But for some children, especially premature babies and those with underlying health conditions, RSV can lead to pneumonia and bronchitis – which can require hospitalization and have long-term consequences.

Networks of nanometer-scale machines offer exciting potential applications in medicine, industry, environmental protection and defense, but until now there’s been one very small problem: the limited capability of nanoscale antennas fabricated from traditional metallic components.

In the early 1990s, when Wallace H. Coulter – legendary scientist and inventor of a device to rapidly count cells – was elected as a fellow of the American Institute for Medical and Biological Engineering (AIMBE), he was unable to attend the meeting to accept the nomination. Rather than mail the award to him, Georgia Tech’s Robert Nerem, who was AIMBE’s president at the time, hopped on a plane from Atlanta and flew to Miami to present Coulter with the award in person.
