High-Density Lipoproteins (HDL), also known as “good cholesterol”, remove excess cholesterol from the body’s tissues and transport it to the liver. This process is known to prevent atherosclerosis, the build-up of plaque in the walls of arteries. Atherosclerosis is associated with deadly symptoms, including heart attacks, strokes, aneurysms, and blood clots. Despite the importance of HDLs, scientists still have a limited understanding of how they are made.

Researchers from the Research Center for Materials Nanoarchitectonics (MANA), one of the centers under the National Institute for Materials Science (NIMS), Japan, report an inexpensive iron hydroxide catalyst that could support the use of sodium borohydride as a hydrogen storage material.

AIMR researchers developed a unified analytical model that explains how complex orbits—halo, and quasi-halo—emerge near Lagrange points in the restricted three-body problem. By introducing a nonlinear coupling mechanism, their approach reveals that orbit bifurcations arise without requiring frequency resonance, advancing both space trajectory design and bifurcation theory.

Researchers at the Nano Life Science Institute (WPI-NanoLSI), Kanazawa University, report in ACS Nano, how proteins in cells can be controllably activated through heating, an effect that can be used to initiate programmed cell death.
