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!"

Scientists Have Found a Way to Make Foldable Keyboards Out of Any Paper
--A new way to make bacteria more sensitive to antibiotics Researchers have discovered a new way to reverse antibiotic resistance in some bacteria using hydrogen sulfide (H2S).This is a very exciting discovery because for the first time it 's shown that H2S can, in fact, improve sensitivity to antibiotics, and even reverse antibiotic resistance in bacteria that do not naturally produce the agent.While the study focused on the effects of exogenous H2S on A. baumannii, the scientists believe the results will be mimicked in all bacteria that do not naturally produce H2S.--Cadmium levels in waste pickers ‘four times higher’

Buffer could limit environmental spread of antibiotic resistance
Many livestock receive antibiotics that protect against bacterial diseases. But over time, antibiotics also trigger the evolution of bacteria that can resist them. Those antibiotic-resistant bacteria, in turn, can pass along genes responsible for that resistance to other bacterial species, ultimately reducing the effectiveness of the drugs
When manure from livestock administered with antibiotics is applied as fertilizer, antibiotic resistance genes can enter soil and, following precipitation, run off into rivers and other bodies of water, furthering their spread.
A research team ran experiments to evaluate the minimum distance between a manure slurry-covered field and surface water that would prevent the runoff of antibiotics and antibiotic resistance genes. The team found that levels of all three antibiotics it measured, along with seven of the 10 resistance genes, substantially decreased as that distance increased.
The researchers concluded that maintaining between 112 and 220 feet of distance would limit most runoff pollution across a no-till field rich in the clay soils .
Because that recommended distance is specific to the experimental site, the team recommended running similar experiments with varying field conditions, soil types, slopes and rainfall amounts to calibrate suitable distances elsewhere.

Gulls pay attention to human eyes
Herring gulls notice where approaching humans are looking, and flee sooner when they're being watched, a new study shows.
Researchers approached gulls while either looking at the ground or directly at the birds.
Gulls were slower to move away when not being watched—allowing a human to get two metres closer on average.
Newly fledged gulls were just as likely to react to human gaze direction as older birds, suggesting they are born with this tendency or quickly learn it.

MRI scans show brain reorganization during long space flights, but no neurodegeneration
An international team of researchers has found that long space flights can lead to some minor brain reorganization but no neurodegeneration.
The group describes their study of the brains of cosmonauts returning from long-term missions aboard the International Space Station, and what they found.
The researchers found that the brain reorients itself during long space missions, essentially floating into different parts of the skull. This resulted in slight reorganization of the brain itself in response to the reorientation. The cosmonauts brains also responded in other ways to the unusual living environment—they acquired new motor skills and had better balance and coordination. The researchers also found that the reorientation did not result in neurodegeneration and that normal orientation was nearly restored seven months after the cosmonauts returned to Earth. They also confirmed fluid build-up behind the eyes as the reason for the loss of visual acuity during long space flights.

Alternative leather from fungi
https://phys.org/news/2019-12-alternative-leather-fungi.html
Animal skin is an excellent material, but the tanning process of leather causes significant chromium emissions that are damaging to the environment and human health. Synthetic leathers also burden the environment and fail to match the quality and durability of animal leather. Therefore, new bio-based replacement materials are sought for leather. Researchers now are using fungal mycelium to produce skinlike material that would be suited for industrial production.
For centuries, fungi and polypores have been used for making skinlike fabrics and accessories in Europe. Designers and researchers are now reviving this tradition to find sustainable alternatives to replace leather.
Scientists have been studying fungi and other microbes and their use in industrial biotechnology for quite a while. In laboratory conditions, fungal mycelium can be used to rapidly produce skinlike material with quite similar feel and tensile strength as animal skin.
Some items made of fungus-based leather are already being produced for commercial markets.
The production process of fungus-based leather represents creativity at its best: organic waste can be used as raw material for synthetic leather. Fungal mycelium can produce skinlike material out of, for example, food waste.

How stone forests get their spikes
Stone forests—pointed rock formations resembling trees that populate regions of China, Madagascar, and many other locations worldwide—are as majestic as they are mysterious, created by uncertain forces that give them their shape.
A team of scientists has now shed new light on how these natural structures are created. Through a series of simulations and experiments, they show how flowing water carves ultra-sharp spikes in landforms. In their study, the scientists simulated the formation of these pinnacles over time through a mathematical model and computer simulations that took into account how dissolving produces flows and how these flows also affect dissolving and thus reshaping of a formation.
To confirm the validity of their simulations, the researchers conducted a series of experiments in NYU's Applied Mathematics Lab. Here, the scientists replicated the formation of these natural structures by creating sugar-based pinnacles, mimicking soluble rocks that compose karst and similar topographies, and submerging them in tanks of water. Interestingly, no flows had to be imposed, since the dissolving process itself created the flow patterns needed to carve spikes.
The experimental results reflected those of the simulations, thereby supporting the accuracy of the researchers' model (see "Video2ExperimentSimulation" in the below drive). The authors speculate that these same events happen—albeit far more slowly—when minerals are submerged under water, which later recedes to reveal stone pinnacles and stone forests.
