• Investigating and Influencing How Buildings Affect Health: Interdisciplinary Endeavours

Noise exposure has been the focus of research attention for nearly 40 years, since the classic work by Glass and Singer (1972). Several studies have documented adverse effects of chronic noise exposure on children, including disrupted reading acquisition (Bronzaft & McCarthy, 1975; Evans & Maxwell, 1997), memory impairment (Hygge, Evans, & Bullinger, 2002), and physiological stress responses (Evans, Hygge, & Bullinger, 1995). Fortunately, these effects appear to be reversible: The introduction of noise attenuation strategies resolved reading problems in elementary school children (Bronzaft, 1981), and the end of chronic noise exposure (because of the closing of a nearby airport) reversed the adverse effects on memory (Hygge et al., 2002). There is mounting evidence that ...

• Wacky, Weird Earn Ig Nobels

This year's winners honoured -- or maybe dishonoured -- at a raucous ceremony yesterday at Harvard's inappropriately opulent Sanders Theater include a doctor who put his finger on a cure for hiccups; two men who think there is something to the old adage that feet smell like cheese; and researchers who discovered that dung beetles won't tuck in to just any old pile of... well, dung. Dr. Francis Fesmire said he wasn't sure whether he was honoured or embarrassed when he learned he'd won an Ig Nobel for his paper called -- ahem -- "Termination of Intractable Hiccups with Digital Rectal Massage. I'm a serious guy, and something I wrote in 1987 is coming back to haunt me," said Fesmire, an emergency physician and director of the emergency heart centre at Erlanger Medical Center in Chattanoo...

• This Jeep's a Gas -- Literally

Bet we would have liked it in summer, too. With a new "Canadian pricing" base sticker of $41,945, the Grand Cherokee SRT8 will power past many European-built performance sport-utilities that cost much more. Top speed is estimated at 240 km/h plus. Zero-to-96 km/h is under five seconds. Impressive for anything on wheels, astounding for a 2,200-kg truck. Great off-roader, too. Nah, we joke. The SRT8 is meant to go nowhere a paving crew hasn't gone before. Yes, it has all-wheel-drive, but power is distributed through a car-based, open-differential system best-suited to fast times on smooth roads, not the boonie-conquering Quadra-Drive or Quadra-Trac found in the $33,045-to-start regular Grand Cherokee. Our tester, an '07, came with the usual hefty helping of extras, from sunroof to navigat...
