     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!

Discovery of a new mass extinction

It's not often a new mass extinction is identified; after all, such events were so devastating they really stand out in the fossil record. In a new paper, published today in Science Advances, an international team has identified a major extinction of life 233 million years ago that triggered the dinosaur takeover of the world. The crisis has been called the Carnian Pluvial Episode.

The cause was most likely massive volcanic eruptions in the Wrangellia Province of western Canada, where huge volumes of volcanic basalt was poured out and forms much of the western coast of North America.

Native stinging tree toxins match the pain of spiders and scorpions

The painful toxins wielded by a giant  stinging tree are surprisingly similar to the venom found in spiders and cone snails researchers have found.

The Gympie-Gympie stinging tree is one of the world's most venomous plants and causes extreme long-lasting pain. Researchers found a new family of toxins, which they've named 'gympietides' after the Gympie-Gympie stinging tree.

The tree's scientific name is Dendrocnide which literally means 'stinging tree'—a member of the nettle family. Like other stinging plants such as nettles, the giant stinging tree is covered in needle-like appendages called trichomes that are around five millimetres in length—the trichomes look like fine hairs, but actually act like hypodermic needles that inject toxins when they make contact with skin.

 Small molecules in the trichomes such as histamine, acetylcholine and formic acid have been tested but injecting these does not cause the severe and long-lasting pain of the stinging tree, suggesting that there was an unidentified neurotoxin to be found.

Although they come from a plant, the gympietides are similar to spider and cone snail toxins in the way they fold into their 3-D molecular structures and target the same pain receptors—this arguably makes the Gympie-Gympie tree a truly "venomous" plant. The long-lasting pain from the stinging tree may be explained by the gympietides permanently changing the sodium channels in the sensory neurons, not due to the fine hairs getting stuck in the skin.

By understanding how this toxin works, scientists hope to provide better treatment to those who have been stung by the plant, to ease or eliminate the pain.

With these toxins from both plants and animals having a shared method of causing pain, it begs the question, when and how did these toxins evolve?

The researchers point to two possibilities for the toxin's evolution from either an ancestral gene in an ancient shared ancestor or convergent evolution, where nature re-invents the most fitting structure to fit a common purpose.

How Dantu Blood Group protects against malaria—and how all humans could benefit

In 2017, researchers discovered that the rare Dantu blood variant, which is found regularly only in parts of East Africa, provides some degree of protection against severe malaria.

The secret of how the Dantu genetic blood variant helps to protect against malaria has been revealed for the first time by scientists now. They found that red blood cells in people with the rare Dantu blood variant have a higher surface tension that prevents them from being invaded by the world's deadliest malaria parasite, Plasmodium falciparum.

Analysis of the characteristics of the red blood cell samples indicated that the Dantu variant created cells with a higher surface tension—like a drum with a tighter skin. At a certain tension, malaria parasites were no longer able to enter the cell, halting their lifecycle and preventing their ability to multiply in the blood. The Dantu blood group has a novel 'chimeric' protein that is expressed on the surface of red blood cells, and alters the balance of other surface proteins.

This finding could also be significant in the wider battle against malaria. Because the surface tension of human red blood  cells increases as they age, it may be possible to design drugs that imitate this natural process to prevent malaria infection or reduce its severity.

Harnessing DNA molecules for disease detection and electronics

DNA molecules express heredity through genetic information. However, in the past few years, scientists have discovered that DNA can conduct electrical currents. This makes it an interesting candidate for roles that nature did not intend for this molecule, such as smaller, faster and cheaper electric circuits in electronic devices, and to detect the early stages of diseases like cancer and COVID-19.

The  most surprising recent finding was that the current passes through the DNA backbone, contrary to prior assumptions in the scientific community that the current flowed along DNA base pairs.

Human white blood cells use molecular paddles to swim

Human white blood cells, known as leukocytes, swim using a newly described mechanism called molecular paddling, researchers report

This microswimming mechanism could explain how both immune cells and cancer cells migrate in various fluid-filled niches in the body, for good or for harm.

Cells have evolved different strategies to migrate and explore their environment. For example, , microalgae, and bacteria can swim through shape deformations or by using a whip-like appendage called a flagellum. By contrast, somatic mammalian cells are known to migrate by attaching to surfaces and crawling. It is widely accepted that leukocytes cannot migrate on 2-D surfaces without adhering to them.

A prior study reported that certain human white blood cells called neutrophils could swim, but no mechanism was demonstrated. Another study showed that mouse leukocytes could be artificially provoked to swim. It is widely thought that cell swimming without a flagellum requires changes in cell shape, but the precise mechanisms underlying leukocyte migration have been debated.

This new study provide experimental and computational evidence  that human leukocytes can migrate on 2-D surfaces without sticking to them and can swim using a mechanism that does not rely on changes in cell shape. The cells paddle using transmembrane proteins, which span the cell membrane and protrude outside the cell. The researchers show that membrane treadmilling—rearward movement of the cell surface—propels leukocyte migration in solid or liquid environments, with and without adhesion.

Ocean algae get 'coup de grace' from viruses

Scientists thought till now that ocean viruses always quickly kill algae, but new research now shows they live in harmony with algae and viruses provide a "coup de grace" (a final blow or shot given to kill a wounded person or animal) only when blooms of algae are already stressed and dying.
This new finding will likely change how scientists view viral infections of algae, also known as phytoplankton—especially the impact of viruses on ecosystem processes like algal bloom formation (and decline) and the cycling of carbon and other chemicals on Earth. It's only when the infectedalgal cells become stressed, such as when they run out of nutrients, that the viruses turn deadly. This entirely new model of infection is widespread in the oceans and stands to fundamentally alter how we view host-virus interactions and the impact of viruses on ecosystems and biogeochemical cycling since it goes against the long-accepted classic model of viruses always being lethal and killing cells.
