Coronavirus: Dexamethasone reduces the mortality rate of (critically) ill patients. Why is the medical world excited about it? Because the cheap and widely available steroid is a potential life-saving drug for critically ill COVID-19 patients. That’s what the researchers at the University of Oxford discovered. In their study, the drug has been found to reduce the mortality of the sickest patients. Which is more like virtually pulling them away from the doorstep of death. The medication is of no use to corona patients with mild symptoms, but that doesn’t matter. They don’t require hospitalisation. No medicines too, as their treatment is more symptomatic. Critically ill patients COVID-19 patients are generally hospitalised only when their lungs are affected. They will require assisted breathing. A patient on a ventilator is at a critical stage. So when a drug reduces deaths by one-third, that is enough cause for jubilation. It’s a life-saver! Until now, there have...

The research team s approach uses simple assumptions for how life developed,, assuming that intelligent life formed in a similar way like that on Earth. Our galaxy may have 36 active communicating intelligent civilizations, according to research by a team from the University of Nottingham, UK. As per the study, the average distance to the nearest of these civilizations would be 17,000 light-years which makes the detection and communication very difficult with the current technology, according to Advanced Science News. The research team's approach uses simple assumptions for how life developed, assuming that intelligent life formed in a similar way like that on Earth.There should be at least a few dozen active civilizations in our Galaxy under the assumption that it takes 5 billion years for intelligent life to form on other planets, as on Earth,,, Advanced Science News quoted team lead Christopher Conselice as saying.  It is clear that the lifetime of a comm...

At least 20 Indian soldiers killed in the violent face-off with China in Galwan valley in Eastern Ladakh. Casualty numbers could rise: Government Sources. Can confirm that the Indian Army fatality number in the # GalwanValley clash is more than 20.

Army sources say the soldiers were not shot but were killed in hand-to-hand combat on Indian Territory. hile, Beijing urged India to “strictly restrain its frontline troops from crossing the border or taking any unilateral action that may complicate the border situation”. Punjab Chief Minister Captain Amarinder Singh called for a strong response from the Centre to the repeated incursions by the Chinese into Indian territory while Congress demanded that all political parties be briefed on the ground situation. The last deaths at the  Line of Actual Control  (LAC) were in 1975 when an Indian patrol was ambushed by Chinese soldiers in Arunachal Pradesh. A violent clash between the two sides on the border had taken place at Nathu La in 1967.

Researchers enlisted quantum physics to send a secret key for encrypting and decrypting messages between two stations 700 miles apart. “secret key for encrypting The world of artificial satellites, silent in the void of space, might seem pacific. In fact it’s a high-flying battlefield rife with jamming, snooping, blinding, spoofing, hacking and hostility among the planet’s growing array of spacecraft and space powers. Now, Chinese scientists report new progress in building what appears to be the first unbreakable information link between an orbiting craft and its terrestrial controllers, raising the odds that Beijing may one day possess a super-secure global communications network. In the journal Nature on Monday, the team of 24 scientists  describe successfully testing  the transmission of a “secret key” for encrypting and decrypting messages between a satellite and two ground stations located roughly 700 miles apart. The method enlists  quantum entanglement...
