Biogen Idec said Monday the U.S. Food and Drug Administration (FDA) extended its review of Alprolix, a drug designed to treat hemophilia B. Biogen Idec said the FDA extended its review by three months. The move came after the agency asked Biogen for more information about validation of part of the Alprolix manufacturing process.
Research has shed new light on the properties of neutron stars, super dense stars that form when a large star explodes and collapses into itself. Writing in Nature, the team describes a newly discovered process that happens within the star's crust, located just below the surface. Until now, scientists thought that nuclear reactions within the crust contributed to the heating of the star's surface.
Dow Chemical is looking to separate about 40 manufacturing plants from its business as it continues to concentrate on moving away from cyclical commodity products. The company said it is considering joint ventures, spinoffs or sales. It expects those deals to happen within the next 12 to 24...
Nature builds flawless diamonds, sapphires and other gems. Now a Northwestern Univ. research team is the first to build near-perfect single crystals out of nanoparticles and DNA, using the same structure favored by nature. The research group developed the “recipe” for using nanomaterials as atoms, DNA as bonds and a little heat to form tiny crystals. This single-crystal recipe builds on superlattice techniques.
They are the coldest objects in the universe and are so fragile that even a single photon can heat and destroy them. Known as Bose-Einstein condensates (BECs) and consisting of just a cluster of atoms, it has up until now been impossible to measure and control these remarkable forms of matter simultaneously.
Splitting water into its components, two parts hydrogen and one part oxygen, is an important first step in achieving carbon-neutral fuels to power our transportation infrastructure. Now, North Carolina State Univ. researchers and colleagues from the Univ. of North Carolina at Chapel Hill have shown that a specialized coating technique can make certain water-splitting devices more stable and more efficient.
Humble aluminum’s plasmonic properties may make it far more valuable than gold and silver for certain applications, according to new research by Rice Univ. scientists. Because aluminum, as nanoparticles or nanostructures, displays optical resonances across a much broader region of the spectrum than either gold or silver, it may be a good candidate for harvesting solar energy and for other large-area optical devices and materials.
Lidar rangefinders gauge depth by emitting short bursts of laser light and measuring the time it takes for reflected photons to arrive back and be detected. In Science, researchers from Massachusetts Institute of Technology’s Research Laboratory of Electronics describe a new lidar-like system that can gauge depth when only a single photon is detected from each location.
Bruker Corp. has announced that it has been granted U.S. FDA clearance under Section 510(k) to market its MALDI Biotyper CA System in the United States for the identification of Gram negative bacterial colonies cultured from human specimens. The clearance marks progress in Bruker’s efforts to develop MALDI-TOF mass spectrometry into the most advanced platform for clinical microbiology identification.
The European Commission has approved the pending acquisition of Life Technologies Corp. by Thermo Fisher Scientific, which has committed to divest its cell culture (sera and media), gene modulation and magnetic beads businesses to expedite the approval. Combined, these businesses had 2012 revenue of approximately $225 million.
The presence of molecular hydrogen, in addition to carbon dioxide and water, could have created a greenhouse effect on Mars 3.8 billion years ago that pushed temperatures high enough to allow for liquid water. This is according to a team of researchers who believe this is the only way for giant canyons like Nanedi Valles could have formed.
Einstein@Home creates a global supercomputer by connecting more than 350,000 participants that contribute to a variety of scientific projects, particularly astronomy, by conducting distributed analysis routines with their home computers. This resource has already found several pulsars hidden in radio telescope data. Now, “citizen scientists” have helped researchers discover four new gamma-ray pulsars.
Univ. of Arizona agricultural and biosystems engineering associate professor Jeong-Yeol Yoon and cardiology professor Dr. Marvin Slepian are testing nanotextured surfaces to improve how cardiovascular implant devices are attached in the body. The goal is to create a selectively sticky surface, favoring endothelial cell attachment, without favoring platelet attachment.
In materials science, electric and magnetic effects have usually been studied separately. There are, however, extraordinary materials called “multiferroics”, in which electric and magnetic excitations are closely linked. Scientists in Austria have now shown in an experiment that magnetic properties and excitations can be influenced by an electric voltage.
Stuck inside on a rainy, dreary day in France, two physicists and an engineer stumbled on a television program about whirling dervishes. The film caused them to discuss structures with conical symmetry, or rotating flexible structures with a conical shape. Their thoughts have become the basis for a recent technical paper, which uses understandings of Coriolis force to develop simple explanatory equations.
