  • Scientists Made a Gum Disease Gel from Jackfruit Latex, Pomegranate Peel, and Simvastatin — Fights Infection, Reduces Inflammation, and Regrows Bone

    Scientists Made a Gum Disease Gel from Jackfruit Latex, Pomegranate Peel, and Simvastatin — Fights Infection, Reduces Inflammation, and Regrows Bone

    The treatment of severe gum disease has long faced a fundamental limitation: existing therapies can control infection and inflammation, but they cannot rebuild the bone and tissue that periodontitis destroys. A new biomaterial developed by researchers in Brazil — made from three ingredients that would look more at home in a kitchen than a pharmacy — may be closing that gap simultaneously.

    ScienceDaily reported on June 19, 2026 on research published in Polymer Bulletin by scientists at the Pontifical Catholic University of São Paulo (PUC-SP) in Sorocaba, Brazil, led by Professor Eliana Aparecida de Rezende Duek. The team developed a biomaterial combining jackfruit latex, pomegranate peel extract, and simvastatin — a cholesterol-lowering drug — into a mucoadhesive gel that, in early laboratory testing, demonstrated infection control, anti-inflammatory activity, and the ability to promote bone-forming tissue growth within 14 to 21 days.

    “We began to view latex extracted from jackfruit as an interesting alternative, as it has adhesive properties,” explained Professor Duek in the FAPESP Agency press release. “This led us to believe that it could remain longer at the site affected by periodontitis, promoting a more targeted release of therapeutic compounds and potentially reducing the need for systemic antibiotic use.”

    How the Three-Ingredient Combination Works — and Why Each Component Matters

    The biomaterial works through the combined action of three components that address different aspects of the disease process simultaneously — a design principle called multi-modal therapy that is increasingly recognized as essential for treating complex chronic inflammatory conditions.

    Jackfruit latex — the structural vehicle. Jackfruit (Artocarpus heterophyllus) is the world’s largest tree fruit, widely cultivated across South and Southeast Asia and increasingly in Brazil. When freshly harvested, it produces a natural latex — a sticky, adhesive substance that the PUC-SP team recognized as potentially valuable in periodontal treatment. As Phys.org reported: jackfruit latex has mucoadhesive properties — it can stick to mucous membrane surfaces like gum tissue. This adhesiveness is the delivery mechanism: the gel stays at the treatment site rather than washing away with saliva, allowing a “more targeted release of therapeutic compounds” over time.

    Pomegranate peel extract — the antimicrobial. Pomegranate peel extract has documented antimicrobial properties, specifically for topical application against the bacterial pathogens involved in periodontal disease. As Indian Defence Review reported: “Pomegranate extract contributes antimicrobial effects” in the biomaterial. This addresses the infection component of periodontitis — the bacterial accumulation around the gum line that initiates and perpetuates the disease.

    Simvastatin — the bone-forming driver. This is the component that most directly addresses the gap in current periodontal treatment. Simvastatin is widely known as a cholesterol-lowering drug, but it has been studied for an additional and less well-known property: it stimulates bone formation. As The Microbiologist reported: “simvastatin, an anti-inflammatory drug that has been studied for its ability to stimulate bone formation.”

    When administered orally as a cholesterol drug, simvastatin is predominantly captured by the liver, with only a small fraction reaching the systemic circulation, requiring high doses that carry significant side effects, including acute muscle degeneration (rhabdomyolysis). By delivering simvastatin directly into the periodontal pocket via the jackfruit latex gel, the researchers bypass the liver entirely. The drug acts locally, at the site of bone loss, at the concentrations needed for bone regeneration, without the systemic dose and risk profile of oral administration.

    Components Jackfruit latex + pomegranate peel extract + simvastatin
    Jackfruit latex role Mucoadhesive vehicle — stays at treatment site, enables targeted drug release
    Pomegranate peel role Antimicrobial activity against periodontal pathogens
    Simvastatin role Anti-inflammatory + bone formation stimulation

    Advantage of topical simvastatin Bypasses liver; acts at site of bone loss without systemic side effects
    Current periodontitis treatment limitation Controls infection and inflammation but does NOT regenerate bone/tissue
    Periodontitis global prevalence ~47% of U.S. adults over 30; hundreds of millions worldwide

    What Periodontitis Is — and Why Current Treatments Fail Regeneration

    Periodontitis is not simply “gum disease.” It is a chronic inflammatory disease of infectious origin that progressively destroys the supporting structures of the teeth: the periodontal ligament, the alveolar bone, and the cementum that anchors teeth roots. As the disease advances, patients lose the bone that holds their teeth in place — leading to tooth mobility and, eventually, tooth loss.

    Periodontitis affects approximately 47% of American adults over 30, with severe disease affecting approximately 9%. According to GB News’ coverage of the research: “Periodontitis affects hundreds of millions of people worldwide and remains a leading cause of tooth loss in adults.”

    Current standard treatments — scaling and root planing (deep cleaning to remove bacterial deposits) combined with antimicrobial therapy — are effective at controlling infection and halting further destruction. But they cannot regenerate lost bone. “Current treatments are designed to control infection and inflammation, but they generally do little to regenerate damaged periodontal tissue,” the ScienceDaily summary noted. More advanced techniques, including guided tissue regeneration (using barrier membranes to encourage natural tissue growth) and bone grafting, are available but have “inconsistent and sometimes unpredictable” clinical effects.

    A material that simultaneously controls infection, reduces inflammation, AND promotes bone regeneration within 14 days in laboratory conditions — using components that are naturally derived or already clinically approved — represents a meaningful advance over each of these existing approaches, if the results translate to clinical trials.

    Limitations and the Path to Clinical Translation

    The current research is in vitro — laboratory-based testing using human stem cells and physicochemical analysis. It has not been tested in animal models of periodontitis or in human clinical trials. Clinical translation requires multiple additional steps: animal model efficacy studies, safety profiling, formulation optimization for clinical application, and ultimately clinical trials comparing the biomaterial to existing treatments.

    Professor Duek and her team have expressed confidence in the material’s potential: “We observed that the developed biomaterial has great potential for future applications in treating periodontitis and in other areas as well.” The fact that simvastatin is already an FDA-approved drug with a well-established safety profile in humans is an advantage — not for its oral use, but because basic pharmacological safety data already exists, which may reduce some regulatory pathway complexity for the topical application.

    Frequently Asked Questions

    What is the jackfruit/pomegranate gum disease biomaterial?

    A mucoadhesive gel combining jackfruit latex, pomegranate peel extract, and simvastatin developed by PUC-SP researchers in Brazil and published in Polymer Bulletin(March 2026; ScienceDaily June 19, 2026). It sticks to gum tissue at the treatment site, fights infection with pomegranate’s antimicrobial properties, and uses locally delivered simvastatin to stimulate bone formation.

    What makes this different from current gum disease treatments?

    Current treatments (scaling, root planing, antimicrobials) can control infection and halt disease progression, but cannot rebuild lost bone. The jackfruit biomaterial is designed to do all three simultaneously: fight infection, reduce inflammation, and promote bone-forming tissue growth within 14 days in laboratory tests.

    Has this been tested in humans?

    Not yet. The current research is in vitro, using human adipose-derived stem cells in laboratory conditions. Animal model studies and clinical trials would be needed before clinical application. The study is a promising proof-of-concept finding, not a clinical treatment.

    Why use simvastatin in a gum disease treatment?

    Simvastatin is a cholesterol drug with the additional property of stimulating bone formation. When administered directly to the periodontitis site in the biomaterial gel, it bypasses the liver and acts locally at concentrations that promote bone growth — without the systemic side effects (including muscle damage) that can occur with high oral doses.

    Why jackfruit latex specifically?

    Jackfruit latex is naturally adhesive (mucoadhesive) — it sticks to gum tissue rather than washing away with saliva. This keeps the therapeutic compounds at the treatment site for prolonged local release, potentially reducing the need for systemic antibiotic use.

  • Busy Times, or Anytime: Nine Ways Mindfulness Reduces Stress

    Busy Times, or Anytime: Nine Ways Mindfulness Reduces Stress

    You’ve probably heard that mindfulness reduces stress levels. But how does it help? Shamash Alidina shares the research—plus, a meditation you can turn to anytime.

    You’ve probably heard that mindfulness reduces stress. But how does it actually help you do that?

    Mounting scientific evidence from hundreds of universities—including dedicated centers at the University of Massachusetts Medical School in the United States and the University of Oxford in the United Kingdom—strongly suggests that mindfulness gently builds an inner strength, so that future stressors have less impact on our happiness and physical well-being.

    Here are nine ways mindfulness can help you manage stress, plus a guided meditation to start experiencing the natural calm that mindfulness can bring:

    Nine Ways Mindfulness Reduces Stress

    1. You become more aware of your thoughts. You can then step back from them and not take them so literally. That way, your stress response is not initiated in the first place.
    2. You don’t immediately react to a situation. Instead, you have a moment to pause and then use your “wise mind” to come up with the best solution. Mindfulness helps you do this through the mindful exercises.
    3. Mindfulness switches on your “being” mode of mind, which is associated with relaxation. Your “doing” mode of mind is associated with action and the stress response.
    4. You are more aware and sensitive to the needs of your body. You may notice pains earlier and can then take appropriate action.
    5. You are more aware of the emotions of others. As your emotional intelligence rises, you are less likely to get into conflict.
    6. Your level of care and compassion for yourself and others rises. This compassionate mind soothes you and inhibits your stress response.
    7. Mindfulness practice reduces activity in the part of your brain called the amygdala. The amygdala is central to switching on your stress response, so effectively, your background level of stress is reduced.
    8. You are better able to focus. So you complete your work more efficiently, you have a greater sense of well-being, and this reduces the stress response. You are more likely to get into “the zone” or “flow,” as it’s termed in psychology by Mihaly Csikszentmihalyi.
    9. You can switch your attitude to the stress. Rather than just seeing the negative consequences of feeling stressed, mindfulness offers you the space to think differently about the stress itself. Observing how the increased pressure helps energize you has a positive effect on your body and mind.

    Try It Yourself—Stress SOS: A Quick Practice When You Need It Most

    1. Bring to mind a current challenge in your life that is the cause of some stress. A situation that you’re willing to work with at the moment. Not your biggest challenge but not so small that it causes no stress at all. A 3 on a scale of 1–10 is a good guide.
    2. Bring the situation vividly to mind. Imagine being in the situation and all the difficulties associated with it.
    3. Notice whether you can feel the stress in your body. Physical tension, faster heart rate, a little bit of sweating, butterflies in your stomach, tightness in the back or shoulders or jaw, perhaps. Look out for your stress signals.
    4. Tune in to your emotions. Notice how you feel. Label that emotion if you can, and be aware of where you feel the emotion, exactly, in your body. Just try to spot it as best you can. The more precisely you can locate the emotion and the more you notice about the sensation, the better. With time and experience, you’ll keep getting better at this.
    5. Bring mindful attitudes to the emotion. These include curiosity, friendliness, and acceptance.
    6. Try placing your hand on the location of the sensation—a friendly hand representing kindness. Do it the way you would place your hand on the injured knee of a child, with care and affection.
    7. Feel the sensation together with your breathing. This can promote a present-moment awareness and mindful attitudes to your experience.
    8. When you’re ready, bring this meditation to a close.

  • Vaccine To Protect Against Dementia? This One Reduces Risk By 20%

    Vaccine To Protect Against Dementia? This One Reduces Risk By 20%

    As dementia and Alzheimer’s cases continue to rise, researchers are exploring new ways to curb their impact. But a surprising breakthrough suggests that protection might already be within reach. A recent study suggests that shingles vaccine, which protects against the painful viral rash, may also reduce the risk of dementia in older adults.

    Earlier studies have shown that there is reduced dementia risk among those vaccinated with shingles. However, many were biased, as vaccinated individuals tend to be more health-conscious, making it difficult to determine whether the vaccine itself offered protection or if lifestyle factors like diet and exercise played a role.

    To address this, researchers at Stanford Medicine took advantage of an unusual public health policy in Wales. In 2013, a shingles vaccination program set strict age-based eligibility rules: those who were 79 on September 1 could receive the vaccine that year, while those who turned 80 before the cutoff were never eligible.

    The two groups had similar education levels, vaccination habits, and rates of conditions like diabetes and heart disease. This created a unique opportunity to compare two nearly identical groups, differing only in vaccine access, allowing researchers to isolate the vaccine’s true impact from lifestyle factors.

    “What makes the study so powerful is that it’s essentially like a randomized trial with a control group — those a little bit too old to be eligible for the vaccine — and an intervention group — those just young enough to be eligible,” said Dr. Pascal Geldsetzer, senior author of the study in a news release.

    The study showed that those who received the shingles vaccine were 20% less likely to develop dementia over the next seven years than those who did not receive the vaccine. The researchers also noted that the protection against dementia was notably stronger in women than in men. This is possibly due to sex differences in immune response or the difference in the way dementia develops.

    “For the first time we are able to say much more confidently that the shingles vaccine causes a reduction in dementia risk. If this truly is a causal effect, we have a finding that’s of tremendous importance,” Dr. Geldsetzer added.

  • Just 5 Minutes Of Daily Exercise Reduces Dementia Risk By 41%

    Just 5 Minutes Of Daily Exercise Reduces Dementia Risk By 41%

    Staying active is one of the most effective ways to support long-term health and lower the risk of dementia. However, not everyone has the time, ability, or motivation for structured workouts every day. Here’s some good news- new research suggests even small amounts of movement can still give significant protection against dementia.

    A recent study published in the Journal of Post-Acute and Long-Term Care Medicine found that just 35 minutes of moderate to vigorous physical activity per week, which is about 5 minutes a day, lowered the risk of developing dementia by 41% compared to those who never exercised.

    “Our findings suggest that increasing physical activity, even as little as five minutes per day, can reduce dementia risk in older adults. This adds to a growing body of evidence that some exercise is better than nothing, especially with regard to an aging-related disorder that affects the brain that currently has no cure,” said lead author Amal Wanigatunga in a news release.

    The findings were made after following up nearly 90,000 adults with an average age of 63, for about 4.4 years. During the study period, the researchers tracked the physical activity levels and health of the participants and noted that 735 of them developed dementia. On average, participants engaged in 126 minutes of moderate to vigorous physical activity per week.

    The study found that for every additional 30 minutes of moderate to vigorous physical activity per week, the risk of developing dementia decreased by 4%. While even small amounts of movement help, the researchers noticed a clear pattern, a dose-response relationship between exercise and reduced dementia risk. This means that more people exercised, the greater the benefits.

    Those who engaged in 36 to 70 minutes of moderate to vigorous activity per week saw their dementia risk drop by 60%, while those who exercised for 71 to 140 minutes experienced a 63% reduction. The biggest impact, however, was among individuals who exceeded 140 minutes per week, slashing their risk by an impressive 69%.

    “Our results suggest engaging in any additional amount of MVPA [moderate to vigorous physical activity] reduces dementia risk, with the highest benefit appearing among individuals with no MVPA. These associations are not substantially modified by frailty status,” the researchers concluded.

  • ADHD Reduces Life Expectancy? Here’s How It Affects Men And Women Differently

    ADHD Reduces Life Expectancy? Here’s How It Affects Men And Women Differently

    As ADHD diagnoses continue to rise in the U.S., researchers have uncovered a troubling link between the behavioral disorder and reduced life expectancy, with the impact varying between men and women.

    Attention Deficit Hyperactivity Disorder (ADHD) is one of the most common neurodevelopmental disorders affecting children. The condition can impact various aspects of life, including academic performance, professional achievements, interpersonal relationships, and daily functioning.

    In a large-scale study published in The British Journal of Psychiatry, researchers analyzed data from over 300,000 participants with ADHD, comparing it with a similar group without the condition to understand its effects on longevity. The findings revealed that men with ADHD had a life expectancy reduction of 4.5 to 9 years, while women faced a reduction of 6.5 to 11 years.

    “It is deeply concerning that some adults with diagnosed ADHD are living shorter lives than they should. People with ADHD have many strengths and can thrive with the right support and treatment. However, they often lack support and are more likely to experience stressful life events and social exclusion, negatively impacting their health and self-esteem,” said senior author, Professor Josh Stott in a news release.

    The researchers also noted that only a fraction of the total population of adults with ADHD could be studied as less than one in nine adults with ADHD had been diagnosed.

    “We know from studies of traits in the community and from studies of childhood diagnosis that the rate of ADHD in our sample is just a fraction of what it should be,” Professor Stott added.

    Since the condition often goes undiagnosed, particularly in adults, this new research may overestimate the reduction in life expectancy for those with the condition. The study findings may not be generalizable to other geographies or settings, the researchers caution. Also, since the study has not evaluated data on the specific causes of death, it is not possible to directly attribute the years of lost life to different factors.

    However, researchers noted that early deaths in ADHD patients could be “caused by modifiable risk factors and unmet support and treatment needs in terms of both ADHD and co-occurring mental and physical health conditions.”

  • Just 80 Minutes Of Weekly Exercise Reduces Baby Blues, Postpartum Depression Symptoms: Says Study

    Just 80 Minutes Of Weekly Exercise Reduces Baby Blues, Postpartum Depression Symptoms: Says Study

    For new moms who are looking for an all-natural way to ease their baby blues or depression, here’s some good news: a brisk walk or yoga might be just what you need to relieve symptoms. Researchers have found that mothers who engage in exercise programs with at least 80 minutes of moderate activity each week experience significant reductions in the severity of baby blues and postpartum depression.

    Postpartum depression is a serious mental health condition impacting over 10% of women in the first year after childbirth. Hormonal shifts, genetic predisposition, and environmental factors can trigger it. In contrast, the ‘baby blues’ is a milder, temporary form of depression that usually fades within a few weeks as hormone levels stabilize.

    Researchers behind the latest study investigated the benefits of exercise on maternal mental health by evaluating 35 studies involving 4072 participants from 14 countries. Participants exercised at different frequencies, from 1 to 5 days a week, with sessions lasting between 15 and 90 minutes. Activities included aerobic exercise, strength training, stretching, yoga, and combinations of these forms.

    “Pooled data analysis of the study results showed that compared with no exercise, exercise-only interventions were associated with less severe symptoms of depression and anxiety after giving birth and an almost halving in the odds (45%) of developing major postpartum depression,” the news release stated.

    Although with an increase in exercise volume, there were greater reductions in depression symptoms, researchers noted significant positive effects, even with a minimum threshold of 80 minutes per week of moderate activities spread across at least four days. Moderate activities included brisk walking, water aerobics, stationary cycling, and resistance training with bands, weights, or body weight.

    Based on these findings, researchers recommend starting postpartum exercise within the first three months after childbirth for improved mental health.

    “The findings of this review show the efficacy of exercise in improving mental health outcomes for postpartum individuals. Given the comparable effectiveness we observed of postpartum exercise in reducing depressive symptom severity to conventional treatments, exercise could provide mothers with relatively safe, accessible and inexpensive alternatives to address mental health conditions,” the researchers wrote in the study published in the British Journal of Sports Medicine.

    “Additionally, using exercise to improve postpartum mental health could reduce current concerns with conventional treatment options, such as the largely unknown long-term effects of antidepressant use during lactation on the child or prohibitive costs of regular psychosocial therapy visits,” they added.

  • Three cups of coffee daily boosts heart health, reduces cardiometabolic multimorbidity risk: study

    Three cups of coffee daily boosts heart health, reduces cardiometabolic multimorbidity risk: study

    Can’t start your day without coffee? A recent study reveals that your morning ritual might do more than just wake you up, it could also benefit your heart health. The research found that moderate caffeine intake, or three cups of coffee daily, significantly reduces the risk of cardiometabolic multimorbidity.

    Cardiometabolic multimorbidity refers to having at least two coexisting cardiometabolic diseases. Studies indicate that having a single cardiometabolic condition doubles the risk of death from all causes. In contrast, individuals with cardiometabolic multimorbidity may face a risk of all-cause mortality that is four to seven times higher.

    According to the latest study published in the Journal of Clinical Endocrinology & Metabolism, any level of coffee and caffeine consumption could play an important protective role in all phases of cardiometabolic multimorbidity development.

    After analyzing the caffeine consumption of over 500,000 participants from the UK Biobank who are part of a detailed longitudinal dietary study, researchers noted that compared with non-consumers or those who take less than 100mg of caffeine per day, moderate consumption of coffee, meaning three drinks per day or 200–300 mg of caffeine had the lowest risk for new-onset cardiometabolic multimorbidity.

    The study focused on participants aged 37 to 73, excluding those with unclear caffeine intake data. This resulted in a pool of 172,315 individuals free of cardiometabolic diseases at the start, for analyzing caffeine effects. Additionally, a separate group of 188,091 participants was included to examine the impact of coffee and tea consumption.

    The results suggest that those who drank three cups a day experienced a 48.1% reduction in risk, while those consuming 200–300 mg of caffeine daily saw a 40.7% decrease, compared to individuals who either did not consume caffeine or had less than 100 mg per day.

    “Consuming three cups of coffee, or 200–300 mg caffeine, per day might help to reduce the risk of developing cardiometabolic multimorbidity in individuals without any cardiometabolic disease,” said the study’s lead author, Chaofu Ke in a news release.

    “The findings highlight that promoting moderate amounts of coffee or caffeine intake as a dietary habit for healthy people might have far-reaching benefits for the prevention of cardiometabolic multimorbidity,” Ke said.
