A collage of fourteen by eight squares containing examples of gravitational lenses. Each example typically comprises a bright centre with smears of stars in an arc or multiple arcs around it as a result of light travelling towards Euclid from distant galaxies being bent and distorted by normal and dark matter in the foreground. In some rare cases the smearing is in a complete ring, creating a so-called Einstein Ring.

Exploring future imaginaries for #Venice: A ring dyke that is a hotel-city, resilient to all possible sea-levels.

Could it be funded by a public-private partnership and provide returns with positive social, environmental and economic consequences?

The Tropical Forests Forever Facility (TFFF) offers a promising global mechanism to reward global forest conservation, but its success depends on strengthening ecological and social equity, governance and benefit-sharing while preserving its simplicity www.nature.com/articles/s41...

This is figure 2. Elevation profiles of the Venice lagoon boundaries outlining the elevation of primary defenses with respect to the present lagoon and sea level: dike (1) and seawall (2) on Pellestrina barrier island; dunes (3) and embankment (4) on Lido barrier island; dunes and embankments along the northern littoral (5); and embankments protecting the polders along the lagoon border (6, 7, 8).

A paper in Scientific Reports presents four potential strategies — including movable barriers, ring dikes, closing the Venetian Lagoon, and relocating the city — that could help Venice adapt to future sea-level rise over the next 300 years. go.nature.com/4cvTWK3 🌍🧪

Interesting that between gates in the same airport it can easily take the same.

It's indeed the right time to take the CS route for extremes, we should build an alliance.

I'm a long-time advocate of road user charging, but I actually think right now is not the best time.

They should've done it years ago, before the crisis. But right now, when we're in the middle of a significant cultural shift in attitudes to EVs? I'd prioritise not interrupting that.

Geopolitics is accelerating renewables, and our research on social tipping dynamics shows we could accelerate that momentum even further.

How to turn that momentum into a cascade of rapid, self-sustaining change? Ideas welcome!

What's the best thing you can find in a lunar mission? “We came all this way to explore the Moon, and the most important thing is that we discovered the Earth” said Anders after Apollo 8.

Imagination in future co-creation can help putting human wellbeing ahead of short-sighted cost-benefit analyses.

Peak humans?

This is good news:
1. BECCS at Drax would be the biggest risk to a credible, targeted UK CCS program.
2. A focus on batteries and flexibility will better support renewables deployment.
3. Further proof that big emitters like to hide behind the idea of future CCS, but pull back from delivery.

What is the role of the University in a world of “AI everywhere”?

New in the Journal, @katyhayward.bsky.social argues why universities matter more than ever in a world shaped by AI, as spaces for cultivating critical thinking and intellectual independence.

A study by @lapersanc.bsky.social from ICTA-UAB reveals that 73% of wages were generated in Germany, but not 63% of emissions or 54% of the work.

Ebike and e-scooter fires in UK rise to new record highs At least 432 ebike fires and 147 e-scooter fires recorded in 2025, up 38% and 20% respectively on previous year

579 fires!!!

Ebikes and e-scooters involved in fires were “always cut-price products sold through online marketplaces with lax quality control".

Saxifraga longifolia, also known as king's crown or Altamira, is a flowering plant species belonging to the Saxifragaceae family, native to the Pyrenees and the calcareous Pre-Pyrenees, where it arrived during the first ice ages a million years ago.

I loved seeing again this high-mountain Pyrenean endemic species.
