Singapore lowers 2030 emissions forecast, to boost hydrogen


Singapore cut its forecast for its carbon dioxide emissions in 2030 and will achieve a peak in emissions earlier than that as the city-state strives to achieve net zero by 2050, Deputy Prime Minister Lawrence Wong said on Tuesday.
Singapore plans to reduce its carbon emissions target for 2030 to 60 million tonnes of carbon dioxide (CO2), Wong said at the Singapore International Energy Week conference.

The country previously aimed for emissions to peak at 65 million tonnes of CO2 equivalent in 2030.

Longest nonstop bird flight: A new world record


A five-month-old bird has set a new world record for longest nonstop bird flight. The bar-tailed godwit – aka Limosa lapponica – traveled from Alaska to Tasmania nonstop for 11 days, a journey of 8,425 miles (13,560 km). The godwit took off from Alaska on October 13, 2022, and reached Ansons Bay in Tasmania, just south of Melbourne, Australia, on October 24. Since the young bird was tagged, it allowed scientists to accurately track its flight.

US embassies may have accidentally improved air quality


In 2008, the United States embassy in Beijing installed an air-quality monitor and started tweeting out its findings every hour. Since then, these monitors have popped up in more than 50 embassies in countries and cities around the globe.

Something unexpected happened in each of the cities in which the monitors appeared. Researchers found that, overall, air quality improved in the cities where embassies were tweeting out air-quality data. “We were surprised,” Akshaya Jha, assistant professor of economics and public policy at Carnegie Mellon University and one of the paper’s authors, told Ars.

They made a material that doesn't exist on Earth. That's only the start of the story.


It sounds like the plot of a science fiction movie: humans are destroying the Earth, gouging huge scars in its crust, and polluting the air and the ground as they mine and refine a key element essential for technological advance. One day, scientists examining an alien meteorite discover a unique metal that negates the need for all that excavation and pollution. Best of all, the metal can be replicated, in a laboratory, using base materials.

Can AirPods do the job of $10,000 hearing aids?


Hearing loss is thought to affect as much as 15% of American adults, but hearing aids aren’t always easy to come by. A team of scientists exploring low-cost alternatives has turned to Apple’s AirPods as a potential solution, assessing them alongside conventional hearing aids to find they stack up surprisingly well.

Hybrid ultracap battery promises 72-second city EV charging


An electric car that can charge in as little time as it takes to pump a gas vehicle has long been the dream of existing and would-be EV drivers. But what if it could charge even more quickly? The average gas fill-up takes two minutes, according to the American Petroleum Institute, with other estimates coming in higher. A new electric energy storage technology being developed by Swiss tech startup Morand could offer electric city car charging times in slightly more than half that two-minute time. A cross between traditional batteries and ultracapacitors, the company's eTechnology units offer potential game-changing charging rates, coupled with the possibility of much longer lifespans than lithium-ion batteries.
