In July 1932, young pathology resident Elizabeth M. Ramsey was performing a routine autopsy with a colleague at New Haven Hospital when she made an extraordinary discovery: an apparently normal human ...

Earth System Models (ESMs) remain our primary tools for predicting future climate, yet they face significant challenges and uncertainties in reliably resolving the terrestrial carbon-water dynamics ...

Carnegie Science astronomers and engineers are redefining how we observe the universe by designing and building custom instruments for the telescopes at our Las Campanas Observatory in the Chilean ...

Most microalgae are obligate photoautotrophs and their growth is strictly dependent on the generation of photosynthetically derived energy. We show that the microalga Phaeodactylum tricornutum can be ...

The physics of planet formation is investigated using a population synthesis approach. We develop a simple model for planetary growth including pebble and gas accretion, as well as orbital migration ...

m We report the first detailed chemical abundances for five globular clusters (GCs) in M31 from high-resolution (R similar to 25,000) spectroscopy of their integrated light (IL). These GCs are the ...

Earth's atmospheric CO2 concentration (c(a)) for the Phanerozoic Eon is estimated from proxies and geochemical carbon cycle models. Most estimates come with large, sometimes unbounded uncertainty.

Water availability plays a critical role in shaping terrestrial ecosystems, particularly in low- and mid-latitude regions. The sensitivity of vegetation growth to precipitation strongly regulates ...

The 2024 Year Book reflects this continuum of discovery, highlighting the scientists driving today’s breakthroughs, honoring the legacies that shaped entire fields, and revealing the instruments and ...

A group of diseases have been shown to correlate with a phenomenon called microbiome dysbiosis, where the bacterial species composition of the gut becomes abnormal. The gut microbiome of an animal is ...

The Carnegie Supernova Project (CSP) was a five-year observational survey conducted at Las Campanas Observatory that obtained, among other things, high-quality light curves of similar to 100 ...

In this chapter, we present a review of experimental data in geochemistry used to place constraints on Earth's accretion and core formation. Siderophile element abundances combined with partitioning ...
