         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!"

Ant queens cannibalize their sick offspring and 'recycle' them, new study reveals

Instead of nurturing their sick young, ant queens eat their infected offspring at the first sign of illness then "recycle" them into energy to produce new eggs, a new study led by the University of Oxford has shown. The findings have been published in Current Biology.

Eek!  Nature and Universe don’t care what happens to which mass of atoms!

Ant queens typically found new colonies on their own, and at the early stages are highly vulnerable to their brood being wiped out by disease. Researchers at Oxford's Department of Biology theorized that killing off sick larvae before they become infectious could be a strategy used by queens to combat this threat.

To test this, the researchers presented founding queens of the black garden ant (Lasius niger) with larvae that had been infected with a fungal pathogen Metarhizium for 24 hours. At this point, the infection was lethal, but not yet transmissible. The queens cannibalized 92% of the infected larvae—leaving no remains—but only 6% of control larvae which had not been infected.

Once the queens find a sick larva in the brood pile they get to work immediately and spend several hours chewing them up until they're all consumed.

Despite the potential risk of infection, all queens survived after eating the infected larvae. The researchers suggest the queens may protect themselves by swallowing an acidic, antimicrobial venom which they produce from a special gland at the end of their abdomen. Indeed, some of the queens were seen massaging the opening of this gland during and after cannibalism.

The queens who cannibalized their infected larvae went on to lay 55% more eggs than non-cannibalizing control queens, indicating that the nutrients from the ingested offspring were recycled for reproduction.

Who's to blame when climate change turns the lights off?

Deadly Storms have flooded recently large areas of central Europe and the UK, destroying homes and displacing thousands of people.

With the flooding of sub-stations, the scouring of the foundations of pylons and river embankment failures, the rainstorm has also caused power outages many miles away. This will create yet more disruption as sewage pumping stations stall, train and tram services halt and vehicle charging points fail.

The UK saw this ripple of infrastructure failure in the 2007 summer floods.

India too saw this ripple effect  in this monsoon season.

 All systems fail occasionally. But infrastructure is increasingly vulnerable to disruptions caused by extreme weather, which is being made more severe and frequent as a result of climate change.

Your home may not be in the path of the next storm but the infrastructure it relies on might be.

Tap water is also a greener option. Plastic bottles make up the second most common ocean pollutant, accounting for 12% of all plastic waste. Globally, just 9% of these bottles are recycled, meaning that most end up in landfill or incinerators, or are 'exported' to low and middle income countries, to deal with, begging the question of social justice, they say.

Apart from the waste generated, the process of extracting the raw materials and manufacturing plastic bottles significantly contributes to greenhouse gas emissions, they add.

While some efforts have been made to facilitate the use of drinking water in restaurants and public spaces, and to curb the prevalence of single-use plastics, much more needs to be done, argue the authors.
The reliance on [bottled water] incurs significant health, financial and environmental costs, calling for an urgent re-evaluation of its widespread use.

Bottled water has a huge and growing toll on human and planetary health, experts warn

The huge and growing toll bottled water is taking on human and planetary health warrants an urgent rethink of its use as 1 million bottles are bought every minute around the globe, with that figure set to rise further still amid escalating demand, warn population health experts in a commentary published in the open access journal BMJ Global Health.

Some 2 billion people around the world with limited or no access to safe drinking water rely on bottled water. But for the rest of us, it's largely a matter of convenience and the unshaken belief—aided and abetted by industry marketing—that bottled water is safer and often healthier than tap water.

It isn't, insist the experts!

That's because bottled water often isn't subject to the same rigorous quality and safety standards as tap water, and it can carry the risk of harmful chemicals leaching from the plastic bottles used for it, especially if it's stored for a long time, and/or exposed to sunlight and high temperatures, they explain (the same is true for cold drinks).

Between an estimated 10% and 78% of bottled water samples contain contaminants, including microplastics, often classified as hormone (endocrine) disruptors, and various other substances including phthalates (used to make plastics more durable) and bisphenol A (BPA).

Microplastic contamination is associated with oxidative stress, immune system dysregulation, and changes in blood fat levels. And BPA exposure has been linked to later-life health issues, such as high blood pressure, cardiovascular disease, diabetes and obesity, they add.

Extinct volcanoes a 'rich' source of rare earth elements, research suggests

A mysterious type of iron-rich magma entombed within extinct volcanoes is likely abundant with rare earth elements and could offer a new way to source these in-demand metals, according to new research.

Rare earth elements are found in smartphones, flat screen TVs, magnets, and even trains and missiles. They are also vital to the development of electric vehicles and renewable energy technologies such as wind turbines.

The iron-rich magma that solidified to form some extinct volcanoes is up to a hundred times more efficient at concentrating rare earth metals than the magmas that commonly erupt from active volcanoes.

The findings suggest that these iron-rich extinct volcanoes across the globe, such as El Laco in Chile, could be studied for the presence of rare earth elements." The researchers simulated volcanic eruptions in the lab by sourcing rocks similar to those from iron-rich extinct volcanoes. They put these rocks into a pressurized furnace and heated them to extremely high temperatures to melt them and learn more about the minerals inside the rocks.

This is how they discovered the abundance of rare earth elements contained in iron-rich volcanic rocks.

The scientists created a model for testing smart lighting that aims to keep plants' ability to photosynthesize steady over the course of a day, while still lowering electricity costs. They found that an optimization algorithm could cut electricity costs by 12% without compromising plants' carbon fixation, just by varying the intensity of the light.

They then tested whether varying light intensity affected the growth of leafy plants like spinach which are often grown in vertical farms, and found that there was no negative effect. This remained true even when the plants were subject to irregularly changing light intensity, rather than a predictable, regular pattern.

Indoor vertical farming could future-proof food demand

To make sure everyone eats well in our crowded world, we need to innovate. Vertical farming systems, which grow plants intensively in an indoor setting, could be part of the answer—but to use them on a large scale we need to overcome key problems, especially the management of the energy-intensive, expensive light the plants need to grow.

Now scientists show how manipulating light according to the needs of specific crops could make them grow stronger and healthier while minimizing energy use.

The biggest benefit of vertical farming systems is that healthy food  can be grown much more closely to consumers in places where this is impossible otherwise: in mega-cities, in deserts, and in places that are cold and dark during large parts of the year. But the biggest challenge is the costs associated with electricity use.

  Many vertical farming systems are run using constant environmental conditions, which require lots of expensive electricity for maintenance. The scientists' analysis shows that these demanding conditions are unnecessary: using dynamic environmental control, they suggest, we can achieve vertical farming which is more cost-effective and which raises healthier plants.

Scientists were motivated by the rhythms that plants show on diurnal as well as on developmental timescales, which require their growing environment to be adjusted regularly in order to steer their growth perfectly.

They outlined a strategy that makes use of plant physiology knowledge, novel sensing and modeling techniques, and novel varieties specifically bred for vertical farming systems.

Because plants' biological functions are heavily influenced by environmental conditions like temperature changes, light wavelengths, and the amount of CO2 in the atmosphere, manipulating the environment allows a vertical farming system to manipulate plant development.

Lighting is a critical variable; all plants need it to photosynthesize, and different light wavelengths have different effects on different plants. This variable is also particularly sensitive to electricity pricing, so offers opportunities to make efficiency gains.

COVID origin at Wuhan market, says study
The hunt for the origins of COVID-19 has circled back to an animal market in Wuhan, China that was linked to many of the earliest cases of the disease. Researchers reanalysed genomes collected from the market shortly after it was shut down on 1 January 2020. They identified several animal species that could have passed SARS-CoV-2, the coronavirus that causes COVID-19, to people. The study establishes the presence of animals and the virus at the market, although it does not confirm whether the animals themselves were infected with the virus. The researchers argue that their reanalysis adds weight to the market being the site of the first spillover events, in which animals infected humans.

Acidic water damages corals, shellfish and the phytoplankton that feeds a host of marine species.

This means it also disrupts food supplies for billions of people, as well as limiting the oceans' capacity to absorb more CO2 and thus help limit global warming.

The only one of the nine planetary boundaries that is not close to being crossed concerns the state of the planet's protective ozone layer.

Man-made chemicals have damaged this shield, causing acid rain, but it has started recovering since a number of these chemicals were banned in 1987.

A ninth threshold—concerning concentrations of minute particles in the atmosphere that can cause heart and lung diseases -– is close to the danger limit.

But the researchers said the risk showed signs of receding slightly due to efforts by several countries to improve air quality, such as banning the most pollutant petrol and diesel cars.
They warned, however, that concentrations of fine particles could still soar in countries that are rapidly industrializing.

The PIK set these nine planetary danger levels to warn humans against tipping Earth's natural systems past points of no return.

"These tipping points... if crossed, would lead to irreversible and catastrophic outcomes for billions of people and many future generations on Earth", experts say.
All nine planetary boundaries are "interconnected" so breaching one crucial limit can destabilize Earth's entire life system.

World's oceans near critical acidification level: Report

The world's oceans are close to becoming too acidic to properly sustain marine life or help stabilize the climate, a new report said this week.

The report by the Potsdam Institute for Climate Impact Research (PIK) details nine factors that are crucial for regulating the planet's ability to sustain life.

In six of these areas, the safe limit has already been exceeded in recent years as a result of human activity.

The crucial threshold for ocean acidification could soon become the seventh to be breached, according to the PIK's first Planetary Health Check.

The safe boundaries that have already been crossed concern crucial—and related—factors including climate change; the loss of natural species, natural habitat and freshwater; and a rise in pollutants, including plastics and chemical fertilizers used in agriculture.

The sustainable level of ocean acidification is now also set to be exceeded, largely as a result of ever-increasing emissions of carbon dioxide (CO2) created by burning fossil fuels like oil, coal and gas.

As CO2 emissions increase, more of it dissolves in sea water... making the oceans more acidic.

Even with rapid emission cuts, some level of continued acidification may be unavoidable due to the CO2 already emitted and the time it takes for the ocean system to respond.

Therefore, breaching the ocean acidification boundary appears inevitable within the coming years.
