         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!"

Forensic science: laser technique distinguishes human and animal blood

New research published recently could soon offer law enforcement another valuable crime scene tool—a quick and accurate way to distinguish human blood from animal blood.

In a proof-of-concept study researchers used laser technology to rapidly differentiate human blood samples from nearly a dozen animal species.

This could prove to be key in car crash investigations when the suspect is unsure if a human or animal was struck.

technique relies on Raman , which works by shining a laser on a dry blood sample and measuring the interaction. No two samples produce the same results, offering a unique measurement (similar to a fingerprint). The results are instantaneous and do not destroy the sample, preserving it for future testing.

In the new study researchers used attenuated total reflection Fourier transform-infrared (ATR FT-IR) spectroscopy, a complementary technique to Raman spectroscopy, on 15 human blood samples and a total of 89 cat, dog, rabbit, horse, cow, pig, opossum and raccoon blood samples. Although each sample  appeared nearly identical to the naked eye, the ATR FT-IR spectroscopy analysis, coupled with advanced statistics, was able to classify them as human or animal with 100 percent accuracy.

Samples from three other species—deer, elk and ferret—were included to further test the statistical model, and were all correctly classified.

SARS-CoV-2-like particles very sensitive to temperature

Why do corona viruses become more active in winter?

A new study tested how temperatures and humidity affect the structure of individual SARS-Cov-2  on surfaces. They found that just moderate temperature increases broke down the virus' structure, while humidity had very little impact. In order to remain infectious, the SARS-Cov-2 membrane needs a specific web of proteins arranged in a particular order. When that structure falls apart, it becomes less infectious. The findings suggest that as temperatures begin to drop, particles on surfaces will remain infectious longer.

This is the first study to analyze the mechanics of the virus on an individual particle level, but the findings agree with large-scale observations of other coronaviruses that appear to infect more people during the winter months.

Temperature makes a huge difference, and that's what the researchers saw. To the point where the packaging of the virus was completely destroyed by even moderate temperature increases. They 

hey tested the virus-like particles on glass surfaces under both dry and humid conditions. Using atomic force microscopy they observed how, if at all, the structures changed. The scientists exposed samples to various temperatures under two conditions: with the particles inside a liquid buffer solution, and with the particles dried out in the open. In both liquid and bare conditions, elevating the temperature to about 93 degrees F for 30 minutes degraded the outer structure. The effect was stronger on the dry particles than on the liquid-protected ones. In contrast, surfaces at about 71 degrees F caused little to no damage, suggesting that particles in room  conditions or outside in cooler weather will remain infectious longer.

They saw very little difference under levels of humidity on surfaces, however the scientists stress that humidity likely does matter when the  are in the air by affecting how fast the aerosols dry out. The research team is continuing to study the molecular details of virus-like particle degradation.

A. Sharma et al, Structural stability of SARS-CoV-2 virus like particles degrades with temperature, Biochemical and Biophysical Research Communications (2020). DOI: 10.1016/j.bbrc.2020.11.080

Exploring the role of prefrontal-amygdala brain circuits in social decision-making

In recent years, neuroscientists have been trying to understand the neural underpinnings of social behaviors and cognition. Studies on animal species, including primates and rodents, have identified a number of brain regions and neural circuits that may underpin social behaviors.

Researchers a have been conducting extensive research investigating the roles of the medial prefrontal cortex and the amygdala in social decision-making, particularly focusing on the interactions between different brain regions in the prefrontal-amygdala pathways. In a recent paper published in Nature Neuroscience, the researchers reviewed and summarized the evidence gathered in past studies that examined the neural mechanisms of social decision-making in humans, non-human primates and rodents.

Overall, the findings reviewed  the researchers highlight the crucial role of interactions between the medial prefrontal cortex and amygdala in the social cognition of a wide variety of animal species. The  has previously been found to contribute to a number of sensorimotor, cognitive and emotional processes, while the amygdala is a region deep within the brain that integrates a number of emotions, emotional reactions and motivations.

Some recent studies also revealed that neural ensembles involved in the processing of information that is both related and unrelated to social communication can interact with one another. These interactions appear to facilitate or attenuate social functions, increasing or decreasing their prevalence over non-social functions.

Magnetic fluids are used in many different areas, including medicine, electronics, mechanical engineering, ecology, etc. Such a wide range of applications is explained by a number of its useful properties. Researchers from Peter the Great St.Petersburg Polytechnic University (SPbPU) in collaboration with colleagues from Jiangsu Normal University (JSNU) discovered new effects in magnetic fluids, which will increase its effectiveness for medical purposes in future. The results were published in Springer Proceedings in Physics.

These ‘beetlebots’ keep flying, even after crashing into poles

Comment by Dr. Krishna Kumari Challa on December 18, 2020 at 12:08pm

Why are our tears salty?

Well, all fluids in our bodies have a little bit of salt in them. This salt is made into electricity to help our muscles contract and our brains to think. The amount of salt in our body fluids (like tears, sweat, and saliva) is about the same as the amount of salt in our blood — just under 1%, or about two teaspoons of salt per litre.

The saltiness of your tears can actually vary depending on what kind of tears your eyes are making.

That’s right, your eyes — or a part of your eyes called the lacrimal gland, to be precise — make three different types of tears. These are called basal tears, reflex tears and emotional tears.

  • basal tears keep your eyes wet and stop nasty germs infecting your eyes
  • reflex tears are made when your eyes need to wash away something harmful that gets in, such as smoke or a grain of sand
  • emotional tears are the kind you cry when you’re feeling very happy or sad.

Basal tears and reflex tears have more salt in them than emotional tears, which is important for keeping your eyes healthy. Emotional tears contain more of other things, including a hormone (a special type of chemical in your body) that works like a natural painkiller. This might help to explain why we sometimes feel better after having a good cry.

Scientist tests new technology for removing, destroying 'forever ch...

University of Rhode Island hydrogeologist Thomas Boving and colleagues at EnChem Engineering Inc. are testing a proprietary new technology for quickly removing and destroying hazardous chemical compounds from soil and groundwater. If proven effective, the technology could soon be applied to cleaning up the abundant per- and polyfluoroalkyl substances, collectively referred to as PFAS and 'forever chemicals,' that contaminate drinking water supplies.

PFAS compounds have been in use for more than 60 years and are found in common household goods like non-stick cookware, stain-proof carpets and pizza boxes, as well as in firefighting foams and other industrial products. Because they do not break down easily in the environment, they find their way into human and animal tissues and can lead to many serious diseases.

First, they flushed the compounds out of the ground by pumping in a sugar molecule that has the ability to remove PFAS from the soil and groundwater. Then they pumped the solution out of the ground and hit it with a chemical oxidation process to destroy the compounds.

The most consumed species of mussels contain microplastics all arou...

"If you eat mussels, you eat microplastics." 

A research team investigated the microplastic load of four mussel species which are particularly often sold as food in supermarkets from twelve countries around the world. The scientists now present their research results in the journal Environmental Pollution.

All the samples analyzed contained microplastic particles, and the researchers detected a total of nine different types of plastic. Polypropylene (PP) and polyethylene terephthalate (PET) were the most common types of plastic. Both are plastics ubiquitous to people's everyday lives all over the world. To make the analyses of different sized mussels comparable, one gram of mussel meat was used as a fixed reference. According to the study, one gram of mussel meat contained between 0.13 and 2.45 microplastic particles. Mussel samples from the North Atlantic and South Pacific were the most contaminated. Because mussels filter out microplastic particles from the water in addition to food particles, a microplastic investigation of the mussels allows indirect conclusions to be drawn about pollution in their respective areas of origin.

The  detected in the  were of a size of between three and 5,000 micrometers, i.e. between 0.003 and five millimeters.
