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.

Surprisingly, summer sunshine did not significantly boost vitamin D levels among older adults or people from minoritized ethnic backgrounds. Wed, 24 Jun 2026 00:45:50 EDT https://www.sciencedaily.com/releases/2026/06/260623083104.htm https://www.sciencedaily.com/releases/2026/06/260605023408.htm Supplements are often marketed as shortcuts to better health, but for many older adults, the real issue is whether they have a specific deficiency. Vitamins like B12 and D can play an important role when levels are low, while protein may be one of the most overlooked nutrients for maintaining strength and independence. More isn’t always better, though—some supplements can cause harm or interact with medications.

In a small study, women who took low doses alongside treatment were far more likely to see their cancer vanish than those who didn’t. Since vitamin D also supports immune function—and many patients are deficient—it could be playing a bigger role than expected. Scientists say this affordable approach deserves much deeper investigation.

Researchers found that people who eat more fruits and vegetables known to carry higher pesticide residues—such as strawberries, spinach, and bell peppers—also have significantly higher levels of those chemicals in their urine. While produce remains a cornerstone of a healthy diet, the findings highlight how everyday food choices can drive real-world exposure to substances linked to cancer, hormone disruption, and developmental harm.

The protein senses physical activity and pushes bone marrow stem cells to build bone instead of storing fat, slowing age-related bone loss. By targeting this “exercise sensor,” scientists believe they could create drugs that mimic exercise at the molecular level. The approach could protect fragile bones in people who are unable to stay active.

The study found that magnesium raised vitamin D in people who were deficient while dialing it down in those with overly high levels—suggesting a powerful regulating effect. This could help explain why vitamin D supplements don’t work the same way for everyone and why past studies linking vitamin D to cancer and heart disease have produced mixed results.

Researchers discovered that combining radiation with immunotherapy can transform stubborn, unresponsive lung tumors into targets for immune attack—especially those considered “cold” and typically resistant. This happens through a rare and poorly understood effect where immune cells are activated systemically, not just at the radiation site. Patients whose tumors underwent this “warm-up” had significantly better outcomes, revealing a promising new strategy for fighting hard-to-treat cancers.

Researchers found that disabling this gene in colorectal cancer cells not only crippled their survival but also disrupted thousands of other genes tied to cancer and metabolism. This opens the door to highly targeted cancer therapies—by either cutting off vitamin D supply to tumors or enhancing the gene’s activity to boost health. The findings hint at vast possibilities in treating diseases influenced by vitamin D, though long-term impacts remain uncertain.

If global temperatures rise by 3.5 C by 2100, 92% of children born in 2020 will experience unprecedented heatwave exposure over their lifetime, affecting 111 million children. Meeting the Paris Agreement's 1.5 C target could protect 49 million children from this risk. This is only for one birth year; when instead taking into account all children who are between 5 and 18 years old today, this adds up to 1.5 billion children affected under a 3.5 C scenario, and with 654 million children that can be protected by remaining under the 1.5 C threshold.

Drawing from a large database of genetic information, they gathered dozens of sequenced genomes from people with rheumatoid arthritis and osteoporosis to look for any similarities, using recently developed computational methods to narrow down their search. They identified genes ATXN2L and MMP14 as significantly associated with the progression of both rheumatoid arthritis and osteoporosis.
