Hello lovely people. I know this is very regionally specific, but for anyone in Nelson/Tasman...

Theatre Royal is hosting a play about the Nelson Tenths as told by the wonderful Donna McLeod and I'm going to see it tomorrow. If you see me, please say hi!

Fig. 3.Simplified model for photoperiod sensing in plants. (A) The transcription of a photoperiod sensor is regulated by the circadian clock and light signals (black arrows). The protein stability of the sensor is regulated by light (magenta arrows). The sensor can act negatively (short-day responses) or positively (long-day responses) on the accumulation of a mobile signal, which moves to the meristem to trigger developmental responses. (B) Simplified model of long-day induction of flowering in Arabidopsis. The transcription of CO is controlled by the clock and light signals such that its mRNA peaks at the end of the light period. Light is needed for the stabilization and accumulation of CO protein, so that it only accumulates during long days enabling the production of the mobile signal FT (FLOWERING LOCUS T).

⏰ DARWIN REVIEW ⏰

Feke & Farré summarize evidence for the circadian clock's adaptive role in wild plants, exploring the hypothesis that variation in clock output pathways drives different phenotypic responses, permitting the use of different life history strategies to optimize growth and survival.

Facts matter: big batteries in Aust are LiFePO (lithium iron phosphate chemistry). No cobalt, no nickel.

Likewise EVs.

Their goal was to create fairer HECS‑HELP repayments based on expected career earnings across 24 fields, assuming total funding to each discipline & institution would stay largely unchanged."

Should this plant be declared one of the worst weeds in Australia? Without a national policy, the spread of smothering buffel grass will continue unchecked.

The answer is clearly YES. It should have happened years ago. This invasive plant is an environmental and cultural disaster, and we should throw as many resources as possible towards its suppression or, where possible, eradication.

A black-and-white studio portrait photograph of Emma Lucy Braun, the pioneering American botanist and plant ecologist widely regarded as one of the most influential scientists in the study of eastern North American forests. Shown from the shoulders up against a soft, neutral gradient background, Braun appears in her later years with a calm, intelligent gaze directed straight at the viewer. Her white hair is neatly styled and swept back from her face, and she wears delicate round wire-rimmed glasses. A gentle, knowing half-smile softens her expression, conveying quiet authority, warmth, and scholarly poise. She is dressed in a light-colored, pleated blouse with a gathered neckline and a prominent dark floral brooch pinned at the center of her chest; the visible sleeve features subtle decorative patterning. The tight, centered composition focuses entirely on her face and upper torso, creating an intimate and dignified mood that emphasizes intellect and dignity over ornamentation.

The painting titled “Above and Left” (“Oben und links”) was created by Wassily Kandinsky in 1925. Kandinsky, a pioneering abstract artist, helped define geometric abstraction. The artwork exemplifies this style through colors, lines, and shapes rather than real-world objects.

Trump is acting here as a private citizen while exploiting the office to unofficially coerce govt institutions into giving him and his family obscene amounts of American taxpayer cash.

'Official acts' immunity will therefore not protect him for this brazen corruption.

They should all be jailed.

Honestly, the idea that the market that has utterly pummeled the environment is now going to magically be its saviour, is equal parts idiotic and insulting.

Many governments, including Australia, can and should massively increase environmental and conservation spending, it's an *investment*.

Pancreatic cancer mRNA vaccine shows lasting results in an early trial Scientists caution that more research is needed, but nearly all of the patients who responded to the personalized vaccine are still alive six years later.

My father survived a year with pancreatic cancer but it was a year of terrible suffering. This is very encouraging news.

Today marks 10 years since the death of Josh Park-Fing at a Work for the Dole site in Toowoomba.

Josh died while participating in forced, unpaid labour.

A court later found that Josh's Work for the Dole site did not meet basic safety standards, yet no one was held accountable.

Mr Chalmers goes to Washington Jim Chalmers flew to the International Monetary Fund’s spring meetings this week in the American capital. It was there almost 20 years ago that his former boss, Wayne Swan, noted the early panic surrounding what became the global financial crisis.

Editorial: The way the IMF’s message was picked up in Australian media, you’d think this wasn’t one of the only developed countries to avoid both global recessions this century. As if government support in the tens of billions, with programs like JobKeeper, hadn’t played a part… satpa.pe/eYHiSg8
