Astronomers found two white dwarfs with no companions that emit X-rays anyway. It took two to define a new class.

220 PeV. That number is three orders of magnitude beyond what any Earth-based accelerator can produce. Something in the Mediterranean Sea caught it. Now physicists think they know what it was.

On a zero-G parabola, a 5W laser pushed a graphene aerogel 50mm in 30ms. Back on Earth, the same laser barely moved it. Gravity is the whole problem, and microgravity is the whole point.

Less than 2% of Earth came from beyond Jupiter. That undercuts the leading theory for how our oceans arrived. The researchers who ran the numbers cannot yet explain where the water actually came from.

NASA's $20B lunar base will run on OT systems that don't yet have mandatory cybersecurity rules. GAO found 16 open gaps across the agency's portfolio. NASA's crisis model for reform won't work here — OT intrusions produce no single dramatic failure.

Asteroids are compromised. Billions of years of impacts and solar radiation have baked and battered every one we've sampled. Comets haven't.

Nvidia has a $1 trillion backlog and a CPO roadmap for 2028. The chip that makes it possible is yielding 60-65% — meaning 35-40% of every wafer is scrap. The power wall is real. The fix is real. The manufacturing is not proven yet.

The crosstalk engineers spend billions suppressing? Kandou treats it as signal energy — and convinced SoftBank and Cadence to bet $225M on the idea.

Artemis II astronauts observed four to five meteor impacts on the moon far side in real time — data that landing site planners for Artemis III will actually use, not just a presidential call.

The plant runs at 30% capacity. That is not the problem. The problem is the helium stranded near the Strait of Hormuz, the Qatar force majeure, and the war that is making the chip industry desperate to localize supply chains it cannot actually control.

They traveled farther from Earth than any human in history. While there, they paused to name craters after loved ones. Science and sentiment aren't opposites.
