SpaceX’s new Starlink satellite internet service is being touted as a rural internet game changer. WSJ spent time with a few beta testers in a very remote area of Washington state to see if it’s truly the solution to the global broadband gap. Photo Illustration: Laura Kammermann

Future Air Travel: ‘Lillium’ – 7-Seat Electric Vertical Take-Off & Land Jet (Video)
Lilium can revolutionize regional travel, saving people hours not minutes. Using its 7-Seater Lilium Jet, revealed March 30, 2021. Lilium’s regional shuttle service will enable sustainable, high-speed transportation. The 7-Seater Lilium Jet has market-leading capacity and is the first of Lilium’s serial aircraft.
It is capable of quiet vertical take-off, allowing Lilium access to more landing sites and the opportunity to build higher network density, avoiding the need for expensive ground infrastructure. The 7-Seater Lilium Jet and regional shuttle service business model are projected to deliver the best unit economics, with passenger and enterprise opportunities.
The Lilium 7-Seater Jet
The Lilium 7-Seater Jet has a projected cruise speed of 175 mph at 10,000 feet and a range of 155+ miles, including reserves. It is the culmination of five years of technology development across four generations of technology demonstrators, including Lilium’s full-scale 5-Seater.
Lilium applied for concurrent type certification for a high-capacity aircraft with EASA and the FAA in 2018. Development of the 7-Seater Lilium Jet began in stealth mode following this milestone. In 2020 the 7-Seater Lilium Jet received CRI-A01 certification basis from EASA.
Lilium has successfully developed, tested and refined the underlying technology for electric vertical take-off and landing jets – Lilium’s proprietary Ducted Electric Vectored Thrust (“DEVT”) technology, along with key control systems, aircraft and battery architecture. DEVT technology enables Lilium to scale to higher-capacity aircraft and keep noise emissions and ground footprint low.
Analysis: Are Delivery Apps Good For Restaurants?
While indoor dining has dropped way down during the pandemic, food delivery has grown considerably. DoorDash and Uber Eats, the two largest delivery apps by market share both saw their sales double from the end of 2019 to the end of 2020.
But while it might be an easy decision for customers to use these third-party delivery apps, the decision for restaurants is not so easy. There is a lot to consider, and it’s not a one-size-fits-all solution.
Cryptocurrency: The Challenges Facing New ‘Stablecoins’ (WSJ Video)
Bitcoin’s volatility has limited its adoption for payments, so entrepreneurs created stablecoins: cryptocurrencies pegged to assets such as the U.S. dollar. But the recent settlement of a probe into the most popular stablecoin, tether, shows the need for transparency in the growing industry. Photo illustration: Sharon Shi/WSJ
Biotechnology: ‘mRNA Could Change The World’
The dream of mRNA persevered in part because its core principle was tantalizingly simple, even beautiful: The world’s most powerful drug factory might be inside all of us.
Like so many breakthroughs, this apparent overnight success was many decades in the making. More than 40 years had passed between the 1970s, when a Hungarian scientist pioneered early mRNA research, and the day the first authorized mRNA vaccine was administered in the United States, on December 14, 2020. In the interim, the idea’s long road to viability nearly destroyed several careers and almost bankrupted several companies.

Studies: ‘Coffee’ – Machine Learning Review Shows Benefits Of Drinking It
“It may be good for you,” says Dariush Mozaffarian, dean of the Friedman School of Nutrition Science and Policy at Tufts University. “I think we can say with good certainty it’s not bad for you.” (Additives are another story.)
After the link appeared between coffee intake and a reduced risk of heart failure in the Framingham data, Kao confirmed the result by using the algorithm to correctly predict the relationship between coffee intake and heart failure in two other respected data sets. Kosorok describes the approach as “thoughtful” and says that it “seems like pretty good evidence.”
Should you drink coffee? If so, how much? These seem like questions that a society able to create vaccines for a new respiratory virus within a year should have no trouble answering. And yet the scientific literature on coffee illustrates a frustration that readers, not to mention plenty of researchers, have with nutrition studies: The conclusions are always changing, and they frequently contradict one another.
Naval Warfare: The New British ‘Dreadnought Class Submarine’ (Video)
The Dreadnought class of submarines will replace Britain’s existing fleet of Vanguards when they enter service from the early 2030s. Built by BAE and Rolls-Royce, the Dreadnought will have a payload of 16 nuclear missiles and torpedoes.
