         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!"

Researchers recover 75,000 'deleted' files from pre-owned USB drives

Highly sensitive tax returns, contracts and bank statements were among 75,000 "deleted" files recovered by cybersecurity researchers as part of an  investigation into the risks of selling used USB drives over the internet.

The team made the startling discovery after purchasing just 100 devices on a popular online auction site and examining them further.

98 of the USBs seemed, at face value, to be empty. However, with publicly available tools it is worryingly easy to retrieve data.

Only 32 of the drives had been properly wiped. Partial files were extracted from 26 devices and every single file was extracted from the remaining 42 USB drives.

Many of the files extracted were determined to be of  high sensivity, and included files named "passwords", contracts, bank statements and tax returns. Other USB drives contained images with embedded location data.

so the researchers say, the way many computers delete files doesn't actually remove them. What happens is that the file is removed from the index so that they are effectively hidden from view. They're still there though and if you know how, you can easily recover them using publicly available forensics tools. Software is freely available that can permanently wipe USB drives, so if you are going to sell a device we would strongly recommend using that. If you're planning to discard a USB device without selling it, you should destroy it with a hammer—make it impossible for a third party to get hold of the data it stores. If you're planning to buy a new USB drive, the best way of mitigating the risks is to buy an encrypted device.

Study finds environmentally-friendly' tableware harms marine animals

A new  study compares the effects of two types of disposable dishes on the marine environment—regular plastic disposable dishes and more expensive bioplastic disposable dishes certified by various international organizations—and determines that the bioplastic dishes had a similar effect on marine animals as regular plastic dishes. Moreover, the study finds that bioplastic does not degrade rapidly in the marine environment.

People buy expensive disposable dishes and utensils with the special bioplastic standard seal of compliance on the assumption that they are being environmentally responsible. This study proves that while this may be good for their conscience, it can still damage the environment.

Bioplastics are made of natural, renewable materials, and biodegrade relatively fast under certain conditions. Disposable dishes and utensils made of bioplastics were granted various international standard seals and are marketed to consumers as environmentally friendly. However, they don't meet these expectations. 

In the short term, both types of plastic have a similar detrimental effect, according tot eh study. Bioplastics are made of natural materials and, in that sense, they are more beneficial environmentally speaking. But they may also contain toxins just like regular plastic dishes and they do not biodegrade quickly in the aquatic habitat.

Using quantum properties of light to transmit information

Researchers have taken an important step toward developing a communications network that exchanges information across long distances by using photons, mass-less measures of light that are key elements of quantum computing and quantum communications systems.

The research team has designed a nanoscale node made out of magnetic and semiconducting materials that could interact with other nodes, using laser light to emit and accept photons.

The development of such a quantum network—designed to take advantage of the physical properties of light and matter characterized by quantum mechanics—promises faster, more efficient ways to communicate, compute, and detect objects and materials as compared to networks currently used for computing and communications.

Early big-game hunters of the Americas were female, researchers suggest

For centuries, historians and scientists mostly agreed that when early human groups sought food, men hunted and women gathered. However, a 9,000-year-old female hunter burial in the Andes Mountains of South America reveals a different story, according to new research conducted.

An archaeological discovery and analysis of early burial practices overturns the long-held 'man-the-hunter' hypothesis.

These findings are particularly timely in light of contemporary conversations surrounding gendered labour practices and inequality. Labour practices among recent hunter-gatherer societies are highly gendered, which might lead some to believe that sexist inequalities in things like pay or rank are somehow 'natural.' But it's now clear that sexual division of labour was fundamentally different—likely more equitable—in our species' deep hunter-gatherer past.

During archaeological excavations at a high-altitude site called Wilamaya Patjxa in what is now Peru, researchers found an early burial that contained a hunting toolkit with projectile points and animal-processing tools. The objects accompanying people in death tend to be those that accompanied them in life, researchers said. It was determined that the hunter was likely female based on findings by the team's osteologist, James Watson of The University of Arizona. Watson's sex estimate was later confirmed by dental protein analysis.

 The surprising discovery of an early female hunter burial led the team to ask whether she was part of a broader pattern of female hunters or merely a one-off. Looking at published records of late Pleistocene and early Holocene burials throughout North and South America, the researchers identified 429 individuals from 107 sites. Of those, 27 individuals were associated with big-game hunting tools—11 were female and 15 were male. The sample was sufficient to "warrant the conclusion that female participation in early big-game hunting was likely nontrivial," researchers said. Moreover, the analysis identified the Wilamaya Patjxa female hunter as the earliest hunter burial in the Americas.

Statistical analysis shows that somewhere between 30 to 50 percent of hunters in these populations were female, the study said. This level of participation stands in stark contrast to recent hunter-gatherers, and even farming and capitalist societies, where hunting is a decidedly male activity with low levels of female participation, certainly under 30 percent

Radical diagnostic could save millions of people at risk of dying from blood loss

In a world-first outcome that could save more than two million lives globally each year, researchers have developed a diagnostic using a glass slide, Teflon film and a piece of paper that can test for levels of fibrinogen concentration in blood in less than four minutes. Fibrinogen is a protein found in blood that is needed for clotting. When a patient experiences traumatic injury, such as a serious car accident, or major surgery and childbirth complications, fibrinogen is required in their blood to prevent major haemorrhaging and death from blood loss. Typically, heavily bleeding patients must be transported to a hospital or emergency centre where they undergo diagnostic tests before being treated. These tests are time consuming and costly as they require expensive equipment, specialised/trained personnel and can take up to half an hour.

When a patient is bleeding heavily and has received several blood transfusions, their levels of fibrinogen drop. Even after dozens of transfusions, patients keep bleeding. What they need is an injection of fibrinogen. However, if patients receive too much fibrinogen, they can also die.

This new diagnostic can eliminate the preparation time, labour and transportation difficulties of traditional techniques used in the hospital. It can diagnose hypofibrinogenemia in critically bleeding patients anywhere in the world, and can drastically reduce the time to treatment needed for fibrinogen replacement therapy. The test can take less than four minutes, about five times faster than the current gold standard methods.

Hot or cold, weather alone has no significant effect on COVID-19 spread

The link between weather and COVID-19 is complicated. Weather influences the environment in which the coronavirus must survive before infecting a new host. But it also influences human behaviour, which moves the virus from one host to another.

Aa new study finding that temperature and humidity do not play a significant role in coronavirus spread.

That means whether it's hot or cold outside, the transmission of COVID-19 from one person to the next depends almost entirely on human behaviour.

The effect of weather is low and other features such as mobility have more impact than weather. In terms of relative importance, weather is one of the last parameters.

Across scales, the scientists found that the weather had nearly no influence. When it was compared with other factors using a statistical metric that breaks down the relative contribution of each factor toward a particular outcome, the weather's relative importance at the county scale was less than 3%, with no indication that a specific type of weather promoted spread over another.

In contrast, the data showed the clear influence of human behavior—and the outsized influence of individual behaviors. Taking trips and spending time away from home were the top two contributing factors to COVID-19 growth, with a relative importance of about 34% and 26% respectively. The next two important factors were population and urban density, with a relative importance of about 23% and 13% respectively.

COVID-19 'super-spreading' events play outsized role in overall disease transmission

There have been many documented cases of COVID-19 "super-spreading" events, in which one person infected with the SARS-CoV-2 virus infects many other people. But how much of a role do these events play in the overall spread of the disease? A new study  suggests that they have a much larger impact than expected.

The study of about 60 super-spreading events shows that events where one person infects more than six other people are much more common than would be expected if the range of transmission rates followed statistical distributions commonly used in epidemiology.

Based on their findings, the researchers also developed a mathematical model of COVID-19 transmission, which they used to show that limiting gatherings to 10 or fewer people could significantly reduce the number of super-spreading events and lower the overall number of infections.

Super-spreading events are likely more important than most of us had initially realized. Even though they are extreme events, they are probable and thus are likely occurring at a higher frequency than we thought. If we can control the super-spreading events, we have a much greater chance of getting this pandemic under control, according to this study.
