1. Pregnant women who work nights may have a greater risk of miscarriage
   Working two or more night shifts in a week may increase a pregnant woman's risk of miscarriage the following week by around a third, shows a prospective study.

   
2. The largest delta plain in Earth's history
   The largest delta plain in Earth's history formed along the northern coast of the supercontinent Pangea in the late Triassic. Its size out-scales modern counterparts by an order of magnitude, and approximates 1 percent of the total land area of the modern world. And although contenders are found in the rock record, no ancient counterpart exceeds the extent of the Triassic delta plain mapped in the subsurface Barents Sea either.

   
3. New virtual reality tool allows you to see the world through the eyes of a tiny primate
   Imagine that you live in the rainforests of Southeast Asia, you're a pint-sized primate with enormous eyes and you look a little like Gizmo from the movie, 'Gremlins.' You're a tarsier -- a nocturnal animal whose giant eyes provide you with exceptional visual sensitivity, enabling a predatory advantage. A new virtual reality (VR) software, Tarsier Goggles, simulates a tarsier's vision and illustrates the adaptive advantage of this animal's oversized eyes.

   
4. Replacing sitting time with physical activity associated with lower risk of death
   For those who get the least amount of physical activity, replacing a half hour of sitting time with physical activity was associated with up to a nearly 50 percent reduction in mortality, according to a new study.

   
5. Restoring this enzyme's function protects against heart disease in lupus and beyond
   Patients with lupus are at increased risk of heart disease. Exposing endothelial cells -- known to protect against heart disease, in part by producing nitric oxide -- to the serum of patients with lupus decreased nitric oxide production. Administering L-sepiapterin restored that production.
