Talk Evidence - excess deaths, the ONS, and the healthcare crisis
In this week's episode, we're focusing on covid and the ongoing crisis in the NHS.
Helen Macdonald, Juan Franco and Joseph Ross cast their evidence seeking eyes over research into outcomes as well as the workload of doctors.
Firstly, Joe tells us about a new big data study into longer term outcomes after mild covid-19, how those ongoing symptoms relate to long covid, and how often they resolve themselves.
Juan looks back to his homeland to see what Argentina which was very early to offer children vaccinations against covid-19. He tells us how a new study design can help understand how effective different combinations of...

Laser 'lightning rod' diverts strikes high in the Alps
In this episode:00:45 Laser-guided lightningScientists have shown that a specially designed laser can divert the course of lightning strikes in a real-world setting. The team fired the laser into the sky above a communications tower high in the Swiss Alps and altered the course of four strikes. In future they hope that this kind of system could be used to protect large infrastructure, such as airports.Research article: Houard et al.News: This rapid-fire laser diverts lightning strikes09:36 Research HighlightsThe crabs that lean on bacteria to detoxify sulfur from hydrothermal vents, and how a persons’ nasal microbes migh...
