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!"

When light and atoms share a common vibe- explained below
**
1. A laser generates a very short pulse of light 2. A fraction of this pulse is sent to a nonlinear device to change its color 3. The two laser pulses overlap on the same path again, creating a “write & read” pair of pulses. 4. Each pair is split into a short and a long path, 5. yielding an “early” and a “late” time slot, overlapping once again 6. Inside the diamond, during the “early” time slot, one photon from the “write” pulse may generate a vibration, while one photon from the “read” pulse converts the vibration back into light. 7. The same sequence may also happen during the “late” slot. But in this experiment, the scientists made sure that only one vibration is excited in total (in both early and late time slots). 8. By overlapping the photons in time again it becomes impossible to discriminate the early vs. late moment of the vibration. The vibration is now in a quantum superposition of early and late time. 9. In the detection apparatus, “write” and “read” photons are separated according to their different colors, and analyzed with single-photon counters to reveal their entanglement.

When light and atoms share a common vibe
An especially counter-intuitive feature of quantum mechanics is that a single event can exist in a state of superposition – happening both here and there, or both today and tomorrow.
Such superpositions are hard to create, as they are destroyed if any kind of information about the place and time of the event leaks into the surrounding – and even if nobody actually records this information. But when superpositions do occur, they lead to observations that are very different from that of classical physics, questioning down to our very understanding of space and time.
Scientists demonstrated a state of vibration that exists simultaneously at two different times, and evidence this quantum superposition by measuring the strongest class of quantum correlations between light beams that interact with the vibration.
The researchers used a very short laser-pulse to trigger a specific pattern of vibration inside a diamond crystal. Each pair of neighboring atoms oscillated like two masses linked by a spring, and this oscillation was synchronous across the entire illuminated region. To conserve energy during this process, a light of a new color is emitted, shifted toward the red of the spectrum.
This classical picture, however, is inconsistent with the experiments. Instead, both light and vibration should be described as particles, or quanta: light energy is quantized into discrete photons while vibrational energy is quantized into discrete phonons (named after the ancient Greek “photo = light” and “phono = sound”).
The process described above should therefore be seen as the fission of an incoming photon from the laser into a pair of photon and phonon – akin to nuclear fission of an atom into two smaller pieces.
But it is not the only shortcoming of classical physics. In quantum mechanics, particles can exist in a superposition state, like the famous Schrödinger cat being alive and dead at the same time.
Even more counterintuitive: two particles can become entangled, losing their individuality. The only information that can be collected about them concerns their common correlations. Because both particles are described by a common state (the wavefunction), these correlations are stronger than what is possible in classical physics. It can be demonstrated by performing appropriate measurements on the two particles. If the results violate a classical limit, one can be sure they were entangled.
In the new study, EPFL researchers managed to entangle the photon and the phonon (i.e., light and vibration) produced in the fission of an incoming laser photon inside the crystal. To do so, the scientists designed an experiment in which the photon-phonon pair could be created at two different instants. Classically, it would result in a situation where the pair is created at time t1 with 50% probability, or at a later time t2 with 50% probability.
But here comes the “trick” played by the researchers to generate an entangled state. By a precise arrangement of the experiment, they ensured that not even the faintest trace of the light-vibration pair creation time (t1 vs. t2) was left in the universe. In other words, they erased information about t1 and t2. Quantum mechanics then predicts that the phonon-photon pair becomes entangled, and exists in a superposition of time t1andt2. This prediction was beautifully confirmed by the measurements, which yielded results incompatible with the classical probabilistic theory.
By showing entanglement between light and vibration in a crystal that one could hold in their finger during the experiment, the new study creates a bridge between our daily experience and the fascinating realm of quantum mechanics.

Different people will show different views on the best science breakthroughs of the year. We present some of them here.
One such view: The biggest and most important scientific breakthroughs of 2020

There’s no magic way to boost your energy. But ‘perineum sunning’ isn’t the answer
Perineum sunning is said to have roots in an ancient Taoist practice, where the perineum, or “Hui Yin”, is regarded as a gateway where energy enters and exits the body.
It’s probably also related to the idea that the sun has healing powers. Many years ago sun exposure was recommended after childbirth, and sunlamps were used in labour wards to ostensibly aid healing. But there was no evidence for this.
Some of the appeal of the trend might also lie in the fact many pale-skinned people like to be tanned.
That said, tanning is not the motivation behind the perineum sunning wellness trend. People who do it say it gives their body an intense dose of vitamin D, and therefore a significant energy boost.
It can also supposedly increase creativity, improve sleep, and even promote a healthy libido, among other reported benefits.

But there’s no evidence to support any of these supposed benefits. Although there have been no scientific studies on perineum sunning to date.
However, we can’t dismiss the placebo effect. For example, if someone thinks sunning their perineum will improve their libido, it probably will.
The main risk of perineum sunning is sunburn. Sun-exposed skin adapts to exposure to ultraviolet (UV) light by forming melanin, the natural protective pigment in skin that reduces the risk of sunburn. So when you get UV light on a part of your skin that’s not accustomed to sun exposure, you’re much more likely to get burnt.
If you do get sunburnt in this sensitive area, it’s likely to be very sore. You won’t be able to have sex for about a week, and it might sting to urinate.
And of course, UV is a known carcinogen, which is why nowadays we discourage any kind of tanning. Sunburn can increase your risk of skin cancer, and chronic UV exposure can raise skin cancer risk even without causing sunburn.

If you were asked to draw a picture of your grandparents' living room from memory, could you do it? For most people, certain details are easy to visualize: "There's a piano in the corner, a palm by the window and two seashells on the coffee table."
But for others, such a task would be almost impossible. These individuals have a rare condition called aphantasia, which prevents them from easily recreating images in their mind's eye—in fact, the phrase "mind's eye" may be meaningless to them.
"Some individuals with aphantasia have reported that they don't understand what it means to 'count sheep' before going to bed." They thought it was merely an expression, and had never realized until adulthood that other people could actually visualize sheep without seeing them.
The differences in the memory experiment were striking: Individuals with typical imagery usually drew the most salient objects in the room with a moderate amount of detail, like color and key design elements (a green carpet, rather than a rectangle).
Individuals with aphantasia had a harder time—they could place a few objects in the room, but their drawings were often simpler, and relied at times on written descriptions. For example, some wrote the word "window" inside an outline of a window rather than drawing the windowpanes.
While people with aphantasia lack visual imagery, they appear to have intact spatial memory, which is distinct from imagery and may be stored differently . People who are congenitally blind, for example, can still describe the layout of a familiar room.
even though people with aphantasia remembered fewer objects overall, they also made fewer mistakes: They didn't create any false memories of objects that hadn't been in any of the rooms, and placed objects in the correct location—but the wrong room—only three times.
"One possible explanation could be that because aphantasics have trouble with this task, they rely on other strategies like verbal-coding of the space. Their verbal representations and other compensatory strategies might actually make them better at avoiding false memories."

Astrocytes eat connections to maintain plasticity in adult brainsDeveloping brains constantly sprout new neuronal connections called synapses as they learn and remember. Important connections—the ones that are repeatedly introduced, such as how to avoid danger—are nurtured and reinforced, while connections deemed unnecessary are pruned away. Adult brains undergo similar pruning, but it was unclear how or why synapses in the adult brain get eliminated. |

Love and hate in the mouse brainMounting behavior, that awkward thrusting motion dogs sometimes do against your leg, is usually associated with sexual arousal in animals, but this is not always the case. New research by Caltech neuroscientists that explores the motivations behind mounting behavior in mice finds that sometimes there is a thin line between love and hate (or anger) in the mouse brain. ** |
