The Apple Watch is full of sensors whether you pick up a new Apple Watch Ultra 2 or are still rocking an older Apple Watch Series 7, but Apple is always likely to try and add more. There have long been rumors of the addition of things like a blood pressure sensor and more, and Apple's recent legal issues notwithstanding, the Apple Watch's blood oxygen sensor can be super useful alongside the heart rate sensor and ECG.While the Apple Watch can already measure the wearer's temperature, that particular sensor is only…

According to their report, titled "Dynamic Polycentrism," in order to determine the health of a digital space, experts must first determine its level of pluralism. …

The citizen-sponsored ballot initiative that aims to force Los Angeles to add hundreds of miles of bike and bus lanes — to make streets safer for pedestrians and bicyclists — was leading by a wide margin in early returns.If passed, it would require 238 miles of protected bike lanes and add hundreds more unprotected lanes, transforming some of the region’s most storied boulevards. Ventura Boulevard in the San Fernando Valley and Soto Street on the Eastside, among dozens of others, would get new bike lanes. The measure…

Zingy one-liners and star power helped the film coast right into the hearts of its teen fanbase. This…

Acting on a tiny particle levitating in a magnetic trap, physicists have just measured the smallest gravitational pull ever recorded.The particle weighed just 0.43 grams. And the strength of the gravitational force at play was on the scale of attonewtons (10-18 newtons). That's small enough to be right on the verge of the quantum realm, teasing the possibility of finally figuring out how classical physics and quantum mechanics interact."For a century, scientists have tried and failed to understand how gravity and quantum…

Despite keeping us grounded and warping light that travels through space, gravity is actually quite a weak force. The smaller the mass, the less gravity appears to have any pull, until at quantum scales it appears to have no force at all.Dave Bautista Opens Up About His Relationship With Denis VilleneuveNow, physicists in England and Europe have measured a tiny—but apparent—gravitational pull on a minuscule mass, making it the smallest mass to yet show the signs of gravity, a force that has perplexed physicists for…

They says it's unfair that when children "fail" these tests it can mean they receive a worse secondary education than their more successful peers—sentencing them to a lifetime of disadvantage. Some object to IQ tests for quite…

The Food and Drug Administration on Wednesday issued a safety communication warning people to stay way from smartwatches and smart rings that claim to measure blood sugar levels without pricking the skin. “The FDA has not authorized, cleared, or approved any smartwatch or smart ring that is intended to measure or estimate blood glucose values on its own,” the agency wrote in the communication, and asked consumers, patients, and caregivers to stay away from such devices.Non invasive blood sugar monitoring isn’t currently…
