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!"

"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!

Comment by Dr. Krishna Kumari Challa 3 hours ago: New hydrogel can repair tears in human tissue

Scientists have developed an injectable gel that can attach to various kinds of soft internal tissues and repair tears resulting from an accident or trauma.

Comment by Dr. Krishna Kumari Challa 3 hours ago: Streams and rivers emit more carbon dioxide at night than day

Streams and rivers emit large amounts of carbon dioxide into the atmosphere, but a new study published in Nature Geoscience led by researchers at the universities in Umeå and Lausanne shows that the flux may be greater than previously thought.

Current estimates of carbon dioxide emissions from running water are based on manual samples, where a person goes to the river, takes a sample and analyzes the content of carbon dioxide in the water. But by doing this, we had previously assumed that concentrations are stable over time. In the last decade, there has been a revolution in sensor technology and now we can measure water parameters continuously in the water and know how variable are over time.

In the current study, an international research team led by Lluis Gomez-Gener at the École polytechnique fédérale de Lausanne, Gerard Rocher-Ros and Ryan Sponseller at Umeå University has used the power of sensors to measure carbon dioxide in rivers and streams at a high-resolution. They found that carbon dioxide emissions during the night were greater than during the day.

These results are of great importance for our understanding of the role of rivers and streams in the global carbon cycle, as previous estimates, based on manual samples during the day, underestimated the actual flux.

Comment by Dr. Krishna Kumari Challa 4 hours ago: Fit matters most when double masking to protect yourself from COVID-19

A study published today in JAMA Internal Medicine shows that wearing two face coverings can nearly double the effectiveness of filtering out SARS-CoV-2-sized particles, preventing them from reaching the wearer's nose and mouth and causing COVID-19. The reason for the enhanced filtration isn't so much adding layers of cloth, but eliminating any gaps or poor-fitting areas of a mask.

The medical procedure masks are designed to have very good filtration potential based on their material, but the way they fit our faces isn't perfect.

According to their findings, the baseline fitted filtration efficiency (FFE) of a mask differs person to person, due to each person's unique face and mask fit. But generally, a procedure mask without altering the fit, is about 40-60% effective at keeping COVID-19-sized particles out. A cloth mask is about 40% effective.

Recent findings on doubling of face masks, shows that when a cloth mask is placed over a surgical mask, the FFE improved by about 20%, and improved even more with a snug-fitting, sleeve-type mask, such as a gaiter. When layered over procedure masks, cloth masks improve fit by eliminating gaps and holding the procedure mask closer to the face, consistently covering the nose and mouth. When a procedure mask is worn over a cloth mask, FFE improved by 16%.

It was found that wearing two loosely fitted masks will not give you the filtration benefit that one, snug-fitting procedure mask will.

Comment by Dr. Krishna Kumari Challa 4 hours ago: Sweat sensor could alert doctors, patients to looming COVID cytokine storm

Early in the COVID-19 pandemic, doctors recognized that patients who developed a "cytokine storm"—a surge of pro-inflammatory immune proteins—were often the sickest and at highest risk of dying. But a cytokine storm can also occur in other illnesses, such as influenza. Today, scientists report preliminary results on a sweat sensor that acts as an early warning system for an impending cytokine storm, which could help doctors more effectively treat patients.

Comment by Dr. Krishna Kumari Challa 23 hours ago: Is a calorie always a calorie? Not when it comes to almonds, researchers find

Researchers have found that a calorie labelled is not the same as a calorie digested and absorbed when the food source is almonds.

The findings, published in the journal Mayo Clinic Proceedings, should help alleviate concerns that almonds contribute to weight gain, which persist despite the widely recognized benefits of nuts as a plant-based source of protein, vitamins and minerals.

Nuts have generally been thought of as healthy the last two decades, but the messaging around nuts has often come with a disclaimer that they are high in fat and energy. We still see that caveat in the media and on the internet today, and it has been part of many clinical guidelines, although that is changing.

Other researchers have shown that there is a bioaccessibility issue with nuts – that a calorie labelled may not be a calorie absorbed. This study quantifies that effect with almonds in a relevant population.

The researchers found that after digestion, about 20 per cent of calories derived largely from fat in almonds remained unabsorbed, which they observed in stool samples. That translated to about two per cent less energy absorbed from the diet overall among study participants.

A person eating the same amount of almonds in a daily diet of 2,000 to 3,000 calories would absorb 40 to 60 calories less than would be predicted by Atwater factors, on which many food labels are based. That could result in weight loss up to 2.9 kilograms, or 6.3 pounds, over a year, assuming no compensation in the form of increased intake or decreased energy expenditure.

Participants in the study did not gain weight, which is consistent with the majority of high-quality trials that measure nut consumption and weight gain – some of which show an association with weight loss.

The researchers used a randomized crossover trial to study 22 women and men with high cholesterol who underwent a series of three, month-long dietary interventions separated by a week-long washout period.

All study participants consumed an NCEP Step-2 diet (low in saturated fat and cholesterol, part of the U.S. National Cholesterol Education Program). The three dietary interventions were full-dose almonds (75 grams per day or three quarters of a cup); half-dose almonds plus half-dose muffins; and full-dose muffins as a study control. The nutritional makeup of the muffins matched the almonds in amount of protein, fibre and fats.

One unique aspect of this study is that it assessed people with high cholesterol, who are at greater risk for cardiovascular disease.
