Science In Action Folgen

The 2024 north Atlantic hurricane season has started with a bang, with Hurricane Beryl traversing the whole ocean, and leaving a trail of destruction across the Caribbean, into Mexico and Texas. Presenter Roland Pease speaks to climate expert Michael Mann of Pennsylvania University about this hurricane season and the role of climate change.And Roland speaks to Amie Eisfeld of the Influenza Research Institute at the University of Wisconsin–Madison, who has been looking at the infection and transmission of bovine H5N1 influenza (bird flu). The virus is shown to be transmitted through the milk of cows with bovine flu to mice and by intranasal exposure to mice and ferrets. The findings are published in Nature this week.Ancient genomics: Neolithic farmers hit hard by the plague. Repeated outbreaks of plague may have contributed to the decline in Neolithic populations in Scandinavia, a Nature paper suggests. The analysis of ancient DNA from more than 100 individuals sheds light on the fate of these farmers around 5000 years ago. Roland speaks to geneticist Frederik Seersholm of the Lundbeck Foundation GeoGenetics Centre in Copenhagen.And a cheap coating that can be painted easily onto the glass of greenhouses converts part of the sunlight spectrum into red light that should boost the rate at which plants grow. Roland joins the chemists and crop scientists to see if there really is a difference with tomatoes and strawberries.Presenter: Roland Pease Producer: Jonathan Blackwell Production Coordinator: Jana Bennett-Holesworth (Image: Hurricane Beryl batters northern Jamaica after killing 7 people in southeast Caribbean.

An injectable antiviral "PrEP" therapy that gives 100% protection against HIV infection. Trials among young women in South Africa and Uganda proved so effective, they were wound up early to accelerate its use. Linda-Gail Bekker of the Desmond Tutu HIV Foundation shares her excitement. A new kind of gene therapy that uses the cell's own “epigenetic” mechanisms to silence troublesome portions of our DNA, tested against the prion protein responsible for some brain diseases. Jonathan Weissman led the research at the Whitehead Institute for Biomedical Research in Massachusetts. Accelerated evolution is being tested in Matthew Nitschke’s labs in the Australian Institute for Marine Science to see if it can help protect natural corals against future global warming. The amazing 4.200 km transatlantic flight of some Painted Lady butterflies – and the extraordinary detective work ecologist Gerard Talavera and team needed to prove it.
