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.
Researchers studying how the brain makes decisions have, for the first time, recorded the moment-by-moment fluctuations in brain signals that occur when a monkey making free choices has a change of mind. The findings result from experiments led by electrical engineering Professor Krishna Shenoy, whose Stanford lab focuses on movement control and neural prostheses — such as artificial arms — controlled by the user's brain.
Scientists require high-resolution imaging of plant cells to study everything from fungal infections to reproduction in maize. These images are captured with scanning electron microscopy (SEM), where an electron microscope focuses beams of electrons to increase magnification of objects. SEM is a common technique for all fields of science.

Peering into the heart of the Milky Way galaxy, NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) has spotted a mysterious glow of high-energy X-rays that, according to scientists, could be the "howls" of dead stars as they feed on stellar companions.
A 7.8-magnitude earthquake struck Nepal on April 25, 2015, claiming over 5000 lives and affecting millions of people. Satellite images are being used to support emergency aid organizations, while geo-scientists are using satellite measurements to analyze the effects of the earthquake on the land.
Most people are naturally adept at reading facial expressions — from smiling and frowning to brow-furrowing and eye-rolling — to tell what others are feeling. Now, scientists have developed ultra-sensitive, wearable sensors that can do the same thing. Their technology, reported in the journal ACS Nano, could help robot developers make their machines more human.
In order to sing or speak, around one hundred different muscles in our chest, neck, jaw, tongue and lips must work together to produce sound. Researchers investigate how all these mechanisms effortlessly work together — and how they change over time. With a new magnetic resonance imaging (MRI) technique, the vocal neuromuscular movements of singing and speaking can now be captured at 100 frames per second.
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.
Carnegie Science announces the launch of the Carnegie Airborne Observatory-3 (CAO-3), the most scientifically advanced aircraft-based mapping and data analytics system in civil aviation today. This third-generation aircraft has been completely overhauled from previous models, boasting a multitude of cutting-edge improvements to its onboard laboratory.
On April 25, 1990, astronauts aboard the Space Shuttle Discovery deployed the Hubble Space Telescope into Earth orbit and launched a new era of astronomical discovery. In its quarter-century in orbit, the world’s first space telescope has transformed our understanding of our solar system and beyond. Now, 25 years later, organizations around the world are joining in a celebration of this remarkable observatory.
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.
The Signal Processing Component Library for .NET is a comprehensive library of .NET components designed for rapid development of signal processing applications in the sound and vibration marketplace. Each component contains properties and methods that can be used to perform single-channel (spectrum, auto-spectrum, power spectral density) and two-channel (frequency response functions, cross spectrum functions) FFT operations.
GPU4EO Challenge 2015 is an international initiative which involves students, researchers and professionals in a challenge aimed at improving the performance of remotely sensed data processing using the capacity of GPUs.
