Want your life to feel longer? Everyone does. And there’s a way to make it happen. Here’s how you can alter your brain to change your perception of time. Research shows that, if the years seem to be speeding up, new places, hobbies, and people may make them feel fuller. It seems simple, but remember how frequently humans get stuck in their routines and habits. Here’s how the research worked: Neuroscientist Martin Wiener and colleagues at George Mason University flashed images at volunteers for between about a third of a second and one second, then asked how long each had stayed on screen. Across four experiments with 21 to 52 people each, the more memorable an image was, the longer people thought they had looked at it, even when every picture was shown for exactly the same time. Images that seemed to last longer were also more likely to be remembered later. Wiener suggests the brain may stretch time to soak up more information when something seems important. The lab study measured small shifts over fractions of a second, so applying it to whole years is an extrapolation, but it fits a pattern you may know: routine weeks blur together, while a week somewhere new feels longer looking back. source: Ma, A.

There’s a natural way to protect your teeth. One swish of pure cranberry juice slows plaque, new study shows. Researchers at the University of Illinois Chicago, led by pediatric dentist Christine Wu, asked 14 children and 8 adults to skip brushing for 24 hours, then swish and swallow one of three drinks on different days: unsweetened 100% cranberry juice, a sweetened cranberry cocktail with 27% juice, or water. They swabbed plaque, the sticky film of bacteria on teeth, before the drink and again 30 minutes later. Pure cranberry juice cut bacterial growth in plaque by 44% and significantly reduced the acid plaque makes, which is what wears holes in teeth. The sweetened cocktail didn't make a significant difference, likely because it has less of the plant compounds called proanthocyanidins and plenty of sugar. It's a small, short-term study that measured plaque activity rather than actual cavities, and juice is acidic, so it isn't a replacement for brushing. But it points to a cheap, natural helper for oral health. source: Wu, C. D., et al. (2026).

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.

A surgeon transplanted a piece of spinal cord from a brain-dead donor into a paralyzed patient for the first time. Xiaoping Ren, a Chinese surgeon at the Second Affiliated Hospital of Guangxi University of Chinese Medicine, told New Scientist that he and Russian colleagues performed the operation at Moscow's Sklifosovsky Institute for Emergency Medicine. The patient is an adult with a complete spinal cord injury from three years ago. According to Ren, the team removed the damaged section and joined in a segment of spinal cord from a brain-dead donor, using microsurgery and a chemical called polyethylene glycol meant to help nerve fibers fuse. Moscow's mayor said the surgery took 12 hours and that the patient "is currently feeling well." No movement or sensation gains have been reported. Ren is best known for promoting a human head transplant with Italian surgeon Sergio Canavero, which never happened, and no clinical data on this surgery have been published or reviewed by other scientists. Experts have questioned the animal studies behind the technique, which mostly used freshly cut cords in a handful of animals rather than old injuries, and warned of serious infection and surgical risks. Better-tested approaches, such as brain-spine implants and electrical stimulation, have already helped some people with long-term injuries regain movement. Until the results are published, this is a claim, not a breakthrough. source: McRae, M. (2026, October 21). World-first spinal cord transplant claim raises questions we can't yet answer. New Atlas.

🚨 This could be the end of Type 2 diabetes. Researchers at ETH Zurich led by Martin Fussenegger built a small wireless implant that uses electricity to break down extra sugar in the blood. It switches off when levels are normal — and means people won’t need diabetes drugs anymore. Inside is a catalyst made of graphite felt coated with tiny gold and platinum particles, with no living cells or drugs. A glucose sensor worn on the arm watches sugar levels. When they climb after a meal, it signals a phone or smartwatch, which switches on the implant. The catalyst then turns glucose into gluconate, a harmless compound the body flushes out in urine, and the system shuts off once sugar is back on target. In diabetic mice, the device kept blood sugar under tight control for six weeks, the animals lost weight, and it caused no sign of tissue damage. Because less sugar ends up stored as fat, the team sees it as a possible tool for both type 2 diabetes and obesity, without daily pills or injections. So far it has only been tested in mice, and human trials are still ahead. source: Maity, D., et al. (2026). Wireless electrocatalytic closed-loop system for drug-free management of diabesity.

A new drug only switches on inside cancer cells and destroys them — leaving healthy cells entirely intact This means fewer of the side effects that make treatment so brutal. Many cancer cells give off unusually high amounts of carbon monoxide, a byproduct of their stressed metabolism, while healthy cells make very little. A team at RIKEN in Japan led by chemist Katsunori Tanaka turned that difference into a trap. They tucked a palladium catalyst, a metal compound that speeds up chemical reactions, inside albumin, a common blood protein that shields it on the way into cells. Once inside, the catalyst uses the cell's own carbon monoxide to assemble phenanthridinone, a compound that kills cells. The drug formed in liver, cervical, breast and lung cancer cells, but not in healthy cells. A modified version made an even more toxic compound that damaged liver cancer cells from within. Because the drug is only built where the gas is, the idea could one day target tumors while sparing healthy tissue, which is what causes many chemotherapy side effects. So far this has only been shown in cells in a dish, and animal tests are next. source: Kawai, M., et al. (2026). Harnessing endogenous carbon monoxide for cancer-selective drug synthesis.

An new drug kills fat cells instead of shrinking them, offering a radical new approach to treating obesity. Traditional weight loss strategies—including diet, exercise, and popular GLP-1 medications—primarily function by shrinking fat cells or curbing appetite, leaving the underlying cell structure intact. However, preliminary clinical research on an experimental injectable compound known as CBL-514 reveals a transformative mechanism: it triggers targeted apoptosis, or programmed cell death, causing fat cells to permanently self-destruct. Early human trials demonstrated an average 12% reduction in deep abdominal visceral fat within just four weeks of treatment. By directly dismantling the cellular architecture of fat tissue, this therapeutic approach could target stubborn areas that typically resist standard weight management routines. Beyond targeted fat reduction, destroying visceral fat cells directly addresses the root driver of severe cardiovascular and metabolic disorders, including type 2 diabetes and hypertension. Researchers also suggest that permanently eliminating these cells could solve one of the biggest hurdles in modern weight management: the rapid weight regain that frequently occurs after patients discontinue appetite-suppressing medications. While further large-scale clinical trials are required to confirm its long-term safety profile and efficacy, this novel cellular-destruction strategy marks a major paradigm shift from temporary weight control toward potential long-term metabolic rehabilitation. source: European Association for the Study of Diabetes.

A thin cap of water on the tau protein decides when it clumps into the tangles linked to Alzheimer's, and blocking that spot stopped it. Tau normally helps hold up the internal skeleton of nerve cells. In Alzheimer's and related diseases, it misfolds and stacks into long fibers called fibrils, and one misfolded tau can push others to misfold too. Researchers at Northwestern University and UC Santa Barbara studied a short, mutated piece of tau using lab experiments and computer models. They found a "hotspot" on its surface that repels water but is still covered by a thin cap of water molecules. When two of these hotspots meet, the water is released and the proteins lock together. When the team blocked the hotspot with a chemical tag, the fibrils stopped growing. That makes the hotspot a possible target for future drugs aimed at stopping tau tangles from spreading between brain cells. But this is very early work: it was done on a 19-amino-acid fragment of the protein, not in living brains, and no drug exists yet. Scientists are also still debating how much tau tangles drive Alzheimer's rather than result from it. source: Han, S., et al. (2026). Proceedings of the National Academy of Sciences.

Psychopathic corporate leaders really exist. And scientists just identified who set the standard. The tricks toxic bosses use today were used to devastating effect by a company man nearly 400 years ago. In June 1629, the Batavia, a ship of the Dutch East India Company (often called the world's first multinational corporation), struck a reef off Western Australia. The captain and senior officers sailed off for help, leaving a company merchant named Jeronimus Cornelisz as the top official among roughly 200 stranded survivors. He swapped the islands' council for loyalists who swore personal oaths to him, hoarded the supplies and treasure, sent rivals to other islands, and had about 100 men, women, and children killed — claiming it saved food and water. Dr Clive Boddy of Anglia Ruskin University scored Cornelisz against a modern corporate psychopathy framework and found he showed all 10 core traits, from superficial charm and deceit to zero remorse and dodging blame. Boddy calls the disaster "effectively a natural experiment in leadership.” With the rules gone, one man's character decided who lived. His playbook of stacking committees with loyalists, dividing opponents and ruling through fear still shows up in workplaces today, and research links psychopathic leaders to bullying, burnout, staff turnover and company collapse. Boddy argues firms should weigh character and ethics far more heavily when picking senior leaders. It's a diagnosis of a man dead for nearly 400 years, built from historical records. Cornelisz himself was captured, tried and hanged in 1629. source: Boddy, C. R. (2026). Asia bound: Shareholder capitalism, corporate psychopathy and psychopathic leadership.

In one trial, a cholesterol-lowering diet cut "bad" cholesterol almost as much as a statin. Dr Riyaz Patel, an NHS doctor and academic cardiologist at University College London, told BBC Science Focus that "the very best thing to improve cholesterol levels is to change our diets." His top picks: oats, whose soluble fibre helps lower cholesterol; plant sterols and stanols, found in fortified yoghurts and spreads, which he calls "probably the best non-pharmaceutical way of lowering your cholesterol, typically by about 10 per cent"; and cutting back on saturated fat, which interferes with the liver's ability to clear LDL, the "bad" cholesterol, from your blood. High LDL clogs arteries and drives heart attacks and strokes, and diet can do more than many people expect. In a 2003 trial in JAMA, a "portfolio" diet combining sterols, soluble fibre, soy protein and nuts cut LDL by 28.6% in a month, close to the 30.9% seen with a low-dose statin, although that trial was small and tightly controlled. Results vary, and some people see little change. That said, if your doctor has put you on a statin, don't stop it without talking to them. source: Willmoth, H.

Smokers have a 30% lower risk of Parkinson's. A new study finally found the cause. Researchers at the University of Oxford followed 512,701 adults in China for about 12 years and measured the carbon monoxide (CO) in their breath at the start. CO is the same gas found in cigarette smoke, but your body also makes tiny amounts of it, where it works as a signaling molecule. Over the follow-up, 1,131 people developed Parkinson's. Regular smokers had about a 30% lower risk, as earlier studies found. The surprise came from people who had never smoked: those with higher CO in their breath were roughly a third less likely to develop Parkinson's than those with the lowest levels. The link didn't show up for other brain diseases. Let's be very clear: smoking is never a way to prevent Parkinson's. It causes cancer, heart disease and stroke, and its harms far outweigh anything else. What this study offers is a clue. If low levels of CO really calm inflammation and cell stress in the brain, as lab and animal studies hint, scientists could one day design safe, controlled CO treatments. A first small trial of a low-dose CO drug in Parkinson's has already started at Harvard. This is an observational study, so it shows a link, not proof that CO protects the brain. source: Bueno Lopez, C., Iona, A., Turnbull, I., et al. (2026).

A tiny new implant injected via a standard needle wirelessly regulates nerve signals — ending chronic pain without surgery, wires, or internal batteries. Developed by researchers at NYU Abu Dhabi and Cleveland Clinic Abu Dhabi, the miniature device—dubbed SEED (Stimulating Electrode for Electroceutical Delivery)—can be delivered through a standard medical needle. Positioned precisely near a targeted nerve using routine ultrasound or CT imaging, the seed-sized implant receives power wirelessly from a compact external transmitter. Once activated, it delivers soft electrical impulses that disrupt malfunctioning pain signals before they reach the brain, bypassing the need for invasive surgical procedures or internal battery packs. Traditional spinal stimulators require complex surgeries and carry risks of hardware infection, while oral painkillers often bring severe side effects and addiction risks. By offering a customizable, injectable alternative, this wireless electroceutical technology represents a major leap in non-surgical therapy for chronic pain, movement disorders, and paralysis. While currently in preclinical testing, it paves the way toward safer, on-demand relief that can be adjusted in real time by clinicians and patients alike. source: Ramadi, K., et al. (2026).

A personalized mRNA vaccine cut the risk of melanoma coming back or death by 42% in a major trial. The trial, called INTerpath-001, enrolled 1,137 adults whose stage 2 to 4 melanoma had been surgically removed but who were at high risk of it coming back. All of them received pembrolizumab (Keytruda), a drug that helps the immune system attack cancer. About two-thirds also got the vaccine, which is made for each patient by reading the genetic code of their tumor and encoding up to 34 of its unique mutations in mRNA. That trains the immune system to hunt down any cancer cells left behind. After about two years, 82.2% of the vaccine group were still cancer-free, compared with 70.0% of those on the immunotherapy drug alone. Melanoma is the deadliest form of skin cancer, and this is the first time a personalized cancer vaccine has shown a clear benefit in a large, late-stage trial. The vaccine isn't approved yet, and it's too early to know if it helps people live longer, since survival data are still coming in. Side effects were mostly short-lived, like fever, sore arms and fatigue. source: Long, G. V., et al. (2026).

Low-dose aspirin slashed dementia risk by 70% in certain people, study shows. Researchers at Monash University in Australia went back to the ASPREE trial, a large study in which older adults took either a daily low-dose aspirin or a dummy pill (placebo). They analyzed the genetic data of more than 13,500 participants and gave each person a "polygenic score", a combined measure of many small gene variants, linked to how many platelets their blood makes. Platelets are the tiny cells that help blood clot. In the 20% of people with the highest platelet scores, just 1% of those on aspirin developed dementia, compared with 3.3% of those on placebo, about 70% lower risk. Earlier trials found aspirin didn't prevent dementia when everyone was considered together, so this points to a hidden group who might benefit, and to platelet biology as a new lead in dementia research. The signal wasn't tied to known Alzheimer's risk genes. But the same high-score group also had more major bleeding on aspirin, 4.4% vs 2.1% on placebo. This is a subgroup finding that still needs confirming in a dedicated trial. Do not start taking aspirin to prevent dementia on your own: daily aspirin can cause serious bleeding, so talk to your doctor first. source: Fransquet, P. D., Yu, C., Tran, C., Hussain, S.

"The cat is out of the bag and it's only going to keep spreading.” Dengue is spreading in Florida, and the mosquitoes that carry it now live as far north as Virginia. As a result, the CDC has activated a Level 3 emergency response for dengue in Florida, its eighth emergency activation of 2026. Florida has logged 425 locally acquired dengue cases this year, meaning people caught the virus from mosquitoes in Florida rather than while traveling, as of the state's weekly report through Oct. 17. Most are around Tampa: Hillsborough County has 346 and neighboring Pinellas has 51, with cases now in 11 counties. That is more than double Florida's previous record of just under 200 local cases in 2023, and MedPage Today reports it is the largest outbreak in the continental US since 1935. CDC experts say most cases involve DENV-2, one of dengue's four types, and 47% of reported patients needed hospital care. One death, an elderly Tampa woman, was reported in September. Dengue, sometimes called breakbone fever, spreads through the bite of Aedes mosquitoes. Most infections cause no symptoms, so experts say the official count is only the tip of the iceberg. A second infection with a different type raises the risk of severe dengue, which can cause internal bleeding and shock. There is no dengue vaccine licensed for general use in the US, so the best protection is repellent, long sleeves and getting rid of standing water around your home. Hillsborough and Pinellas counties have extended their states of emergency through Oct. 29.

🚨 A patient has been given a infusion designed to rewrite a faulty gene directly inside their body. Prime Medicine announced on October 5 that the first patient has been dosed in its trial of PM577a, an experimental one-time therapy for Wilson disease. People with this inherited disorder can't clear copper properly, so it builds up in the liver and can damage the brain, kidneys and eyes. The treatment travels through the bloodstream in tiny fat bubbles called lipid nanoparticles and uses prime editing, a find-and-replace tool for DNA, to correct the most common Wilson disease mutation in North America and Europe without cutting through both strands of DNA the way classic CRISPR does. Today, people with Wilson disease take medication every day for life, and the only cure is a liver transplant. A single infusion that corrects the gene itself could change that. Genes have been edited inside the body before with other tools, and this is an early safety trial, with the company's first results expected in 2027. source: Prime Medicine. (2026, October 5).

🚨 Cancer deaths linked to alcohol consumption have more than doubled in the U.S. Scientists warn that even light drinking carries severe health risks. A landmark study published in 'The Lancet Regional Health – Americas' reveals a stark rise in alcohol-attributable cancer deaths, which soared from 11,361 in 1990 to 23,126 in 2023. Researchers from the Sylvester Comprehensive Cancer Center at the University of Miami Miller School of Medicine found that while overall cancer mortality has declined, the proportion of cancer deaths linked to alcohol has dramatically increased. The study highlights that the deadly impact of alcohol is not limited to liver disease; it plays a critical role in breast, colorectal, esophageal, and head and neck cancers. Alarmingly, older men and adults over 55 experienced the heaviest burden, though the rise was observed across nearly all demographic groups. Despite the scientific consensus classifying alcohol as a Group 1 carcinogen alongside tobacco and asbestos, public awareness of this connection remains critically low. Health experts warn that there is no truly 'safe' level of consumption, as even one standard drink per day can elevate cancer risks. To combat this rising public health crisis, scientists and advocates are calling for stronger preventative strategies, including clearer cancer warning labels on alcoholic beverages, public education campaigns, and proactive screening by healthcare providers. source: Jani, C., et al.

Research shows the genetic shifts that granted humans intelligence also paved the way for Autism. A groundbreaking study published in Molecular Biology and Evolution suggests that the very genetic shifts that granted humans superior intelligence also paved the way for neurodiversity. By comparing brain RNA across six mammalian species, researchers discovered that the neurons responsible for high-order functions—such as reasoning, complex thinking, and language—evolved significantly faster in humans than in other primates. This rapid transformation occurred specifically in the neocortex, where the genes driving these cognitive leaps are the same ones linked to autism and schizophrenia. The findings indicate that the biological 'price' for our unique mental capabilities was an increased sensitivity to these neurodevelopmental variations. This evolutionary trade-off mirrors other survival adaptations, such as the genetic link between malaria resistance and sickle cell anemia. Scientists believe these specific genetic mutations conferred a massive fitness benefit to our ancestors, enabling the development of complex societies despite increasing the likelihood of certain disorders. According to the research team at Stanford University, the human species might not exist in its current form without the existence of these traits. Rather than being accidental errors, these genetic markers are fundamental to the architecture of the human mind, illustrating that neurodiversity is inextricably linked to the rise of human genius. source: Starr, A., et al.

Oral sex has overtaken smoking as the primary driver of throat cancer. In a significant shift in oncology, the human papillomavirus (HPV) has replaced tobacco and alcohol as the leading cause of oropharyngeal cancer. This specific strain, most commonly HPV-16, targets the tonsils and the back of the throat, where it can persist and replicate. While the body clears most HPV infections, persistent cases can trigger cellular changes that evolve into malignancy over time. Currently, HPV is responsible for approximately 70% to 85% of all throat cancer diagnoses in several Western nations, marking a public health turning point. Research indicates that the risk of contracting this cancer is directly linked to sexual history, as the virus is primarily transmitted through oral sex. Studies show that a higher number of lifetime sexual partners correlates with a greater risk of infection, with men being significantly more susceptible to oral HPV than women. Public health experts emphasize that HPV vaccination remains the most effective preventive measure, particularly when administered to young adults, alongside increased awareness of the risks associated with oral transmission. source: The Conversation.
