Longer breastfeeding duration is associated with improved cognitive scores at ages 5 through 14, even after controlling for socioeconomic position and maternal cognitive ability, according to a study published this week in PLoS ONE by Reneé Pereyra-Elías, Maria Quigley, and Claire Carson of the University of Oxford, U.K. Previous studies have found an association between breastfeeding and standardized intelligence test scores.

Low-cost gel film plucks drinking water from desert air

More than one-third of the world's population lives in drylands that experience significant water shortages. Scientists and engineers at the University of Texas at Austin have developed a solution that could help people in these areas access clean drinking water. The team developed a low-cost gel film made of abundant materials that can pull water from the air in even the driest climates. The materials that facilitate this reaction cost a mere $2 per kilogram,...

Webb telescope team prepares to solve space mysteries

As NASA's James Webb Space Telescope moves through the final phases of commissioning its science instruments, we have begun working on technical operations of the observatory, writes Thaddeus Cesari of NASA's Goddard Space Flight Center. While the telescope moves through space, it will constantly find distant stars and galaxies and point at them with extreme precision to acquire images and spectra. We also plan to observe planets and their satellites, asteroids, and comets in our solar system, which move across...

Solar Orbiter delivers spectacular images of the Sun

Powerful flares, breathtaking views across the solar poles, and a curious solar "hedgehog" are among the haul of spectacular images, movies, and data returned by Solar Orbiter from its first close approach to the Sun. Although the analysis of the new dataset has only just started, it is clear that the ESA-led mission is providing the most extraordinary insights into the sun's magnetic behaviour and the way this shapes space weather. Solar Orbiter's closest approach...

UN says Ukraine invasion could help cause lengthy global food crisis

Russia's invasion of Ukraine could soon cause a global food crisis that may last for years, the UN has warned. UN Secretary-General Antonio Guterres said the war has worsened food insecurity in poorer nations due to rising prices, the BBC reports.
