Scientists say young blood and bone marrow cells can reverse aging in human skin cells
bone marrow cells
and injected into older skin cells, producing rejuvenating effects. This process is called heterochronic parabiosis, which is transferring blood from a younger animal to an older one. Earlier tests on rodents showed reduced signs of aging.
So far, all tests have been done in lab dishes, and scientists say they need to do more research to understand how it really works. The anti-aging market makes a lot of money by selling creams, serums, light treatments, and vampire facials that promise younger-looking skin—but most of them don't really work, as reported by Popular Mechanics.
Vampire facials and bone marrow
Vampire facials drain blood from a person and claim to act as anti-aging treatment, but most likely do nothing.
Beiersdorf researchers
claim that combining young blood serum with bone marrow cells caused visible rejuvenation in skin cultures in the lab. They observed that serum alone had no effect on older skin cells—proving that bone marrow cells are necessary.

This method does not require harming humans, unlike the macabre legend of Countess Elizabeth Bathory, who supposedly bathed in virgins' blood to stay young. Experiments on older mice and rats using injections of young blood and bone marrow cells from younger animals had positive results, showing improved aging signs, as per the report by Popular Mechanics.

Researchers explained: 'With longer life expectancy, it is important to study aging, promote healthy aging, and extend disease-free lifespan. Skin is the largest organ and shows early aging, reflecting overall health'. To test on humans, Beiersdorf injected human skin cell cultures with: Serum with bone marrow cells and Serum without bone marrow cells.
Stem cells and skin rejuvenation
Bone marrow cells are important because they have stem cells that can become other cells and make more of themselves. These stem cells also make proteins that help the body grow, fix tissues, and go to the skin to keep it healthy and repair it.
Aging skin loses some stem cell function, but exposure to young serum and bone marrow cells reduces skin's biological age, increases cell production, and improves appearance of skin. Researchers found that bone marrow cells secreted 55 proteins related to aging, and 7 of these proteins had rejuvenating effects, improving visible signs of skin aging, as stated by Popular Mechanics.
Upcoming studies aim to find whether young serum and bone marrow cells can rejuvenate other organs and to measure how long effects last. Researchers said, 'Future studies are needed to validate these proteins for systemic skin rejuvenation and aging, and to explore the effects of longer culture times'. In conclusion, science may finally explain why blood baths, like Countess Bathory's, didn't work: real rejuvenation requires young blood combined with bone marrow cells, as per reports.
FAQs

Family and society should help senior citizens in their fight against ageing: Expert
1 2 Patna: Fighting geriatric problems is not the sole responsibility of the senior citizens alone, but the family and society as a whole need to share the responsibilities in their fight against ageing, said Dr Dineshwar Prasad, former principal of Government Ayurvedic Colleges at Patna and Darbhanga on Thursday. Addressing a meting of some prominent elderly people of the city at Sheikhpura here on the occasion of World Senior Citizen Day, Dr Prasad said that marital and financial status, work history, education, responsibilities and living atmosphere are the prime issues to be considered while addressing the issues of the seniors. Loss of key supports, including death of spouse, retirement, relocation and financial stress adversely affect their lives, he said, further pointing out that advancement of age usually creates numerous physical, psychological, emotional and social problems. "In absence of a healthy lifestyle, most elderly people are affected by anorexia, dementia, depression, stroke, Parkinson's disease and other neurological disorders," said Dr Prasad, suggesting that in old age, diet should be regulated taking into consideration the habitat, season, age, and one's digestive capacity. "The food should be tasty, nutritious, fresh and good in appearance. Liquid intake should be frequent but in small amount. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like If you have a mouse, this game will keep you up all night.

Neem leaf extract helps fight dengue and speeds up recovery: Study
Dengue fever, spread by Aedes mosquitoes, is a rising global health issue, causing high fever, severe joint pain, and extreme fatigue. With no specific cure available, prevention and supportive care are key. Neem (Azadirachta indica), a medicinal tree native to the Indian subcontinent, has long been used in traditional remedies for its antiviral, anti-inflammatory, and mosquito-repelling properties. Recent studies suggest neem may offer multiple benefits in the fight against dengue, from helping block virus replication and supporting immune function, to naturally repelling mosquitoes. Its accessibility and effectiveness make it a promising complementary tool in managing and preventing dengue. Study finds how neem leaf can help treat dengue virus A study published in PubMed found that neem leaves might help stop the dengue virus from spreading in the body. In lab tests, a water-based extract of neem leaves completely blocked the dengue virus type-2 from growing in infected cells, and it didn't harm the cells either. When the same neem extract was tested on mice, it prevented them from showing any signs of dengue, and no virus was found in their blood. This shows that neem could be helpful in fighting dengue, but more research is needed to understand how it works in humans. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Use an AI Writing Tool That Actually Understands Your Voice Grammarly Install Now Undo Neem supports the body during dengue fever While neem is not a cure for dengue, it may support the body in managing symptoms and speeding up recovery. Neem leaves are packed with natural compounds like nimbin and nimbidin, which have shown potential to reduce inflammation, boost immunity, and possibly improve platelet count, an important factor in dengue recovery. Some traditional practices involve drinking neem-infused water or neem tea to manage fever and help the body detox. Health benefits of neem that support dengue prevention and recovery Natural immunity booster: Neem contains compounds like nimbin and nimbolide that help strengthen the immune system, which is essential during and after a dengue infection. Anti-inflammatory properties: Neem helps reduce inflammation in the body, which can ease joint and muscle pain commonly associated with dengue fever. Antiviral action: As mentioned in research, neem leaf extract may help block dengue virus replication, offering a potential line of defence at the cellular level. Supports platelet count: Though more studies are needed, traditional use suggests neem might assist in improving platelet levels, which are often low in dengue patients. Detoxifying effect: Neem is considered a natural blood purifier. Drinking neem-infused water or tea may help cleanse the system and speed up recovery. Skin relief: Neem water or paste can also soothe dengue-related rashes or itching, thanks to its antimicrobial and cooling properties. Neem leaves and dengue: A natural remedy for immunity and recovery Prevention is key when it comes to dengue, and neem plays an important role here too. Neem oil is known to be a natural mosquito repellent. Studies show that applying neem oil (usually mixed with coconut oil) on the skin can repel mosquitoes for up to 12 hours, making it a chemical-free alternative to commercial repellents. Some households even burn dried neem leaves or use neem-based sprays to keep mosquitoes away from living spaces. These practices, while simple, can make a big difference in areas where dengue is common. How to use neem safely at home Neem Use Purpose How to Use Neem tea or boiled neem water May support immunity and reduce fever Boil 5–6 fresh neem leaves in water, let it cool, and drink once a day (not on an empty stomach) Neem oil repellent Protects against mosquito bites Mix 2% neem oil with coconut oil and apply to exposed skin before going outdoors Neem leaf bath Soothes fever and skin irritation Add boiled neem leaves to bathwater and soak for 10–15 minutes Neem water in containers Kills mosquito larvae Add diluted neem oil to stagnant water in flower pots, coolers, and drains Burn dried neem leaves Repels mosquitoes in the home Burn a few dry leaves in a safe, ventilated area (like a veranda) in the evening Also read | Cold showers for heart health: Know the benefits, risks, and other wellness advantages

Does caffeine make anxiety worse? Here's what research shows
Caffeine is a staple in many people's daily routines, especially across the UK. Found in coffee, tea, fizzy drinks, chocolate, and more, it's praised for boosting alertness and energy. However, growing research suggests that caffeine may also play a role in increasing anxiety levels, particularly in sensitive individuals or those with pre-existing mental health conditions. As a stimulant, caffeine activates the central nervous system, which may trigger symptoms like a racing heart, restlessness, and heightened stress. While moderate intake is generally safe, excessive or poorly timed consumption can negatively impact your mental well-being. Here's what science says about caffeine and anxiety. Caffeine can worsen existing anxiety disorders: Understanding the link For individuals living with generalised anxiety, social anxiety, or panic disorder, caffeine can significantly amplify existing symptoms. A systematic review and meta-analysis published in General Hospital Psychiatry examined the acute effects of caffeine on panic attacks and subjective anxiety in patients with panic disorder and healthy controls. The analysis included nine studies involving 237 patients with panic disorder. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like American Investor Warren Buffett Recommends: 5 Books For Turning Your Life Around Blinkist: Warren Buffett's Reading List Undo The findings revealed that more than half of these patients experienced a panic attack following caffeine ingestion, while none had a panic attack after placebo. Furthermore, patients with panic disorder were found to be significantly more vulnerable to panic attacks induced by caffeine compared to healthy controls. Even when caffeine doesn't directly cause anxiety, it can exacerbate physical sensations like a racing heart and jitteriness, which may trigger or worsen panic symptoms How caffeine affects stress, sleep, and anxiety 1. Caffeine may increase anxiety risk, even in healthy individuals Even among those without a diagnosed anxiety disorder, caffeine has been shown to increase subjective feelings of anxiety. Studies suggest that high caffeine consumption is significantly associated with a greater risk of anxiety, particularly when it disrupts sleep. Sleep plays a critical role in emotional regulation. If caffeine keeps you awake or reduces sleep quality, it can indirectly increase your anxiety levels over time. 2. The amount you consume matters The general recommendation for adults is to limit caffeine intake to 400 mg per day. But many common beverages contain more caffeine than expected. Those consuming 400 mg or more daily are more likely to experience anxiety than those who consume less. 3. Caffeine sensitivity varies by individual Not everyone reacts to caffeine the same way. Your genes and metabolism play a significant role: CYP1A2 enzyme: Determines how fast your body breaks down caffeine. Slow metabolisers feel caffeine's effects more intensely and for longer. ADORA2A gene: Influences how caffeine interacts with adenosine receptors. Some people feel more alert, and anxious, based on how their brain responds. If you're highly sensitive, even moderate amounts of caffeine can trigger jitteriness, sleep disturbances, or anxious thoughts. 4. Withdrawing from caffeine can temporarily increase anxiety Caffeine is a stimulant and psychoactive drug, which means regular use can lead to physical dependence. When you stop abruptly, you may experience withdrawal symptoms that overlap with anxiety: Common withdrawal symptoms include: Headaches Irritability Fatigue Difficulty concentrating Increased heart rate Gastrointestinal upset Anxiety-like symptoms These symptoms usually begin within 24 hours and can last up to 9 days. While unpleasant, they're temporary. Most people report feeling calmer and more balanced after withdrawal passes. Hidden sources of caffeine to watch out for Many people underestimate how much caffeine they consume. Besides coffee and tea, caffeine is found in: Energy drinks Fizzy drinks (like cola) Chewing gum Coffee-flavoured ice cream Chocolate and cocoa-based products Over-the-counter medications, including some painkillers and cold/flu remedies Understanding all sources of caffeine is essential if you're trying to reduce your overall intake and manage anxiety more effectively. Tips for managing caffeine and anxiety If you suspect caffeine is impacting your anxiety, here are some practical strategies: Track your intake: Note all sources of caffeine you consume daily. Reduce gradually: Tapering off caffeine can minimise withdrawal symptoms. Avoid caffeine after 2pm: Helps protect your sleep and reduce evening anxiety. Try alternatives: Herbal teas and decaf options can help satisfy cravings without overstimulating your. Listen to your body: If caffeine consistently leaves you feeling restless or anxious, consider cutting back. Also read | Can drinking coffee daily affect your blood sugar levels?
