Study: Gaps Widen in the Intercity Bus and Rail System, Forcing More to Drive

Wed, 23 Aug 2017 10:05:15 EST

(image) For nearly a decade, the rollout of new express bus and train service made it easier for Americans to put down their car keys and hop on a bus or train for intercity travel. But declining gas prices and fewer public transportation options are forcing travelers back behind the wheel, according to DePaul University researchers. A new study from the Chaddick Institute for Metropolitan Development shows that the country's push for a balanced transportation system has hit the brakes.(image)



Peas That Like It Hot

Wed, 23 Aug 2017 09:00:00 EST

(image) As the global climate changes and temperatures continue to rise, heat stress is becoming a major limiting factor for pea cultivation. A new study indicates that pea plants with some specific traits - such as longer flowering time and higher pod numbers - may be more resistant to heat stress. The researchers also gained new insights into the genetics of heat tolerance in pea.(image)
