4 days ago · Detecting changes in the phenological responses of herbaceous species as a function of predicted climate change is important for forecasting future scenarios for the functioning of dry tropical forests, especially when predicting an increase in the frequency and intensity of extreme droughts.
17 hours ago · Mars has been exposed to ionizing radiation for several billion years, and as part of the search for life on the Red Planet, it is crucial to understand the impact of radiation on biosignature preservation. Several NASA and ESA missions are looking for evidence of ancient life in samples collected at depths shallow enough that they have been impacted by galactic cosmic rays (GCRs). In this ...
5 days ago · Our findings describe the key sequential steps involved in the evolution of P. aeruginosa from an environmental organism to a major human pathogen. These steps include saltatory evolution caused by horizontal gene transfer generating epidemic clones, varying intrinsic host affinities of these clones (linked to specific transcriptional changes enabling survival within macrophages), and multiple ...
4 days ago · Harrison Ford (born July 13, 1942) is an American actor. Regarded as a cinematic cultural icon, he has been a leading man in films of several genres and starred in many major box-office successes, particularly in the 1980s and 1990s.
5 days ago · Main conclusion The pilot-scale genome-wide association study in the US proso millet identified twenty marker–trait associations for five morpho-agronomic traits identifying genomic regions for future studies (e.g. molecular breeding and map-based cloning). Abstract Proso millet (Panicum miliaceum L.) is an ancient grain recognized for its excellent water-use efficiency and short growing ...
5 days ago · Dietary supplement use in the United States is widespread and increasing, especially among certain population groups, such as older Americans. The science surrounding dietary supplements has evolved substantially over the last few decades since their formal regulation in 1994. Much has been learned about the mechanisms of action of many dietary supplement ingredients, but the evidence on their ...
