‘True polar wander’ may have caused ice age

JADE BOYD – NOVEMBER 19, 2018 Rice U. scientists use Hawaiian hot spot to study movement of Earth’s poles Earth’s latest ice age may have been caused by changes deep inside the planet. Based on evidence from the Pacific Ocean, including the position of the Hawaiian Islands, Rice University geophysicists have determined Earth shifted relative […]

Ice-age climate clues unearthed

Rice scientist’s method helps interpret climate data from lake sediments MIKE WILLIAMS – OCTOBER 24, 2018 How cold did Earth get during the last ice age? The truth may lie deep beneath lakes and could help predict how the planet will warm again. Sediments in lake beds hold chemical records of ages past, among them the […]

Tiny northwest quakes tied to deep-crust structure

MIKE WILLIAMS – OCTOBER 25, 2018 Rice University scientists uncover relationship between tremors, water at the Cascadia margin HOUSTON – (Oct. 25, 2018) – The earthquakes are so small and deep that someone standing in Seattle would never feel them. In fact, until the early 2000s, nobody knew they happened at all. Now, scientists at Rice […]

What recipes produce a habitable planet?

JADE BOYD – SEPTEMBER 17, 2018 Cross-disciplinary team will track life-essential elements during planets’ early evolution NASA’s interdisciplinary Nexus for Exoplanet System Science (NExSS) project has awarded Rice University $7.7 million for a multidisciplinary, multi-institutional research program aimed at finding many different recipes nature might follow to produce rocky planets capable of supporting life. As any […]

Pedram Hassanzadeh named Gulf Research Program Early-Career Research Fellow

ARIE PASSWATERS – AUGUST 29, 2018 Adrienne Correa, assistant professor of biosciences at Rice, and Pedram Hassanzadeh, assistant professor of mechanical engineering and of Earth, environmental and planetary sciences, received 2018 Early-Career Research Fellowships from the Gulf Research Program, part of the National Academies of Sciences, Engineering and Medicine. The fellowships support emerging scientific leaders as they take risks […]

Kilauea eruption an opportunity for undersea scrutiny

  Video by Rice Professor Julia Morgan, taken from a helicopter on July 16, shows lava from the ongoing eruption of Kilauea on the Big Island of Hawaii as it moves from the volcano to the sea. Morgan and her colleagues spent a week placing ocean-bottom seismic instruments off the southeastern shore of the island. […]

Sulfur analysis supports timing of oxygen’s appearance

River water helps Rice U. scientist support rise of atmospheric oxygen 2.7 billion years ago By Mike Williams HOUSTON – (July 23, 2018) – Scientists have long thought oxygen appeared in Earth’s lower atmosphere 2.7 billion years ago, making life as we know it possible. A Rice University researcher has added evidence to support that […]
