Biotechnology scientists must be aware of the broad patent landscape and push for new patent and licensing guidelines, according to a new paper from Rice University's Baker Institute for Public Policy.
With gene expression analysis growing in importance for both basic researchers and medical practitioners, researchers at Carnegie Mellon University and the University of Maryland have developed a new computational method that dramatically speeds up estimates of gene activity from RNA sequencing data.
Shape-memory polymers are an important class of materials in medicine, especially for minimally invasive deployment of devices. However, the rate of translation of the concept to approved products is extremely low. A paper described the general usefulness as well as the limitations of the shape-memory polymers for biomedical applications.
A football-shaped structure, known as the mitotic spindle, makes cell division possible for many living things. This piece of cellular architecture, responsible for dividing up genetic material, is in constant flux. The filaments that form it grow and shrink, while motor-like molecules burn energy pushing them about. To ensure the complex process proceeds in an orderly fashion, molecular fasteners pin the filaments together in certain places, and new research helps explain how they do it.
Droplets of filamentous material enclosed in a lipid membrane: these are the models of a 'simplified' cell used by the SISSA physicists Luca Giomi and Antonio DeSimone, who simulated the spontaneous emergence of cell motility and division - that is, features of living material - in inanimate 'objects'.
Photosynthesis provides fixed carbon and energy for nearly all life on Earth, yet many aspects of this fascinating process remain mysterious. We do not know the full list of the parts of the molecular machines that perform photosynthesis in any organism. A team developed a highly sophisticated tool that will transform the work of plant geneticists on this subject.
Scientists at the University of Basel report first ever successful nose reconstruction surgery using cartilage grown in the laboratory. Cartilage cells were extracted from the patient?s nasal septum, multiplied and expanded onto a collagen membrane. The so-called engineered cartilage was then shaped according to the defect and implanted.
Two new studies identify the processes and cellular pathways that allow cells to move, stiffen, and react to physical stresses. This knowledge, researchers hope, could reveal the causes of cancer and help develop treatments, including therapies for a variety of diseases.
Synthetic genetic circuitry created by researchers at Rice University is helping them see, for the first time, how to regulate cell mechanisms that degrade the misfolded proteins implicated in Parkinson's, Huntington?s and other diseases.
