The nuclear community has a high need for reliable and durable materials for core components of nuclear reactors — ScienceDaily

Texas A&M University researchers have recently shown superior performance of a new oxide dispersion strengthened (ODS) alloy they developed for use in both fission and fusion reactors. Dr. Lin Shao, professor in the Department of Nuclear Engineering, worked alongside research scientists at the Los Alamos National Laboratory and Hokkaido University to create the next generation of high-performance ODS alloys, and so far they are some of the strongest and best-developed metals in the field. ODS alloys consist of a combination…

Soft robot swims in the Mariana Trench

A team of researchers affiliated with multiple institutions in China has developed a soft robot that can successfully swim in the Mariana Trench. In their paper published in the journal Nature,, the group describes their soft robot and its capabilities. Cecilia Laschi and Marcello Calisti with the National University of Singapore and the University of Lincoln, respectively, have published a News & Views piece in the same journal issue outlining the work by the team in China. One of the…

5 Efficient Ways to Manage Your Factory

From a decrease in productivity to low turnover rates, managing a factory or a warehouse can be a daunting task. However, there are ways to develop your workplace into a rewarding and high-yielding business. Here are five efficient steps to help you manage your factory effectively. It may seem simple, but the most straightforward way to improve your management is by adding your employees to the conversation. Your factory workers know the ins and outs of their part in the…

Conntrack turns a blind eye to dropped SYNs

Intro We have been working with conntrack, the connection tracking layer in the Linux kernel, for years. And yet, despite the collected know-how, questions about its inner workings occasionally come up. When they do, it is hard to resist the temptation to go digging for answers. One such question popped up while writing the previous blog post on conntrack: “Why are there no entries in the conntrack table for SYN packets dropped by the firewall?” Ready for a deep dive…

Studies in mice show fat location matters for intermittent fasting — ScienceDaily

In a mouse study, Australian researchers have mapped out what happens behind the scenes in fat tissue during intermittent fasting, showing that it triggers a cascade of dramatic changes, depending on the type of fat deposits and where they are located around the body. Using state-of-the-art instruments, University of Sydney researchers discovered that fat around the stomach, which can accumulate into a ‘protruding tummy’ in humans, was found to go into ‘preservation mode’, adapting over time and becoming more resistant…

Color blindness-correcting contact lenses — ScienceDaily

Imagine seeing the world in muted shades — gray sky, gray grass. Some people with color blindness see everything this way, though most can’t see specific colors. Tinted glasses can help, but they can’t be used to correct blurry vision. And dyed contact lenses currently in development for the condition are potentially harmful and unstable. Now, in ACS Nano, researchers report infusing contact lenses with gold nanoparticles to create a safer way to see colors. Some daily activities, such as…

Mantis shrimp inspires new breed of light sensors

Inspired by the eyes of mantis shrimp, researchers have developed an optical sensor that is small enough to fit on a smartphone but capable of hyperspectral and polarimetric imaging. This image shows spectral imaging of a scene containing objects with different colors, as well as the letters NCSU, which contain different polarization states.

Jump-Start: Boosting VM performance – Facebook Engineering

What the research is: Jump-Start is a new approach for improving the performance of virtual machines at scale. Virtual machines are a modern and popular design to implement programming languages used to build applications in general, including large-scale websites like Facebook and Instagram. However, virtual machines incur well-known performance overhead in terms of the amount of memory and CPU resources required, particularly during the application’s warm-up phase, when the code is being profiled and translated from the virtual machine’s abstract…

Helping soft robots turn rigid on demand

Perhaps you’ve just conjured a machine with a rigid, metallic exterior. While robots armored with hard exoskeletons are common, they’re not always ideal. Soft-bodied robots, inspired by fish or other squishy creatures, might better adapt to changing environments and work more safely with people. Roboticists generally have to decide whether to…

Meet Shubhra Gangopadhyay – University of Missouri College of Engineering

Sometimes, before you can think big, you have to think small. After all, you can’t tackle the big problems without interacting with the microscopic molecules, electrons and atoms that make up our world. Meet Shubhra Gangopadhyay, professor, researcher and inventor of teeny-tiny technologies. Gangopadhyay has built a career around detecting and interacting with nanoparticles. Today, she is C.W. LaPierre Endowed Chair Professor in the Department of Electrical Engineering and Computer Science and Co-Director of the Center for Nano/Micro Systems and…
