Elektra One solar-powered aircraftMeet Elektra One Solar, a second-generation solar-powered aircraft that is close to being mass produced, according to its manufacturer. Developed by SolarWorld in partnership with PC-Aero, the one-seater prototype can carry a payload of roughly 220 pounds and cruises at about 87 mph.
The aircraft is powered by a lithium-ion battery and also is equipped with solar cells on its wing surface, which PC-Aero says provide about half the energy required for flying.

Researchers at the University of Illinois at Urbana-Champaign have
developed a low-cost sensor called MoboSens that lets users test water quality. MoboSens connects to the audio jack of a smartphone, allowing an app running on the phone to collect the sensing data and send it to the cloud for storage and analysis.

Fighting Dengue Fever

Australian scientists have created a vaccine that they believe could eradicate dengue fever — a fatal disease spread by mosquitoes — which more than 2.5 billion people are at risk of contracting, according to the World Health Organization.

Scientists discovered their ammunition in the Wolbachia bacteria found in fruit flies. In a two-year trial conducted in Australia, the Wolbachia bacteria was transferred to mosquitoes and successfully suppressed transmission of the disease.
