Why is ice so slippery?

The answer lies in a film of water that is generated by friction, one that is far thinner than expected and much more viscous than usual water through its resemblance to the "snow cones" of crushed ice we drink during the ...

Citizen scientists re-tune Hubble's galaxy classification

Hundreds of thousands of volunteers have helped to overturn almost a century of galaxy classification, in a new study using data from the longstanding Galaxy Zoo project. The new investigation, published in the journal Monthly ...

Visualize sounds and tune instruments precisely and intuitively

A novel process for analyzing and visualizing sound has been designed by the Laboratoire Sciences et Technologies de la Musique et du Son (CNRS/IRCAM/French Ministry of Culture and Communication/UPMC). The SnailAnalyser-Tuner ...

Spirals of light may lead to better electronics

(Phys.org) —A group of researchers at the California Institute of Technology (Caltech) has created the optical equivalent of a tuning fork—a device that can help steady the electrical currents needed to power high-end ...

Are our textbooks wrong? Astronomers clash over Hubble's legacy

Edwin Hubble's contributions to astronomy earned him the honor of having his name bestowed upon arguably the most famous space telescope (the Hubble Space Telescope, HST). Contributions that are often attributed to him include ...

Fine-tuning galaxies with Herschel and Spitzer

(Phys.org)—Galaxies come in all shapes and sizes: from those with compact fuzzy bulges or central bars to galaxies with winding spiral arms. Astronomer Edwin Hubble classified these different breeds of galaxies by means ...
