Scientists have created gene-edited farm animals that could help improve food production and save endangered species.
Pigs, goats and cattle have been engineered so that they become elite species which can produce sperm with traits such as disease resistance and higher meat quality.
Researchers developed the system in mice and then tried larger animals. They used a gene-editing tool to shut the male fertility gene, and then injected sperm-producing cells from donor animals.
A team from the Roslin Institute at Edinburgh University, which created the world's first adult cloned mammal – Dolly the sheep – worked on the "super sires" project with three US universities.
We can get better dissemination of desirable traits
“This shows the world that the technology is real. It removes the need for artificial insemination or any surgical intervention. Your animals become an artificial insemination unit,” said Professor Bruce Whitelaw, interim director at Roslin.
The animals, created using a gene-editing tool called CRISPR-Cas9, are essentially sterile blank slates that could then be transplanted with stem cells that produce the desired sperm, the scientists said.
The process could help farmers rear healthier, more productive animals using fewer resources such as feed, medicines and water, they said.
It could also give breeders in remote regions of the world better access to genetic material from elite animals from elsewhere, allowing for "precision breeding".
"If we can tackle this genetically, then that means less water, less feed and fewer antibiotics we have to put into the animals," said Jon Oatley, a reproductive biologist at Washington State University in the US, who co-led the work.
“We can get better dissemination of desirable traits and improve the efficiency of food production.”
Researchers also said the technology could be used to help endangered species recover. They hoped the technique could use the frozen sperm of an endangered animal to help its kind survive.
Gene-edited animals have not yet been approved for human consumption in the UK, and there are several ethical questions surrounding the possibility.
Dr Helen Wallace, director of the non-profit GeneWatch UK, said the advances came at the cost in the dead animals of failed experiments.
"The process of producing surrogate sires is likely to harm animals, as genetic engineering, including gene editing, involves many failed attempts, particularly in mammals," she told the UK's Telegraph newspaper.
"There are usually multiple stillbirths and early deaths during the process of producing one gene edited animal. In addition, it is still unclear whether this will ever work in farm animals.”
Dolly, born on 5 July 1996, was the world’s first mammal cloned from an adult somatic cell. She had three mothers: one provided the egg, another the DNA, and a third carried the cloned embryo to term.

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.

FFP EXPLAINED
What is Financial Fair Play?
Introduced in 2011 by Uefa, European football’s governing body, it demands that clubs live within their means. Chiefly, spend within their income and not make substantial losses.
What the rules dictate?
The second phase of its implementation limits losses to €30 million (Dh136m) over three seasons. Extra expenditure is permitted for investment in sustainable areas (youth academies, stadium development, etc). Money provided by owners is not viewed as income. Revenue from “related parties” to those owners is assessed by Uefa's “financial control body” to be sure it is a fair value, or in line with market prices.
What are the penalties?
There are a number of punishments, including fines, a loss of prize money or having to reduce squad size for European competition – as happened to PSG in 2014. There is even the threat of a competition ban, which could in theory lead to PSG’s suspension from the Uefa Champions League.
