Companies large and small are working on cleaning up the skies with electric airplanes, bringing back supersonic travel, and even flirting with the edge of space to transport passengers across the world.
For the first time, scientists have created a silicon chip that can accelerate electrons - albeit at a fraction of the velocity of the most massive accelerators - using an infrared laser to deliver, in less than a hair.
A new study shows that heat energy can leap across a few hundred nanometers of a complete vacuum, thanks to a quantum mechanical phenomenon called the Casimir interaction. It could have profound implications for the design of computer chips.
The Pacific nation of Palau has become the first country to ban sun cream that is harmful to corals and sea life. From now sun cream that includes common ingredients, including oxybenzone, is not allowed to be worn or sold in the country.
Superblocks is a radical plan to reclaim the streets from the noise and pollution of traffic, one that could save hundreds of lives that might otherwise be lost because of heavily polluted air. It also hopes to act as a blueprint for other cities.
Apocalyptic scenes are playing out across Australia as bushfires have burned millions of acres and ravaged more than 1,000 homes in New South Wales alone. The new normal is not only more lethal, it's also harder to predict.
Kanzas is the first major one in the U.S. to offer no-cost public transportation. Most of the world’s fare-free transit systems are in Europe, including a number of towns in Poland, France and Estonia's capital Tallinn.
They’re cloyingly sweet, nutritionally empty—and, increasingly, subject to taxation. More than 35 countries and seven cities in the US — now impose a tax on soda and other sugar-sweetened beverages, and several more places are considering it.
Five studies found that a 10µg/m3 increase in the average level of fine particulate matter (PM2.5) air pollution people were exposed to over long periods was associated with an approximately 10 percent increase in their odds of depression.
Betelgeuse in constellation of Orion is looking markedly faint, the faintest it has been for the 21st century. Betelgeuse is a nearby supernova candidate. Its transformation into Type II supernova could occur 100,000 years from now… or tonight.
The recently discovered increase in emissions of trichlorofluoromethane (CFC-11) may delay the recovery of the Antarctic ozone hole by over a decade if it continues, suggests a modelling study.
The data adds to signs that climate change is fostering a sense of so-called "flying shame" that’s causing some people to avoid one of the most polluting forms of travel. Significantly more people are taking the train on trips within Europe that are less four hours.
Astronomers spotted a magnetic explosion on the surface of the sun unlike anything they've ever seen before. Although it was initially theorized about 15 years ago, this was their first direct observation of it thanks to NASA's Solar Dynamics Observatory.
INPE’s satellite-based short-term deforestation detection system has recorded 8,683 square kilometers of forest clearing since January 1, the highest on record since the agency started releasing monthly data in 2007. 2019’s figure is 79% higher than a year ago.
Waters off the California coast are acidifying twice as fast as the global average, scientists found, threatening major fisheries and sounding the alarm that the ocean can absorb only so much more of the world’s carbon emissions.
