Precisely fitting bone implants from the printer

Plasma-jet coating of medical implant scaffolds. Credit: Fraunhofer IST, Falko Oldenburg Cancerous tumors, infections or bad fractures can make it necessary to surgically remove bones and insert implants in their place. In collaboration with European partners, Fraunhofer researchers have now developed a technique with which bone implants that are precisely fitting, stable and variable in dimensions can be 3-D printed from a special plastic. The secret lies in the printing process, where the individual layers are treated with a cold…

Creating digital twins of materials

Data spaces can be used to integrate all types of materials information into digital networks – a valuable tool for production in the context of Industrie 4.0. Credit: Fraunhofer IWM To ensure the digital networking of production systems and the optimization of material-specific requirements, we need to measure, analyze and replicate the changes in material properties in a process in which “digital twins” of materials are created. The materials data space developed by Fraunhofer researchers has laid the groundwork for…

Novel color sensors are less expensive to manufacture

FOWINA – accurate micro color sensors for chip-level integration. Credit: K. Selsam, Fraunhofer ISC In the FOWINA project, the Fraunhofer Institute for Integrated Circuits IIS in Erlangen and the Fraunhofer Institute for Silicate Research ISC in Würzburg have developed novel color sensors with a special microlens arrangement. The sensors can be realized directly on the chip and combine multiple functions in a minimum of space. Their extremely slim design makes the sensors suitable for a wide range of applications, such…

Marriott's Data Breach: Not In Our Line of Work

Back when I attended Cornell for my master’s degree, I learned that one of the stronger academic programs on campus was what is now called the Cornell School of Hotel Administration.  There was even an actual hotel on campus run by undergrads in the program, and reportedly (I never stayed there) it was one of the best hotels in Ithaca, and quite reasonably priced.  But this was back in the days when guests registered by signing a physical registration blank,…

How engineers are straightening the Leaning Tower of Pisa

Still beautifully oblique “It’s still straightening,” said engineer Roberto Cela, gazing at the Leaning Tower of Pisa gleaming in the autumn sunshine of northern Italy. “And many years will have to pass before it stops.” The gravitationally-challenged landmark is leaning less after years of ambitious engineering work. Fortunately for the millions of tourists who come here every year, the 57-metre (186-feet) tower remains beautifully askance. The medieval bell tower, a symbol of the power of the maritime republic of…

Global trial shows CAR T therapy can lead to durable remissions in non-Hodgkin’s lymphoma — ScienceDaily

In an update to a global clinical trial stretching from Philadelphia to four continents, the chimeric antigen receptor (CAR) T cell therapy Kymriah® (tisagenlecleucel, formerly CTL019) led to long-lasting remissions in patients with relapsed/refractory (r/r) diffuse large B-cell lymphoma (DLBCL). The most recent results from the trial will be presented today at the 60th American Society of Hematology (ASH) Annual Meeting and Exposition in San Diego. Stephen J. Schuster, MD, director of the Lymphoma Program at the Abramson Cancer Center…

Using AI and satellite imagery for disaster insights

WHAT THE RESEARCH IS: A framework for using convolutional neural networks (CNNs) on satellite imagery to identify the areas most severely affected by a disaster. This new method has the potential to produce more accurate information in far less time than current manual methods. Ultimately, the goal of this research is to allow rescue workers to quickly identify where aid is needed most, without relying on manually annotated, disaster-specific data sets. HOW IT WORKS: Researchers train models on CNNs to…

Pursuit of Excellence banquet celebrates success, inclusivity

Dean Loboa (far right) joined the winners of the 1907 Women in Engineering Awards, given at Thursday’s second-annual Pursuit of Excellence Banquet. The Mizzou Engineering Office of Diversity and Outreach Initiatives and the MU Center for Academic Excellence and Success hosted the second-annual Pursuit of Excellence Banquet on Thursday in Columbia. The banquet celebrates outstanding students, faculty and staff from Mizzou Engineering who are from traditionally underrepresented backgrounds in engineering and those who work to support their efforts. A variety…

Researchers bring Jedi powers to life with Force Push

Force Push is a novel VR technique that allows users to move objects with unprecedented nuance. Credit: Virginia Tech In the interim, stalwart practitioners of Jedi ways and other Force-sensitive beings can look to the small screen and thank Virginia Tech researchers for a recently developed virtual reality technique called Force Push. Force Push gives its users the ability to move faraway objects with Yoda-like calm, nuance, and focus using an approach for remote object manipulation in VR. “You…

‘Sudoku’ X-Ray uncovers movements within opaque materials — ScienceDaily

When strolling along the beach, our footprints tell us that the sand under the surface must have moved but not precisely where or how. Similar movements occur in many other natural and human-made substances, such as snow, construction materials, pharmaceutical powders, and even cereals. To examine these largely unknown granular movements, academics from the Sydney Centre in Geomechanics and Mining Materials (SciGEM) including Professor of Civil Engineering, Itai Einav and Postdoctoral Research Associate, Dr James Baker have developed a new…
