The article is an author correction to research reporting that inhibiting the aryl hydrocarbon receptor, or AhR, can promote axon regeneration by shifting neurons from a stress response toward growth.
8:00 PMNatureThe article is an author correction to a mouse-brain atlas designed to provide isotropic 1-micrometre spatial resolution for stereotaxic mapping.

Researchers identified a previously unknown function of the Rb protein, a regulator of cell division, in breast cancer. The finding helps explain why blocking cell division can strengthen signaling through the estrogen receptor, which drives some breast tumors.

German company Isar Aerospace successfully sent its two-stage Spectrum rocket into low Earth orbit from a Norwegian spaceport, marking Europe's first fully commercial orbital launch. The achievement follows a failed attempt in March that ended about 30 seconds after liftoff when the rocket crashed into the sea.
3:04 PMThe Verge
Indonesia’s peat fires are intensifying early in the 2026 fire season as El Niño and severe drought dry out wetlands. The fires can smolder underground for months, emit unusually high levels of fine particles and other pollutants, and evade satellite detection because smoke remains concentrated near the ground.

Anthropic AI ‘formalizes’ proof of Fermat’s last theorem in just 11 days
Summary
Claude produced a 13-million-line, computer-checked formalization of Fermat’s last theorem in 11 days. The result represents a major advance in using AI to translate deep mathematical reasoning into verifiable code.
The key shift is from generating plausible mathematical text to constructing a proof that software

Author Correction: AhR inhibition promotes axon regeneration via a stress–growth switch
Summary
The article is an author correction to research reporting that inhibiting the aryl hydrocarbon receptor, or AhR, can promote axon regeneration by shifting neurons from a stress response toward growth.
The correction changes the record of a finding with potential relevance to nerve-injury treatments, but

Author Correction: A mouse brain stereotaxic topographic atlas with isotropic 1-μm resolution
Summary
The article is an author correction to a mouse-brain atlas designed to provide isotropic 1-micrometre spatial resolution for stereotaxic mapping.
The correction updates the reference dataset used to locate and compare structures across mouse brains,

Probing the proteome at cellular scale
Summary
New technologies can identify thousands of proteins in individual cells, giving researchers a more detailed view of the molecular processes involved in development and disease.
The key shift is from measuring broad protein averages to resolving proteomic differences between individual

The secret life of a cell-cycle gatekeeper of breast cancer
Summary
Researchers identified a previously unknown function of the Rb protein, a regulator of cell division, in breast cancer. The finding helps explain why blocking cell division can strengthen signaling through the estrogen receptor, which drives some breast tumors.
Rb may connect two forces that are usually treated separately: cell-cycle control and estrogen-receptor activity.

Europe has its first commercial orbital rocket
Summary
German company Isar Aerospace successfully sent its two-stage Spectrum rocket into low Earth orbit from a Norwegian spaceport, marking Europe's first fully commercial orbital launch. The achievement follows a failed attempt in March that ended about 30 seconds after liftoff when the rocket crashed into the sea.
Isar Aerospace has moved from a failed demonstration to a verified orbital capability, giving Europe

Indonesia’s most dangerous fires are burning underground
Summary
Indonesia’s peat fires are intensifying early in the 2026 fire season as El Niño and severe drought dry out wetlands. The fires can smolder underground for months, emit unusually high levels of fine particles and other pollutants, and evade satellite detection because smoke remains concentrated near the ground.
The early surge signals a longer and harder-to-detect fire season, not just more visible forest
