With the development of an adaptive, multi-view light sheet microscope and a suite of computational tools, researchers have captured the first view of early organ development inside the mouse embryo.
For all the good they do, eye drops and ointments have one major drawback: It's hard to tell how much of the medication is actually getting to the eye. Now in a study appearing in ACS Applied Materials & Interfaces, scientists report that they have developed a contact lens that changes color as drugs are released. This visual indicator could help eye doctors and patients readily determine whether these medications are where they should be.
For those living with diabetes, monitoring blood glucose accurately is necessary to prevent diabetes-related complications. Researchers from the University of Missouri School of Medicine and the Massachusetts Institute of Technology recently evaluated the accuracy of an MIT-developed technology to monitor blood glucose levels without needles or a finger prick. Early results show that the noninvasive technology measures blood glucose levels as effectively as a finger prick test -- without drawing blood.
University of Utah biomedical engineering assistant professor Robby Bowles and his team have developed a method to 3D print cells to produce human tissue such as ligaments and tendons to greatly improve a patient's recovery. A person with a badly damaged ligament, tendon, or ruptured disc could simply have new replacement tissue printed and ultimately implanted in the damaged area.
A newly-developed molecule is easy to make, simple to work with and may potentially be used for the development of targeted medications and high-density memory devices with the volume of a speck of a dust.
UW engineers developed a new machine-learning system that can help anesthesiologists predict the likelihood that a patient will experience low blood oxygen levels during surgery. This condition, called hypoxemia, can lead to serious consequences, such as infections and abnormal heart behavior. The team's system also gives real-world explanations behind its predictions. The researchers estimate that it could improve the ability of anesthesiologists to prevent 2.4 million more hypoxemia cases in the United States every year.
In an advance that could help scientists develop and test new drugs for amyotrophic lateral sclerosis (ALS), MIT engineers have developed the first 3-D human tissue model of the interface between motor neurons and muscle fibers, known as the neuromuscular junction.
Catalytic research led by University of Oklahoma researcher Steven Crossley has developed a new and more definitive way to determine the active site in a complex catalyst. His team's research was recently published in Nature Communications.
UC Berkeley and Berkeley Lab scientists have placed light-absorbing gold nanoclusters inside a bacterium, creating a biohybrid system that produces a higher yield of chemical products, such as biofuels, than previously demonstrated. The biohybrid captures sunlight and carbon dioxide to make chemicals useful not only on Earth but also in the exotic environment of space.
NJIT researchers have detailed the discovery of the first bacterium known capable of simultaneously degrading the pair of chemical contaminants -- 1,4-Dioxane and 1,1-DCE.
