Tokyo, Japan - Researchers from Tokyo Metropolitan University and Hosei University have discovered a new species of large, tropical centipede of genus
Scolopendra in Okinawa and Taiwan. It is only the third amphibious centipede identified in the world, and is the largest in the region, 20 cm long and nearly 2 cm thick. It is also the first new centipede to be identified in Japan in 143 years, testament to the incredible biodiversity of the Ryukyu Archipelago.
Scolopendra is a genus of large, tropical centipede, one of the original genera named by the father of modern taxonomy himself, Carl Linnaeus. They are strong predators in any soil ecosystems they inhabit, with around 100 different species found in tropical regions around the world. Of these, only five have been identified in Japan and Taiwan.

(a)-(c) show how the Seebeck coefficient varies for 1D, 2D and 3D materials, while (d)-(f) show the thermoelectric conductivity for the same systems. No major changes in the shape of the curves are seen for (a)-(c); drastic changes are seen for (d)-(e) beyond a threshold range marked in yellow, making thermoelectric conductivity a much more sensitive, unambiguous measure for dimensionality.

As the global economy adapts to the transition away from carbon-based sources of energy, there is an increased focus on the use of renewable energy to provide a zero-emission source of electrical power. An integral part of the solution is batteries and energy storage systems. One Japanese company that is leading the field in this respect is The Furukawa Battery Company (Furukawa Battery).
Furukawa Battery traces its origins back to 1914, when Furukawa Electric established its battery factory in Amagasaki City, Hyogo Prefecture, and started production of lead-acid batteries. In 1950 Furukawa Electric spun off its battery business, and Furukawa Battery as a separate company was formed. Since then, the company has continued to evolve & expand, and now employs over 2,400 people.

Tokyo, Japan - Researchers from Tokyo Metropolitan University have shown that a quantity known as thermoelectric conductivity is an effective measure for the dimensionality of newly developed thermoelectric nanomaterials. Studying films of semiconducting single-walled carbon nanotubes and atomically thin sheets of molybdenum sulfide and graphene, they found clear distinctions in how this number varies with conductivity, in agreement with theoretical predictions in 1D and 2D materials. Such a metric promises better design strategies for thermoelectric materials.
