Sensor is poised to improve landmine detection and non-destructive testing — ScienceDaily

Detecting landmines can be a challenging and slow process. Detecting them from a moving vehicle would make the process more speedy, but at the expense of accuracy. At the Optical Society’s (OSA) Laser Congress, held 29 September — 3 October 2019 in Vienna, Austria, researchers from the University of Mississippi, U.S.A., will report a new laser-based sensor that effectively detects buried objects even while the detector is in motion. This new device offers a significant improvement over existing technologies, which…

Cannabis may hold promise to treat PTSD but evidence lags behind use — ScienceDaily

As growing numbers of people are using cannabis to treat post-traumatic stress disorder (PTSD), a new UCL study reports that prescriptions are not backed up by adequate evidence. The systematic review, published in the Journal of Dual Diagnosis, finds that the active components of cannabis, called cannabinoids, may hold promise as a treatment for PTSD, particularly for reducing nightmares and helping people sleep, but more research is needed to determine whether these drugs should be used in routine clinical practice.…

Scientists propose network of imaging centers to drive innovation in biological research — ScienceDaily

When sparks fly to innovate new technologies for imaging life at the microscopic scale, often diverse researchers are nudging each other with a kind of collegial one-upmanship. “Look at the resolution we obtain with this microscope I’ve designed,” the physicist says. “Great,” the biologist replies, “but my research organism moves fast. Can you boost the system’s speed?” “You’ll have terabytes of raw data coming off that microscope system,” says the computational scientist. “We’ll build in algorithms to manage the data…

How stress can curb the desire to eat in an animal model — ScienceDaily

Eating disorder researchers at The University of Texas Health Science Center at Houston (UTHealth) have discovered a neurocircuit in mice that, when activated, increased their stress levels while decreasing their desire to eat. Findings appear in Nature Communications. The scientists believe their research could aid efforts to develop treatments for a serious eating disorder called anorexia nervosa, which has the highest mortality rate of any mental disorder, according to the National Institute of Mental Health. People with anorexia nervosa avoid…

Finding could lead to better clinical disease monitoring — ScienceDaily

University of Houston researcher Chandra Mohan is reporting in Arthritis Research and Therapy that clotting proteins, both those that promote blood clots (pro-thrombotic) and those that work to dissipate them (thrombolytic), are elevated in the urine of patients who suffer from lupus nephritis (LN). “Among the proteins examined, urine plasmin emerged as the strongest independent predictor of kidney function and renal disease status,” reports Mohan, Hugh Roy and Lillie Cranz Cullen Endowed Professor of biomedical engineering. “Urine biomarkers represent promising…

MU Biomedical, Biological & Chemical Engineering senior Zachary Valleroy — who has a double major in physics — maximized his engineering and leadership skills this summer, landing an internship with Textron Aviation in Wichita, Kan. Learn a little more about his internship in his own words. Valleroy: This summer at Textron Aviation, I had the opportunity to work in a cross-functional team to perform control…

Mizzou Engineering’s Kannan earns major award from UM System

Raghuraman Kannan recently earned the UM System President’s Award for Economic Development. Recently, the UM System announced the winners of its 2019 President’s Awards, which are given by President Mun Choi in recognition of faculty who have done exceptional work to advance the mission of the System. Mizzou Associate Professor of Biomedical, Biological & Chemical Engineering Raghuraman Kannan was one of 12 awardees, earning the President’s Award for Economic Development. Here’s what the UM System had to say about his…

Take a bath 90 minutes before bedtime to get better sleep — ScienceDaily

Biomedical engineers at The University of Texas at Austin may have found a way for people to get better shuteye. Systematic review protocols — a method used to search for and analyze relevant data — allowed researchers to analyze thousands of studies linking water-based passive body heating, or bathing and showering with warm/hot water, with improved sleep quality. Researchers in the Cockrell School of Engineering found that bathing 1-2 hours before bedtime in water of about 104-109 degrees Fahrenheit can…

Biologist leads pioneering study on stress — ScienceDaily

A biologist at Louisiana State University conducted a pioneering research study that could help us to better understand the role of dopamine in stress resilience in humans through analyzing wild songbirds. This study could lead to increased prevention and treatment of stress-related disorders. Dopamine is a chemical in the brain that is important for learning and memory. Department of Biological Sciences Assistant Professor Christine Lattin, and colleagues conducted this study of wild songbirds showing that dopamine is important in responding…
