The push for renewable energy has led to the generation of biofuels from cellulose-rich biomass, algae, and crops. Currently, crop-based biofuels are limited to those derived from agricultural products: corn, soybean, rapeseed, and surgarcane. An increase in the demand for crop-based biofuels will require either an increase in the amount of agricultural land or an increase in crop production on existing land.
An expansion of agricultural land can only occur if whatever is presently on the land is sacrificed—this can mean abandoned lands, pastures, or natural systems. Natural systems such as grasslands and forests store large amounts of carbon; if turned into agricultural lands, this carbon could be released into the atmosphere. Though crops also store carbon as biomass during their growth, regular harvests do not allow for long-term carbon storage. From a climate perspective, this could be problematic.
Do the carbon and nitrogen emissions that result from the deforestation and land-use intensification offset the environmental benefits of displacing fossil fuels? One way to assess this issue is by calculating carbon payback times, which represent the period over which the total greenhouse gas savings due to the displacement of fossil fuels equals the initial losses in ecosystem carbon stocks caused by land conversion.

While it’s certainly not the longest, this weight-bearing structure is definitely one of the more interesting bridges we’ve come across. Unveiled earlier this month, PaperBridge is the latest site-specific installation by environmental artist Steve Messam. It was constructed using 22,000 sheets of bright, red paper. And despite weighing in at over 4.2 tons, the free-standing structure doesn’t have a single screw, bolt or swab of glue holding it together.
On an aesthetic level, PaperBridge acts as focal point that creates a stark contrast between the bridge and the lush landscape. But on a conceptual level, Messam explains the key relationship between the bridge and its surroundings:
Paper is a simple material made from wood pulp and water. The intensity of colour used in the bridge contrasts with the verdant landscape making a bold statement of form and design. Alongside this the materials used have a resonance with the natural environment and the construction of the bridge also reflects local architectural forms, specifically pack horse bridges found throughout the area. All of the paper used in PaperBridge will be recovered and returned to the Burneside Mill for recycling into new paper once the project ends. This transparent cycle is part of the overall environmental narrative of the piece.
PaperBridge was part of the ‘Lakes Ignite’ project. It was located in the Grisedale Valley, near Patterdale and the public was invited to walk across it before it gets taken down today. (via Designboom and The Kid Should See This)

The trap-jaw ant has a won notorious reputation in the insect kingdom for its super-strong, spring-loaded mandibles, which it uses to crush prey with ease and defend its nests.
However, a new study, reported in PLOS ONE, has revealed a whole new use for its impressive jaws: flinging itself out of "death traps" set by predators.
Research carried out by Fredrick Larabee and Andrew Suarez, entomologists from the University of Illinois at Urbana-Champaign, compounds earlier findings from 2006, which showed that trap-jaw ants could use their lightning-fast mouths for "ballistic jaw propulsion"—in short, opening their jaws to 180 degrees before snapping them shut at 140 miles per hour.
