Viesca Publishes in Nature Geoscience

Robert C. Viesca

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.

Pennell Comments on Metabolomics Methods and the ‘Exposome’ in CE&N

Kurt D. Pennell

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.”

Germaine Delivers First BSCES Ladd Memorial Lecture

John (Jack) Germaine

Research Professor Jack Germaine was chosen as the inaugural speaker for the Boston Society of Civil Engineers Section’s first Charles C. Ladd Memorial Lecture. His lecture covers trends in mechanically compressed sediment behavior with stress and plasticity.

Moaveni Comments on UAV Bridge Inspection

Babak Moaveni

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.”

Femtosecond Lasers Shape Biomaterials for Tissue Engineering

Fiorenzo Omenetto

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.”

10 Groundbreaking Innovations That Are Changing How We Live

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.”

Researchers develop 3D bone marrow that produces functional human platelets ex vivo

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.


New Way To Repair Nerves

Qiaobing Xu

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.


Secretary of Defense Acknowledges Fisher’s Anti-Hacking Research

Kathleen FisherU.S. Secretary of Defense Ash Carter acknowledged the role that Professor Kathleen Fisher played in the creation of the High-Assurance Cyber Military Systems (HACMS) program at the Defense Advanced Research Projects Agency (DARPA).
Secretary Carter opened DARPA’s “Wait What?” Future Technology Forum in St. Louis by discussing some of the technological advances made through programs such as HACMS.
“After years in a corporate-research lab, [Fisher] came to DARPA on a three-year tour in 2011, where she launched a program that uses so-called formal methods to make certain software, like the code behind physical control systems of an airplane or a self-driving car, to help them become mathematically provably unhackable,” said Carter.

Biopsies Without Knives

Irene Georgakoudi

Irene Georgakoudi, associate professor of biomedical engineering at Tufts University is researching methods “to diagnose cancer at a cellular level, well before it grows into a visible lesion or tumor.”, shares TuftsNow“Although her techniques aren’t yet ready for clinical use, Georgakoudi is hopeful they could make a dramatic impact on the way cancers are identified—turning a dreaded disease into something that can be managed and treated before it spirals out of control.”
