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!"

Fire- safe fuel!
Chemical engineers have designed a fuel that ignites only with the application of electric current. Since it doesn't react to flames and cannot start accidental fires during storage or transport, it is a "safe" liquid fuel.
The fuel we're normally using is not very safe. It evaporates and could ignite, and it's difficult to stop that.
It is much easier to control the flammability of our fuel and stop it from burning when we remove voltage.
When fuel combusts, it is not the liquid itself that burns. Instead, it is the volatile fuel molecules hovering above the liquid that ignite on contact with oxygen and flame. Removing an oxygen source will extinguish the flame, but this is difficult to do outside of an engine.
If you throw a match into a pool of gasoline on the ground, it's the vapor of the gas that's burning. You can smell that vapor and you instantly know it's volatile. If you can control the vapour, you can control whether the fuel burns.
The base of the new fuel is an ionic liquid, which is a form of liquified salt. It is similar to the salt we use to flavour food, which is sodium chloride. The one researchers used for this project has a lower melting point than table salt, low vapour pressure, and is organic.
Once in the lab, the research team modified the ionic liquid's formula, replacing the chlorine with perchlorate. Then, they used a cigarette lighter to see if the resulting liquid would burn.
Next the team tried an application of voltage followed by a lighter flame, which did ignite. Once they shut off the current, the flame was gone, and they were able to repeat that process over and over again—applying voltage, seeing smoke, lighting the smoke so it burned, then turning it off. It's a system they could start and stop very quickly.
Adding more voltage to the liquid resulted in larger flames with more energy output. As such the approach could also act like a metering or throttling system in an engine.

A new study of the genetic blueprints of more than 600 types of carrot shows that three specific genes are required to give carrots an orange color. Surprisingly, these three required genes all need to be recessive, or turned off. The paper's findings shed light on the traits important to carrot improvement efforts and could lead to better health benefits from the vegetable.
Normally, to make some function, you need genes to be turned on. In the case of the orange carrot, the genes that regulate orange carotenoids—the precursor of vitamin A that have been shown to provide health benefits—need to be turned off.
According to the researchers, orange carrot could have resulted from white and yellow carrot crosses, as white and yellow carrots are at the base of the phylogenetic tree for the orange carrot. Also, carotenoids got their name because they were first isolated from carrots.
Population genomics identifies genetic signatures of carrot domestication and improvement and uncovers the origin of high carotenoid orange carrots, Nature Plants (2023). DOI: 10.1038/s41477-023-01526-6
Epicardial patches are carefully engineered tissue patches that can be placed near or on a patient's heart. These devices can help doctors to diagnose and treat a variety of heart conditions, including arrhythmia and heart attacks (i.e., myocardial infarctions).
In recent years, several engineers and medical researchers have been trying to develop these devices, yet many solutions proposed so far are not ideal. Specifically, most epicardial patches created so far are designed to be affixed onto the heart via a medical procedure known as "suturing," which can be both challenging and risky. Researchers recently developed an alternative epicardial patch that could be much easier to apply in clinical settings. This patch, introduced in Nature Electronics, is both stretchable and adhesive; thus, it does not need to be affixed onto a patient's heart through the suturing process.
Considering the highly irregular surface of the heart, the existing devices with low adhesiveness often become detached due to continuous cardiac contraction/relaxation in long term. To overcome such issues, facile and instantaneous and even robust adhesion to cardiac tissues is essential. Furthermore, when attached to the heart for an extended period, the materials used in epicardial devices should be exceptionally soft to avoid causing any tissue compression.
Researchers set out to develop a new adhesive epicardial patch that effectively overcomes the limitations of previously proposed designs. The patch they created now can be instantly attached to tissue on the heart's surface and could easily be fabricated on a large-scale.
Notably, their patch does not exert any unnecessary pressure on the heart's tissue for extended periods of time, which could improve both its safety and efficacy. It is comprised of three different but co-existing materials, namely a liquid-phase conducting composite, a network-shaped substrate, and an ionic adhesive.
The combination of these materials eliminates the need to suture the patch to the heart, making it easy to implement for medical professionals with varying degrees of experience, while also reducing the risk of complications associated with the suturing procedure.

Researchers tested the safety and feasibility of gene delivery to multiple brain regions using a noninvasive, ultrasound-based technique in rodents, and their findings suggest that the efficiency of gene delivery improves within each targeted site when more sites are opened.
The work used focused ultrasound energy to safely make the blood-brain barrier permeable. The technique is known as focused ultrasound blood-brain barrier opening (FUS-BBBO).
The procedure also permits the passage of proteins and other small molecules in the other direction—that is, from the brain into the bloodstream—where they can be readily sampled.
Many disorders affect large brain regions or the entire brain, but delivery of gene therapy to these regions is difficult.
When a gene-delivery vector is injected into the brain with a needle, it often only diffuses a few millimeters. To treat the entire brain, one would need to perform thousands of injections, which would be difficult and possibly harmful. With FUS-BBBO, such surgical delivery could be circumvented.
Researchers now tested the efficiency and safety of opening 105 sites simultaneously with positive results in most regions of the brain. Surprisingly, their findings suggest that the efficiency of gene delivery improves within each targeted site when more sites are opened.

When we wash our face with a cleanser, our skin can start to feel tight. With the application of a favorite moisturizer, that feeling often goes away. This perception of our skin might seem subjective, but researchers recently revealed the mechanism behind these feelings.
Their work, published in PNAS Nexus, demonstrates how mechanical changes at the outer surface of our skin translate into sensations and provides a quantitative approach for determining how people will perceive their skin after using a moisturizer or cleanser.
Our skin is the largest organ in our body and it's constantly exposed to the environment around us. The outermost layer of our skin—the stratum corneum—acts as a barrier to keep out unwanted chemicals and bacteria and to keep in moisture. When we use a harsh cleanser, it strips away some of the lipids that hold in moisture, causing the stratum corneum to contract. A good moisturizer increases the water content of the stratum corneum, causing it to swell.
The mechanical forces created by this shrinking or swelling propagate through the skin to reach mechanoreceptors—sensory receptors that turn mechanical force into neurological signals—below the epidermis, which then fire off signals to the brain that we interpret as a feeling of skin tightness.
The researchers studied the effects of nine different moisturizing formulas and six different cleansers on donor skin samples from three locations on the human body—cheek, forehead, and abdomen. They measured changes in the stratum corneum in the lab and then fed that information into a sophisticated model of human skin to predict the signals that the mechanoreceptors would send.

An artist's conceptual rendering of the antihydrogen atoms contained within the magnetic trap of the ALPHA-g apparatus. As the field strength at the top and bottom of the magnetic trap is reduced, the antihydrogen atoms escape, touch the chamber walls and annihilate. Most of the annihilations occur beneath the chamber, showing that gravity is pulling the antihydrogen down.

Part 2
Physicists studying antihydrogen—an anti-proton paired with an antielectron, or positron—have conclusively shown that gravity pulls it downward and does not push it upward. At least for antimatter, antigravity doesn't exist.
The experimental results have been reported in the Sept. 28 issue of the journal Nature by a team representing the Antihydrogen Laser Physics Apparatus (ALPHA) collaboration at the European Center for Nuclear Research (CERN) in Geneva, Switzerland.
The gravitational acceleration of antimatter that the team comes up with is close to that for normal matter on Earth: 1 g, or 9.8 meters per second per second (32 feet per second per second). More precisely, it was found to be within about 25% (one standard deviation) of normal gravity.
It surely accelerates downwards, and it's within about one standard deviation of accelerating at the normal rate.
Albert Einstein's theory of general relativity, though conceived before antimatter was discovered in 1932, treats all matter identically, implying that antimatter and matter respond the same to gravitational forces. All normal matter, such as protons, neutrons and electrons, have anti-particles that bear the opposite electrical charge and, when they encounter their normal matter counterpart, annihilate completely.

Tropical cyclones are extreme weather events, characterized by a circular form and formation over warm tropical oceans experiencing low atmospheric pressure, high winds and heavy rain. Tropical storms exceed 39 miles per hour (mph), while hurricanes experience sustained winds of 74mph and above.
The warm waters fuel the continuation of the cyclone, consequently cooling the surface of the ocean, and high wind speeds increase currents. The latter results in mixing of the layers of the ocean, bringing deeper and cooler water to the surface. In doing so, this can help to reduce the warm water fuel to cyclones, causing them to slow down or even cease altogether.
New research published in Geophysical Research Letters has turned towards technology to model the effects of tropical cyclones on oceans, in particular sea surface temperatures. This is important as the temperature can impact wider ecosystem responses, as well as the organisms that call the oceans home.
The machine learning-based random forest method used data from a 20-year period beginning in 1998 to train the system and help predict the evolution of sea surface temperature over time and space within the northwest Pacific Ocean (equator to 30°N, 100–160°E), one of the most active zones for tropical cyclones.
The research work showed that stronger intensity, larger and slower-moving tropical cyclones in areas with a shallow mixed ocean layer tend to have a greater cooling effect on the surface waters. Storm intensity and speed have a greater local effect, while the overall size of the cyclone, pre-storm ocean mixed layer depth and sea surface temperature impact the cooling effect over a larger area.

Research has looked into the susceptibility of older adults to scammers. In a paper, "Vulnerability of Older Adults to Government Impersonation Scams," published in JAMA Network Open, researchers tested 644 older adults with an experiment designed to mimic a government impersonation scam.
Participants averaged age 85.6 and were part of the Rush Memory and Aging Project (MAP), an ongoing cohort study of common chronic conditions related to aging. As part of the experiment, they were exposed to deceptive materials through mailers, emails, and phone calls by a live agent, mimicking a government impersonation scam.
Results were classified by three engagement groups: no engagement, engagement with skepticism, and conversion (those who engaged without skepticism).
Of the 644 participants, 441 (68.5%) did not engage, 97 (15.1%) engaged but raised skepticism, and 106 (16.4%) comprised the conversion group. Of those converted, nearly three-quarters provided personal information.
The research revealed that factors like cognition, financial literacy, and awareness of fraud scams were associated with the type of engagement. Those in the skeptical engagement group had the highest cognitive scores and financial literacy, while the conversion group had the lowest scam awareness.
According to the Federal Trade Commission, phone calls are the most common and most effective method used by fraudsters for targeting older adults.

Research led by multiple institutions in China has examined how small, furry, viral vectors affect the spread and evolution of viruses. They report the identification of 669 viruses, including 534 novel viruses, greatly expanding our knowledge of the mammalian virome, including previously unknown coronaviruses and orthorubulaviruses.
In their paper, "Host traits shape virome composition and virus transmission in wild small mammals," published in Cell, the team used meta-transcriptomic sequencing of internal organ and fecal samples from 2,443 wild bats, rodents, and shrews from four Chinese habitats. Viruses were identified in nearly all animals studied.
Researchers identified viruses related to known human or domestic animal pathogens (e.g., Rotavirus A, Seoul virus, Wenzhou mammarenavirus), including coronaviruses, which have caused diseases like SARS and COVID-19. There were also newly identified viruses from the orthorubulaviruses, porcine epidemic diarrhea virus (PEDV), swine acute diarrhea syndrome coronaviruses (SADS-CoVs), and SARS-related coronaviruses.
The study provided robust evidence of cross-species virus transmission. For instance, viruses were found in multiple species of wild small mammals, indicating that these viruses can move between different animal species, potentially including humans.
The team observed cross-species virus transmission at taxonomic levels across species, genus, family, and order, where the same virus was found in three or more mammalian species. Viruses with multi-organ distributions within hosts were more likely to be found in other host species. This suggests that if a virus is present in multiple internal organs, it has a higher chance of spreading to other species.
Bats are often considered to harbor more viruses than rodents. Of the animals sampled in the study, bats did have the highest richness, followed by rodents and shrews. While the total number of viruses identified in bats was more than that in rodents, the average number of viruses identified per species of bats and rodents was similar.
