Coral has been bred to survive intense marine heatwaves for the first time, although scientists stress it is not a “silver-bullet solution” to protect reefs from the effects of climate change.
The breeding programme proves it is possible to boost heat tolerance of adult coral offspring in a single generation, said researchers. But the improvement was only “modest” when compared to future marine heatwaves expected under climate change, they added.
And selective breeding to withstand short periods of heat stress did not appear to enhance the ability of offspring to survive long-term heat exposure, they warned.
Study author Adriana Humanes, a research associate at the Coralassist Lab based at Newcastle University in the UK, said the study represents the first time that corals have been "selectively bred" to enhance the survival of adult colonies when faced with marine heatwave stress. "Our study shows that assisted evolution via selective breeding is feasible, suggesting that current global efforts to develop assisted evolution techniques are warranted," she told The National.
However, study lead author, Liam Lachs, a postdoctoral research associate at the same university, said the work shows that although selective breeding is feasible, it is not a "silver-bullet solution". He said: "The enhancement we achieved was modest compared to the marine heatwaves that are expected to occur in the coming decades. This tells us that selective breeding interventions could have some beneficial outcomes but are not a panacea. Rapid action on reducing greenhouse gas emission is still urgently needed to give corals a chance."
The work provides an important proof of concept, showing that selective breeding could be used to help improve survival amid rising marine temperatures, said Dr James Guest, reader in coral reef ecology at the university’s School of Natural and Environmental Sciences. It might be possible to breed other coral but they might have less predictable spawning times than those in the study, which produce large numbers of eggs and spawn synchronously with quite predictable timing. "First we need to have a better understanding of their reproductive biology," he told The National.
Coral bleaching in Gulf 2024 - in pictures
“How many corals need to outplanted to benefit wild populations? Can we ensure there are no trade-offs – evidence so far suggests this is not a large risk? How can we avoid dilution of selected traits once added to the wild? How can we maximise responses to selection?
“Given the moderate levels of enhancement we achieved in this study, the effectiveness of such interventions will also depend on urgent climate action.” The researchers point out that selective breeding has been practised by humans for thousands of years to produce desirable characteristics in animals and plants.
Coral reefs support the well-being and livelihoods of close to 1 billion people, provide up to $9.9 trillion in ecosystem services, such as coastal protection, as well as boosting jobs and food, tourism and recreation.
Corals in the Arabian Gulf are able to survive at significantly higher temperatures than those in other areas, but they are operating at the edge of their limits and highly vulnerable to marine heatwaves, which can trigger mass bleaching of the kind that was recently discovered in the southern Arabian Gulf.
Last month it emerged there had been a near “total bleaching” of corals from Abu Dhabi to Umm Al Quwain, with about 40 per cent of reefs whitened in Ras Al Khaimah and off Khor Fakkan.
Bleaching occurs when heat stress forces a coral to lose its algae – which provides colour and most of its energy – turning them white. They remain alive but will die if temperatures do not return to normal.
The most recent event represented the fourth global mass bleaching after 1998, 2010 and 2014 to 2018, suggesting they are becoming more frequent, giving corals less time to recover.
Last year featured record sea surface temperatures around the world, in part due to El Nino, the natural weather phenomenon which also drives up the mercury on land. Data showed the weather phase ended in April, however, marine temperatures remained at “an unusually high level”.
Ten tax points to be aware of in 2026
1. Domestic VAT refund amendments: request your refund within five years
If a business does not apply for the refund on time, they lose their credit.
2. E-invoicing in the UAE
Businesses should continue preparing for the implementation of e-invoicing in the UAE, with 2026 a preparation and transition period ahead of phased mandatory adoption.
3. More tax audits
Tax authorities are increasingly using data already available across multiple filings to identify audit risks.
4. More beneficial VAT and excise tax penalty regime
Tax disputes are expected to become more frequent and more structured, with clearer administrative objection and appeal processes. The UAE has adopted a new penalty regime for VAT and excise disputes, which now mirrors the penalty regime for corporate tax.
5. Greater emphasis on statutory audit
There is a greater need for the accuracy of financial statements. The International Financial Reporting Standards standards need to be strictly adhered to and, as a result, the quality of the audits will need to increase.
6. Further transfer pricing enforcement
Transfer pricing enforcement, which refers to the practice of establishing prices for internal transactions between related entities, is expected to broaden in scope. The UAE will shortly open the possibility to negotiate advance pricing agreements, or essentially rulings for transfer pricing purposes.
7. Limited time periods for audits
Recent amendments also introduce a default five-year limitation period for tax audits and assessments, subject to specific statutory exceptions. While the standard audit and assessment period is five years, this may be extended to up to 15 years in cases involving fraud or tax evasion.
8. Pillar 2 implementation
Many multinational groups will begin to feel the practical effect of the Domestic Minimum Top-Up Tax (DMTT), the UAE's implementation of the OECD’s global minimum tax under Pillar 2. While the rules apply for financial years starting on or after January 1, 2025, it is 2026 that marks the transition to an operational phase.
9. Reduced compliance obligations for imported goods and services
Businesses that apply the reverse-charge mechanism for VAT purposes in the UAE may benefit from reduced compliance obligations.
10. Substance and CbC reporting focus
Tax authorities are expected to continue strengthening the enforcement of economic substance and Country-by-Country (CbC) reporting frameworks. In the UAE, these regimes are increasingly being used as risk-assessment tools, providing tax authorities with a comprehensive view of multinational groups’ global footprints and enabling them to assess whether profits are aligned with real economic activity.

Real estate tokenisation project
Dubai launched the pilot phase of its real estate tokenisation project last month.
The initiative focuses on converting real estate assets into digital tokens recorded on blockchain technology and helps in streamlining the process of buying, selling and investing, the Dubai Land Department said.
Dubai’s real estate tokenisation market is projected to reach Dh60 billion ($16.33 billion) by 2033, representing 7 per cent of the emirate’s total property transactions, according to the DLD.

Sinopharm vaccine explained
The Sinopharm vaccine was created using techniques that have been around for decades.
“This is an inactivated vaccine. Simply what it means is that the virus is taken, cultured and inactivated," said Dr Nawal Al Kaabi, chair of the UAE's National Covid-19 Clinical Management Committee.
"What is left is a skeleton of the virus so it looks like a virus, but it is not live."
This is then injected into the body.
"The body will recognise it and form antibodies but because it is inactive, we will need more than one dose. The body will not develop immunity with one dose," she said.
"You have to be exposed more than one time to what we call the antigen."
The vaccine should offer protection for at least months, but no one knows how long beyond that.
Dr Al Kaabi said early vaccine volunteers in China were given shots last spring and still have antibodies today.
“Since it is inactivated, it will not last forever," she said.
