A traditional Chinese herbal blend triggers drug-resistant cancer cells “self-destruct” signal, scientists discover. Researchers at Shaoxing University in China tested Huayu Wan, a formula built from two old herbal recipes, on esophageal cancer cells that had become resistant to cisplatin, a common chemotherapy drug. The formula strongly slowed the cells' growth and pushed them into ferroptosis, an iron-driven form of cell death: it stripped away the cells' antioxidant defenses and freed stored iron, letting oxidative damage tear through their membranes. In mice carrying chemo-resistant tumors, it slowed tumor growth, drew more cancer-killing T cells into the tumors, and worked better alongside the immunotherapy drug anti-PD-1 than either treatment alone. Resistance to cisplatin is one of the main reasons esophageal cancer treatment fails, so a way to kill those stubborn cells is worth chasing. This was only cells and mice, though, and nobody knows yet whether it's safe or effective in people, so patients shouldn't swap or add herbs without their oncologist. Studies in humans are being planned, and the team says the formula's iron-driven attack could become a new strategy to pair with existing treatments. source: Zhu, T., Wang, B., Wang, H., Ding, J., Xu, Y., Xu, J., Dong, L., Wang, X., Yu, G., & Li, Z.

Scientists analyzed over 1,000 cases of alleged human reincarnation — and found a very bizarre pattern. For more than 60 years, the University of Virginia's Division of Perceptual Studies has collected cases of young children whose families say they talk about memories of a previous life. A team led by cognitive neuroscientist Saeedeh Sadeghi analyzed 1,678 of these cases in which investigators had identified a specific person the child seemed to describe. In the 1,319 cases with clear dates, the median gap between that person's death and the child's birth was 16 months. But the gap was shorter when the death was sudden, such as an accident, violence or an unexpected medical crisis: about 12 months, compared with 21 months for deaths people saw coming. The pattern held after the team accounted for factors like whether the families already knew each other and what they believed about reincarnation. This is not evidence that reincarnation is real, and the researchers say they are staying agnostic about what's behind it. The cases rely on family accounts and investigators' judgments about which past person matches a child's statements, and sudden deaths tend to be talked about more, which could make them easier to link to a child's stories. The effect is also small, explaining only about 2 to 3 percent of the variation in timing. Still, it's an odd pattern in one of the largest collections of these reports ever studied. source: Sadeghi, S., et al. (2026).

New research is revealing everyday habits are tied to a far higher risk of dementia. Here’s what you need to change, according to the latest science. In a study of about 8,000 people aged 50 to 70, those who regularly slept less than seven hours had a 30% higher risk of dementia. Long-term loneliness can raise risk by around 60%, according to the Alzheimer's Society, while regular exercise is linked to a roughly 28% lower risk. Even air pollution matters: each small rise in fine particle pollution was tied to a 4% higher risk. And in one UK study of 8,623 people, changes in vision predicted dementia up to 12 years before diagnosis. With 153 million people expected to live with dementia worldwide by 2050, prevention is getting serious attention. And sleep, movement, friendship, and cleaner air are worth protecting. source: Howarth, T. (2026). How to cut your dementia risk. BBC Science Focus.

🚨: Daily low-dose aspirin can slash dementia risk by up to 70%, for individuals with a specific genetic profile. For years, medical professionals have debated the brain-boosting benefits of aspirin, with broad clinical trials concluding that a daily regimen does little to stave off cognitive decline for the general population. However, a landmark genetic analysis from Monash University published in Alzheimer's & Dementia has cracked the case wide open by showing that a "one-size-fits-all" approach may have been masking the drug's true potential. By analyzing genetic data from more than 13,500 older adults, researchers discovered that individuals in the top 20 percent of a platelet-related genetic score saw a dramatic 70 percent reduction in dementia risk when taking low-dose aspirin compared to a placebo. While the discovery points to an exciting future for personalized medicine, scientists urge caution before patients run to their local pharmacies. The same genetic traits that make aspirin highly effective at preventing dementia also come with a steep trade-off: the rate of major internal bleeding among the high-benefit group nearly doubled, rising to 4.4 percent for those taking aspirin compared to 2.1 percent on the placebo. Lead author Dr. Peter Fransquet emphasizes that people should not start self-prescribing daily aspirin without consulting a doctor, though the cheap, widely available drug could eventually become a cornerstone of targeted, genetic-based dementia prevention. source: Fransquet, P., et al.

Scientists just discovered the hidden cells that cause men's prostates to enlarge. Almost every man's prostate grows as he ages — almost. But not quite. This is a condition called benign prostatic hyperplasia (BPH) that squeezes the urethra and causes frequent night-time trips to the bathroom and a weak stream. Oddly, it nearly always starts in one area, the 'transition zone' wrapped around the urethra. A Johns Hopkins team led by Rulin Wang and Vasan Yegnasubramanian took healthy prostate tissue from 10 men having surgery for prostate cancer and used single-cell RNA sequencing, which reads which genes each cell has switched on, across nearly 130,000 individual cells. They found a previously unknown kind of basal cell (a supporting cell lining the gland), marked by high activity of a gene called WIF1. These WIF1-positive cells crowd the transition zone, are nearly absent from the rest of the gland, and are more plentiful in enlarged prostate tissue. The cells carry molecular signs of tissue remodelling and of signalling to their neighbours, and some of their genes respond to testosterone, so the team suspects they help reshape the transition zone into the overgrown tissue of BPH. Today, treatment means pills that relax or shrink the prostate, or surgery; a specific culprit cell could become a new drug target. The team also thinks these cells may calm growth signals, which could help explain why prostate cancer rarely starts in this zone. The link is so far an association in human tissue; proving the cells cause the growth is the next step. source: Wang, R., et al. (2026).

Governments are now asking people to keep emergency supplies at home. And France has issued a major warning. “Don't wait for the emergency: prepare now!” a government account for the French region of Normandy said in a social media statement on Tuesday. Countries across the Americas and most of Europe have issued directives for citizens to maintain residential reserves of food, water, and other fundamental resources. The concerns stem from a number of catalysts that could cause (or in some cases, already are causing) systemic disruption — armed conflict, extreme meteorological phenomena, and cyber-incursions. These variables possess the capacity to induce a number of widespread infrastructure failures, making transportation networks impassable and breaking logistical supply chains. It could also result in disruption to municipal water, electrical power grids, electronic commerce systems, and telecommunications. The recommended duration fluctuates by jurisdiction. Canada, France, and the United States specify a 72-hour minimum reserve. Sweden established a one-week minimum. Germany advises a ten-day reserve of nutritional and hydration supplies, while indicating that a three-day reserve offers a functional baseline. Ultimately, residential reserves function as a sustenance buffer that allows one to survive until the arrival of municipal assistance or the reestablishment of operational infrastructure. What should you keep in your emergency caches? Potable water, caloric stores with a long shelf life (peanut butter, canned tuna, walnuts, etc), pharmaceutical supplies, portable illumination, battery-powered radio receivers, and manual mechanical can openers. Though other considerations will be need to taken into account if the home includes an infant, elderly resident, or person with a disability.. That said, these parameters represent standardized contingency protocols, not declarations of imminent catastrophic events. source: Newsweek.

Major U.S. banks are detecting third-party AI agents accessing customer accounts. And they are attempting to take actions that appear to go beyond users’ instructions. According to reports, banks including JPMorgan Chase, Bank of America, Wells Fargo and Morgan Stanley are tightening restrictions on these tools amid concerns about financial security and the risks of giving autonomous AI systems access to sensitive accounts. The challenge is determining whether an AI agent is acting with a customer’s authorization or operating beyond what the customer intended. Some banks are blocking outside AI agents or limiting them to read-only access, which allows information to be viewed without giving the tools control over transactions. As AI assistants become more capable of managing financial tasks, banks face growing pressure to balance convenience with protecting customers’ money and personal information.

A rare form of Ebola with no approved treatment is spreading across Africa, and health leaders warn it won't stay there. Dr. Jean Kaseya, director general of the Africa Centres for Disease Control and Prevention, told the Guardian: "We don't want to see the UK and other countries become the hotspot." The outbreak is caused by Bundibugyo virus, a rarer species of Ebola with no approved treatment. Declared in the Democratic Republic of the Congo in May, it has become the country's largest Ebola outbreak ever, with more than 10,000 confirmed cases, and has spread to Uganda, Kenya and Nigeria, with one imported case in France. For now, the risk outside Africa is rated low: the US CDC says no cases linked to the outbreak have been found in the US. But Kaseya warns that things won’t stay that way — and results from vaccine trials are still three to six months away. Critics argue that the claims are really about money. Of the $3 billion governments pledged, more than $2 billion has not arrived. source: The Guardian. (2026, October 28).

One of the ocean’s most mysterious creatures has reportedly been photographed near the surface, offering a rare glimpse of an animal that usually remains hidden in the deep sea. Photographer Olivia Hickey captured an unusual sight in the water: a large squidlike creature visible just beneath the surface. Encounters like this are exceptionally rare because giant squid normally inhabit deep ocean environments far beyond the reach of ordinary observation. Giant squid belong to the species Architeuthis dux and can reach approximately 12 to 13 meters in total length, including their two extremely long feeding tentacles. Their enormous eyes, which can measure around 27 centimeters across, are among the largest known in the animal kingdom. Scientists believe these eyes help them detect movement and faint light in the darkness of the deep ocean. Despite their enormous size, giant squid remained almost completely unknown to science for centuries. Much of what researchers initially learned came from dead specimens washed ashore or recovered from fishing nets. The first photographs of a living giant squid in its natural deep sea habitat were captured in 2004. Since then, underwater cameras have provided additional glimpses, but direct observations remain uncommon. These animals are also important prey for sperm whales. Scars left by squid suckers on whale skin provide evidence of encounters between two of the ocean’s most remarkable creatures. The exact species and circumstances of this particular sighting have not been independently confirmed. A squid appearing near the surface may also be injured, dying, or experiencing unusual environmental conditions. Even with modern technology, much of the deep ocean remains poorly explored. Animals as large as giant squid can spend nearly their entire lives beyond human observation. Source: Smithsonian Ocean; NOAA Ocean Exploration.

Experts just completed the first-ever complete nerve map of the clitoris. The team says it paves the way for safer pelvic surgeries and a deeper understanding of female anatomy. In a monumental breakthrough for anatomical science, researchers have successfully created the first-ever three-dimensional map of the nerve network inside the clitoris. While the intricate pathways of the penis’s nerves were fully plotted nearly 30 years ago, the clitoris has historically been neglected by the medical community due to persistent cultural taboos and technical challenges. Led by Dr. Ju Young Lee at the Amsterdam University Medical Centers, researchers used state-of-the-art, high-intensity X-ray imaging from a particle accelerator to map the complex, tree-like branching of the dorsal nerve with micrometer-level precision. This revolutionary mapping provides an unprecedented foundation to transition the organ from a historical footnote into a subject of rigorous physiological study. Beyond expanding our understanding of female pleasure and orgasms, this milestone discovery has profound clinical implications. Having an accurate map of these dense sensory pathways can guide surgeons to avoid accidental nerve damage during delicate pelvic procedures, such as gender-affirming surgeries, reconstructive surgeries for survivors of female genital mutilation, and common gynecological operations. By transforming how medical professionals view and treat pelvic anatomy, this study marks a vital first step toward closing the massive gender gap in medical research and ensuring safer, more effective healthcare for women worldwide. source: Lee, J.
