Climate change: Sea ice loss linked to spread of deadly virus

Climate change: Sea ice loss linked to spread of deadly virus

Science
The decline in sea ice seen in the Arctic in recent decades has been linked by scientists to the spread of a deadly virus in marine mammals. Researchers found that Phocine distemper virus (PDV) had spread from animals in the North Atlantic to populations in the North Pacific.The scientists say the spread of pathogens could become more common as ice declines further.The 15-year study tracked seals, sea lions and otters via satellite. The loss of sea ice in the Arctic has been one of the most visible signs of climate change on the planet over the past four decades. According to the Intergovernmental Panel on Climate Change, the ice has been retreating by around 12% per decade between 1979 and 2018."These sea ice changes in Septembe...
Bladder cancer ‘attacked and killed by common cold virus’

Bladder cancer ‘attacked and killed by common cold virus’

Health
A strain of the common cold virus can infect and kill bladder cancer cells, a small study suggests.All signs of the disease disappeared in one patient, and in 14 others there was evidence that cancer cells had died.University of Surrey researchers said the virus could "help revolutionise treatment" for the cancer and reduce the risk of it recurring.A bladder cancer charity called the study "very exciting" if larger studies confirmed the findings.Non-muscle invasive bladder is the 10th most common cancer in the UK, with around 10,000 new cases each year.Current treatments for this type of bladder cancer are invasive or can cause serious, toxic side effects.And constant, costly monitoring is needed to check that the cancer has not ...
Largest world stock of animal-killing virus destroyed by UK lab

Largest world stock of animal-killing virus destroyed by UK lab

Science
Scientists have destroyed the UK's laboratory stocks of a virus that once caused devastating cattle losses.These stocks accounted for most of the world's lab samples of rinderpest, which were held at The Pirbright Institute in Surrey.Rinderpest and the deadly smallpox virus are the only diseases to have been eradicated from the face of the Earth. BBC News had exclusive access to the destruction of the final samples. Dr Carrie Batten, from The Pirbright Institute, described the moment as "the end of an era"."Rinderpest was devastating and by removing the stocks that are held globally you are essentially reducing the risk dramatically," she said. Dr Michael Baron, honorary...
Climate change is helping spread a deadly virus among frogs in Britain

Climate change is helping spread a deadly virus among frogs in Britain

Science
May 10 (UPI) -- Earth's warming climate is encouraging the spread of a virus causing a deadly epidemic among common frogs, Rana temporaria. When a team of researchers in England compared the records of mass-mortality events linked to Ranavirus with climate patterns, they found rising temperatures were associated with an increased risk of a viral outbreak. If temperatures continue to rise, scientists expect Ranavirus outbreaks to become more severe and occur more frequently. In addition to analyzing weather and frog mortality data compiled by the Met Office and Froglife's Frog Mortality Project, scientists also studied cell cultures and live models in the lab. Their tests confirmed warmer temperatures increased the likelihood of Ranavirus triggering an outbreak of the fatal disease. The l...
