Freedivers repeatedly experience hypoxia while holding their breath underwater. (Matt Porteous/Stone RF/Getty Images) It's extremely not very good for your brain to deprive it of oxygen. Starved of the oxygen they need to produce energy, your neurons can start dying within minutes, rapidly leading to seizures, unconsciousness, and death in the most extreme cases. A seahorse-shaped region called the hippocampus is particularly vulnerable to this hypoxia. It's deeply involved in forming and retaining memories, as well as our ability to navigate the physical world. Yet there are people in this world who voluntarily and repeatedly put themselves under hypoxia. These are the freedivers, performing an extreme sport that involves holding one's breath for minutes at a time while diving into deep waters. The record for this is held by Croatian freediver Vitomir Maričić, who held his breath for an astonishing 29 minutes and 3 seconds at the bottom of a diving pool. But, puzzlingly, these athletes don't appear to show the impaired memory function we might expect from repeated hypoxia. Now, a team led by neuroscientist Julia Micaux of the University of Paris-Saclay may have figured out how.

Home sellers cut asking prices on more than 3,000 properties a day on average in Britain during September, according to figures from Rightmove shared exclusively with the BBC. The property website said the total was the highest of any month for 15 years and was driven, in part, by a glut of homes on the market and some sellers setting unrealistic expectations. The proportion of listed homes that eventually had a price cut peaked in 2023 and has remained relatively high since. Property portals say buyers are now having to be choosy, with many working to a tight budget as mortgage rates have risen to three-year highs. "Once a home has been on the market for a while and then has a price reduction, some buyers start asking questions, even when there is nothing wrong with the property," said Colleen Babcock of Rightmove. "In a market with so much choice, first impressions matter. "Rightmove data said the average price reduction was nearly 7% - the equivalent of nearly £21,000 cut from a typically valued home. Its data showed that homes that had a price reduction typically took 119 days to find a buyer, compared with 39 days for those listed at one price.
