         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!"

Study finds that high levels of a growth factor increases risk for several cancers

A study of almost 400,000  participants has identified a new link between raised levels of the growth factor IGF-1 and increased thyroid cancer risk and has confirmed associations with breast, prostate and colorectal cancer. This could lead to new preventative strategies, including diet and lifestyle interventions.

IGF-1 (insulin-like growth factor-1) helps to support normal cell growth and development, processes which can lead to cancer if they become dysregulated.

Electrons that flow like water in ultra-pure graphene

Since its discovery in 2004, graphene has largely been known for its quantum properties. But recently, researchers discovered that electron flow in graphene at certain temperatures could be described using the very classical laws of hydrodynamics.

People observed that electrons in graphene flowed collectively, akin to water in a pipe. This was exciting not only because it provided a new playground to study electron interactions but also because it could also provide a new way to control electrons.”

Since that initial discovery, researchers wondered if the behavior could be replicated in other quantum materials.

Now, a team of researchers have classified different types of hydrodynamic behaviours which could arise in quantum materials where electrons flow collectively. This research opens the door to studying exotic physics and electron hydrodynamics in a range of new materials beyond graphene and paves the way for potentially interesting applications for extremely energy efficient electronics.

First Compelling Evidence of Organisms That Eat Viruses as a Food Source

Two types of single-celled organisms found drifting in the waters of the Gulf of Maine off North America's coast just might be the first true virophages known to science.

Researchers identified the virus grazers after sifting nearly 1,700 plankton cells collected from the waters of the gulf and the Mediterranean Sea, and amplifying the DNA inside each and every one to create individualised genomic libraries.

In the gulf sample, half of the libraries contained snippets of genes from 50 or more different viruses. In the Mediterranean sample it was closer to a third of the sample.

Most of the virus sequences appeared to be from bacteriophages – pathogens that invade and replicate inside bacterial cells.

Bacteria are a common food source for marine protozoans, so finding their dinner came pre-infected isn't much of a surprise.

But representatives belonging to groups known as choanozoans and picozoans, both collected from the waters off North America, stood out as a little unusual.

For one thing, in many cases there was not a shred of bacterial DNA in sight. Without any signs of a bacterial brunch, it's hard to know how bacteriophage genes might have ended up inside the planktons' cells.

More compelling still is that the two completely different phyla of protozoans shared near-identical viral sequences, making it hard to argue that infection was responsible.

While the evidence for a diet of virus snacks could be considered circumstantial, it's not unlike finding dark crumbs dusting your toddler's fingers near an empty box of Oreos. Nobody's going to blame you for being suspicious.

Scientists Have Found The Molecule That Allows Bacteria to 'Exhale' Electricity

For mouthless, lungless bacteria, breathing is a bit more complicated than it is for humans. We inhale oxygen and exhale carbon dioxide; Geobacter - a ubiquitous, groundwater-dwelling genus of bacteria - swallow up organic waste and 'exhale' electrons, generating a tiny electric current in the process.

Researchers show conscious processes in birds' brains for the first time

By measuring brain signals, a neuroscience research group has demonstrated for the first time that corvid songbirds possess subjective experiences. Simultaneously recording behavior and brain activity enabled the group  to show that crows are capable of consciously perceiving sensory input. Until now this type of consciousness has only been witnessed in humans and other primates, which have completely different brain structures to birds.

For humans and our nearest relatives in the animal kingdom, the nonhuman primates, our ability to perceive things consciously is localized in the cerebral cortex. Over many years research has discussed whether animals with brains that are structured completely differently, without a cerebral cortex, are also endowed with conscious perception. Until now however there has been no experimental neurological data to support such a claim.

In order to track conscious processes in birds, the Tübingen scientists trained two crows: they had to signal whether they had seen a stimulus on a screen by moving their heads. Most of the stimuli were perceptually unambiguous: different trials presented either bright figures or no stimulus at all, and the crows reliably signaled the presence or absence of these stimuli, respectively. However, some stimuli were so faint that they were at the threshold of perception: for the same faint stimulus, the crows sometimes indicated that they had seen it, whereas in other cases they reported that there was no stimulus. Here, the subjective perception of the crows came into play.

While the crows responded to the visual stimuli, the researchers simultaneously recorded the activity of individual nerve cells in the brain. When the crows reported having seen something, the nerve cells were active in the period between presentation of the stimulus and the behavioral response. If they did not perceive a stimulus, the nerve cells remained silent. Surprisingly, it was possible to predict the subjective experience of the crows with regard to the stimulus based on the activity of the nerve cells.

These results conclusively show that nerve cells at higher processing levels of the crow's brain are influenced by subjective experience, or more precisely, produce subjective experiences."

This means that in terms of evolutionary history the origins of consciousness could be far older and more widespread in the animal kingdom than previously thought. the capability of conscious experience can be realized in differently structured brains and independently of the cerebral cortex.

Metformin treatment linked to slowed cognitive decline

Metformin is the first-line treatment for most cases of type 2 diabetes and one of the most commonly prescribed medications worldwide, with millions of individuals using it to optimize their blood glucose levels.

A new research study, conducted over six years 

 has revealed an additional effect: individuals with type 2 diabetes who used metformin experienced slower cognitive decline with lower dementia rates than those who did not use the medication.

The findings provide new hope for a means of reducing the risk of dementia in individuals with type 2 diabetes, and potentially those without diabetes who number nearly 47 million people worldwide.

Ecologists confirm Alan Turing's theory for fairy circles

Fairy circles are one of nature's greatest enigmas and most visually stunning phenomena. An international research team has now, for the first time, collected detailed data to show that Alan Turing's model explains the striking vegetation patterns of the Australian fairy circles. In addition, the researchers showed that the grasses that make up these patterns act as "eco-engineers" to modify their own hostile and arid environment, thus keeping the ecosystem functioning.

Researchers used drone technology, spatial statistics, quadrat-based field mapping, and continuous data-recording from a field-weather station. With the drone and a multispectral camera, the researchers mapped the "vitality status" of the Triodia grasses (how strong and how well they grew) in five one-hectare plots and classified them into high- and low-vitality.

The systematic and detailed fieldwork enabled, for the first time in such an ecosystem, a comprehensive test of the 'Turing pattern' theory. Turing's concept was that in certain systems, due to random disturbances and a 'reaction-diffusion' mechanism, interaction between just two diffusible substances was enough to allow strongly patterned structures to spontaneously emerge. Physicists have used this model to explain the striking skin patterns in zebrafish or leopards for instance.

The data show that the unique gap pattern of the Australian fairy circles, which occur only in a small area east of the town of Newman, emerges from ecohydrological biomass-water feedbacks from the grasses. In fact, the fairy circles—with their large diameters of 4m, clay crusts from weathering and resultant water run-off—are a critical extra source of water for the dryland vegetation. Clumps of grasses increased shading and water infiltration around the nearby roots. With increasing years after fire, they merged more and more at the periphery of the vegetation gaps to form a barrier so that they could maximize their water uptake from the fairy circle's runoff. The protective plant cover of grasses could reduce soil-surface temperatures by about 25°C at the hottest time of the day, which facilitates the germination and growth of new grasses. In summary, the scientists found evidence both at the scale of the landscape and at much smaller scales that the grasses, with their cooperative growth dynamics, redistribute the water resources, modulate the physical environment, and thus function as "ecosystem engineers" to modify their own environment and better cope with the arid conditions.

Antifungal preventive drugs reduce mortality risk following lung transplantation: Study

The retrospective study, published in the Annals of the American Thoracic Society, is the largest ever to evaluate the effectiveness of antifungal preventive drugs in lung transplant recipients who are particularly susceptible to invasive fungal infections. These infections are associated with a nearly threefold increase in mortality for lung transplant recipients.

The study showed that  the risk of death within the first year posttransplant is about twice as high in patients not receiving antifungal preventive treatment, compared with those receiving treatment.

White supremacists believe in genetic ‘purity’. Science shows no such thing exists

Science does not support the idea of pure races with ancient origins. In the past few years, genetic sequencing of ancient and modern humans and related species has given us a flood of new information about how human populations have evolved.

The evidence reveals a history of ongoing genetic mingling, due to interbreeding between different populations and even species. Humans from different groups had children together, and even with Neanderthals and members of other now-extinct hominin species.

This mingling occurred constantly in the long process of human migration across the globe. Europeans inhabit one region of a large genetic continuum and are no more or less “pure” than any other population.
