Ultrasound of a 4-month-old fetus

A Brief History of the Sonogram

In the mid-1950s, a Scottish obstetrician became the first to apply ultrasound technology to a pregnant human abdomen

The device includes a hemofilter made up of silicon semiconductor membranes that remove waste products from blood and a bioreactor containing renal tubule cells that regulate water volume, electrolyte balance and other metabolic functions.

Studying the stealthy strategy could help researchers develop new treatments for group A strep infections, which kill more than 500,000 people each year

The bacterium Escherichia coli, shown here, moves itself with propeller-like structures called flagella; it is one of the mobile microbes scientists have linked to cargo-carrying structures to form biohybrid microrobots.

How Tiny, Microbe-Propelled Bots Could Deliver Drugs in Our Bodies

Researchers are developing ‘hybrid biological microrobots’ to target cancer and do other work in the body

The team has applied for a patent for the material (shown here in a petri dish) and continues to test it at the micro- and nano-scale to better understand how it works.
