Attentional failures after sleep deprivation are locked to joint neurovascular, pupil and cerebrospinal fluid flow dynamics

Attentional failures after sleep deprivation are locked to joint neurovascular, pupil and cerebrospinal fluid flow dynamics - Nature Neuroscience
Yang et al. show that moments of failed attention we experience after sleep deprivation reflect brief ‘sleep-like’ episodes in the brain, corresponding to a brain- and body-wide event with altered bra...

Very cool. Obesity v age impact on metabolic flux:

Re: lactate (obvi):

Aging: serum lactate concentration increases (even though whole-body lactate flux stays ~ same).

Obesity (ob/ob): serum lactate concentration increases, and lactate flux also rises strongly (~50–85% vs. lean).

Effect of sweeteners and sweetness enhancers on weight management and gut microbiota composition in individuals with overweight or obesity: the SWEET study - Nature Metabolism
The SWEET project is a multicenter, randomized, controlled trial that shows that long-term consumption of sweeteners and sweetness enhancers improves body weight control and elicits beneficial gut microbiota changes in adults with overweight or obesity.

To be clear, there are no data that provide a link between short-term use of Tylenol during pregnancy and autism. In fact, one of the best prospective studies w/ sibling controls, if anything, pointed to a protective effect for use less than 7 days
