Hope For Coral Reefs After IVF Colonies Survive Record Heat Event
Young corals bred using in vitro fertilisation (IVF) and planted in reefs around the US, Mexico and the Caribbean have surprised scientists, after most survived last year's record marine heatwave, while older corals struggled.

From a report: A study has found that 90% of the young IVF-created corals surveyed remained healthy and colourful, holding on to the algae that live within them and supply them with nutrition. Rather than producing exact clones, as fragmentation does, breeding corals by IVF increased the genetic diversity, giving them a higher chance of adapting to heat over time. The 771 young corals in the study -- a fraction of the thousands bred each year by Secore and partner institutions -- live in restored reefs off Mexico, the Dominican Republic, the US Virgin Islands, and the Dutch Caribbean territories of Bonaire and Curacao.
