Assistant Professor Rob Viesca has a paper in the November issue of Nature Geoscience. Faults weaken during earthquakes. Analysis of the amount of energy released during earthquakes globally suggests that heat-induced pressurization of pore fluids can weaken faults during earthquakes of all sizes.
In an article in Chemical and Engineering News, Professor and Chair Kurt Pennell commented on how research in metabolomics methods can help address the “exposome”: the sum of environmental exposures a person experiences from conception until death. “Pennell’s goal is to relate exposome information to genetic information. In one study, his group is collaborating with researchers at Children’s Hospital in Boston to relate chemical exposure and whole-genome sequencing of mothers and children with autism spectrum disorder.”
Minnesota’s Duluth News Tribune reported on planned inspection of the state’s longest bridge with unmanned aerial vehicles. Associate Professor Babak Moaveni, chair of the ASCE SEI technical committee on Methods of Monitoring Structural Performance commented commented: “There is a huge need for better bridge-inspection techniques.”
As Optics and Photonics News states, “Current methods for shaping biomaterials, including soft- and photolithography, are limited to two dimensions and don’t offer much in the way of customization.” Tufts researchers, led by Associate Dean for Research and Professor, Fiorenzo Omenetto, “used low-energy (< nJ) femtosecond laser pulses to create 2-D and 3-D patterns in soft, transparent silk-protein hydrogels. They were able to achieve micromachining at a depth of 1 cm—reportedly more than 10 times deeper than any other biomaterial—at a lateral resolution of 5 µm.”
Details Daily Blog includes Tuft’s University discovery of a poly-silk bionink on their list of “10 Groundbreaking Innovations Changing How We Live”. This new discovery “will make printing tissues, organs, bone, and other organic materials a real possibility.”
CNBC highlights the accomplishments of 17-year-old Olivia Hallisey, “who designed a low cost, portable test for Ebola” and is the grand prize winner of the 2015 Google Science Fair. “Hallisey’s diagnostic for the Ebola virus offers results in less than 30 minutes and allows for rapid detection even when patients lack any symptoms. The design includes a silk-containing card that stores Ebola antibodies for up to a week without refrigeration.”
Biomedical engineering researches, funded by the National Institute of Biomedical Imaging and Bioengineering have “successfully developed a 3-dimensional (3D) tissue-engineered model of bone marrow that can produce functional human platelets outside the body (ex vivo)”, Health Medicine Network writes.
Tuft’s University biomedical engineers have been commended on Technology Networks article for their publication of the “first report of a promising new way to induce human mesenchymal stem cells to differentiate into neuron-like cells:treating them with exosomes.” Tufts Assistant Professor, Qiaobing Xu, is the paper’s senior and corresponding author.
Tufts Assistant Professor Qiaobing Xu and colleagues’ research on regenerative medicine using stem cells “is an increasingly promising approach to treat many types of injury” shares TuftsNow. “Transplanted stem cells can differentiate into just about any other kind of cell, including neurons to potentially reconnect a severed spinal cord and repair paralysis.”
