Summary: This study identifies several genes reproducibly associated with progression to infection in patients colonized by diverse Klebsiella. Patient variables, such as comorbidities, partially explain which patients will progress to Klebsiella infection, with colonization of the gut acting as a reservoir. Little is known, however, regarding Klebsiella genes that may increase risk of disease in colonized individuals.

Summary: The study introduces the first quadrupedal robot capable of morphologically adapting to different environmental conditions in outdoor, unstructured environments. Through embodied AI and an adaptation algorithm, the robot transitions between the most energy-efficient morphologies based on currently sensed terrains, showing significant performance improvements over non-adaptive approaches. This demonstration highlights the potential for a new embodied way of incorporating adaptation into future robotic designs.

Summary: Experimental evolution combined with whole-genome sequencing is a powerful method to study the adaptive architecture of selected traits. This study shows that the presence of a second stressor affects the genomic selection response, and the combination of temperature and laboratory adaptation results in widespread synergistic effects.

Summary: RNA editing by ADAR enzymes converts adenosines into inosines, altering protein-coding sequences and diversifying the proteome; recoding is abundant in neural tissues of coleoid cephalopods with over-representation of nonsynonymous edits; shared, strongly recoded sites in coleoids have been selected for proteome diversification, suggesting that an editable A is more beneficial than an uneditable A or a genomically encoded G.

Summary: Despite the significant stochastic nature of evolution, recent studies on ancient stickleback genomes suggest that our understanding of the recent evolutionary history of this species was generally accurate.

Summary: By studying the behaviours of households in Mexico, we find that remittances play an important role in the climate adaptation process. Remittances are used for adopting air-conditioning, which helps households respond to high temperatures and maintain thermal comfort at home. Different regions and income groups show variations in the use of remittances for climate adaptation. The overall increase in welfare attained by households through adopting air-conditioning can be quantified.

Summary: As global temperatures rise and incomes increase, air conditioner sales are expected to grow dramatically, with usage concentrated among high-income households. This could lead to inequality issues as adoption is heavily skewed towards wealthier households both within and between countries.

Summary: Through studying microbial experimental evolution and naval warfare, researchers have improved their understanding of innovation in financial markets. Major financial innovations often arise without explicit societal planning, and can be favored by markets in a manner similar to natural selection. By applying the concept of an adaptive landscape, researchers aim to characterize environments that enhance the speed and magnitude of innovation, particularly in portfolio management. A general taxonomy has been created to aid in the understanding and fostering of innovation in financial markets.

Summary: The study shows that Mycobacterium tuberculosis has adapted and diversified locally in the high-altitude Tibet region after sequential introductions of ancestral strains. Genetic evidence from the Tibetan population suggests unique mutations and positive selection in DNA repair enzymes, indicating adaptation to local environments in Tibet.

Summary: The Atacama Desert in Chile is a harsh environment with extreme conditions, yet it supports a diverse range of plant species including endemic plants. Research conducted in the region has identified genes associated with plant adaptation to stressful environments, including those linked to stress responses, metabolism, and energy production. This genetic information could be valuable for engineering crop resilience to climate change, especially as some Atacama plants are closely related to staple crops.

Summary: This study analyzed the evolutionary history of Nostoc strains, revealing a trend of transition from facultative symbiosis to free-living mode along with an increase in genome sizes. Intracellular symbiosis played a crucial role in Nostoc evolution, and members of Nostoc showed a preference for gene acquisition related to gene repair and recombination when adapting to free-living environments.

Summary: Cardiac adaptation to conditioning in horses was evaluated through empirical training based on trainers' experience. The study involved twelve purebred Arabian horses, aged 28.42 +/- 3.75 months, which underwent treadmill conditioning for six weeks. The results showed increased velocity and improvements in cardiac parameters, indicating the safe and efficient nature of the training program.

Summary: The study utilizes a machine-learning approach to examine the impacts of climate change on human and natural systems, revealing increasing evidence of observed global climate change impacts. Results show that robust levels of evidence for potentially attributable impacts are twice as prevalent in high-income countries compared to low-income countries.

Summary: Structural variants (SVs) have important roles in phenotypic variation, but single-nucleotide variants receive more attention. We present a simple and inexpensive method to track SV allele frequency dynamics, using triplets of primers and capillary electrophoresis.

Summary: In this study, a new microscopy technique was introduced to non-invasively assess the microsaccades and rhabdomere orientations of photoreceptors in insect compound eyes. By comparing different insect eyes, it was found that different eye types sample light information in different ways, highlighting how compound eyes convert light patterns into neural signals and how this active sampling can evolve based on insects' visual needs.

Summary: Cancer cells within tumors exhibit high phenotypic variability, allowing some cells to survive drug treatments. Reactivation of signaling is heterogeneous, with roughly 15% of cells reactivating within an hour and showing long-term resistance. Monitoring signaling dynamics at a single-cell resolution revealed the importance of rapid signaling reactivation in predicting resistance.

Summary: The study systematically identified single-gene knockouts suitable for imposing cross-feeding in Escherichia coli and used this information to assemble syntrophic communities. The interaction network between all functional groups of mutants was mapped, revealing that auxotrophs for vitamins are optimal cooperators. Assemblies composed of dozens of auxotrophs rapidly coalesced into consortia primarily made up of vitamin auxotrophs, suggesting stabilization through multiple cross-feeding interactions.

Summary: Drug metabolism by the microbiome can affect the success of anticancer treatment. Previous studies have shown that chemotherapies with antimicrobial activity can induce adaptations in bacterial drug metabolism, inadvertently influencing the host's chemoresistance. This study focuses on the degradation of gemcitabine, a nucleoside-analog chemotherapy, by Gammaproteobacteria in pancreatic tumors, which increases the tumor's resistance to the drug. The researchers found that certain mutations in Escherichia coli can increase or decrease bacterial drug breakdown, affecting the local environment and the efficacy of the drug.
