Scientists have made an astonishing discovery that suggests bacteria contain memories to be passed on to future generations. Researchers at the University of Texas and the University of Delaware found that despite having no brain or nervous system, certain bacteria may be able to form memories and remember certain behaviours depending on the available cellular iron. When iron levels are low, bacteria can hunt for local iron in their environment, prompting scientists to believe its memory has evolved, according to Science Alert. "Bacteria don’t have brains, but they can gather information from their environment, and if they have encountered that environment frequently, they can store that information and quickly access it later for their benefit," Souvik Bhattacharyya, the lead author of the recent study said. "We show [...] that a prior experience of swarming is remembered when Escherichia coli encounters a new surface, improving its future swarming efficiency," Souvik explained. "An iron-based memory might offer the advantage of providing a hub connecting various stress responses such as antibiotic survival and biofilms." The 'memories' lasted for around four generations, before generally coming to an end by the seventh. "Before there was oxygen in the Earth’s atmosphere, early cellular life was utilizing iron for a lot of cellular processes. Iron is not only critical in the origin of life on Earth, but also in the evolution of life,” the study author went on to explain. "It makes sense that cells would utilize it in this way."

There's nothing better than a hot bath to warm up and unwind on a chilly winter evening - but water bills don’t come cheap, so it’s more important than ever to make sure you’re making the most of your time in the tub. So how long should we be spending in the bath? Well, a recent study has uncovered that 22 minutes is the optimum length of time to spend in the bath. The study conducted by Victorian Plumbing sought to discover ULTIMATE bath time for relaxation, hydration and a good night’s sleep. There were 20 participants involved in the experiment - half male and half female - who took baths of varying lengths and rated how they felt afterward based on a number of factors. The study concluded that 22 minutes is the optimum amount of time to spend in the tub - to feel relaxed, hydrated, and sleep well after. Soaking should stop at 27 minutes if you don’t want to stay feeling hydrated post-bath, according to the study. This supports the advice of some professionals, who suggest that baths should be no longer than 30 minutes. It was also uncovered that baths impact men and women slightly differently. Women have a better night’s sleep after a longer bath, ideally, 30 minutes long, whereas men sleep better after 19 minutes. Those who felt more relaxed after the baths had scrolled on their phone during their time in the tub, whereas those who watched TV were found to be the least. Sorry to burst your bubble bath lovers, but the findings also suggest that people who take more baths are generally more stressed - although they find them more relaxing than shower- on the whole. “When the nights start getting colder in the UK, we tend to see an increase in Brits looking to buy a bath. And who can blame them? There are a number of benefits of a bath; they’re soothing, and cleansing and studies have even suggested that there are similar benefits to exercise," Brenna Ryan from Victorian Plumbing said about the study's findings. “To help you get the most out of your bath, we conducted a study which found that the optimum time to spend in the tub is 22 minutes - to leave you feeling relaxed, hydrated and sleep like a baby.” How to join the indy100's free WhatsApp channel Sign up to our free Indy100 weekly newsletter Have your say in our news democracy.

HSBC’s app and mobile banking website are down on one of the biggest shopping days of the year. The outage came on the morning of Black Friday, when most large retailers offer significant sales – and customers are even more likely to be checking their balance. Instead, the app showed an error message indicating that service was unavailable. The bank said it was urgently working to fix the issue, which appeared to bring problems across its services. “We understand some customers are having trouble accessing banking services as usual right now,” HSBC said in a statement. “We’re investigating this as a matter of urgency and will share an update as soon as possible.” HSBC offers a status page but it appears to have not been updated. It showed that all services were operating normally – despite the company’s statement otherwise. Those who bank with First Direct may also be affected, since it is a part of HSBC.
