Summary: For long timescale regimes, traditional statistical mechanics needs to consider the non-Gaussian tails of distributions, which make the concept of temperature invalid. This paper discusses the observational challenges of non-Gaussian behavior, the direct linkage between non-Gaussian behavior and time-coarse graining, and the production of even more non-Gaussian behavior by truncating the tails in the probability density function (PDF).

Summary: This study designed and tested simplified glass feed compositions to investigate the effects of sulfur and potassium on rhenium retention. The results supported the previously proposed mechanisms regarding the effects of sulfate and volatile components on the retention of rhenium.

Summary: Decoding cellular changes in Alzheimer's disease through large cohorts with defined clinical stages is critical for understanding the diverse trajectories of AD progression. In this issue of Cell, five studies have utilized single-nuclei RNA sequencing (snRNA-seq) and single-nuclei ATAC sequencing (snATAC-seq) at an unprecedented scale, shedding light on cell-type-specific mechanisms underlying the progression of AD pathogenesis.

Summary: This study presents fundamental research on the extraction of technetium from acid nuclear waste using a supramolecule called dicyclohexano-18-crown-6 (DCH18C6) in a isodecyl alcohol-n-DD diluent system. The authors found that the highest extraction and recovery of technetium (D-Tc approximately 2.03 and ~99% recovery) were achieved when using an organic phase containing 0.4 M DCH18C6 in 50% isodecyl alcohol + n-dodecane to extract technetium from a 4.0 M HNO3 solution. Different extraction mechanisms were identified based on the acidity of the feed solution. The study also revealed the importance of hydration energy in the extraction process.

Summary: This article is the second in a series about sabbaticals in academia, providing perspectives before, during, and after the sabbatical. It discusses the realities of being on sabbatical in a distant location from a cultural and research perspective, covering aspects such as education, travel, cuisine, networking, and conferences. It also delves into unexpected lessons learned about preparation, healthcare, vehicles, time zone challenges, and managing expectations.

Summary: This study presents a general strategy for the design of poly(ionic liquids)@COF composites for sequestration of (TcO4-)-Tc-99 from alkaline nuclear waste. The optimized composite exhibits excellent alkaline stability, fast exchange kinetics, high uptake capacity, superior selectivity, and good reusability, making it a promising sorbent for (TcO4-)-Tc-99 removal.

Summary: Krishnan et al. present a single-cell transcriptomic atlas of chronic myeloid leukemia (CML) at diagnosis in the latest issue of Blood. They identify cellular features at diagnosis that can predict the response to tyrosine kinase inhibitor (TKI) therapy by comparing different groups with varying treatment outcomes.

Summary: The lead-technetium pyrochlore structure has been refined using synchrotron X-ray and neutron powder diffraction data, with electron diffraction confirming the results. The oxygen deficient oxide has a stoichiometry of Pb2Tc2O7-d. X-ray absorption spectroscopy at the Tc K-edge showed that the valence of Tc is greater than 4.0, while Raman spectroscopy confirmed the presence of disorder, indicating that this pyrochlore is the first example of a valence V technetium oxide.

Summary: The article examines Ross's recent interventionist view of causation, considering electronic configurations of atoms as causes of chemical behavior. It argues that both nuclear charge and electronic structure play a role in chemical behavior, emphasizing the importance of dynamic interactions between nuclear charges and electrons. It concludes that electronic configurations can only be considered causal in a weak sense, similar to causal arguments in folk physics.

Summary: Hasok Chang has advocated pluralism, pragmatism, and an associated view of natural kinds in the philosophy of science. He argues that everyday terms persist in the scientific view, with examples like phlogiston being transformed into useful concepts. Chang also points out that certain scientific terms, such as acidity, have experienced a form of rupture in modern definitions like the Lewis definition of acids.

Summary: This article responds to Jensen's critique of the use of triads of elements. It explores Mendeleev's use of triads and the modern use of atomic number triads. The article argues in support of Janet's left-step periodic table, using atomic number triads and the phenomenon of first member anomaly. The article also mentions the dual sense of the term element in the philosophy of chemistry.

Summary: The article discusses two equally valid ways of understanding the nature of chemical bonding, the structural and energetic views. While Weisberg argues that the energetic view is more correct, the author believes both views are equally valid, with differences in their applications.
