Because it develops silently, many people only discover they have it after a fracture or bone scan. Aging, menopause, poor diet, and inactivity can all contribute to bone loss. Fortunately, exercise, adequate calcium and vitamin D, and other healthy habits can slow or even partially reverse the decline. Thu, 25 Jun 2026 00:25:26 EDT https://www.sciencedaily.com/releases/2026/06/260624025511.htm https://www.sciencedaily.com/releases/2026/06/260623083116.htm Vitamin B12 is needed in microscopic amounts, but a shortage can have major effects on health and energy. The vitamin was first linked to a lifesaving liver treatment for pernicious anemia nearly 100 years ago. Today, researchers are finding that B12 may also help keep cellular powerhouses called mitochondria functioning properly. This could explain why some people experience fatigue and brain fog even before traditional signs of deficiency show up.

Studying nearly 7 million cells, they found that aging starts earlier than expected and unfolds in a coordinated way throughout the body. About a quarter of cell types change in number over time, and many of these shifts differ between males and females. The research also highlights shared genetic “hotspots” that could become targets for anti-aging therapies.

New projections from the American Heart Association warn that over the next 25 years, cardiovascular disease will rise sharply, driven largely by a surge in high blood pressure, diabetes, and obesity. By 2050, nearly 60% of women in the U.S. could have high blood pressure, and close to one in three women ages 22 to 44 may already be living with some form of heart disease.

In very old age, staying strong and maintaining muscle matters more than long-term disease prevention. Older adults who included fish, eggs, or dairy were just as likely to become centenarians as meat eaters, suggesting that key nutrients may make the difference. The takeaway: nutrition needs change dramatically with age.

In a study of more than 700 women, those who felt more anxious about aging showed signs of faster biological aging in their blood, measured using cutting-edge “epigenetic clocks.” Fears about declining health had the strongest link, while concerns about beauty or fertility didn’t appear to have the same biological impact.

In a large national study of more than 3,800 Americans age 70 and older, those who received the shingles vaccine showed slower biological aging compared to those who didn’t. Researchers found lower levels of chronic inflammation and slower changes in gene activity linked to aging, suggesting the vaccine may calm the body’s “inflammaging” — the low-grade inflammation tied to heart disease, frailty, and cognitive decline.

This protein, NDRG1, acts like a brake, preventing cells from activating quickly after injury. When researchers blocked it in older mice, muscle healing sped up dramatically — but stem cells became less resilient over time. The work suggests aging may reflect a survival trade-off rather than straightforward decline.

Researchers found that boosting DMTF1 can restore the ability of neural stem cells to regenerate, even when age-related damage has set in. Without it, these cells struggle to renew and support memory and learning. The findings raise hopes for treatments that could slow or even reverse aspects of brain aging.

Polygonum multiflorum, long believed to restore dark, healthy hair, appears to work on multiple fronts at once—blocking hair-shrinking hormones, protecting follicles from damage, activating natural regrowth signals, and boosting blood flow to the scalp.

Brain scans revealed grey matter loss in areas tied to memory and emotional regulation, while many women reported increased anxiety, depression, and fatigue. Hormone therapy did not reverse these effects, though it may slow age-related declines in reaction speed. Researchers say menopause could represent an important turning point for brain health.

Researchers found that cells actively remodel a key structure called the endoplasmic reticulum, reducing protein-producing regions while preserving fat-related ones. This process, driven by ER-phagy, is tied to lifespan and healthy aging. Because these changes happen early, they could help trigger later disease—or offer a chance to stop it.

A large study tracking more than 300,000 adults found that middle-aged and older night owls had poorer overall heart health and a higher risk of heart attack and stroke than those who were active earlier in the day, with the effect especially pronounced in women. Much of this elevated risk appeared to stem from lifestyle factors common among evening types, including smoking and inadequate sleep.

Researchers found that SGLT2 inhibitors, widely used to treat diabetes and heart disease, preserved kidney structure, blood vessels, and energy production as the fish aged, while also calming inflammation. The results help explain why these drugs protect kidneys and hearts so reliably in people, even beyond blood sugar control.
