There are many lies told by politicians when it comes to immigration in the UK, but none is bigger than the claim that it’s all too easy: www.theguardian.com/commentisfre...

Starmer claims to want integration. Yet denying people safety, belonging and the right to vote for a decade amounts to the exact opposite, says Guardian columnist Nesrine Malik

Attention coral reef scientists...
OK, I'm biased... but I'm a big fan of this new paper by @liamlachs.bsky.social, which emerged from his visit to UBC. The message: don't just grab the highest resolution data. You need to evaluate what is suitable for your specific location and research question.

Corals need to be close to their partners to reproduce, just a few meters. This has implications for bleaching event recovery which can leave individuals stranded, hampering reef re-population.

Corals depend on near neighbours to reproduce
A new study reveals corals must be within only a few metres of each other to successfully reproduce, leaving them vulnerable in a warming world.

Our study shows selective breeding is feasible, yet potential heat tolerance gains are modest compared to expected future warming.
R&D is needed to optimise breeding interventions and maximise positive impacts.
Ultimately, reefs still depend on rapid reductions in greenhouse gas emissions.

Offspring bred for short-stress tolerance did not show evidence of enhanced tolerance to the long-term stress that more closely emulates marine heatwaves.
To maximise coral fitness in the face of climate change, care will be needed when selecting which traits to breed for.

Nature vs. Nurture:
The heritability of heat tolerance traits was ~0.2-0.3.
This means these traits have a substantial genetic basis but are also heavily influenced by other non-genetic factors.

Offspring whose parents had high (rather than low) heat tolerance showed an enhanced ability to withstand the type of heat stress for which they were bred.
They can withstand the heat stress for a longer duration before the onset of bleaching and mortality.

Then offspring were reared in an ocean nursery until they reached reproductive maturity themselves at 3-4 years old.
At this stage, the offspring were exposed to the same heat stress tests that were used years before to select their parents.
