There has not been enough progress in our understanding of the basic mechanisms underlying psychosis. Studying psychotic disorders in animal models is difficult because the diagnosis relies on self-reported symptoms that can only be assessed in humans. Schmack et al. developed a paradigm to probe and rigorously measure experimentally controlled hallucinations in rodents (see the Perspective by Matamales). Using dopamine-sensor measurements and circuit and pharmacological manipulations, they demonstrated a brain circuit link between excessive dopamine and hallucination-like experience. This could potentially be useful as a translational model of common psychotic symptoms described in various psychiatric disorders. It may also help in the development of new therapeutic approaches based on anatomically selective modulation of dopamine function.

The fifth Space Based Infrared System satellite was delivered to Florida ahead of an anticipated May launch.

The three-year arrangement will allow allies to begin testing M-Code-ready equipment.

Based on the recommendations of weather forecasters, Operation Overlord’s June 5 D-Day was postponed due to a weather front. However, the operation was launched one day later when analysis projected a short period of acceptable weather. Germany’s forecasters missed this break, and the results were cataclysmic for German forces.

The Korean and Vietnam conflicts highlighted a growing need for “weather superiority” as enemy forces learned to take advantage of periods of bad weather that limited the effectiveness of U.S. air forces. Even in Desert Storm, the first item in planning the daily air operations began with a weather forecast.

Today, superior knowledge of environmental conditions is a force multiplier for all the services in an era where concepts like Joint All-Domain Command and Control are accelerating the speed and precision at which war is conducted. The outcome of future conflict will depend on rapid, accurate and more fully informed decisions. If a commander lacks an assured source of high-fidelity intelligence about the environment, then tools, tactics and timing cannot be aligned to achieve desired outcomes.

This means 6 years after TAE began to reach “long enough,” Norman has finally reached “hot enough” frequently enough that it can begin to scale up for commercial power plants. And this is why the company says it feels it can build that kind of power plant by the end of the decade in 2030.

Nuclear fusion has long felt like decades away. Today, the timeline accelerates.

A patchwork of genomic differences in the placenta may explain the organ’s “live fast, die young” strategy and its connections to cancer.

NGAD is the Navy’s effort to replace the Super Hornet. Note: It’s a completely separate program from the Air Force’s own NGAD—which recently designed, tested, and flew a secret new fighter jet—and will produce a completely separate plane. The two aircraft will almost certainly be quite different, with the Air Force’s jet more optimized for air superiority. It’s likely the two fighters, developed roughly within the same time period, will share much of the same technology.

The U.S. Navy elaborated on its plans to replace the F/A-18E/F Super Hornet, saying the service’s next strike fighter will “most likely be manned.” The jet will probably fly alongside robotic allies, and remotely crewed aircraft could eventually account for six out of 10 planes on a carrier flight deck.

“As we look at it right now, the Next-Gen Air Dominance [NGAD] is a family of systems, which has as its centerpiece the F/A-XX—which may or may not be manned—platform. It’s the fixed-wing portion of the Next-Gen Air Dominance family of systems,” said Rear Adm. Gregory Harris, the head of the Chief of Naval Operations’ air warfare directorate, during a Navy League event.

The rotor blades on the Ingenuity helicopter were unlocked and the Perseverance rover’s arm was run through some checks in imagery acquired by NASA from Mars on April 8, 2021. Also, Perseverance captured a selfie with the Ingenuity helicopter in April 6 imagery. Full Story: https://www.space.com/mars-helicopter-ingenuity-unlocks-rotor-blades.
