         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".

"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!

Asynchronous Reality — where everything remains real except the flow of time

Comment by Dr. Krishna Kumari Challa 2 hours ago

Scientists discover norovirus and other 'stomach viruses' can spread through saliva

A class of viruses known to cause severe diarrheal diseases—including the one famous for widespread outbreaks on cruise ships—can grow in the salivary glands of mice and spread through their saliva, scientists have discovered. The findings show that a new route of transmission exists for these common viruses, which afflict billions of people each year worldwide and can be deadly.

The transmission of these so-called enteric viruses through saliva suggests that coughing, talking, sneezing, sharing food and utensils, and even kissing all have the potential for spreading the viruses. The new findings still need to be confirmed in human studies.

The findings, which appear in the journal Nature, could lead to better ways to prevent, diagnose, and treat diseases caused by these viruses, potentially saving lives.

Researchers have known for some time that enteric viruses, such as noroviruses and rotaviruses, can spread by eating food or drinking liquids contaminated with fecal matter containing these viruses. Enteric viruses were thought to bypass the salivary gland and target the intestines, exiting later through feces. Although some scientists have suspected there may be another route of transmission, this theory remained largely untested until now.

Now researchers will need to confirm that salivary transmission of enteric viruses is possible in humans. If they find that it is, the researchers said, they may also discover that this route of transmission is even more common than the conventional route. A finding such as that could help explain, they said, why the high number of enteric virus infections each year worldwide fails to adequately account for fecal contamination as the sole transmission route.

Turning methane into methanol under ambient conditions using light

An international team of researchers has developed a fast and economical method of converting methane, or natural gas, into liquid methanol at ambient temperature and pressure. The method takes place under continuous flow over a photo-catalytic material using visible light to drive the conversion.

To help observe how the process works and how selective it is, the researchers used neutron scattering at the VISION instrument at Oak Ridge National Laboratory's Spallation Neutron Source.

The method involves a continuous flow of methane/oxygen-saturated water over a novel metal-organic framework (MOF) catalyst. The MOF is porous and contains different components that each have a role in absorbing light, transferring electrons and activating and bringing together methane and oxygen. The liquid methanol is easily extracted from the water. Such a process has commonly been considered "a holy grail of catalysis" and is an area of focus for research supported by the U.S. Department of Energy. Details of the team's findings, titled "Direct photo-oxidation of methane to methanol over a mono-iron hydroxyl site," are published in Nature Materials.

Tearless onions

How are they created and do they actually work?

Slicing through an onion damages cells, causing enzymes and other substances that are normally kept apart to spill out and react together. In standard onions the result is a sulphur-containing chemical called syn-propanethial-S-oxide, which resembles tear gas. This forms an irritating acid when it comes into contact with water in your eyes.

Some research groups have created onions that are genetically modified to lack an enzyme that leads to syn-propanethial-S-oxide, but these have not yet made it to market.

The tearless onions – Sunions – now in shops were created by repeatedly cross-breeding milder varieties containing lower levels of pyruvate. This substance is a by-product of the same reaction that forms syn-propanethial-S-oxide and also has a good measure of pungency.

First known case of COVID from a cat

Scientists in Thailand have established that a cat passed SARS-CoV-2 to a veterinary surgeon. Given the scale of the pandemic and the close contact between cats and people, some researchers are not surprised. But establishing the direction of viral spread — from cat to person or from person to cat — is tricky. In this case, a cat belonging to a COVID-19-positive family sneezed in the face o.... Such cases of cat-to-human transmission are probably rare, and researchers emphasize that people should care for their cats — and perhaps take extra precautions when handling cats that might be infected — and not abandon them.

Life in the Earth's interior is as productive as in some ocean waters

Terrestrial and marine habitats have been considered the ecosystems with the highest primary production on Earth by far. Microscopic algae in the upper layers of the oceans and plants on land bind atmospheric carbon (CO2) and produce plant material driven by photosynthesis. Since sunlight does not penetrate into the subsurface, hardly any such primary production is to be expected.

However, genetic analyses of microorganisms in  have indicated that even here many microorganisms are capable of primary production. In the absence of light, they must obtain the energy from oxidizing , like from reduced sulfur of the surrounding rocks. However, the role of primary producers in the subsurface had never been confirmed before.

Groundwater is one of our most important sources of clean drinking water. The groundwater environment of the carbonate aquifers alone, which is the focus of the study, provides about ten percent of the world's drinking water. With this in mind, the researchers carried out measurements of microbial microorganism carbon fixation in a subsurface aquifer, 5 to 90 meters belowground.

Based on the measured carbon fixation rates, the researchers conservatively extrapolated global primary production in carbonate groundwater to be 110 million metric tons of carbon per year. Collectively, the net primary productivity of approximately 66 percent of the planet's groundwater reservoirs would total 260 million metric tons of carbon per year, which is approximately 0.5 percent that of marine systems and 0.25 percent of global net primary production estimates.

Since there is very little energy available in these nutrient-poor and permanently dark habitats, even a small percentage of the global primary production is a surprise.

The researchers also sought to identify the microorganisms responsible for fixing carbon and generating new biomass within the aquifer. Metagenomic analyses point to a highly abundant microorganism not closely related to previously studied bacteria, within an uncharacterized order of Nitrospiria. As food, these organisms are thought to form the basis of life for the entire groundwater ecosystem with all of its thousands of microbial species, similar to the role algae play in the oceans or plants on land.

Bacteria's shapeshifting behaviour clue to new treatments for urinary tract infections

Urinary tract infections are both very common and potentially very dangerous. Thousands of women  suffer from a UTI in their lifetime, and most of these women will have an infection requiring treatment with antibiotics. 

Around 80 percent of UTIs are caused by uropathogenic E. coli (UPEC), which is increasingly resistant to antibiotics. E. coli-related death due to antimicrobial resistance is the leading cause of bacterial fatalities worldwide.

In a bid to aid discovery of new treatment options, researchers are using state-of-the-art microscopy to pinpoint how these bacteria spread and multiply.

The latest research examined the shapeshifting behavior of UPEC. During a UTI infection cycle, the bacteria form spaghetti-like filaments hundreds of times their normal lengths before reverting to their original form.

The study, which is published in Nature Communications, used a human bladder cell infection model to generate the filaments, and look at their reversal back to rod shape.

While we don't fully understand why they do this extreme lifestyle make-over, we know they must revert to their original size before they can reinfect new bladder cells.

Researchers  used advanced microscopy to follow two key cell division proteins and their localisation dynamics during reversal. We found that the normal rules for regulation of cell division in bacteria does not fully apply in filaments.

By giving the first clues into how the reversal of filamentation is regulated during infection, scientists may be laying the foundation for identifying new ways to combat UTIs.

 The long filaments formed by the bacteria appeared to break open the infected human cells, through a previously unknown mechanism called infection-related filamentation (IRF).

The devastating eruption of these bacteria from the cells of the bladder that they invade probably contributes to the extensive damage and pain experienced during a UTI.

If scientists identify why and how the bacteria shifts their shapes this enables alternative treatments or preventions.

The analyses carried out now yielded many interesting findings. Most notably, the results showed that the functional connectivity between large-scale brain networks can predict age with good accuracy and that it varies across the lifespan. More specifically, they found that the connectivity between ECN and DMN brain regions accounts for a significant portion of age variability.

Interestingly, the researchers found that when they also included the SN (a set of brain regions that selects salient external or internal stimuli for the brain to focus its attention on) in their analyses, they could predict a person's age with even greater accuracy. In the future, their work could help to better understand the brain connectivity  patterns associated with the decline in cognitive abilities observed in older age.

Functional connections between different brain networks can predict a person's age

Neuroscientists have been trying to understand for decades how the human brain changes over the lifespan. This could ultimately help to devise more effective treatments for neurological and cognitive disorders primarily observed in the elderly.

Researchers  have recently carried out a study investigating the relationship between age and the functional coupling between specific neural networks in the brain. Their paper, published in Psychology and Aging, shows that the connectivity between certain brain regions can predict people's chronological age with a high level of accuracy.

The differences in cognitive functioning among people of different ages are well documented. The idea that these differences are associated with changes in brain connectivity (i.e., the way in which brain regions and networks communicate with each other) was introduced and discussed in many neuroscience papers.

The present one deals with the Q:Can we use patterns of brain connectivity when people are not doing any tasks to predict their age?

Scientists analyzed data collected from a large cohort of 547 participants between 18 and 88 years old, part of a publicly available brain imaging dataset compiled by the Cambridge Centre for Aging and Neuroscience (CamCAN). By analyzing these data, they  firstly investigated whether connectivity between the executive control network (ECN) and default mode network (DMN) regions in the brain can predict age.

To do this, they used a well-established statistical technique called multiple regression analysis. They further examined how connectivity between ECN, DMN, and another region, the salience network (SN)—which is thought to mitigate how ECN and DMN regions talk to each other—impacts the strength of the connections between ECN and DMN areas.

Oceans saved us, now we can return the favour

Humanity must heal oceans made sick by climate change, pollution and overfishing in order to rescue marine life and save ourselves, experts warned ahead of a major UN conference.

By absorbing—decade after decade—a quarter of CO2 pollution and more than 90 percent of excess heat from global warming, oceans have kept Earth's terrestrial surface liveable.

Our species has returned the favor by dumping mountains of plastic waste into the sea, emptying the deep blue of big fish, and poisoning coastlines with toxic chemicals and agricultural runoff that create dead zones bereft of oxygen.

"If we don't do the right things now, we might end up with a dead oceans”
