Animals like crickets use the ground to amplify calls      (via sciencedaily.com)     Original source 

When animals 'sing' sitting on the ground -- such as when crickets chirp -- their volume and reach increase dramatically, by as much as ten-fold. This result contradicts long-held beliefs in the field of animal communication, which presume the ground is a hindrance to sound transmission.

Predicting saltwater intrusion into groundwater using Plymouth, Mass. as test case      (via sciencedaily.com)     Original source 

As the world warms and ice sheets melt, the ocean continually rises. The greater Boston area can expect to see between one and six feet of sea level rise by 2100, according to recent estimates. To find out what this rise might mean for freshwater supplies, a team of hydrogeologists developed an innovative new model that can not only predict saltwater intrusion over the next 75 years, but also pinpoint the main sources of salt contamination today -- road salt and human development.

Stronger, stretchier, self-healing plastic      (via sciencedaily.com)     Original source 

An innovative plastic, stronger and stretchier than the current standard type and which can be healed with heat, remembers its shape and partially biodegradable, has been developed. They created it by adding the molecule polyrotaxane to an epoxy resin vitrimer, a type of plastic. Named VPR, the material can hold its form and has strong internal chemical bonds at low temperatures.
