UK waters could see surge in shark numbers scientists say, as they seek out new habitats

BRITISH waters could soon see a surge in shark species as they seek out new habitats, scientists say.
These include increasing numbers of basking and spurdog sharks - which can grow up to 1.6 metres - and thornbacks, a type of stingray with spines.

Scientists have mapped out how those at threat of extinction will migrate for a better chance of survival as sea temperatures rise.
The research - undertaken by the Centre for Environment, Fisheries and Aquaculture Science (Cefas) - showed native oysters will be amongst the biggest winners.
Experts say mobile species will cope best, but static creatures could struggle to adapt - with fears the sea pen could lose as much as 40 percent of their habitat by the end of the century.
The ocean quahog, a type of clam that can live more than 500 years, is also predicted to find it harder to adapt.

Bryony Townhill, marine scientist at Cefas, told
"Any changes that we see in our seas are particularly impactful."
She added that movement of the 19 species could result in bigger catches for fishermen in coastal communities.
I went to see basking sharks off Irish coast and I can't believe how lucky I was
Professor John Pinnegar, director of the Cefas Marine Climate Change Centre, said the biggest surprise from the findings was the possibility of native oysters thriving.

"They've been declining and disappearing for 100 years - and yet the climate model suggests they should be doing fine and perhaps even thriving," he explained.
Prof Pinnegar said although there is potential for new habitats, the vulnerable species still need protecting from the likes of fishing equipment, disease and pollution.
Basking sharks are the second-largest living shark after the whale shark, and can grow up to 10 metres, or 32ft.
They are not, however, a threat to humans, and live on plankton.

Sex drug Viagra has surprising new health benefit and could help 3 million ageing Brits, say scientists

SEX aid pill Viagra helps stiffen your skeleton, a study suggests. The little blue tablet was found to increase production of vital bone cells — so could one day prevent back pain and fractures in old age. Advertisement Researchers found sildenafil, which is branded as Viagra, helped human stem cells transform into osteoblasts, the bone-building cells. These are vital as the human skeleton regenerates and is completely replaced roughly once every ten years. As we age, we lose more bone than we build, increasing the risk of breaks or osteoporosis, which makes bones brittle and painful. The Peking University team's follow-up tests on mice also suggested sildenafil would prevent bone loss.

'Sildenafil enhanced stem cell osteogenic differentiation and inhibited bone loss ­— it may usefully treat osteoporosis.' More than three million Britons suffer drugs . They said: 'Any new drug must be evaluated. This is time-consuming, expensive and risky. But sildenafil is approved and safe.'

Ireland's universities among most improved in the world as Trinity retains top place in country's rankings

Trinity College Dublin (TCD) retained its place as Ireland's top institution in the QS World University Rankings for 2026, improving its overall ranking from 87th last year to 75th. University College Dublin (UCD) was ranked 118th, up from 126th a year ago, followed by University College Cork (UCC), up to 246th from 273rd, and the University of Galway, which fell to 284th from 273rd. The University of Limerick, Dublin City University (DCU), the University of Maynooth and the Technological University of Dublin (TUD) made up the rest of the eight Irish universities included in the rankings. Seven of the eight improved on their ranking from a year ago, making Ireland the most-improved country in Europe and the second-most improved in the world, trailing Azerbaijan. This edition of the QS rankings also marks the first time every ranked Irish university has been included in the world's top 800. Further and Higher Education Minister James Lawless said third-level institutions 'play a vital role in delivering education and research' in Ireland. 'This work has been and continues to be pivotal to the success of our country as a knowledge-driven economy,' he said. Their achievements reflect the strength of our higher education system 'I congratulate the institutions that have improved their standing in this year's QS university rankings. 'Their achievements reflect the strength of our higher education system and reinforce Ireland's global reputation for academic excellence and cutting-edge research. 'This progress also reflects the significant investment this Government has made in higher education in recent years, supporting our ambition to build a world-class, innovative and inclusive system that delivers for all.' TCD ranked in the top 100 globally in three indicators: academic reputation, international faculty and graduate outcomes. UCD landed in the top 100 for graduate outcomes and in the top 50 for sustainability, where it was ranked 49th. After rising into the global top 250, UCC also improved in academic reputation, employer reputation and citations per faculty. The University of Oxford was in fourth place, down from third At the top of the rankings, the Massachusetts Institute of Technology (MIT) retained the number one spot it has held since 2012. In second place was Imperial College London, the same spot it earned last year. The University of Oxford was in fourth place, down from third, and Harvard University was in fifth, down from fourth. QS senior vice-president Ben Sowter said: 'Ireland's outstanding results in the 2026 QS World University Rankings are testament to the dedication of academics, administrators and students across the eight universities from the country included in the ranking. 'The Government has been clear in its ambitions to make Ireland a first-choice destination for international learners in its Global Citizens 2030 Talent and Innovation Strategy and, with every university improving in the international student indicator, the country's campuses are increasingly open and diverse.'
