In March 2021, Berkeley, Calif., became the first city in the world to ban the display of sugary beverages and snacks in store checkout lanes, where candy, chocolate and soda are commonly placed to encourage impulse buying while shoppers are in line.
It's the season for babies in the snake world, and Project RattleCam is capturing magical moments.
The seemingly trivial ability to hear a regular pulse in music is a remarkable—and perhaps distinctively human—feature of the brain. In a wide-ranging critical review, Gábor Háden of the HUN-REN Research Centre for Natural Sciences and Henkjan Honing of the University of Amsterdam evaluate more than two decades of research into how this capacity develops and has evolved. Their paper was published this week in the Annals of the New York Academy of Sciences.
Imagine telling your phone that you want a quiet boutique hotel near a city center, below a certain price, with a decent breakfast and late checkout. A few seconds later, an AI assistant compares the options, explains why each one fits and helps complete the booking. This is no longer hypothetical.
Fluorinated waste, like that found in firefighting aqueous film-forming foam, can act as a significant environmental pollutant. Recently, James Tour's lab at Rice University developed a method to capture fluoride from these waste streams and recycle it into a useful reagent, silver fluoride, that could be used in other manufacturing processes. This process is published in Nature Chemical Engineering.
The summer before starting university can bring multiple worries for students: worrying about obtaining a place in a desired program, navigating the clearing process to confirm a place, securing housing, sorting out financial aid, preparing for academic study and even finding the right school supplies.
New research has highlighted the important role public libraries play in supporting communities, helping people build connections, access support and improve their well-being through everyday interactions.
For the first time, important features of the Antarctic coastal zone have been mapped at high resolution around the continent by training an artificial intelligence tool to accurately recognize grounded icebergs in satellite radar images.
Scientists were shocked when they received the first images of Martian gullies. They were even more shocked as those gullies appeared to change over time. Their similarities to gullies seen on Earth were uncanny, but all of Earth's gullies are formed by water runoff, and Mars is too cold and has too sparse an atmosphere to have liquid water on its surface. Whatever has been causing those changing gullies couldn't have been water, so what was it? A new paper from Apolline Leclef of the Institut d'Astrophysique Spatiale at Université Paris-Saclay and her colleagues, available on the arXiv preprint server, shows how they are likely caused by CO2 frost turning into a fluid.
Northern India experiences some of the world's worst winter air pollution, with dangerous episodes often prompting emergency control efforts. In major cities like Delhi, the Air Quality Index has reached levels above 999—over 30 times the World Health Organization's safety limit.
