Flip. So many thoughts on this.

Scientists warn axing CSIRO jobs will harm climate change response Scientists are calling on the Australian government to push back on a plan to scrap hundreds of jobs at the nation's science agency, as they await the release of further details this week.

Crude oil prices, showing a very sharp increase in the last day, from around 65 to 101 dollars per barrel..

Oil prices wouldn't be all over the news today if more of our economy was powered by local, secure renewable energy.

This isn't an "energy crisis". It's a fossil fuel crisis.

44% of UK electricity came from renewables in 2025. More of that plus an electrified economy => no more oil shocks.

Title: "The Haters"

panel 1.
Two round characters sit in a cinema.
Yellow blob "I hate this!"
Red Blob "Me too!"

Panel 2.
They have left the cinema
Red blob "I hated every minute of that film! It was nothing like the book!"

Panel 3.
"Did you like the book?" asks Yellow.
Red replies "I hated it!" then asks "You?"

Panel 4.
Yellow blob "I've not read it. I hated the film purely on its own merits."

Panel 5.
Red blob "I'll lend you my copy."
Yello blob"That's very kind."

Panel 6.
Caption: "Later"
Yellow, reading the book "I hate this!"
Red (happily) "I knew you would!!"

Because β€œlooking at images, not catalogs” is a dying pastime, the paper includes a tutorial on -how- to interpret images of galaxies. Qualitative information alone can get you a surprisingly long way towards a reasonable model, if you’re thinking through the links between morphology and physics.

A Narrowband Technosignature Search Toward the Hycean Candidate K2-18b Using the VLA and MeerKAT K2-18b, a sub-Neptune exoplanet located in the habitable zone of its host star, has emerged as an important target for atmospheric characterization and assessments of potential habitability. Motivated...

These authors went looking for technosignatures around (in)famous exoplanet K2-18b with 2 of the world's best radio interferometers. They found none, but cool work and great to highlight that these searches are happening. arxiv.org/abs/2602.09553 πŸ”­

Now think about an EV instead. The sun produces energy by fusing hydrogen atoms into helium. It travels 93 million miles in about eight minutes and 20 seconds (seven seconds more when our orbit takes us furthest away). Those photons then strike the silicon atoms in a photovoltaic panel, knocking loose electrons that produce a stream of direct current electricity; an inverter, now usually contained in the panel, converts that to AC power, which can be pumped directly into the battery of an EV where the motor uses electromagnetism to create a rotating magnetic field in a stator, which spins the inner rotor to propel the car. There are about 20 moving parts in the engine, and it is 80 to 90 percent efficient. There is no exhaust and almost no noise. That’s it. And if you poured those electrons into an e-bike instead of an EV, it’s even better: a penny’s worth of power is good for three miles or so. The same principles apply to electric buses, electric ferries, and so on.

Strengthen public education to boost social cohesion

Australia’s school system is becoming more socially segregated. Private school enrolments have grown rapidly over the past two decades, while most public schools remain underfunded β€” weakening one of the country’s strongest institutions for social cohesion. satpa.pe/yX06DOs

Not an 'energy crisis'. People need energy: it keeps them alive. This is a crisis due to forced dependency on the most unreliable and unstable fuel product in human history.
