more effective prevention of the condition.
For example, identifying which bacteria and metabolites in the body are linked to type 2 diabetes risk paves the way for personalized diets and treatments to improve gut and metabolic health for people at risk.
The study, published in Circulation Research, looked at data from up to 11,000-plus participants in the ongoing Hispanic Community Health Study/Study of Latinos.
The researchers found that higher fiber intake was associated with specific "good" gut bacteria and certain favorable metabolites in the blood—some of which were actually produced by gut bacteria. Those gut microbes and metabolites were associated with lower risk of developing type 2 diabetes during an average follow-up of six years.
This is new evidence of why a higher intake in dietary fiber is beneficial, specifically to reduce the incidence of new-onset type 2 diabetes.
Dietary fiber is mostly found in fruits, vegetables, nuts, whole grains and cereals. It cannot be broken down, and much of it passes through the system undigested. Its most well-known job is to promote regular bowel movements. But the new research suggests fiber might also be feeding bacteria in the gut.
Bacteria can affect disease risk through a vast array of mechanisms. The complexity was both surprising and fascinating, revealing the deep and nuanced interactions within our gut microbiome.
