Press Release

August 24, 2016 / The origins of Cuban species / Satoshi Ohdachi / The Caribbean islands form a natural laboratory for the study of evolution due to their unique biological and geological features. There has been heated discussion since the early 20th century on how species appeared on the islands. The Cuban solenodon is a small, rare, endangered animal, belonging to the mammalian order Eulipotyphla. It is a mole-like nocturnal animal with a long snout .....
July 22, 2016 / A new key to understanding molecular evolution in space / Naoki Watanabe / Molecular hydrogen, the most abundant element in space, is created when two hydrogen atoms bond on minute floating ice particles. It has two energy states: ortho and para, depending on the direction of proton spins. Ortho-hydrogen converts to para-hydrogen on extremely low temperature ice particles, though its mechanism remained unclear. .....
Feb. 22, 2016 / Elucidation of the Formation Mechanism of Liquid Water Layers on Ice Surfaces / Gen SAZAKI / Ice surfaces are covered with thin liquid water layers, called quasi-liquid layers (QLLs), even at temperatures below melting point (0°C). This phenomenon has been called "surface melting" and is thought to be the key of a wide variety of phenomena from ice skating to the generation of thunder. However, it had been unclear how the liquid .....
Jan. 25, 2016 / Water spin isomers hide their origin / Tetsuya HAMA / Water (H2O) exists ubiquitously in space such as in the interstellar clouds in which stars are born, in proto-planetary disks, in the comets and icy satellites of the solar system, and on the Earth. Therefore, water is a molecule that is related to evolution from interstellar clouds to the solar system. By studying the properties of water that have been created in space .....
Jan. 21, 2016 / The Water Layer that Wets an Ice Surface does not Flow as Easily as Ordinary Water / Ken-ichiro MURATA / Ice surfaces are wet by a thin water layer even below 0°C. This phenomenon has been known as "surface melting" for a long time, but there are still major questions as to why the ice surface is wet. This research has focused on "quasiliquid layer (QLLs)" water layer that is formed by surface melting. We investigated .....
Sep. 07, 2015 / Large-Scale Molecular Dynamics Simulation of Water Nucleation - Success in Reproducing Laboratory Low Nucleation Rates / Kyoko TANAKA, Hidekazu TANAKA / Nucleation, in which liquid droplets form from saturated vapor, is an important research subject that spans a wide range of science and engineering fields, including meteorology (formation of cloud particles) and engineering (formation of nanoparticles). .....
Jul. 06, 2015 / Formation Route of First Chiral Amino Acid in the Universe Clarified / Yasuhiro OBA, Naoki WATANABE / Some molecules have isomers with the same composition that cannot be superimposed upon each other like our right and left hands; they are called chiral molecules. The Institute of Low Temperature Science verified the possibility that the first chiral amino acid in the universe would be formed on interstellar grains .....
Jun. 12, 2015 / Discovery of Diamonds Formed in the Earth's Crust / Akira KOUCHI / Diamonds found previously have all been formed deep in the earth at high temperatures and pressures. On the other hand, while it was understood that diamonds can be formed experimentally at the low temperatures and pressures associated with the earth's crust, none had been found in crustal rock. A joint research team from the Russian Academy of Sciences, .....
Oct. 06, 2015 / First Observation of Tunneling Diffusion of Hydrogen Atoms on the Surface of Very-Low-Temperature Water Ice / Naoki WATANABE / It is believed that, on microparticles of water ice floating in space, hydrogen atoms that have adhered in the vacuum move around on the surface of the ice and collide with other atoms and molecules to form a variety of molecules, including organic molecules. It has been .....
