Tsetse fly. Credit: Dr. Hester Weaving The fertility of both female and male tsetse flies is affected by a single burst of hot weather, researchers at the University of Bristol and Stellenbosch University in South Africa have found. The effects of a single heat wave were even felt in the offspring of heat-exposed parents, with … Read more

Credit: American Society for Horticultural Science Ginger is one of the world’s leading spice crops, and is used for both its medicinal and flavor qualities. It grows well in tropical regions and its rhizomes mature in eight to nine months from planting. Rising consumer demands for organically grown crops in the U.S. provide the opportunity … Read more
(A) The ECF profile of S. meliloti is compared to the heterologous ECF switches that were shown to be active in the Rm1021 wild type and/or the ECF/anti-σ-free strain. Phylogenetic groups are given on top. If 2 groups are listed, the first one refers to the initial classification [13] and the second one to the … Read more
AI-assisted annotation helps users in marine biodiversity observations from real-time video feeds. Credit: Wave Labs Numerous measurement stations around the world provide us with data about air quality, allowing us to enhance it. Although we are increasingly collecting data from marine areas, access to such data is considerably more challenging. Signals are poorly transmitted through … Read more
Credit: CC0 Public Domain Global species diversity is in decline almost everywhere, largely due to human-driven development and resource use. Typically, conservation efforts have targeted the most endangered species, which can lead to some tough choices on how to balance limited resources. But there’s an argument to be made that it is more effective and … Read more
