Tech Xplore / Engineers invent wireless transceiver that rivals fiber-optic speed

A new transceiver invented by electrical engineers at the University of California, Irvine boosts radio frequencies into 140-gigahertz territory, unlocking data speeds that rival those of physical fiber-optic cables and laying ...

Medical Xpress / A mechanical view on metastasis: Tumor cell viscosity found to guide key steps in cancer spread

Millions of people worldwide are diagnosed with cancer every year. In advanced tumor diseases, cancer cells detach from the original tumor and settle in other parts of the body to form metastases. On their way, they have ...
