海洋葉劍水蚤(桡足类动物)快速变色和隐形之谜被解开,光学意义非凡 Revealed: Stunning Sea Sapphire’s Magic Trick

The tiny, beautiful sea sapphire dazzles observers with its ability to turn various jewel-like colors – and become invisible. The Weizmann Institute’s Prof. Lia Addadi, Prof. Steve Weiner, and others reveal how <em>Sapphirinidae</em> pulls off its magic trick, which could have applications such as adaptive reflective coatings and optical mirrors.

New Method for Nanoparticle Self-Assembly May Lead to Novel Applications, Like Rewritable Paper

Unlike current methods that coat nanoparticles with light-sensitive molecules, a new technique from the Weizmann Institute instead suspends the particles in a light-sensitive medium, then self-assemble. Possible applications include rewritable paper, water decontamination, and a way to precisely deliver medicines.

肠道微生物种群对健康至关重要, 通过各种微生物的不同的生长速度可建立哪些微生物与不同疾病的关系 Assessing Bacteria Growth Rate Gives Novel Insight into Health and Microbiome

Investigating how the microbiome impacts human health, the labs of Dr. Eran Elinav and Prof. Eran Segal at the Weizmann Institute of Science took a fresh approach: measuring the growth rate of the bacteria. The findings led Dr. Elinav to say, “microbial growth rate reveals things about our health that cannot be seen with any other analysis method.”
