When a patient seriously injures their foot or ankle, their doctor often gives them a surgical boot to help them recover, and specific instructions on how much activity and bodyweight the limb should bear per day during recovery. But at follow-up visits, the doctor has to rely on the patient’s self-reporting to determine whether or not the patient followed instructions. It’s a tricky process. The patient may have followed the plan, or not followed the plan, or thought they were following the plan when in fact they weren’t. To reduce guesswork in recovery, alexandra hammerberg and patricia kramer from the UW department of anthropology have developed the data-assisted surgical (DAS) recovery boot, a pressure-sensitive device that can collect real-time data on a patient activity and signal when they are exceeding recommended activity limits.

It can also share that activity with the patient’s doctor, enabling them adapt the treatment plan as necessary so the patient can heal as quickly as possible.

According to the institute for health metrics and evaluation, diarrheal diseases are the fifth-leading cause of death for children under the age of five. Low-resource settings are overwhelmingly burdened with pediatric diarrheal diseases, and when death occurs in these situations, it is often because the initial status of dehydration is underestimated, or because ongoing fluid loss is not monitored or taken into consideration. Now, a team of bioengineering students led by vidhi singh will develop an inexpensive dehydration monitor that does not require fluid samples. American college student north korea this type of monitoring is a departure from commonly-used methods, which rely on qualitative hydration assessments that often don’t result in prompt and appropriate treatment. This device can detect dehydration levels based on the propagation of ultrasonic shear-waves through subcutaneous tissue, ultimately providing a rapid dehydration measurement in the field, which will let clinicians decide the optimal course of treatment, reducing waste of limited medical supplies and improving patient outcomes.

Space-resource utilization is essential to the long-term sustainability of the human species, both here on earth and on future martian homes. While asteroids hold the key to many valuable resources, such as gold, aluminum, or titanium, visiting known asteroids requires prohibitively big efforts, turning missions into high-risk, low-payoff ventures. Finding asteroids closer to earth is therefore essential. Special types of asteroids called the trojans are located at a gravitational equilibrium between two larger bodies. While over six thousand such asteroids have been discovered in our solar system—the most famous being the trojan asteroids of jupiter—there are only two known sun-earth trojans. Astronomers, however, predict there should be many more. Now, paul sturmer and jeff chrisope from the UW have a plan to find those missing asteroids, with the sun-earth trojan asteroid mapper, or SETAM. The SETAM cubesat satellite will survey the sun-earth L5 trojan region. Discovering new earth trojan asteroids here will be invaluable, as these asteroids will have a considerably lower energy requirement for space-resource rendezvous.

No one likes to learn from their dentist that they have a cavity that needs filling. According to NIDCR (national institute of dental and croniafacial research), more than 90% of us suffer from some form of tooth decay. Current fillings and dental inlays are made of ceramic glasses, resin-based composites, or mercury-containing amalgam fillers. These fillers can be toxic or have durability issues. Some even leach chemicals into the oral cavity. Anerican university now, a team of engineers and dental clinicians led by hanson fong from the UW department of materials science & engineering have engineered an innovative material to address these issues. Combining their proprietary mineralization directing peptide, derived from natural enamel protein, a mineralizing hydrogel is developed that can be 3D printed at a high resolution that replicates the chemistry, form, and function of the natural dental tissue with good integration with the remaining tooth. This novel method will provide dentists with a practical and healthy treatment to restore patients’ dental cavities to their natural state instead of plugging them with foreign materials with unforeseen consequences – as is the case in current practice.

About every three seconds, someone suffering from osteoporosis breaks a bone. Even so, most cases of osteoporosis still go undiagnosed, since the two current methods for detecting the disease are expensive and unwieldly. But what if people could screen themselves? What if they could do it inexpensively, and at home, using just their smartphone? That is what a team of engineers and computer scientists led by josh fromm hopes to enable. They are developing osteoapp, an app for smartphones that tests bone density and tells the user whether they are at a significant risk for bone disease. Just like any other solid, be it a guitar string or a rock, bones have a natural frequency at which they resonate. OsteoApp uses a vibration technique that emits a pulse from the smartphone, causing a bone to "ring" at its resonate frequency—a function of the bone’s stiffness and density. The smartphone’s microphone then listens to the ringing bone. From this, osteoapp can estimate bone density and recommend whether the user contact a physician—staving off pain and suffering for middle-aged or older women and men all over the world.

The world’s cultivated soils have lost 50–70% of their original carbon due to agricultural practices. According to the united nations, this loss could result in a 17% decline in food production by 2100. To put carbon back into soils, a team led by soil scientist tom deluca is touting the benefits of charcoal. Their work has shown that adding charcoal increases the amount of carbon in topsoil by 30%, as well as the nutrient content of food grown in that soil. Top universities london but for all its benefits, charcoal has struggled in the market due to a lack of, well, marketing. Many farmers just don’t know how much charcoal can help them. Adding to the problem is that there isn’t a reliable, cheap way to make charcoal. But deluca’s team says there is: simply use the woody waste that comes from forest restoration projects throughout the region. To develop the supply side of the charcoal market, deluca’s team is working to integrate charcoal production into forest restoration projects, which will not only decrease fire danger, but also connect sound forest management with food security.

More than 1 in 40 people suffer from body focused repetitive behaviors (bfrbs), such as trichotillomania (compulsive hair pulling) and excoriation disorder (compulsive skin picking). These types of disorders are hard to treat–the associated behaviors are often done unconsciously–so therapists have found the best approach is often to teach patients to become aware of their actions. But how can patients be reminded of these behaviors when they are on their own? Matthew and joseph toles started slightly robot and developed a smartwatch app and standalone bracelet that uses an accelerometer to monitor the motion and position of users’ hands, vibrating to let them know whenever they are pulling or picking. Perhaps even more useful, the app tracks the frequency of compulsive behavior over time, meaning that for the first time, users, patients, and researchers can receive accurate, quantitative feedback on their progress. Given the willpower and concentration necessary to overcome body focused repetitive behaviors, even a small amount of positive, real-time feedback can go a long way.

The earth’s climate is undergoing massive shifts, and the impacts of those changes are already profound. But while current climate models are good at predicting the extent to which projected changes will vary all over the planet, they are less good at predicting what exactly those changes will look like at local or even regional scales. But that’s precisely the information that is crucial for government officials who want to bolster existing infrastructure—e.G., dams, roads, and reservoirs—so it can withstand the promised stresses of future climate scenarios. Now, a team of climatologists led by cliff mass is building a sophisticated climate prediction system that will give those planners a boost. The model they have developed, which can be applied anywhere in the world, will take global climate simulations and downscale them using high-resolution regional models. The result will be a state-of-the science probabilistic prediction of what sort of changes people can expect right where they live.
