Researchers use GPS to track the timing and patterns of giant tortoise migration over multiple years. The tortoises often take the same migration routes over many years in order to find optimal food quality and temperatures. The timing of this migration is essential for keeping their energy levels high, and climate change could disrupt a tortoise's ability to migrate at the right time.

This incredible image of the hourglass-shaped Southern Crab Nebula was taken to mark the NASA/ESA Hubble Space Telescope's 29th anniversary in space. The nebula, created by a binary star system, is one of the many objects that Hubble has demystified throughout its productive life. This new image adds to our understanding of the nebula and demonstrates the telescope's continued capabilities.

A team of researchers has observed chirality for the first time in polar skyrmions, in a material with reversible electrical properties -- a combination that could lead to more powerful data storage devices that continue to hold information, even after they've been turned off.

In 2000, measles was declared to be eliminated in the United States. Today, the US and many other countries are experiencing outbreaks of measles because of declines in measles vaccine coverage. Without renewed focus on vaccination efforts, the disease may rebound in full force, according to infectious diseases experts.

The American Bumblebee - a species once more commonly seen buzzing around Southern Ontario - is critically endangered, according to a new study. The finding found the native North American species, Bombus pensylvanicus, is facing imminent extinction from Canada, considered the highest and most at-risk classification before extinction.

History can tell us a lot about the Crusades, the series of religious wars fought between 1095 and 1291, in which Christian invaders tried to claim the Near East. But the DNA of nine 13th century Crusaders buried in a pit in Lebanon shows that there's more to learn about who the Crusaders were and their interactions with the populations they encountered.

For the first time, researchers have successfully 3D printed chalcogenide glass, a unique material used to make optical components that operate at mid-infrared wavelengths. The ability to 3D print this glass could make it possible to manufacture complex glass components and optical fibers for new types of low-cost sensors, telecommunications components and biomedical devices.
