Researchers found elderly patients (over 64), women (35%), black patients (6%), and diabetic patients (25%) are disproportionately affected by late hospital arrivals.
Contact lens solutions may not kill off harmful eye bugs
Researchers found that some contact lens solutions may not effectively kill Acanthamoeba cysts, which can lead to serious eye infections. The two-step hydrogen peroxide solution was the most effective against both trophozoites and cysts.
Nanowire-based electronics and optics comes one step closer
Researchers have successfully fabricated nanowires that combine diverse materials, paving the way for ultra-small-scale electronics and optoelectronic devices. The breakthrough could lead to significant advancements in fields such as energy production and manufacturing, and may even help address concerns about Moore's Law.
