         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!"

Radiation can slow corrosion of some materials

Radiation nearly always degrades the materials exposed to it, hastening their deterioration and requiring replacement of key components in high-radiation environments such as nuclear reactors. But for certain alloys that could be used in fission or fusion reactors, the opposite turns out to be true: Researchers have now found that instead of hastening the material's degradation, radiation actually improves its resistance, potentially doubling the material's useful lifetime.

The finding could be a boon for some new, cutting-edge reactor designs, including molten-salt-cooled fission reactors, and new fusion reactors such as the ARC.

Researchers  repeated it dozens of times, with different conditions and every time they got the same results showing delayed corrosion.

The kind of reactor environment the team simulated in their experiments involves the use of molten sodium, lithium, and potassium salt as a coolant for both the nuclear fuel rods in a fission reactor and the vacuum vessel surrounding a superhot, swirling plasma in a future fusion reactor. Where the hot molten salt is in contact with the metal, corrosion can take place rapidly, but with these nickel-chromium alloys they found that the corrosion took twice as long to develop when the material was bathed in radiation from a proton accelerator, producing a radiation environment similar to what would be found in the proposed reactors.

Careful analysis of images of the affected alloy surfaces using transmission electron microscopy, after irradiating the metal in contact with molten salt at 650 degrees Celsius, (a typical operating temperature for salt in such reactors), helped to reveal the mechanism causing the unexpected effect. The radiation tends to create more tiny defects in the structure of the alloy, and these defects allow atoms of the metal to diffuse more easily, flowing in to quickly fill the voids that get created by the corrosive salt. In effect, the radiation damage promotes a sort of self-healing mechanism within the metal.

Rock-breathing bacteria are electron spin doctors, study shows

**Electrons spin. It's a fundamental part of their existence. Some spin "up" while others spin "down." Scientists have known this for about a century, thanks to quantum physics.

They've also known that magnetic fields can affect the direction of an electron's quantum spin, flipping it from up to down and vice versa. And it doesn't take much: Even a bacterial cell can do it.

Researchers  have found that protein "wires" connecting a bacterial cell to a solid surface tend to transmit electrons with a particular spin.

This ability to select an electron's quantum spin could have implications for the use of bacteria in the biotechnology industry and in burgeoning efforts to create bacteria-based energy cells, as well as future electronic technologies.

 Scientists have been studying certain bacteria that can use solid surfaces in the same way animals use oxygen to breathe. Instead of dumping electrons generated during metabolism onto inhaled oxygen molecules, the bacteria send the electrons down specialized proteins that plug into an external surface.

Unlike most organisms that are able to use oxygen as the electron acceptor. These bacteria transfer the electrons to a solid mineral or, as they do in our lab, to electrodes that are outside the cell.

In terms of metabolism, they "breathe" the minerals or electrodes.

To reach the external surface, the electrons are shuttled through various protein molecules that form electrical conduits. These proteins have magnetic fields that can favor a particular spin as the electrons shuttle through.

Scientists found that these magnetic fields are affected by a characteristic of the proteins called "chirality."

Many molecules, especially biological molecules, appear in two versions, each a mirror image of the other. Scientists call this "chirality." It's similar to human hands. Left and right hands have four fingers and a thumb, but they're not exactly the same. They're both hands, but they're mirror images of each other, oriented in opposite directions. Molecules can be the same way, and in fact, scientists refer to chiral molecules as being either left-handed or right-handed.

The left- or right-handedness of a protein may affect the polarity of the magnetic fields experienced by the electrons as they shuttle through the protein. That's what happens to those electrons that travel along a protein wire to get to the outside of a rock-breathing bacterium.

 These "rock-breathing" bacteria one day might be used to produce sustainable energy, for years. Finding that the electron-conducting proteins in these bacteria can select for a particular electron spin based on their chirality could be useful in developing certain electronic devices called "spintronics" . Spintronics use not only the charge of electrons but also their quantum spin and may be especially useful in quantum computing.

This work shows that bacterial cytochromes may be interesting candidates for spintronics."

Study finds fatty acid that kills cancer cells

Researchers have demonstrated that a fatty acid called dihomogamma-linolenic acid, or DGLA, can kill human cancer cells. The study found that DGLA can induce ferroptosis in an animal model and in actual human cancer cells. Ferroptosis is an iron-dependent type of cell death that was discovered in recent years and has become a focal point for disease research as it is closely related to many disease processes.

Implications of this work: If you could deliver DGLA precisely to a cancer cell, it could promote ferroptosis and lead to tumor cell death. Also, just knowing that this fat promotes ferroptosis might also affect how we think about conditions such as kidney disease and neurodegeneration where we want to prevent this type of cell death.

DGLA is a polyunsaturated fatty acid found in small amounts in the human body, though rarely in the human diet. 

It was discovered that feeding nematodes ( Caenorhabditis elegans ) a diet of DGLA-laden bacteria killed all the germ cells in the worms as well as the stem cells that make the germ cells. The way the cells died carried many signs of ferroptosis.

Researchers also showed that DGLA could induce ferroptosis in human cancer cells. They also found an interaction with another fatty acid class, called an ether lipid, that had a protective effect against DGLA. When they took out the ether lipids, the cells died faster in the presence of DGLA. The study also demonstrated that C. elegans can be a useful animal research model in the study of ferroptosis, a field that has had to rely mostly on cell cultures.

Plant communication:Detection of electrical signaling between tomato plants raises interesting questions

Plants can communicate with other plants using wireless pathways above and underground.  Some examples of these underground communication pathways are: (1) mycorrhizal networks in the soil; (2) the plants’ rhizosphere; (3) acoustic communication; (4) naturally grafting of roots of the same species; (5) signaling chemicals exchange between roots of plants; and (6) electrical signal transmission between plants through the soil. 

Plants have developed complex systems of communication. Electrical, mechanical, and chemical signals induced by above-ground stresses in plants can affect below ground communication between roots of neighboring plants. There are different electrical, chemical and electrochemical pathways for underground signaling between plants. Electrical signal transmission is fast in comparison with chemical signaling which is controlled by a slow diffusion. Electrostimulation of plants induces electrotonic potentials transmission in the electro-stimulated plants as well as the neighboring plants located in different pots regardless if plants are the same or different types.

The soil beneath our feet is alive with electrical signals being sent from one plant to another, according to new research. A paper published recently  used physical experiments and mathematical modeling to study transmission of electrical signals between tomato plants. It was found that electrical signal propagation within a plant and also between plants through a network of Mycorrhizal fungi that's ubiquitous in soil appears to act as circuitry.

Plants generate electric signals that propagate through their parts. When the roots of tomatoes are experimentally isolated from each other with an air gap, the electrical impedance of the gap is very large.

"The electrical signals won't go through this gap. However, when the plants are living in common soil, experiments conducted  found that the ground impedance is not very large and they can communicate by passing electrical signals to each other through the Mycorrhizal network in the soil.

The tomato research, which focused on experimental study and mathematical modeling of electrical signal propagation between plants of the same species, opens new doors to questions about whether plants communicate across species through fungi. The soil plays the role of a conductor.

Another issue is to study the plants' communications via electric waves through the air.

Reducing noise transmitted through an open window

A new device that can reduce the intensity of sound passing through open windows is presented in a proof-of-principle study in Scientific Reports. It fits into a two-panel sliding window and can decrease the perceived loudness of urban transportation noises by up to half (10 decibel reduction).

The device, assembled by Bhan Lam and colleagues, consists of 24 loudspeakers (each 4.5 cm in diameter), fixed in a  to bars attached to the inside of a window and one sensor located outside the window. If the sensor detects noise outside the building, the loudspeakers emit "anti-noise" at the same frequency as the detected noise but with inverted . This "anti-noise" cancels out the detected noise and reduces the volume of noise pollution entering the room, even when the window is open.
