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 June 30, 2021 at 9:46am: Researchers discover unique 'spider web' mechanism that traps, kills viruses

Immunologists have discovered a previously unknown mechanism which acts like a spider web, trapping and killing pathogens such as influenza or SARS-CoV-2, the virus responsible for COVID-19.

The researchers have found that neutrophils, the most abundant white blood cells in the human body, explode when they bind to such pathogens coated in antibodies and release DNA outside of the cell, creating a sticky tangle which acts as a trap.

The findings, published online in the Proceedings of the National Academy of Science, are significant because little is understood about how antibodies neutralize viruses in the respiratory tract.

The discovery has implications for vaccine design and delivery, including aerosol and nasal spray technologies that could help the body head off infections before they have a chance to take hold.

Researchers caution that while the body's spider-web mechanism has the potential to be hugely beneficial, it can cause harm too, including inflammation and further illness when the web formation is uncontrollable.

Comment by Dr. Krishna Kumari Challa on June 29, 2021 at 1:54pm: Broken Heart Syndrome Linked to the Brain

A chronically stressed amygdala can prime the heart to overreact to acute stress events, a new study shows.

Takotsubo syndrome, also known as broken heart syndrome, is a rare, reversible condition with symptoms mimicking a mild heart attack. A disease that disproportionately affects women, TTS is triggered by stressful events such as bankruptcy, the death of a loved one, or divorce, and results in a weakening of the heart’s left ventricle such that it becomes temporarily misshapen.

Previous work has shown that TTS patients have elevated activity in their amygdala, a brain region involved in stress response. What has never been clear, however, is whether this activity in the brain happens as a result of the syndrome or whether it began many years before.

Higher amygdala activity was associated with an increased risk for TTS, and among those with the condition, patients with higher ratios had developed TTS roughly two years earlier following the imaging than those with lower ratios. “We can now show that this syndrome happens as a result of chronic stress over years that makes you vulnerable to developing the syndrome more easily and sooner than [less stressed] people.

This study confirms our suspicion that there’s a relationship between amygdala activity and future risk of Takotsubo.

Comment by Dr. Krishna Kumari Challa on June 29, 2021 at 12:22pm: Study explores how the perception of internal bodily signals influences the concept of self

In contrast with other animal species on Earth, over the course of their life, humans can develop a fairly clear idea of who they are as individuals and what sets them apart from others. This abstract concept of self is known to be fragmented and fuzzy in individuals with certain psychiatric disorders, including schizophrenia, borderline personality disorder and dissociative identity disorder.

Researchers recently authored a review paper examining experimental evidence suggesting that the birth, maintenance and loss of this abstract concept of self is deeply tied to what is known as interoception. This refers to an individual's sense of his/her internal physiological signals.

A couple of years ago, researchers discovered a new bodily illusion. This 'embreathment' illusion, as they called it, suggests that your concept of yourself (i.e., who you think you are) is partly shaped by feelings that come from your viscera, particularly from the heart and the lungs.

They realized that the concept of self has several dimensions, ranging from mundane and material to social and spiritual. They thus decided to investigate the illusion more in depth and try to better understand what it suggested about people's concept of self.

Comment by Dr. Krishna Kumari Challa on June 29, 2021 at 6:14am: Study identifies heart block cause in athletes
An international team of scientists has identified why some endurance athletes experience a heart rhythm disturbance called ‘heart block’.

The study found that long-term exercise in retired racehorses – the best available model of the athlete’s heart - and in mice, triggered molecular changes in a part of the heart known as the atrioventricular (or AV) node.

The work is the latest in a series of studies conducted by the team, showing that endurance exercise directly impacts the electrical wiring system of the heart.

Despite well-recognised cardiovascular benefits, sustained endurance exercise in athletes, footballers and other sportspeople can lead to the development of abnormal heart rhythms - known as cardiac arrhythmias, including heart block.

While benign for many people, heart block - also known as AV block - can be a precursor to more serious heart problems.
The heart’s AV node is part of its electrical conduction system controlled by the autonomic nervous system and electrically connects the atria and ventricles.

It’s well known that athletes are predisposed to heart block which in itself is often benign. But clinical research suggests that this may be ‘a canary in a coalmine’: it can flag up the risk of abnormal heart rhythms which may for example necessitate the implantation of a pacemaker in some individuals.For the first time this research highlights the fundamental adaptations taking place.

The study, published in the leading journal Circulation Research, found that long-term training in both horses and mice caused a reduction in key proteins, known as ion channels, that control AV node conduction.
Training-induced heart block and underlying ion channel changes were reversible when the exercise was stopped or when mice were given a compound known as an anti-microRNA.
It must be stressed that exercise is good for you – and its benefits far outweigh the risks.
Understanding the physiology of the athlete’s heart is incredibly helpful: it could help us develop new interventions for heart block as well as help doctors more effectively monitor heart rhythm disturbances in top-flight professional athletes

Comment by Dr. Krishna Kumari Challa on June 28, 2021 at 11:02am: Muscle's smallest building blocks disappear after stroke

After suffering a stroke, patients often are unable to use the arm on their affected side. Sometimes, they end up holding it close to their body, with the elbow flexed.

In a new study, Northwestern University and Shirley Ryan AbilityLab researchers have discovered that, in an attempt to adapt to this impairment, muscles actually lose sarcomeres—their smallest, most basic building blocks.

Stacked end to end (in series) and side to side (in parallel), sarcomeres make up the length and width of muscle fibers. By imaging biceps muscles with three noninvasive methods, the researchers found that stroke patients had fewer sarcomeres along the length of the muscle fiber, resulting in a shorter overall muscle structure.

The research was published today (June 25) in the Proceedings of the National Academy of Arts and Sciences.

This finding is consistent with the common patient experience of abnormally tight, stiff muscles that resist stretching, and it suggests that changes in the muscle potentially amplify existing issues caused by stroke, which is a brain injury. The team hopes this discovery can help improve rehabilitation techniques to rebuild sarcomeres, ultimately helping to ease muscle tightening and shortening.

Amy N. Adkins et al, Serial sarcomere number is substantially decreased within the paretic biceps brachii in individuals with chronic hemiparetic stroke, Proceedings of the National Academy of Sciences (2021). DOI: 10.1073/pnas.2008597118

Comment by Dr. Krishna Kumari Challa on June 26, 2021 at 10:19am: Can you actually boost your immune system? Here's the truth

Take vitamin C supplements when you feel a cold coming on? The problem is, you can't actually "strengthen" your immune system, says Dr. Jen Gunter. Diving into the elegant network of cells, tissues and organs that protect us every day, she introduces two kinds of immunity that specialize in recognizing and fighting off bad bacteria, viruses, fungi and toxins -- and shares what you can do to keep your immune system healthy. Think you know how your body works? Think again! Dr. Jen Gunter is here to shake up everything you thought you knew -- from how much water you need to drink to how often you need to poop and everything in between.
