Both COVID-19 vaccine doses needed for good protection against B16172 variant

It’s been a concerning few weeks in the UK, with the B16172 variant first taking hold and then spreading to become dominant. This more infectious form of the virus, initially identified in India, is what we’re now going to have to live with – unless it is out-competed by another variant in the future. Worryingly, experts had predicted that B16172 might be able to escape some of the effects of vaccines, which if true would threaten to derail the UK’s plans to finish lifting restrictions from the end of June. However, Public Health England (PHE) has looked at the ability of various variants to evade immunity and says that the UK’s vaccines remain effective against the variants circulating, including B16172. On the surface, this looks like good news. But delve a bit deeper, and things get more complicated, says Paul Hunter, professor of medicine at the University of East Anglia. PHE’s research found a little drop-off in protection against B16172 among people who were fully vaccinated....

After GameStop, the rise of Dogecoin shows us how memes can move markets

One of the most difficult problems in finance right now is figuring out the fundamental economic value of cryptocurrencies. And the past week has complicated this further. For many cryptocurrency investors, the value of Bitcoin is based on the fact it is artificially scarce. A hard cap on “ minting ” new coins means there will only ever be 21 million Bitcoin in existence. And unlike national currencies such as the Australian dollar, the rate of release for new Bitcoin is slowing down over time. Dogecoin, a cryptocurrency that takes its name and logo from a Shiba Inu meme that was popular several years ago, doesn’t have a cap. Launched in 2013, there are now 100 billion Dogecoin in existence, with as many as five billion new coins minted each year. But how can a currency with a seemingly unlimited supply have any value at all? And why did Dogecoin’s price suddenly surge more than 800 percent  in 24 hours on 29 January? At the time of publication, the “memecoin” was worth abou...

NASA is planning to partner with SpaceX to reboost the Hubble Telescope and extend its life

The Hubble Space Telescope is one of the most important scientific achievements of the human species that has helped us understand space. It has been in orbit for over 30 years and has been feeding some of the most vital streams of information that has not only helped us steer our space exploration efforts, but also solve some of the more deep mysteries of the universe . NASA would love to extend its usable life for as long as possible. Unfortunately, for some years now, Hubble Space Telescope has been slipping out of its orbit. That is why, NASA is planning to team up with Elon Musk’s SpaceX and place it into a higher much more stable orbit. NASA, SpaceX and Jared Isaacman, a private astronaut with the Polaris Program, hosted a media teleconference on Thursday to announce a feasibility study that will look into sending a commercial Dragon spacecraft to reboost the Hubble Space Telescope . This will, in effect place the telescope into a higher and more stable orbit than it’s curren...
