Repeated 51 percent attacks on proof-of-work (PoW) cryptocurrencies have triggered a critical dialogue about the security of blockchain networks. Last week, a researcher showed that a cryptocurrency worth $2 billion can be hacked profitably with as little as $1.5 million. One cryptocurrency enthusiast decided to take a deeper dive. Reddit user xur17 has created crypto51.app, a website that tracks the costs of performing hourly 51 percent attacks on PoW cryptocurrencies. The results are startling. As per the website calculations, it will only take $2,990 to keep an attack going on Bitcoin Gold for one hour, $2,216 on Ethereum Classic, $1,124…

On November 5th 1955 the fictional Doctor Emmitt Brown was hanging a clock in his bathroom when he slipped and hit his head on the side of a sink. As he recovered from the blow, he had a vision: he would build the flux capacitor and thereby make time travel possible. A not-fictional team of scientists from Australia and Switzerland recently invented one in real life. But don’t go nuts: it breaks time-reversal symmetry, but it does not make time travel possible. What it does: The real-life flux capacitor is like a tuning fork for quantum systems. It channels microwaves…

Researchers at the University Of Newcastle have announced they’ve managed to 3D print corneas – the outermost part of the human eye. This is incredible, life-changing news for a lot of folks. Worldwide, 10 million people require surgery to prevent corneal blindness from diseases like trachoma. On top of this, almost 5 million are completely blind due to corneal scarring from accidents or illnesses. This high-tech method of producing corneas could end all that. It works by taking stem cells from a health donor’s cornea and mixing it together with a gel, creating what researchers have deemed “bio-ink.” “Our unique…
