				"abstractNote": "Metabolites in the kynurenine pathway, generated by tryptophan degradation, are thought to play an important role in neurodegenerative disorders, including Alzheimer's and Huntington's diseases. In these disorders, glutamate receptor-mediated excitotoxicity and free radical formation have been correlated with decreased levels of the neuroprotective metabolite kynurenic acid. Here, we describe the synthesis and characterization of JM6, a small-molecule prodrug inhibitor of kynurenine 3-monooxygenase (KMO). Chronic oral administration of JM6 inhibits KMO in the blood, increasing kynurenic acid levels and reducing extracellular glutamate in the brain. In a transgenic mouse model of Alzheimer's disease, JM6 prevents spatial memory deficits, anxiety-related behavior, and synaptic loss. JM6 also extends life span, prevents synaptic loss, and decreases microglial activation in a mouse model of Huntington's disease. These findings support a critical link between tryptophan metabolism in the blood and neurodegeneration, and they provide a foundation for treatment of neurodegenerative diseases."

In this article, we examine why this may be the case by reviewing evidence from both laboratory experiments on humans and ecologically relevant studies on non-human animals. Generally, punishment appears to be most probable if players differ in strength or strategic options. Although these conditions are common in nature, punishment (unlike other forms of aggression) involves immediate payoff reductions to both punisher and target, with net benefits to punishers contingent on cheats behaving more cooperatively in future interactions. In many cases, aggression yielding immediate benefits may suffice to deter cheats and might explain the relative scarcity of punishment in nature."

				"abstractNote": "SR proteins constitute a family of pre-mRNA splicing factors now thought to play several roles in mRNA metabolism in metazoan cells. Here we provide evidence that a prototypical SR protein, ASF/SF2, is unexpectedly required for maintenance of genomic stability. We first show that in vivo depletion of ASF/SF2 results in a hypermutation phenotype likely due to DNA rearrangements, reflected in the rapid appearance of DNA double-strand breaks and high-molecular-weight DNA fragments. Analysis of DNA from ASF/SF2-depleted cells revealed that the nontemplate strand of a transcribed gene was single stranded due to formation of an RNA:DNA hybrid, R loop structure. Stable overexpression of RNase H suppressed the DNA-fragmentation and hypermutation phenotypes. Indicative of a direct role, ASF/SF2 prevented R loop formation in a reconstituted in vitro transcription reaction. Our results support a model by which recruitment of ASF/SF2 to nascent transcripts by RNA polymerase II prevents formation of mutagenic R loop structures."
