Researchers studying iron-based superconductors are combining novel electronic structure algorithms with the high-performance computing power of the Titan supercomputer to predict spin dynamics, or the ways electrons orient and correlate their spins in a material.
Hollow coring drills designed and managed by UW-Madison’s Ice Drilling Design and Operations (IDDO) program are used to extract ice cores that can analyze the past atmosphere. Shaun Marcott, an assistant professor of geoscience at UW-Madison, was the first author of a paper published today in the journal Nature documenting carbon dioxide in the atmosphere between 23,000 and 9,000 years ago, based on data from an 11,000-foot hole in Antarctica.
Mimicking natural evolution in a test tube, scientists at The Scripps Research Institute have devised an enzyme with a unique property that might have been crucial to the origin of life on Earth.
Scores of autoimmune diseases afflicting one in 12 Americans — ranging from type 1 diabetes, to multiple sclerosis (MS), to rheumatoid arthritis, to asthma — mysteriously cause the immune system to harm tissues within our own bodies. Now, a new study pinpoints the complex genetic origins for many of these diseases, a discovery that may lead to better diagnosis and ultimately to improved treatments.
Two major genetic studies of autism, led in part by UC San Francisco scientists and involving more than 50 laboratories worldwide, have newly implicated dozens of genes in the disorder. The research shows that rare mutations in these genes affect communication networks in the brain and compromise fundamental biological mechanisms that govern whether, when, and how genes are activated overall.
Scientists using the Atacama Large Millimeter/submillimeter Array (ALMA) have detected a streamer of dust and gas flowing from a massive outer disk toward the inner reaches of a binary star system. This never-before-seen feature may be responsible for sustaining a second, smaller disk of planet-forming material that otherwise would have disappeared long ago.
Newfound Genetic Differences Provide Many Hints at Causes
A new study on a large cohort of kidney cancer patients in Europe sheds light on the genetic architecture of the disease -- and reveals an apparent link between exposure to aristolochic acid and incidence of kidney cancer, particularly in Romania.
We’re more likely to punish wrongdoing as a third party to a non-violent offense than when we’re victimized by it, according to a new study by New York University psychology researchers. The findings may offer insights into how juries differ from plaintiffs in seeking to restore justice.
Amoebas aren’t the only cells that crawl: Movement is crucial to development, wound healing and immune response in animals, not to mention cancer metastasis. In two new studies from Johns Hopkins, researchers answer long-standing questions about how complex cells sense the chemical trails that show them where to go — and the role of cells’ internal “skeleton” in responding to those cues.
Astronomers at Georgia State University’s Center for High Angular Resolution Astronomy (CHARA) have observed the expanding thermonuclear fireball from a nova that erupted last year in the constellation Delphinus with unprecedented clarity.
Using CRISPR, researchers at MIT's Koch Institute have developed a new approach to rapidly model the effects of tumor cells’ genetic mutations in mice.
