A recent study reveals that Phaeocystis antarctica, an algae native to the Southern Ocean, can thrive without vitamin B12, challenging previous assumptions. This discovery, indicating the algae’s adaptability to B12 scarcity through a unique gene, has implications for Antarctic ecosystems, climate change models, and future research on algae’s survival strategies in changing environments.Vitamin B12 deficiency can lead to serious and potentially deadly health issues in humans. Until now, the same deficiencies were thought…

A groundbreaking study reveals a novel molecular link between vitamin B12 and multiple sclerosis (MS), focusing on astrocytes in the brain. The research demonstrates that fingolimod, an FDA-approved MS drug, can regulate B12 communication pathways, highlighting the potential for B12 supplementation in MS treatment. Credit: SciTechDaily.com Findings identify molecular signaling pathway that could enhance current MS treatments. For decades, scientists have noted an intriguing similarity between a deficiency in vitamin B12…

It’s well documented that vitamin B12, or cobalamin, helps red blood cells form and facilitates DNA synthesis that protects genetic mutations in our cells. It is also crucial in the development and ongoing function of our brain and nerve cells. Now, scientists have found that this micronutrient also plays a key role in cellular reprogramming and tissue regeneration.IRB Barcelona researchers discovered this new set of biological tricks while observing how the process of cellular reprogramming in mice required an enormous…

Following treatment and the end of his nitrous oxide use, the man did eventually regain the function of his legs. But the medical tale is perhaps a timely reminder of why states like New York have recently decided to ban the sale of industrial-strength whipped cream chargers that contain the gas to teens.The case study was published last week in the New England…

Vegan and vegetarian diets are certainly trendy, with more people than ever before making the switch. While some people are choosing to go plant-based for environmental reasons, others are adopting these diets because of their health benefits.  It's hardly surprising, given studies have linked vegetarian and vegan diets to a lower body mass index (BMI) and a lower risk of certain diseases – including cancer, type 2 diabetes, and heart disease.But while plant-based diets may have many health benefits, they can, without…
