(Ecole Polytechnique Fédérale de Lausanne) EPFL scientists have found that the activity of proprotein covertases, the enzymes that turn-on proteins, is regulated by the location of the enzyme inside the cell. Published in Cell Reports, the study uses a novel biosensor, CLIP, and has significant implications for cancer treatment.
(King Abdullah University of Science & Technology (KAUST)) A nanomaterial coating enables efficient delivery of CRISPR-Cas9 machinery into the cell.
(Florida Institute of Technology) Using 1,310 base pairs of two mitochondrial genes, Toby Daly-Engel, an assistant professor of biological sciences at Florida Tech, and colleagues identified a new species, the Atlantic sixgill shark...
(University of Nebraska-Lincoln) All extreme-altitude birds have evolved especially efficient systems for delivering scarce oxygen to their tissues. But a new study led by the University of Nebraska-Lincoln has found that these birds often evolved different blueprints for assembling the proteins -- hemoglobins -- that actually capture oxygen in the Himalayas and Andes.
(Georgia Institute of Technology) The pursuit of the usual suspect in Alzheimer's research may be distracting from a more direct culprit in the disease, according to a study that analyzed data from 51 published experiments. P-tau looked a good bit more culpable than amyloid-beta plaque.
(Institute for Research in Biomedicine (IRB Barcelona)) Researchers headed by Jordi Casanova at the Institute for Research in Biomedicine (IRB Barcelona) now demonstrate that genes activated during metastasis are also able to initiate primary tumour development, and they explain the molecular mechanism involved.

(Friedrich-Schiller-Universitaet Jena) Protein nanofibres often have outstanding properties such as a high stability, biodegradability, or antibacterial effect. Artificially creating these fibres is not easy, much less assigning them specific functions. Show More Summary
(University of Johannesburg) Researchers can now remove the anxiety drug Diazepam from recycled water and wastewater, using low-cost titanium dioxide nanofibers. First marketed as Valium, Diazepam is available in hundreds of brands.Show More Summary
(Universitat Autonoma de Barcelona) A research study by the Universitat Autònoma de Barcelona (UAB) in collaboration with the University of La Laguna (ULL) demonstrates in mice the biological relevance of sex in the effects of accelerated ageing caused by a chronic treatment of D-galactose.
(University of Exeter) Problem-solving powers may help to explain why grey squirrels have taken over from native red squirrels in the UK, new research says.
(Forschungsverbund Berlin) Most ion channels are very selective about the ions, which may or may not pass through them. They may be conductive for potassium ions and non-conductive for sodium ions or vice versa. However, a number of ion channels allows for the efficient passage of both kinds of ions. Show More Summary
(ARC Centre of Excellence in Coral Reef Studies) New research has revealed the tiny minority of fishers who poach on the Great Barrier Reef (GBR) think the illegal practice is justified, because they believe 'everyone else is doing it.'
(Write Science Right) Researchers at UFRGS and the US NIH have targeted proteins that regulate chromatin in Ewing sarcoma cells, hindering malignant tumor growth. They induced chromatic relaxation by treating the cells with histone deacetylase...Show More Summary
(University of California - San Diego) Overfishing and environmental change have pushed abalone species on the US west coast to the edge of extinction. Now a fatal disease threatens their recovery. But new research shows that some abalone...Show More Summary
(Hokkaido University) Very long-chain lipids in the most superficial layer of the tear film cause severe dry eye disease when they were shortened in mice -- a result that could help develop new drugs for the disease.
(Medical College of Georgia at Augusta University) What do bad sleep habits and stiff blood vessels have in common?Nothing good, say scientists exploring what appears to be a direct connection between a circadian clock that isn't working as it should and an enzyme that promotes inflammation working overtime.
(Biophysical Society) A cell's membrane is composed of a bilayer of lipids, and the inside-facing layer is made of different lipids than the outside-facing layer. Because different lipids create membranes with different physical properties,...Show More Summary
(Lund University) Nocturnal animals can use the stars and the Milky Way to find their way during the darkest hours. While animal navigation is studied all over the world, some of the leading researchers are based at Lund University in Sweden. In a recent article they sum up the research so far and give their thoughts on challenges to come.
(Barcelona Institute for Global Health (ISGlobal)) A study published in the European Respiratory Journal has shown that both moderate and severe exacerbations in COPD patients are associated with a decline in their physical activity level. Researchers observed tha the acute drop in physical activity during a COPD exacerbation has an important and lasting effect.
(Helmholtz Zentrum München - German Research Center for Environmental Health) Researchers from the Helmholtz Zentrum München at the University Hospital Carl Gustav Carus of TU Dresden together with colleagues from Rockefeller University New York succeeded for the first time in the visualization of the insulin receptor activation.
