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!"

Physicists have demonstrated an atomically thin, intelligent quantum sensor that can simultaneously detect all the fundamental properties of an incoming light wave.
The research, published April 13 in the journal Nature, demonstrates a new concept based on quantum geometry that could find use in health care, deep-space exploration and remote-sensing applications.
Typically, when you want to characterize a wave of light, you have to use different instruments to gather information, such as the intensity, wavelength and polarization state of the light. Those instruments are bulky and can occupy a significant area on an optical table. Now we have a single device—just a tiny and thin chip—that can determine all these properties simultaneously in a very short time.
The device exploits the unique physical properties of a novel family of two-dimensional materials called moiré metamaterials. The 2D materials have periodic structures and are atomically thin. If two layers of such a material are overlaid with a small rotational twist, a moiré pattern with an emergent, orders-of-magnitude larger periodicity can form. The resulting moiré metamaterial yields electronic properties that differ significantly from those exhibited by a single layer alone or by two naturally aligned layers.
The sensing device that physicists now chose to demonstrate their new idea incorporates two layers of relatively twisted, naturally occurring bilayer graphene, for a total of four atomic layers.

The natural world possesses its own intrinsic electrical grid composed of a global web of tiny bacteria-generated nanowires in the soil and oceans that "breathe" by exhaling excess electrons.
In a new study, researchers discovered that light is a surprising ally in fostering this electronic activity within biofilm bacteria. Exposing bacteria-produced nanowires to light, they found, yielded an up to a 100-fold increase in electrical conductivity.
The dramatic current increases in nanowires exposed to light show a stable and robust photocurrent that persists for hours.
The results could provide new insights as scientists pursue ways to exploit this hidden electrical current for a variety of purposes, from eliminating biohazard waste and creating new renewable fuel sources.
Almost all living things breathe oxygen to get rid of excess electrons when converting nutrients into energy. Without access to oxygen, however, soil bacteria living deep under oceans or buried underground over billions of years have developed a way to respire by "breathing minerals," like snorkeling, through tiny protein filaments called nanowires.
When bacteria were exposed to light, the increase in electrical current surprised researchers because most of the bacteria tested exist deep in the soil, far from the reach of light. Previous studies had shown that when exposed to light nanowire-producing bacteria grew faster.
In the new study researchers concluded that a metal-containing protein known as cytochrome OmcS—which makes up bacterial nanowires—acts as a natural photoconductor: the nanowires greatly facilitate electron transfer when biofilms are exposed to light.
It is a completely different form of photosynthesis. Here, light is accelerating breathing by bacteria due to rapid electron transfer between nanowires.
Researchers are exploring how this insight into bacterial electrical conductivity could be used to spur growth in optoelectronics—a subfield of photonics that studies devices and systems that find and control light—and capture methane, a greenhouse gas known to be a significant contributor to global climate change.

Physicists discover new rule for orbital formation in chemical reactions
Squeaky, cloudy or spherical—electron orbitals show where and how electrons move around atomic nuclei and molecules. In modern chemistry and physics, they have proven to be a useful model for quantum mechanical description and prediction of chemical reactions. Only if the orbitals match in space and energy can they be combined—this is what happens when two substances react with each other chemically. In addition, there is another condition that must be met, as researchers have now discovered: The course of chemical reactions also appears to be dependent on the orbital distribution in momentum space. The results were published in the journal Nature Communications.

Some species of tardigrades, or water bears as the tiny aquatic creatures are also known, can survive in different environments often hostile or even fatal to most forms of life. For the first time, researchers describe a new mechanism that explains how some tardigrades can endure extreme dehydration without dying. They explored proteins that form a gel during cellular dehydration. This gel stiffens to support and protect the cells from mechanical stress that would otherwise kill them. These proteins have also been shown to work in insect cells and even show limited functionality in human cultured cells.

A new system capable of reading lips with remarkable accuracy even when speakers are wearing face masks could help create a new generation of hearing aids.
Researchers have discovered a previously unknown bacteria-killing toxin that could pave the way for a new generation of antibiotics.
The study shows that the bacterial pathogen Pseudomonas aeruginosa, known to cause hospital-acquired infections such as pneumonia, secretes a toxin that has evolved to kill other species of bacteria.
The key aspect of his discovery is not just that this toxin kills bacteria, but how it does so.This research is significant, because it shows that the toxin targets essential RNA molecules of other bacteria, effectively rendering them non-functional. It's a total assault on the cell because of how many essential pathways depend on functional RNAs. This toxin enters its target, hijacks an essential molecule needed for life, and then uses that molecule to disrupt normal processes.
Researchers say that this development holds great potential for future research that could eventually lead to new innovations that combat infection-causing bacteria.
They think the newly-discovered vulnerability can be exploited for future antibiotic development.

Watch this special Space Sparks episode to learn more about the stellar nursery called 30 Doradus, as captured by the NASA/ESA/CSA James Webb Space Telescope.
In a first, scientists have captured on video all the steps a virus follows as it enters and infects a living cell in real time and in three dimensions.
Scientists achieved the feat by using advanced imaging called lattice light sheet microscopy as well as chemical and genetic manipulation.
The first part of the video shown here follows a virus engineered to sprout SARS-CoV-2 spike proteins (labeled pink) as it is captured at a cell surface and engulfed by a cellular compartment called an endosome. The virus then fuses with the endosome membrane and injects its genetic material (labeled blue) inside the cell—the steps necessary to kick off a cycle of viral infection and replication.
The second part of the video shows many such viruses inside the cell. The video covers 4 minutes of activity, with snapshots taken every 4 seconds.
The findings, published Sept. 1 in PNAS, provide new insights into the fundamental mechanics of viral infection and could point the way to new methods for intervening before the onset of COVID-19.
The researchers' work reveals that viruses can't fuse with the membrane and release their genomes unless they're bathed in a slightly acidic environment. Experiments indicated that the pH must fall between 6.2 and 6.8, just shy of neutral and on par with bodily fluids such as saliva and urine. Endosomes have such acidity, and the team's measurements confirmed that this is also the pH range inside a typical human nose, where SARS-CoV-2 infection often begins.

The ability to better monitor the pest and make predictions about where it will appear could help farmers control the pest more effectively, which would reduce the financial and environmental impacts of pesticide use. -- Bees use patterns, not just colors, to find flowersHoneybees rely heavily on flower patterns—not just colors—when searching for food, new research shows. |
Astronomers report the detection of a new polar ring galaxy using the data obtained with the Subaru Telescope as part of the Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP).
The so-called polar ring galaxies (PRGs) are systems composed of an S0-like galaxy and a polar ring, which remain separate for billions of years. In general, these outer polar rings, composed of gas and stars, are aligned roughly in a perpendicular orientation with respect to the major axis of the central host galaxy.
However, although more than 400 PRG candidates have been discovered to date, only dozens of them have been confirmed as real polar ring galaxies by follow-up spectroscopic observations.
