To transport an ion against its concentration gradient requires energy, which in the biological membrane is supplied by metabolic or chemical reactions. By the Curie–Prigogine principle of ...

Teeth are composites of mineral and protein, with a bulk of bony dentin that is highly porous. This structure allows teeth to ...

Bacterial cells growing in biofilms are physiologically distinct from free-swimming planktonic cells. For example, differences have been shown in motility, polysaccharide production, antibiotic ...

Advanced imaging revealed a sharp zinc increase toward the tooth pulp, tracking higher dentine porosity. The results could ...

Modern cycling demands more than strong legs and high aerobic capacity. Today’s rider builds performance through structured training, sharp tactical thinking, and steady concentration.

Human MAP1LC3B (LC3B) binds proteins involved in autophagy and other cellular processes using a degenerate four-residue short linear motif known as the LC3-interacting region (LIR). Biochemical and ...

The evidence is solid but not definitive, as the conclusions rely on the absence of changes in spatial breadth and would benefit from clearer statistical justification and a more cautious ...

Are we on the brink of a revolution in imaging?Researchers at KAIST have developed a metamaterial-based image sensor architecture that overcomes one of the major barriers to real-world deployment ...

Permafrost regions contain a globally significant mercury (Hg) reservoir. An estimated 1,656 ± 962 Gg total Hg in Northern Hemisphere permafrost-region soils, with 793 ± 461 Gg frozen in ...

Background/aims Posterior capsule opacification (PCO) is the most frequent long-term complication after cataract surgery, caused by proliferation of residual lens epithelial cells (LECs). Metformin, a ...

Nootropic beverages include coffee, green tea, and fermented drinks like kombucha and kefir. They may support focus or brain health, but firm evidence is limited. Coffee’s caffeine may improve ...
