         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!"

Bird genes are multitaskers, say scientists

Scientists  have found that although male and female birds have an almost identical set of genes, they function differently in each sex through a mechanism called alternative splicing.

Males and females of the same bird species can be strikingly different. For example, in addition to fundamental differences in reproduction, the sexes can show profound variation in behavior, colouration, metabolism, disease incidence and life history. The team wanted to understand how these remarkable differences develop despite males and females sharing mostly the same DNA.

One notable example of differences between male and  is in the peafowl, peacocks have magnificent plumage, whereas the female peahen is relatively dull. The peacock's  and  evolved to help them attract mates, but having such eye-catching looks can come with negatives such as making them more noticeable to predators.

Features like this are beneficial to the males but may not be beneficial for females, so birds must find a way to evolve different characteristics. So researchers predicted that the secret to these differences must lie in understanding how the same genes are expressed and function differently in males and females.

The team studied the genomes of multiple bird species to understand how they expressed these different qualities in males and females.

Genes encode proteins, large complex molecules which drive processes in the body and are responsible for the function and structure of the body's tissues. Before genes can be used to make proteins, their DNA sequence is transcribed into RNA, an intermediary molecule that contains the instructions for making proteins.

The scientists found that males and females differ in how bits of RNA are stitched together, meaning that the same gene can produce a large number of distinct proteins and functions depending on which sex the gene is expressed in. This process is called alternative splicing. It is likely that this genetic process is really important for generating biodiversity, not only in birds but across the whole animal kingdom. The study  revealed hundreds of bird genes that use this method to enable the evolution of sex differences. The researchers showed that these genes have evolved remarkably rapidly as a result of the different selection pressures experienced by males and females.

New measurements show moon has hazardous radiation levels

Future moon explorers will be bombarded with two to three times more radiation than astronauts aboard the International Space Station, a health hazard that will require thick-walled shelters for protection, scientists reported  recently.

China's lander on the far side of the moon is providing the first full measurements of radiation exposure from the lunar surface, vital information for NASA and others aiming to send astronauts to the moon, the study noted.

Astronauts would get 200 to 1,000 times more radiation on the moon than what we experience on Earth—or five to 10 times more than passengers on a trans-Atlantic airline flight.

The difference is, however, that we're not on such a flight for as long as astronauts would be when they're exploring the moon. Cancer is the primary risk.

Humans are not really made for these radiation levels and should protect themselves when on the moon. Radiation levels should be pretty much the same all over the moon, except for near the walls of deep craters.

 Secure nano-carrier delivers medications directly to cells

Medications often have unwanted side-effects. One reason is that they reach not only the unhealthy cells for which they are intended, but also reach and have an impact on healthy cells. Researchers  have now developed a stable nano-carrier for medications. A special mechanism makes sure the drugs are only released in diseased cells.

The male Y chromosome does more than we thought

New light is being shed on a little-known role of Y chromosome genes, specific to males, that could explain why men suffer differently than women from various diseases, including COVID-19. This  discovery provides a better understanding of how male genes on the Y chromosome allow male cells to function differently from female cells. These results could help to shed some light on why some diseases occur differently in men and women.

Humans each have 23 pairs of chromosomes, including one pair of sex chromosomes. While females carry two X sex chromosomes, males carry one X and one Y chromosome. This male chromosome carries genes that females lack. Although these male genes are expressed in all cells of the body, their only confirmed role to date has been essentially limited to the functions of the sex organs.

In his study, scientists performed a genetic manipulation that inactivated two male genes on the Y chromosome, altering several signalling pathways that play important roles in certain functions of non-sex organ cells. For example, under stress, some of the affected mechanisms could influence the way in which cells in human hearts defend themselves against aggressions such as ischemia (reduced blood supply) or mechanical stress.

In addition, the study showed that these male genes performed their regulatory functions in a way that was unusual compared to the mechanisms generally used by most other genes on the non-sex chromosomes. Thus, instead of specifically activating certain genes by direct action at the genome level, the Y chromosome seems to affect cellular functions by acting on protein production.

The discovery of these differences in function may explain in part why the functions of male Y chromosome genes have so far been poorly understood.

Males differ from females in the manifestation, severity and consequences of most diseases. A recent example of this duality is COVID-19, which has a mortality rate twice as high in men than in women.

Materials scientists learn how to make liquid crystal shape-shift

A new 3-D-printing method will make it easier to manufacture and control the shape of soft robots, artificial muscles and wearable devices.  Researchers show that by controlling the printing temperature of liquid crystal elastomer, or LCE, they can control the material's degree of stiffness and ability to contract—also known as degree of actuation. What's more, they are able to change the stiffness of different areas in the same material by exposing it to heat.

As a proof of concept, the researchers 3-D-printed in a single print, with a single ink, structures whose stiffness and actuation varies by orders of magnitude, from zero to 30 percent. For example, one area of the LCE structure can contract like muscles; and another can be flexible, like tendons. The breakthrough was possible because the team studied LCE closely to better understand its material properties.

Machine learning takes on synthetic biology: algorithms can bioengineer cells for you

Conventional methods of bioengineering are slow and laborious, with trial and error being the main approach.

So now scientists have developed a new tool that adapts machine learning algorithms to the needs of synthetic biology to guide development systematically. The innovation means scientists will not have to spend years developing a meticulous understanding of each part of a cell and what it does in order to manipulate it; instead, with a limited set of training data, the algorithms are able to predict how changes in a cell's DNA or biochemistry will affect its behaviour, then make recommendations for the next engineering cycle along with probabilistic predictions for attaining the desired goal. According to the developers of this technology, if you're able to create new cells to specification in a couple weeks or months instead of years, you could really revolutionize what you can do with bioengineering.

Using deep learning to control the unconsciousness level of patients in an anesthetic state

Researchers have been developing machine learning algorithms for an increasingly wide range of purposes. This includes algorithms that can be applied in healthcare settings, for instance helping clinicians to diagnose specific diseases or neuropsychiatric disorders or monitor the health of patients over time.

They have recently carried out a study investigating the possibility of using deep reinforcement learning to control the levels of unconsciousness of patients who require anesthesia for a medical procedure. They  made significant progress in understanding how anesthetic medications affect neural activity  and now  a multidisciplinary team is studying how to accurately determine anesthetic doses from neural recordings. They also we trained a neural network using the cross-entropy method, by repeatedly letting it run on simulated patients and encouraging actions that led to good outcomes.  developed a deep neural network and trained it to control anesthetic dosing using reinforcement learning within a simulated environment.

How to embrace your scientific artistry

Illustrations can help to get your research the attention it so richly deserves. Three scientific artists offer their advice about how to get started with the right tools, find inspiration and creat.... “One common issue at my zoological illustration and painting workshops is that scientists feel that they are not artistic enough — and artists feel that they are not scientific enough,” says illustrator Justine Hirten. “I encourage my students to accept themselves as legitimate members of both the creative and the scientific communities.”
