NUS historian of science Dr John van Wyhe has co-published a groundbreaking new book on Charles Darwin which shows for the first time the extent of his cultural impact over the past 160 years. A decade in the making, this volume demonstrates that Darwin is the most influential scientist who has ever lived, having the most species named after him and he is also the most translated scientist in history.
Scholarship and Practice of Undergraduate Research Issue Features Nontraditional Approaches to Research
The winter 2020 issue of Scholarship and Practice of Undergraduate Research (SPUR), the academic journal of the Council on Undergraduate Research, focuses on unusual approaches to undergraduate research such as research for chefs and a video game for biology majors.
Scientists have long used information from sediments at the bottom of the ocean to reconstruct the conditions in oceans of the past. But a study in Science Advances raises concerns about the common use of pyrite sulfur isotopes to reconstruct Earth’s evolving oxidation state. These signals aren’t the global fingerprint of oxygen in the atmosphere, according to new research from Washington University in St. Louis.
PNNL researchers discover a new route to forming complex crystals
How did rocks rust on Earth and turn red?

Volcanologists from the University of Georgia and two Swiss universities found a link between carbon dioxide and the volume of gas trapped in magma, which could help predict the intensity and magnitude of a volcanic eruption.
There isn’t much in Kamchatka, a remote peninsula in northeastern Russia just across the Bering Sea from Alaska, besides an impressive population of brown bears and the most explosive volcano in the world. Kamchatka’s Shiveluch volcano has had more than 40 violent eruptions over the last 10,000 years.

Diverse microbes discovered in the clay-rich, shallow soil layers in Chile’s dry Atacama Desert suggest that similar deposits below the Martian surface may contain microorganisms, which could be easily found by future rover missions or landing craft.
Humankind’s next giant step may be onto Mars. But before those missions can begin, scientists need to make scores of breakthrough advances, including learning how to grow crops on the red planet.
Deep-seated landslides in the central Oregon Coast Range are triggered mostly by rainfall, not by large offshore earthquakes.
Victoria Orphan is the James Irvine Professor of Environmental Science and Geobiology in the Division of Geological and Planetary Sciences at the California Institute of Technology.
It’s one of the best-known geological heritage sites around the world, filled with fossils and glacial secrets. Now, thanks to virtual reality technology, the ice-age past of Hallett Cove Conservation Park is revealed in a new, gamified VR experience – Beyond the Ice – and is launched this week as part of National Science Week.
Geologists from Florida State University’s Department of Earth, Ocean and Atmospheric Science have discovered how carbon-rich molten rock in the Earth’s upper mantle might affect the movement of seismic waves.
Climate records from a cave in the southern Great Basin show that Nevada was even hotter and drier in the past than it is today, and that one 4,000-year period in particular may represent a true, “worst-case” scenario for the Southwest and the Colorado River Basin — and the millions of people who rely on its water supply.
In a new study in the journal Gondwana Research demonstrated that the Carnian Pluvial Episode affected the southern hemisphere, specifically South America, which strengthens the case that it was a global climate event.

Studies have shown the Arctic is warming roughly twice as fast as the rest of the world, and its soil holds twice the amount of carbon dioxide as the atmosphere. New research from San Diego State University finds that water from spring snowmelt infiltrates the soil and triggers fresh carbon dioxide production at higher rates than previously assumed.
Uncovering what drives the evolution of new animals is key for understanding the history of life on Earth. Geologist James Lamsdell is embarking on this exploration as a recipient of the National Science Foundation’s CAREER award.

The study, published in Nature, was conducted by a team of international resources, including two from Tulane University.
Geologists studied exposed, 3.2-billion-year-old ocean crust in Australia and used that rock data to build a quantitative, inverse model of ancient seawater. The model indicates the early Earth could have been a “water world” with submerged continents.
New research on sand dunes in China describes how even neighboring dunes can long remain in different and seemingly conflicting states — confounding the assessment of stabilization efforts and masking the effects of climate change.
“Geology is a 3D science, but everything we give to students is on a 2D piece of paper,” says University at Buffalo geologist Chris Lowry, creator of the Foldable Aquifer Project. “With the foldable aquifers, students don’t have to imagine what a 2D drawing looks like in 3D.”
