We’ve gotten pretty good at turning solar power into electricity, but electricity can be hard to store, making it a challenge for use right when you need it and in the transportation sector.
Engineers at Caltech have hacked an inexpensive microscope, turning it into a billion-pixel imager that makes even the best standard microscopes pale in comparison.One of the most fundamental truths in microscopy is that you can have either high resolution images of a small area or low resolution views ...
Chemists at the California Institute of Technology (Caltech) and the Lawrence Berkeley National Laboratory say they can now explain one of the remaining mysteries of photosynthesis, the chemical process by which plants convert sunlight into usable energy and generate the oxygen that we breathe.
Astronomers have found the strongest evidence yet that the ocean on Jupiter's moon Europa may consist of salty water, like our own. And, they say, that salty water appears to be making its way to the surface.
A big problem with the use of electric rocket engines known as Hall thrusters has been erosion of their discharge channel walls, limiting their use to the inner solar system.
Scientists say they've built a proof-of-concept device that could become the memory or processing element for an on-chip optical quantum network.
The 'stable' zones thought to inhibit nearby earthquakes may actually make them worse, a new study shows, implying that California's San Andreas fault may be much more dangerous than believed.
There are at least 100 billion planets in the Milky Way alone, say Caltech scientists, based on extrapolations from the Kepler-32 system.
Smartphones could be equipped to see through solid objects, say Caltech electrical engineers, who have developed tiny, inexpensive terahertz imagers.
New research indicates that life might be able to survive on some of the odder exoplanets discovered so far - from scorching hot worlds with molten surfaces to freezing balls of ice.
Scientists have created a free-swimming 'jellyfish' out of silicone seeded with living heart muscle cells.
By 2100, nearly 40 percent of land-based ecosystems - forest, grassland or tundra, for example - will have moved from one type to another.
Caltech researchers have created the first artificial neural network from DNA - a circuit of interacting molecules that can recall memories based on incomplete patterns, just as a brain can.
Caltech researchers have built the most complex biochemical circuit ever, creating a DNA computer that can calculate square roots.
Caltech researchers have built a device that produces highly focused, high-amplitude acoustic signals dubbed 'sound bullets'.
