As wearable technologies redefine the way people exchange information, receive entertainment, and monitor health, the development of sustainable power sources that capture energy from the user's everyday activities garners increasing interest. Electric fishes, such as the electric eel and the torpedo ray, provide inspiration for such a power source with their ability to generate massive...

Biodiversity effects on grape quality depend on variety and management intensity

Steiner, Magdalena ; Grace, James B. ; Bacher, Sven

In: Journal of Applied Ecology, 2021, p. 1-13

1. Interactions between plants can be beneficial, detrimental or neutral. In agricultural systems, competition between crop and spontaneous vegetation is a major concern. We evaluated the relative support for three non-exclusive ecological hypotheses about interactions between crop and spontaneous plants based on competition, complementarity or facilitation. 2. The study was conducted in...

Seipin accumulates and traps diacylglycerols and triglycerides in its ring-like structure

Zoni, Valeria ; Khaddaj, Rasha ; Lukmantara, Ivan ; Shinoda, Wataru ; Hongyuan, Yang ; Schneiter, Roger ; Vanni, Stefano

Lipid droplets (LDs) are intracellular organelles responsible for lipid storage, and they emerge from the endoplasmic reticulum (ER) upon the accumulation of neutral lipids, mostly triglycerides (TG), between the two leaflets of the ER membrane. LD biogenesis takes place at ER sites that are marked by the protein seipin, which subsequently recruits additional proteins to catalyze LD formation....
