Anti-aging drug cocktail boosts mouse lifespan by 30 percent, offers hope for human longevity
Max Planck Institute for Biology of Ageing
in Germany has revealed that a combination of two existing drugs—rapamycin and trametinib—can extend the lifespan of mice by up to 30 percent. Not only did the mice live significantly longer, but they also remained healthier in old age, showing reduced inflammation, delayed tumour growth, and better overall physical function. This discovery could mark a major step forward in the pursuit of anti-ageing treatments for humans, offering hope that ageing-related decline can be slowed or even partially reversed in the future.
What is the drug combination that boosts the lifespan of mice
Rapamycin and trametinib
are both known drugs primarily used in cancer treatment. Rapamycin has been used to prevent organ rejection in transplant patients and has shown life-extending properties in animals. Trametinib, while less studied in larger animals, previously extended the lifespan of fruit flies. Scientists administered these drugs individually and in combination to hundreds of mice from the age of six months, then tracked their health and longevity. The combination therapy produced the most remarkable effects, with median lifespan increases of 34.9 percent in female mice and 27.4 percent in males.

Importantly, the mice receiving the combination therapy did not merely live longer—they lived better. The treated animals experienced fewer age-related conditions such as liver and spleen tumours, and displayed significantly reduced inflammation in the brain, kidneys, muscles and spleen. They also retained more mobility and exhibited improved heart function. These results suggest that the treatment helps maintain a higher quality of life throughout old age, a key goal in the field of
longevity research
.
Why this matters for humans
Although these findings are based on animal models, they carry significant implications for human health. Both rapamycin and trametinib are already approved for medical use in humans in the United States and European Union, which could accelerate the path toward clinical trials for anti-ageing purposes. The fact that the combination targets different points in the same cellular pathway—the Ras/Insulin/TOR network—suggests a sophisticated synergy that enhances the benefits of each drug while limiting side effects. This gives scientists a strong foundation to begin evaluating their effectiveness in human ageing.
Caution and next steps
While the results are promising, researchers urge caution before assuming similar effects will be seen in people. Human biology is far more complex, and long-term use of these drugs could carry risks that are not evident in animal studies. Geneticist Linda Partridge, co-senior author of the study, emphasised that the goal is not necessarily to extend human lifespan dramatically, but to improve the quality of later life. Further studies and eventual human trials will be necessary to determine who might benefit and how best to apply the treatment.
The future of anti-ageing research
This study adds to a growing body of evidence suggesting that ageing can be manipulated through targeted medical interventions. As scientific understanding of cellular ageing deepens, the potential for developing treatments that slow or modify the ageing process becomes more tangible. With further research, the dream of living not just longer, but healthier lives into old age may one day become a reality for many.

How oil pulling prevents gum diseases and cavities naturally: Know its benefits, risks, and step-by-step guide
Oil pulling is an ancient oral hygiene practice rooted in Ayurvedic medicine that's making a strong comeback today. This natural method involves swishing edible oil, typically coconut or sesame oil , in your mouth for 10 to 20 minutes to help draw out toxins, bacteria, and debris. The process is believed to promote healthier teeth and gums, reduce bad breath, and support overall oral health. Unlike many commercial mouthwashes, oil pulling is chemical-free and gentle on the mouth. With both traditional use and emerging scientific studies backing its benefits, more people are turning to oil pulling as a simple and effective daily routine. Understanding oil pulling and its health benefits Oil pulling is the practice of swishing oil in your mouth, typically sesame or coconut oil, for about 10 to 20 minutes, then spitting it out. This technique has been used for centuries in Ayurveda, a traditional Indian system of medicine. The idea behind oil pulling is that the oil "pulls" out toxins, bacteria, and debris from your mouth, helping to cleanse the oral cavity and support better oral health. Here are the top reasons people are adding this practice to their daily routine: 1. Reduces cavity-causing bacteria Oil pulling helps reduce the presence of Streptococcus mutans, a bacteria that contributes to tooth decay. Fewer bacteria mean a lower risk of cavities and tooth damage. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Your Finger Shape Says a Lot About Your Personality, Read Now Tips and Tricks Undo 2. Improves gum health Studies show that regular oil pulling can reduce gum inflammation and bleeding, supporting healthier gums and lowering the risk of gingivitis. 3. Decreases plaque buildup Swishing oil daily helps reduce plaque accumulation on the teeth. Less plaque means fewer chances for tartar formation and periodontal disease. 4. Fights bad breath Oil pulling removes odour-causing bacteria, helping to eliminate bad breath naturally without using strong chemical mouthwashes. 5. Natural and chemical-free Unlike many commercial oral products, oil pulling uses pure, edible oils. It's free from synthetic additives, alcohol, and harsh chemicals, making it ideal for natural oral care routines. Potential risks and side effects of oil pulling While oil pulling is generally safe, here are a few things to watch out for: Allergic reactions: Some people may be allergic to coconut oil. If you've never used it before, do a patch test or consult your doctor before trying oil pulling. Jaw soreness: Swishing for 20 minutes may cause jaw fatigue or soreness, especially for beginners. Start with shorter sessions and work your way up. Interactions with oral products: Coconut oil may interact with certain oral products like mouthwash or medicated toothpaste. Be sure to space out your routine and consult your dentist if unsure. How to do oil pulling with coconut oil: Step-by-step Choose high-quality oil: Use organic, cold-pressed, virgin coconut oil to ensure you're using the purest and most effective form. Take a tablespoon: Scoop 1 tablespoon of coconut oil and place it in your mouth. You can start with a smaller amount if you're a beginner. Swish gently for 15–20 minutes: Move the oil around your mouth gently. Don't gargle or swallow it. Try to reach all corners of your mouth. Do not swallow the oil: The oil absorbs toxins and bacteria, so swallowing it can be harmful. Spit it out & rinse: Spit the used oil into a trash can (not the sink—it can clog pipes), and rinse your mouth thoroughly with warm water. Brush your teeth normally: Finish your oral hygiene routine by brushing with fluoride toothpaste. Also read | 12 natural remedies to cure mouth ulcers

Can just one workout reduce cancer risk? Research says it may—by as much as 30%
Imagine this: a single exercise session might actually lower cancer cell growth by almost a third. Sounds pretty awesome, right? A new cancer research study on exercise by scientists from the Edith Cowan University found that just one workout can seriously slow down how fast cancer cells grow. Researchers dug into how physical activity affects cancer risk at the cellular level and discovered that it triggers some powerful changes, like boosting the immune system and releasing substances that can help keep cancer cells in check. The findings of the study have been published in the journal Breast Cancer Research and Treatment. The cool part? You don't need to be a gym fanatic or do marathon training. Even a single bout of moderate exercise for cancer prevention seems to kick-start this anti-cancer effect. "Breast cancer is the leading cause of cancer-related death in women, highlighting the need for strategies to mitigate recurrence and mortality. We examined the effects of a single bout of resistance training (RT) versus high-intensity interval training (HIIT) on anti-cancer myokines and in vitro cancer cell suppression," the researchers have said. "A single bout of RT or HIIT can increase levels of anti-cancer myokines and reduce the growth of MDA-MB-231 cells in vitro in survivors of breast cancer, potentially contributing to a lower risk of recurrence. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Libas Purple Days Sale Libas Undo This highlights the importance of exercise as a treatment with promising anti-cancer effects," they have concluded. Examples of resistance training and HIIT workouts Resistance training (also called strength or weight training) is all about building muscle and making your body stronger. You can use dumbbells, resistance bands, kettlebells, or even just your body weight. Think squats, push-ups, lunges, planks, and bicep curls. It's not just for bodybuilders—it helps boost metabolism, protect your joints, and even reduce your risk of certain cancers. Then there's HIIT (High-Intensity Interval Training)—basically short bursts of hard work followed by quick rests. A classic example? 30 seconds of jumping jacks, 15 seconds rest, then 30 seconds of burpees. You repeat this pattern for 15–30 minutes. Other moves include mountain climbers, high knees, jump squats, or sprint intervals on a bike or treadmill. How exercise helps cut your cancer risk (and it's easier than you think) When you think about ways to reduce your cancer risk, your mind probably goes to eating healthy, quitting smoking, or avoiding too much sun. And while those things absolutely matter, there's another powerful habit that often gets overlooked: exercise. Yep, just moving your body regularly can make a real difference when it comes to preventing cancer. And no—you don't need to be running marathons or spending hours at the gym to see the benefits. So how does it work? Well, exercise helps in a few ways. First, it boosts your immune system, which plays a huge role in fighting off abnormal cells that can turn cancerous. It also reduces inflammation in the body—a key factor in cancer development. Plus, staying active helps control body weight and hormones like estrogen and insulin, both of which are linked to certain cancers when they're out of balance. The best part? You don't have to do a ton to make an impact. Research shows that just 30 minutes of exercise a day, five times a week, can be enough to start protecting your health. Even breaking it into smaller chunks—like 10-minute walks after meals—still counts. And here's something wild: a recent study even found that a single workout can slow the growth of cancer cells by up to 30%. So yes, even one session can make a difference. The takeaway? Exercise isn't just about looking fit or losing weight. It's one of the most accessible and natural tools we have to protect ourselves from serious diseases like cancer. No pills, no fancy gadgets—just your body in motion. So whether you're walking the dog, biking through the park, or just dancing around your kitchen, you're doing something great for your long-term health. Keep moving—you've got more power than you think.
