When trekking through a forest in French Guiana to study termites, a group of biologists noticed unique spots of blue on the backs of the insects in one nest. Curious, one scientist reached down to pick up one of these termites with a pair of forceps. It exploded. The blue spots, the team discovered, contain explosive crystals, and they're found only on the backs of the oldest termites in the colony. The aged termites carry out suicide missions on behalf of their nest mates.
After their initial observation, the team carried out field studies of Neocapritermes taracua termites and discovered that those with the blue spots also exploded during encounters with other species of termites or larger predators. The researchers found that the secretions released during the explosion killed or paralyzed opponents from a competing termite species. However, if the scientists removed the blue crystal from the termites, their secretions were no longer toxic.

Research finds that people with a wide range of microbes on their skin are less likely to attract mosquitoes.
Human skin is host to a wide range of microorganisms, many of which metabolize components in sweat to produce compounds that make up an individual’s specific body odor. The research findings suggest that how attractive you are to mosquitoes depends on your unique scent, or in other words, the diversity of your skin microbes.
Have you ever thought about how nutritious your bodily fluids are? Full of goodies like salts and proteins…Wild bees know all about it, feeding human sweat and tears as a source of nutrition. Urban sweat bees, for example, use humans like a salt lick. “These bees prefer sweaty people—over most animals—because the human diet usually is so salty that their perspiration is saturated with the essential nutrient,” according to a recent feature in the Wall Street Journal on sweat bees. A new species (Lasioglossum gotham) of these bees was recently identified from a specimen netted in the heart of Brooklyn. Although they are as a group fairly common, they’re tiny and they don’t sting, which is why you probably haven’t heard New Yorkers complaining about them.
Buildings would save energy on air conditioning if they installed smart windows that change color to block out sunlight on hot days. Some smart windows are on the market, but they are expensive. A new one-step method for making window coatings of transparent color-changing nanowires could simplify and bring down the cost of the window manufacturing process.
According to the National Renewable Energy Laboratory, buildings use 71% of the electricity consumed in the U.S.; about 30% of that load comes from the electricity needed to make up for energy lost through windows. Electrochromic windows, which darken or lighten depending on the voltage across them, could help by darkening to block heat transfer from infrared light.

Ramesh Raskar presents femto-photography, a new type of imaging so fast it visualizes the world one trillion frames per second, so detailed it shows light itself in motion. This technology may someday be used to build cameras that can look "around" corners or see inside the body without X-rays.
