Nasal Vaccines Could Help Stop COVID-19 From Spreading—If Scientists Can Get Them Right

When SARS-CoV-2, the virus that causes COVID-19, infiltrates the body, it typically enters through the nose or mouth, then takes root and begins replicating. But what if it could never get a foothold in the upper airways and stopped by just inhaling a few drops of liquid or mist beforehand? That’s the idea behind nasal COVID-19 vaccines, which are meant to prevent infection by blocking the virus at its point of entry.

China Launched Crewed Mission To Complete Its Space Station Assembly

China on Sunday launched three astronauts into space as a part of its mission to complete assembly work on its permanent orbiting space station. The ‘Shenzhou 14’ crew blasted off from the Jiuquan Satellite Launch Center on the edge of the Gobi Desert at 10:44 a.m. (02:44 p.m. CST). The three astronauts will spend the next six months on China’s Tiangong space station, which translates to “heavenly palace.”

Electric Cars Being ‘Green’-It’s Complicated To Understand How?

Since the first modern electric vehicles (EV) took to the roads in the 2000s, critics have been quick to question the ‘clean’ label attached to them. From manufacturing concerns to battery power, EVs have been under scrutiny from skeptics. With the amount of debate and misinformation troubling the waters, the facts behind the efficiency of electric vehicles have become somewhat clouded – so just how clean are these vehicles?

Apple’s iPhone 14 Lineup: Everything You Need To Know About It

With the iPhone 14 release now just about three months away, we already have a pretty clear idea about what Apple’s next-gen iPhone is going to bring to the table. Suffice it to say, if you thought last year’s iPhone 13 lineup offered incremental improvements, the iPhone 14 may be just the device you’re waiting for.

A Cancer-Killing Virus Injected Into A Human For The First Time

An experimental cancer-killing virus has been administered to a human patient for the first time, with hopes the testing will ultimately reveal evidence of a new means of successfully fighting cancer tumors in people’s bodies. The drug candidate, called CF33-hNIS (aka Vaxinia), is what’s called an oncolytic virus, a genetically modified virus designed to selectively infect and kill cancer cells while sparing healthy ones.

Explained: The Reason Behind Different Colors Of Neptune And Uranus Despite Them Having Similar Sizes, Masses, and Atmospheric Compositions

Neptune and Uranus have much in common — they have similar masses, sizes, and atmospheric compositions — yet their appearances are in different shades of blue. At visible wavelengths, Neptune is a rich, deep azure hue, while Uranus is a distinctly pale shade of cyan. Astronomers now have an explanation for why the two planets are of different colors.

MonkeyPox: Everything You Should Know About It Before It’s Too Late

Nine people have died in Congo while Nigeria has recorded its first death from the latest MonkeyPox outbreak this year, even as at least 23 countries continue to grapple with the sudden spread of the disease. In its statement on Sunday, the World Health Organization said that the MonkeyPox virus has been spread to 23 non-endemic countries now, and there has so far been a cumulative total of 257 laboratory-confirmed cases and around 120 suspected cases.

Why Are Flagship Phones So Unpleasantly Expensive?

At the start of the last decade, smartphones weren’t so expensive. But it was also the same decade that flagship phones crossed the $1000 mark. And the uptrend doesn’t seem set to stop anytime soon. So, sure, flagship phones are getting expensive, but have you ever thought, why is that so? Are there some valid reasons behind it? Here are six key reasons why flagship phones are damn expensive:

How Does Mars Sound Like? NASA’s Perseverance Mars Rover Sends An Alien Soundscape That Changes With The Seasons

NASA scientists have cut down a year of Perseverance’s audio recordings on the Martian surface to a five-hour playlist of the Red Planet’s best hits (you can listen to some here). The sounds are eerily quiet and offer a new way of exploring the Martian environment. They’ve already helped confirm some theories about the way sounds travel on the planet.

Twitter-Elon Musk Circus: Shareholders Of The Social Media Company Are Seeking A Class-Action Lawsuit Against Billionaire Tesla Founder

In a new lawsuit, Twitter shareholders are suing Elon Musk, alleging that he manipulated the price of the company’s stock for his own benefit in the course of agreeing to buy the company. The lawsuit represents a group of Twitter investors but would allow any shareholders to receive financial compensation. The suit was filed on Wednesday night in federal district court for Northern California and argues that Musk intentionally drove down the company’s stock to secure a better deal.

The Smallest Remote-Controlled Walking Robot Ever Built

Engineers at Northwestern University in Evanston, Illinois, invented the world’s smallest remote-controlled walking robot, according to research published in the journal Science Robotics. It’s so small that it can crawl along the edge of a penny. Made of an elastic shape-memory alloy, the crab-shaped robot includes no hardware or electrical components. The research team hopes that its robotic design could be used in the future to perform tasks in extremely confined spaces.

DRAGON OF DEATH Found In Argentina

Imagine a winged dinosaur the size of a school bus casting a massive shadow over you as it swoops down to earth. Fossils of such a beast dubbed ‘the dragon of death’, have been unearthed by scientists. A study published online detailed the findings in the scientific journal Cretaceous Research. A reconstruction of the Pterosaur (the dragon of death)-and accompanying images on social media-displayed in Mendoza, Argentina, recently drew attention to the study.
