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!"
"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!

Scientists 'film' a quantum measurement. Measuring a quantum system causes it to change—one of the strange but fundamental aspects of quantum mechanics. Researchers now have now been able to demonstrate how this change happens.

Hundreds of bird species in India are in decline, according to the country’s first major report on the state of bird populations. Birds of prey and waterbirds seem to have been hit particularly hard owing to habitat destruction, hunting and the pet trade.
But it’s not all bad news. Species such as the house sparrow seem to be doing better than previously thought.
The State of India’s Birds report, released on 17 February, relied on more than 10 million observations from birdwatchers recorded in the online repository of worldwide bird sightings, eBird.
The report’s authors — researchers from 10 government and non-profit research and conservation groups — used eBird data to analyse long-term trends for 261 bird species. That is, the proportional change in the frequency of reported sightings of since 1993. They found that more than half of those species have declined since 2000. The group also looked at the current annual trends in 146 species; nearly 80% have declined in the past 5 years.
The researchers classified 101 species as of high conservation concern, and another 319 species as of moderate conservation concern, on the basis of declines in their abundance and range, and their status on the International Union for Conservation of Nature’s Red List.

Arms race between bacteria and viruses: New light
A new study reveals how bacterial immune systems can be harmful for their hosts, and why they are not found in all bacteria.
The existing CRISPR anti-viral immunity was often a disadvantage to the bacterium when infected by certain viruses.
CRISPR has become well known for its repurposing as a tool for precise genetic engineering. However, CRISPR systems (segments of DNA) naturally occur in many bacteria and have the important function of providing bacteria with immunity against viruses or foreign DNA.
This triggered a major question as to whether autominnunity is important in other bacterial pathogens.
Triggering the powerful CRISPR defence systems is risky for a bacterium. "Importantly, this may help answer a long-standing question of why these defence systems are absent in 60 per cent of bacteria."
For example, Staphylococcus aureus pathogens that often take up extra genes to become multidrug resistant, seldom have CRISPR defence. An example of this is MRSA (Methicillin-resistant Staphylococcus aureus) an infection often occurring in people who have been in hospitals or other healthcare settings like residential care homes, which has become resistant to many of the antibiotics used to treat ordinary staph infections. It seldom has CRISPR defence.

Henneguya salminicola: Microscopic parasite has no mitochondrial DNA
An international team of researchers has found a multicellular animal with no mitochondrial DNA, making it the only known animal to exist without the need to breathe oxygen. In their paper published in Proceedings of the National Academy of Sciences, the group describes their study of Henneguya salminicola, a microscopic, parasitic member of the group Myxozoa and its unique physiology.
One of the common characteristics of all multicellular animals on Earth is mitochondrial respiration—the process by which oxygen is used to generate adenosine triphosphate—the fuel used to power cellular processes. The process takes place in mitochondria, which has both its own genome and the main genome found in the rest of the body's cells. But now, there is a known exception: Henneguya salminicola.
H. salminicola is a microscopic parasite that infects salmon. When the host dies, spores are released that are consumed by worms, which can also serve as hosts for the parasite. When salmon eat the worms, they become infected as the parasite moves into their muscles. They can be seen by fishermen as white, oozing bubbles, which is why salmon with H. salminicola infections are sometimes said to have tapioca disease.
In their work, the researchers sequenced the DNA of H. salminicola tissue and found no mitochondrial DNA at all. Believing they had made an error, the team repeated their work and once again found no sign of mitochondrial DNA. Confused, they sequenced the DNA of close relatives of H. salminicola and found evidence of the expected mitochondrial genomes. H. salminicola did have structures that resembled mitochondria but they were not capable of producing the enzymes needed for respiration, a finding that suggested the creature was capable of surviving without oxygen—a first. The presence of structures that resemble mitochondrial DNA suggests that the tiny parasites have undergone a process of de-evolution. In addition to losing the apparatus to create ATP, they also have lost tissue, nerve cells and muscles.
The researchers did not find any other mechanism for producing the fuel cells in H. salminicola would need to survive, but suggest they likely steal energy from their host using some type of proteins.

Line of defense: Scientists report surprising evolutionary shift in snakes
https://phys.org/news/2020-02-line-defense-scientists-evolutionary-...
In the animal kingdom, survival essentially boils down to eat or be eaten. How organisms accomplish the former and avoid the latter reveals a clever array of defense mechanisms. Maybe you can outrun your prey. Perhaps you sport an undetectable disguise. Or maybe you develop a death-defying resistance to your prey's heart-stopping defensive chemicals that you can store in your own body to protect you from predators.
Species of the Rhabdophis genus. Commonly called "keelbacks" and found primarily in southeast Asia, the snakes sport glands in their skin, sometimes just around the neck, where they store bufadienolides, a class of lethal steroids they get from toads, their toxic prey of choice.
"These snakes bend their necks in a defensive posture that surprises unlucky predators with a mouthful of toxins"."Scientists once thought these snakes produced their own toxins, but learned, instead, they obtain it from their food—namely, toads."
In a surprising twist, the researchers discovered not all members of the genus derive their defensive toxin from the same source. A species group of the snakes, found in western China and Japan, shifted its primary diet from frogs (including toads) to earthworms.
The earthworms don't produce the toxins; instead, the snakes also snack on firefly larvae, which produce the same class of toxins as the toads. Their findings appear in the Feb. 24, 2020, early online issue of the Proceedings of the National Academy of Sciences. This is the first documented case of a vertebrate predator switching from a vertebrate prey to an invertebrate prey for the selective advantage of getting the same chemical class of defensive toxin.

Study on artificial and biological neural networks found that the use of contrived experimental manipulations with the hope of uncovering simple rules or representations is unlikely to yield models that can be effectively applied to the real world.
Models based on artificial neural networks do not learn rules or representations of the world around them that are easy for humans to interpret. On the contrary, they typically use local computations to analyze different aspects of data in a high-dimensional parameter space.
