In 2025, Jingfeng Chen and a team from Chinese universities reviewed animal and human studies on how vitamin D and exercise together help keep brains healthy as people age. They looked at things like brain growth proteins, blood flow, and swelling in the brain, focusing on older adults with memory problems.

In 2025, Elena Freire Paz and a team from the University of Santiago de Compostela studied 25 older adults in Spain (Galicia and Extremadura) using interviews and home observations from November 2024 to April 2025. They explored how loneliness affects eating habits, focusing on food choices, cooking routines, and meal enjoyment.

In 2025, Vladimir Losev and a team from the MRC Laboratory of Medical Sciences in London analyzed 21,241 UK Biobank adults, using AI to study body fat via whole-body imaging and heart health through scans. They focused on visceral fat (hidden around organs like the stomach) and its link to heart aging, measured by tissue stiffness and inflammation.

In 2025, Takuji Kawamura and a team from Tohoku University reviewed studies on how exercise affects epigenetic aging, which shows how fast your body ages at the DNA level. They looked at human and animal research, focusing on structured workouts like running or weightlifting, using epigenetic clocks to measure DNA changes in blood, muscles, and other organs.

In 2025, Anni Vanhatalo and a team from the University of Exeter studied 24 older adults (aged 60-75) in a 2-week trial. Participants drank nitrate-rich beetroot juice (140 mL/day, ~400 mg nitrate) or a placebo juice, and researchers measured blood pressure, oral bacteria, and blood vessel health using standard tests.

In 2025, Fajian Ren and a team from Chengdu University of Traditional Chinese Medicine reviewed how flavonoids from safflower, like chalcones and quercetin, work in the body. They looked at many studies on these compounds, found in safflower petals used in traditional medicine for blood flow and pain relief.

In 2025, researchers from Anglia Ruskin University and Cambridgeshire and Peterborough NHS Foundation Trust ran a pilot program called MELODIC on two hospital wards for people with dementia. They brought in a music therapist to lead sessions and make custom music plans for each patient, aiming to prevent and handle tough emotions without always using meds.

A 2025 study in Frontiers in Nutrition by Wen et al. found that low handgrip strength (HGS) and low relative handgrip strength (RHGS) were strongly linked to increased odds and risk of asthma—by up to 50% for those at the lowest quartile of grip strength.

A 2025 review in Nutrients by Zhang dives into the crucial roles selenium plays in our bodies. As a key part of selenoproteins, this micronutrient helps balance redox reactions, regulate cell growth, support the immune system, and guard against DNA damage, chronic inflammation, insulin resistance, and neurodegeneration.

A 2025 randomized controlled trial in Nutrients by Sharif et al. showed those who drank tocotrienols experienced better psychological well-being, lowered markers of oxidative stress, increased antioxidant enzymes, and improved genomic stability.

Researchers at Tokyo Metropolitan University (2025) have unveiled a label-free technique using electric fields to pinpoint aged (senescent) human cells. By monitoring how skin cells respond to alternating electric fields, they can now identify cellular aging fast and without harmful dyes.
