Brown dwarfs are sometimes called failed stars. They’re stars’ dim, low-mass siblings and they fade in brightness over time. They’re fascinating to astronomers for a variety of reasons, but much about them remains unknown.
Andrew Carnegie understood that science is unpredictable. He created the institution to support individuals of exceptional ability and passion and gave them the independence to pursue high-risk, high-reward science.
Stanford, CA— Algae may hold the key to feeding the world’s burgeoning population. Don’t worry; no one is going to make you eat them. But because they are more efficient than most plants at taking in carbon dioxide from the air, algae could transform agriculture. If their efficiency could be transferred to crops, we could grow more food in less time using less water and less nitrogen fertilizer.
Washington, DC— New work from Carnegie’s Peter Driscoll suggests Earth’s ancient magnetic field was significantly different than the present day field, originating from several poles rather than the familiar two. It is published in Geophysical Research Letters.
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, DC— It turns out that forests in the Andean and western Amazonian regions of South America break long-understood rules about how ecosystems are put together, according to new research led by Carnegie’s Greg Asner and published in the Proceedings of the National Academy of Sciences. Their findings could help scientists understand how tropical forests will respond to global climate change.
