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.

Hubble celebrates its 29th birthday with unrivaled view of the Southern Crab Nebula

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.

General anesthesia hijacks sleep circuitry to knock you out

Researchers have found that general anesthesia induces unconsciousness by hijacking the neural circuitry that makes us fall sleep. They traced this neural circuitry back to a cluster of cells at the base of the brain responsible for churning out hormones to regulate bodily functions, mood, and sleep. The finding could lead to better drugs capable of putting people to sleep with fewer side effects.

Giant tortoises migrate unpredictably in the face of climate change

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.

Bacterial therapy in a dish

Biomedical engineers have developed a system that can study 10s to 100s of programmed bacteria within mini-tissues in a dish, condensing study time from months to days. The speed and high throughput of their technology allows for stable growth of bacteria within tumor spheroids and can also be used for other bacteria species and cell types. The team says this study is the first to rapidly screen and characterize bacteria therapies in vitro.

Giving robots a better feel for object manipulation

A new learning system improves robots' abilities to mold materials into target shapes and make predictions about interacting with solid objects and liquids. The system, known as a learning-based particle simulator, could give industrial robots a more refined touch -- and it may have fun applications in personal robotics, such as modelling clay shapes or rolling sticky rice for sushi.

Why lightning often strikes twice

Scientists have used the LOFAR radio telescope to study the development of lightning flashes in unprecedented detail. Their work reveals that the negative charges inside a thundercloud are not discharged all in a single flash, but are in part stored alongside the leader channel at Interruptions, inside structures which the researchers have called needles. This may cause a repeated discharge to the ground.

Scientists have long known that Earth and Mercury have metallic cores. Like Earth, Mercury's outer core is composed of liquid metal, but there have only been hints that Mercury's innermost core is solid. Now, in a new study, scientists report evidence that Mercury's inner core is indeed solid and that it is very nearly the same size as Earth's solid inner core.
