As humans continue to pump carbon dioxide (CO2) into the atmosphere, some of the CO2 gets absorbed into the sea, which raises its acidity--a process called ocean acidification. Scientists are seeking to learn whether or not organisms can adapt to this threat--whether or not species can evolve along with the ocean, adapting over time to the increasing acidity. Hannes Baumann, an assist...
Venus, as seen in radar with the GBT News.science360.gov.org
A projection of radar data of Venus collected in 2012. Striking surface features such as mountains and ridges are easily seen. The black diagonal band at the center represents areas too close to the Doppler "equator" to obtain well-resolved image data. The surface of Venus is shrouded beneath thick clouds--made mostly of carbon dioxide--and therefore difficult to see from Earth using ...

The John Day Fossil Beds National Monument spreads across northern Oregon in three sections. The Painted Hills Unit, near Mitchell features hills that appear to be taken directly from an Impressionist canvas. The colors include many shades of yellow, grey, black and red. These colors originated with mineral and organic material as well as r...

Qomolangma or Mount Everest, the highest point on our planet, is the focal point of the Himalayan Range. It lies in eastern Nepal, close to the border of Nepal and Tibet, China. I visited this region shortly before the deadly earthquake on April 25, 2015. I was here not to climb Qomolangma but rather ...

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...

Wandering through the E.H. Lohbrunner Alpine Garden in UBC Botanical Garden, I couldn't help but notice this beautiful, flowering Asphodelus aestivus. The bees were enjoying these flowers as much as I was (or maybe more), but I didn't manage to get a good photo of the bees flitting in and out of the nectar-rich flowers. Thankfully, Gideon Pisanty is a more patient photographer than I am. He c...
Solanum pyracanthos BotanicalGarden.ubc.ca
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...
