         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!"

Boat strikes can be deadly for whale populations all over the world The surge in online shopping that began during the pandemic has led to an increase in cargo ships hauling those goods across the Atlantic to the busy Port of New York and New Jersey. Those ships, larger than they were in the past in order to carry more shipping containers, are also taking new routes in an effort to avoid clogging up shipping lanes like in years past, according to The Times. The Port Authority of New York and New Jersey saw a 27 percent increase in volume last year compared to 2019 levels, and shipping traffic along the East Coast has increased as boats have started making down-and-back trips to retrieve empty shipping containers. While NOAA has proposed speed limits, which could give whales time to move out of the way of oncoming ships, the fact remains that whales are always going to follow their food. "When the whales are in these channels, you have to cross your fingers and hope there are no collisions," Paul Sieswerda, executive director of New York City-based research group Gotham Whale, told The Times. Boat strikes can cause internal injuries from the blunt force trauma, and their propellers can inflict large gashes. Two whales that washed up dead along the Atlantic Coast this month were determined to have been struck by vessels, USA Today reported. This isn't the first time experts have raised the alarm about ships harming whale populations. A year ago, scientists began calling for cargo ships to start rerouting in order to protect endangered blue whales that live off the coast of Sri Lanka. Mediterranean Shipping Company, the largest container line in the world, complied with the request, and animal welfare groups said at the time that if other companies followed, it could reduce ship strikes by 95 percent.

A Rise in Online Shopping Partially to Blame For Recent Spike in Whale Deaths

Our addiction to online shopping is contributing to the recent spike in whale deaths, The New York Times reports.

Since early December, 23 whales have washed up dead along the East Coast, according to data the National Oceanic and Atmospheric Administration provided to The Times. Their deaths are due to a confluence of factors, both environmental and the result of human interference.

NOAA has been tracking an "unusual mortality event" among the Atlantic Coast humpback whale population since 2016, but the recent spike in whale deaths – which has included humpback whales, minke whales, and North Atlantic right whales, which are critically endangered – prompted the NOAA Fisheries to address the crisis during a call with reporters in January.

Lauren Gaches, the agency's public affairs director, said during the call that climate change is partly to blame for the number of whales washing up dead, because warming oceans are causing the fish they eat to move closer to shore.

"We're seeing populations of many marine species adapting by moving into new areas where conditions are more favorable," Gaches said.

"Changing distributions of prey impact larger marine species that depend on them. This can lead to increased interactions with humans as some whales move closer to near-shore habitats."

Which means as some whales seek out prey, they're moving into the path of cargo ships, which have gotten bigger and more plentiful over the past three years.

Understanding the role quantum tunneling plays in the building and rearrangements of molecules could have important ramifications in the calculations of energy release in nuclear reactions, such as those involving hydrogen in stars and fusion reactors here on Earth.

While we've modeled this phenomenon for examples involving reactions between a negatively charged form of deuterium – an isotope of hydrogen containing a neutron – and dihydrogen or H2, proving the numbers experimentally requires a challenging level of precision.

To accomplish this, Wild and his colleagues cooled negative deuterium ions to a temperature that brought them close to a standstill before introducing a gas made of hydrogen molecules.

Without heat, the deuterium ion was far less likely to have the energy required to force hydrogen molecules into a rearrangement of atoms. Yet it also forced the particles into sitting quietly near one another, giving them more time to bond through tunneling.

In their experiment, scientists give possible reactions in the trap about 15 minutes and then determine the amount of hydrogen ions formed. From their number, they can deduce how often a reaction has occurred.

That figure is just over 5 x 10-20 reactions per second taking place in each cubic centimeter, or around one tunneling event for around every hundred billion collisions. So not a lot. Though the experiment does back up previous modeling, confirming a benchmark that can be used in predictions elsewhere.

Given tunneling plays a fairly important role in a diverse range of nuclear and chemical reactions, much of which is also likely to occur out in the cold depths of space, getting a precise grip on the factors at play gives us a more solid grounding to base our predictions on.

For The First Time Ever, Physicists See Molecules Form Through Quantum Tunneling

Chemistry takes effort. Whether it's by raising the temperature, increasing the odds that compatible atoms will collide in a heated smash-up, or increasing the pressure and squeezing them together, building molecules usually demands a certain cost in energy.

Quantum theory does provide a workaround if you're patient. And a team of researchers from the University of Innsbruck in Austria has finally seen the quantum tunneling in action in a world-first experiment measuring the merger of deuterium ions with hydrogen molecules.

Tunneling is a quirk of the quantum universe that makes it seem like particles can pass through obstacles that are ordinarily too hard to overcome.

In chemistry, this obstacle is the energy required for atoms to bond with one another, or with existing molecules.

Yet theory says that, in extremely rare instances, it's possible for atoms in close proximity to 'tunnel' their way through this energy barrier and connect without any effort.

Quantum mechanics allows particles to break through the energetic barrier due to their quantum mechanical wave properties, and a reaction occurs.

Quantum waves are the ghosts that drive the behaviors of objects like electrons, photons, and even entire groups of atoms, blurring their existence before any observation so they sit not in any one precise place but occupy a continuum of possible positions.

This blurring is insignificant for larger objects like molecules, cats, and galaxies. But as we zoom in on individual subatomic particles, the range of possibilities expands, forcing the location states of various quantum waves to overlap.

When that happens, particles have a slight chance of appearing where they have no business being, tunneling into regions that would otherwise require a great deal of force to enter.

One of those regions for an electron might be within the bonding-zone of a chemical reaction, welding together neighboring atoms and molecules without the boom-crash-crush of heat or pressure.

Researchers have discovered a new type of coexistence between algae and fungi

Researchers  have described the symbiotic relationship between fungi and algae.  The coexistence of algae and corticioid basidiomycetes, which are common in temperate forests, has been given a new name: "alcobiosis." Their work has been published in Scientific Reports.

Years ago, during field trips, researchers were repeatedly puzzled to find a layer of green algae where some of the fungal coatings on wood or bark (so-called corticioid fungi) are disturbed. They discovered that this is a close symbiosis of fungi and algae, not a lichen, though, because the fungus does not depend on its alga for nourishment.

The new term introduced by the researchers for this type of coexistence, "alcobiosis," is formed by letters from the three key words: algae, corticioid fungi and symbiosis.

In the course of several years, the team of researchers gathered a large number of samples and performed DNA sequencing of the algal and fungal partners. They discovered that the symbiosis is very common and occurs in a great many corticioid fungi across the class of agaricomycetes. Individual fungal species are usually faithful to a specific algal species from a range of algae described in various alcobioses.

Ensuing physiological measurements of algal activity in alcobioses confirmed that the algae are alive, active and engage heavily in photosynthesis, which proves that they prosper inside fungal tissue. Alcobioses bear a striking resemblance to lichens, but differ from them in that the fungal partner does not depend on its alga for nourishment.

And so the main unknown still is in what way this symbiosis is beneficial for each of the partners.

But this study shows alcobioses as a widespread phenomenon which includes a large number of algae and fungi.

During their research, the authors also discovered that the spread of alcobioses is aided by small gastropods who often feed on corticioid fungi. Their excrements contain viable cells of algae and fungi who give rise to new alcobiotic coating shortly after. This type of reproduction is similar to lichen "isidia" (i.e., specific lichen thallus structures used in vegetative reproduction). Alcobioses are clearly visible to the naked eye and it is easy to distinguish them from similar fungi that do not form this kind of relationship.

Alcobioses are common in urban areas, too. Lyomyces sambuci, pictured here, is abundant on elder bark.

How to stop bird flu becoming a pandemic

After avian influenza killed a girl in Cambodia last week, fears are rising about the virus’s potential to spark a human pandemic. It’s hard to say whether this will actually happen, says veterinary pathologist Thijs Kuiken. Versions of the H5N1 influenza virus have been circulating in birds for about 25 years, but the discovery of a variant that transmits between mink increases the risk that the virus could start spreading in humans. Scientists say it’s important to keep tracking the disease’s spread.... Because drugs and vaccines against H5N1 are already available, a bird flu pandemic would probably be more manageable than COVID-19.

Scientists push the boundaries of manipulating light at the submicroscopic level

A team of researchers  has shown light can be moved within a distance which is smaller than its own wavelength—a level of unprecedented precision.

Scientists have demonstrated that a beam of light can not only be confined to a spot which is 50 times smaller than its own wavelength, but that also—in a first of its kind—the spot can be moved by miniscule amounts at the point where the light is confined. The detailed findings of their theoretical study are published in the journal Optica.

Confining and controlling light on ever smaller volumes is one of the defining challenges in modern photonics; the science behind the generation, detection and manipulation of light. How tightly the light is confined determines the limits for the observability of nanoparticles, as well as the intensity and the precision of light-based devices. One example is optical tweezers. These are widely used in laboratories around the world in fields such as that of DNA research. They consist of highly focused laser beams that trap, manipulate and move particles with astounding precision. One of the limitations with standard optical tweezers is that lenses cannot focus beams on lengths much smaller than the laser beam's own wavelength, limiting the achievable precision.

By its nature, light is indeed very difficult to localize on a smaller length scale than its wavelength, a critical threshold known as the Abbe limit. However, using a sophisticated model and numerical simulation, scientists have successfully demonstrated a novel approach to localize and dynamically manipulate light at a sub-wavelength scale.

Social animals should limit individuality to conform with the behaviour of the group, says study

Scientists  have observed that group safety was improved when animals paid attention to the behaviours of each other.

Their findings, accepted for publication in PLoS Computational Biology, reveal that simple social behavioral rules can drive conformity behaviour in groups, eroding consistent behavioural differences shown by individual animals.

Personality suppression may be a common strategy in group-living animals, and in particular, we should tend to see the behaviors of the most adventurous or shy individuals shifting towards what the majority of the group are doing.

The team modeled the behavior of a small group of animals with differing tendencies while performing risky behaviours when traveling away from a safe home site towards a foraging site. They then compared this to their behaviour while completing the same activity in a group.

The group-aware individuals spent longer in the safe space and moved more quickly to the foraging spot, making the mission less dangerous. Groups are usually made up of individuals who are different to each other in the way that they normally behave—these consistent individual differences are what determines the personality of the individual.

This study was based on fish behaviour. 

When faced with a social task,  researchers found that the fish tend to suppress their own behavior, and instead conform with what other fish in the group are doing.

 If individuals pay attention to other group members, this has an overall impact on the efficiency of the group, and demonstrates that simple social behaviors can result in the suppression of individual personalities.

.This suggests that compromise may lie at the heart of many social behaviors across the animal kingdom.
