Octopuses' 8 Arms Snoop on the Microbial World
When octopuses extend their eight arms into hidden nooks and crannies in search of a meal, they are not just feeling around in the dark for their food. They are tasting their prey, and with even more sensory sophistication than scientists had already imagined. Researchers reported on Tuesday in the journal Cell that octopus arms are fine-tuned to 'eavesdrop into the microbial world,' detecting microbiomes on the surfaces around them and deriving information from them, said Rebecka Sepela, a molecular biologist at Harvard and an author of the new study. Where octopus eyes cannot see, their arms can go to identify prey and make sense of their surroundings. Scientists knew that those eight arms (not tentacles) sense whether their eggs are healthy or need to be pruned. And the hundreds of suckers on each arm have over 10,000 chemotactile sensory receptors each, working with 500 million neurons to pick up that information and relay it throughout the nervous system. Yet, what exactly the octopus is tasting by probing and prodding — and how its arms can distinguish, say, a rock from an egg, a healthy egg in its clutch from a sick one or a crab that's safe to eat from a rotting, toxic one — has long baffled scientists. What about the surfaces are they perceiving? For Dr. Sepela, this question was heightened when her team discovered 26 receptors along the octopuses' arms that didn't have a known function. She supposed those receptors were tuned only to molecules found on surfaces, rather than those diffused in water. So she and her colleagues collected swaths of molecules coating healthy and unhealthy crabs and octopus eggs. They grew and cultured the microbes from those surfaces in the lab, then tested 300 microbial strains, one by one, on two of those 26 receptors. Want all of The Times? Subscribe.

Could faecal transplants cause long-term health problems?
Keeping a healthy mix of friendly microbes in the gut – known as eubiosis – is crucial for good health. When that delicate balance is thrown off – often by antibiotics, diet or illness – the result can be a range of issues, from digestive problems to more serious conditions like Crohn's disease, ulcerative colitis, and even neurological and metabolic disorders. One increasingly popular way to try to restore gut health is through faecal microbiota transplantation. This involves taking stool from a healthy person, isolating the beneficial microbes and putting them in a capsule (jokingly referred to as 'crapsules' or 'poo pills'). The hope is that the beneficial microbes in the pill will establish themselves in the patient's gut, thereby improving microbial diversity and function. Faecal transplants have been used to treat a wide array of conditions, including irritable bowel syndrome, Parkinson's disease, obesity and Type 2 diabetes. Although generally viewed as safe and effective, a new international study published in the journal Cell has raised some concerns. The scientists found that when the donor's microbes do not properly match the recipient's gut environment – a situation they describe as a 'mismatch' – the treatment can disrupt the body's metabolic and immune systems, possibly with long-lasting consequences.

Sign up to our daily newsletter to receive all The Conversation UK's latest coverage of news and research, from politics and business to the arts and sciences. The term 'mismatch' comes from the world of organ transplants, where the recipient's body rejects the donor organ. In this case, the problem is that microbes from the donor's large intestine may not be suitable for other parts of the recipient's gut, especially the small intestine, where the microbial makeup is very different. To test this, researchers gave antibiotics to mice to disturb their natural gut microbes, then treated them with faecal transplants. They also tried transplanting microbes specifically from different parts of the small intestine. The mice were monitored for one to three months to track changes. They found that faecal transplants often led to regional mismatches – the wrong microbes ending up in the wrong place. This altered the mix and behaviour of the gut microbes in unexpected ways, disrupting energy balance and other functions. Biopsies from the gut and liver showed significant, lasting changes in how certain genes – particularly those linked to metabolism and immunity – were being expressed. The study did not specify exactly what kind of health issues might result from these genetic shifts. But the researchers are urging doctors to take greater care when using faecal transplants, particularly when it comes to dose, timing and possible side-effects. There may, however, be a better way forward. A newer method known as the 'omni microbial approach' involves transferring microbes from all parts of the intestine, not just the colon. This could help recreate a more balanced and natural gut environment, avoiding the local mismatches seen in standard faecal transplants. There is also growing interest in techniques that aim to 'terraform' the gut: deliberately reshaping specific regions with carefully selected microbes to restore normal function. This new research has certainly sparked debate around the safety of faecal transplants. But with alternative approaches already being developed, there is real hope that the benefits of gut-based treatments can still be delivered, without the risks.

Men are losing the Y chromosome: What it means for men's health and aging
For years, we've been taught that men have one X and one Y chromosome, with the Y carrying the vital gene that initiates male development. But now, scientists are sounding the alarm: the Y chromosome is slowly disappearing. Unlike the X, which holds hundreds of genes, the Y has lost most of its genetic content over millions of years. Some researchers predict it could vanish entirely in about 11 million years. While that may seem far away, evidence suggests the effects of Y chromosome loss are already showing up in men today — especially in how they age and stay healthy. The complete study is published in the journal Cell . How Y chromosome is fading in men Compared to its counterpart, the X chromosome, which carries around 900 genes, the Y is tiny and holds just about 55 genes. Genetic studies show that over millions of years, the Y chromosome has been steadily losing genes. Researchers estimate that if this trend continues, the Y could disappear completely in roughly 11 million years. That might sound far off, but clues from both animals and humans suggest the effects may already be happening — and they're not just theoretical. Men already losing Y chromosomes in their cells Long before the chromosome disappears from the species, many men are already starting to lose it in some of their cells. Starting around age 50, some bone marrow cells begin to misplace the Y chromosome during cell division. These Y-less cells multiply, especially in the blood. By the time a man reaches 80, about 4 in 10 have a significant amount of blood cells missing the Y — a condition known as "mosaic loss of Y," or LOY. A long-term study in Sweden tracked over 1,100 older men and found that those with LOY had higher risks of cancer, heart disease, and Alzheimer's, and died an average of 5.5 years earlier than those without the condition. Why losing the Y matters to the immune system One of the genes on the Y chromosome, called UTY, helps regulate the immune system. When it's gone, certain immune cells stop working the way they should. Some start producing more scar tissue, while others become weaker and less able to fight cancer. In lab tests, mice without the Y chromosome developed faster-growing tumors and more heart damage. In humans, tumors that lack the Y — especially in the bladder — tend to be more dangerous. But there's a twist: these same tumors also respond better to a specific cancer treatment called checkpoint inhibitors. It's a reminder that biology often works in unexpected ways. Results of the research done on rodents Some rodent species, like the Japanese spiny rat and certain mole voles, have already lost their Y chromosomes completely — and yet, they still manage to produce male offspring. In 2022, scientists discovered that a copy of DNA near a gene called SOX9 can take over the job of turning on male development, even without the usual Y-linked trigger. This finding suggests that evolution can find workarounds. If the Y disappears in humans one day, it's possible that a new system could emerge to take its place. What can men do to prevent the Y chromosome loss While we can't stop evolution, we can slow down the loss of the Y chromosome in our own bodies. Things like smoking, air pollution, and exposure to toxic chemicals speed up DNA damage, including Y chromosome loss. Quitting smoking, avoiding environmental toxins, and leading a healthy lifestyle — with regular exercise, nutritious food, and good sleep — may help preserve more Y-bearing cells. Some drugs used to treat lung disease are being tested to see if they can prevent the heart damage linked to Y loss. And as medical tests become more advanced and affordable, men might soon be able to get a 'Y-loss score' during regular checkups, much like cholesterol levels. A story of evolution and urgency The shrinking Y chromosome sits at a strange crossroads between slow evolutionary change and urgent medical challenges. On one hand, nature seems to have a backup plan for the far future. On the other hand, individual men today are already feeling the consequences in their health. It's a perfect example of how evolution and medicine don't always share the same timeline. Evolution cares about passing on genes, not about living into your 80s. But for doctors and patients, the immediate risks matter more. Even though the idea of the Y chromosome disappearing sounds alarming, there's no need for panic. Evolution is adaptable, and medical science is catching up fast. For now, the most practical advice is simple: stay healthy, avoid harmful chemicals, and pay attention to new research.
