The navigational skills of bacteria inspire robotics researchers
Humans may regret this, but bacteria have superior survival skills; bacteria are not the only organisms that travel in swarms — fish, bees, and birds also exhibit collective navigation; bacteria, however, have superior survival tactics and such tactics may be inspire better robot design

Double whammy: dinosaurs killed by massive volcanoes, meteorite impacts
The mass extinction of the dinosaurs, which occurred at the end of the Cretaceous period sixty-five million years ago, was the result not of one catastrophic event (meteorite strike) but rather the result of a catastrophic one-two punch: colossal volcanic eruptions and meteorite strikes

Europe faces rare Earth metal shortages
The EU’s ambitious low-carbon energy production goal depends on five technologies: nuclear, solar, wind, bio-energy, and carbon capture; these technologies, in turn, depend on rare Earth metals; the EU estimates that a large-scale deployment of only one of these technologies — solar energy — will require half the current world supply of tellurium and 25 percent of the supply of indium

Ionized plasmas as cheap sterilizer in tough places
Scientists show that ionized plasmas like those in neon lights and plasma TVs not only can sterilize water, but make it antimicrobial; these plasma devices could be life-savers in developing countries, disaster areas, or on the battlefield where sterile water for medical use is in short supply and expensive to produce

Nature inspires advances in ultrasound technology
Sonar and ultrasound, which use sound as a navigational device and to paint accurate pictures of an environment, are the basis of many technologies, including medical ultrasound machines and submarine navigation systems; when it comes to more accurate sonar and ultrasound, however, animals’ “biosonar” capabilities still have the human race beat – but not for long

Rebuilding dried-up swamps to protect New Orleans from hurricanes
During the past four decades, swamps and wetlands which used to offer New Orleans a natural defense against hurricane, were dried and paved over. The city has launched a new project to restore a key area of cypress swampland near the Lower 9th Ward, an effort they called essential to protecting the metro area in the event of another major hurricane.

White House: no evidence of, contact with extra terrestrials
Two petitions, signed by 17,000, were submitted to the White house; the first demanded immediate disclosure of the U.S. government’s knowledge of and communications with extraterrestrial beings, the second a formal acknowledgement from the White House that extraterrestrials have been engaging the human race; in response, the White House Office of Science & Technology Policy wrote that the U.S. government has no evidence that any life exists outside our planet, or that an extraterrestrial presence has contacted or engaged any member of the human race
