Newly Discovered Cell Type : EndoMac Progenitor
Scientists at the South Australian Health and Medical Research Institute have identified a new type of cell, called EndoMac progenitors, with the potential to enhance tissue repair and regeneration. These cells can transform into endothelial cells, which form blood vessels, and macrophages, which aid in tissue repair and defence. Discovered in adult mice, EndoMac progenitors respond to injury or poor blood flow by expanding rapidly to promote healing. Their unique ability to boost healing in diabetic wound models is particularly promising, as they could one day become a key tool in treating chronic wounds. Additionally, these cells don’t express typical immune markers, making them less likely to be rejected during stem cell transplantation. Researchers are now exploring their use in human tissue and are hopeful for future breakthroughs.

World’s Oldest Cheese Shows the Origin of Kefir
Researchers have uncovered the oldest known cheese, dating back 3,600 years, alongside mummies in China’s Tarim Basin. DNA analysis of the ancient cheese suggests it was kefir, a fermented dairy product, and sheds light on the evolution of probiotic bacteria. This discovery challenges the belief that kefir originated solely in the North Caucasus, instead pointing to the Xinjiang region of China as an early site of kefir culture. The study also reveals how the bacteria used in ancient kefir evolved to become more adapted to humans over thousands of years, offering a glimpse into ancient diets and lifestyles.

The Human Heart Ages Quickly After One Month in Space
Engineered human heart tissue sent to the International Space Station (ISS) showed signs of weakening, irregular beating, and molecular changes within just one month, mimicking the aging process. These findings, published in Proceedings of the National Academy of Sciences, reveal how space flight can significantly impact heart health. Using a “heart-on-a-chip” system, researchers tracked tissue contraction and genetic shifts in real-time, offering new insights into the effects of microgravity on cardiovascular function. The study highlights potential risks for astronauts during extended space missions and opens avenues for testing drugs to counteract space-induced heart deterioration.
