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!"

Comment by Dr. Krishna Kumari Challa on July 10, 2020 at 5:43am: The human brain: not just large but finely shaped

Large brains have long differentiated humans and primates from other mammals and there is a clear evidence that brain mass increased through time.

a new study by the University of New England, in collaboration with Italian and American institutes, has shown that the evolution of higher cognitive capacity is not only due to having a larger brain but also due to the brain having the "right" shape.

While brain size has long been the preferred measured trait for anthropological investigations, the brain is not uniform in shape and displays considerable structural variation.

The researchers were particularly interested in how humans evolved to have the distinct large, globular shaped brains we have today.

To answer the question they conducted a novel large-scale evolutionary analysis using a large samples of 3-D digital reconstructions of primate brains.

The team used 3-D shape analysis to measure the morphological variation between the different primate groups and a novel phylogenetic strategy to reconstruct the main morphological changes occurred through the primate lineage.

Their findings reveal that the brains of great apes such as chimpanzees and humans as well as papionin monkeys—baboons and macaques—are characterized by fast evolution and larger brain size. These characteristics sets them apart from smaller lemurs and New World monkeys which evolve more slowly.

The brains of papionins and great apes also have different structures.

"Humans and, to a minor extent, the great apes display a massive reorganization of the brain areas devoted to complex thinking, articulated language, social behaviour and problem solving such as the frontal lobe and the prefrontal cortex.

The teams' heat maps clearly show the great bulging prefrontal cortex of the human brain, whereas the brains of baboons are characterized by changes in the temporal and occipital regions.

Comment by Dr. Krishna Kumari Challa on July 10, 2020 at 5:37am: 5G networks have few health impacts, study finds

Fifth generation or 5G wireless technology, which began being deployed worldwide in 2019, provides faster connectivity and more bandwidth, meaning higher download speeds. But because 5G technology is so new, little is known about the potential health effects from its radiofrequency radiation, which is higher than the current industry standard 4G. The Oregon State study begins to change that.

Based on their study, the researchers don't think 5G radiation is that harmful.

Researchers conducted the research using embryonic zebrafish, a model organism often used to discover interactions between environmental stressors and biological systems. Zebrafish and humans have similar developmental processes and are similar on a genomic level, meaning zebrafish research can easily be applied to humans.

In the study, published July 9 in the journal PLOS ONE, the researchers exposed embryonic zebrafish for two days to 3.5 GHz radiofrequency radiation, the frequency typically used by 5G-enabled cell phones.

They found no significant impacts on mortality, how the embryos formed or the embryos' behavioral response to light. They did find a modest impact on a test that measures the embryos' response to a sudden sound that they will investigate further.

Future research will look at the 5G radiation effects on the same zebrafish used in the study at a gene level and as they develop from embryos to adults, Dasgupta said. The researchers also would like to study the impacts of higher frequencies and higher exposure levels on zebra fish to keep pace with the changing cell phone industry.

The future research will use the same standardized experimental set up used in this study. It involves a box made of copper. The zebra fish embryos are placed on plates, which are put inside the box. The radiation enters the box through an antennae and the copper keeps it inside the box.

Comment by Dr. Krishna Kumari Challa on July 10, 2020 at 5:30am: A 'regime shift' is happening in the Arctic Ocean, scientists say

Scientists at Stanford University have discovered a surprising shift in the Arctic Ocean. Exploding blooms of phytoplankton, the tiny algae at the base of a food web topped by whales and polar bears, have drastically altered the Arctic's ability to transform atmospheric carbon into living matter. Over the past decade, the surge has replaced sea ice loss as the biggest driver of changes in uptake of carbon dioxide by phytoplankton.

the growing influence of phytoplankton biomass may represent a "significant regime shift" for the Arctic, a region that is warming faster than anywhere else on Earth.

The study centers on net primary production (NPP), a measure of how quickly plants and algae convert sunlight and carbon dioxide into sugars that other creatures can eat. "The rates are really important in terms of how much food there is for the rest of the ecosystem. "It's also important because this is one of the main ways that CO² is pulled out of the atmosphere and into the ocean. The increase in NPP over the past decade is due almost exclusively to a recent increase in phytoplankton biomass.

These microscopic algae were once metabolizing more carbon across the Arctic simply because they were gaining more open water over longer growing seasons, thanks to climate-driven changes in ice cover. Now, they are growing more concentrated, like a thickening algae soup.

In a given volume of water, more phytoplankton were able to grow each year.

Comment by Dr. Krishna Kumari Challa on July 10, 2020 at 5:19am: A system for swarm robotics applications inspired by pheromone communication in insects

Nature is one of the most valuable sources of inspiration for researchers developing new robots and computational techniques.

A research team at the University of Manchester recently introduced a new technique for swarm robotics applications inspired by the use of pheromones among insect populations. Pheromones are chemical substances that animals and humans release into their surrounding environment, which can elicit a specific set of behaviors in other animals.

The release of pheromones can prompt mating behaviour, alert other animals of a dangerous situation, delineate a territory, or signal the presence of food. In their paper, published in SAGE's Adaptive Behavior journal, the researchers tried to artificially replicate how social insects, such as ants, use pheromones, with the aim of achieving more effective communication among teams of robots.

The main idea was to develop a bio-inspired communication system based on social animals' pheromone communication systems. Researchers wanted to emulate how ants release pheromones and the behaviors that follow. Past studies tried to create artificial pheromone systems using a variety of techniques, for instance, involving the use of alcohol, RFID tags and light as substitutes for the chemicals naturally released by animals. One of the most promising systems developed so far is COSΦ, a system that uses light to emulate pheromone release in humans and animals.

The team designed a system based on COSΦ, which also employs a model describing how pheromones spread across space and over time. This model draws inspiration from how a liquid or fluid flows in nature.

To have a realistic model of the pheromone system, they had to model all the parameters of real pheromones, such as evaporation and diffusion, and consider the environmental impacts such as effects of wind. The model now proposed is a reliable and realistic model that can imitate pheromone communication among insects.

The researchers evaluated their artificial pheromone system in a series of experiments in which a swarm of small mobile robots moved around and adapted to different environmental factors. Their results were highly promising, as their system enabled effective communication and prompted the desired group behaviors among members of the swarm.

They are currently expanding our system in three directions: (1) developing alternative communication systems for use in real-world scenarios, e.g. using light or sound for transferring small data packets within a swarm, (2) expanding the system with additional layers of pheromones, e.g. different colors and bandwidths, and (3) investigating an evolutionary swarm system where individuals improve their interactions with the pheromone over time

Comment by Dr. Krishna Kumari Challa on July 9, 2020 at 6:56am: How good gut bacteria help reduce the risk for heart disease

Scientists have discovered that one of the good bacteria found in the human gut has a benefit that has remained unrecognized until now: The potential to reduce the risk for heart disease.

The bacteria's activity in the intestines reduces production of a chemical that has been linked to the development of clogged arteries. After it's manufactured in the gut, the chemical enters the bloodstream and travels to the liver, where it is converted into its most harmful form.

Researchers have traced the bacteria's behaviour to a family of proteins that they suspect could explain other ways that good gut organisms can contribute to human health. In essence, these microbes compete with bad bacteria for access to the same nutrients in the gut—and if the good bacteria win, they may prevent health problems that can result from how the body metabolizes food.

Much more work is ahead, but the scientists see potential for this microbe, Eubacterium limosum, to be used for therapeutic purposes in the future. Previous research has already shown the bacterium is "good" because it calms inflammation in the gut.

Over the last decade, it has become apparent that bacteria in the human gut influence our health in many ways. The organism studied now affects health by preventing a problematic compound from becoming a worse one.

The chemical linked to the clogged arteries that characterize atherosclerosis is called trimethylamine, or TMA. It is produced during metabolism when some intestinal microbes—generally the bacteria considered unhelpful to humans—interact with certain nutrients from food. Among those nutrients is L-carnitine, a chemical compound found in meat and fish that is also used as a nutritional supplement to improve recovery after exercise.

The researchers discovered that E. limosum interacts with L-carnitine in a different way in the gut, and that interaction eliminates L-carnitine's role in production of TMA (other nutrients also participate in TMA production in the gut).

The researchers attribute the bacteria's beneficial behaviour to a protein called MtcB, an enzyme that cuts specific molecules off of compounds to help bacteria generate energy and survive. The process is called demethylation, and involves the removal of one methyle group—a carbon atom surrounded by three hydrogen atoms—to change a compound's structure or function.

The bacterium does this for its own benefit, but it has the downstream effect of reducing the toxicity of TMA.
