New publication in Environmental Research Letters: overshooting 1.5°C then cooling back down does not undo the damage. We map where, for whom, and through what mechanisms temporary overshoot becomes permanent loss. Paper (OA): iopscience.iop.org/article/10.1... 1/12
"Three stacked panels sharing a time axis. Top: global temperature rises past 1.5°C, peaks, then declines (the overshoot pathway), with a flat permanent-exceedance line at the peak for comparison. Middle: biophysical responses to the same trajectory diverge; some track temperature down, some recover with a lag, one keeps intensifying. Bottom: socioeconomic impacts of the same biophysical change diverge by adaptive capacity; high-capacity systems recover, while one crosses a dashed adaptive-capacity threshold and never recovers: the permanent overshoot legacy.

🌊🧪 Marine snow particles sinking from the surface ocean are critical for deep sea food webs and the oceanic carbon cycle. How fast they sink determines how much carbon reaches the deep ocean, but measuring their speed directly in the field is a challenge in oceanography.

A massive marine heat wave in the Pacific, spanning an area 8x the contiguous US, is expected to intensify storms, exacerbate heat waves on land, and raise sea levels, particularly along the California coast. Climate change will increase the frequency and intensity of marine heat waves.

The Pacific Ocean is running a fever. Why that’s an ominous sign.
A marine heat wave covering an area eight times the size of the United States could soon fuel serious storms and extreme heat.

 www.biorxiv.org/content/10.6... (1)
A visualisation of Bayesian optimal designs for Monod (nutrient) curves at four different sample sizes, and a comparison of those designs against a uniform design using 1000 simulations per sample size. Across all 4 sample sizes, the Bayesian optimal design outperformed the uniform design for parameter estimation in >80% of simulations. We quantified this using the Energy Score, a generalisation of the Mean Absolute Error that applies to distributions and multiple parameters. See preprint for details.

A biologically parameterized model of growth and honest measurement error in the mix. This paper is a quantum leap in handling diverse and messy cross-cultural and archaeological data on human growth, where papers usually fit arbitrary polynomials and ignore measurement error. Link in quote
Height and weight data simulated for 30 individuals measured every year from birth to
age 25 using equations 1 and 2. Parameter values defining the simulated mean cumulative
growth trajectory and five component functions are derived from Matsigenka girls, while
individual-level variance around the mean trajectory is derived from U.S. girls. The prior growth
trajectory (red) used to fit the model to the simulated data is derived from the mean trajectory of
U.S. girls. Corresponding mean cumulative velocity trajectories in green and orange are
decreasing (after age 14) from left to right. Bunce et al. (2025) explains the complications of
fitting (and simulating) weight data using the model.

It’s an RNA world. RNA is posited to be the first genetic material, arising 4 billion years ago. It can store information and act as an enzyme. Eventually, it duplicated its information into a more stable form, DNA.

1960s
LIFE IS BASED ON DNA, WHICH USES RNA TO MAKE PROTEINS THAT DO STUFF.

1980s
ALSO, THE RNA DOES SOME STUFF ITSELF, WHICH IS WEIRD.
