Surface plasmon polaritons (SPPs) are highly localized surface waves on the interface between metal and dielectric in the optical frequency band. SSPs do not naturally exist in the microwave and terahertz frequencies, so spoof surface plasmon polaritons (SSPPs) are necessary for operations in those lower frequency bands.
Like optical SPPs, microwave SSPPs exhibit highly localized electromagnetic fields, subwavelength resolution, and extraordinary field confinement. Therefore, SSPP transmission lines (TLs) have been proposed as novel types of microwaveguides that offer new solutions for miniaturization, signal integrity, and low crosstalk in compact circuits for use in wireless communications and wearable electronics.

A Johns Hopkins University-led team has created an inexpensive portable device and cellphone app to diagnose gonorrhea in less than 15 minutes and determine if a particular strain will respond to frontline antibiotics.
The invention improves on traditional testing in hospital laboratories and clinics, which typically takes up to a week to deliver results time during which patients can unknowingly spread their infections. The team s results appear today in
Science Translational Medicine. Our portable, inexpensive testing platform has the potential to change the game when it comes to diagnosing and enabling rapid treatment of sexually transmitted infections, said team leader Tza-Huei Wang, a professor of mechanical engineering and core researcher at the Institute for NanoBioTechnology at Johns Hopkins Whiting School of Engineering. It ensures that patients are diagnosed on the spot, and treatment can begin immediately, improving clinical outcomes. This will be especi

When the Big One hits, the first thing Washington residents notice may not be the ground shaking but their phone issuing a warning. The U.S. Geological Survey, the University of Washington-based Pacific Northwest Seismic Network, and the Washington Emergency Management District on Tuesday, May 4, will activate the system that sends earthquake early warnings throughout Washington state. This completes the tri-state rollout of ShakeAlert, an automated system that gives people living in Washington, Oregon and California advance warning of incoming earthquakes.

NEW YORK, May 12, 2021 A new Computer Aided Design (CAD) platform for whole genome design is being launched by two pioneers in the world of biotech:
Genome Project-write (GP-write) and
Twist Bioscience
(NASDAQ: TWST). The technology is expected to open up new frontiers in genome research with real world applications to advance development of therapeutics and solutions for environmental health.
The CAD technology will be an important development along the path to more facile writing of genomes, by eliminating a host of barriers that hinder genome design. Current platforms can be limited to small-scale changes in bacterial systems. The GP-write CAD will allow scientists to scale to other species with larger genomes. It will also automate workflows to enable collaborative efforts critical for scale-up from designing plasmids (kilobases) to whole chromosomes (megabases) across entire genomes (gigabases).

A team of engineers recommends expanding fast-charging stations for electric vehicles as campuses and businesses start planning for a post-pandemic world.
The recommendation is based on a study of charging patterns for electric vehicles on the University of California San Diego campus from early January to late May of 2020, after the university moved most of its operations online. Researchers say the findings can be applied to a broader range of settings.
