Flexible impedance sensor can fit inside urinary catheters; monitor and treat biofilm

Credit: A. James Clark School of Engineering, University of Maryland A long-term, interdisciplinary research collaboration at the University of Maryland’s A. James Clark School of Engineering has made significant progress in detecting and treating bacterial biofilms by developing new chemical compounds, materials, and microsystems that can fight these sources of post-operative infections. In their 10-year collaboration, Professor Reza Ghodssi (Department of Electrical and Computer Engineering; Institute for Systems Research), Professor William Bentley (Fischell Department of Bioengineering; Robert E. Fischell Institute…

Decline in atmospheric carbon dioxide key to ancient climate transition — ScienceDaily

A decline in atmospheric carbon dioxide (CO2) levels led to a fundamental shift in the behaviour of the Earth’s climate system around one million years ago, according to new research led by the University of Southampton. A team of international scientists used new geochemical measurements, coupled with a model of the ‘Earth system’, to show that the growth and changing nature of continental ice sheets, approximately a million years ago, coincided with a cascade of events that ultimately lowered atmospheric…

A hard material engineers hope to make harder

For thousands of years, people have built civilizations with concrete made from readily available local materials. Just mix and heat, add some sand, stone and water and put it where you want it. Of course, give it time to harden – that is, after you have left your hand print or initials. So it’s no surprise that concrete is the world’s most widely used building material. Twice as much concrete has been used to build Pittsburgh – and everything else…

Engineering Ethics Blog: What Price Medicine?

Last week I had the privilege of attending the American Physical Society Texas Section’s annual regional meeting, held this year at the campus of the University of Texas at Dallas.  Among several invited speakers was a professor of radiology who spoke about the latest medical imaging techniques being developed for observing biological activity on the molecular level.  As interesting as that was, I want to focus on an offhand remark the speaker made.  He has many friends in the medical…

Is 3-D printing living up to the hype?

Credit: CC0 Public Domain The growth in 3-D printing is allowing manufacturers to reduce production time and save money. Metal fabrication shops, industrial firms and engineers are also capitalizing on the technology. But the predicted mass production of 3-D printed products for consumers has not yet come to pass. An article in Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society, explains how industry is using the technology. Over the past decade, 3-D printing has been…

Researchers discover that surface polarization in mixed media increases attraction among elements — ScienceDaily

Despite their name, rare earth elements actually aren’t that rare. Abundant in mines around the world, rare earths are used in many high-tech products, including visual displays, batteries, super conductors, and computer hard drives. But while they aren’t necessarily tricky to find, the elements often occur together and are extremely difficult to separate and extract. “Having the ability to recover rare earths is important because they are finite but in high demand,” said Northwestern University’s Monica Olvera de la Cruz.…

A fashionable chemical and biological threat detector-on-a-ring

A first-of-its kind ring sensor can detect chemical and biological threats. Credit: American Chemical Society Wearable sensors are revolutionizing the tech-world, capable of tracking processes in the body, such as heart rates. They’re even becoming fashionable, with many of them sporting sleek, stylish designs. But wearable sensors also can have applications in detecting threats that are external to the body. Researchers now report in ACS Sensors a first-of-its kind device that can do just that. And to stay fashionable, they’ve…

Mars study yields clues to possible cradle of life — ScienceDaily

The discovery of evidence for ancient sea-floor hydrothermal deposits on Mars identifies an area on the planet that may offer clues about the origin of life on Earth. A recent international report examines observations by NASA’s Mars Reconnaissance Orbiter (MRO) of massive deposits in a basin on southern Mars. The authors interpret the data as evidence that these deposits were formed by heated water from a volcanically active part of the planet’s crust entering the bottom of a large sea…

Project reveals benefits of communicating with industry when conducting research

A new paper describes the importance of doing detailed economic analysis and having in-depth conversations with people using the technology that a research project is focused on.

Left background image by Shreya Dave When Shreya Dave was an MIT doctoral student working on a new kind of filter for desalination plants, she paid a visit to a working reverse-osmosis desalination plant in Spain. She quickly learned an important lesson that she now says she would likely have…
