The neurons behind acupuncture’s effect on inflammation, and how antibiotics affect gut bacteria. In this episode: 00:54 The neuronal basis for acupuncture’s effect on inflammation In mice, electroacupuncture has been shown to reduce inflammation, but only when certain points on the body are stimulated.

Oct 13, 2021•26 min•Transcript available on Metacast New data suggests that inexpensive, high-efficiency particulate air (HEPA) filters can effectively scrub SARS-CoV-2 particles from the air in hospital COVID wards. The result validates previous studies carried out in controlled conditions. Currently, HEPA filters are not routinely used in hospital settings, but researchers suggest they could could help mitigate the risk of tramission of airborne viruses. In addition a new study has demonstrated the effectiveness of mask wearing, with surgical ma...
