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.

Volodymyr Zelensky is likely going to meet Joe Biden at the White House and also visit Capitol Hill in a diplomatic trip to Washington next week, suggested several media reports. The Ukrainian president’s second visit to the US since Russia’s invasion comes at a time Congress is mulling Mr Biden’s request to assist Ukraine with as much as $24bn (£19bn) in military and humanitarian aid. The visit also comes when Western leaders have defended Ukraine’s counteroffensive against Russia, that officials under the condition of anonymity have said has been slow to take off. On Friday, Ukraine announced it had liberated a village near Bakhmut in a “lightning operation” after fierce fighting with Russian troops amid its counteroffensive. Mr Zelensky will meet the US president at the White House next Thursday, an administration official said on the condition of anonymity. Two congressional aides confirmed the war-time president’s trip to the Capitol. The two leaders could also attend a meeting of the UN General Assembly (UNGA) in New York to be held on 18-19 September. The White House National Security Council, however, has declined to comment on Mr Zelensky’s plans. That includes the likely meeting between the two presidents at the White House. This will be Mr Zelensky’s second visit to the US and also be only the second time he has ever visited any country abroad since the invasion in February last year. He had made a grand visit to the US in December last year and delivered an address to the US House of Representatives. In a bid to boost Ukraine’s military capabilities, Mr Biden sought a package of $13.1bn in additional military aid and another $8.5bn for humanitarian support, which also includes $2.3bn for financing and to catalyse donors through the World Bank. However, he is faced with pushback from conservative Republican lawmakers who have been calling for broad federal spending cuts and some of those allied with Donald Trump as they specifically look to stop money to Ukraine. The Congress is facing increasing strife over providing additional funding for Ukraine as the war is well into its second year and working to pass its annual appropriations bills before the 30 September deadline to keep the US government running. Mr Zelensky is likely slated to deliver a speech to the UNGA and also reportedly looking to hold meetings with other visiting world leaders. This has been claimed by Israeli prime minister Benjamin Netanyahu, who said he planned to meet Mr Zelensky on the sidelines of the UN meetings. Additionally, the US is looking to impose new sanctions on more than 150 individuals and entities related to Russia’s invasion of Ukraine. “The US was continuing our relentless work to target Russia’s military supply chains and deprive (Russian president Vladimir) Putin of the equipment, technology, and services he needs to wage his barbaric war on Ukraine,” Treasury Secretary Janet Yellen said.
