Life is unpredictable, and we move forward the best we can despite not knowing every detail.

It's no different in the natural world. The Earth is warming in some places and in some places it isn't, the weather is more variable today except it was always worse in the past when you talk to old people, some years there are more fish and deer than others. 

Beware people who have magic bullets when it comes to conservation; it's all based on estimates and no small amount of speculation surrounding a kernel of things we know to be true. We can only get real policies when we are flexible - sometimes that means making a decision even when unanswered questions remain. 

Might living a structured life with regularly established meal times and early bedtimes lead to a better life and perhaps even prevent the onset of mental illness?

That's what's suggested in a study led by Kai-Florian Storch, PhD, of the Douglas Mental Health University Institute and McGill University, titled "A highly tunable dopaminergic oscillator generates ultradian rhythms of behavioral arousal," and published in eLife.

Simply removing cattle may be all that is required to restore many degraded riverside areas in the American West, although this can vary and is dependent on local conditions. These are the findings of Jonathan Batchelor and William Ripple of Oregon State University in the US, lead authors of a study published in Springer's journal Environmental Management. Their team analyzed photographs to gauge how the removal of grazing cattle more than two decades ago from Hart Mountain National Antelope Refuge in eastern Oregon has helped to rehabilitate the natural environment.
