Of the 92 naturally occurring elements, add another to the list of those that are superconductors.James S. Schilling, Ph.D., professor of physics in Arts & Sciences at Washington University in St. Louis, and Mathew Debessai "” his doctoral student at the time "” discovered that europium becomes superconducting at 1.8 K (-456 °F) and 80 GPa (790,000 atmospheres) of pressure, making it the 53rd known elemental superconductor and the 23rd at high pressure.Debessai, who...

Material scientists at Washington University in St. Louis have developed a technique for a bimetallic fuel cell catalyst that is efficient, robust and two to five times more effective than commercial catalysts. The novel technique eventually will enable a cost effective fuel cell technology, which has been waiting in the wings for decades, and should give a boost for cleaner use of fuels worldwide.Younan Xia, Ph.D., the James M. McKelvey Professor of Biomedical Engineering at Washington...

Tutoring children in and after school isn't new, but how much does it really help in critical areas like reading? Rigorous new research from Washington University in St. Louis shows significant gains from a national service program that trains experienced Americans to help low-income children one-on-one in urban public schools. The central finding: Over a single school year, students with Experience Corps tutors made over 60 percent more progress in learning two critical reading skills...

'Taco shell' proteinResearchers at Washington University in St. Louis have figured out the orientation of a protein in the antenna complex to its neighboring membrane in a photosynthetic bacterium, a key find in the process of energy transfer in photosynthesis.Robert Blankenship, Ph.D., Markey Distinguished Professor of biology and chemistry in Arts & Sciences, led a team that for the first time combined chemical labeling with mass spectroscopy to verify the orientation. The team also...

New spin on laser-flash analysis Putting a new spin on an old technique, Anne M. Hofmeister, Ph.D., research professor of earth and planetary sciences in Arts & Sciences at Washington University in St. Louis, has revolutionized scientists' understanding of heat transport in the Earth's crust, the outermost solid shell of our planet. Temperature is an important driver of many geological processes, including the generation of magmas (molten rocks) in the deepest parts of the Earth's crust,...

Pediatric surgeons are able to repair complex heart defects with a survival rate of greater than 90 percent, but that doesn't necessarily mean a happy ending for these children and teens. Some may have a great quality of life and others, with the same condition, may not.A study conducted at seven pediatric medical centers throughout the United States shows that several categories of patients with heart disease, including African-Americans and lower-income families, have a lower quality of...

Kind of a drag Last summer, it was very expensive to fill up a gas tank when the gasoline price hit close to four dollars a gallon. Transportation by road or air consumes fuel, which not only increases our vulnerability to foreign imports but also is a source of greenhouse gas emissions that will impact adverse change in climate and global warming. A mechanical engineer at Washington University in St. Louis is developing techniques that will lessen our monetary pain at the pump by reducing...

The rotating black hole has been described as one of nature's most perfect objects. As described by the Kerr solution of Einstein's gravitational field equations, its spacetime geometry is completely characterized by only two numbers "” mass and spin "” and is sometimes described by the aphorism "black holes have no hair.'' A particle orbiting a rotating black hole always conserves its energy and angular momentum, but otherwise traces a complicated twisting rosette pattern with no...
