The feeling of hunger could be a simple way to stop the ageing process, according to a new study. Researchers at the University of Michigan tricked fruit flies into feeling hungry which resulted in the insects living longer – even when they eat their calorie intake. The study - published in Science - suggests that the perception of insatiable hunger alone can generate the anti-aging effects of intermittent fasting. (And since it’s the perception rather than actual hunger, it means the bugs don’t actually have to starve).

"The perception of not enough food is sufficient." You may have heard the term intermittent fasting before, as it is a popular diet fad that consists of going for extended periods of time without eating, followed by a period of eating normally, according to Bupa. Despite its popularity, evidence supporting its benefits is limited in terms of research on humans. Perhaps you’re thinking… why fruit flies? Well, the insects actually share 75 percent of the same disease-related genes as us, while also sharing similar qualities to mammals in terms of their metabolisms and brains, according to Science Alert. In the research, branched-chain amino acids (BCAA) essential nutrients that appear to trigger feelings of fullness in flies when consumed, were used. The fruit flies maintained their hunger through getting fed snacks low in BCAA and their hunger was noticed through how much the insects ate from a buffet of food hours after eating the snack. More food was consumed by flies who earlier ate a low-BCAA snack, and they choose protein over carbs, focusing on what their hungry bodies needed. From learning this, the team directly activated the neurons in fruit flies that trigger hunger responses, they found these hunger-stimulated flies also lived longer. "Demonstration of the sufficiency of hunger to extend life span reveals that motivational states alone can be deterministic drivers of ageing," Pletcher and colleagues wrote in the findings. Along with fruit flies, rodents have also been part of the study and both seems to suggest calorie restriction can extend life and is good for our health too. Though of course, more extensive research is required to see whether or not this is also the case with humans. Have your say in our news democracy.

Since the break up of Pangea that formed the world, we have been taught that there are seven oceans. But now, scientists believe a brand new ocean is currently forming as the continent of Africa is slowly beginning to split in half. Researchers have found two large parts of the land within Africa have begun to separate and it's believed a whole new ocean will form in the divide. Africa is the second-largest continent in the world, with a landmass of more than 30 million square kilometres, and is also the second-most populous. Many of its 54 countries are landlocked, however for some that could be about to change. Geologists believe countries such as Uganda and Zambia could come to have their own coastlines if the two land masses continue to separate. In the peer-reviewed journal, Geophysical Research Letters, experts have confirmed that the split in the African continent is creating a way for a new ocean to form. Sign up to our new free Indy100 weekly newsletter Scientists have identified the exact location where the continent first started to split, very deep underground. The crack first began to appear in 2005 in Ethopia’s deserts. The crack is known as the East African Rift and is 35 miles long. The start is positioned at the meeting point of three tectonic plates which have been gradually pulling apart from each other. Christopher Moore, a Ph.D. doctoral student at the University of Leeds, told NBC News: “This is the only place on Earth where you can study how continental rift becomes an oceanic rift.” Moore and other researchers have used satellite radar to monitor the volcanic activity in East Africa as this is associated with tectonic shifts. Despite being able to monitor movement, the split is a very gradual process, and scientists believe it will take another 5 to 10 million years for the new ocean to fully form.

Threads, Instagram’s new Twitter rival, has now hit 70 million sign-ups, parent company Meta has said. The app is now easily the fastest-growing app in the world, and has seen the fastest growth of any app ever. That position was originally held by ChatGPT, but it took a couple of months for that app to reach 100 million users. It also means that Threads is well on its way to the size of Twitter, its rival. That app had 229 million monthly active users in May 2022, according to a statement made before Elon Musk’s buyout latest last year. Meta revealed the latest sign-up numbers as it looked to highlight high-profile early adopters, including Selena Gomez, Khloe Kardashian and Lewis Hamilton. It did not reveal how many posts had been made on the site, though that is already likely to be in the hundreds of millions. Meta launched Threads – which uses Instagram branding and borrows accounts from the platform – late on Wednesday. Since then it has been growing quickly, with the number of users seemingly doubling every few hours. Dubbed as the “Twitter-Killer”, Threads was the top free app on Apple’s App Store in the UK and US on Thursday. Its arrival comes after Meta chief executive Mark Zuckerberg and Twitter’s Musk have traded barbs for months, even threatening to fight each other in a real-life mixed martial arts cage match in Las Vegas. “The cage match has started, and Zuckerberg delivered a major blow. In many ways, it’s exactly what you’d expect from Meta: Stellar execution and an easy-to-navigate user interface,” Insider Intelligence principal analyst Jasmine Enberg said. Twitter responded on Thursday by threatening to sue Meta, according to the publication Semafor, citing a letter delivered to Zuckerberg by a lawyer for Twitter. Twitter was not immediately available for comment. Reuters could not immediately verify the Semafor report. Meta said no one on the Threads engineering team is a former Twitter employee. Numerous competitors to Twitter have sprung up following Musk’s $44 billion purchase of the social media platform last year, which was followed by a series of chaotic decisions that have alienated both users and advertisers. Musk’s latest move involved limiting the number of tweets users can read per day. Twitter’s stumbles make room for a well-funded competitor like Meta Platforms, analysts and experts said, particularly because of its access to Instagram users and its advertising strength. “Meta’s release of Threads came at the perfect time to give it a fighting chance to unseat Twitter,” said Niklas Myhr, professor of marketing at Chapman University, referring to the turmoil at Twitter after it limited the number of tweets users can see. “Threads will be off to a running start as it is built upon the Instagram platform with its massive user base and if users adopt Threads, advertisers will be following closely behind.” Other competitors have found limited success. Mastodon, another Twitter-like app, has 1.7 million monthly active users, according to its website, while Twitter co-founder Jack Dorsey-backed Bluesky has about 265,000 users.
