Innovation Has Two I’s, Just Like The Humans It Empowers

Posted by in categories: business, innovation

Rob Tillman, CIO of Copy Chief, has 20+ years transforming businesses with a human-centric innovation model deployed across diverse sectors.

In today’s fast-paced digital age, the term “innovation” is frequently thrown around in boardrooms, tech conferences and startup pitches. It’s often hailed as the driving force behind progress and the competitive edge for businesses. But have we ever paused to truly understand what innovation means at its core?

It’s not just about creating groundbreaking technologies or pioneering novel solutions. At its heart, innovation is about empowering humans.

Imaging brain tissue architecture across millimeter to nanometer scales

Posted by in categories: mapping, nanotechnology, neuroscience, robotics/AI

Another excellent paper from Johann G. Danzl’s research group. They develop methods that combine novel negative staining techniques, deep learning, and super-resolution STED microscopy or expansion microscopy to facilitate nanoscale-resolution imaging of brain tissue volumes. They also show semi-automated (and some fully automated) segmentation of neuron morphology and identification of synapses. Very cool work and I’m excited to see how it influences connectomics in the future! #brain #neuroscience #imaging #microscopy #neurotech

Nanoparticles Stopping Metastases in Its Tracks

Posted by in categories: biotech/medical, chemistry, nanotechnology

An international research team headed by Johannes Karges, PhD, of the faculty of chemistry and biochemistry at Ruhr University Bochum, Germany, has developed nanoparticles that accumulate in cancer cells and eliminate them after being photoactivated. The research team also labeled them in such a way that immune cells learn to eliminate similar cells throughout the body which could even mean undetected metastases can be treated.

The researchers presented their findings in the journal Nature Communications in an article titled, “Theranostic imaging and multimodal photodynamic therapy and immunotherapy using the mTOR signaling pathway.”

“Tumor metastases are considered the leading cause of cancer-associated deaths,” the researchers wrote. “While clinically applied drugs have demonstrated to efficiently remove the primary tumor, metastases remain poorly accessible. To overcome this limitation, herein, the development of a theranostic nanomaterial by incorporating a chromophore for imaging and a photosensitizer for treatment of metastatic tumor sites is presented. The mechanism of action reveals that the nanoparticles are able to intervene by local generation of cellular damage through photodynamic therapy as well as by systemic induction of an immune response by immunotherapy upon inhibition of the mTOR signaling pathway which is of crucial importance for tumor onset, progression, and metastatic spreading.”

Global Connectivity Predicts Reactivity

Posted by in categories: materials, particle physics

If you could quickly predict the reactivity of a material in different scenarios using only its atomic-level geometry, you’d hold the golden ticket to finding application-specific catalytic materials. Some methods exist for making these predictions, but they require detailed knowledge about the arrangement of the atoms and are computationally expensive to perform and thus slow to run. Now Evan Miu and his colleagues at the University of Pittsburgh have developed a method that requires only information about the connectivity of the atoms, is computationally cheap, and is quick to run [1]. Their method accurately predicts how metal oxides interact with hydrogen in a reaction important to energy storage and catalysis.

Miu and the team hypothesized that they could predict a material’s reactivity using a single number that describes the so-called global connectivity of the system’s atoms. A material with a high global connectivity contains atoms that are, on average, bonded to more of their neighbors than does a system with a low value of this parameter. The researchers have used a similar concept to study reactivity for metal catalysts, but not for more complex structures, such as metal oxides.

To test their idea, the researchers examined—in different metal oxides—so-called hydrogen intercalation, a type of redox reaction that alters the host material’s properties. They found that they could use each oxide’s global connectivity to determine the strength of its hydrogen reactivity. The model-determined values for the various hydrogen-binding energies agree with experimental data and took mere seconds to obtain. The tool could thus allow scientists to rapidly develop and optimize novel materials to use in energy-storage applications.

Why Seawater Is Foamy

Posted by in category: futurism

Observations of air-bubble mergers in water explain why dissolved salt slows this process and leads to foam.

Air bubbles churned up in pure water can easily merge. But bubbles merge far more slowly in seawater or in other liquids containing dissolved impurities, which is why such liquids often generate enduring foams. Now a team of engineers believes that it has identified the fundamental cause of the difference—subtle forces set up by electrolytes, mobile ions created when substances dissolve in liquids [1]. In a collision between two bubbles, these forces greatly reduce the rate at which the liquid separating the bubbles can flow away. This understanding, the researchers say, explains why foams arise so easily in salty seawater and could be useful in many industrial applications.

Solutions with high electrolyte concentrations often produce persisting foams, so researchers have suspected for decades that dissolved electrolytes somehow slow bubble mergers. The effect has remained mysterious, however, and many theories even suggest that electrolytes should speed up bubble mergers, says mechanical engineer Bo Liu of the University of Alberta in Canada.

‘Brainless’ robot can navigate complex obstacles

Posted by in category: robotics/AI

Researchers who created a soft robot that could navigate simple mazes without human or computer direction have now built on that work, creating a “brainless” soft robot that can navigate more complex and dynamic environments. The paper, “Physically Intelligent Autonomous Soft Robotic Maze Escaper,” was published Sept. 8 in the journal Science Advances.

“In our earlier work, we demonstrated that our was able to twist and turn its way through a very simple obstacle course,” says Jie Yin, co-corresponding author of a paper on the work and an associate professor of mechanical and at North Carolina State University. “However, it was unable to turn unless it encountered an obstacle. In practical terms this meant that the robot could sometimes get stuck, bouncing back and forth between parallel obstacles.
