Engineers report a new low-power lighting technology

Researchers from the Moscow Institute of Physics and Technology and Lebedev Physical Institute of the Russian Academy of Sciences have designed and tested a prototype cathodoluminescent lamp for general lighting. The new ...

Jets and winds from galaxy cores appear to share a common cause

Astronomers have a rough understanding of how galaxies emit jets from their cores. Galaxy cores also blow out winds of ionized gas, for which researchers lack a general explanation. SRON astronomers have now found a correlation ...

Earthworm research spurs farmers to act

A study of England's farmland has found key earthworm types are rare or absent in two out of five fields and has led to the majority of farmers affected vowing to change the way they farm.

Magnetic fields may be the key to black hole activity

Collimated jets provide astronomers with some of the most powerful evidence that a supermassive black hole lurks in the heart of most galaxies. Some of these black holes appear to be active, gobbling up material from their ...

Drought increases CO2 concentration in the air

ETH researchers have shown that during drier years, the concentration of carbon dioxide in the atmosphere rises faster because stressed ecosystems absorb less carbon. This global effect is so strong that it must be integrated ...

The remarkable jet of the quasar 4C+19.44

Quasars are galaxies with massive black holes at their cores. So much energy is being radiated from near the nucleus of a quasar that it is much brighter than the rest of the entire galaxy. Much of that radiation is at radio ...

A gamma ray burst observed in unprecedented detail

A study which is published in Nature magazine with observations from the robotic telescope MASTER-IAC at the Teide Observatory will help to clear up some unknown factors in the initial phase and the evolution of the huge ...
