We summarize the week's scientific breakthroughs every Thursday.
- Materials Science
Up to Snuff: Nanotube network fights flames
Researchers have found that infusing plastics with a network of carbon nanotubes reduces their flammability.
- Physics
Light Pedaling: Photonic brakes are vital for circuits
A novel silicon microchip device slows and varies light-pulse speeds—a function considered critical for the development of photonic circuits based on light instead of electrons.
- Physics
A matter of gravity
Gravity Probe B has finished its test of general relativity but results of the study won't be known for another year.
- Physics
Nanobots walk ‘n’ roll
A molecule that waddles on stubby feet and another that drives on ball-like wheels demonstrate scientists' increasing control over the usually haphazard motion of molecules on surfaces.
- Materials Science
Brainy bandages
Researchers have taken a step toward smart bandages that would indicate the presence of an infection in a wound.
- Materials Science
Slim and Sturdy Solar Cells: Nanocrystals offer path to electricity
Researchers have crafted an ultrathin solar cell out of inorganic nanocrystals that have several of the advantages of plastic but avoid some of its shortcomings.
- Materials Science
Explosive tempers
Researchers have demonstrated that carbon nanotubes, once ignited, can detonate explosives.
- Materials Science
Filling in the blanks
Scientists have added precision to a patterning technique called microcontact printing.
- Materials Science
Heart of the Matter: Scanning scope digs deeper into microchips
Researchers have developed a noninvasive imaging technique that lets them see deep inside a microchip.
- Materials Science
Carbon nanotubes get nosy
Researchers have demonstrated that individual nanotubes, decorated with DNA, can rapidly detect a number of gases.
- Physics
Transistor laser flaunts twin talents
A transistor that doubles as a laser can now operate at room temperature, bringing it to the verge of practical applications.
- Physics
Champion of strength is forged in mighty anvil
A new form of carbon created in an anvil and composed of microscopic needles of diamond has emerged as the strongest known material.
