EDITORIAL
Kaja Plucińska, Steven W Barger
This editorial highlights an article by McKee and colleagues in the current issue of Journal of Neurochemistry, in which the authors report epigenetic changes linked to one-carbon metabolism in prefrontal cortex (PFC) of murine offspring from dams fed high-fat diet to mimic maternal obesity. The group found that high-fat diet feeding in utero increases weight gain in offspring and dynamically alters DNA methylation in the PFC of male but not female brains. These epigenetic marks were associated with a shift in brain one-carbon metabolism (folate and methionine) intermediates and were normalized by early-life methyl-donor supplementation in a sex-specific manner...

PURPOSE: Exercise economy is one of the main physiological factors determining performance in endurance sports. Running economy (RE) can be improved with running-specific training, while the improvement of cycling economy (CE) with cycling-specific training is controversial. We investigated whether exercise economy reflects sport-specific skills/adaptations or is determined by overall physiological factors. METHODS: We compared RE and CE in 10 runners, 9 cyclists and 9 triathletes for running at 12 km/h and cycling at 200 W...

We use integrated circuit-based frequency-to-voltage conversion of a frequency comb beat signal as the means for laser frequency stabilization that is suitable for narrow-line laser cooling. The method is compared to an atomic beam lock where the laser frequency instability for the new scheme shows an improvement of 2 orders of magnitude at sub-1 s and grants a lock-capture range that is approximately 30 times greater. We employ the locking method on a 1111.6 nm laser that is frequency doubled and used in a dual-wavelength magneto-optical trap for Yb171 atoms, producing atomic cloud temperatures of ∼20  μK...

In Boulanger et al. (2018), we assessed the role of ungulates' presence on short-term understory plant dynamics, using a nationwide network composed of paired exclosure-control plots. We demonstrated that ungulates are key drivers of understory vegetation in managed forests since they alter the richness and abundance of the shrub layer, increase the richness of the herb layer and favour open habitat plant species. Our results show that local scale mechanisms, here involving indirect facilitation, lead to global dynamics in forest-ungulate systems...
