         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!"

Novel biomarker and modelling could help better identify lethal arrhythmias
Researchers at the School of Biomedical Engineering & Imaging Sciences at Kings College London, in collaboration with colleagues at the Royal Brompton & Hartfield NHS Foundation Trust, have identified a novel imaging-biomarker that can be used to help differentiate risk levels of lethal arrhythmias (irregular heartbeat) in patients with problematic left ventricles. For the first time, they have used detailed computational modelling to also understand why this biomarker is important, in the hopes it will help clinical translation and personalise medicine. Published in JACC: Electro Electrophysiology, the researchers also showed that patient-specific computational simulations alone could be used as a predictive tool to identify individual risk of arrhythmias.

Small brain device proves big game changer for severely paralysed patients

A tiny device the size of a small paperclip has been shown to help patients with upper limb paralysis to text, email and even shop online in the first human trial. The device, Stentrode, has been implanted successfully in two patients, who both suffer from severe paralysis due to motor neuron disease (MND) also known amyotrophic lateral sclerosis (ALS) and neither had complete ability to move their upper limbs. Published in the Journal of NeuroInterventional Surgery, the results found the Stentrode was able to wirelessly restore the transmission of brain impulses out of the body. This enabled the patients to successfully complete daily tasks such as online banking, shopping and texting, which previously had not been available to them.

Skilled surgeons boost colon cancer survival by 70%

Patients of more technically skilled surgeons, as assessed by review of operative video, have better long-term survival after surgery for the treatment of colon cancer, reports a new  Medicine study. Patients whose surgery was performed by a highly skilled surgeon had a 70 percent lower risk of dying over five years compared to patients with a lower skilled surgeon, the study found.

**Studying life at the extremes

Researchers have invented methods to study microbes that thrive in the world’s most inhospitable environments.

Microbes cling to life in some of Earth’s most extreme environments, from toxic hot springs to high-altitude deserts. These ‘extremophiles’ include organisms that can survive near-boiling heat or near-freezing cold, high pressure or high salt, as well as environments steeped in acids, alkalis, metals or radioactivity.

Coercing these organisms to live in laboratories creates many challenges. Nonetheless, papers published on extremophiles have doubled in the past decade. Some scientists are drawn to the novelty of the organisms, searching for ones that are undescribed or that might harbour useful enzymes for industrial processes or antibiotics to save lives. Others simply find that the best organism for their scientific questions happens to have extreme preferences.

It’s a circumstance that has forced researchers who study extremophiles to invent new laboratory methods for handling them. To identify, culture, genetically manipulate and observe extremophiles, researchers often tweak the methods used in more run-of-the-mill organisms. Whereas some techniques can be easily transferred — from one thermophile to other heat-lovers, say — others have to be adapted for each new organism.

Each extremophile is going to have its own set of challenges. How scientists are trying to overcome them? Read here: https://www.nature.com/articles/d41586-020-03055-0?utm_source=Natur...

Put the baking soda back in the bottle: banned sodium bicarbonate ‘milkshakes’ don’t make racehorses faster

The controversial and banned practice of giving horses baking soda “milkshakes” before a race doesn’t work, according to our analysis of the available research.

Racing folklore says sodium bicarbonate milkshakes can boost racehorses’ endurance because the alkalinity of the baking soda helps counter the buildup of lactic acid in the blood when running.

But our systematic research review, recently published in the Journal of Equine Veterinary Science reveals milkshakes don’t boost horses’ athletic performance.

This means any trainer still tempted to flout the ban on this tactic would be endangering their horses’ welfare and risking heavy sanctions over a practice that is basically snake oil.

**Using radar to detect foreign objects in foods

Foreign objects—glass splinters, for example—that find their way into foods can be hazardous to consumers. Established X-ray techniques detect primarily metals—glass, plastic and wood pose a challenge. SAMMI, a new prototype, fills this gap: using radar, it has already detected glass splinters in sandwich cookies, as well as missing pieces of chocolate in advent calendars.

Any number of things can go awry during manufacture and cause glass splinters, metal shavings, wood splinters or plastic pieces to end up in the product. Product recalls not only damage companies financially, they also result in a loss of consumer confidence. Manufacturers therefore have a keen interest in inspecting their products for foreign objects. Currently, they do this primarily with X-ray machines, but these do not reliably detect all foreign objects. While they can easily identify metals, they often have difficulty with plastics, wood and glass. This means that, despite inspections, there is still a certain residual risk for manufacturers.

SAMMI, a prototype developed at the Fraunhofer Institute for High Frequency Physics and Radar Techniques FHR, can now close this gap and provide greater security in  production. "Our system is based on millimeter waves and can augment established X-ray techniques," says Daniel Behrendt, business unit spokesperson at Fraunhofer FHR. "It detects the foreign matter that X-ray techniques can easily overlook—that is, glass splinters, plastics and wood. However, it is not able to penetrate metals, which in return is detected by X-ray techniques." Another advantage of the technology is that the millimeter waves used to inspect the foods pose no health risk.

The inspection works as follows: the food is placed on a  and transported through the machine. Above the conveyor, the transmitting antenna rotates and transmits its waves through the product; below it, the receiving antenna receives these waves. The millimeter waves are uniquely attenuated by each of the different food materials and undergo a specific delay in their transit time. This makes it possible to identify not only the structure and composition of the food, but also the slightest deviations from those—such as are caused by foreign objects, for instance. Assigning a pixel to each measurement point and encoding the changes with different colors produces an image of the investigated object on which the foreign matter is immediately evident. Even packaged goods can be inspected in this way, non-destructively and without physical contact.

New way of cooking rice removes arsenic and retains mineral nutrients, study shows

Cooking rice in a certain way removes over 50 percent of the naturally occurring arsenic in brown rice, and 74 percent in white rice, according to new research. Importantly, this new method does not reduce micronutrients in the rice.

This way of cooking rice ( called the "parboiling with absorption method" (PBA)), removes most of the arsenic, while keeping most nutrients in the cooked rice.

The PBA method involves parboiling the rice in pre-boiled water for five minutes before draining and refreshing the water, then cooking it on a lower heat to absorb all the water.

Manoj Menon et al. Improved rice cooking approach to maximize arsenic removal while preserving nutrient elements, Science of The Total Environment (2020). DOI: 10.1016/j.scitotenv.2020.143341

Scientists identify specific brain region and circuits controlling attention

The attentional control that organisms need to succeed in their goals comes from two abilities: the focus to ignore distractions and the discipline to curb impulses. A new study  neuroscientists shows that these abilities are independent, but that the activity of norepinephrine-producing neurons in a single brain region, the locus coeruleus, controls both by targeting two distinct areas of the prefrontal cortex.

 Andrea Bari el al., "Differential attentional control mechanisms by two distinct noradrenergic coeruleo-frontal cortical pathways," PNAS (2020). www.pnas.org/cgi/doi/10.1073/pnas.2015635117

Bats can predict the future, researchers discover

Bats are quite skilled at predicting one thing: where to find dinner ( in the future). 

Bats calculate where their prey is headed by building on-the-fly predictive models of target motion from echoes researchers find. The models are so robust, bats can continue to track prey even when it temporarily vanishes behind echo-blocking obstacles like trees.

Although predicting object motion paths through vision has been extensively studied, these findings, published today in the journal PNAS, are the first to examine the comparable process in hearing. The work enhances the understanding of auditory-guided behaviours in animals and humans, including sight-impaired people who use listen to sounds to track objects in their surroundings.

Just the way a tennis player needs to find out when and where they will hit the ball, a bat needs to anticipate when and where it will make contact with the insect it's hunting. The insect is flying. The bat is also flying. In this very rapidly changing environment, if the bat were to just rely on the information it got from the most recent echo, it would miss the insect.

The bat uses the time delay between each echolocation call and the resulting echoes to determine how far away prey is. They tilt their heads to catch the changing intensity of echoes to figure out where the prey is in the horizontal plane. Bats must put together echo information about object distance and direction to successfully track an erratic moving insect.

But because bats are such good hunters, the research team thought that in addition, the bats must also be somehow using this information to predict where they prey is headed.

Researchers hypothesized that bats use both the velocity information from the timing of the echoes and further adjust their head aim. When they tested this model with their data, they saw it fit very well.

The question of prediction is important because an animal must plan ahead to decide what it's going to do next. A visual animal or a human has a stream of information coming in, but for bats it's remarkable because they're doing this with only brief acoustic snapshots.

Although bats are studied here, the findings apply to any animals that track moving sounds, and even to people, like the blind, who use clicks and cane taps to help them navigate while avoiding obstacles.

Angeles Salles el al., "Echolocating bats accumulate information from acoustic snapshots to predict auditory object motion," PNAS (2020). www.pnas.org/cgi/doi/10.1073/pnas.2011719117
