- 1Rocket Lab drops 11% as Neutron rocket slips to 2027▼Rocket Lab Tumbles 11% as Neutron's First Flight Moves to 2027; SpaceX and AST SpaceMobile Pull Back
Rocket Lab shares fell roughly 11% after the company pushed the maiden flight of its Neutron rocket to 2027. The delay weighed on the broader space sector, with SpaceX-linked sentiment and AST SpaceMobile shares also pulling back. Investors had been counting on Neutron, a medium-lift reusable rocket, as the company's next major growth driver beyond its Electron launcher.
- 2Gabon's natural nuclear reactor ran two billion years ago●Nature beat us to nuclear power by ~1.7 billion years. In what's now Gabon, Africa, natural uranium deposits went critic
Scientists are highlighting the Oklo uranium deposits in Gabon, where around 1.7 billion years ago natural nuclear fission reactions occurred without any human involvement. Groundwater seeping through uranium-rich rock slowed neutrons enough to sustain fission, then boiled off and paused the reaction in self-regulating cycles. The phenomenon is being shared as a striking example of nature achieving nuclear power long before humans.
- 3Rocket Lab Retail Sentiment Hits Low After Neutron Delay●Rocket Lab Retail Mood Hits All-Time Low After Neutron Delay — Can Takeover Target Iridium’s Earnings Turn The Tide?
Retail investor sentiment toward Rocket Lab has fallen to an all-time low following the company's latest delay of its Neutron rocket program. Attention now turns to Iridium, the satellite communications company widely viewed as a potential takeover target, whose upcoming earnings report is seen as a possible catalyst that could shift the mood around Rocket Lab's stock and its expansion strategy.

Licube, a new startup spun out of membrane-based electrolyzer research at Hirosaki University, is developing technology to purify lithium-6. The isotope is prized by fusion developers because it breeds tritium efficiently when struck by neutrons, and fusion reactors face a significant tritium supply shortage. Observers see the venture as addressing a key bottleneck for future fusion energy.

Astronomy enthusiasts are sharing a striking fact about neutron stars: a single teaspoon of their matter would weigh around a billion tons, roughly the mass of a mountain. The posts explain that when a massive star dies, its core collapses so violently that protons and electrons merge into neutrons, packing more than the Sun's mass into a sphere only about 20 kilometres wide.
- 6Jonathan Haidt Calls AI a 'Neutron Bomb for Education'▼Jonathan Haidt: AI Is the 'Neutron Bomb for Education' [video]
Social psychologist Jonathan Haidt warns that artificial intelligence is a 'neutron bomb for education' — a technology that could leave school buildings standing while devastating learning inside them. His remarks argue that AI tools risk hollowing out students' writing, critical thinking and independent work as schools rush to adopt them. The warning is fuelling debate among educators and technologists over whether AI belongs in classrooms at all.

Social psychologist Jonathan Haidt argues that artificial intelligence is poised to devastate education, likening its impact to a 'neutron bomb' that leaves institutions standing but hollows out learning itself. Writing in The Atlantic, he warns that AI tools risk stripping students of the struggle essential to genuine understanding, echoing his earlier concerns about smartphones and social media's effects on young people.

Rocket Lab is being positioned as an emerging challenger to SpaceX's dominance in the space industry. The company, known for its Electron small-launch vehicle and developing Neutron rocket, is expanding its capabilities in launch services and space systems as it works to close the gap with Elon Musk's market leader.
- 9Rocket Lab Stock Slips Despite Electron Approaching 100th Launch●RKLB Stock Slips Overnight Despite Electron’s Push Toward 100th Launch — Retail Still Frets Over Neutron Delays
Rocket Lab shares dipped in overnight trading even as the company's Electron rocket edges toward its 100th launch, a milestone for the small-launch pioneer. Retail investors remain focused less on the streak and more on repeated delays to Neutron, the company's larger reusable rocket seen as key to future growth and competing with SpaceX.

CERN Courier examines the strength of the strong interaction, the fundamental force that binds quarks into protons and neutrons and holds atomic nuclei together. The piece explores how physicists quantify this force, whose coupling constant runs with energy, and why pinning down its exact strength remains a key challenge in particle physics and precision tests of the Standard Model.

Rocket Lab has pushed the first flight of its Neutron rocket to 2027, sending shares lower. The delay comes shortly after the company announced its largest commercial deal yet for the smaller Electron rocket, lifting its launch backlog above 100 missions. Investors are weighing the setback against strong demand for its established launch business.

A science post is explaining accretion, the process by which matter falls toward massive compact objects such as black holes and neutron stars. Although these objects are extremely massive, their physical dimensions are small, so infalling material often forms a swirling disk around the black hole before crossing the event horizon. The explanation highlights how accretion powers some of the brightest phenomena observed in the universe, making it a familiar concept in the study of compact astrophysical systems.

Astronomers report that light from a magnetar — a neutron star with an extreme magnetic field — shows signs that empty space itself may be altering how the light travels, a phenomenon known as vacuum birefringence. The finding, if confirmed, would be the first direct evidence of this quantum electrodynamics prediction, with observers discussing what it could mean for physics.
