Superconductivity is still a relatively new area of science, and although much research is now focused on high-temperature cuprate perovskite superconductors, there remain significant research efforts dedicated to developing radically different types of superconductive material. Some of the potentially most useful low-temperature superconductive products of recent research have been based around doped carbon. In particular, the superconductivity of doped buckmisterfullerene (a spherical arrangement of 60 carbon atoms) was correctly predicted in 1964, 16 years before the first buckminsterfullerene-based superconductor was synthesised.

It has more recently been discovered that carbon nanotubes (carbon atoms arranged in a tubular structure) superconduct without requiring doping. These tubes have a wall one or more atoms thick, and given their tubular nature might be suitable for the construction of superconducting integrated circuits. Unfortunately, they are difficult to fabricate for this application, and require extreme refrigeration before the superconductivity is evidenced. Nevertheless, there have been recent breakthroughs in the creation of nanotube transistors, which lay the groundwork for more complicated electronics based solely on novel superconductive components. Heating nanotubes in the presence of lead has been shown to draw the metal into the tubes as if by capillary action, and given lead's known superconductivity, this may provide an alternative route to superconducting electronics.

Another breakthrough that has been made very recently is the manufacture of metallic hydrogen. While this was predicted in the 1930s, and more recently theorized to be superconductive at temperatures
possibly reaching 290K, the extreme conditions required to fabricate it have been outside the reasonable reach of technology until recently. However, the discovery of magnesium diboride superconductivity at 40K provides an experimental model of low-temperature superconductivity in boron which may be applicable to other materials such as metallic hydrogen.

The discovery of BCS superconductivity at high temperatures may lead to a significant shift in the definitions of low- and high-temperature superconductivity used today.
