Chinese researchers say they have made a breakthrough in laser propulsion technology that could one day be used on submarines and missiles. A laser propulsion expert at McGill University told Business Insider they see flaws in the claims. Rather than relying on nuclear or battery power, the scientists say they have found a way to use lasers to propel submarines — known as underwater laser propulsion. This technology has already been used in Russian Shkval torpedoes since the 1970s, using rocket exhaust rather than laser power. "The average overall thrust is low and the jet power cannot exceed the power supply of the laser."

Chinese submarine crews are training to operate farther into the Western Pacific. AdvertisementChina is forcing its submarine crews to endure more intensive and realistic training exercises. Ironically, while rigorous training is intended to create a more skilled and aggressive submarine force, these changes could backfire. "What the literature does suggest is that the PLAN submarine force is simultaneously incorporating a wide range of new operational guidance, platforms, and technologies that are pushing the crews and equipment of the PLAN submarine force in ways they have not been stressed before." "But it still must improve further to be capable of supporting what is expected of the submarine force."

Editor’s note: A version of this story appeared in CNN’s Wonder Theory science newsletter. Analysis of ancient DNA recovered from human remains has illuminated the traits and ancestry of historic individuals — be it a mummified iceman, Chinese emperor or legendary composer. The origins of the empire and its people remained obscure until a landmark April 2022 study found they hailed from the Mongolian steppe. Carolyn Kaster/APNaturalists have spotted the first arrivals in this spring’s historic cicada dual emergence.

Four years ago, I started commuting to my high school — which is an hour away — by train. But that ended when I started high school at The Hudson School, which is 25 miles away from my home in Madison, New Jersey. AdvertisementNow that I'm a high school senior, I look back fondly on my four-year commute. AdvertisementI imagined how much easier it would be if I were a regular high school student who took the bus to school. Still, I'm glad I got to commute 25 miles every day before heading off to collegeLooking back at the past four years, I realize commuting has helped prepare me for the real world — outside high school.

A severely ill 54-year-old woman earlier this month became the second person to receive a kidney transplanted from a genetically modified pig, surgeons at NYU Langone Health in New York announced on Wednesday. The patient, who had both heart failure and kidney failure, was given the organ on April 12, just eight days after receiving a mechanical heart pump. Surgical teams at NYU Langone carried out the two procedures over the course of nine days. The kidney came from a genetically engineered pig provided by United Therapeutics Corporation, a biotech company. The pig carried a gene for producing a sugar called alpha-gal that had been “knocked out,” or blocked.

Despite economic challenges looming large — including prolonged downturns in both the housing and stock market — China’s fascination with luxury watches remains undiminished. Cyril Zingaro/WWGF/KeystoneCertainly at this year’s fair, well-dressed, well-accessorized Chinese customers appeared unfazed by economic uncertainties. After more than 20 years working in the region, he believes China’s economic slowdown is just a temporary phase. “The situation may be slightly (more) challenging for mid-level luxury brands (whose clients’ disposable incomes are potentially more at the whim of market forces). Collectors appreciate the craftsmanship, rarity, and heritage associated with luxury timepieces, which can hold or increase in value over time.

The head of the Federal Aviation Administration on Friday said the agency will increase the required amount of rest time for air traffic controllers in response to concerns over fatigue amid a staffing shortage. "In my first few months at the helm of the FAA, I toured air traffic control facilities around the country — and heard concerns about schedules that do not always allow controllers to get enough rest," FAA Administrator Mike Whitaker said in a statement. A shortfall of air traffic controllers, made worse by a pause in hiring during the Covid-19 pandemic, has led to forced overtime and packed schedules for staff at some facilities. Air traffic controllers in the U.S. are required to retire at age 56. The announcement came alongside an FAA-ordered report on air traffic controller fatigue, which recommended the new rest requirements.

Leslie used her DoorDash side hustle to help pay down her student loan debt. Leslie used her early DoorDash earnings to eliminate her car loan, then began throwing the rest at her remaining student loan balance. "It was really important that I got a lot of my student loan debt taken care of because then I was able to dedicate that back into myself and my health and my mental wellness," she says. Working toward a debt-free futureAlthough Leslie says her student loan debt is at a more manageable level, she plans to continue working part-time as a DoorDash delivery driver for now.

Put simply, the halving is an automatic 50% reduction in the number of bitcoin entering circulation. “Guessing the endgame for Bitcoin after each halving is the ultimate sport,” said Antoni Trenchev, co-founder of crypto lender Nexo, in a statement. Miners are essentially auditors on the bitcoin blockchain, using powerful supercomputers to validate transactions and getting paid for their work in bitcoin. While long-term sentiments on bitcoin are bullish among the crypto faithful, the psychology around an event like the halving is hard to predict and can create volatility that’s extreme even by crypto standards. “It wouldn’t be surprising to see the price of bitcoin increase significantly over the next two years.”

New York CNN —Boeing on Monday scrambled to address safety and quality concerns about its planes ahead of a whistleblower hearing in the Senate on Wednesday. Salehpour is set to be the key witness at a Wednesday hearing of the Senate permanent subcommittee on investigations. That has sparked investigations and allegations that some Boeing employees felt reluctant to raise questions about the safety of the planes they are building or inspecting for fear of retaliation. The average 787 does 600 flights a year, according to Chisholm, and the tests Boeing put the planes through simulated 165,000 flights. Boeing and the Federal Aviation Administration have admitted that some of the planes did have problems with the gaps between parts of the fuselages that were wider than the standards set by Boeing.

An employee works on the tail of a Boeing Co. Dreamliner 787 plane on the production line at the company's final assembly facility in North Charleston, South Carolina. Boeing denied the allegations, calling them "inaccurate" and said it stood by the planes' safety. Salehpour is scheduled to appear along with another whistleblower who worked at Boeing, a former aviation official and an independent safety expert at a Senate hearing on Wednesday about aircraft safety called "Examining Boeing's Broken Safety Culture: Firsthand Accounts." Boeing last week declined to comment on those specific allegations, citing the FAA's ongoing whistleblower investigation, but said, "Retaliation is strictly prohibited at Boeing." The company is scheduled to report quarterly results on April 24, when it will face investor questions about aircraft safety, production rates and FAA oversight.

Diptych, dyad, dialectic: The relationship between the first pair of buildings Philip Johnson designed for his estate in New Canaan, Conn., has taxed the metaphorical imaginations of critics and architectural historians since the structures were completed, just months apart, in 1949. On one side, the Glass House, transparent and entirely self-possessed, a work of modernist daring framed in steel and inspired, as Johnson was only too happy to admit, by the designs of his hero, the German architect Ludwig Mies van der Rohe. On the other, the Brick House, sometimes called the Guest House, hiding behind its inscrutable exterior the bedroom Johnson called his “sex room,” as well as the mechanical equipment serving its more glamorous relative 105 feet away. Point, counterpoint. You could write a book about the Freudian relationship between the two buildings, linked by a tunnel carrying water and power — a connection Johnson called the “umbilical cord.” And in fact somebody has: Adele Tutter, associate clinical professor of psychiatry at Columbia University, whose 2016 study “Dream House: An Intimate Portrait of the Philip Johnson Glass House” observes that the architect, fully exposed “in his transparent house, nevertheless remained ever-connected to a source of warmth and sustenance, hidden behind a forbidding and impenetrable facade, in a house of earthen brick.”

CNN —While Manchester City manager Pep Guardiola was watching his team play Real Madrid in the first leg of the Champions League quarter-finals on Tuesday, his watch was making headlines around the world. Guardiola was wearing an extravagant Richard Mille watch worth £1 million ($1.26 million) on his wrist at Madrid’s Estadio Santiago Bernabéu, according to TNT Sports, which is owned by Warner Bros. The limited-edition timepiece — one of only 50 ever made — is the lightest mechanical watch ever made, according to the designer, weighing only 18.83 grams including the strap. It was originally designed for 22-time Grand Slam tennis champion Rafael Nadal to wear while playing and so every element was carefully engineered to minimize its weight. Guardiola's Manchester City won the Champions League last year.

Wooden turbine towers could make wind power even greener
  + stars: | 2024-04-10 | by ( Arya Jyothi | ) edition.cnn.com   time to read: +6 min
Swedish company Modvion believes it has found a greener alternative — building turbine towers from wood. ModvionAccording to Otto Lundman, co-founder and CEO of Modvion, using wooden towers reduces the lifecycle emissions of a wind turbine by over 25%, and by 90% if you only compare the tower component of the turbine. He adds that if you take into account the carbon dioxide absorbed by trees when they grow, the wooden towers can be considered to store more carbon that they emit. In 2023 the company installed its first commercial two-megawatt unit, a 105-meter-high (345 feet) wooden turbine tower, called Wind of Change, outside Skara, Sweden, for electric utility company Varberg Energi. “But in wind power standards, wood is not really considered for the towers, it’s mostly steel and concrete.
