Published Making batteries takes a lot of lithium: Some could come from gas well wastewater
(via sciencedaily.com) Original source A new analysis suggests that if it could be extracted with complete efficiency, lithium from the wastewater of Marcellus shale gas wells could supply up to 40% of the country's demand.
Published Iconic baobabs: The origin and long-distance travels of upside down trees
(via sciencedaily.com) Original source The research cracks the code on the iconic baobab tree's origin story, revealing their surprising origins in Madagascar and incredible long-distance dispersals to Africa and Australia. The study unveils how baobabs developed unique pollination mechanisms -- some attracting hawkmoths, others lemurs, and even bats -- showcasing remarkable evolutionary adaptations. The research sheds light on how climate change has shaped the baobab's distribution and diversification over millions of years, offering valuable insights for understanding plant responses to future environmental shifts.
Published Some mice may owe their monogamy to a newly evolved type of cell
(via sciencedaily.com) Original source What makes the oldfield mouse steadfastly monogamous throughout its life while its closest rodent relatives are promiscuous? The answer may be a previously unknown hormone-generating cell. Scientists discover the cells and hormones that inspire mice to nurture their young; the same hormones are also present in humans.
Published Eco-friendly and affordable battery for low-income countries
(via sciencedaily.com) Original source A battery made from zinc and lignin that can be used over 8000 times. This has been developed with a vision to provide a cheap and sustainable battery solution for countries where access to electricity is limited.
Published Persistent strain of cholera defends itself against forces of change, scientists find
(via sciencedaily.com) Original source A longstanding mystery about the strain of Vibrio cholerae (V. cholerae) responsible for the seventh global cholera pandemic is how this lineage has managed to out-compete other pathogenic variants. The team identified a unique quirk of the immune system that protects the bacteria from a key driver of bacterial evolution.
Published Insights into protein evolution
(via sciencedaily.com) Original source A research team has unveiled a breakthrough in understanding how specific genetic sequences, known as pseudogenes, evolve.
Published Island birds more adaptable than previously thought
(via sciencedaily.com) Original source The researchers found that birds were more evolutionarily similar on smaller, more isolated islands than on larger, less remote places. The team had expected to find that forested areas had more numerous and more varied species of birds compared to farmland areas. But they were surprised to find that the opposite was true: Areas with farms and human settlements had more species of birds and greater diversity than forested areas.
Published Like dad and like mum ... all in one plant
(via sciencedaily.com) Original source Scientists have established a system to generate clonal sex cells in tomato plants and used them to design the genomes of offspring. The fertilization of a clonal egg from one parent by a clonal sperm from another parent led to plants containing the complete genetic information of both parents.
Published How do genetically identical water fleas develop into male or female?
(via sciencedaily.com) Original source Researchers have used a novel combination of short-read and long-read RNA sequencing to identify the different isoforms of genes expressed in the crustacean Daphnia magna. Males and females are genetically identical, but using this technique the team revealed genes that switch the predominant isoform in a male-female-dependent manner. This study may help further advance technologies in crustacean aquaculture.
Published Cellular activity hints that recycling is in our DNA
(via sciencedaily.com) Original source Introns are perhaps one of our genome's biggest mysteries. They are DNA sequences that interrupt the sensible protein-coding information in your genes, and need to be 'spliced out.'
Published New sex-determining mechanism in African butterfly discovered
(via sciencedaily.com) Original source In a study of a species of African butterfly, researchers have discovered a previously undescribed molecular mechanism of how the sex of an embryo is initially specified.
Published Disorder improves battery life
(via sciencedaily.com) Original source What determines the cycle life of batteries? And, more importantly, how can we extend it? An international research team has discovered that local disorder in the oxide cathode material increases the number of times Li-ion batteries can be charged and discharged.
Published Limited adaptability makes freshwater bacteria vulnerable to climate change
(via sciencedaily.com) Original source Freshwater bacteria with small genomes frequently undergo prolonged periods of adaptive stagnation. Based on genomic analyses of samples from European lakes, researchers uncovered specific evolutionary strategies that shape these bacteria's lifestyles. Understanding the evolutionary dynamics of aquatic microbial communities is key to safeguarding ecosystem services.
Published Chimps learn and improve tool-using skills even as adults, study finds
(via sciencedaily.com) Original source Chimpanzees continue to learn and hone their skills well into adulthood, a capacity that might be essential for the evolution of complex and varied tool use, according to a new study.
Published Engineers develop innovative microbiome analysis software tools
(via sciencedaily.com) Original source Engineers have developed two new graph-based computational tools for tracking genomic variation within microbiomes.
Published Genomes of 'star algae' shed light on origin of plants
(via sciencedaily.com) Original source Land plants cover the surface of our planet and often tower over us. They form complex bodies with multiple organs that consist of a broad range of cell types. Developing this morphological complexity is underpinned by intricate networks of genes, whose coordinated action shapes plant bodies through various molecular mechanisms. All of these magnificent forms burst forth from a one-off evolutionary event: when plants conquered Earth's surface, known as plant terrestrialization.
Published Cost-effective, high-capacity, and cyclable lithium-ion battery cathodes
(via sciencedaily.com) Original source Charge-recharge cycling of lithium-superrich iron oxide, a cost-effective and high-capacity cathode for new-generation lithium-ion batteries, can be greatly improved by doping with readily available mineral elements.
Published Researchers parse oddity of distantly related bats in Solomon Islands that appear identical
(via sciencedaily.com) Original source A study of body size in leaf-nosed bats of the Solomon Islands has revealed surprising genetic diversity among nearly indistinguishable species on different islands.
Published Unlocking the genetic mysteries behind plant adaptation: New insights into the evolution of a water-saving trait in the pineapple family (bromeliaceae)
(via sciencedaily.com) Original source Researchers have achieved a breakthrough in understanding how genetic drivers influence the evolution of a specific photosynthesis mechanism in Tillandsia (air plants). This sheds light on the complex actions that cause plant adaptation and ecological diversity.
Published Surprising evolutionary pattern in yeast study
(via sciencedaily.com) Original source Research study reports intriguing findings made through innovative artificial intelligence analysis about yeasts -- small fungi that are key contributors to biotechnology, food production, and human health. These findings on simple yeast organisms not only challenge widely accepted ideas about yeast evolution, but also provides access to an incredibly rich yeast analysis dataset that could have major implications for future evolutionary biology and bioinformatics research for years to come.
