Day’s Recap
These developments extend both who can participate in spaceflight and what scientists can observe.

Early observations from the Vera C. Rubin Observatory have identified two previously unknown companions of the Milky Way: an exceptionally faint galaxy and a star cluster obscured by dust. The survey covered only 7% of the sky, suggesting that many more satellite systems could be found.

Evidence suggests Europe was dominated for more than 20 million years by open woodlands, flowering meadows, and large grazing animals rather than continuous dense forest. The finding challenges the assumption that thick forest represents the continent's natural baseline.

Rubin Observatory discovers two hidden companions of the Milky Way. Hundreds more may be waiting
Summary
Early observations from the Vera C. Rubin Observatory have identified two previously unknown companions of the Milky Way: an exceptionally faint galaxy and a star cluster obscured by dust. The survey covered only 7% of the sky, suggesting that many more satellite systems could be found.
The decisive development is the observatory's ability to detect objects that were too faint or

Scientists discover Europe's ancient forests were nothing like we imagined
Summary
Evidence suggests Europe was dominated for more than 20 million years by open woodlands, flowering meadows, and large grazing animals rather than continuous dense forest. The finding challenges the assumption that thick forest represents the continent's natural baseline.
The main shift is from treating reforestation as an automatic conservation benefit to recognizing that

Conservation policy may need to restore a mix of open and wooded habitats instead of simply planting more trees.

A curated list of other prominent stories from this day.
Human respiration produces more than 2 billion metric tons of carbon dioxide each year, a total that has risen 74% in three decades, mainly because the global population has grown. That carbon is part of the natural carbon cycle rather than an added fossil fuel emission, but measuring it could refine climate models.

Researchers are developing mice whose brains contain human cortical cells, creating neurohybrids that could help study neurological diseases and test treatments. The work also raises questions about how extensively human cells integrate into animal brains and whether that could alter cognition or moral status.

Human bodies produce 2 billion metric tons of CO2 a year just by staying alive
Summary
Human respiration produces more than 2 billion metric tons of carbon dioxide each year, a total that has risen 74% in three decades, mainly because the global population has grown. That carbon is part of the natural carbon cycle rather than an added fossil fuel emission, but measuring it could refine climate models.
The increase changes the scale of a biological flux that climate models already account for

‘Alien-cortical’ mice: Can human brain cells grow inside animals?
Summary
Researchers are developing mice whose brains contain human cortical cells, creating neurohybrids that could help study neurological diseases and test treatments. The work also raises questions about how extensively human cells integrate into animal brains and whether that could alter cognition or moral status.
Human brain cells can survive and function inside animal brains, pushing cross-species research beyond a
