Multifunctional e-glasses monitor health, protect eyes, control video game

Smart e-glasses can wirelessly monitor EEG and EOG signals, UV intensity, and body movements, while also acting as sunglasses and a human-machine interface. Credit: Adapted from ACS Applied Materials & Interfaces 2020, DOI: 10.1021/acsami.0c03110 Fitness tracker bracelets and watches provide useful information, such as step count and heart rate, but they usually can’t provide more detailed data about the wearer’s health. Now, researchers reporting in ACS Applied Materials & Interfaces have developed smart electronic glasses (e-glasses) that not only monitor…

Multifunctional e-glasses monitor health, protect eyes, control video games — ScienceDaily

Fitness tracker bracelets and watches provide useful information, such as step count and heart rate, but they usually can’t provide more detailed data about the wearer’s health. Now, researchers reporting in ACS Applied Materials & Interfaces have developed smart electronic glasses (e-glasses) that not only monitor a person’s brain waves and body movements, but also can function as sunglasses and allow users to control a video game with eye motions. Devices that measure electrical signals from the brain (electroencephalogram; EEG)…

Ancient ocean oxygen levels associated with changing atmospheric carbon dioxide — ScienceDaily

Why do carbon dioxide levels in the atmosphere wax and wane in conjunction with the warm and cold periods of Earth’s past? Scientists have been trying to answer this question for many years, and thanks to chemical clues left in sediment cores extracted from deep in the ocean floor, they are starting to put together the pieces of that puzzle. Recent research suggests that there was enhanced storage of respired carbon in the deep ocean when levels of atmospheric carbon…

Protein shapes matter in Alzheimer’s research — ScienceDaily

Sometimes proteins misfold. When that happens in the human brain, the pileup of misfolded proteins can lead to neurodegenerative diseases like Alzheimer’s, Parkinson’s and ALS. Proteins do not misbehave and misfold out of the blue. There is a delicate ecosystem of biochemical interactions and environments that usually let them twist, unfold, refold and do their jobs as they’re meant to. However, as researchers from Michigan Technological University explore in an article published in ACS Chemical Neuroscience, even a small change…

Switching Modalities Mid-Term to High-Quality Online Leads to Similar Learning Outcomes

Heather Hunt is an associate professor in the Department of Biomedical, Biological and Chemical Engineering and a Faculty Fellow for Strategic Initiatives in the Office of eLearning at the University of Missouri. Students who switch from face-to-face teaching to high-quality online even within a semester show similar learning outcomes – yet overall prefer the online setting, a new study has found. This spring, when the COVID-19 outbreak forced the University of Missouri and other institutions of higher education to move…

Aiways Develops Safer EV Battery, Announces Mobile Charging Robot Patents

Chinese EV manufacturer Aiways revealed further details of its 63-kWh battery pack, a multilayered “sandwich” battery pack that allows for a greater specific capacity of cells per kg while still ensuring adequate cooling and protection from damage. The company also announced it has been granted seven patents across Europe and China that cover its autonomous mobile charging robot CARL. The battery pack consists of a system of rechargeable cells comprised of cooling and insulating boards (Fig. 1). The battery pack’s…

More Power to You: The Auto’s Electrical Overhaul

Download this article in PDF format. Automotive electrical systems are undergoing a major overhaul as a result of evolving vehicle powertrains and related systems. Three major considerations are the new 12-V plus 48-V electrical systems, complex multiple charging systems in electric vehicles (EVs) and plug-in hybrid EVs (PHEVs), and the growing demand for better sensors to manage the increasingly complex powertrains. Texas Instruments is addressing all of these requirements.  Sponsored Resources:  12/48-V Systems Auto manufacturers are beginning to roll out…

NIST ‘high priority’ list identifies critical need for improved plumbing

Legionella bacteria prosper in hot water lines and can infect people who inhale contaminated droplets during steamy showers. Credit: nikkytok/Shutterstock We don’t use water like we used to. In recent decades, concerns about cost, water shortages and environmental impacts together with changes in plumbing design have driven down water usage per person. But because plumbing codes have not kept pace with the shifting demand, water quality may be suffering. The current codes for plumbing systems within buildings are based in part…
