Mist and microlightning solflare wallet To recreate a scenario that may have produced Earth’s first organic molecules, researchers built upon experiments from 1953 when American chemists Stanley Miller and Harold Urey concocted a gas mixture mimicking the atmosphere of ancient Earth. Miller and Urey combined ammonia (NH3), methane (CH4), hydrogen (H2) and water, enclosed their “atmosphere” inside a glass sphere and jolted it with electricity, producing simple amino acids containing carbon and nitrogen. The Miller-Urey experiment, as it is now known, supported the scientific theory of abiogenesis: that life could emerge from nonliving molecules. For the new study, scientists revisited the 1953 experiments but directed their attention toward electrical activity on a smaller scale, said senior study author Dr. Richard Zare, the Marguerite Blake Wilbur Professor of Natural Science and professor of chemistry at Stanford University in California. Zare and his colleagues looked at electricity exchange between charged water droplets measuring between 1 micron and 20 microns in diameter. (The width of a human hair is 100 microns.) “The big droplets are positively charged. The little droplets are negatively charged,” Zare told CNN. “When droplets that have opposite charges are close together, electrons can jump from the negatively charged droplet to the positively charged droplet.” The researchers mixed ammonia, carbon dioxide, methane and nitrogen in a glass bulb, then sprayed the gases with water mist, using a high-speed camera to capture faint flashes of microlightning in the vapor. When they examined the bulb’s contents, they found organic molecules with carbon-nitrogen bonds. These included the amino acid glycine and uracil, a nucleotide base in RNA. “We discovered no new chemistry; we have actually reproduced all the chemistry that Miller and Urey did in 1953,” Zare said. Nor did the team discover new phys

Americans nearing retirement and recent retirees said they were anxious and frustrated following a second day of market turmoil that hit their 401(k)s after President Donald Trump’s escalation of tariffs. kraken17 As the impending tariffs shook the global economy Friday, people who were planning on their retirement accounts to carry them through their golden years said the economic chaos was hitting too close to home. kra4 Some said they are pausing big-ticket purchases and reconsidering home renovations, while others said they fear their quality of life will be adversely affected by all the turmoil. “I’m just kind of stunned, and with so much money in the market, we just sort of have to hope we have enough time to recover,” said Paula, 68, a former occupational health professional in New Jersey who retired three years ago. Paula, who spoke on the condition of anonymity because she feared retaliation for speaking out against Trump administration policies, said she was worried about what lies ahead. https://kra33at.com “What we’ve been doing is trying to enjoy the time that we have, but you want to be able to make it last,” Paula said Friday. “I have no confidence here.” Trump fulfilled his campaign promise this week to unleash sweeping tariffs, including on the United States’ largest trading partners, in a move that has sparked fears of a global trade war. The decision sent the stock market spinning. On Friday afternoon, the broad-based S&P 500 closed down 6%, the tech-heavy Nasdaq dropped 5.8%, and the Dow Jones Industrial Average fell more than 2,200 points, or about 5.5%.
