Concerning viruses found in fur farmed animals

Science In Action ·

2024/09/05

A Chinese survey of diseased animals farmed for their fur – such as mink, foxes and raccoon dogs - has revealed high levels of concerning viruses, including coronaviruses and flu viruses, many of which appear to jump easily from species to species. John Pettersson of Uppsala University discusses the threat to us humans. We learnt early on in the Covid-19 pandemic how important the genetic details of the virus were in tracking the spread and spotting new variants. The vaccines were designed from gene

Wow! A mystery signal solved

Science In Action ·

2024/08/29

In 1977 astronomers recorded a brief and strange radio transmission that looked like it perhaps had even come from an alien civilization. It was named the Wow! signal – because that’s what astronomer Jerry Ehman wrote on the computer printout upon its discovery. But now a team including Abel Méndez of the University of Puerto Rico at Arecibo have come up with an astrophysical hypothesis. An oil tanker which was attacked by Yemen's Houthi rebels in the Red Sea last week is still on fire and may be

Fisheries mismanagement uncovered

Science In Action ·

2024/08/22

Fishery assessment models – the “backbone” of fisheries management – overestimate the sustainability of the world’s fisheries, according to a study of 230 fisheries worldwide, and populations of many overfished species are in far worse condition than has been reported. We hear from Rainer Froese of GEOMAR - Helmholtz Centre for Ocean Research Kiel. The lunar south pole contains evidence of ancient magma ocean. An analysis of lunar soil in the Moon’s southern high-latitude regions, performed using

The spread of rabies into Cape fur seals

Science In Action ·

2024/08/15

In June this year there was the first detected occurrence of rabies in Cape fur seals, discovered after a rabies case in a dog that had been bitten by a seal. Professor Wanda Markotter, Director of the Centre for Viral Zoonoses at University of Pretoria, has been trying to work out how the virus spread into seals and how to keep people (and their pet dogs) safe. The Japan Meteorological Agency issued a seismic “advisory” last week alerting local authorities and the public to a heightened risk of a

2024/07/25

The near extinction of vultures in India may be responsible for an additional half a million human deaths between 2000 and 2005. The widespread use of the painkiller diclofenac in herds of cattle, starting in 1994, led to a massive decline in vulture populations in India, as the drug is poisonous to them. We hear from environmental economist Anant Sudarshan of Warwick University. Cooking like a Neanderthal - Mariana Nabais of the Catalan Institute of Human Paleoecology and Social Evolution has been

2024/06/13

With mice being the latest species to carry the disease, pandemic expert Rick Bright calls for stronger counter measures. “It’s like PTSD from February 2020” he says. The authorities in the USA are responding too slow to the spread of H5N1 bird flu through its dairy farms – even mice are carrying the virus now, and not enough is known of how it is evolving and whether humans are threatened. He talks Roland through the complex political and public health issues. Child sacrifices in the Mayan empire a

The roots of fentanyl addiction

Science In Action ·

2024/05/23

Fentanyl is a powerful morphine substitute, but it is also incredibly addictive – millions struggle with weaning themselves off it. And of the 600,000 drug deaths worldwide each year, the World Health Organisation estimates 80% are due to opioids in general, with synthetic opioids like fentanyl being a growing part of the problem. New work with genetically manipulated mice suggests that fentanyl affects two parts of the brain, one associated with the high, but also another that regulates fear. This

2024/05/09

Could future blood transfusions be made safer by mixing in a new bacterial enzyme? Every year 118 million blood donations need to be carefully sorted to ensure the correct blood types go to the right patients. Prof Martin Olsson, of Lund University in Sweden, and colleagues in Denmark have published a study that suggests an enzyme made by bacteria in our gut could edit our blood cells to effectively convert type A, B and AB to type O. This would be a step towards a universal blood type that could be

As bird flu is found in US farm cats fed on raw cow’s milk, chimpanzees are observed eating infected bat dung instead of vegetables. There is a constant threat of infections crossing from species to us and also from species to other species, particularly because of what we do. That is, after all, what happened to start the pandemic.We hear about the ongoing struggles of the Chinese virologist who broke his instructions in China in order to share the first COVID genetic data.And a strange tale of how
