Marine reserves are increasingly important for species that are being forced by climate change to move to a new home, adapt to new conditions or die. Stanford biologist Steve Palumbi compares the relative benefits of large and small protected areas in perpetuating populations. He also has found a coral species that has developed the “skills” [...]

By dipping ordinary paper or fabric in a special ink infused with nanoparticles, Stanford engineer Yi Cui has found a way to cheaply and efficiently manufacture lightweight paper batteries and supercapacitors (which, like batteries, store energy, but by electrostatic rather than chemical means), as well as stretchable, conductive textiles known as “eTextiles” — capable of [...]

Since the dawn of the biological sciences, humankind has struggled to comprehend the relationships among the major groups of “jointed-legged” animals — the arthropods. Now, a team of researchers, including Dr. Joel Martin and Dr. Regina Wetzer from the Natural History Museum of Los Angeles County (NHM), has finished a completely new analysis of the [...]

At the quantum level, the forces of magnetism and superconductivity exist in an uneasy relationship. Superconducting materials repel a magnetic field, so to create a superconducting current, the magnetic forces must be strong enough to overcome the natural repulsion and penetrate the body of the superconductor. But there’s a limit: Apply too much magnetic force, [...]

When NASA’s satellite operators need accurate, real-time space-weather information, they turn to the Community Coordinated Modeling Center (CCMC) of the Space Weather Laboratory at NASA’s Goddard Space Flight Center in Greenbelt, Md. The CCMC’s newest and most advanced space-weather science tool is the Integrated Space Weather Analysis (iSWA) system.

Knowing the stage of a patient’s melanoma is important when choosing the best course of treatment. When the cancer has progressed to the lymph nodes, a more aggressive treatment is needed. Examining an entire lymph node for cancer takes much effort and time; a new technique might help make the process more efficient. University of [...]
