Countrywide natural experiment links built environment to physical activity

Study design We conducted a countrywide, prospective, longitudinal physical activity study of US residents that evaluated their physical activity levels within the context of the walkability of their built environments before and after relocation (‘participants’). We leveraged the naturally occurring physical activity data that was captured by a health app on participants’ phones to compare each person’s physical activity levels before and after they relocated to a different area within the USA

The flash projects the image on the slide through the lens and onto the object. This action is triggered by a built-in sensor that recognises flashes from nearby cameras. That way, the projection can automatically be synchronised with the moment of exposure of any nearby camera using a flash. The Image Fulgurator is housed in a regular single reflex camera case since most of the camera’s elements were re-used for the construction of the Image Fulgurator.

Picking a Spot for NASA’s Lunar Nuclear Reactor Is Trickier Than It Sounds

gizmodo.com Clive Neal 2025-11-18 18:36:22

In a bold, strategic move for the U.S., acting NASA Administrator Sean Duffy announced plans on Aug. 5, 2025, to build a nuclear fission reactor for deployment on the lunar surface in 2030. Doing so would allow the United States to gain a foothold on the Moon by the time China plans to land the first taikonaut, what China calls its astronauts, there by 2030. Apart from the geopolitical importance, there are other reasons why this move is critically important. A source of nuclear energy will be

Can-Am's first electric ATV can haul more than its gas models

engadget.com Unknown 2025-11-19 09:00:21

Can-Am, part of the motorsports group BRP that recently introduced electric snowmobiles, has just launched its first electric all-terrain vehicle (ATV). The Outlander Electric is designed to be "whisper quiet" for chores like herding or hunting, but it can actually tow more than its gas-powered counterparts thanks to the high level of torque. Powered by BRP's modular Rotax E-Power drivetrain (also used in the company's electric snowmobiles and motorbikes), the Outlander Electric makes up to 47

The circular economy could make demolition a thing of the past

Most of us are already quite comfortable recycling our household waste.

Formula 1, often a laboratory for innovation, offers us a real-world example of this in the form of the Red Bull team’s “pit box”, known as the F1Holzhaus – literally, “the wooden house”. It made

The Plan to Turn the Caribbean’s Glut of Sargassum Into Biofuel

wired.com Edith González Cruz 2025-11-19 17:00:00

Esteban Amaro, director of the Quintana Roo Sargassum Monitoring Network, agrees that fuel is the best product to focus on. Processing the seaweed into other consumer products is possible, but inadvisable given that the health risks of doing so have not yet been sufficiently studied. “I believe that sargassum’s purpose is to produce energy, because when it decomposes, it releases many heavy metals such as arsenic, lead, and cadmium,” Amaro says. “Therefore it is better to produce biofuels or bi

What Is the Electric Constant and Why Should You Care?

wired.com Rhett Allain 2025-11-19 09:00:00

It's fun to think about the fundamental physical constants. These are special values used in our models of the physical universe. They include things like the speed of light, the gravitational constant, and Planck’s constant, and they’re “fundamental” in the sense that we can't derive them theoretically, we can only measure them. We use these in solving physics problems all the time, so it’s easy to take them for granted. But why are there such numbers in nature, and why do they just happen to
