Tropical forest seeds use three strategies to survive
(Smithsonian Tropical Research Institute) From tiny banana seeds to giant coconuts, it's tough for seeds to survive in tropical soils where they are under constant attack by fungi, bacteria, insects and animals. By understanding how seeds defend themselves, tropical biologists contribute to reforestation, crop management and sustainable agriculture in the tropics. (Source: EurekAlert! - Medicine and Health)

Differences in immune responses create a genetic conflict between sexes
(Lund University) A unique study from Lund University in Sweden has discovered for the first time that there is a genetic sexual conflict in the immune system in animals. In females, the variation in central genes of the immune system is too high, whereas in males, it is too low. The researchers argue that the conflict is linked to differences in the immune responses of females and males. (Source: EurekAlert! - Biology)

Heatwave and climate change having negative impact on our soil say experts
(University of Manchester) The recent heatwave and drought could be having a deeper, more negative effect on soil than we first realised say scientists. That's because organisms in soil are highly diverse and are responsible not only for producing the soil we need to grow crops, but also provide humans with many other benefits, such as cleaning water and regulating greenhouse gas emissions.

Here, there, and everywhere: The importance of ER membrane contact sites
Our textbook image of organelles has changed. Instead of revealing isolated cellular compartments, the picture now emerging shows organelles as largely interdependent structures that can communicate through membrane contact sites (MCSs). MCSs are sites where opposing organelles are tethered but do not fuse. MCSs provide a hybrid location where the tool kits of two different organelles can work together to perform vital cellular functions, such as lipid and ion transfer, signaling, and organelle division. Here, we focus on MCSs involving the endoplasmic reticulum (ER), an organelle forming an extensive network of cisternae ...
