- Scientists show that cheap chemical dyes may one day help with the efficient capture of the sun's energy
- Bacteria that can "flip pancakes" with their DNA are the first microbes engineered to be living computers.
- A light microscope with high resolution may enable scientists to view the 3-D structures within living cells.
- New experiments have revealed an aerodynamic trick that dragonflies use to fly efficiently — a trick that engineers could exploit to improve the energy efficiency of small aerial vehicles with a similar design.
- Testing the toxicity of dozens of nanoparticles en masse may offer a faster track to medical applications.
- A new type of electronic component could shrink computer chips and make them more powerful.
- A more efficient material that converts heat into electricity could make a new kind of solar panel possible.
- New software pinpoints the weak spots in Michelangelo's David.
- Aerial surveys that scan the ground at many wavelengths, some visible and some not, may offer a way to quickly and easily detect mass grave sites.
- The quantum states of single diamond impurities work as magnetic sensors that could enable nuclear magnetic resonance to detect single atoms.
- Researchers have used DNA as Velcro to create the first materials that spontaneously assemble into regular 3-D patterns.
- By reshuffling the chemical letters of the genetic code, scientists have made short strands of DNA that can distinguish several different smells, such as explosives and food preservatives.
- A prototype memory chip stores data bits using carbon nanotubes as mechanical switches.
- Silicon nanowires can at least double the storage capacity of lithium-ion batteries.
- Magnetic nanoparticles selectively bind to specific bacteria and can drag them out of a liquid.
- Growing nanowires directly on a crystal might lead to high-density memory chips and transparent LEDs
- A novel sensor the size of a rice grain can detect magnetic fields as small as those produced by brain or heart waves.
- Despite computer models and wind tunnel tests, bridges show surprising vibrations and movements that engineers are still learning to cope with.
- Scientists filmed cage-shaped carbon molecules as they shrank to become buckyballs.
- Cleverly designed molecules can self-assemble into networks and stay robustly connected.
- Epidemiologists and social scientists are tapping into virtual online worlds inhabited by millions to collect data with real-world uses.
- Ordinary CD disc players can be adapted to perform chemical assays and possibly medical diagnoses.
- Coming to your tattoo parlor soon: New inks that allow clients to have their designs cleanly erased if embarrassment or regret sets in.
- A new technique for printing networks of carbon nanotubes on a wide range of surfaces is a step toward mass production of nanotubes devices.
- A new high-resolution printing technique could make flexible electronics such as plastic displays and solar cells easier to produce.
- Corn engineered to produce collagen may someday replace slaughterhouse leftovers as a source of gelatin.
- The events of 9/11 put new urgency into efforts to design buildings able to withstand the structural damage that fire can cause.
- A laser technique similar to a CAT scan produces 3-D images of living cells without the need for chemical staining.
