New material could efficiently power tiny generators

October 22, 2009

To power a very small device like a pacemaker or a transistor, you need an even smaller generator. The components that operate the generator are smaller yet, and the efficiency of those foundational components is critical to the performance of the overall device. Read More

War of the viruses: Could ancient virus genes help fight modern AIDS?

October 20, 2009

Almost 30 years into the AIDS epidemic, scientists have yet to find an effective vaccine against HIV, the virus that destroys the immune system and causes AIDS. HIV is perhaps the most adaptive virus ever seen, not only evading the immune system, but also antiviral medicines. Read More

High-speed genetic analysis looks deep inside primate immune system

October 11, 2009

Viruses such as HIV and influenza take safe harbor in cells, where they cannot be recognized directly by the immune system. The immune response relies on infected cells announcing the presence of the virus by studding their exterior with fragments of the virus lurking within. Read More

The strikingly banded rocks scattered across the upper Midwest and elsewhere throughout the world are actually ambassadors from the past, offering clues to the environment of the early Earth more than 2 billion years ago. Read More

Scientists hope to mimic nature’s dynamos

October 9, 2009

In the cosmos, all celestial objects - planets, stars, galaxies and clusters of galaxies - have magnetic fields. On Earth, the magnetic field of our home planet is most easily observed in a compass where the needle points north. Read More
