The letter sent to the SEC

Elon Musk announced that he terminated the deal to buy Twitter he signed at the end of April 2022 for a value of approximately $44 billion. The billionaire claims that the social network executives didn’t provide the data required by the agreement, in particular those relating to the fake profiles used by spammers. His position was explained in a letter sent on his behalf by a lawyer to the Securities and Exchange Commission (SEC), the authority that oversees the American stock exchange. Twitter executives have announced plans to sue Elon Musk, so the story is far from over.

An article published in the journal “Genome Biology” reports the results of tests conducted with SeqScreen, a free / open source software developed to recognize genetic sequences existing in pathogenic microorganisms. A team of researchers led by computer scientist Todd Treangen of Rice University and genomics specialist Krista Ternus of the scientific consultancy firm Signature Science, LLC developed SeqScreen to analyze the characteristics of short DNA sequences often called oligonucleotides and improve the recognition techniques of sequences present in a sample that are at least potentially dangerous.

The American Frontier supercomputer has been crowned the new king of the Top 500 ranking. It has a speed that is more than twice that of the Japanese Fugaku, the previous king. This is the first exascale supercomputer, which means that it’s capable of exceeding the calculation capacity of 1 exaflop with 10^18 floating point operations per second. Frontier reaches 1.102 exaflops per second.

Elon Musk's tweet about free speech

Twitter’s board of directors accepted Elon Musk’s offer to buy the social network for $54.2 a share in a $44 billion deal. One consequence will be that Twitter will be a private company again leaving the Wall Street Stock Exchange. In early April, Musk bought 9.2% of the social network but decided not to join its board. Now, his stated goal is to change Twitter to ensure free speech, which he sees as a bedrock of democracy.
