Should We Invest in Martian Brine Research to Reduce Mars Exploration Costs?

S ince publication of the first evidence of liquid water on present-day Mars (Martı́n-Torres et al., 2015) according to Curiosity data, scientists have wondered how best to further investigate the presence of brines. Initial evidence was acquired at Gale Crater, near the equator of the planet, a location where this presence of liquid water was highly unexpected. This evidence was later corrobora...

Catalyst Research Promises to Reduce Scr Costs

If adopted by EPA, proposed new regulations on stack emissions will force many utilities with coalfired boilers to reduce their NOx emissions to levels which are substantially lower then can be achieved with current low NOx burner technology. To meet these requirements, some utilities are anticipating the need to use selective catalytic reduction (SCR) for NOx control. New SCR catalysts under d...

Should we invest in environmental interventions to encourage physical activity in England? An economic appraisal.

BACKGROUND The Department of Health in England asked the National Institute for Health and Clinical Excellence (NICE) to develop guidance on environmental interventions that promote physical activity. The economic appraisals summarized in this study informed the development of that guidance. In view of the difficulties inherent in applying conventional health economic evaluation techniques to p...

Should We Use PPAR Agonists to Reduce Cardiovascular Risk?

Trials of peroxisome proliferator-activated receptor (PPAR) agonists have shown mixed results for cardiovascular prevention. Fibrates are PPAR-alpha agonists that act primarily to improve dyslipidemia. Based on low- and high-density lipoprotein cholesterol (LDL and HDL) effects, gemfibrozil may be of greater cardiovascular benefit than expected, fenofibrate performed about as expected, and beza...
