Researchers have created a “metallic wood” that is as strong as titanium but light enough to float in water. Right now, they can only produce a small amount of the metallic wood at a time, but if they can find a way to scale up the manufacturing process, the material could lead to highly durable smartphones and lighter cars.

DNA nanotechnology uses DNA molecules as programmable "Legos" to assemble nanostructures. But the structure of DNA is very simple and lacks the diversity of proteins, while the assembly of proteins is difficult to control with the precision of DNA. How about combining both DNA and proteins? Scientists have built a cage made of protein and DNA building blocks by using covalent bonds between them.

By using an aberration-corrected scanning transmission electron microscope, scientists were able to monitor real-time atom rearrangement during the synthesis of intermetallic nanoparticles made of platinum-tin alloy. These nanoparticles have applications in energy-efficient fuel conversion and biofuel production.

Leukemia cells have an impaired ability to get rid of iron. A nanoparticle drug called ferumoxytol delivers additional iron to these cells. The excess iron causes the leukemia cells to die. Ferumoxytol is already approved to treat anemia, so researchers know the drug is safe.

A prototype wearable device, tested in animal models, can continuously collect live cancer cells directly from a patient's blood. Developed by a team of engineers and doctors, this device could help doctors diagnose and treat cancer more effectively.
