Sitting at his home computer on the evening of 22 April, Tom Murphy, an astrophysicist at the University of California, San Diego, logged into an observation session 1200 kilometers away, at Apache Point Observatory. From a pine-dotted ridge above the White Sands Missile Range, Russet McMillan, the on-site specialist, aimed the New Mexico observatory's telescope at a small patch of dust near the edge of the moon's face. Then, at Murphy's go-ahead, she fired a stream of laser pulses into the night sky.

Acer, the world’s fifth largest PC brand, wants to take the growing AR/VR market by the horns with its SpatialLabs glasses-free stereoscopic 3D displays.

First teased in 2021 in a variant of Acer’s ConceptD 7 laptop, the technology expands this summer in a pair of portable monitors, the SpatialLabs View and View Pro, and select Acer Predator gaming laptops. The launch is paired with AI-powered software for converting existing 2D content into stereoscopic 3D.

DARPA Wants a Better, Badder Caspian Sea Monster

Arguably, the primary job of any military organization is moving enormous amounts of stuff from one place to another as quickly and efficiently as possible. Some of that stuff is weaponry, but the vast majority are things that support that weaponry—fuel, spare parts, personnel, and so on. At the moment, the U.S. military has two options when it comes to transporting large amounts of payload. Option one is boats (a sealift), which are efficient, but also slow and require ports. Option two is planes (an airlift), which are faster by a couple of orders of magnitude, but also expensive and require runways.

To solve this, the Defense Advanced Research Projects Agency (DARPA) wants to combine traditional sealift and airlift with the Liberty Lifter program, which aims to “design, build, and flight test an affordable, innovative, and disruptive seaplane” that “enables efficient theater-range transport of large payloads at speeds far exceeding existing sea lift platforms.”
