Scientists detect dark lightning linked to visible lightning

(Phys.org)—Researchers have identified a burst of high-energy radiation known as 'dark lightning" immediately preceding a flash of ordinary lightning. The new finding provides observational evidence that the two phenomena ...

Noise protection: Multifunctional and aesthetical

Noise abatement is growing in importance, thus, the demand for better acoustic building components raises. Scientists are developing new solutions: aesthetically good looking and flexibly applicable microperforated sound ...

Tracking down smallest biomarkers

Microvesicles are smallest cell elements which are present in all body fluids and are different, depending on whether a person is healthy or sick. This could contribute to detecting numerous diseases, such as, e.g., carcinomas, ...

PhD researcher seeks origin of cosmic rays

As cosmic ray particles penetrate our atmosphere, they collide with air molecules and produce new high-energy particles. These particles, in turn, are involved in further collisions. The whole process is known as an air shower. ...

Study explains the mystery of ball lightning

(Phys.org)—Sightings of ball lightning have been made for centuries around the world – usually the size of a grapefruit and lasting up to twenty seconds – but no explanation of how it occurs has been universally accepted ...

Controlling air flow over wings during supersonic flight

EU-funded researchers evaluated control techniques of air flow over aeroplane wings during supersonic flight. The optimal wing design developed should lead to important reductions in noise, emissions and fuel consumption.
