According to a study in rodents led by Prof. Charles Bourque of McGill University, the brain’s biological clock stimulates thirst in the hours before sleep. This image shows thirst neurons (blue) in mouse SCN. Image credit: C. Gizowski et al / McGill University. Biologists knew that rodents show a surge in water intake during the last two hours before sleep. The new study revealed that this behavior is not motivated by any physiological reason,...

Mosaic of the Valles Marineris hemisphere of Mars projected into point perspective, a view similar to that which one would see from a spacecraft. The distance is 1,550 miles (2,500 km) from the surface of the planet. The mosaic is composed of 102 Viking Orbiter images of Mars. The center of the scene shows the entire Valles Marineris canyon system, over 1,240 miles (2,000 km) long and up to 5 miles (8 km) deep, extending form Noctis Labyrinthus, the arcuate system of graben to the west, to the chaotic terrain to the east. Many huge ancient river channels begin from the chaotic terrain from north-central canyons and run north. The three Tharsis volcanoes (dark red spots), each about 15.5 miles (25 km) high, are visible to the west. South of Valles Marineris is very ancient terrain covered by many impact craters.

On Monday, September 19, 2016, OSIRIS-REx’s OCAMS MapCam camera recorded a star field in Taurus, north of the constellation Orion as part of the spacecraft’s post-launch instrument check. MapCam’s first color image is a composite of three of its four color filters, roughly corresponding to blue, green, and red wavelengths. The three images are processed to remove noise, co-registered, and enhanced to emphasize dimmer stars. Image credit: NASA / Goddard / University of Arizona.

This colorful view of Mercury was produced by using images from the color base map imaging campaign during MESSENGER’s primary mission. These colors are not what Mercury would look like to the human eye, but rather the colors enhance the chemical, mineralogical, and physical differences between the rocks that make up the planet’s surface.

Dr. Stocker and co-authors describe Triopticus primus, a bizarre Late Triassic animal, whose skull structure is converged on by distantly related dome-headed pachycephalosaurs. The unique body plans observed in Triopticus primus and other archosaurs at the ‘dawn of the age of dinosaurs’ re-evolved in dinosaurs and crocodylians after the end-Triassic mass extinction.
