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). Sign up to our free Indy100 weekly newsletter "We've sort of divorced [the life extending effects of diet restriction] from all of the nutritional manipulations of the diet that researchers had worked on for many years to say they're not required," physiologist Scott Pletcher said, as per Michigan Medicine. "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.

The remains of a church from a sunken town known as the 'Atlantis of the North Sea' has been discovered beneath the mud on Germany's coast. The church is believed to be part of a site called 'Rungholt' located in the Wadden Sea. The town, which was previously thought to be a local legend, has not been seen since 1362 after it was submerged beneath the waves during an intense storm. However, new research has shown that the town really did exist and that they had built reinforcements around the settlement to protect them from the severe elements. The research was carried out on the area by archeologists from Kiel University, Johannes Gutenberg University Mainz, the Center for Baltic and Scandinavian Archaeology, and the State Archaeology Department Schleswig-Holstein. Sign up to our free Indy100 weekly newsletter Searching the Wadden Sea which is the longest stretch of intertidal sand and mud flats on Earth, the team, using geophysical imaging technology found man-made mounds that had been constructed to protect the town against the tides. Amongst this structure were the foundations of a building which the team determined had to be a church which may have been the location of the town centre. In a statement, Dr. Dennis Wilken, a geophysicist at Kiel University of Kiel University said: "Settlement remains hidden under the mudflats are first localized and mapped over a wide area using various geophysical methods such as magnetic gradiometry, electromagnetic induction, and seismics." Dr. Hanna Hadler from the Institute of Geography at Mainz University added: "Based on this prospection, we selectively take sediment cores that not only allow us to make statements about spatial and temporal relationships of settlement structures, but also about landscape development." Dr. Ruth Blankenfeldt, an archaeologist at ZBSA also suggested that the "special feature of the find lies in the significance of the church as the centre of a settlement structure, which in its size must be interpreted as a parish with superordinate function." The storm that washed away Rungholt has gone down in history as one of the largest to ever hit the region, affecting not just Germany but also the Netherlands, Denmark and the UK. The storm happened on January 1362 and has since been referred to as "the great drowning of men." According to historical reports, Rungholt was once a busy trading port for fishermen but was also populated by taverns, brothels and churches. Have your say in our news democracy.

A revelation about pineapples only made noticeable thanks to a TikTok account and a microscope, has people reevaluating whether they are allergic to the fruit or not. You may have noticed that whenever you've eaten a chunk of the delicious citrus fruit, you are sometimes greeted with an odd tingling sensation in your mouth. Well, if you've ever been curious about what that actually is then the TikTok account SF Microscopy is here to help. The account analyses all sorts of things under a microscope and exposes all the fascinating and dare we say worrying things that lie within everyday objects that the naked eye cannot see. One of the biggest videos on the account, with 35 million views, is about a pineapple. Sign up to our free Indy100 weekly newsletter In the caption, the person behind the account writes: "One of my favorite fruits is pineapple, but every time I eat them, my mouth tingles. I read that the fruit contains raphides! Kiwis, grapes, taro, and yams also have large amounts of these crystals. These needles serve as a defensive function against insect herbivores to deter them from eating the plant’s fruits and protect the seeds. The needles work with other chemical substances, like bromelain in the pineapple, to amplify the effects." If that sounds a bit farfetched then take a look at the video for yourself and you might find that its even more alarming than you might have imagined. @sf_microscopy One of my favorite fruits is pineapple, but every time I eat them, my mouth tingles. I read that the fruit contains raphides! Kiwis, grapes, taro, and yams also have large amounts of these crystals. These needles serve as a defensive function against insect herbivors to deter them from eating the plant’s fruits and protect the seeds. The needles work with other chemcial substances, like bromelain in the pineapple, to amplify the effects. #microscope #microbiology #underthemicroscope #microscopy #microcosmos #nature #pineapple #crystals #fyp #fypage #fypシ The fact that these needles are real has people second-guessing the feeling they experience when they eat pineapples. One person wrote: "My mouth be sore as hell after going crazy on them pineapples & kiwis." Another added: "So ummmm…I’m not allergic to pineapple????" A third said: "Makes sense that when i accidentally inhaled pineapple juice i just about died." While a fourth person said: "It’s gonna stop me i dont feel like being stabbed." Will you stop eating pineapples now that you know this? I think this writer might be willing to live in blissful, delicious ignorance. Have your say in our news democracy.

It feels like every day there’s a science story that comes along ready to blow our tiny minds, and today is no exception. A series of ancient interconnected cities have been discovered in the remote El Mirador jungle Guatemala, and it’s changing our entire understanding of the ancient civilisation. More than 400 settlements have been uncovered with some dating back as far as 1,000 BC. They’re linked by roads too, and it’s led them to be described as “the first freeway system in the world”. Sign up to our free Indy100 weekly newsletter Richard Hansen, a research professor at the University of Idaho, is an expert on the project and he’d called the findings a “game-changer”. It was previously thought that the Mayan peoples were nomadic, but these cities have changed the scientific community’s understanding. Speaking to the Washington Post, Hansen said: "We now know that the Preclassic period was one of extraordinary complexity and architectural sophistication, with some of the largest buildings in world history being constructed during this time.” On top of the 110 miles of interconnected roads, the discoveries also showed evidence of organised agriculture and even hydraulic systems. The findings are the result of work which first began in 2015, which saw lidar technology uncovered signs of ancient structures below the surface. Archaeologist Enrique Hernández, from San Carlos University said about the findings: “Now there are more than 900 [settlements]… We [couldn’t] see that before. It was impossible,” he said.
