A team led by the University of Tsukuba has discovered a key component of the molecular motors that drive motility in cells, such as sperm cells or unicellular algae that swim using flagella. A novel protein, named DYBLUP, is part of the linkage between the motor complexes and cellular microtubules that produce movement in flagella, and is also centrally involved in cell responses to blue light.

Researchers have introduced a new method for taking high-resolution images of fast-moving and rotating objects in space, such as satellites or debris in low Earth orbit. They created an imaging process that first utilizes a novel algorithm to estimate the speed and angle at which an object in space is rotating, then applies those estimates to develop a high-resolution picture of the target.
Scientists have long used information from sediments at the bottom of the ocean to reconstruct the conditions in oceans of the past.
