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!"

New treatment targets found for blinding retinal disease
When the eye isn't getting enough oxygen in the face of common conditions like premature birth or diabetes, it sets in motion a state of frenzied energy production that can ultimately result in blindness, and now scientists have identified new points where they may be able to calm the frenzy and instead enable recovery.In this high-energy environ, both the endothelial cells that will form new blood vessels in the retina—which could improve oxygen levels—and nearby microglia—a type of macrophage that typically keeps watch over the retina—prefer glycolysis as a means to turn glucose into their fuel.scientists have shown that in retinal disease, the excessive byproducts of this inefficient fuel production system initiate a crescendo of crosstalk between these two cell types. The talk promotes excessive inflammation and development of the classic mass of leaky, dysfunctional capillaries that can obstruct vision and lead to retinal detachment.The major byproduct of glycolysis is lactate, which also can be used as a fuel, for example, by our muscles in a strenuous workout. Microglia also need some lactate from the endothelial cells. But in disease, the lactate is in definite oversupply, which instead supports this destructive conversation between cellsThis is a major problem : loss of vision because of compromised oxygen for a variety of reasons. This additional insight into how that process destroys vision, will enable us to find better ways to intervene.In a low-oxygen environ, endothelial cells produce not only a lot of lactate, but also factors that encourage nearby microglia to be more active, and to use glycolysis to get more active.
In reality, microglia don't need the encouragement because they already also seem to prefer this method of energy production. But the extra lactate sent their way does spur them to produce even more energy and consequently even more lactate
The normally supportive immune cells also start overproducing inflammation-promoting factors like cytokines and growth factors that promote blood vessel growth or angiogenesis, which, in a vicious loop, further turns up glycolysis by the endothelial cells, which are now inclined to proliferate excessively.
"The reciprocal interaction between macrophages and (endothelial cells) promotes a feed-forward relationship that strongly augments angiogenesis," they write.
The destructive bottom line is termed pathological angiogenesis, a major cause of irreversible blindness in people of all ages, the scientists say, with problems like diabetic retinopathy, retinopathy of prematurity and age related macular degenration.
Our eyes clearly do not have sufficient oxygen, and they end up trying to generate more blood vesselsthrough this process called pathological angiogenesis, which is really hard to control.

Nanocatalysts that remotely control chemical reactions inside living cells
The enzymes responsible for catalytic reactions in our body's biological reactions are difficult to use for diagnosis or treatment as they react only to certain molecules or have low stability. Many researchers anticipate that if these issues are ameliorated or if artificial catalysts are developed to create a synergetic effect by meeting the enzymes in the body, there will be new ways to diagnose and treat diseases. In particular, if artificial catalysts that respond to external stimuli such as magnetic fields are developed, new treatment methods that remotely control bioreactions from outside the body can become a reality.

Biology:
1. Imaging method highlights new role for cellular 'skeleton' protein
While your skeleton helps your body to move, fine skeleton-like filaments within your cells likewise help cellular structures to move. Now, researchers have developed a new imaging method that lets them monitor a small subset of these filaments, called actin.
Until now, it's been really hard to tell where individual actin molecules of interest are, because it's difficult to separate the relevant signal from all the background."
With the new imaging technique, the researchers have been able to home in on how actin mediates an important function: helping the cellular "power stations" known as mitochondria divide in two. The work, which appeared in the journal Nature Methods on August 10, 2020, could provide a better understanding of mitochondrial dysfunction, which has been linked to cancer, aging, and neurodegenerative diseases.

4. Understanding vacuum fluctuations in space
An international research team of scientists has created structures in which light fields interact with electrons so strongly that the quantum vacuum itself is significantly altered. Using extremely short bursts of light, they interrupted this coupling much faster than the timescale of a vacuum fluctuation and observed an intriguing ringing of the emitted electromagnetic field, indicating the collapse of the vacuum state. Their key achievement could improve our understanding of the nature of nothingness—the vacuum of space itself, paving a way toward photonics exploiting vacuum fluctuations. The results are published in the current issue of Nature Photonics.

Physicists Demonstrate a Weird Effect Where Heating Particles Causes Them to Freeze!
https://www.sciencealert.com/physicists-demonstrated-a-weird-effect...
The idea of freezing particles by warming them is counterintuitive, to say the least. But physicists have shown how specially designed mixtures 'melt' in the dark but crystallise the moment the lights come on, thanks to their unique thermal activity.
Instead of bouncing the particles around and spreading them out, the researchers showed that by using light to heat up the mixture, they were able to lock particles in place and force them to clump together, as if they were frozen.
Researchers from the University of Cambridge in the UK carried out their experiments on a colloid made up of water, polystyrene and small droplets of oil coated in DNA to better understand the dynamics taking place between them when warmed by light.
particles suspended in a temperature gradient flow away from hot spots towards cooler ones.
So it'd stand to reason that if we heated suspensions of oil, focussing on the boundary with its watery surrounds, you would expect the mix of molecules to jiggle with excitement, bumping and grinding their way towards cooler areas and causing the fluids to move.
There's even a term for this oil and water flow; the Marangoni effect.
Putting it simply, the contrasting surface tension between oil and water makes each susceptible to variations in temperature in slightly different ways, forcing their particles to scatter.

Mpemba effect: Why hot water can freeze faster than cold
https://phys.org/news/2010-03-mpemba-effect-hot-faster-cold.html
Theories for the Mpemba effect have included:
- faster evaporation of hot water, which reduces the volume left to freeze
- formation of a frost layer on cold water, insulating it
- different concentrations of solutes such as carbon dioxide, which is driven off when the water is heated
The problem is that the effect does not always appear, and cold water often freezes faster than hot water.
Recent observations show supercooling is involved. water usually supercools at 0°C and only begins freezing below this temperature. The freezing point is governed by impurities in the water that seed ice crystal formation. Impurities such as dust, bacteria, and dissolved salts all have a characteristic nucleation temperature, and when several are present the freezing point is determined by the one with the highest nucleation temperature.
When researchers took two water samples at the same temperature and placed them in a freezer, they found that one would usually freeze before the other, presumably because of a slightly different mix of impurities. They then removed the samples from the freezer, warmed one to room temperature and the other to 80°C and then froze them again. The results were that if the difference in freezing point was at least 5°C, the one with the highest freezing point always froze before the other if it was heated to 80°C and then re-frozen.
The researchers said the hot water cools faster because of the bigger difference in temperature between the water and the freezer, and this helps it reach its freezing point before the cold water reaches its natural freezing point, which is at least 5°C lower. They also said all the conditions must be controlled, such as the location of the samples in the freezer, and the type of container, which they said other researchers had not done.
The effect now known as the Mpemba effect was first noted in the 4th century BC by Aristotle, and many scientists have noted the same phenomenon in the centuries since Aristotle’s time. It was dubbed the Mpemba effect in the 1960s when schoolboy Erasto Mpemba from Tanzania claimed in his science class that ice cream would freeze faster if it was heated first before being put in the freezer. The laughter ended only when a school inspector tried the experiment himself and vindicated him.

Sonocytology
How Do Our Cells Produce Sound?
The motion of molecular motors (motor proteins) in transporting cell organelles and setting the stage for cell activities like cell division, muscle contraction, etc. is believed to be root cause for cellular sounds. The study of the sounds of a cell is called sonocytology.
Well, not really, but your cells do sing and they might be able to give opera singers a run for their money.
Researchers in the year 2004 discovered that cells vibrate; when those vibrations are amplified, they sound like squeals. Also, each individual cell is thought to vibrate uniquely. Scientists argue that decoding these squeals could help us recognize the state of a cell and thus predict the arrival of a disease. This study of the sounds of a cell is called sonocytology (“sonos” ~ sound, “cytology” ~ study of cell structure and function).
