         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 characterize 28 bacteria that produce bioactive substances, offering pharmaceutical potential

Researchers  have characterized 28 actinomycetes and investigated their biotechnological potential.

The results of the study show that all actinomycetes have an inhibiting effect against a panel of test bacteria and yeasts. The researchers have now published their findings in the journal Current Research in Microbial Sciences.

Actinomycetes are bacteria that are known to produce bioactive substances. Two thirds of the antibiotics in use today were originally isolated from these bacteria. The actinomycetes now being investigated were deposited in the DSMZ collection decades ago, but have not yet been characterized in detail.

In their study, the researchers investigated the natural compound synthesis potential of 28 actinomycetes and were able to prove that they have an inhibiting effect against selected other microorganisms. These include clinically relevant antibiotic-resistant bacteria that are on the World Health Organization's Bacterial Priority Pathogens List. The DSMZ's actinomycetes collection contains more than 6,000 strains, some of which have not yet been further analyzed.

Biologists identify traits correlating with all bird extinctions since 1500

Looking to inform the conservation of critically endangered bird species, biologists have completed an analysis identifying traits that correlate with all 216 bird extinctions since 1500.

Species most likely to go extinct sooner were endemic to islands, lacked the ability to fly, had larger bodies and sharply angled wings, and occupied ecologically specific niches, according to research published this month. The work appears in the journal Avian Research.

While some of these findings mirror previous research on extinct birds, they are the first to correlate bird traits with the timing of extinctions.

The team simultaneously analyzed a broad range of biogeographical, ecological and life history traits previously associated with extinction and extinction risk for bird species that have gone extinct as well as those that lack recent confirmed sightings and have therefore disappeared.

While only around 2% of the world's bird species have gone extinct since 1500, the year Kittelberger's analysis begins, even more had already disappeared by then. Before 1500, however, there is not as reliable a record of the birds that went extinct and data on their traits and characteristics.

This timing coincides with the rise of scientific observation, resulting in systematic documentation of plant and animal life.

Today, 1,314 bird species are at risk of extinction, according to the IUCN Red List of Threatened Species, or about 12% of the total.

Importantly, they examine biological correlates of bird extinctions through the lens of when birds went extinct, providing a novel extinction timing element that helps better inform why birds with certain traits disappeared when they did.

By identifying traits that most predispose birds to extinction, the findings can help guide conservation efforts of hundreds of species that are at peril.

Brains grew faster as humans evolved

Modern humans, Neanderthals, and other recent relatives on our human family tree evolved bigger brains much more rapidly than earlier species, a new study of human brain evolution has found.

Scientists found that brain size increased gradually within each ancient human species rather than through sudden leaps between species. The research, published November 26 in the Proceedings of the National Academy of Sciences, overturns long-standing ideas about human brain evolution.

The team assembled the largest-ever dataset of ancient human fossils spanning 7 million years and used advanced computational and statistical methods to account for gaps in the fossil record. These innovative approaches provided the most comprehensive view yet of how brain size evolved over time.

This study completely changes our understanding of how human brains evolved. It was previously thought that brain size jumps dramatically between species, like new upgrades between the latest computer models. This study instead shows a steady, incremental 'software update' happening within each species over millions of years.

The research challenges old ideas that some species, like Neanderthals, were unchanging and unable to adapt and instead highlights gradual and continuous change as the driving force behind brain size evolution.

Big evolutionary changes don't always need dramatic events. They can happen through small, gradual improvements over time, much like how we learn and adapt today, say the researchers.

The researchers also uncovered a striking pattern: While larger-bodied species generally had bigger brains, the variation observed within an individual species did not consistently correlate with body size. Brain size evolution across long evolutionary timescales extending millions of years is therefore shaped by different factors to those observed within individual species—highlighting the complexity of evolutionary pressures on brain size.

The conclusion:  Our hallmark large brains arose primarily from gradual changes within individual species.

The sound of traffic increases stress and anxiety, research shows

Manmade sounds such as vehicle traffic can mask the positive impact of nature soundscapes on people's stress and anxiety, according to a study published November 27, 2024, in the open-access journal PLOS ONE 

Existing research shows that natural sounds, like birdsong, can lower blood pressure, heart, and respiratory rates, as well as self-reported stress and anxiety. Conversely, anthropogenic soundscapes, like traffic or aircraft noise, are hypothesized to have negative effects on human health and well-being in a variety of ways.

The study found that listening to a natural soundscape reduced self-reported stress and anxiety levels, and also enhanced mood recovery after a stressor. However, the benefits of improved mood associated with the natural soundscape was limited when traffic sounds were included.

The natural soundscape alone was associated with the lowest levels of stress and anxiety, with the highest levels reported after the soundscape that included 40 miles per hour traffic.

The authors conclude that reducing traffic speed in urban areas might influence human health and well-being not only through its safety impacts, but also through its effect on natural soundscapes.

The study shows that listening to natural soundscapes can reduce stress and anxiety, and that anthropogenic sounds such as traffic noise can mask potential positive impacts. Reducing traffic speeds in cities is therefore an important step towards more people experiencing the positive effects of nature on their health and well-being.

The researchers proposed a mathematical definition of cell death. It's based on the way cellular states, including metabolism, can be controlled by modulating the activities of enzymes. They define dead states as those states from which cells cannot return to an apparent "living" state, regardless of the modulation of any biochemical processes.
This led them to develop a computational method for quantifying the life-death boundary, which they call "stoichiometric rays." The method was developed by focusing on enzymatic reactions and the second law of thermodynamics, which states that systems naturally move from ordered to disordered states.

Researchers could use these methods to better understand, control, and possibly even reverse, cellular death in controlled lab experiments.
The conclusion : We naively believe that death is irreversible, but it is not so trivial and does not have to be the case. Should death come more under our control, human beings, our understanding of life, and society will change completely. In this sense, to understand death is crucial in terms of science and also in terms of social implications. This is one step towards that goal.

A mathematical definition of cell death?

Cellular death is a fundamental concept in the biological sciences. Given its significance, its definition depends on the context in which it takes place, and lacks a general mathematical definition.

Researchers now propose a new mathematical definition of death based on whether a potentially dead cell can return to a predefined "representative state of living," which are the states of being that we can confidently call "alive." The researchers' work could be useful for biological researchers and future medical research.

The paper is published in Physical Review Research.

While it's not something we like to think about, death comes for us all eventually, whether you're an animal, a plant, or even a cell. And even though we can all differentiate between what is alive and dead, it might be surprising to know that death at a cellular level lacks a widely recognized mathematical definition.

Given that cell death plays such an important role in various biological processes and can have important health implications, it's of critical importance to understand what we really mean by cellular death, especially in research.

The scientific goal is to understand the inherent difference between life and nonlife, mathematically; why the transition from nonlife to life is so difficult, while the other way around is so easy. 

The  aim in this project was to develop a mathematical definition and computational method to quantify the life-death boundary. Researchers were able to do this by exploiting an important feature of biological reaction systems, specifically enzymatic reactions within cells.

Long COVID brain fog linked to lung function

In patients with long COVID, lower pulmonary gas exchange may be associated with impaired cognitive function, according to a study presented at the annual meeting of the Radiological Society of North America (RSNA).

People with long COVID may exhibit a wide variety of symptoms, including difficulty concentrating ("brain fog"), change in sense of smell or taste, fatigue, joint or muscle pain, dyspnea (shortness of breath), digestive symptoms, and more. These symptoms may persist for weeks, months, or even years after COVID-19 infection.

In pulmonary gas exchange, oxygen moves from the lungs to the bloodstream, while carbon dioxide moves from the bloodstream to the lungs.

If these findings can be generalized to the long COVID population, the study suggests that there may be a causative relationship between cognitive dysfunction and lung dysfunction, suggesting a potential treatment strategy using methods that target improved gas exchange, say the researchers.

This work also tells us how important it is to move away from a 'one-size-fits-all' approach to managing type 2 diabetes, and we hope that this will allow us to find ways to offer more precise treatments that treat the condition more effectively and reduces the development of diabetes complications.

Genes & Health will contribute to future efforts to ensure that precision medicine approaches are developed and bring real benefits to south Asian communities living with, and at risk of, type 2 diabetes.

Why are South Asians more diabetic prone?

A genetic predisposition to having lower insulin production and less healthy fat distribution are major causes of early-onset type 2 diabetes in  South Asian people, according to new research. These genetic factors also lead to quicker development of health complications, earlier need for insulin treatment, and a weaker response to some medications.

The findings, published in Nature Medicine, reinforce the need to understand how genetic variation across different population groups can influence the onset of diseases, treatment responses, and disease progression.

Key discoveries from the study include:

  • Genetic signatures in South Asians: The younger age of onset in South Asians is strongly linked to genetic signatures that lead to both lower insulin production and unfavorable patterns of body fat distribution and obesity. The most significant genetic signature influencing whether a South Asian person develops type 2 diabetes, and at a young age, is a reduced ability of pancreatic beta cells to produce insulin. This genetic signature also increases the risk of gestational diabetes and the progression of gestational diabetes to type 2 diabetes after pregnancy.

    • Treatment responses: The genetic signatures identified in the study provide vital clues about how different people may respond to type 2 diabetes treatments. For example, individuals with high genetic risk for low insulin production were less likely to respond to common medications such as sodium-glucose co-transporter 2 inhibitors and were more likely to require insulin therapy.

    • High genetic-risk group identified: The study identified a subset of people with extreme genetic signatures for both low  production and unfavorable fat distribution. These individuals were found to develop type 2 diabetes an average of eight years earlier and at lower body mass index. Over time, these individuals were more likely to need  and were at higher risk for diabetes complications such as eye and kidney disease.
