New research published in Ecology Letters offers an explanation for why numbers of many countryside bird species continue to decline, despite Government financial support for farmers to improve their habitat through agri-environment schemes.
Computer scientists are building mathematical models to represent the safest and most effective ways to perform surgery, including tasks such as suturing, dissecting and joining tissue.
About half of all children with Attention Deficit/Hyperactivity Disorder have difficulty making friends. A new clinical study is helping children with ADHD become better at making friends.
The proper processing of acoustic noise can provide a wealth of information. Geophysicists for example have used seismic background noise measurements to reconstruct the crustal structure under Southern California.
University of Pennsylvania alumni Ralph J. Roberts and his son Brian L. Roberts have pledged $15 million to help create the first-of-its-kind proton therapy center for the treatment of cancer.
A new Surgical Simulation and Technology Center at the University of Maryland Medical Center, one of only a few hospital-based centers of its kind in the United States, will open on December 6, 2006. The center brings together a diverse group of experts to solve important challenges in surgery, such as how to improve and expand minimally invasive surgical procedures that enhance patient care, how to advance the design of surgical instruments and how to redesign operating rooms to prevent surgeons from suffering from shoulder and neck injuries.
Researchers at the Georgia Institute of Technology have developed a technique to study how unicellular micro-algae, known as diatoms, create their complex cell walls. Researchers hope to learn how diatoms assemble these nanometer-patterned, intricate micro-architectures to find better methods for creating nanomaterials in the laboratory.
The two-slice-touch rule increased the accuracy of diagnosing meniscal tears, according to a study conducted by the Department of Radiology at the University of Wisconsin Medical School and Hospital, in Madison, Wis.
Vistasp Karbhari, a professor of structural engineering at UC San Diego, has developed fiber-reinforced polymer composites as strong, lightweight materials for aerospace, automotive, civil and marine applications, so he thought, “If they work so well in highway bridges, why not dental bridges.”
Mobile DNA, which inserts foreign genes into target cells, is a powerful force in the march of evolution and the spread of disease. Working with the lambda virus and E. coli bacteria, Brown University biologists have solved the structure of a six-protein complex critical to performing this gene-grafting surgery. The technique they developed could be used to reveal the structure of other critical protein complexes, landing the work on the cover of Molecular Cell.
