Two examples of deeply flawed logic:
You don’t have dandruff. So why do you use dandruff shampoo?
We don’t have many cases of COVID-19. So why should we keep our State closed?
Scientists have achieved the restorative benefits of deep sleep in awake mice, without them actually sleeping. In a groundbreaking study published in Nature Neuroscience, researchers at the University of Wisconsin-Madison used optogenetics, a technique that uses light to control genetically modified neurons, to induce slow-wave “on/off” patterns characteristic of non-REM sleep in localized regions of the animals’ brains.
Sleep-deprived but active mice that received this artificial stimulation performed as well on memory and learning tasks as fully rested mice. The results support the idea that specific neural activity patterns, rather than unconsciousness itself, drive synaptic restoration and cognitive recovery.
This discovery suggests it may one day be possible to develop targeted therapies that counteract the effects of sleep deprivation and help treat cognitive decline in humans.

Infrared Jupiter!
An infrared image of the giant of our Solar System. Details of the planet's atmosphere, the Great Red Spot (though it's white here), Jupiter's thin rings, auroras, and two moons—Amalthea and Adrastea—are clearly visible.
And also diffraction spikes, which are caused by the optics of telescopes and originate from bright objects. Here we see diffraction from the auroras and from the moon Io, which is off-frame to the left.
Flying to the center of the galaxy.
This animation is composed of observations from various telescopes. It begins with a 360-degree panorama of the Milky Way and ends at the very center of the galaxy, where observations from the VLT, collected over many years, reveal the motion of S-type stars. They orbit at incredible speed around an invisible object—the supermassive black hole Sagittarius A*.
@ashug98@ananyashasau That's not the point. You should understand the mentality of Indian people as well. They will use no common sense and will throw wet garbage in it and it will lead to insect and all and then again Govt to be blame for. Travellers has to be more sensible or not possible
@ananyashasau Stop calling out for the things just because you needed more privilege on your seat. If you don't like it, then don't travel in train. Learn to appreciate something in life.
@ananyashasau Bahen tujhe sab hath me chahiye. How uneducated you are. there is always a dustbin at the door, if you don't know. Just move your ass to go to the dustbin. It will people like you only bitching about having dustbin near every corner later on. so don't try to dig everything
This incredible image shows a thin section of a supernova remnant caused by a stellar explosion that occurred more than 1,000 years ago!

@MukAn_X Such people doesn't have basic etiquette, zero civics sensex no manners or morals. I don't know what they might be doing at home with such attitudes. Pitty for their family and his kids. This attitude will take him no where. Sick
