New study reveals how human astroviruses bind to humans cells and paves the way for new therapies and vaccines Human astroviruses are a leading viral cause of the stomach bug—think vomiting, diarrhea, and fever. It often impacts young children and older adults, leading to vicious cycles of sickness and malnutrition, particularly for those in low and middle income countries. It’s very commonly found in wastewater studies, meaning it’s frequently circulating in communities. As of now, there are no vaccines for…
Due to their stability and resistance to water and grease, PFAS chemicals are used in a wide range industries, but they are harmful to health and the environment. Membranes containing PFAS are used in many semiconductor manufacturing processes, for example. Researchers from the Fraunhofer IAP have now developed a sustainable alternative in the form of an innovative, PFAS-free membrane. The chemically stable, highly permeable polymer membrane has a pore diameter of approx. seven nanometers and enables filtration of the smallest…
Animal testing has long been a fixture of medical and pharmaceutical research, but alternative methods are growing more and more important. Innovative methods allow for research aimed directly at humans — without using animal testing as an intermediate step. TigerShark Science, a planned Fraunhofer start-up and spin-off of the Fraunhofer Translational Center for Regenerative Therapies TLC-RT at the Fraunhofer Institute for Silicate Research ISC, is taking this kind of approach. TigerShark Science hopes to use skin models grown from human…
MRI scans are commonly used to diagnose a variety of conditions, anything from liver disease to brain tumors. But, as anyone who has been through one knows, patients must remain completely still to avoid blurring the images and requiring a new scan. A prototype device described in ACS Sensors could change that. The self-powered sensor detects movement and shuts down an MRI scan in real time, improving the process for patients and technicians. During an MRI scan, a patient must…
Skin can send certain health-related signals, such as dry skin feeling tighter to indicate the need for moisture. But what if skin could be smarter, capable of monitoring and sharing specific health information, such as the concentration of glucose in sweat or heart rate? That was the question driving a team led by Penn State researchers that recently developed an adhesive sensing device that seamlessly attaches to human skin to detect and monitor the wearer’s health. The details of the…
Vessel-chip technology may offer a future of more personalized pharmaceutical drug testing, leading to our improved ability to combat disease. The pharmaceutical drug development and approval process is a multi-step undertaking that requires a plethora of testing before reaching the market. Even then, humans respond differently to drugs depending on their individual bodies and medical needs. Dr. Abhishek Jain, associate professor in the Department of Biomedical Engineering, and his lab received a grant from Texas A&M Innovation to continue developing an advanced…
MHH study identifies new autoantibodies in cerebrospinal fluid as a possible biomarker for rapidly progressing cerebellitis. Cerebellar ataxia is a neurological disorder of the cerebellum. This important area at the back of the brain acts as a conductor, so to speak, coordinating our movements and keeping us in balance. This ability is impaired in cerebellar ataxia. Affected people can have difficulties walking, speaking and grasping or even with controlled eye movements. In some cases, the damage begins gradually and develops…
Dr. Melissa Grunlan is developing synthetic plugs for patients suffering from chronic knee pain or disabilities that would avoid total knee replacements. Osteochondral defects (OCDs) can cause damage to cartilage and underlying bone, leading to chronic pain and loss of joint function. Depending on the extent of damage, individuals must undergo surgical treatment, the most extensive being total knee replacement, which over 800,000 Americans undergo each year. Dr. Melissa Grunlan, professor in the Department of Biomedical Engineering at Texas A&M…

Climate change, and specifically rising temperatures, will place a great strain on plant growth and will almost certainly…
Improves outlook for lymphoma patients… A team of cancer researchers, led by the University of Houston, has discovered a new subset of T cells that may improve the outcome for patients treated with T-cell therapies. T cell-based immunotherapy has tremendous value to fight, and often eliminate, cancer. The strategy activates a patient’s immune system and engineers a patient’s own T cells to recognize, attack and kill cancer cells. In this way, the body’s own T cells become living drugs. While…
