Scientists raise red flag over effects of microscopic threat to vital organs: 'A potential health risk'
A new study on mice has highlighted the damage that ingested microplastics can cause to different organs.
What's happening?
Researchers assessed the toxicity of polystyrene microplastics to the gut and mammary glands in subject mice, according to the study, published in the journal Science of Food. The scientists found that the tiny plastic particles accumulated in various tissues, causing significant harm to the gut and mammary glands.
Specifically, they found that microplastics could "disrupt the intestinal barrier" and lead to inflammation of the colon and an imbalance of the gut microbiome. They also observed that microplastics can accumulate in mammary tissue, causing inflammatory damage there, among other effects.
"These findings indicate that ingestion of microplastics poses a potential health risk," the authors stated. "Further control of microplastics contamination in food is needed to promote public health and wellness."
Why are microplastics concerning?
The study added to a growing understanding and body of research about the health impacts of microplastics. For instance, a previous experiment on pigs discovered that microplastic exposure can trigger an inflammatory response in the enteric nervous system, which affects functions including immune responses.
The effects of microplastics on human health are still being explored. But other studies have linked microplastic exposure to health problems such as cancer, dementia, and impaired blood flow in the brain.
What's being done about microplastics?
Though microplastics pollute soil, water, food, and air, scientists are discovering new ways to remove them from our environment. For instance, one team found a way to get them out of soil by using a type of processed farm waste.
You can help reduce the amount of microplastics entering the environment, and reduce your own exposure, by opting for plastic-free alternatives to everyday products. Choose reusable bottles and containers instead of single-use varieties, for instance.

Metformin May Shield Against Dementia in Overweight/Obesity
TOPLINE: During a 10-year follow-up, metformin use was associated with significantly lower risks for both dementia and all-cause mortality in patients with overweight or obesity. METHODOLOGY: Metformin, the most widely prescribed glucose-lowering treatment, is linked to a reduced risk for dementia in patients with diabetes; however, its effect on the incidence of dementia among individuals with obesity has not been established with real-world data. Researchers analyzed data from adults with varying degrees of overweight and obesity from a popular global health research network to investigate the link between metformin and the long-term incidence of dementia and all-cause mortality. Adults prescribed metformin at least twice, with a minimum of 6 months between prescriptions, were compared with propensity score-matched control individuals who did not receive the medication; the follow-up period was 10 years. In both the metformin and control groups, the number of participants was 132,920 for BMI 25-29.9; 142,723 for BMI 30-34.9; 94,402 for BMI 35-39.9; and 82,732 for BMI ≥ 40. The primary outcomes measured were dementia and all-cause mortality. TAKEAWAY: After 10 years of follow-up, metformin users had a significantly lower risk for dementia across BMI categories than control individuals (hazard ratio [HR] for BMI 25-29.9, 0.875 [95% CI, 0.848-0.904]; HR for BMI 30-34.9, 0.917 [95% CI, 0.885-0.951]; HR for BMI 35-39.9, 0.878 [95% CI, 0.834-0.924]; and HR for BMI ≥ 40, 0.891 [95% CI, 0.834-0.953]). All-cause mortality was also reduced in metformin users, with HRs ranging from 0.717 to 0.743 across all BMI categories. Age-stratified analysis showed that among patients younger than 65 years, metformin may significantly reduce the risk for dementia for those with BMIs of 30-39.9. IN PRACTICE: 'Regarding the relationship between metformin, dementia, and all-cause mortality, our findings suggest that metformin not only has a protective effect against dementia but also significantly reduces all-cause mortality. Since dementia is a contributing factor to all-cause mortality, this may partially explain metformin's effect,' the authors wrote. SOURCE: This study was led by Yu-Liang Lin, MD, Taipei Medical University, Taipei, Taiwan. It was published online on August 6, 2025, in Diabetes, Obesity and Metabolism. LIMITATIONS: The use of standard diagnostic codes for dementia diagnosis may have contributed to potential misclassification in real-world settings. Due to confidentiality agreements, researchers could not access raw and individualized data, and treatment escalation sequences were unknown. The effects of changes in medication regimens after the second metformin prescription could not be determined. DISCLOSURES: This study did not report any source of funding. The authors declared having no conflicts of interest. This article was created using several editorial tools, including AI, as part of the process. Human editors reviewed this content before publication.

The Best and Worst Chest Exercises, According to a Trainer
The Best and Worst Chest Exercises, According to a Trainer originally appeared on Men's Fitness. Chest day is sacred. But if you're just benching and hoping for the best, you're leaving serious gains on the table. Your chest is a complex group that responds differently depending on the angle, grip, and tool you use—not just a flat slab of muscle. In this guide, we're breaking down the most popular chest exercises from the best to the ones you could probably ditch, while also telling you what part of your chest each one targets. That way, you're training hard, training with intent, and most importantly, training smart. We also included training tips, rep/set guidelines, and movement classifications to help you program with purpose.A Quick Chest Anatomy Primer Your chest contains two main muscles: Pectoralis Major: The large, fan-shaped muscle most guys think of when they hear 'pecs.' It has: Clavicular head (upper chest) Sternal head (middle and lower chest) Pectoralis Minor: A smaller muscle underneath that helps stabilize and control scapular movement. While you can't completely isolate 'inner' or 'outer' pecs, you can emphasize specific regions based on: Bench angle Arm path Grip width Resistance type (free weights vs. machines) The Best Chest Exercises These are the foundational lifts that should anchor your chest training. They build mass, strength, and symmetry across multiple regions of the chest. 1. Barbell Bench Press The benchmark of upper-body strength. You can load it heavily, progress easily, and recruit large amounts of muscle. A slightly wider grip emphasizes the pecs over the triceps. Primary Target: Middle Chest Secondary: Front delts, triceps Type: Compound Sets/Reps: 4 sets of 5 to 8 reps 2. Incline Dumbbell Press Incline pressing with dumbbells builds the upper chest and allows for a deeper stretch than barbells. The independent arms also allow for better pec contraction and shoulder safety. Primary Target: Upper Chest Secondary: Front delts, inner chest Type: Compound Sets/Reps: 3 to 4 sets of 8 to 12 reps 3. Cable Chest Flyes Cables provide constant tension, especially at the top of the rep, where dumbbells tend to lose tension. They're ideal for targeting the squeeze and building that deep line down the center of the chest. Primary Target: Inner and Middle Chest Secondary: Front delts Type: Isolation Sets/Reps: 3 to 4 sets of 12 to 15 reps 4. Weighted Dips (Chest Lean) When you lean forward and flare your elbows, dips become a brutal chest exercise. They allow for a massive range of motion and can be loaded with plates or a belt. Primary Target: Lower Chest Secondary: Triceps, front delts Type: Compound Sets/Reps: 3 sets of 6 to 10 reps 5. Machine Chest Press (Hammer Strength or Plate Loaded) The machine chest press eliminates stabilizers from the equation, allowing you to focus on pure chest output. Great for hypertrophy and high-volume work after barbell or dumbbell sets. Primary Target: Whole Chest (slightly middle-biased) Secondary: Triceps Type: Compound (guided) Sets/Reps: 3 to 4 sets of 8 to 12 reps The Average Chest Exercises These aren't bad. They can still build muscle, but they either limit range of motion, don't target the chest directly, or have better alternatives. 6. Push-Ups A great beginner tool or burnout finisher. But without added resistance, it won't get you far in terms of hypertrophy unless you're doing high-rep sets or advanced progressions. Primary Target: Middle Chest Secondary: Triceps, shoulders, core Type: Compound Sets/Reps: 3 to 4 sets to failure or 15 to 25 reps 7. Pec Deck / Machine Flyes Delivers a solid contraction but limits the stretch. Great for pump work or drop sets, but less effective for mass-building compared to cable or dumbbell flyes. Primary Target: Inner Chest Secondary: Minimal Type: Isolation Sets/Reps: 3 sets of 12 to 15 reps 8. Decline Barbell Press While it can overload the lower pecs, it often becomes triceps-dominant. Many lifters also experience awkward shoulder positioning, and some benches don't accommodate proper leg drive. Primary Target: Lower Chest Secondary: Triceps Type: Compound Sets/Reps: 3 sets of 6 to 10 reps 9. Flat Dumbbell Press Still effective, but often gets overshadowed by the barbell version. Requires more stabilization and control, so the potential for strength is lower. Great for hypertrophy, though. Primary Target: Middle Chest Secondary: Front delts, triceps Type: Compound Sets/Reps: 3 to 4 sets of 8 to 12 reps The Below-Average Chest Exercises These are either outdated, misused, or just less effective than the alternatives. They're not useless, but they shouldn't be your go-to moves. 10. Dumbbell Pullover Historically thought of as a chest expander, but most of the stretch and load is felt in the lats. Some benefit from it, but most use it as a filler rather than a chest builder. Primary Target: Questionably chest; often lats Secondary: Lats, triceps Type: Hybrid Sets/Reps: 2 to 3 sets of 12 to 15 reps 11. Guillotine Press Popularized by old-school bodybuilders, this movement puts excessive stress on the shoulders and neck. The risk-to-reward ratio is just too high for most lifters. Primary Target: Upper Chest Secondary: Shoulders Type: Compound Sets/Reps: Not recommended 12. Standing Plate Press (Svend Press) The plate's weight and size limit you, and most of the burn is from isometric tension, not dynamic overload. It can be a burnout move, but there are better options. Primary Target: Inner Chest (mildly) Secondary: Front delts Type: Isometric / Isolation Sets/Reps: 2 to 3 sets of 15 to 20 reps Chest Training Tips for Maximum Growth Want to get more out of your chest workouts? Apply these principles to create a more complete and visually appealing chest. 1. Train Chest 1–2 Times Per Week Hit your chest at least once a week with high intent. For optimal growth, train it twice—once focusing on strength and once on volume and hypertrophy. 2. Prioritize Based on Weak Points Lacking upper chest? Start with incline movements. Want more inner chest? Use cable or pec deck flyes and focus on squeezing at the top of the movement. Trying to carve out the lower pec shelf? Incorporate dips or decline work near the end of your session. 3. Use Multiple Angles A flat bench isn't enough. Rotate incline, decline, and slight incline variations to challenge the muscle fibers from different angles. 4. Control the Eccentric Most lifters rush the lowering phase. Slow it down (2–3 seconds) to increase muscle tension and reduce momentum. 5. Limit Shoulder Domination If you feel your shoulders doing all the work, adjust your elbow angle. Tuck slightly and flare at a 45-degree angle to keep the chest engaged and joints safe. Final Word Chest training stands on the principle of how effectively you're loading the muscle. Prioritize proven compound lifts, such as the bench press, incline dumbbell presses, and cable flyes. Rotate in isolation work for mind-muscle connection, and skip the fluff that doesn't deliver. Train every region of your chest, program with intent, and you'll build a chest that's as strong as it Best and Worst Chest Exercises, According to a Trainer first appeared on Men's Fitness on Jul 9, 2025 This story was originally reported by Men's Fitness on Jul 9, 2025, where it first appeared.

Breakthrough study finds deficiency of this common nutrient could contribute to Alzheimer's
A deficiency of the metal lithium in the body could be a key factor contributing to the development of dementia in Alzherimer's patients, a groundbreaking new study reveals. The decade-long research, published in the journal Nature, shows for the first time that lithium occurs naturally in the brain and maintains the normal function of all its major cell types, preventing nerves from degradation. Scientists from Harvard Medical School found that lithium loss in the human brain is one of the earliest changes leading to Alzheimer's, while in mice, a similar lithium depletion accelerated memory decline. A reduced lithium level was found in some cases due to the metal's impaired uptake and its binding to amyloid plaques, which are known to be smoking gun signs of Alzheimer's. Researchers also showed that a new type of lithium compound – lithium orotate – can avoid capture by amyloid plaques and restore memory in mice. In the study, scientists used an advanced type of mass spectroscopy chemical analysis method to measure trace levels of about 30 different metals in the brain and blood samples from a range of people, including cognitively healthy people, those in an early stage of dementia, and those with advanced Alzheimer's. The analysis revealed that lithium was the only metal with markedly different levels across groups, which also seemed to change at the earliest stages of memory loss. 'Lithium turns out to be like other nutrients we get from the environment, such as iron and vitamin C,' study senior author Bruce Yankner said. 'It's the first time anyone's shown that lithium exists at a natural level that's biologically meaningful without giving it as a drug,' Dr Yankner said. Although lithium compounds have been historically in use to treat a range of mental conditions like bipolar disorder and major depressive disorder, in these cases, they are given at much higher concentrations that could even be toxic to older people. Scientists have now found that lithium orotate is effective at one-thousandth this dose – enough to mimic the natural level of lithium in the brain. The latest findings with lithium orotate, however, needs to be confirmed in humans via clinical trials. Yet, researchers suspect that measuring lithium levels could help screen people for early Alzheimer's. The findings revise the theory of Alzheimer's disease, which affects nearly 400 million people worldwide, offering a new strategy for early diagnosis, prevention, and treatment. Decades of studies have shown that Alzheimer's disease involves an array of brain abnormalities, including clumps of the protein amyloid beta, tangles of the protein tau, and a loss of the brain's protective protein REST. However, these abnormalities have never fully explained the condition. For instance, it remains unclear why some people with Alzheimer's-like changes in the brain never go on to develop dementia or cognitive decline. Recent treatments developed to target amyloid beta plaques also don't seem to reverse memory loss, only modestly reducing the rate of cognitive decline. Now, scientists say lithium could be the critical missing link. 'The idea that lithium deficiency could be a cause of Alzheimer's disease is new and suggests a different therapeutic approach,' Dr Yankner said. 'You have to be careful about extrapolating from mouse models, and you never know until you try it in a controlled human clinical trial... But so far the results are very encouraging,' he added.
