Tropical sea snake uses its head to 'breathe'

Humans use a snorkel and fish have gills. Now researchers have found a sea snake which uses a complex system of blood vessels in its head to draw in extra oxygen when it dives and swims underwater.

Nanostructured material with potential for use in catalyzers

Titanium oxide (TiO2) nanofibers can have various applications, such as in catalyzers and filters. When TiO2 is excited by ultraviolet light, it degrades organic material. Hence, TiO2 can be applied to filter wastewater for ...

A new dimension for batteries

Engineers at the University of Maryland have created a thin battery, made of a few million carefully constructed "microbatteries" in a square inch. Each microbattery is shaped like a very tall, round room, providing much ...
