         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!"

Using plasma technology to feed the world

Using state-of-the-art plasma technology to make cheap fertilizer for small farmers may sound like magic, but it has now become reality. Researchers have built a small plasma-powered plant that produces nitrogen-based liquid fertilizer only using sun, water and air. The plant is easy to set up, sustainable and very efficient.

Physics of tumours: Cancer cells become fluidised and squeeze through tissue

Researchers  have achieved a breakthrough in research into how cancer cells spread. They demonstrated for the first time how cells deform in order to move in dense tumor tissues and squeeze past neighboring cells. The researchers found that motile cells work together to fluidise tumour tissue.

These first observations of a phase transition in human tumours change our basic concepts of tumour progression and could improve cancer diagnosis and therapy.

 the research showed that human tumours contain solid and fluid cell clusters, which would be a breakthrough in scientists' understanding of tumour mechanics.

Scientists identify over 140,000 virus species in the human gut

Viruses are the most numerous biological entities on the planet. Now researchers  have identified over 140,000 viral species living in the human gut, more than half of which have never been seen before.

The paper, published today (18 February 2021) in Cell, contains an analysis of over 28,000 gut microbiome samples collected in different parts of the world. The number and diversity of the viruses the researchers found was surprisingly high, and the data opens up new research avenues for understanding how viruses living in the gut affect .

The human gut is an incredibly biodiverse environment. In addition to bacteria, hundreds of thousands of viruses called bacteriophages, which can infect bacteria, also live there.

It is known that imbalances in our gut microbiome can contribute to diseases and complex conditions such as Inflammatory Bowel Disease, allergies and obesity. But relatively little is known about the role our gut bacteria, and the bacteriophages that infect them, play in human health and disease.

Using a DNA-sequencing method called metagenomics, researchers at the Wellcome Sanger Institute and EMBL's European Bioinformatics Institute (EMBL-EBI) explored and catalogued the biodiversity of the viral species found in 28,060 public human gut metagenomes and 2,898 bacterial isolate genomes cultured from the human gut.

The analysis identified over 140,000 viral species living in the human gut, more than half of which have never been seen before.

Metabolic mutations help bacteria resist drug treatment

Bacteria have many ways to evade the antibiotics that we use against them.

Most of the mutations known to confer resistance occur in the genes targeted by a particular antibiotic. Other resistance mutations allow bacteria to break down antibiotics or pump them out through their cell membranes.

Researchers have now identified another class of mutations that helps bacteria develop resistance. In a study of E. coli, they discovered that mutations to genes involved in metabolism can also help bacteria to evade the toxic effects of several different antibiotics. The findings shed light on a fundamental facet of how antibiotics work, and suggest potential new avenues for developing drugs that could enhance the effectiveness of existing antibiotics.

This study gives us insights into how we can boost the effectiveness of existing antibiotics because it emphasizes that downstream metabolism plays an important role. Specifically, the work indicates that the killing efficacy of an antibiotic can be enhanced if one can elevate the metabolic response of the treated pathogen. By turning down their metabolism after drug treatment, bacteria can prevent the buildup of harmful byproducts.

The findings raise the possibility that forcing bacteria into a heightened metabolic state could increase the effectiveness of existing antibiotics, the researchers say.

Scientists entered people’s dreams and got them ‘talking’

Because Lucid dreamers can hear and answer questions while still asleep, scientists find. 

Scientists have successfully "talked" to a sleeping person in real-time by invading their dreams, a new study shows. The researchers say it's like trying to communicate with an astronaut on another world.

Dreamers can follow instructions, solve simple math problems and answer yes-no questions without ever waking up, according to the results of four experiments described Thursday (Feb. 18) in the journal Current Biology.  

The researchers communicated directly with sleeping participants by asking them questions and having them respond with eye or facial movements during lucid dreams — when people are at minimum aware that they are dreaming. (Some lucid dreamers can control what happens in their dreams.) 

Studying dreams is difficult because people often forget or distort details after waking up. That's in part because the brain doesn't form many new memories while sleeping and has a limited capacity to accurately store information after the dream has ended, according to the study

To overcome this limitation, the researchers attempted to communicate with people while they were still dreaming. Because the study participants were having lucid dreams, that meant they could make a conscious effort to respond to cues coming in from the outside world, the researchers hypothesized. 

Researchers placed electrodes on the participants' heads, to measure their brainwaves; next to their eyes, to track eye movements; and on their chin, to measure muscle activity. They used this data to determine when the participants entered the rapid eye movement (REM) stage of sleep, when lucid dreams are most likely to occur.

The researchers used several techniques across the experiments to communicate with dreamers during REM sleep, including asking them spoken questions and giving them encoded messages in flashing lights, beeping tones and physical taps, that the dreamers had been trained to decipher. If dreamers received and understood the question or message during a lucid dream, they then responded with a set of distinctive eye or facial movements that were interpreted by the electrodes.

"Such two-way communication — from outside to inside the dream and back out again — is something that may seem to belong to the domain of science fiction.

COVID vaccines and safety: what the research says

It is clear that coronavirus vaccines are safe and effective, but as more are rolled out, researchers are learning about the extent and nature of side effects.
  • The two messenger-RNA (mRNA) vaccines, made by Moderna and Pfizer–BioNTech, seem to cause similar reactions. A significant portion of people experience non-serious reactions, such a sore arm or a headache. That proportion is larger than the one for the annual flu shot — perhaps because the mRNA COVID-19 vaccines generate a particularly strong immune response.
  • A tiny number of people have experienced severe allergic reactions to the vaccines. These are extremely rare and no one has died. Fewer than five people per million doses administered of the Moderna or Pfizer–BioNTech experienced anaphylactic reactions. That is based on self-reported data from health-care workers and vaccinated individuals. For the Oxford–AstraZeneca vaccine, 30 cases of anaphylaxis have been confirmed so far, out of a little more than 3 million administered doses.
  • Some researchers have had their eye on polyethylene glycol (PEG) as the anaphylaxis-causing agent in the mRNA vaccines. More research is needed.
  • No deaths have been directly attributed to a COVID-19 jab. But it’s very hard to definitively link a death that happens days or weeks after the vaccine — especially among recipients who are very old or have serious health conditions.
  • Safety data for some other widely used shots, such as the Chinese CoronaVac vaccine or the Russian Sputnik V vaccine, are harder to come by.
