Solar panels convert visible light from the sun into electricity—but the sun's infrared light passes right through the panel's silicon material. Using a new all-metal structure, Caltech researchers have come up with a method that may be able to harness that lost energy.

A team of researchers has discovered an ancient, deep canyon buried along the Yarlung Tsangpo River in south Tibet. The geologists say that the ancient canyon—thousands of feet deep in places—effectively rules out a popular model used to explain how the massive and picturesque gorges of the Himalayas became so steep, so fast.

Two and a half billion years ago, single-celled organisms called cyanobacteria harnessed sunlight to split water molecules, producing energy to power their cells and releasing oxygen into an atmosphere that had previously had none. These early environmental engineers are responsible for the life we see around us today, and much more besides. At 8:00 p.m. on Wednesday, November 19, in Caltech's Beckman Auditorium, Professor of Geobiology Woodward "Woody" Fischer will describe how they transformed the planet. Admission is free.

Using a new analytical technique, Caltech researchers studying the rock record uncover new information about the sulfur cycle on early Earth and what that could mean for the rise of oxygen in the atmosphere.

Methane-breathing microbes that inhabit rocky mounds on the seafloor could be preventing large volumes of the potent greenhouse gas from entering the oceans and reaching the atmosphere, according to a new study by Caltech researchers.

The effect could be as strong as those due to the wind and tides, the main factors that are known to drive the up-and-down mixing of oceans.

In the typical textbook picture, volcanoes, such as those that are forming the Hawaiian islands, erupt when magma gushes out as narrow jets from deep inside Earth. But that picture is wrong, according to a new study.

This summer, Caltech junior Kevin Li has been working with computational scientists and seismologists to refine the Community Seismic Network (CSN) by developing a machine-learning system that can accurately estimate the magnitude of an earthquake within seconds of its detection.
