Developing a sensor to detect disease-transmitting mosquitoes

Mosquitoes inhabit various world regions, with more than 3,000 species already identified. Some of these are transmission vectors of several diseases, such as malaria, yellow fever, or dengue. According to the World Health ...

New research reveals invisible meteors

In a new thesis from the Swedish Institute of Space Physics and UmeƄ University, unique methods for the analysis of radar data and simulations of meteoroids in the solar system are presented. The methods have been applied ...

Colliding magnetic fields reveal unknown planets

Ph.D. candidate astronomer Rob Kavanagh has developed mathematical models to better understand the interactions between exoplanets and stellar winds and to define features of exoplanets.

Research advances artificial enzyme engineering

While corrosion resistance, durability and low cost make plastic a very efficient resource, one of its major drawbacks is the harm it poses to the environment. According to a report from Greenpeace U.S., 51 million tons of ...

NASA sounding rockets launch multiple science payloads

Newly proven technology developed at NASA's Wallops Flight Facility near Chincoteague, Virginia, turns a single sounding rocket into a hive deploying a swarm of up to 16 instruments. The technology offers unprecedented accuracy ...

Radio

Radio is the transmission of signals by modulation of electromagnetic waves with frequencies below those of visible light. Electromagnetic radiation travels by means of oscillating electromagnetic fields that pass through the air and the vacuum of space. Information is carried by systematically changing (modulating) some property of the radiated waves, such as amplitude, frequency, or phase. When radio waves pass an electrical conductor, the oscillating fields induce an alternating current in the conductor. This can be detected and transformed into sound or other signals that carry information.
