Here’s your wrap of the latest technology, innovation, and finance news.
A new picture of a black hole
unveiled a swirling magnetic field (see the first paperand the second paper).
“This jet process is totally amazing – something the size of our solar system can shoot out a jet that pierces through entire galaxies and even galaxy neighborhoods,” says Issaoun. “Now we’re really seeing the magnetic field close to the black hole for the first time, and that’s connecting it to the jet, which is the most powerful process in the universe.”
NASA is getting ready for its first helicopter flight on Mars, which will take place on April 8th at the earliest.
“It will have 31 Earth days to attempt to be the first helicopter to fly on another planet,” said Lori Glaze, director of NASA’s planetary science division. “It isn’t intended to collect science, but because its mission is so focused, it is, at its core, innovative.”
Where did the water on Mars go? A
recent paper suggests that most of it may still be there.
But most of the water, a new study concludes, went down, sucked into the red planet’s rocks. And there it remains, trapped within minerals and salts. Indeed, as much as 99 percent of the water that once flowed on Mars could still be there, the researchers estimated in a paper published this week in the journal Science.
It turns out a
meteor shower over Portland wasn’t a meteor shower after all; it was space debris from a SpaceX rocket.
? Chips and Computing
The WSJ looks at the materials that could replace silicon in future tech.
Researchers on the bleeding edge of physics, chemistry and engineering are experimenting with exotic-sounding substances to be used in microchips. They include graphene, black phosphorus, transition metal dichalcogenides, and boron nitride nanosheets. Collectively, they’re known as 2-D materials, since they are flat sheets only an atom or two thick. Largely unknown just 20 years ago, they are now regularly fabricated in labs, using methods as mundane as a blender and as tricky as high-temperature vapor deposition.
Intel’s new CEO, Pat Gelsinger, delivered an
excellent keynote outlining Intel’s strategy going forward — it’s 59 minutes long but worth the watch if you’re interested in semiconductors or computing. Stratechery’s breakdown is also worth a read.
? Blockchain and Crypto
The New York Times article
Buy This Column on the Blockchain! was indeed bought on the blockchain for $560,000.
The NFT, a unique bit of digital code that is stored on the Ethereum blockchain and refers to a 14 megabyte graphic of the column hosted on a decentralized file hosting service, cannot be duplicated or counterfeited, making it potentially valuable for collectors. Some NFTs have sold for hundreds of thousands of dollars in recent weeks, with one such sale — a
collection of art by the digital artist Beeple — bringing in more than $69 million at auction.
Chainalysis, a start-up that sells blockchain data analytics tools, has doubled its valuation to $2 billion in a new investment round.
Founded in 2014, Chainalysis helps governments and private sector companies detect and prevent the use of bitcoin and other cryptocurrencies in illicit activities like money laundering with its investigations and compliance software.
Bitcoin is being increasingly used for money remittance by the
millions of workers who send their earnings abroad.
Nowhere is this clearer than in Nigeria, where the central bank is so worried about Nigerians choosing cryptocurrencies over the naira for overseas remittance payments that it is now
paying them to use official channels for those transfers instead.
A report released by the National Academies of Sciences, Engineering and Medicine recommends more investment into solar geoengineering research, where sunlight is reflected back to space to artificially cool the planet.
So far, it’s a purely hypothetical idea — but scientists have proposed a number of ways it could be done.
The most common proposal suggests spraying reflective aerosols into the atmosphere, where they would beam sunlight away from the Earth. Other proposals involve making clouds brighter by injecting them with particles, or to help trap less heat beneath them.
They’re contentious ideas. Experts have many concerns about the possibility of unintended consequences, such as unwanted effects on rainfall or other global weather patterns.
California scientists are looking into
covering canals with solar panels.
study, published in the journal Nature Sustainability, finds that if applied statewide, the panels would save 63 billion gallons of water from evaporating each year. At the same time, solar panels across California’s exposed canals would provide 13 gigawatts of renewable power annually, about half of the new capacity the state needs to meet its decarbonization goals by the year 2030.

Google’s top security team has thwarted a nine-month hacking operation, however, it’s a
counterterrorism hacking operation undertaken by a US ally, highlighting the complexity of balancing user security with national security concerns.
Instead of focusing on who was behind and targeted by a specific operation, Google decided to take broader action for everyone. The justification was that even if a Western government was the one exploiting those vulnerabilities today, it will eventually be used by others, and so the right choice is always to fix the flaw today.
Facebook says it
blocked hackers in China who were trying to spy on Uyghur Muslims abroad.
Facebook said it found websites designed to look like third-party Android app stores “where they published Uyghur-themed applications, including a keyboard app, prayer app, and dictionary app.” Any apps downloaded from these sites contained malicious software to infect devices.
A Florida student and her mother were arrested after hacking school records to
steal the homecoming queen election. ? Robotics
A New York lawmaker has proposed a law that will
ban police use of armed robots in the future.
New York City councilmember Ben Kallos says he “watched in horror” last month when city police
responded to a hostage situation in the Bronx using Boston Dynamics’ Digidog, a remotely operated robotic dog equipped with surveillance cameras. Pictures of the Digidog went viral on Twitter, in part due to their uncanny resemblance with world-ending machines in the Netflix sci-fi series Black Mirror.
