Discovery Could Help Stop Malaria at Its Source — the Mosquito
August 29, 2007: As summer temperatures cool in the United States, fewer mosquitoes whir around our tiki torches. But mosquitoes swarming around nearly 40 percent of the world’s population will continue to spread a deadly parasitic disease — malaria. Now an interdisciplinary team led by researchers from Rensselaer Polytechnic Institute has found a key link that causes malarial infection in both humans and mosquitoes. |

Beyond Batteries: Storing Power in a Sheet of Paper
August 13, 2007: Researchers at Rensselaer have developed a new energy storage device that easily could be mistaken for a simple sheet of black paper. The nanoengineered battery is lightweight, ultra thin, completely flexible, and geared toward meeting the trickiest design and energy requirements of tomorrow’s gadgets, implantable medical equipment, and transportation vehicles. |

Graphene Nanoelectronics:
Making Tomorrow’s Computers from a Pencil Trace
July 23, 2007: Saroj Nayak, associate professor of physics, has worked with graduate student Philip Shemella and others for two years to determine how graphene’s extremely efficient conductive properties can be exploited for use in nanoelectronics. After running dozens of robust computer simulations, the group has demonstrated for the first time that the length, as well as the width, of graphene directly impacts the material’s conduction properties. |

Tough Tubes: Carbon Nanotubes Endure Heavy Wear and Tear
July 2, 2007: The ability of carbon nanotubes to withstand repeated stress yet retain their structural and mechanical integrity is similar to the behavior of soft tissue, according to a new study. When paired with the strong electrical conductivity of carbon nanotubes, this ability to endure wear and tear, or fatigue, suggests the materials could be used to create structures that mimic artificial muscles or interesting electro-mechanical systems. |

Undifferentiated Networks Would Require Significant Extra Capacity
June 29, 2007: A new study by researchers at Rensselaer, AT&T Labs, and the University of Nevada, Reno suggests that an Internet where all traffic is treated identically would require significantly more capacity than one in which differentiated services are offered. |

Nanotube Adhesive Sticks Better Than a Gecko’s Foot
June 18, 2007: Mimicking the agile gecko, with its uncanny ability to run up walls and across ceilings, has long been a goal of materials scientists. Researchers at Rensselaer and the University of Akron have taken one sticky step in the right direction, creating synthetic “gecko tape” with four times the sticking power of the real thing. |

Nano Technique Allows Precise Injection of Living Cells
June 14, 2007: Specialized pulsed lasers have been used to inject individual cells with a variety of materials, but little is known about how this type of injection might affect living cells. For the first time, researchers at Rensselaer have analyzed this nanoscale injection process on living cells and discovered that minor changes in the intensity of the laser could mark the difference between a healthy cell and a dead one. |

The Original Nano Workout: Helping Carbon Nanotubes Get Into Shape
June 6, 2007: Researchers at Rensselaer have developed a new method of compacting carbon nanotubes into dense bundles. These tightly packed bundles are efficient conductors and could one day replace copper as the primary interconnects used on computer chips and even hasten the transition to next-generation 3-D stacked chips. |
