NASA’s Human Research Program (HRP) uses research to develop methods to protect the health and performance of astronauts in space. In support of NASA’s goals for long-term missions on the surface of the Moon and human exploration of Mars, HRP is using ground research facilities, the International Space Station, and analog environments to monitor human health in deep space. NASA’s Artemis II mission was the first…
Hyundai has an answer if you love the Elantra N sports sedan but don’t think it’s quite sporty enough. The Korean badge has detailed pricing and specs for the 2026 Elantra N TCR Edition, a more track-ready version of its performance four-door.

More Information Log-Periodic Dipole Array (LPDA) fed parabolic reflector antennas serve high-gain broadband applications such as satellite communication, radio astronomy, and wideband radar, where constant performance over wide frequency ranges is essential. Despite nearly seven decades of research since the pioneering work of DuHamel and Ore in 1958, the synthesis and analysis of these antennas…
An emerging type of artificial intelligence, known as “agentic” AI, seems to do everything that biomedical scientists do—and often, does it faster. This next-generation technology can interpret experimental data, report the results and make decisions on its own. But is agentic AI smart enough to replace actual scientists?
