Researchers have made a major breakthrough using artificial intelligence that could revolutionize the hunt for new medicines. The scientists have created A.I. software that uses a protein’s DNA sequence to predict its three-dimensional structure to within an atomâ(TM)s width of accuracy. weiserfireman shares a report: The achievement, which solves a 50-year-old challenge in molecular biology, was accomplished by a team from DeepMind, the London-based artificial intelligence company that is part of Google parent Alphabet. Until now, DeepMind was best known for creating A.I. that could beat the best human players at the strategy game Go, a major milestone in computer science. DeepMind achieved the protein shape breakthrough in a biennial competition for algorithms that can be used to predict protein structures. The competition asks participants to take a protein’s DNA sequence and then use it to determine the protein’s three-dimensional shape. Across more than 100 proteins, DeepMind’s A.I. software, which it called AlphaFold 2, was able to predict the structure to within about an atom’s width of accuracy in two-thirds of cases and was highly accurate in most of the remaining one-third of cases, according to John Moult, a molecular biologist at the University of Maryland who is director of the competition, called the Critical Assessment of Structure Prediction, or CASP. It was far better than any other method in the competition, he said.

Bitcoin is back. Again. From a report: Nearly three years after it went on a hair-bending rise and hit a peak of $19,783, the price of a single Bitcoin rose above that for the first time on Monday, according to the data and news provider CoinDesk. The cryptocurrency has soared since March, after sinking below $4,000 at the outset of the coronavirus pandemic. Bitcoin’s latest climb is different from its last spike in 2017, which was driven largely by investors in Asia who had just learned about cryptocurrencies. Back then, the digital token soon lost momentum as people questioned what it could do other than allow for easy online speculating and drug and ransom payments.

While those questions remain, Bitcoin is now being fueled by a less speculative fever. Buyers — led by American investors, including companies and other traditional investors — are treating Bitcoin as an alternative asset, somewhat like gold, according to an analysis from the data firm Chainalysis. Rather than quickly trading in and out of it, more investors are using Bitcoin as a place to park part of their investment portfolios outside the influence of governments and the traditional financial system, Chainalysis and other industry firms said. “It’s a very different set of people who are buying Bitcoin recently,” said Philip Gradwell, the chief economist at Chainalysis, which analyzes the movement of cryptocurrencies. “They are doing it in steadier amounts over sustained periods of time, and they are taking it off exchanges and holding it as an investment.”

Facebook has acquired Kustomer, a New York-based software company that helps businesses manage customer conversations from multiple services on one dashboard. From a report: The social media giant made the deal to bolster its nascent messaging business, which is expanding to include customer-service products that help companies interact with people via chat apps, like WhatsApp and Messenger. “Any business knows that when the phone rings, they need to answer it. Increasingly, texts and messages have become just as important as that phone call — and businesses need to adapt,” Facebook executives wrote in a blog post. Kustomer also offers automated tools so companies can handle easier customer requests using bots. The deal values Kustomer at a little over $1 billion, WSJ reported.
