A diagram illustrating the makeup of the implants

Imagine if there were a remote-control electronic device that could be implanted at an infection site, where it would treat the infection by heating or medicating the affected tissue. While it might be very effective, subsequent infections could result if surgeons went in to remove it, or even if they just left it in place. That's why scientists from Tufts University and the University of Illinois at Champaign-Urbana have developed infection-treating implants that simply dissolve into the body once they've served their purpose.  Read More

UAVs could someday be used to prevent bridge collapses, such as this one in Minneapolis  (...

When bridges are inspected for cracks and other defects that could lead to their collapse, engineers must either hang beneath those bridges on lines, or view them from elevated platforms. Whichever approach is used, a lot of setup is involved, and defects may get missed. In the future, however, unmanned aircraft may be able to more quickly and thoroughly check out bridges, working with wireless sensors built into the structures.  Read More

Confocal microscope image of the artificial neural tissue developed at Tufts University

One approach to studying the brain rather than working on the whole thing at once is to examine small bits of it. With that in mind, researchers at the Tissue Engineering Resource Center at Tufts University, Boston have developed a three-dimensional brain-like tissue that is structurally similar to living rat brain tissue, functions enough like it for experimental purposes, and one that scientists have been able to keep alive for up to two months.  Read More

A group of researchers from Tufts University, Brown University and the Rensselaer Polytechnic Institute are collaborating with the US Navy in a multi-year effort to explore how they might create robots endowed with their own sense of morality. If they are successful, they will create an artificial intelligence able to autonomously assess a difficult situation and then make complex ethical decisions that can override the rigid instructions it was given.  Read More

Protein from silkworm cocoons has been used to create strong yet biodegradable bone fixati...

Silk is an amazingly strong material, yet it also harmlessly biodegrades when left in the body. This has led to its use in experimental brain implants, heart patches, and even bio-electronics. According to a new study conducted by scientists at Tufts University School of Engineering and Beth Israel Deaconess Medical Center, it may now also find use in the production of better plates and screws used for securing broken bones.  Read More

The Uji shower head starts out green, and gradually changes to red

There are few things that most of us like better than a long, hot shower, but they sure use up a lot of water and power. That’s why Tufts University grads Brett Andler, Sam Woolf and Tyler Wilson have created the Uji illuminated shower head. It gradually changes from green to red while in use, letting users know when it’s time to get out.  Read More

The bioskiving process (Image credit: Qiaobing Xu)

Collagen is the main component of connective tissues and the most abundant protein in the human body. Biocompatible and biodegradable, it is an excellent material for making scaffolding for tissue engineering. The trouble is, conventional techniques disrupt the fibrous structure of collagen and weaken the end product. Tufts University researchers are aiming to change this with a new technique for fabricating collagen structures that avoids disruption and retains collagen’s strength.  Read More

We’ve certainly been hearing a lot lately about tiny electronic devices that can do things such as delivering medication after being implanted in the body, measuring structural stress upon being attached to a bridge, or monitoring pollution after being placed in the environment. In all of these cases, the device has to be retrieved once it’s served its purpose, or just left in place indefinitely. Now, however, an interdisciplinary team of researchers have demonstrated “transient electronics,” which dissolve into nothing after a pre-determined amount of time.  Read More

Brainput provides a passive, implicit input channel to interactive systems, with little ef...

As machines get more and more sophisticated, the mental capacity of their human overlords stays at a static (albeit seemingly impressive) level, and therefore slowly starts to pale in comparison. The bandwidth of the human brain is not limitless, and if an overloaded brain happens to be overseeing machines carrying out potentially dangerous tasks, you can expect trouble. But why had we built the machines in the first place, if not to save us from trouble? Brainput, a brain-computer interface built by researchers from MIT and Tufts University, is going to let your computer know if you’re mentally fit for the job at hand. If it decides your brain is overloaded with tasks, it will help you out by handling some of them for you.  Read More

Scientists have created microneedles made from silk, which are said to offer several advan...

Microneedles continue to show promise as a replacement – in at least some applications – for the hypodermic needle. Typically, a sheet containing an array of the tiny needles is adhered to the patient’s skin, like a bandage. The microneedles painlessly pierce the top layer of skin, then gradually deliver the medication within them by harmlessly dissolving into the patient’s bloodstream. As an added bonus, once everything is complete, there are no bio-hazardous used needles to dispose of. Now, bioengineers from Massachusetts’ Tufts University have developed what they claim is an even better type of microneedle, which is made from silk.  Read More
