HEALTH NEWS Melatonin may safely reduce chronic musculoskeletal pain, study findsStudy: Nordic Walking Reduces Depression Symptoms Within WeeksConnection or compulsion: How smartphones can deepen depression in older adultsThis Popular Workout Supplement May Give Cancer Immunotherapy a Big BoostProbiotic metabolite found to suppress melanoma tumor growth in mice Melatonin may safely reduce chronic musculoskeletal pain, study findsUniversity of Sydney, June 30 2026 (News-Medical)
A sleep supplement widely used to treat insomnia could help reduce reliance on some of the most common and potentially harmful pain medications, new research from the University of Sydney suggests.
Published in PAIN, the study found melatonin can reduce chronic musculoskeletal pain with effects in a similar range to medications such as opioids, non-steroidal anti-inflammatory drugs (NSAIDs) and paracetamol.
The study analyzed data from 2028 adults across 23 randomised controlled trials conducted in countries including the United States, Russia, Brazil, Egypt and China. Participants included people with conditions such as low back pain, osteoarthritis and fibromyalgia, as well as those recovering from surgeries including joint replacements and spinal procedures.
On average, the study found that melatonin reduced pain by around nine points on a 0-100 scale, with the most rigorous trials showing reductions closer to 10 points, a similar magnitude to widely used pain medications.
Across the trials, the dose and timing of melatonin varied depending on the condition and setting. For chronic musculoskeletal pain, doses typically ranged from 3 to 10 mg, with 3 mg per day the most commonly used. For postoperative pain, doses ranged from 1 to 10 mg, with 5 to 6 mg most common. Melatonin was generally taken at bedtime or up to one hour before sleep.
Study: Nordic Walking Reduces Depression Symptoms Within Weeks
Université Grenoble Alpes (France), July 1 2026 (Natural News) A randomized controlled trial published in the Journal of Affective Disorders found that supervised Nordic walking significantly reduced depression symptoms in adults with moderate to severe depression. The most pronounced improvements occurred within the first five weeks of the 10-week program, according to researchers. The study enrolled 64 adults, with 48 assigned to Nordic walking and 16 to a non-active control group.The findings challenge the commonly cited three-month timeframe for exercise benefits on depression.
A secondary analysis examined whether participants with severe depression responded differently than those with moderate symptoms. According to the study, Nordic walking is a low-impact activity that engages the upper and lower body using poles, similar to cross-country skiing.
The Nordic walking group showed significantly greater reductions in depression symptoms compared to the control group over the full 10 weeks. The largest reduction occurred from baseline to week five, with a large effect size; improvements from week five to week ten were smaller and not statistically significant. Participants with severe depression at baseline experienced even larger and faster improvements in the first five weeks, according to the secondary analysis.
Connection or compulsion: How smartphones can deepen depression in older adultsRutgers University, July 1 2026 (Eurekalert)
Compulsive smartphone habits in older adults can be linked to a higher risk of depression, according to a study led by a Rutgers researcher.
Researchers said their findings raised concerns that technology widely promoted to build connections can instead deepen late-life isolation: While mobile devices can be invaluable lifelines, their impact on mental health depends heavily on the way people use them. A critical distinction, the researchers said, is whether someone uses technology to actively engage with the world or to withdraw.
The study, published in JMIR Aging, drew on survey responses from 2,585 adults ages 60 and older living in 87 communities. Researchers collected health and demographic information, including age, gender, marital status, education and income, and measured depressive symptoms with a screening tool commonly used with older adults.
Limited social participation emerged as the strongest predictor of depression, followed closely by smartphone addiction, defined as compulsive or excessive use that disrupts daily functioning. Problematic phone reliance appeared in nearly all cases of clinical depression, with older adults who rarely used interactive communication features facing the greatest risk.
Another high-risk pattern emerged among older adults of both sexes: Those with higher incomes and education levels who suffered from smartphone addiction were more prone to clinical depression. This finding suggests that wealth, education, and technology access fail to protect against loneliness when screen time replaces real-world connections.
This Popular Workout Supplement May Give Cancer Immunotherapy a Big BoostUniversity of California at Los Angeles, July 1, 2026 (SciTech Daily)Creatine, a supplement widely used by athletes and bodybuilders, may also strengthen the immune system’s ability to fight cancer, according to new research from UCLA.
Previous findings from the same research team show that creatine boosts the activity of killer T cells, which destroy cancer cells. The new research found that creatine also supports dendritic cells, the immune cells responsible for detecting tumor material and activating killer T cells to launch an attack.
Although many approved cancer immunotherapies target killer T cells, only about 20% to 40% of patients benefit from these treatments. Enhancing dendritic cells, which prepare and activate T cells, could improve the effectiveness of immunotherapy for more people.
The researchers found that dendritic cells inside tumors produced much higher levels of the gene responsible for the creatine transporter, the protein that moves creatine into cells, than dendritic cells found in healthy tissue.
They investigated whether increasing creatine could improve dendritic cell performance. Daily creatine injections in mouse models of melanoma slowed tumor growth while increasing both the number and activity of dendritic cells within tumors. The treated dendritic cells also released more chemical signals that attracted additional immune cells to the tumor.
Probiotic metabolite found to suppress melanoma tumor growth in miceSouthern Medical University (China), June 30 2026 (News-Medical) Immune checkpoint inhibitors like anti-PD-1 have transformed melanoma treatment, yet more than half of patients fail to respond or eventually develop resistance. The tumor microenvironment and the gut microbiome are increasingly recognized as critical determinants of immunotherapy outcomes. Melanoma patients often show reduced levels of beneficial gut bacteria, including Bifidobacterium, and lower microbial diversity.Researchers have discovered that Bifidobacterium animalis—a probiotic commonly found in fermented dairy products—produces mannose, which activates CD8⁺ T cells and suppresses melanoma progression in mouse models. The study reveals a novel gut-microbiome-immune axis that could lead to new adjuvant strategies for melanoma immunotherapy. When given orally to mice with melanoma tumors, the bacterium significantly reduced tumor volume and weight—without ever colonizing the tumor tissue itself, indicating that its effects were mediated entirely through secreted metabolites.Using size fractionation and metabolomics, the team identified mannose as the key bioactive molecule—a small, non-protein compound under 3 kilodaltons. In mice, drinking water supplemented with 1% mannose replicated the anti-tumor effects of the live probiotic, increasing tumor-infiltrating CD8⁺ T cells and boosting their production of killer molecules like granzyme B (GZMB), interferon-gamma (IFN-γ), and tumor necrosis factor-alpha (TNF-α). -

HEALTH NEWS Study links low vitamin C levels in the blood plasma to reduced brain connectivityStudy: Tart Cherry Supplementation Alters Muscle Protein Profile After ExerciseSocioeconomic factors may leave more lasting imprint on children's brains than IQ or parenting styleFasting-mimicking diet reduces gum disease inflammationLow blood pressure shows strongest link to Alzheimer's disease Study links low vitamin C levels in the blood plasma to reduced brain connectivityHirosaki University (Japan), June 10 2026 (News-Medical)
Previous research has uncovered associations between diets higher in vitamin C and lower risk of cognitive impairment in older adults. However, few studies have looked directly at vitamin C levels in blood plasma and potential associations with brain structure and connectivity within brain networks. To help fill that gap, Nagaya and colleagues analyzed magnetic resonance imaging (MRI) scans and plasma vitamin C levels of 2,044 adults over the age of 64.
Specifically, they measured the volume of each participant's gray and white brain matter (accounting for individual differences in total brain volume between participants). They also evaluated connectivity within the default mode network, which is associated with several cognitive functions, such as attention and autobiographical memory.
After statistically accounting for other factors the researchers found that participants with lower plasma vitamin C levels tended to have lower gray matter volume, as well as lower connectivity within the default mode network.
These findings suggest the possibility that optimal levels of vitamin C in blood plasma could potentially support cognitive function and counteract cognitive decline. However, the findings do not confirm any such cause-effect relationship between vitamin C levels and brain health.
Study: Tart Cherry Supplementation Alters Muscle Protein Profile After Exercise
University of Exeter (UK), June 11 2026 (Natural News)
Researchers recruited 34 healthy, recreationally active young men and assigned them to receive either a placebo, a low-dose tart cherry concentrate, or a high-dose tart cherry supplement, according to the study report. Participants consumed their assigned supplement for seven days before completing a muscle-damaging workout and continued supplementation for three days afterward, for a total intervention of 10 days.
The study found that tart cherry supplementation significantly altered the muscle's protein profile following exercise-induced damage. Changes were observed in proteins involved in muscle structure, contraction, cellular repair processes, and immune-cell activity within muscle tissue. These findings suggest that tart cherry polyphenols may influence the way muscles respond to and recover from the stress of exercise.
Researchers also detected significant increases in hippuric acid, a compound produced when gut microbes break down polyphenols from tart cherries and other plant foods. Participants with higher levels of hippuric acid tended to maintain better muscle function following exercise-induced damage.
Socioeconomic factors may leave more lasting imprint on children's brains than IQ or parenting styleWashington University in St. Louis, June 11 2026 (Medical Xpress)
After analyzing hundreds of biological, psychological, social and environmental factors related to children's development, researchers at Washington University School of Medicine in St. Louis found that a family's financial situation and the resources and opportunities in a child's neighborhood had the strongest connection to brain development.
Socioeconomic factors accounted for about 16% of the variability in measures of children's brain function—far more than IQ, parenting style and health history. As part of the study, the researchers analyzed brain scans from nearly 12,000 children ages 9 to 10 to see how a child's environment, health and regular activities are related to brain development. Of the hundreds of factors examined, the team found that the socioeconomic status of a child's family had the strongest relationship with that child's brain structure and function.
Further, the parts of the brain that reflect socioeconomic factors were the same areas most sensitive to sleep and stress, suggesting that socioeconomic disadvantage affects the brain indirectly through disrupted sleep and chronic stress.
Of the top 40 variables linked to brain function, 37 were socioeconomic, and of the top 40 tied to structure, 35 were socioeconomic. These included the social and economic resources in the child's neighborhood, akin to the overall wealth of an area. Strong influences included family income, homeownership, poverty rates and access to transportation. The remaining top variables were related to sleep, screen time and stress.
Fasting-mimicking diet reduces gum disease inflammationKings College London, June 11 2026 (Eurekalert)People who follow a short-term low-calorie diet may have reduced markers of inflammation associated with gum disease. A new study by King’s College London highlights how lifestyle modifications could be important alongside plaque control in managing gum disease.
The research included 28 patients from across hospitals in Spain, split into two groups – those who followed a five-day restrictive diet, versus a control group who continued their usual diet. Patients who fasted ate 1,100 calories for two days, then 750 calories for three days. The sixth day gently introduced more calories with soft foods – then their diets returned to normal by the seventh day. This was repeated three times in six months, with patients reporting the diet easy to stick to.
After six months, samples were analysed from the patients’ blood and gingival crevicular fluid – liquid that comes from the small space between your tooth and gum, which helps gums stay healthy and fight germs.
Those who fasted had reduced markers of inflammation in samples from blood and gum tissue compared to those whose diets stayed the same, including lower levels of C-reactive protein, a general indicator of inflammation around the body. The fasting group also had reduced molecules linked to inflammation specifically in the gums, compared to controls.
Low blood pressure shows strongest link to Alzheimer's diseaseMichigan Technological University, Jun 10 2026 (News-Medical)Numerous types of cardiovascular disease and CVD risk factors were linked to a higher risk of Alzheimer's disease, with low blood pressure showing the strongest connection, according to a new analysis published today in the Journal of the American Heart Association
What are the key findings of the analysis?
Adults with hypotension (low blood pressure) were about three times more likely to develop Alzheimer's and nearly twice as likely in the All of Us study when compared to individuals who did not have low blood pressure.Across both datasets, adults with high blood pressure (hypertension) were 1.6 times more likely to have Alzheimer's disease, compared to people without hypertension.Participants who had a previous stroke had a 1.5 times higher risk for Alzheimer's disease in the UK Biobank and 1.85 times in All of Us.Those with irregular heartbeat (or atrial fibrillation, also called AFib) were about 1.5 times more likely to have Alzheimer's disease compared to those without AFib. -
HEALTH NEWS Ginger Supplementation Reduces Muscle Soreness, Review FindsArtificially sweetened and sugar-sweetened beverage intake and risk of liver cancerPlant-based quinoa burgers reduce post-meal blood sugar spikesSleep and exercise may curb heart risk from mutant white blood cellsPregnant women may reduce key health risk through less sitting, more light exercise Ginger Supplementation Reduces Muscle Soreness, Review FindsOld Dominion University, June 4 2026 (Natural News) A review published in Nutrition Reviews found that consuming 2 grams of ginger daily for 11 consecutive days before exercise reduced delayed-onset muscle soreness (DOMS) by 23% to 25%.
The review examined multiple placebo-controlled studies and found that single doses taken just before exercise did not produce significant pain reduction, but consistent daily intake over the 11-day period yielded measurable results.
DOMS typically occurs 24 to 72 hours after exercise and is a common reason individuals skip subsequent workouts. In two placebo-controlled studies reviewed, participants consumed 2 grams of either raw or heat-treated ginger daily for 11 days before performing eccentric exercise, which lengthens muscles under tension.
The effective dose identified in the review was 2 grams per day, roughly equivalent to one teaspoon of fresh grated ginger.
Artificially sweetened and sugar-sweetened beverage intake and risk of liver cancerYale University, National Cancer Institute, Boston University, June 10 2026 (Eurekalert)
Are artificially sweetened beverage (ASB) and sugar-sweetened beverage (SSB) intakes associated with risk of liver cancer overall and by subtype (hepatocellular carcinoma [HCC] and intrahepatic cholangiocarcinoma [ICC])?
In this pooled analysis of 11 prospective cohort studies comprising 1,518,411 adults, SSB intake per 1-beverage/day increment was associated with increased risk of HCC and ICC, whereas ASB intake was not associated with liver cancer overall or by subtype.
There was no evidence of effect modification by diabetes status.
Plant-based quinoa burgers reduce post-meal blood sugar spikesFederal University of Golas (Brazil), June 10 2026 (News-Medical)A study published in ACS Nutrition Science suggests that a plant-based burger made from baru pulp and red quinoa could reduce post-meal blood glucose responses in healthy adults.
Red quinoa (Chenopodium quinoa Willd.) is a pseudocereal that is rich in protein, fiber, and micronutrients. It provide spolyphenols that have been shown to slow gastric emptying and overall digestion, and may reduce enzymatic degradation of carbohydrates in the gut. This would influence the rate at which glucose is absorbed into the bloodstream after a meal, altering the GI.
The authors of this pilot study examined GI in a small sample of eight volunteers after consuming two plant-based burgers: one made with baru pulp and red quinoa, and the other with red quinoa alone.
All three foods produced their highest blood glucose levels 30 minutes after consumption. The glucose reference food generated the largest peak at 174 mg/dL, while the baru pulp–red quinoa and red quinoa burgers reached substantially lower peaks of 118 mg/dL and 120 mg/dL, respectively. By 120 minutes, blood glucose levels had declined in all groups.
Compared with the glucose reference, both plant-based burgers caused only modest increases in blood glucose relative to fasting levels: 15.5% for the red quinoa burger and 18% for the baru pulp–red quinoa burger.
Sleep and exercise may curb heart risk from mutant white blood cellsMount Sinai Hospital, June 10. 2026 (Medical Xpress)
Healthy sleep and regular exercise can work to counteract genetic mutations in white blood cells that are associated with cardiovascular disease and are most common among older people, Mount Sinai researchers have found. In a study published in Nature, the team reported for the first time that sufficient sleep and exercise can help reduce the cancer-like cell expansion and atherosclerotic risk linked to mutations that spontaneously occur in white blood cells.
These mutations accumulate over our lifetimes and occur most often in hematopoietic stem cells, which are the cells in bone marrow that make blood cells, including macrophages and monocytes, immune cells that help defend the body. When these cells develop mutations, they start to proliferate, multiplying faster than they should, and become more inflammatory, irritating or damaging tissues in the body. This condition, known as clonal hematopoiesis (CH), is detectable in a quarter of people over age 70 and half of people over 80, though it is infrequent in young, healthy people.
Healthy sleep and exercise was found to selectively influence immune cells with clonal hematopoiesis mutations, repressing their proliferative programming and expansion, as well as their ability to promote the formation of harmful plaque in the arteries of the heart.
The findings reveal that CH mutant cells are malleable and selectively responsive to lifestyle behavior in a way that can mitigate atherosclerotic risk.
Mount Sinai researchers discovered that moderate-to-vigorous physical activity was associated with a reduced incidence of gene-specific CH and fewer mutant cells in the blood. Sufficient sleep and exercise "turned off" the detrimental effects of rogue Jak2 and Tet2 mutant CH hematopoietic stem cells in the bone marrow, decreasing their ability to proliferate and grow, a precancerous process known as "clonal expansion.
Pregnant women may reduce key health risk through less sitting, more light exerciseUniversity of Iowa, June 10 2026 (Eurekalert)
Women who engage in light physical activity and lessen their sedentary time may significantly reduce the risk of key health problems during pregnancy, according to a new University of Iowa-led study.
Researchers examined the daily behaviors of 470 pregnant women across all stages of pregnancy. Each participant wore a monitor that measured physical activity in 24-hour cycles and another monitor that recorded the time they spent asleep.
Based on observational data collected from the study’s participants, the researchers propose a “Goldilocks Day”-like guide for pregnant women that could reduce by nearly 30% the risk of developing hypertensive disorders of pregnancy (HDP), commonly occurring complications of pregnancy that include chronic hypertension, gestational hypertension, and preeclampsia.
Those recommendations are:
• Reduce sedentary time to fewer than eight hours each day.
• Engage in light physical activity for at least seven hours each day.
• Engage in approximately 22 minutes of moderate to vigorous physical activity, such as a brisk walk, each day.
• Get nearly nine hours of sleep each night.

Gary Null breaks down the idea of intersectionality
: the complex, cumulative way in which the effects of multiple forms of discrimination (such as racism, sexism, and classism) combine, overlap, or intersect especially in the experiences of marginalized individuals or groups[Kimberlé] Crenshaw introduced the theory of intersectionality, the idea that when it comes to thinking about how inequalities persist, categories like gender, race, and class are best understood as overlapping and mutually constitutive rather than isolated and distinct.
Key ConceptsOverlapping Identities: A person's identity is multidimensional. You cannot separate a person's race from their gender, socioeconomic status, or sexual orientation.Compounding Inequality: Instead of simply adding different forms of discrimination together (e.g., sexism plus racism), these overlapping factors can create an entirely unique and often magnified form of oppression or disadvantage.Context Matters: Intersectionality helps analyze how societal structures and power dynamics interact with an individual's specific identities in varying situations
