Silencing lipid catabolism determines longevity in response to fasting
Abstract Oscillations between lipid anabolism and catabolism are essential for maintaining cellular health during metabolic fluctuations. Fasting, a conserved determinant of aging, improves disease outcomes and extends lifespan, yet the relative contributions of lipid catabolism versus its attenuation to fasting-induced longevity remain unresolved. The metabolic flexibility of C. elegans under variable nutrient availability provides a powerful system to address this question.

Photo-thermally controlled Cu nanoparticles density in SWCNT/Cu nanocomposites-based flexible EMI shielding electrodes
Photo-thermally controlled Cu nanoparticles density in SWCNT/Cu nanocomposites-based flexible EMI shielding electrodes† In this study, single-walled carbon nanotube (SWCNT)/Cu nanocomposites were systematically synthesized from oxidized SWCNTs and Cu formate via photothermal heating. The incorporation of Cu nanoparticles (Cu NPs) on the surface of SWCNTs, especially for a weight ratio of 1 : 20, enhanced the electrical conductivity of the SWCNTs, resulting in a resistivity of 80 μΩ cm.
Control of Cellular Differentiation Trajectories for Cancer Reversion (Adv. Sci. 3/2025)
Graphical Abstract Cancer Reversion In article number 2402132, Kwang-Hyun Cho and co-workers present a generic computational framework, single cell Boolean network inference and control (BENEIN). Applying BENEIN to human large intestinal single cell transcriptome data, we identify MYB, HDAC2, and FOXA2 as master regulators whose inhibition can induce enterocyte differentiation.
Yin Yang 1 and guanine quadruplexes protect dopaminergic neurons from cellular stress via transmissive dormancy - Nature Communications
Abstract Neurons deploy diverse adaptive strategies to ensure survival and neurotransmission amid cellular stress. When these adaptive pathways are overwhelmed, functional impairment or neurodegeneration follows. Here we show that stressed neurons actively induce a state of transmissive dormancy as a protective measure. Extending observations of neurotrauma in C.
Rapid and Highly Selective Fe(IV) Generation by Fe(II)-Peroxyacid Advanced Oxidation Processes: Mechanistic Investigation via Kinetics and Density Functional Theory
Introduction Click to copy section linkSection link copied! Fe(II) activation of dioxygen and peroxides plays an essential role in natural environments and living cells. (1−5) The Fenton-like reactions between Fe(II) and peroxides generate highly oxidative species, including high-valent iron and/or hydroxyl radicals, which can initiate advanced oxidation processes (AOPs).
Higher Hippocampal Diffusivity Values in Welders Are Associated with Greater R2* in the Red Nucleus and Lower Psychomotor Performance
INTRODUCTION: Chronic excessive welding exposure may be related to higher metal accumulation and structural differences in different subcortical structures. We examined how welding affected brain structures and their associations with metal exposure and neurobehavioral consequences. METHODS: Study includes 42 welders and 31 controls without a welding history.
Advanced parametrization for the production of high-energy solid-state lithium pouch cells containing polymer electrolytes - Nature Communications
Abstract Lithium batteries with solid-state electrolytes are an appealing alternative to state-of-the-art non-aqueous lithium-ion batteries with liquid electrolytes because of safety and energy aspects. However, engineering development at the cell level for lithium batteries with solid-state electrolytes is limited.

To quantitatively probe iron intermediate species [Fe(V)/Fe(IV)] in Fe(VI) oxidation, this study systematically investigated the reaction kinetics of Fe(VI) oxidation of 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic)acid (ABTS) at different ratios of [ABTS]0/[Fe(VI)]0 (i.e., >1.0, =1.0, and <1.0) in pH 7.0 phosphate (10 mM)-buffered solution.
Anaerobic Dehalogenation by Reduced Aqueous Biochars
Dehalogenation is one of the most important reactions for eliminating trace organic pollutants in natural and engineering systems. This study investigated the dehalogenation of a model organohalogen compound, triclosan (TCS), by aqueous biochars (a-BCs) (<450 nm). We found that TCS can be anaerobically degraded by reduced a-BCs with a pseudo first-order degradation rate constant of 0.0011–0.011 h–1.

Graphene quantum dots as anti-inflammatory therapy for colitis
Abstract While graphene and its derivatives have been suggested as a potential nanomedicine in several biomimetic models, their specific roles in immunological disorders still remain elusive. Graphene quantum dots (GQDs) may be suitable for treating intestinal bowel diseases (IBDs) because of their low toxicity in vivo and ease of clearance. Here, GQDs are intraperitoneally injected to dextran sulfate sodium (DSS)–induced chronic and acute colitis model, and its efficacy has been confirmed.
Cobalt/Peracetic Acid: Advanced Oxidation of Aromatic Organic Compounds by Acetylperoxyl Radicals
Peracetic acid (PAA) is increasingly used as an alternative disinfectant and its advanced oxidation processes (AOPs) could be useful for pollutant degradation. Co(II) or Co(III) can activate PAA to produce acetyloxyl (CH3C(O)O•) and acetylperoxyl (CH3C(O)OO•) radicals with little •OH radical formation, and Co(II)/Co(III) is cycled.
Advanced Oxidation Process with Peracetic Acid and Fe(II) for Contaminant Degradation
Fe(II) is an excellent promoter for advanced oxidation processes (AOPs) because of its environmental ubiquity and low toxicity. This study is among the first to characterize the reaction of peracetic acid (PAA) with Fe(II) ion and apply the Fe(II)/PAA AOP for degradation of micropollutants. PAA reacts with Fe(II) (k = 1.10 × 105–1.56 × 104 M–1 s–1 at pH 3.0–8.1) much more rapidly than H2O2 and outperforms the coexistent H2O2 for reaction with Fe(II).
