When females mate promiscuously, sperm from rival males compete within the female
reproductive tract to fertilize ova. Sperm competition is a powerful selective force that has shaped …

Sperm competition favors increases in relative testes mass and production efficiency, and
changes in sperm phenotype that result in faster swimming speeds. However, little is known …

The purpose of this study is to investigate how to recycle FFP2 face masks used during

Swellable PEG amine/dextran aldehyde composite materials are emerging as a controlled,
biocompatible tissue adhesive. We explain how preservation of natural tissue amines …

Exploration of marine-derived actinomycetes as a source of antitumor compounds has led
to the isolation of a new member of the tartrolon series, tartrolon D (4). This new compound …

The polyketide pederin family are cytotoxic compounds isolated from insects, lichen, and
