A groundbreaking new study by researchers at Israel’s Weizmann Institute of Science may soon revolutionize how we diagnose blood cancers and understand aging. Published today in Nature Medicine, the research led by Profs. Liran Shlush and Amos Tanay introduces a simple blood test that could replace painful bone marrow biopsies for detecting early signs of myelodysplastic syndrome (MDS) — a precursor to leukemia. The study arrives under extraordinary circumstances, just days after the researchers’ labs sustained serious damage in an Iranian missile strike. Yet, despite the upheaval, their findings are poised to create lasting impact. A New Window into Aging and Disease The scientists have been tracking how blood-forming stem cells change with age. Their earlier research revealed that about one-third of individuals over 40 begin to accumulate mutations in these cells — mutations linked not only to leukemia but also to heart disease and diabetes. In the latest study, Dr. Nili Furer, Nimrod Rappoport, and Oren Milman, together with collaborators in Israel and the U.S., showed that even rare stem cells that temporarily leave the bone marrow and enter the bloodstream carry vital diagnostic information. By applying cutting-edge single-cell genetic sequencing to these cells, researchers could identify signs of MDS — a condition where stem cells don’t mature correctly, potentially leading to severe anemia or progression to acute myeloid leukemia (AML). A Less Invasive, More Insightful Test Until now, MDS diagnosis depended on invasive bone marrow sampling. The new blood test promises to change that. It not only flags MDS early but may also evaluate the risk of progression to leukemia, making it a vital tool for prevention and early intervention. The researchers also found that these circulating stem cells act as an internal “aging clock.” Intriguingly, the cells undergo changes earlier in men than in women — possibly shedding light on why blood cancers are more prevalent among males. Broad Potential, Global Trials The innovation is now undergoing clinical trials at medical centers worldwide. Scientists believe that this technology could eventually be used to detect a wide range of blood-related diseases beyond leukemia. Bridging Medicine and Science Beyond his lab work, Prof. Liran Shlush plays a central role in shaping the future of medicine. He is a senior physician at Assuta Medical Center and Maccabi Healthcare Services, and he now heads the newly founded Miriam and Aaron Gutwirth Medical School at the Weizmann Institute. The school, opening in October, aims to blend scientific research and clinical training into a unified curriculum — preparing a new generation of physician-scientists who can navigate both the lab bench and the hospital ward with equal skill. This landmark study not only underscores the Weizmann Institute’s global leadership in biomedical research but also offers hope that one day, a routine blood test could help detect — and possibly prevent — life-threatening diseases long before symptoms appear.

A recent study has identified 22 previously unknown viruses in the kidney tissues of 142 bats collected from Yunnan province, China, between 2017 and 2021, according to reports by Newsweek and The Sun. Among them, two viruses show genetic similarities to the deadly Hendra and Nipah henipaviruses, both known for causing severe brain inflammation and respiratory illness in humans. 🔬 Key Discoveries from the Study: ⚠️ Why This Matters: The findings come in the shadow of the COVID-19 pandemic, which also originated from China and raised global awareness about zoonotic viruses — those that spill over from animals to humans. While no direct threat has yet been reported from these newly found viruses, researchers have warned about their zoonotic potential. Molecular virologist Prof. Vinod Balasubramaniam said the discovery is “concerning” due to the location of the viruses in kidneys, potentially allowing urine to contaminate fruits or water supplies, especially in regions with close human-animal proximity. 🧬 Context & Implications: 📌 FAQs 1. Is the China bat virus dangerous? While the newly found viruses haven’t infected humans yet, scientists have called them “critical zoonotic threats” that require urgent surveillance. 2. Could there be another pandemic from bats? There is no current evidence of an imminent pandemic. However, the risk of spillover events continues to exist due to close human-wildlife interactions. 3. What virus is spreading in China? Researchers recently discovered 20+ new viruses in bats, but none have been reported as spreading among humans. Monitoring is ongoing. 🧪 Bottom Line: This research serves as a timely reminder that early detection and ecological surveillance are critical in preventing the next potential pandemic. Scientists are urging global health agencies to step up monitoring of zoonotic reservoirs, especially in regions with dense wildlife-human interfaces.
