Urchin-loving otters can help fight global warming
A thriving sea otter population that keeps sea urchins in check will in turn allow kelp forests to prosper; the spreading kelp can absorb as much as twelve times the amount of CO2 from the atmosphere than if it were subject to ravenous sea urchins

New search-and-rescue tool: remotely controlled cockroaches
Researchers have developed a technique that uses an electronic interface to remotely control, or steer, cockroaches; remotely controlling cockroaches would allow first responders to create a mobile web of smart sensors that uses cockroaches to collect and transmit information, such as finding survivors in a building that has been destroyed by an earthquake

Protecting buildings from earthquakes by hiding them
Engineers have come up with an inventive and exciting idea for protecting buildings from earthquakes: hide them (the buildings, that is); the engineers say that placing specialized rubber under the building would diverts certain temblor shock waves, leaving the building virtually untouched by them

Scientists question earthquake prediction methods
From 2008 to 2011, three earthquakes have significantly damaged different parts of the world. Those quakes were significantly underestimated by scientists and seismologists

Crack-resistant components for bridges, roof structures, cars
Bridges, roof structures, cars, and more should become increasingly lighter, with the same stability, and thus save energy and materials; the new high-strength steel is superbly suited for the needed lightweight design because it can also withstand extremely heavy stresses; yet these materials also have a disadvantage: with increasing strength, their susceptibility to cold cracking rises when welded; cracks are difficult to predict — until now

Airbus unveils its 2050 vision for “Smarter Skies”
Global aircraft manufacturer Airbus the other day released the latest installment of the Future by Airbus, its vision for sustainable aviation in 2050 and beyond; the vision looks beyond aircraft design to how the aircraft is operated both on the ground and in the air in order to meet the expected growth in air travel in a sustainable way

Destroyed coastal habitats produce significant amounts of greenhouse gas
Destruction of coastal habitats may release as much as one billion tons of carbon into the atmosphere each year, ten times higher than previously reported; a new analysis provides the most comprehensive estimate of global carbon emissions from the loss of these coastal habitats to date: 0.15 to 1.2 billion tons; it suggests there is a high value associated with keeping these coastal-marine ecosystems intact as the release of their stored carbon costs roughly $6-$42 billion annually

Students create low-cost biosensor to detect contaminated water
Diarrheal disease is the second-leading cause of death in children under five years old — killing as many as 1.5 million children worldwide every year; these startling statistics from the World Health Organization (2009) point to the reason why a group of undergraduate students from Arizona State University is working to develop a low-cost biosensor — a simple device that would detect contaminated drinking water

Law-enforcement agencies eager for Web-surveillance tools
Private technology firms are pitching software capable of analyzing large swaths of the Internet to local law enforcement looking for ways to stop the next mass shooting or domestic terrorist event before it happens; police departments hope the software will help them detect online information from terrorists, traffickers, pedophiles, and rioters

Coastline erosion due to rise in sea level greater than previously thought
The effects of coastline erosion as a result of rising sea-level rise can be measured by acceptable engineering tools, but such an erosion in the vicinity of inlets, such as river estuaries, has until now been underestimated – and more difficult to calculate; scientists have develop a new model to calculate this more complex erosion, making a valuable contribution to coastal management, planning, and infrastructure protection
