Paleontology student Hillary McLean is seen here, on November 25, 2014, piecing together the tusk of an ancient mastodon. The fossil was part of an extensive discovery unearthed from Snowmass, Colorado. The discovery of ancient bones is providing an intriguing glimpse into what happened some 120,000 years ago when the Earth was as warm as it is today. (AP)

After spending 5 ½ months in orbit aboard the International Space Station, crew member Alexander Gerst of Germany is seen here being helped out a Soyuz TMA-13M space capsule after safely landing in a remote area in northern Kazakhstan November 10, 2014. Gerst returned to Earth with his fellow crewmembers Maxim Suraev of Russian and Reid Wiseman from the United States. (Reuters)

Here’s a microscopic view of the transfer of Bluefin tuna reproductive cells into a mackerel fry surrogate. If successful, this procedure will produce tuna when it matures. Researchers at Tokyo University of Marine Science and Technology are fine-tuning a technology to use mackerel surrogates to spawn the Bluefin to help relieve pressure on wild fish stocks while preserving vital genetic diversity.

This is a high-fidelity supercomputer simulation of magnetic field loops on the sun. NASA researchers use these simulations to learn how these magnetic fields emerge, heat the sun’s outer atmosphere and produce sunspots and flares. NASA featured this and a number of other computer simulations at SC14, the international supercomputing conference held from November 16-21, 2014 in New Orleans. (NASA/Ames)
