For years, now, Pentagon-backed researchers have been trying to create cyborg insects that could serve as living, remote-controlled spies. The problem is, those modified bugs never survived long enough to be useful. Now, Georgia Tech professor Robert Michelson says he’s managed to get the bug ‘borgs to live into adulthood.

DARPA’s Hi-MEMS program aims to implant place micro-mechanical systems [MEMS] “inside the insects during the early stages of metamorphosis,” the agency explains. That way, as the bugs get older, tissues grow around — and fuse together with — the tiny machines.

Flight International reports that, in his latest work, Michelson truncated a Manduca moth’s thorax “to reduce its mass.” Then he put in “a MEMS component… where abdominal segments would have been, during the larval stage.” Continue reading »

Global warming could bring about a veritable insect explosion, if past performance is an indication of future gains.

Just such a buggy invasion swarmed parts of the northern United States during an abrupt global warming event more than 50 million years ago, a new study of leaf fossils shows.

The study’s findings, detailed in the Feb. 11 issue of the journal Proceedings of the National Academy of Sciences, indicate that the same thing could happen during our current period of warming.

This fossilized leaf shows where insects ate away at the plant some 50 million years ago during the Paleocene-Eocene Thermal Maximum.

During the Paleocene-Eocene Thermal Maximum more than 55 million years ago, insects chewed large holes in this leaf.

More than 55 million years ago, the Earth experienced a rapid jump in global carbon dioxide levels that raised temperatures across the planet. Now, researchers studying plants from that time have found that the rising temperatures may have boosted the foraging of insects. As modern temperatures continue to rise, the researchers believe the planet could see increasing crop damage and forest devastation. Continue reading »
