Coastal cities worldwide would face a reduced threat from sea level rise if society reduced greenhouse gas emissions, with especially significant benefits for New York and other U.S. East Coast cities, new research indicates.

The study, by scientists at the National Center for Atmospheric Research (NCAR), used a powerful computer model to tease out the ways that winds and currents in a warming world push ocean water around, lifting it in some regions and lowering it in others. The scientists examined how these variations in sea level rise would change under two conditions: if emissions continue on their current trajectory, or if they are sharply reduced.

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.

MIT researchers have developed a system that can produce images of objects shrouded by fog so thick that human vision can’t penetrate it. It can also gauge the objects’ distance.

An inability to handle misty driving conditions has been one of the chief obstacles to the development of autonomous vehicular navigation systems that use visible light, which are preferable to radar-based systems for their high resolution and ability to read road signs and track lane markers. So, the MIT system could be a crucial step toward self-driving cars.

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.

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.
