Stephanie Hampton

Aquatic ecologist Stephanie Hampton joined Carnegie as Deputy Director of Carnegie’s newly launched Division of Biosphere Sciences and Engineering at the end of July. She arrived from the National Science Foundation, where she was the director of the Division of Environmental Biology. She was also a professor and the former director of an interdisciplinary environmental research center at Washington State University.

India could be facing a water quality crisis as climate change affects the monsoon season, according to a new study from Carnegie’s Anna Michalak and Eva Sinha published in Environmental Science & Technology.

The first of six projects led by Carnegie-affiliated astronomers will, for the next three days, use the James Webb Space Telescope to make some of the most-accurate measurements ever taken of the chemistry of very early galaxies—studying light that traveled 10 billion years to reach us.

A 15-year study led by Carnegie’s Robert Hazen and Shaunna Morrison details the origins and diversity of every known mineral on Earth, a landmark body of work that will help reconstruct the history of life on our planet, guide the search for new minerals and ore deposits, predict possible characteristics of future life, and aid the search for habitable exoplanets and extraterrestrial life.

The violent event that likely preceded our Solar System’s formation holds the solution to a longstanding meteorite mystery, says new work from Carnegie’s Alan Boss published in The Astrophysical Journal.

Recent work from Carnegie’s Chenhui Wang and Allan Spradling reveals a surprising capability of renal stem cells in fruit flies—remodeling. Their work, which could eventually guide kidney stone treatments, was published by Science Advances.

The ancestors of some of the largest galaxy clusters have been hiding in plain sight. New work led by Carnegie’s Andrew Newman demonstrates a new technique for identifying the precursors of the most extreme galactic environments. The team’s findings are published in Nature

New work led by Carnegie’s Zhiyong Wang untangles a complex cellular signaling process that’s underpins plants’ ability to balance expending energy on growth and defending themselves from pathogens. These findings, published in Nature Plants, show how plants use complex cellular circuits to process information and respond to threats and environmental conditions.

New work led by Carnegie’s Petra Redekop, Emanuel Sanz-Luque, and Arthur Grossman probes the molecular and cellular mechanisms by which plants protect themselves from self-harm. Their findings, published by Science Advances, improve our understanding of one of the most-important biochemical processes on Earth.

A detailed analysis of the composition and motion of more than 500 stars revealed conclusive evidence of ancient a collision between Andromeda and a neighboring galaxy. The findings, which improve our understanding of the events that shape galaxy evolution, were presented by Carnegie’s Ivanna Escala Monday at the meeting of the American Astronomical Society.

As climate change shifts precipitation patterns, irrigation can be a powerful tool for increasing the world’s food supply—feeding more than a billion additional people without converting natural spaces into farmland, according to a new study by Carnegie’s Lorenzo Rosa published in Environmental Research Letters.

About 1.2 billion years ago a blue-green bacterium was engulfed by a more complex cell, transforming our planet and allowing a tremendous diversity of plant life to emerge and continue to evolve. This is the origin story for the generation of the cellular organelle responsible for photosynthetic activity, called the chloroplast. Although it is widely agreed upon to have occurred, there is still a great deal that scientists don’t understand about the process by which the cyanobacterium's genes were transferred, turning a symbiont into an organelle. Carnegie plant biologists Victoria Calatrava, Arthur Grossman, and Devaki Bhaya investigated.

Organisms grow to fit the space and resources available in their environments, leading to a vast diversity of body sizes and shapes within a population of the same species. What are the genetic and physiological mechanisms that determine how big an organism can grow? In insects and mammals, the cellular and molecular factors underpinning body size are well established. But in plants, this process has puzzled scientists for generations. How a plant controls the size to which it grows is a fundamental part of its developmental processes and impacts its likelihood of success in a particular environment.

A team of astronomers led by University of Michigan’s Ian Roederer and including Carnegie’s Erika Holmbeck have identified the widest range of elements yet observed in a star beyond our own Sun. Their findings are published in The Astrophysical Journal Supplement Series. The researchers identified 65 elements in the star, which is called HD 222925. Of these, 42 are from the bottom of the periodic table. Their identification will help astronomers understand one of the main methods by which the universe’s heavy elements were created—rapid neutron capture process.

We do not have any event for now.
