Researchers at the University of Cambridge have developed embryo-like structures called hematoids from donated human stem cells that can produce red and white blood cells in the lab, potentially supplementing blood donations and advancing treatments for blood disorders. These structures mimic early human blood development and are more self-sustaining than previous methods, marking a significant step toward regenerative therapies.
A large vaccine study found that COVID vaccines from Pfizer, Moderna, and AstraZeneca are linked to rare occurrences of heart, brain, and blood disorders, including myocarditis, pericarditis, blood clots in the brain, Guillain-Barre syndrome, and other conditions. While the study identified increased risks, experts emphasize that the benefits of vaccination still outweigh the risks, especially compared to the potential risks of contracting COVID-19.
A viral TikTok video has brought attention to the phenomenon of "anemia lips," where the condition can strip natural pigment from the lips, causing them to appear pale. Anemia, a common blood disorder affecting over 3 million people in the US, can be caused by various factors such as iron deficiency, vitamin deficiency, aplastic anemia, hemolytic anemia, and sickle cell anemia. Pale lips, along with other symptoms like dizziness and weakness, can indicate low hemoglobin levels. Treating the underlying cause of anemia, such as through blood transfusions or supplements, can help restore the natural pigment to the lips and improve overall health.
