A protein and signaling pathway may help overcome the developmental block that keeps some leukemia cells immature. Inside the bone marrow, immature blood cells normally pass through a tightly controlled sequence of development before taking on specialized roles. In aggressive forms of leukemia, some of these precursor cells become trapped partway through that process. Instead […]
What It Takes To Make a White Blood Cell Could Unlock New Cancer Treatments
A protein and signaling pathway may help overcome the developmental block that keeps some leukemia cells immature. Inside the bone marrow, immature blood cells normally pass through a tightly controlled sequence of development before taking on specialized roles. In aggressive forms of leukemia, some of these precursor cells become trapped partway through that process. Instead […]
Scientists Turn Gut Bacteria Into Pancreatic Cancer Fighters
Engineered gut bacteria helped activate immune attacks against pancreatic tumors in animal models. Pancreatic tumors are notoriously difficult for the immune system to attack. They often create a “cold” tumor microenvironment that keeps immune cells from building an effective response, limiting the benefits of immunotherapies that have transformed treatment for several other cancers. Researchers at […]
This Smart Ring Tracks Glucose, Alcohol, and More Through Your Sweat
A new smart ring could reveal far more than how well someone slept or how fast their heart is beating. Engineers at the University of California, San Diego, have developed an experimental smart ring that continuously analyzes sweat from the finger to monitor several molecules associated with metabolism, nutrition, exercise, and alcohol consumption. The prototype […]

Did T. rex Leave These Mysterious Marks on Dinosaur Bones?
New research helps scientists determine whether marks on fossils are genuine bite marks. Deep grooves and punctures scar a small collection of dinosaur bones unearthed in Wyoming. They resemble the aftermath of a powerful predator’s bite—but fossil damage can be deceptive. Disease, erosion, insects, and exposure after death can all leave impressions that mimic tooth […]
Harvard Researchers Turn Ordinary Knitting Into Programmable Technology
Researchers developed knitted textiles that can function as switches and count steps. A piece of knitted fabric can now do more than stretch and fold. By carefully controlling its yarns and stitch patterns, researchers have made textiles that snap between stable shapes, operate electrical switches, and even track a person’s steps. Researchers at the Harvard […]

Chemists Defy Decades-Old Rules With “Free Electron” Breakthrough
Free electrons offer chemists a new way to control reactions that conventional electron transfer rules would normally prevent. Inside a reaction flask, an electron can determine which molecules combine and which remain unchanged. Chemists rely on this control to build complex compounds used in lifesaving drugs, advanced materials, and laboratory models of biological systems. One […]
