Newly discovered Cambrian fossils indicate that bryozoans, colonial marine invertebrates, were already present and diversified during the Cambrian explosion. This overturns the long-held view that the phylum was absent from early Cambrian ecosystems.
8:00 PMNatureNASA has assigned a crew to Artemis III, the mission planned to return astronauts to the Moon in 2027. The announcement lands amid uncertainty about whether Blue Origin's New Glenn rocket explosion could disrupt key logistics tied to the program.
2:35 PMAl JazeeraNASA has named the next Artemis crew, but the assignment is for a mission that will not land on the Moon or approach the lunar surface. The crew selection underscores that near-term Artemis flights remain focused on testing and operations rather than a return to walking on the Moon.

8:00 PMNatureSummary
Newly discovered Cambrian fossils indicate that bryozoans, colonial marine invertebrates, were already present and diversified during the Cambrian explosion. This overturns the long-held view that the phylum was absent from early Cambrian ecosystems.
Why it matters
It rewrites a key branch of the animal tree and tightens the timeline for how complex marine ecosystems formed early in Earth’s history.
Summary
NASA has assigned a crew to Artemis III, the mission planned to return astronauts to the Moon in 2027. The announcement lands amid uncertainty about whether Blue Origin's New Glenn rocket explosion could disrupt key logistics tied to the program.
Why it matters
Crew announcements signal commitment, but the mission will be decided by launch reliability and supply chain resilience, not personnel.
Summary
NASA has named the next Artemis crew, but the assignment is for a mission that will not land on the Moon or approach the lunar surface. The crew selection underscores that near-term Artemis flights remain focused on testing and operations rather than a return to walking on the Moon.
Why it matters
Artemis progress will be judged by whether test flights translate into landing capability on a credible timeline.
Summary
The Nature Index 2026 Research Leaders rankings show Japan and South Korea improving their position and research output relative to many Western counterparts, even as China continues to dominate the region’s growth in high-quality publications. The data points to a more competitive East Asian research bloc with strengths concentrated in selected institutions and fields.
Why it matters
Research leadership is moving toward East Asia, reshaping who sets agendas, attracts top scientists, and captures downstream economic and security advantages.

Researchers propose that the Amaterasu particle, an ultra high energy cosmic ray detected on Earth, may be an ultraheavy atomic nucleus rather than a proton. Ultraheavy nuclei could better preserve energy over long distances, making their arrival at Earth more plausible and narrowing the range of possible source events.

Why it matters
Pinning down what these particles are is the quickest path to identifying the astrophysical engines that can out-accelerate every known accelerator in nature.
