In April, a team from Glasgow School of Art will shoot lasers at the heads of George Washington, Abraham Lincoln, Teddy Roosevelt, and Thomas Jefferson. And they will do it all in the name of preservation.

The Scottish artists have perfected a system of laser scanning giant monuments, ensuring the digital preservation of even their finest nooks and crannies. They have already completely digitized Scottish landmarks like Rosslyn Church and Stirling Castle. The team is also working in conjunction with CyArk, a non-profit dedicated to laser scanning 500 UNESCO world heritage sites.

A new "genomic zoo" has launched, with the goal of sequencing the genomes of 10,000 vertebrate species. The project aims to help researchers understand recent and rapid adaptive changes among the species. It could also allow predictions of how certain species might respond to climate change, pollution, new diseases and competitors.

The Genome 10K Project will scour zoos, museums and universities worldwide for thousands of specimens. An international coalition of more than 68 scientists has outlined their plans in a paper that will appear tomorrow in the Journal of Heredity.

About halfway through our cover story on the next generation of manned submarines, you'll find a provocative dispute between two legendary figures over the respective merits of manned and unmanned exploration of the ocean.

Going green makes military sense to the U.S. Army. Self-sufficient vehicles and base camps require fewer supply convoy runs that stretch logistics lines thin across hostile territory. The Army's new "zero-footprint" concept for a camp includes a package of very cool technologies.

Soldiers could eventually obtain their drinking water from vehicle exhaust, based on water-purification technologies being developed by the U.S. Army's TARDEC and DARPA labs. Garbage and waste produced by camps could also become new sources of energy.

Trees are great absorbers of carbon dioxide from the atmosphere, and inhibitors of climate change -- that's why treehuggers hug them so much. But leave it to humanity to engineer a better tree. A synthetic tree, currently being tested as a prototype, ensnares carbon about 1,000 times faster than a real tree.

The water toilet is truly one of the greatest miracles of modern life, a frothy disappearing act; now you see it… now you don’t. But washing human waste away requires huge sewage treatment infrastructures in cities, and extensive home septic systems for rural dwellers. Compost toilets, though in their essence as old as human civilization, have evolved to a point of technological sophistication whereby they tackle the minutiae of composting details to create optimal conditions for recycling human waste.

Take a look at the compost toilet tech out there for the non-flushers among us.
