Starlink Will Hit 300Mbps and Expand To ‘Most of Earth’ This Year
Starlink broadband speeds will double to 300Mbps “later this year,” SpaceX CEO Elon Musk wrote on Twitter this week. SpaceX has been telling users to expect speeds of 50Mbps to 150Mbps since the beta began a few months ago. From a report: Musk also wrote that “latency will drop to ~20ms later this year.” This is no surprise, as SpaceX promised…

Happy birthday to Galileo, born February 15
One of our greatest astronomers, Galileo Galilei, was born February 15, 1564. His discoveries with the improved telescopes he made changed the way we view the universe – and got him in trouble with the church. Source: https://earthsky.org/human-world/galileos-birthday-feb-15-1564…
Bitcoin Consumes ‘More Electricity Than Argentina’
Thelasko shares a report from the BBC: Bitcoin uses more electricity annually than the whole of Argentina, analysis by Cambridge University suggests. ‘Mining’ for the cryptocurrency is power-hungry, involving heavy computer calculations to verify transactions. Cambridge researchers say it consumes around 121.36 terawatt-hours (TWh) a year — and is unlikely to fall unless the value of the currency slumps. Critics say…
Implementing a quantum approximate optimization algorithm on a 53-qubit NISQ device
A large team of researchers working with Google Inc. and affiliated with a host of institutions in the U.S., one in Germany and one in the Netherlands has implemented a quantum approximate optimization algorithm (QAOA) on a 53-qubit noisy intermediate-scale quantum (NISQ) device. In their paper published in the journal Nature Physics,, the group describes their method of studying the performance…
Evidence for substance at liquid-gas boundary on exoplanet WASP-31b
One of the properties that make a planet suitable for life is the presence of a weather system. Exoplanets are too far away to directly observe this, but astronomers can search for substances in the atmosphere that make a weather system possible. Researchers from SRON Netherlands Institute for Space Research and the University of Groningen have now found evidence on exoplanet…
Exxon Mobil To Invest $3 Billion In Carbon Capture and Other Projects To Lower Emissions
An anonymous reader quotes a report from The New York Times: Exxon Mobil, which has long been criticized by environmentalists and some investors and elected leaders for not doing enough to curb climate change, said on Monday it would invest $3 billion over the next five years in energy projects that lower emissions. The company said the first area it would…
Astronomers find possible exoplanet-in-the-making within its own whirlpool

Nintendo Sued by European Gamers Hampered by Broken Controllers
Nintendo faces a complaint from BEUC, a European consumer group, over what it calls “systematic problems” with the controllers for the company’s popular Switch games console. BEUC said it filed a complaint with the European Union and national consumer protection organizations after evidence from users showed that in 88% of cases, “the game controllers broke within the first two years.” A…
