What Colors are the Dress? Three Perspectives on Why the Image is seen Differently

May 15, 2015 3:57 pm | by Cell Press | News | Comments

When you look at this photograph, what colors are the dress? Some see blue and black stripes, others see white and gold stripes. This striking variation took the Internet by storm in February; now Current Biology is publishing three short papers on why the image is seen differently by different observers, and what this tells us about the complicated workings of color perception.

Aircraft positions are picked up by the Proba-V mini-satellite, using an experimental ADS-B receiver. These signals are regularly broadcast from aircraft, giving flight information such as speed, position and altitude. Proba-V has picked up upwards of 25 million positions from more than 15,000 separate aircraft. The team has identified more than 22,000 unique call signs, identifying more than 15,000 aircraft.

Scientists have spied a vast reservoir of hot, partly molten rock beneath the supervolcano at Yellowstone National Park. It's big enough to fill the Grand Canyon 11 times over. The gigantic magma chamber is four times bigger and much deeper than the previously known chamber above it. The upper chamber was responsible for three ancient volcanic eruptions that coated much of North America in ash.

How is lightning initiated in thunderclouds? This is difficult to answer — how do you measure electric fields inside large, dangerously charged clouds? It was discovered, more or less by coincidence, that cosmic rays provide suitable probes to measure electric fields within thunderclouds. The measurements, including the strength of the electric field at a certain height in the cloud, were performed with the LOFAR radio telescope.
