New valve technology promises cheaper, greener engines
Technology developed at the University of Waterloo reliably and affordably increases the efficiency of internal combustion engines by more than 10 percent.
The product of a decade of research, this patented system for opening and closing valves could significantly reduce fuel consumption in everything from ocean-going ships to compact cars.
Rain or Snow? Humidity, Location Can Make All the Difference
CU Boulder researchers have created a map of the Northern Hemisphere showing how location and humidity can affect precipitation, illustrating wide variability in how and why different areas receive snow or rain.
Monkeys faring better than plants in increasingly patchy forests of Costa Rica
Cattle ranching, agriculture and other human activities are turning Costa Rican forests into isolated patchy fragments, causing more problems for native plant populations than for monkey species sharing the same habitat.
Extreme Cold Winter Weather Conditions, Such As ‘Beast from the East’, Can Be Linked To Solar Cycle
Periods of extreme cold winter weather and perilous snowfall, similar to those that gripped the UK in a deep freeze with the arrival of the ‘Beast from the East’, could be linked to the solar cycle, pioneering new research has shown.
Study: Climate change soon to be main cause of heat waves in West, Great Lakes
A new analysis of heat wave patterns appearing today in Nature Climate Change concludes that climate change driven by the buildup of human-caused greenhouse gases will overtake natural variability as the main cause of heat waves in the western United States by the late 2020s and by the mid-2030s in the Great Lakes region.
