Proposición de modelo computacional para la enfermedad de Alzheimer
Los investigadores de Mayo Clinic propusieron un nuevo modelo para hacer un mapa de los síntomas de la enfermedad de Alzheimer en la anatomía cerebral. El modelo se creó mediante la aplicación de aprendizaje automático a los datos de imágenes cerebrales de los pacientes.
Comparing African and European populations leads to breast cancer risk discovery
By comparing genetic data from European and African population groups, scientists at UChicago Medicine Comprehensive Cancer Center have identified seven new regions of the human genome that are associated with increased breast cancer risk. The findings were published in Nature Communications.
Mayo researchers, collaborators identify ‘instigator’ gene associated with Alzheimer’s disease
In a new paper published in Nature Communications, Mayo Clinic researchers and collaborators report the protein-coding gene SERPINA5 may worsen tau protein tangles, which are characteristic of Alzheimer’s disease, and advance disease. By combining clinical expertise, brain tissue samples, pathology expertise and artificial intelligence, the team clarified and validated the relevance of the gene to Alzheimer’s disease.
NAU study indicates that U.S. cities underestimate their greenhouse gas emissions by nearly 20 percent on average
Some cities’ self-reported emissions are as much as 145 percent below standardized estimates, distorting the data on which climate change policy actions are based.
Atomic fingerprint identifies emission sources of uranium
Uranium is not always the same: depending on whether this chemical element is released by the civil nuclear industry or as fallout from nuclear weapon tests, the ratio of the two anthropogenic, i.e. man-made, uranium isotopes 233U and 236U varies. These results were lately found by an international team grouped around physicists from the University of Vienna and provides a promising new “fingerprint” for the identification of radioactive emission sources.
A new form of glass through molecular entanglement
Physicists at the University of Vienna in collaboration with the Max Planck Institute for Polymer Research have discovered a new type of glass formed by long, cyclic molecules. The scientists successfully demonstrated that by making parts of the rings more mobile, the rings become more strongly entangled and the molecular fluid glassifies.
