A new scientific study has raised red flags over the presence of uranium in the breastmilk of lactating mothers across six districts of Bihar, indicating potential health risks for infants who rely exclusively on breastmilk during their early months of life. The research, published in Scientific Reports, is the first assessment of uranium contamination in breastmilk in the Gangetic plains of Bihar — a region already known for toxic exposure to heavy metals like arsenic, lead, and mercury. The researchers analysed breastmilk samples from 40 lactating mothers between 17 and 35 years of age, selected from Bhojpur, Samastipur, Begusarai, Khagaria, Katihar, and Nalanda. Every participant provided informed consent, and detailed interviews were conducted to understand breastfeeding practices, child growth, and residential history. The study was conducted by teams from Mahavir Cancer Sansthan & Research Centre (Patna), Lovely Professional University, NIPER-Hajipur, and other collaborating institutions. One of the most striking findings is stated clearly in the paper: “The present study reports 100% lactating mothers having their breastmilk highly contaminated with uranium.” #news #science #scrolllink

Scientists have discovered a gene called CYP26B1 that may enable the regeneration of amputated body parts in humans. This gene is active in axolotls and acts like a “cellular mapmaker,” instructing stem cells to precisely and orderly form new tissues at the site of injury. The axolotl’s extraordinary ability to regenerate limbs, as well as parts of its heart and brain, is largely due to the activity of this gene. CYP26B1 functions by regulating levels of retinoic acid (RA), a molecule that plays a key role in determining cell fate. When tissue is damaged, the gene establishes highly specific signaling pathways that guide stem cells to differentiate into skin, muscle, or bone. Without this gene, complete regeneration of limbs would be nearly impossible. Studies on human stem cells have shown promising results. When researchers placed human stem cells under laboratory conditions mimicking those of injured axolotl tissue, and manipulated retinoic acid levels while activating or deactivating CYP26B1, they observed regeneration-like behavior: cells differentiated into specific tissues instead of growing randomly. This provides strong evidence that a similar genetic pathway could potentially be activated in humans. This discovery offers hope for a future where humans might also regenerate lost body parts. If researchers succeed in safely and precisely activating the CYP26B1 pathway in humans, it could usher in a new era of regenerative medicine—one in which restoring amputated limbs and rebuilding vital tissues moves beyond miracle and into reality. #science #biology #medicine #scrolllink
