High-risk MDS stem cells may have a dangerous weakness hidden inside their own metabolism: an “energy addiction” that researchers may be able to exploit to selectively attack the cells driving the cancer. Cancer stem cells can survive treatments that kill many of the other cells around them, allowing disease to persist or return. Now, researchers […]
Cancer Stem Cells Have an “Energy Addiction” – and Scientists Found a Way To Exploit It
High-risk MDS stem cells may have a dangerous weakness hidden inside their own metabolism: an “energy addiction” that researchers may be able to exploit to selectively attack the cells driving the cancer. Cancer stem cells can survive treatments that kill many of the other cells around them, allowing disease to persist or return. Now, researchers […]
This Simple Measurement Could Expose a Hidden Diabetes Risk (And It’s Not Your Waistline)
A new screening method uses an unexpected body measurement to estimate diabetes risk without a blood test. Researchers have developed a free online screening tool that considers the length of a person’s thigh alongside six more familiar health indicators. Called MEDWACS, the tool estimates the likelihood that an adult has prediabetes or undiagnosed type 2 […]
520-Million-Year-Old Fossil Reveals How Cephalopods Learned To Float
A 520-million-year-old fossil reveals an early stage in the evolution of cephalopod buoyancy. A tiny tube running through a shell helped early cephalopods control whether they rose or sank in the ocean. Living and extinct members of this group, including octopuses, squids, ammonites, cuttlefish, and nautiluses, have all faced the same challenge of regulating buoyancy, […]

Nearly Complete Fossil Reveals Scientists Were Wrong About This Ancient Mammal
An exceptionally preserved Cretaceous mammal challenges longstanding assumptions about early placental relatives. A nearly complete mammal skeleton recovered from Mongolia’s Gobi Desert has overturned a classification built largely from isolated teeth. Described in Nature by researchers from the American Museum of Natural History, Stony Brook University, the University of Arizona, and Arcadia University, the fossil […]
New Research Challenges Common Exercise Advice for Bone Health
Bone formation markers responded most strongly to intense activities involving explosive movement and rapid changes of direction. A sharp turn on a handball court may produce a stronger early signal of bone formation than a long walk. According to researchers at Semmelweis University, the intensity and movement patterns of exercise may matter more for bone […]

Cancer Cells Use a Sugar Shield To Hide From the Immune System
A study finds that nearby conditions and nutrients influence how cancer cells evade immune cells and how that protection might be disrupted. Cancer cells can sometimes escape immune attack by covering themselves in a dense layer of sugar-derived molecules that makes them harder for immune cells to recognize. Research from Sanford Burnham Prebys Medical Discovery […]
