Bad News


NASA scientists report that human-made carbon dioxide (CO2) continues to increase above levels not seen in hundreds of thousands of years: currently, about half of the carbon dioxide released from the burning of fossil fuels remains in the atmosphere and is not absorbed by vegetation and the oceans.

Let there be light!


Wow! Scientists have captured the first ever image of light as both a particle and a wave.

Quantum mechanics tells us that light can behave simultaneously as a particle or a wave. However, there has never been an experiment able to capture both natures of light at the same time; the closest we have come is seeing either wave or particle, but always at different times. Taking a radically different experimental approach, EPFL scientists have now been able to take the first ever snapshot of light behaving both as a wave and as a particle. The breakthrough work is published in Nature Communications.

A smiling lens

Sweet. NASA releases a “smiley” image of galaxy cluster (SDSS J1038+4849) and gravitational lensing (an Einstein ring) taken by the Hubble Space Telescope.

Guess who´s smiling at us …
