Smart home dashboard to better visualize energy usage

Duke’s Smart Home. Credit: Duke University Duke’s Smart Home generates a lot of data about its energy usage, but no one understands what it means—yet. To make sense of it all, an interdisciplinary team of students is developing a visualization dashboard that will convey consumption data in an easily comprehendible manner. “We want to make the Smart Home more integrated with the technology around it,” said Harvey Shi, a senior double majoring in biomedical engineering and computer science, and president…

Tai Chi offers a low-cost, easily accessible alternative to pulmonary rehabilitation, study finds — ScienceDaily

Finding ways to help patients with COPD improve their functional status is an area of interest for pulmonary healthcare providers. Currently, pulmonary rehabilitation (PR) is used where available to improve exercise capacity and quality of life, but the treatment requires access to trained staff and specialized facilities. A new study in the journal CHEST® looked at Tai Chi as a lower cost, more easily accessed treatment option. Investigators found that this slow, methodical form of exercise is equivalent to PR…

Probing the complex nature of concussion — ScienceDaily

It seems simple enough: Taking a hard hit to the head can give you a concussion. But, Stanford researchers report March 30 in Physical Review Letters, in most cases, the connection is anything but simple. Combining data recorded from football players with computer simulations of the brain, a team working with David Camarillo, an assistant professor of bioengineering, found that concussions and other mild traumatic brain injuries seem to arise when an area deep inside the brain shakes more rapidly…

A next-generation non-hormonal contraceptive for women is being developed in Sweden — ScienceDaily

A hormone-free women’s contraceptive with no side effects is one promising use for a new technique developed by researchers in Sweden to tighten up the mucous membrane – the body’s first line of defense in protecting its inner lining. The approach consists of cross-linking the mucus gel with chitosan, a type of polysaccharide derived from chitin, the substance that develops in the hard outer shells of crustaceans such as shrimp and crayfish. The material tightens the mucin polymer mesh barrier which…

Prosthetic memory system successful in humans — ScienceDaily

Scientists at Wake Forest Baptist Medical Center and the University of Southern California (USC) have demonstrated the successful implementation of a prosthetic system that uses a person’s own memory patterns to facilitate the brain’s ability to encode and recall memory. In the pilot study, published in today’s Journal of Neural Engineering, participants’ short-term memory performance showed a 35 to 37 percent improvement over baseline measurements. “This is the first time scientists have been able to identify a patient’s own brain…

Tattoo electrodes from an ink-jet printer for long-term medical diagnostics

Researchers at TU Graz present tattoo electrodes from the printer, which are particularly attractive for long-term medical diagnostics. Credit: Lunghammer – TU Graz Electrodes for longterm monitoring of electrical impulses of heart or muscles in the form of temporary tattoos produced using an ink-jet printer. An international research group involving TU Graz, Austria, presents this novel method in Advanced Science. In the case of diagnostic methods such as electrocardiogram (ECG) and electromyography (EMG), gel electrodes are the preferred method of…

BIRDS Model uses just two inputs to predict terrestrial locomotion in extinct avian and non-avian dinosaurs — ScienceDaily

A new model based on ground-running birds could predict locomotion of bipedal dinosaurs based on their speed and body size, according to a study published February 21, 2018 in the open-access journal PLOS ONE by Peter Bishop from the Queensland Museum, Australia and colleagues. Previous research has investigated the biomechanics of ground-dwelling birds to better understand the how bipedal non-avian dinosaurs moved, but it has not previously been possible to empirically predict the locomotive forces that extinct dinosaurs experienced, especially…

Stretchable electronics a ‘game changer’ for stroke recovery treatment

Credit: Northwestern University A groundbreaking new wearable designed to be worn on the throat could be a game-changer in the field of stroke rehabilitation. Developed in the lab of Northwestern University engineering professor John A. Rogers, in partnership with Shirley Ryan AbilityLab, the sensor is the latest in Rogers’ growing portfolio of stretchable electronics that are precise enough for use in advanced medical care and portable enough to be worn outside the hospital, even during extreme exercise. Rogers will…
