Hokkaido University is a major national research university in Sapporo, Japan, with programs spanning natural sciences, agriculture, and engineering.
A study of 136 museum skulls from Hokkaido found winter snouts about 7 percent taller and 6 percent wider even as the braincase shrank. The authors call it a reverse Dehnel's phenomenon.

The Sapporo startup's cap table now includes a rubber and plastic moulder, and its roadmap now includes large rocket motors. The in-orbit firing test is still ahead of it.

Squid fossils from the Western Interior Seaway push the group's known Cretaceous range to the other side of the globe, about a million years before the asteroid impact that has long been credited with spreading them.

Kawahara and Osugi built 3D models that stood upright or bowed and showed them to raters in six countries. The increase in rated attractiveness appeared among the Japanese participants and barely moved elsewhere.

A Hokkaido University team drilled aluminum poles into northwestern Greenland's ice every summer from 2012 to 2025, and the record they built traces about half of the growing loss low on the glacier to the ice itself slowing down.

Shortening structures turn up more often on smooth ground than on rough. Correcting for that detection bias raises Mercury's radial contraction from 8.3 to 11.6 kilometres, and the authors say even that is probably low.

MoOCl2 is metallic along one crystal axis and dielectric along the perpendicular one, and an Okayama-led team used that split to measure a dielectric quality factor of 45.3 in nanodisks on gold, about 5.7 times the plasmonic mode's.

An Institute of Science Tokyo team chained an enzyme to molecular motors to build DNA networks on a surface. Pull the ATP and nothing assembles, but the energy bill is still unwritten.
