A *huge* vaccine victory. I've been writing on this for years; Australia has seen remarkable progress in cervical cancer prevention with the HPV vaccine. I love seeing science triumph like this.
Australia recorded ZERO cases of cervical cancer in women under 25 for the first time since they started tracking the cancer in the 80s.
This is the power of vaccines.
The HPV vaccine is extremely effective at preventing cancer.
Viruses can be oncogenic. Get your vaccines and protect yourself!

newsGP - Australia set for world-first cervical cancer elimination
Vaccination programs have played a key role, and GPs remain ‘instrumental’ in boosting screening rates to reach the 2035 target.

A (dark matter) Space Oddity:
We have an exciting new paper led by @pengfeili.bsky.social: arxiv.org/abs/2511.17705
He used the best data on the Milky Way rotation curve from Gaia to infer not the current, but the *primordial* dark-matter halo of the Galaxy.
And it is quite odd. 🧪🔭☄️

The odd primordial halo of the Milky Way implied by Gaia. A shallow core, but a steep decline
Primordial dark matter halos are well understood from cold dark matter-only simulations. Since they can contract significantly as baryons settle into their centers, direct comparisons with observed ga...

A team demonstrated that more than 80% of moss spores left on the outside of the ISS for nine months and brought back to Earth germinated normally. The findings confirm that moss spores, already known to be hardy, handily survive the stresses of near-Earth orbit. 🧪 👩🔬

Never forget: At breakneck speed we are leaving the stable Holocene climate in which human society developed and thrived. Weather extremes are outside historical experience. Sea-level rise is accelerating. Dangerous tipping points are ahead.

"It could be that Apple has configured the power-saving mode too aggressively in an effort to maximize battery life."
Very tentative of course, but matches my pet peeve: many smartphones have batteries that are way too small. Having to recharge daily is actually ridiculous.

Good reminder that there are some amazingly big and complex Earth science missions in orbit. They should get more public attention (in my opinion).

The teams at ESA mission control will now spend around 10 hours carefully unfolding Copernicus's Sentinel-1D’s 12 m radar and two 10 m solar wings. The satellite’s unique deployment sequence was designed to ensure that these complex structures all deploy in the safest possible way.

Germany Blocks EU Chat Control Proposal, Noting That Mass Surveillance Of Encrypted Messages Must Not Be Allowed
Just days after we wrote about the EU's renewed push for chat control, Germany has delivered a very important "no" vote. During discussions with EU countries last Wednesday, Germany's opposition was decisive enough to kill the proposal's momentum and remove it from this week's agenda for EU justice ministers. But it wasn't just a procedural objection—Germany's Justice Minister Stefanie Hubig delivered a statement that drew a very clear and very important line regarding encryption:
