Reporting in the current issue of Environmental Health Perspectives, researchers at the Centre for Ecology & Hydrology (CEH) describe the likely effects of widespread antiviral treatment for a flu pandemic, on wildlife and the natural environment.
Lead researcher Dr Andrew Singer, said “An antiviral drug has never been widely used before, so we need to determine what might happen. During a flu pandemic, millions of people will all take Tamiflu at the same time. Over just 8 or 9 weeks, massive amounts of the drug will be expelled in sewage and find its way into the rivers. It could have huge effects on the fish and other wildlife.”
The build up of Tamiflu in rivers is likely to cause the avian influenza virus in ducks to become resistant to it, eventually resulting in a new wave of flu that is unaffected by the Tamiflu drug. People in south-east Asia, for example, could be more at risk from contracting the new strain of influenza because they have close and frequent contact with wildfowl.
Dr Singer said, “We hope that, in the short term, Tamiflu will slow the spread of the virus so that an effective vaccine can be produced. But we recommend that more research is done to identify the regions and people most at risk, to study how Tamiflu behaves in water, and to determine cheap and easy ways to break it down before it reaches the river.”
The CEH research has focussed on determining the effects of Tamiflu in rivers in the UK and the USA.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.
How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...
