Metabolic diseases like diabetes and obesity are closely linked with several female reproductive disorders. A team of Carnegie biologists homes in on how eggs store fuel for embryonic development what this can teach us about female infertility.
Baltimore, MD— Reproduction is highly dependent on diet and the ability to use nutrients to grow and generate energy. This is clearly seen in women, who must provide all the nutritional building blocks required to support a growing embryo. As a result, metabolic diseases like diabetes and obesity...

Stanford, CA— You’ve probably seen news stories about the highly lauded, much-discussed genome editing system CRISPR/Cas9. But did you know the system was actually derived from bacteria, which use it to fight off foreign invaders such as viruses? It allows many bacteria to snip and store segments of DNA from an invading virus, which they can then use to “remember” and destroy DNA from similar invaders if they are encountered again.
Scientists have long been puzzled by Mercury’s very dark surface. Previously, scientists proposed that the darkness came from carbon accumulated by comet impacts. Now scientists, including Carnegie’s Larry Nittler, confirm that carbon is present at Mercury’s surface, but that it most likely originated deep below the surface, in the form of a now-disrupted and buried ancient graphite-rich crust, which was later brought to the surface via impacts after most of the current crust formed.
Metallic glasses are at the frontier of materials science research. They have been made by rapidly cooling alloys of various metals including, zirconium, palladium, iron, titanium, and copper, and used for a variety of applications from making golf clubs to aerospace construction. But much about them remains poorly understood. A team of scientists from Carnegie's Geophysical Laboratory is trying to unravel the mysteries of metallic glass.

Baltimore, MD—New work from Carnegie’s Allan Spradling and Lei Lei demonstrates that mammalian egg cells gain crucial cellular components at an early stage from their undifferentiated sister cells, called germ cells. This mechanism had previously only been documented in lower animals, and may be a key to understanding the egg’s unique properties. Their work is published via Science First Release.

Washington, D.C.—For the first time scientists have looked at the net balance of the three major greenhouse gases—carbon dioxide, methane, and nitrous oxide—for every region of Earth’s landmasses. They found surprisingly, that human-induced emissions of methane and nitrous oxide from ecosystems overwhelmingly surpass the ability of the land to soak up carbon dioxide emissions, which makes the terrestrial biosphere a contributor to climate change.
The Energy Frontier Research in Extreme Environments Center (EFree) was established to accelerate the discovery and synthesis of kinetically stabilized, energy-related materials using extreme conditions.
