Ransomware Attacks Persists Even as High-Profile Cases Have Slowed

The Biden administration in September sanctioned a Russia-based virtual currency exchange that officials say helped ransomware gangs launder funds.

World Oceans Day 2021: Can we use bio-fouling organisms to extract energy from ocean waves?

Image
People living near the coast are familiar with the power of ocean waves. What we see when a typical wave breaks on a beach is the endpoint of a global energy conversion story. It starts with the sun’s heat driving winds whose energy generates ocean waves which grow and often travel thousands of kilometres. In this way, the ocean collects an enormous amount of energy. There’s enough energy in waves coming ashore that every metre of coastline could power around five average homes, and much more during storms. Capturing this energy is not a new idea, but one that faces many challenges. Our research illustrates the potential of enlisting biology in a reversal of the typical marine engineering view that “bio-fouling is bad”. Instead, it looks possible to use the added drag generated by allowing marine organisms to grow on a “naked” wave energy extractor. This model shows marine organisms could be used in wave energy extraction. Video by Christian Fischer. Decarbonising energy gener...

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

Image
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...

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....
