In vitro antibacterial activity of crude extracts from Tithonia diversifolia (asteraceae) and Solanum torvum (solanaceae) against selected shigella species

Crude extracts from Tithonia diversifolia and Solanum torvum exhibit significant antibacterial activity against selected Shigella species. Hexane extract from S. torvum and dichloromethane extract from T. diversifolia inhibit bacterial growth with minimum inhibitory concentration values of 500 and 1,000 µg/mL.

Women more likely to choose wine from female winemakers

Research from Washington State University found that women are willing to pay higher prices for wines made by female winemakers, particularly those featuring feminine gender cues. The study suggests that promoting women's ownership in wineries can increase sales among the largest group of U.S. wine consumers, who happen to be women.

Local water supply crucial to success of hydrogen initiative in Europe

A new study from Chalmers University finds that local water supply is critical to the success of Europe's hydrogen initiative, with some regions facing severe water shortages if production is not planned carefully. The research suggests that areas like Sweden's Sörmland and Roslagen could be hard-pressed even without hydrogen production.

Do muscles remember being weak?

New research reveals that skeletal muscle retains a 'molecular memory' of repeated disuse, which differs between young and old muscles. Younger muscles show resilience, while older muscles become increasingly susceptible to atrophy. The study provides insights into how muscle responds to inactivity and its potential for recovery.
