22.jpgCrypto entrepreneur Sina Estavi made headlines in March 2021 when he paid $2.9m for an NFT of Twitter boss Jack Dorsey’s first tweet. But his efforts to resell it have run aground, with a top bid of just $6,800 as of Thursday. While announcing the NFT sale in a tweet on 6 April, Estavi pledged to give 50% of the proceeds – which he expected to be at least $25m – to charity.

NY times: New York beaches are stepping up shark patrols — including the use of drones and online shark tracking — amid an increase in sightings. And: Scientists say the reason it may seem like more sharks are being spotted is because more people are looking for them.

Ten years ago scientists announced one of the most momentous discoveries in physics: the Higgs boson. The particle, predicted 48 years earlier, was the missing piece in the Standard Model of particle physics. The machine built in part to find this particle, the 27-kilometer-long, circular Large Hadron Collider (LHC) at CERN near Geneva, had fulfilled its promise by showing signals of a new fundamental bit of nature that matched expectations for the Higgs. —- How the Higgs Boson Ruined Peter Higgs’s Life

The Large Hadron Collider (LHC) has observed three never-before-seen particles: a new kind of “pentaquark” and the first-ever pair of “tetraquarks”

Quantum Computing for Dummies — Whereas classical computers switch transistors either on or off to symbolize data as ones or zeroes, quantum computers use quantum bits, or “qubits,” which because of the peculiar nature of quantum physics can exist in a state called superposition where they are both 1 and 0 at the same time. This essentially lets each qubit perform two calculations at once. The more qubits are quantum-mechanically linked, or entangled, within a quantum computer, the greater its computational power can grow, in an exponential fashion.

Information could become the fifth state of matter alongside gas, plasma, liquid, and solid states. A scientist has proposed an experiment involving particle annihilation that could establish that information truly has mass. If successful, the experiment could shed light on the mysterious dark matter in our universe—and help us manage the future of data storage.
