HEALTH NEWS Review finds blueberry and grape polyphenols may improve vascular health Plant compound shows promise for treating rheumatoid arthritis at its source, study finds Screen Time at Ages 1 and 6 Linked to Lasting Learning and Memory Effects Some caffeinated drinks are linked to poorer memory Study: Morning Exercise Linked to Lower Daily Calorie Intake Compared to Evening Workouts Review finds blueberry and grape polyphenols may improve vascular health Universidad Católica de Murcia (Spain), July 27 2026 (News-Medical) A recent review published in the journal Nutrients examined the evidence on the effects of blueberries, grapes, and their bioactive compounds on cardiovascular risk markers. In the present study, a comprehensive systematic literature search was conducted to identify randomized controlled trials (RCTs), systematic reviews, and meta-analyses published from January 2015 through April 2026. Two systematic reviews and meta-analyses reported that grape polyphenols at doses exceeding 500 mg/day for at least 12 weeks significantly reduced C-reactive protein levels, while the other reported improvements in vascular function or BP in 84% of the human studies it assessed, including a significant reduction in systolic BP. One found a modest reduction in BP and improvement in endothelial function with flavan-3-ol foods, such as tea, apples, cocoa, and grape-derived products. Moderate- and high-quality RCTs reported improvements in lipid peroxidation, lipid profiles, flow-mediated dilation, diastolic BP, and paraoxonase activity. Resveratrol and blueberry RCTs mainly reported endothelial and vascular benefits, such as improved nitric oxide production and flow-mediated dilation and reduced BP and inflammatory markers. One high-quality RCT involving older men with metabolic syndrome showed significant improvements in arterial stiffness and endothelial function after six months of daily blueberry consumption. Plant compound shows promise for treating rheumatoid arthritis at its source, study finds Guangzhou University of Chinese Medicine, July 27 2026 (Natural News) A plant-derived compound called obakulactone (OL) reduced swelling, inflammation and joint damage in rats with rheumatoid arthritis, according to a study published in Engineering. The compound, a tetracyclic triterpenoid from the bark of Phellodendri cortex, also rebalanced immune activity and corrected disrupted fatty acid metabolismd. P. cortex has been used in traditional medicine and contains OL along with other constituents, Researchers tested OL in rats with rheumatoid arthritis, administering low, medium and high doses for 21 days. Treatment significantly reduced joint swelling and helped restore the normal structure of cartilage and the synovium, the tissue lining the joints, according to the report. Blood tests showed dose-dependent decreases in inflammatory molecules including IL-1, IL-6, IL-17 and TNF, as well as rheumatoid arthritis markers RF, CCP-Ab, CRP and MMP-3, officials said. The compound also reduced abnormally high levels of CD3+ T cells and CD68+ macrophages within the joints and shifted macrophages from a proinflammatory M1 state toward an anti-inflammatory M2 state. Screen Time at Ages 1 and 6 Linked to Lasting Learning and Memory Effects National University of Singapore & Zhejiang University (China), July 28, 2026 (SciTech Daily) A study that tracked children from age 1 through age 8 found that greater screen viewing time, especially during infancy and near the start of school, was associated with lower academic performance at age 9 and weaker working memory at age 10.5. The results indicate that when children use screens may matter as much as how long they spend using them. The World Health Organization (WHO) and the American Academy of Pediatrics advise avoiding screens before 18 to 24 months and limiting viewing to less than one hour per day between ages 2 and 5. Many children exceed those recommendations, yet previous research on screens and cognitive development has produced inconsistent results. The analysis included 502 children followed from infancy into middle childhood. Higher screen viewing during particular stages was associated with poorer academic results and weaker working memory later on. The clearest and most consistent relationships appeared during infancy and near school entry, suggesting that these may be especially sensitive periods for cognitive development. Children with greater total screen exposure across childhood also generally performed less well in school. Together, the findings suggest that both the timing and overall amount of viewing may have implications for learning and memory. Some caffeinated drinks are linked to poorer memory Applied Science

Gary reads the second part of his latest essay - How to Manifest Your Authentic Self and the latest on Health and Healing. HEALTH NEWS Ancient grain sorghum shows potential against Alzheimer’s in early cell research Daily multivitamin improves functional health in older adults, study finds Kids who own cellphones have poorer reading comprehension scores than those who don’t, researchers find Time-restricted eating may help retain cognitive function in older adults Exercise Rewires Heart’s Nerve Network in Left-Right Pattern Ancient grain sorghum shows potential against Alzheimer’s in early cell researchEdith Cowan University & Alzheimers Research Australia, July 27 2026 (Natural News) Sorghum polyphenols reduced toxic amyloid-beta buildup in brain cells by up to 76 percent in a laboratory study. Scientists extracted polyphenols from three varieties of sorghum — black, red-brown and red — and exposed cultured human brain cells to amyloid-beta, the sticky protein long implicated in Alzheimer's plaque formation. Black sorghum showed the strongest protective effect on cultured human brain cells. Treated cells had over 70 percent better survival and 80 percent more active mitochondria. The findings still require animal studies before any health claims. Sorghum is gluten-free, fiber-rich, and loaded with the same class of plant compounds found in berries, olive oil, tea and dark chocolate — nutrients researchers have long connected to healthier brain aging. Daily multivitamin improves functional health in older adults, study finds Medical College of Georgia at Augusta University, July 27 2026 (News-Medical) The ability to perform everyday activities free of debilitating symptoms profoundly affects quality of life as we age. In a new study, older adults who took a daily multivitamin had significantly better measures of functional health after 3 years compared with those who took a placebo. According to researchers, the findings suggest a daily multivitamin can help older people maintain day-to-day functioning by helping to preserve cognitive abilities, and it may also benefit blood circulation and physical stamina. The researchers analyzed data from over 16,000 people aged 60 years and older. Participants were randomly assigned to take a daily multivitamin, a cocoa extract supplement, both or neither, with placebos used for the control group and for those taking only one supplement. After 3 years, participants taking a multivitamin had significantly better functional health than those taking a placebo. Kids who own cellphones have poorer reading comprehension scores than those who don’t, researchers find University of California at Los Angeles, July 27 2026 (Eurekalert) The widespread concern about the effect of cellphones on reading comprehension in elementary school children has led to surprisingly little experimental research. New research by UCLA psychologists found a statistically significant relationship between owning a cellphone and lower reading scores — children who owned cellphones had poorer reading comprehension than those who did not. This negative relationship between phone ownership and reading scores held for students who spoke English at home and those who did not. In fact, simply owning a phone correlated with worse reading comprehension, whether or not the phone was brought to school. Time-restricted eating may help retain cognitive function in older adults Rutgers University, July 27 2026 (Medical Xpress) Results from a small clinical trial suggest it may be possible to reduce the risk of dementia by eating during fewer hours of the day. The pilot study, which involved a weight-loss program for older women with overweight or obesity, showed modest cognitive improvements among those who limited their daily eating window instead of just reducing their calorie intake. The trial enrolled 47 women ages 50–79 who were overweight or obese. All participants were counseled to reduce their calorie intake by 500 calories per day. Twenty-six participants were asked to restrict their eating to a window of less than nine hours per day, while the rest maintained a typical eating window of about 12 hours per day. In the time-restricted eating group, participants generally ate only between 10 a.m. and 6 p.m., with an average daily eating window of 8.2 hours, compared with an average of 12.3 hours per day among those asked to maintain the standard eating window.

HEALTH NEWS Berberine Shows Beneficial Effects on Metabolic Health, Study Reports Cooperation beats selfishness more often than scientists thought Sleep Disorders Don’t Just Exhaust You. New Research Shows They Change Your Brain Two Hours of Strength Training Weekly Linked to Lower Heart Attack Risk in Women, Study Finds Planetary Health Diet lowers cardiovascular risk in older women Berberine Shows Beneficial Effects on Metabolic Health, Study Reports Peking Union Medical College (China), July 24 2026 (Natural News) A review published in the journal Molecules has summarized evidence indicating that berberine, a compound found in several plants, may influence glucose and lipid metabolism. According to the review, berberine has been associated with improvements in metabolic health markers across multiple studies. The compound is a yellow alkaloid extracted from plants such as European barberry, goldenseal, goldthread, Oregon grape, and tree turmeric. The review cited evidence that berberine may reduce blood glucose levels and improve insulin sensitivity, according to clinical trials. A systematic review of seven randomized clinical trials from China published in Nutrients revealed that berberine consistently alters the composition of gut bacteria in patients taking the supplement, and the analysis examined data across conditions including Type 2 diabetes, high cholesterol, and colorectal adenoma. Lipid panel improvements, including lower total cholesterol and triglycerides, were also reported in the reviewed studies. Cooperation beats selfishness more often than scientists thought Hebrew University of Jerusalem & Rutgers University, July 20 2026 (Eureaklert) For decades, one of the most influential ideas in evolutionary biology has suggested that when individuals act purely in their own self-interest, cooperation should eventually collapse. But a new study by the Hebrew University of Jerusalem and Rutgers University demonstrates that evolution may be far more optimistic than previously believed. Their findings reveal that cooperation does not require close family ties, reputation, repeated favors, or rigid social structures. Instead, cooperation can flourish simply because individuals respond differently to different opponents. The research proposes a new solution to one of biology's oldest puzzles: how cooperation survives in a world shaped by natural selection. Using mathematical models, evolutionary simulations, and populations of artificial intelligence agents, the researchers found that cooperation consistently evolved when individuals adjusted their willingness to cooperate according to whom they encountered. Rather than treating everyone identically, simple opponent-specific responses created stable communities in which cooperative behavior repeatedly outperformed purely selfish strategies. Perhaps the study's most surprising finding is that cooperative societies are not fragile exceptions. Across thousands of simulations, populations repeatedly evolved toward highly cooperative states, while purely selfish populations often failed to dominate. Even when mutations introduced new defectors, cooperative communities remained remarkably resilient. Sleep Disorders Don’t Just Exhaust You. New Research Shows They Change Your Brain Florida International University, July 26, 2026 (SciTech Daily) A poor night’s sleep can affect far more than energy the next day. Research from Florida International University links sleep disorders with structural differences in brain regions that help control attention, motivation and decision-making. Published in the journal Scientific Reports, the findings provide one of the broadest comparisons yet of how different sleep disorders are associated with the brain. The researchers compared two broad categories. Dyssomnias, such as insomnia and sleep apnea, interfere with falling asleep or remaining asleep. Parasomnias, including sleepwalking, nightmare disorder and sleep terrors, involve unusual events that disrupt the sleep cycle. Both categories were associated with decreases in the thalamus, a region that filters incoming information, supports concentration, and contributes to higher-level thinking. The researchers identified changes specifically in the pulvinar, an area within the thalamus that directs attention and helps manage cognitive control. These differences were connected with wider brain networks that support concentration and task performance. That pattern may help explain why disrupted sleep is associated with slower reactions, poorer decision-making and a greater likelihood of errors and accidents.

HEALTH NEWS Curcumin shows the best balance against cancer, study shows First trial confirms swimming reduces disability from chronic back pain Nanoplastics in Drinking Water May Be Making Dangerous Bacteria Stronger, New Study Warns Kids remember veggie scents from womb, study finds Watermelon Contains Compounds Linked to Cardiovascular and Metabolic Health, Studies Show Curcumin shows the best balance against cancer, study shows Wroclaw Medical University (Poland), July 22 2026 (News-Medical) Curcumin, berberine, and other plant-derived compounds have long attracted scientific interest because of their anti-inflammatory and anticancer properties. A new study by researchers from Wroclaw Medical University, however, shows that not all natural compounds act in the same way, and strong anticancer activity does not always go hand in hand with a good safety profile. The researchers compared five compounds: curcumin, berberine, biochanin A, cucurbitacin E, and CAPE (caffeic acid phenethyl ester), a component of propolis. They investigated how these substances affected fibrosarcoma cells and healthy muscle cells. The study focused on the NF-κB signaling pathway, which regulates inflammation, metabolism, cell survival, and cellular aging. The tested compounds disrupted mitochondrial function, reducing the cancer cells’ ability to produce energy. In fibrosarcoma cells, ATP levels decreased by approximately 83–92%, compared with reductions of around 23–73% in healthy muscle cells. This suggests that cancer cells are more vulnerable to disturbances in energy metabolism. The compounds also affected mitophagy, the process responsible for removing damaged mitochondria. All five compounds induced features of cellular senescence in fibrosarcoma cells. In this state, cells remain alive but permanently lose their ability to divide. The strongest effect was observed with curcumin. The proportion of senescent cancer cells increased from approximately 16.5% to more than 75%. For the other compounds, the percentage exceeded 66% as well. Healthy muscle cells generally showed a weaker response, suggesting a degree of selectivity towards cancer cells. First trial confirms swimming reduces disability from chronic back pain Macquarie University, July 21 2026 (Eurekalert) Australian research has shown for the first time that a program of swimming can be clinically effective in reducing disability from chronic low back pain. Publishedin the British Journal of Sports Medicine, the clinical trial found an eight-week individualised program of swimming and education, guided by a physiotherapist, improved function and pain significantly more than education alone in people with back pain. The researchers recruited 76 adults aged 26 to 74 (average 41 years) who were experiencing some disability due to low back pain lasting for at least 12 weeks and allocated them at random to one of two groups. One group received an eight-week individualised program of swimming and education, supported by four telehealth coaching sessions with a physiotherapist. They weren’t regular swimmers, but they were able to swim 25 metres and feel confident in the water. The swimming programme was based on a goal of achieving three sessions of 30-45 minutes by the end of the eight weeks. After eight weeks, disability was significantly lower in the swimming group. They improved by about 50 per cent from where they were before starting the program. Compared to the control group who received education only, swimmers scored on average 2.5 points or 30 per cent lower on a widely used disability scale. Nanoplastics in Drinking Water May Be Making Dangerous Bacteria Stronger, New Study Warns Virginia Tech University, July 21 2026 (Natural News) A study published in the journal Water Research found that nanoplastics, tiny plastic particles invisible to the naked eye, can increase the mechanical strength of bacterial biofilms and make them more resistant to disinfectants. The research, conducted by Virginia Tech and an international team, examined how these particles affect microbial communities inside drinking water systems. The findings indicate indirect public health risks through water systems. The nanoplastics can make the antimicrobial-resistant pathogens better survive, which could be harmful to the environment and would have public health implications. The study focused on biofilms containing E. coli and Pseudomonas aeruginosa, two bacteria commonly associated with waterborne infections. When exposed to nanoplastics, the bacteria activated multiple defense mechanisms, resulting in thicker, heavier biofilms. These strengthened biofilms pose a greater challenge for water treatment facilities, according to the researchers. Biofilms are commu

HEALTH NEWS Analysis of 82 Trials Shows Black Seed May Improve Cardiovascular Risk Markers New Study Reveals Herpesvirus Infection May Accelerate Alzheimer’s Disease Favorable lifestyle factors reduce dementia risk across key genetic profiles People are living longer, but spending more years in poor health Imbalances in the oral microbiome linked to symptomatic hand osteoarthritis Analysis of 82 Trials Shows Black Seed May Improve Cardiovascular Risk Markers Shahid Beheshti University of Medical Sciences (Iran), July 21 2026 (Natural News) A pooled analysis of 82 randomized controlled trials involving 5,026 adults has found that supplementation with Nigella sativa, commonly known as black seed or black cumin, is associated with improvements in multiple cardiovascular risk markers. The meta-analysis, published in the journal Pharmacological Research, was conducted by researchers from several Iranian universities. The analysis used a GRADE-assessed, dose-response method to evaluate the effects of black seed compared with placebo or standard care. According to the study, black seed supplementation led to significant reductions in body weight, body mass index, waist circumference, and body fat percentage. The analysis noted that daily amounts used in most trials ranged from 1 to 3 grams of ground black seed or 1 to 3 milliliters of black seed oil. According to the researchers, one teaspoon of ground black seed contains roughly 4 grams, meaning a single daily teaspoon stirred into food falls within the range used in studies. For those who prefer oil, a half teaspoon delivers close to 2 milliliters. The researchers emphasized that consistency, rather than a large single dose, appears to drive positive results. New Study Reveals Herpesvirus Infection May Accelerate Alzheimer’s Disease Cardiff University (UK), July 21, 2026 (SciTech Daily) In a new study, researchers found that herpesvirus infection intensified memory problems and other Alzheimer’s-related changes in mice already vulnerable to the disease. The damage appeared to be driven not simply by the virus itself, but by the immune system’s prolonged attempt to control it. Herpesviruses are a large family that includes viruses associated with cold sores, childhood infections, and glandular fever. After the initial illness passes, some can remain dormant inside the body and reactivate later, repeatedly drawing the immune system into action. Scientists results suggest that T cells, immune cells that identify and attack infected cells, can enter the brain during herpesvirus infection and accelerate cognitive decline. Following infection, large numbers of immune cells moved into the brain. Most were CD8+ T cells that specifically recognized the virus, showing that they had entered the tissue as part of the body’s attempt to contain the infection. Similar T cells have previously been found in the brains and spinal fluid of people with Alzheimer’s disease, although their exact role has remained uncertain. The results indicate that a virus-driven immune response can actively speed the progression of Alzheimer’s-like disease rather than merely appearing alongside it. Favorable lifestyle factors reduce dementia risk across key genetic profiles Kyushu University (Japan), June 5 2026 (News-Medical) With dementia cases expected to nearly triple worldwide by 2050, researchers are increasingly focused on identifying ways to prevent or delay the disease. While lifestyle and health-related factors, such as blood pressure control and physical activity, influence dementia risk, genetics also play a major role. Currently, it is unclear if maintaining a favorable lifestyle reduces dementia risk equally across different genetic backgrounds. A new study led by Kyushu University examines whether favorable modifiable risk factors (mRF)-behaviors or conditions that people can change or control-can lower dementia risk even among individuals with high genetic susceptibility. The researchers analyzed data from 9,605 community-dwelling adults aged 65 and older. They determined each participant's APOE ε4 genotypes, a primary genetic risk factor for Alzheimer's disease, and calculated the mRF score based on lifestyle and health-related factors. This allowed the team to evaluate how genetic predisposition and lifestyle choices jointly interact to influence dementia risk. The results showed that dementia risk rose progressively with the number of APOE ε4 alleles. Notably, among individuals with one or no APOE ε4 alleles, maintaining a healthier profile with lower mRF scores was linked to a significantly lower risk of dementia. In contrast, among individuals with two APOE ε4 alleles, dementia risk did not differ significantly between those with lower and higher mRF scores. These
