Part education tool, part neuroscience party trick, the Glassbrain app was first used on stage in 2012 on Mickey Hart, former drummer for the Grateful Dead, to show his brain reacting to music. A cap detects the different types of waves and signals pinging across the user's brain. The app then displays them in real time on a 3-D image built from brain scans taken earlier. Each color r...

Summary Author: Thomas McGuire   In spite of its currently moderate climate, Ireland displays impressive features of past glaciation from periods of geologic history known as Ice Ages. One example is the drumlin field of Clew/Newport Bay, on the island's North Atlantic coast. In fact, the name drumlin is derived from the Irish word, droiroimnín (littlest ridge).

Astronomers using NASA's Hubble Space Telescope have discovered an immense cloud of hydrogen dubbed "The Behemoth" bleeding off a planet orbiting a nearby star. The enormous, comet-like feature is about 50 times the size of the parent star. The hydrogen is evaporating from a warm, Neptune-sized planet, due to extreme radiation from the star. A phenomenon this l...

Quasars are the light fantastic. They are the brightest beacons in the universe, blazing across space with the intrinsic brightness of one trillion suns. Yet the objects are not vast galaxies, but they appear as pinpoint sources in the biggest telescopes of today hence the term "quasar" for quasi-stellar object. Discovered in the 1960s, it took more than two d...

Solanum pyracanthos

Don McClane (aka Don McClane@Flickr) took this beautiful photo at Botanica Gardens in Wichita, Kansas. Solanum pyracanthos is native to Madagascar and is a member of the genus that includes tomatoes, potatoes and eggplants. I wouldn't try to eat the small fruits without a good indication of their edibility, however, as many members of the Solanum are poisonous (at least when raw).

Solanum is o...

Carex utriculata

Today's photo features a stand of Carex utriculata, photographed by Matt Lavin (aka Matt Lavin@Flickr). This strikes me as an uncommonly beautiful image of the common beaked sedge.

I have had a fondness for sedges ever since I took one of my first ecology classes, when my fiery Scottish professor taught me, in a thick, R-rolling brogue, that "Rrrrushes are rrrround, and sedges have edges!" I h...
