Summary: The study found a high and recurrent amount of unsolicited emails from predatory journals, with around 42% relating to dentistry. Some emails mentioned false impact factors, and some corresponded to journals listed in the NLM catalog. Researchers should be aware of the modus operandi of predatory journals to protect their reputation and that of science.

Summary: Research has identified a new trace fossil called Pennichnus in the Miocene strata of northeast Taiwan, characterized by an L-shaped burrow with feather-like structures, indicating a connection to ambush-predatory worms from about 20 million years ago.

Summary: Between 2009 and 2012, Jeffrey Beall published four articles analyzing 18 publishers and introduced the term "predatory" in scientific publishing. He developed Beall's List in 2012, which became a valuable resource but faced criticism. Despite Beall's legacy, predatory publishing practices have not been eradicated, and there is a need for clearer guidelines for quality journals.

Summary: The study reveals the high prevalence of xerostomia among older individuals, especially at night and in women. Various factors reported earlier in life can predict the development of xerostomia. Clinicians need to be aware of this condition in the elderly and recommend appropriate measures to alleviate symptoms and minimize negative impact on oral health.

Summary: The rise of atmospheric oxygen had a significant impact on the chemistry of surficial environments and Earth's habitability. Research indicates that atmospheric oxygen levels continued to fluctuate around 2.32 billion years ago, correlating with major perturbations in ocean redox chemistry and climate. Ultimately, permanent atmospheric oxygenation was achieved around 2.22 billion years ago, about 100 million years later than previously estimated.

Summary: This study provides a comprehensive and quantitative estimate of global temperature changes over the past 540 million years, combining various paleoclimate indicators. The global temperature model includes estimates of global average temperature, tropical temperatures, deep ocean temperatures, and polar temperatures. The history of global temperature changes has been summarized into 8 major climate modes, each consisting of warming and cooling episodes influenced by geological processes.

Summary: By combining morphological, ecological, and life-history trait data with genomic-based estimates of changing effective population size, this study explores the demographic-based shifts in avian functional diversity over the past million years and under pre-anthropogenic climate warming. The results show that functional diversity remained relatively stable over this period, but significant changes occurred in some key areas of trait space due to changing species abundances. Furthermore, the study identifies the vulnerability of different regions of functional space among taxa, enhancing our understanding of losses of biosphere integrity before human disturbances and contemporary biodiversity loss.

Summary: This study investigates the vegetation history of the Amazon basin over the past 18 million years. The research suggests that the Amazonian lowlands were mainly composed of tropical rainforests, warm-temperate rainforests, and tropical seasonal forests, and their composition correlated with global climate cycles. The study also highlights the sensitivity of tropical rainforests to changes in CO2, temperature, and moisture availability.

Summary: This study reports new aphidlion-like larvae found in amber from Myanmar about 100 million years old and Baltic amber about 35 million years old. Comparing the shapes of head and stylets between different time slices, the results indicate that the diversity of head shapes remains largely unchanged over time, with a certain increase in diversity observed in the larvae of Hemerobiidae, a group of lacewings.

Summary: This study reveals the presence of two distinct mammoth lineages in eastern Siberia during the Early Pleistocene, with one lineage giving rise to the woolly mammoth and another representing an unrecognized lineage ancestral to the first mammoths to colonize North America. Additionally, the study shows that the Columbian mammoth of North America can trace its ancestry back to a hybridization event between these two lineages during the Middle Pleistocene, with roughly equal admixture proportions. Moreover, the majority of protein-coding changes associated with cold adaptation in woolly mammoths were found to be present as early as one million years ago.

Summary: Research reveals the existence of rich plant and animal communities in North Greenland two million years ago. The ancient community consisted of an open boreal forest with a variety of Arctic and boreal shrubs and herbs. Genetic analysis confirms the presence of ancestral species such as hares, mastodons, reindeer, rodents, and geese. The presence of marine organisms suggests a warmer climate than today. The findings open new possibilities for genetic research, demonstrating the use of ancient environmental DNA to track the ecology and evolution of biological communities from two million years ago.

Summary: This study reveals the genomic evolution of Thalassospira bacterial populations cultured from million-year-old subseafloor sediments, showing evolution in clonal populations by point mutation with elevated numbers of pseudogenes and numerous insertion-deletion events in a flagellar operon. Compared to type strains, subseafloor bacterial genomes have a significantly lower number of singleton genes.

Summary: Fire is a significant factor in shaping terrestrial ecosystems and its frequency fluctuated over the past two million years, showing an inverse relationship with the abundance of C4 plants. The dry climate during glacial periods increased fuel availability and fire activity. The variations in Earth orbital parameters also influenced fire occurrence.
