4Biology is a focused search engine built for biology students, researchers, educators, and lab managers. We combine multiple indexes, curated sources, and AI tools to surface publications, protocols, datasets, suppliers, and learning resources that matter to life scientists. Use the site to save time, find specialized resources, and get context-specific search results not optimized for general web traffic. Part of the 4SEARCH network of topic specific search engines.
EurekAlert! The left agar plate shows a Pandoraea bacterial strain (P. norimbergensis deltapdnM) that only produces pandorachelin B. The strain on the right agar plate (P. norimbergensis WT) only produces pandorachelin A. Elena Herzog and Keishi Ishida, Leibniz Institute for Natural Product Research and…
Close examination of the preserved material documented sex-associated differences that are relevant to future identification. The mature male had nine large backward-pointing tubercles on the back, compared with three in the female. Its mouth floor carried seven transverse rows of…

Wheat flour owes its distinctive dough properties largely to gluten proteins, whose composition influences whether flour is suitable for bread, steamed…
Ward’s method was used to construct a cluster analysis for assessing similarity among the four communities. The researchers also calculated the percentage dissimilarity in diversity between pairs of sites. Together, these methods assessed not only which organisms were detected, but…
A European study found that solvent-free volatile-compound profiles separated 14 selected mint family taxa and revealed three distinct chemotypes within each of four genera. A study of 14 selected mint family taxa found that profiles of volatile organic compounds could distinguish plants…
A multi-locus study described ten new fungi, including nine white-rot species in Ceriporia and Meripilus, and estimated that both genera diversified during the late Cretaceous. Subject of Research: Phylogeny, divergence times, and taxonomy of fungi in Irpicaceae and Meripilaceae Article…
Maximum-likelihood and Bayesian analyses produced similar trees and placed the sampled Vietnamese populations with the Guangxi type series of R. napoensis. The encompassing R. napoensis clade was highly supported and contained two sub-clades. One contained the type-series sequences and the Bac Giang…
Three slightly different attractant traps—transparent traps containing wine or beer and a yellow trap containing wine—captured 99.4% of the Periscelididae collected. A total of 305 males of the new species were trapped. The material was initially preserved in ethanol, after…
A team led by evolutionary biologist Volker Nehring is investigating the extent to which ants learn from past experiences. Ants are aggressive towards their neighbours The scientists conducted an experiment in two phases. In the first phase, ants gained various…
The species has elevated lateral-line pores above the pectoral fin, three preopercular pores, 42–43 precaudal vertebrae and 134–137 vertebrae in total. Head length is 16.4–17.6% of total length, trunk length is 21.0–23.1%, and preanal length is 38.3–39.7%. Fresh animals have a brown upper body, a…
