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
Engineering students show off creative solutions to real-world challenges
In annual Design Day showcase, students present their designs and devices to faculty, staff, sponsors, alumni, and each other By Lisa Ercolano / Published May 3, 2021
In laboratories, design spaces, living rooms, bedrooms, and basements, students at Johns Hopkins have been working around the clock to tweak and refine their engineering creations. These projects include a new material that would make solar cells more efficient, a device that would enable earlier detection of recurrent brain tumors, and a freeze-dried bacterial powder that accelerates the process of aging cheeses.
These projects, more than 100 in all, will be presented virtually to faculty mentors, industry sponsors, fellow students, alumni, and other guests tomorrow at the Whiting School of Engineering s Design Day an annual rite of passage that showcases students ability to apply knowledge accum

New model more accurately predicts how massive glaciers melt
Statistical models of the topography of glacier beds will lead to more accurate predictions of heat flow and subsequent ice melt for decades to come By Lisa Ercolano / Published Feb 23, 2021
New research by a team that included a Johns Hopkins engineer promises to enable more accurate ice-flow predictions, helping scientists better forecast how melting glaciers will contribute to rising sea levels, which have been linked to coastal and wetland flooding and destructive erosion around the world.
Journal of Geophysical Research: Earth Surface, Harihar Rajaram and the team offer a new method of estimating how heat flows upwards from the Earth to beds of ice sheets in Greenland and Antarctica, affecting their viscosity and rates of movement.

Environmental conservation and future sustainability require innovation from chemical engineers, who can make adjustments to the microscopic structure of materials or change how large-scale industrial production is performed. One pressing challenge the industry faces is mitigating environmentally polluting forms of nitric oxide, collectively called NOx, emitted from automobile engines and industries.
A team led by Chao Wang, a professor in the Department of Chemical and Biomolecular Engineering at Johns Hopkins University s Whiting School of Engineering and an expert in high-performance catalysts, has discovered a new way to quantitatively characterize the atomic structures of active sites a location on an enz
