Researchers at the University of Florida have built a 300-foot experimental runway to study the effects of lightning strikes on existing runway lighting systems. The runway, equipped with various lighting systems, will be struck by lightning-induced electrical discharges from rockets launched into dark skies.
A handheld laser device can detect sickle-cell anemia and track cell structure changes, distinguishing between cancerous and non-cancerous cells. The device is expected to reduce analysis time for victims of terrorist biological or chemical attacks, facilitating prompt treatment.
Researchers have created a new tool to correct distortions in microscopes, allowing for enhanced resolution and accuracy in studying tiny surfaces. The innovation uses an electron mirror to cancel aberrations caused by lenses, leading to practical applications such as smaller miniature probes and improved instruments.
Researchers have discovered a powerful energy source inside the nucleus of a Seyfert galaxy, challenging previous theories and providing new insights into the formation of galaxies. The findings suggest that both types of Seyfert galaxies may harbor quasars, with the power source located behind an obscuring 'fat torus' or doughnut girdle.
