Full Text:

A close-up image of brain coral in the Dry Tortugas, Fla. Brain coral gets its name from the colony’s meandering, brain-like pattern of brown walls, separated by gray or green depressions known as "valleys." Each head of coral is formed by a colony of genetically identical polyps, which secrete a hard skeleton of calcium carbonate. Brain corals extend their tentacles to catch food at ...

A model of a skull created for use in a medical study using cutting-edge, 3-D printing technology at the National Center for Rapid Technologies (RapidTech). The model was created on a 3-D printing machine equipped with a stereolithography apparatus (SLA), one of several methods used to create 3-D-printed objects. Instead of extruding ink or some other liquid onto a surface, such as wi...

Photographer: Geir T. B. Øye Summary Authors: Geir T. B. Øye; Jim Foster   This impressive display of electric-blue-white noctilucent clouds was observed over Ørsta, Norway, in the early hours of August 4, 2015. These polar mesospheric clouds take shape 30 to 55 mi (50 to 87 km) above the Earth’s surface as water vapor condenses around small particles that are thought to be of meteoric origin....

One night this summer, a group of friends and I enjoyed a paddle in the Mosquito Lagoon of the Merritt Island National Wildlife Refuge in Florida. Our paddling disturbed dinoflagellates in the lagoon prompting them to emit this beautiful blue light -- bioluminescence. In some cases bioluminescence is a means to attract prey ...

Quasars are the light fantastic. These brilliant cores of active galaxies blaze with the radiance of a hundred billion stars compressed into a region of space not much larger than our solar system. Supermassive black holes, with millions or billions of times the mass of our sun, are the only imaginable powerhouse behind these tsunamis of raw energy.

A team of astronomers, including half a dozen from the Space Telescope Science Institute (STScI) in Baltimore, Maryland, have used the Gemini Observatory's new Gemini Planet Imager to find the most solar system-like planet ever directly imaged around another star. The planet, known as 51 Eridani b, is about two times the mass of Jupiter and orbits its host star...

Coffea arabica

I think about plants a lot. I notice them as I walk outside and of course I spent half of my week during the summer photographing and writing about plants for Botany Photo of the Day. Despite this, there is only one species that I think about each and every day: Coffea arabica. I have long appreciated the beauty of roasted coffee beans, but did not realize that the fruit are so attractive. Than...

Monstera deliciosa Monstera deliciosa

Some botanical names make me wonder about the botanists who dictated them, and this is one of those examples. Yes, Monstera deliciosa has monstrous leaves. And yes, its fruit, tasting of a mix of pineapple and banana, are indeed delicious. I like to think, however, that Frederik Michael Liebmann, the botanist who named this species, had a bit of a sense of humour. More likely Liebmann, a Danis...
