Mechanical loading is required for creating cartilage that is then turned to bone; however, little is known about cartilage development in the absence of gravity. Now, in a study led by the University of Missouri, bioengineers have determined that microgravity may inhibit cartilage formation. Findings reveal that fracture healing for astronauts in space, as well as patients on bed rest here on Earth, could be compromised in the absence of mechanical loading.
Researchers from North Carolina State University have developed a high-throughput technique that can determine if a chemical has the potential to activate key genes in seconds rather than the typical 24 hours or more. The technique can be used to prioritize chemicals for in-depth testing to determine their toxicity.
By capturing the crystal structure of RNA polymerase during a nontraditional form of transcription -- reiterative transcription -- researchers have identified a new pathway used by RNA to exit an enzyme.
ETH Zurich researchers have identified all the genes required by a bacterium to use methanol as a food source. The results will help scientists advance the use of this resource in the field of biotechnology.
A study led by researchers at Cedars-Sinai and NeuroVision Imaging LLC provides the scientific basis for using noninvasive eye imaging to detect the pathological hallmarks of Alzheimer's. The experimental technology, developed by Cedars-Sinai and NeuroVision, scans the retina using techniques that can identify beta-amyloid protein deposits that mirror those in the brain.
Photosynthesis provides energy for the vast majority of life on Earth. But chlorophyll, the green pigment that plants use to harvest sunlight, is relatively inefficient. To enable humans to capture more of the sun's energy, scientists have taught bacteria to cover themselves in tiny, highly efficient solar panels to produce useful compounds. The researchers are presenting their results at the 254th National Meeting & Exposition of the American Chemical Society.
In a new pair of papers, researchers from MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) explore ways for computers to help doctors make better medical decisions.
Fewer trips to the dentist may be in your future, and you have mussels to thank.
Given the possible security vulnerabilities related to developments in synthetic biology -- a field that uses technologies to modify or create organisms or biological components -- a new report by the National Academies of Sciences, Engineering, and Medicine proposes a framework to identify and prioritize potential areas of concern associated with the field.
A longstanding obstacle to the market for bovine embryos is about to be removed. Researchers have described a hitherto unknown mechanism of lipid accumulation in oocytes that limits the success of in vitro production of bovine embryos.
