Scientists have found that high carbon dioxide levels cause squid to bungle attacks on their prey.

PhD candidate Blake Spady from the ARC Centre of Excellence for Coral Reef Studies (Coral CoE) at James Cook University (JCU) led the investigation. He said that the oceans absorb more than one-quarter of all the excess carbon dioxide (CO2) released into the atmosphere by humans and this uptake of additional CO2 causes seawater to become more acidic.

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.

Sudan, the world’s last remaining male northern white rhino, has died at the Ol Pejeta Conservancy in Kenya — pushing the species even closer to extinction after decades of poaching. Just two females of the subspecies remain alive today, Sudan’s daughter and granddaughter.

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.

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.
