Lab Notes: 1 in 3 women get this infection. To cure it, treat men
For women who get bacterial vaginosis or BV, a common condition that can cause a fishy-smelling discharge, many will get it again (and again).Why some people were prone to recurrent BV was a mystery … until now. Australian researchers have shown that BV-related bugs can be sexually transmitted, and treating male partners significantly cuts recurrence rates.

Lab Notes: More than whale food — krill are climate heroes
Antarctic krill (Euphausia superba) do much more than fill whales' bellies. These tiny crustaceans also play a huge role in Earth's carbon cycle.They sequester around 40 million tonnes of carbon each year, mostly in their poo — that's the equivalent of taking 35 million cars off the road.Yet there's plenty we don't know about these thumb-sized critters.Now a new study has revealed what they get up to under the Antarctic winter sea ice, and how this behaviour affects carbon calculations.Dive into the secret life of krill on Lab Notes, the show that brings you the science of new discoveries and current events.Get in touch with us: [email protected]

What's bowel disease got to do with it? And what might the US expect with an anti-vaxxer at the helm of health and human services?Learn more on Lab Notes, the new show that brings you the science of new discoveries and current events.

Are we simply harder to impress now?Breaking all this down -- and more -- are technology reporters Ange Lavoipierre and James Purtill.
