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.

A study has shown that millions of women and girls experience debilitating periods, that even cause mental health problems. A survey of 3,000 women and girls in the UK aged 16 to 40 for the Wellbeing of Women charity found that 86 per cent had had mental health problems, such as depression, anxiety and mood changes, in relation to their period, Meanwhile, of those surveyed, 96 per cent had experienced period pain, with 59 per cent saying their pain was severe. 91 per cent had experienced heavy periods, with 49 per cent saying their bleeding was severe. Even though these are common symptoms in women and girls with gynaecological conditions such as endometriosis, adenomyosis, fibroids and polycystic ovary syndrome, the report found that 51 per cent of respondents felt their healthcare professional had failed to take their problems seriously, and 82 per cent said they needed better access to accurate information on period problems. A further one-third never seek medical help, and more than half say their symptoms are not taken seriously, despite other symptoms including pain, heavy bleeding and irregular cycles. Prof Dame Lesley Regan, the chair of Wellbeing of Women, said: “It’s simply unacceptable that anyone is expected to suffer with period symptoms that disrupt their lives, including taking time off school, work, or their caring responsibilities, all of which may result in avoidable mental health problems. “Periods should not affect women’s lives in this way. If they do, it can be a sign of a gynaecological condition that requires attention and ongoing support – not dismissal.” Wellbeing of Women has launched its “Just a Period” campaign, which Regan said aims to address “the many years of medical bias, neglect and stigma in women’s health”. This includes tips on how to get the most out of seeing your GP and what women should do if they feel they have been dismissed by health professionals. Responding to the findings, Dr Ranee Thakar, the president of the Royal College of Obstetricians and Gynaecologists, said: “All too often women are living with debilitating symptoms, waiting to receive support or treatment for far longer than they should. “Access to high-quality information and support about periods, gynaecological conditions and their symptoms is vital to ensuring that women and girls get the help that they need at the right time.” Caroline Nokes, the Conservative MP and chair of the women and equalities committee, which is conducting an inquiry into reproductive and gynaecological health, said: “There is a terrible phrase: ‘Well, it’s just a period, why are you making a fuss about that? Can’t you just get on with it?’ Yet many women and girls are experiencing horrendous period symptoms and gynaecological conditions. Endometriosis alone affects 1.5 million women in the UK and costs the economy £8.2bn. Now is the time for change.” Anneliese Dodds, the shadow secretary of state for women and equalities, said: “Over the past few years, we have opened up the conversation around the menopause, and now we need to see this change with periods as well.” Sign up to our free Indy100 weekly newsletter Have your say in our news democracy.

Scientists in Israel have created a model of a human embryo from stem cells, without using sperm, eggs or a womb. A team at Israel's Weizmann Institute of Science made the model, which resembles an embryo at day 14, when it acquires internal structures but before it lays down the foundations for body organs, and the work was published in the journal Nature. But the scientists involved said it would take a long time yet to create an embryo from scratch. Team leader Jacob Hanna said the team took stem cells derived from adult human skin cells, as well as others cultured in the lab, then reverted the cells to an early state.They then manipulated them to make a model of an embryo, rather than an actual or synthetic one. "The question is, when does an embryo model become considered an embryo? When that happens, we know the regulations. At the moment we are really, really far off from that point," Hanna said. However, they said the work could open the door to new ways to test the effect of drugs on pregnancies, better understand miscarriages and genetic diseases, and maybe grow transplant tissues and organs. "They are not identical. There are differences from human embryos, but still, this is the first time, if you open an atlas or a textbook, you can say - yeah I can really see the similarity between them," said Hanna. "In about 1 percent of the aggregates we can see that the cells start differentiating correctly, migrating and sorting themselves into the correct structure, and the farthest we could get is day 14 in human embryo development," he said. Their next goal, Hanna said, is to advance to day 21 and also reach a threshold of a 50 per cent success rate. Magdalena Żernicka-Goetz, a professor of development and stem cells at the University of Cambridge, said the study joins six other similar human embryo-like models published from teams around the world this year, including from her lab. "None of these models fully recapitulate natural human development but each adds to ways in which many aspects of human development can now be studied experimentally," she said.
