     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".

"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!

How cholesterol plays a part in the life cycle process and death

For all their uncanny intelligence and seemingly supernatural abilities to change color and regenerate limbs, octopuses often suffer a tragic death. After a mother octopus lays a clutch of eggs, she quits eating and wastes away; by the time the eggs hatch, she is dead. Some females in captivity even seem to speed up this process intentionally, mutilating themselves and twisting their arms into a tangled mess.

The source of this bizarre maternal behavior seems to be the optic gland, an organ similar to the pituitary  in mammals. For years, just how this gland triggered the gruesome death spiral was unclear, but a new study by researchers 

shows that the optic gland in maternal octopuses undergoes a massive shift in cholesterol metabolism, resulting in dramatic changes in the steroid hormones produced. Alterations in cholesterol metabolism in other animals, including humans, can have serious consequences on longevity and behavior, and the study's authors believe this reveals important similarities in the functions of these steroids across the animal kingdom, in soft-bodied cephalopods and vertebrates alike.

Cholesterol is important from a dietary perspective, and within different signaling systems in the body too. It's involved in everything from the flexibility of cell membranes to production of stress hormones, but it was a big surprise to see it play a part in this life cycle process as well.

In 1977, Brandeis University psychologist Jerome Wodinsky showed that if he removed the optic gland from Caribbean two-spot octopus (Octopus hummelincki) mothers, they abandoned their clutch of eggs, resumed feeding, and lived for months longer. At the time, cephalopod biologists concluded that the optic gland must secrete some kind of "self-destruct" hormone, but just what it was and how it worked was unclear.

Scientists transform beating heart stem cells into brain cells

By turning off a single gene,  researchers  caused stem cells already becoming heart cells to change course and become future brain cells. And that could help scientists understand how specific genes affect the development of your body and the role they play in developmental diseases, potentially leading to new therapies.

Previously, it’s been thought that the paths that cells take towards becoming a heart cell or a nerve cell are very rigid. This study is showing that this process is actually much more fluid.

Stem cells are kind of a blank slate. They’re “pluripotent,” meaning that they can transform into any type of cell in the body. There are a series of steps involved in this transformation process, called canalization. Until now, it was thought that once stem cells start undergoing canalization, they can’t change course to become other, different cell types.

Scientists now used CRISPR genome-editing approaches to turn off the Brm gene in mouse stem cells undergoing canalization into heart cells. This resulted in the mouse cells lacking a protein called Brahma.

Turning off Brm prevented stem cells from becoming beating heart cells. Additionally, they had switched from being heart precursors to become precursors for brain cells.

This study was the first to explore the effect of Brahma on cardiac differentiation

A nontoxic glue for plywood—from glucose, citric acid

The go-to materials for building home furniture, décor and floors are composite wood products that come in large sheets. But the glues and resins holding together particleboard, fiberboard and plywood usually contain formaldehyde and could release this probable carcinogen into the air. To develop a nontoxic adhesive, researchers reporting in ACS Applied Materials & Interfaces have combined glucose and citric acid—sugar and an orange juice ingredient—into a strong, water-resistant wood glue for plywood.

Magnetism is a collective phenomenon in which the electrons in a material all spin in the same direction. An everyday example is the ferromagnet, which owes its magnetic properties to the alignment of spins. Neighboring electrons can also spin in opposite directions. In this case, the spins still have well-defined directions but there is no magnetization. Frustrated magnets are frustrated because the neighboring electrons try to orient their spins in opposing directions, and when they find themselves in a triangular lattice, they can no longer settle on a common, stable arrangement. The result: a frustrated magnet.

Unusual quantum state of matter observed for the first time

It's not every day that someone comes across a new state of matter in quantum physics. Yet this is exactly what an international team of physicists has done recently. 

In a recent article published in the scientific journal Physical Review X, the researchers document a "quantum spin liquid ground state" in a magnetic material created in  lab: Ce2Zr2O7, a compound composed of cerium, zirconium and oxygen.

In , spin is an internal property of electrons linked to their rotation. It is spin that gives the material in a magnet its magnetic properties.

In some materials, spin results in a disorganized structure similar to that of molecules in a liquid, hence the expression "spin liquid."

In general, a material becomes more disorganized as its temperature rises. This is the case, for example, when water turns into steam. But the principal characteristic of spin liquids is that they remain disorganized even when cooled to as low as absolute zero (–273°C).

Spin liquids remain disorganized because the direction of spin continues to fluctuate as the material is cooled instead of stabilizing in a solid state, as it does in a conventional magnet, in which all the spins are aligned.

Imagine an electron as a tiny compass that points either up or down. In conventional magnets, the electron spins are all oriented in the same direction, up or down, creating what is known as a "ferromagnetic phase." This is what keeps photos and notes pinned to your fridge.

But in quantum spin liquids, the electrons are positioned in a triangular lattice and form a "ménage à trois" characterized by intense turbulence that interferes with their order. The result is an entangled wave function and no magnetic order.

When a third electron is added, the electron spins cannot align because the two neighboring electrons must always have opposing spins, creating what we call magnetic frustration.

This generates excitations that maintain the disorder of spins and therefore the liquid state, even at very low temperatures."

So how did they add a third electron and cause such frustration?

Enter the frustrated magnet Ce2Zr2O7 created by physicists in a  lab. 

Ce2Zr2O7 is a cerium-based material with magnetic properties. The existence of this compound was known. This new breakthrough was creating it in a uniquely pure form. They used samples melted in an optical furnace to produce a near-perfect triangular arrangement of atoms and then checked the quantum state.

It was this near-perfect triangle that enabled this team  to create magnetic frustration in Ce2Zr2O7.

Their  measurements showed an overlapping particle function—therefore no Bragg peaks—a clear sign of the absence of classical magnetic order. They also observed a distribution of spins with continuously fluctuating directions, which is characteristic of spin liquids and magnetic frustration. This indicates that the material they created behaves like a true spin liquid at low temperatures.

After corroborating these observations with computer simulations, the team concluded that they were indeed witnessing a never-before-seen quantum state.

Distantly related mushrooms gained the ability to make toxin via horizontal gene transfer
A team of researchers affiliated with several institutions in China and the U.S. has found evidence that suggests three distantly related types of mushrooms gained their ability to produce a dangerous toxin via horizontal gene transfer sometime in their past. In their paper published in Proceedings of the National Academy of Sciences, the group describes their genetic analysis of multiple species of mushrooms to determine which genes in three particular species were responsible for producing the same toxin and what it showed them about its origins.

Scientists have known for some time that the three mushrooms—the deadly dapperling, the destroying angel and the funeral bell—are not only toxic, but also have an identical . Some scientists assumed they must have a common ancestor, but the researchers in this new effort suspected something else was afoot because the three  are so distantly related. To get to the bottom of the matter, they obtained samples of the three mushrooms along with samples from 12 others.

To find out which part of their genome was responsible for making the toxins, the researchers sequenced all of their samples. They found two  that were responsible for creating the toxins and were identical in all three species. A closer look at the genes showed that they were, indeed, distantly related, but it also showed that the genes responsible for producing the toxins were not passed down from a . That left just one other possibility—sometime in their past, all three had received a  from another, possibly extinct, mushroom.

A horizontal gene transfer occurs when a third party, such as a bacterium, absorbs some of the genome of a host it is infecting and then passes those cells into another host that it infects. The researchers note that horizontal gene transfer is common with bacteria. In many cases, they steal bits of host DNA, add it to their own, and then pass it on to their offspring. Those offspring can then add the new DNA to cells they infect in another host.

Only 3% of potential bacterial drug sources known
The emergence of antibiotic-resistant pathogens and the increasing difficulty in developing new drugs has contributed to global challenges in combating infectious diseases. An extensive bioinformatics survey of around 170,000 bacterial genomes indicates that only three percent of the genomic potential for microbial natural products—chemically diverse bacterial metabolites that form the basis of antibiotic drugs—have been discovered so far. Co-led by Prof Nadine Ziemert of the German Center for Infection Research (DZIF), the survey identified several bacterial genera as producers of highly diverse natural products that could help to overcome the bottleneck in drug development.

Bacterial producers of  as sources of drugs such as antibiotics have been studied for decades. However, the rate of new drug discovery has stagnated in recent years. There is uncertainty on how much chemical diversity exists in nature and how many new compounds can still be discovered. Additionally, assumptions that a large portion of natural product-producers and respective biosynthetic pathways have been discovered already have not been investigated.

To understand the true potential of useful biosynthetic pathways and natural products in the bacterial world, an international team of researchers from Germany, the Netherlands and the United States surveyed a large amount of genomic data—around 170,000 bacterial genomes and several thousands of so-called Metagenome Assembled Genomes representing individual microbial taxa from diverse environments. Using a  mining strategy, the team identified so-called Biosynthetic Gene Clusters (BGCs)—clusters of genes in  that jointly encode the biosynthesis pathways of natural products. Grouping the BGCs into gene cluster families according to similarity, the researchers developed tools that allow the study of the biosynthetic diversity represented in the bacterial genome database.

This bioinformatics genome mining approach reveals that only three percent or even less of the genomic potential for the production of natural products has been discovered so far.

Based on the mined data, the researchers identified bacterial taxa that showed high biosynthetic potential, among them multiple unexplored taxonomic groups.

What is watermelon snow?

Otherwise known as glacier blood, watermelon snow is found worldwide in mountains and polar regions. The pink-red snow has a faintly fruity smell but is reported to have laxative effects if eaten.

The watermelon colour comes from freshwater green algae called Chlamydomonas nivalis. In summer, the algae produce a red pigment to protect themselves from the Sun’s intense rays. This pigment belongs to a large group of carotenoid substances, many of which are found in brightly coloured fruits and vegetables such as tomatoes and carrots.

Unfortunately, the pigment reduces snow’s ability to reflect heat, leading to faster melting rates.
