That’s not to say the work is finished. “It’s much less real than the real world, even the best simulator,” said Daniel Yamins, a computer scientist at Stanford University. With colleagues at MIT and IBM, Yamins co-developed ThreeDWorld, which puts a strong focus on mimicking real-life physics in virtual worlds — things like how liquids… Continue reading AI Makes Strides in Virtual Worlds More Like Our Own

Explore With their daughter in the hospital suffering from kidney failure, Jonathan Bate and his wife Paula Byrne waited. “In that darkest moment, when she was struggling to survive, it was very hard to think of anything other than the prospect of losing her,” Bate says today.

Cook often watched as the insects responded… Continue reading How Are the Bees?

In 2020 experts at the U.S. Biomedical Advanced Research and Development Authority (BARDA) and other public health agencies watched a presentation that many thought was impractical at the time. Several companies proposed to regularly sample wastewater from sewers and treatment plants and run tests to detect SARS-CoV-2—the virus that causes COVID-19. People excrete the virus… Continue reading Wastewater Monitoring Offers Powerful Tool for Tracking COVID and Other Diseases

Russia’s unprovoked invasion of Ukraine has unleashed an outpouring of condemnation from scientists and research organizations worldwide. Some organizations in Western nations have moved to quickly sever links with Russia—cutting off funding and resources and ending collaborations with Russian scientists. And from Mauritius to Latvia, national science academies and groups of researchers have issued statements… Continue reading Global Science Community Condemns Russian Invasion of Ukraine

Balance-scale puzzles abound in recreational mathematics. The essential element is the humble two-pan balance scale — a staple of commerce over the millennia that’s still found in bustling rural bazaars in the developing world. The simplest versions consist of a metal beam from which hang two pans at equal distances from the central support or… Continue reading Puzzles on Weighing Truth With a Balance Scale

Explore After experimenting on a hen, his dog, his goldfish, and himself, dentist William Morton was ready. On Oct. 16, 1846, he hurried to the Massachusetts General Hospital surgical theater for what would be the first successful public test of a general anesthetic. His concoction of sulfuric ether and oil from an orange (just for… Continue reading Under Anesthesia, Where Do Our Minds Go?

Explore What’s enchanting about our oceans is how unexplored they still are, teeming with unknown species. Scientists add, on average, around 2,000 new entries to the World Register of Marine Species every year. It can be profoundly moving to fathom the scale of sea life and the strange forms it can take. The sobering reality… Continue reading Automatic for the Oceans

In the late 19th century, Florence Nightingale revolutionized hospital design in what became known as Nightingale wards. The signature innovation of these wards was large windows that allowed cross-ventilation and abundant natural light. Nightingale believed that the light and air quality in a hospital’s environment play an important role in speeding patient recovery. In the… Continue reading What Florence Nightingale Can Teach Us about Architecture and Health
