A few blobs of lab-grown brain tissue have demonstrated a striking proof of concept: living neural circuits can be nudged toward solving a classic control problem through carefully structured feedback. In a closed-loop system that delivered electrical feedback based on performance, cortical organoids could steadily improve their control of a classic engineering benchmark: balancing an
The recent image of the Falcon 9 rocket’s plume, captured during NASA’s Crew-12 mission launch, has taken the world by storm. The stunning nebula-like pattern, a byproduct of the rocket’s intense exhaust, offers a glimpse into the power and beauty of space exploration. As rockets break through Earth’s atmosphere, they leave behind spectacular visuals, showcasing

And not just any. I mean a good fossil. Not some bugs that got caught in mud or some ground sloth’s tooth.
Venting when angry seems sensible. Conventional wisdom suggests that expressing anger can help us quell it, like releasing steam from a pressure cooker. But this common metaphor is misleading, according to a 2024 meta-analytic review. Researchers at Ohio State University analyzed 154 studies on anger and found little evidence that venting helps. In some cases,
NASA and contractor engineers pumped more than 750,000 gallons of supercold propellants into the agency’s huge Space Launch System rocket Thursday without any signs of hydrogen leaks in a major step toward launching four astronauts on a flight around the moon as early as March 6. The practice countdown began Tuesday night, kicking off a carefully choreographed
The first of two 2026 lunar eclipses will occur on March 3. The total eclipse will cast a red tint as the moon falls into Earth’s shadow. Utah observers will be in prime viewing area, weather permitting. While only a handful of Antarctic scientists were in the right spot for prime viewing of a stunning

Using NASA/ESA/CSA James Webb Space Telescope’s NIRSpec instrument, the team observed Uranus for nearly a full rotation, detecting
CAPE CANAVERAL, Fla. (AP) — NASA took another crack at fueling its giant moon rocket Thursday after leaks halted the initial dress rehearsal and delayed the first lunar trip by astronauts in more than half a century. For the second time this month, launch teams pumped more than 700,000 gallons (2.6 million liters) of supercold
