  • Researchers are studying some common soil bacteria that "inhale" toxic metals and "exhale" them in a non-toxic form. The bacteria might one day be used to clean up toxic chemicals left over from nuclear weapons production decades ago.
  • By peering into the brain as it learns, scientists have found that the presence of a specific brain wave pattern predicts your ability to remember something. If it's there, you'll remember. If it's not, then, uh, you'll forget.
  • Video games that involve high levels of action, such as first-person-shooter games, increase a player's real-world vision, according to new research. The ability to perceive changes in shades of gray improves up to 58 percent.
  • Using aquatic microbes as their "canary-in-a-cage," scientists from Ohio are reporting that nanoparticles now being added to cosmetics, sunscreens, and hundreds of other personal care products may be harmful to the environment.
  • Mixing tea tree oil and silver greatly increases their antimicrobial activity and may minimise any side effects.
  • The intrinsic rotation of electrons -- the "spin" -- is a promising property for future electronics devices. Physicists have now succeeded in aligning electron spin, bringing it to a controlled "waver" and reading it out. The electron spin can also be realigned as required at any time using optical pulses.
  • A tiny microbe can take electricity and directly convert carbon dioxide and water to methane, producing a portable energy source with a potentially neutral carbon footprint, according to engineers. The process does not sequester carbon, but it does turn carbon dioxide into fuel, according to researchers.
