Project PLATEAU, led by Japan's Ministry of Land, Infrastructure, Transport and Tourism, aims to develop and expand access to 3D models representing the diversity of cities across the country, enhancing urban resilience and addressing local challenges.
We created Earth in Action to provide a lens into what's happening on our planet, as it happens. Whether it's something typical, like the current air temperature, or an extreme event like a major dust storm, we wanted to provide an opportunity for people to see them.
Along coastlines, where tides are typically magnified, they profoundly affect navigation, commerce, coastal flooding, water properties and sediment transport. Tides impact the flooding of rivers and, thus, influence the extent of their floodplain, which has cascading effects on biogeochemical and ecological processes.
The new Immersive Navigation mode introduces a detailed 3D map that includes buildings, overpasses, crosswalks, traffic lanes, traffic lights, and stop signs. Google bills this new mode as being the most significant update in over a decade to the app's driving experience. According to the American IT giant, the changes should help drivers stay focused and informed on the road, with Maps giving fresh, real-world information and natural directions.
Signals from Global Navigation Satellite Systems are quite vulnerable. They are exceptionally weak, meaning that any radio noise near their frequency, accidental or malicious, can interfere with reception. I am confident that there are people in every government who understand the problem. The challenge is getting leadership to both understand and act to reduce the risk.
On February 28, ships navigating the Strait of Hormuz started appearing on tracking screens in places they couldn't possibly be. They appeared to be sitting on airport runways, parked on Iranian land, and clustered at nuclear power plants. More than 1,100 commercial vessels had their navigation systems scrambled in a single day following US-Israeli airstrikes on Iran, bringing a waterway that handles a fifth of the world's oil exports to a halt.
To capture the biological impact of this extreme environment, I used a comprehensive suite of sensors and biomarker analyses. I wore a wireless electroencephalograph (EEG) system to monitor brain activity, sleep stages and neural signatures of stress and adaptation; the Oura Ring to continuously track sleep patterns, heart-rate variability and circadian-rhythm shifts; and the glucose monitor to follow metabolic responses in real time.
The service is the result of a UK-first partnership with SpaceX, using Starlink's low-Earth orbit satellites to deliver connectivity direct to mobile devices using O2's licensed mobile spectrum transmitted from space. The switch-on also follows recent approval by UK regulator Ofcom of the UK's first licence for satellite-to-smartphone services.
The other day we were scrolling through r/meshtastic and someone asks: "Why does my device show 10+ satellites in view while my buddy's barely sees 8?" Good question. Really good question, actually. And it's about to take us down a rabbit hole that involves atomic clocks, Cold War competition, European independence, and why your Meshtastic node cares about all of this.
By the end of the year, Northwood, based in El Segundo, California, had shown the ability to build eight of these Portal arrays a month. And in January the company had deployed operational Portal antennas across two continents. These deployments, which comprise an area of 8 to 15 meters, have the equivalent capability of a 7-meter parabolic dish, said Griffin Cleverly, co-founder and chief technical officer of Northwood.
Now say you want to run some modest AI stuff. That's a bigger job, so let's scale up our cubical computer with edges twice as long as before. That would make the volume eight times larger (2 3), so we could have eight times as many processors, and we need eight times as much power input-2,400 watts. However, the surface area is only four times (2 2) larger, so the radiative power would be about 4,000 watts.
