The black bit at the end of a banana is not as gross as you might think
When you chow down on a banana, you might often see a black bit at the end and it looks a bit gross. But what is it? Some people think it is the seed, but these are found down the middle, if at all, as the Cavendish variety of bananas, which is commonly sold typically doesn’t produce any seeds. It is actually something completely different. Bananas are technically berries and the black bit is the nub of the flower from which the giant banana berry grew. Bananas grow on trees in bunches, and the end is actually the top of the fruit while the hard stalk is the bottom. But given most people eat bananas by snapping off the stalk first, the residual flower nub is left at the end. This black bit is entirely edible but people often throw it away because it has a tough texture and a bitter taste. So now you know, there is nothing stopping you from getting one of your five a day.

Scientists believe they have found a cure for alcoholism
Alcohol addiction ruins millions of lives every year, but scientists may have found a cure for this terrible affliction. A new treatment for alcohol use disorder (AUD) has been trialled in monkeys with impressive results and, if these translate to human trials, the impact could be monumental. A team of neuroscientists and physiologists from across the US tested a new type of gene therapy to see if they could directly target the underlying brain circuitry associated with sustained heavy drinking. As they noted, in the journal Nature Medicine, people suffering from AUD commonly return to alcohol use even if they attempt to quit. This is largely to do with what’s known as mesolimbic dopamine (DA) signalling – meaning how the central nervous system circuit communicates the feelgood neurotransmitter dopamine. A protein called glial-derived neurotrophic factor (GDNF) is key to keeping these neurons in this reward circuitry functioning. However, experts have found that levels of GDNF are reduced in people with AUD during periods of alcohol abstinence, most notably in a region of the brain called the ventral tegmental area (VTA), as IFLScience notes. Therefore, the researchers decided to test whether using gene therapy to deliver more GDNF to the VTA could help reinforce this crucial dopaminergic signalling and prevent patients from suffering an alcoholic relapse. The team of scientists explained how alcohol consumption in non-addicts prompts the release of dopamine, creating a pleasurable buzz feeling, but chronic alcohol use causes the brain to adapt and stop releasing so much dopamine. “So when people are addicted to alcohol, they don’t really feel more pleasure in drinking,” Dr Kathleen Grant, a senior co-author of the study, said in a statement. “It seems that they’re drinking more because they feel a need to maintain an intoxicated state.” For their research, Dr Grant and her colleagues used eight rhesus macaque monkeys, who were exposed to increasing concentrations of alcohol over four 30-day “induction” periods. The monkeys then had free access to alcohol and water for 21 hours a day for six months, during which they developed heavy drinking behaviours. This was then followed by a 12-week abstinence phase, with the GDNF treatment performed four weeks in for half of the subjects. The gene therapy was delivered using a a viral vector containing a copy of the human GDNF gene injected directly into the primate’s VTA, according to IFLScience. And the results were truly jaw-dropping. “Drinking went down to almost zero,” Dr Grant said. “For months on end, these animals would choose to drink water and just avoid drinking alcohol altogether. They decreased their drinking to the point that it was so low we didn’t record a blood-alcohol level.” The most exciting aspect of their findings is the suggestion that gene therapy could offer a permanent solution for people with the most severe cases of AUD. This will be a welcome glimmer of hope to many, given that some 29.5 million people were diagnosed with AUD in the US alone in 2021, according to the National Institute on Alcohol Abuse and Alcoholism. Of these 29.5 million sufferers, almost a million (894,000) were aged between 12 and 17. It’ll likely be some time before we know for sure whether the gene therapy can be rolled out in humans, but it’s an important first step in tackling this devastating disorder.

Toilet invented that is so slippy nothing can leave skid marks
A 3-D-printed toilet has been invented and the surface is so slippery that nothing can leave a mark on it. Cleaning the toilet has to be one of the grimmest household chores, but thanks to new material, you may never have to scrub a loo again. The toilet is the invention of Yike Li at Huazhong University of Science and Technology in Wuhan, China, who, alongside colleagues, invented a toilet whose surface is so slippery that nothing stains it and uses less water for each flush. The team created a prototype of the toilet around 10 times smaller than a real one. It was made using 3D printing technology, where particles of plastic and hydrophobic sand grains were fused together with lasers. The surface of the toilet was lubricated with a type of silicon oil that also penetrated the surface due to the complex structure of the material. The team tested the toilet with a variety of substances, including honey, yoghurt, muddy water as well as synthetic faeces. They found that none of the substances stuck to the toilet bowl. Amazingly, the toilet was just as slippery after having been rubbed with sandpaper over 1,000 times, which Li believes is due to the oil being able to penetrate the material of the toilet. Li believes the technology would be suited for settings in which a toilet gets a lot of use, such as on modes of transport and in public toilets. He explained: “The reduced flushing volume would result in less wasted water during transportation to the processing facilities, thereby saving transportation costs.” But, before that can happen, Li says the technology needs to be adapted for use on a full-sized toilet and also needs to be cheaper to make.

Why you should delay your first coffee of the morning
For a lot of people, coffee is one of the few things that gets them out of bed and out the door in the mornings. But while it’s tempting to whack the kettle on first thing, a health expert has stated that delaying our first coffee of the day could be much more beneficial to our health. Nutritionist Gabi from The Fast 800 urged people to wait at least 90 minutes before getting their first coffee hit [via the Mirror]. Gabi claims that we can all boost energy levels by doing so. In fact, eating on an empty stomach could even cause your body to enter stress mode and release hormones like adrenaline and cortisol. "Supporting your morning coffee routine with some smart practices can be a game changer for your overall well-being,” Gabi said. She recommends drinking water, as well as eating a meal packed with fibre and protein to balance sugar levels. “Elevated blood sugar can trigger inflammation and set us up to be on a blood sugar roller coaster for the rest of the day, thereby tanking our energy supply,” the health guru said. "Within the first hour of waking, our cortisol levels ideally acutely rise and fall in a response known as our cortisol awakening response. This rise and fall of cortisol represents a healthy nervous system and actually has a big influence on our immune health and even the risk of autoimmune development." She also states that delaying coffee for a minimum of 90 minutes promotes high energy levels. Gabi said: "Morning light exposure is a huge regulator of circadian rhythm and light exposure triggers the healthy release of cortisol in the morning to support the body’s natural rhythm. Getting natural light exposure within the first hour or so of waking is a great way to support optimal hormone balance." It comes after it was revealed that the drink also gives us an extra ‘special boost’ as well as just a caffeine hit. Scientists have claimed that the act of drinking a cup of joe gives the body a lift, making us more alert, which can’t be replicated merely with caffeine.
