NIH-Funded Modern “White Cane” Brings Navigation Assistance To The 21st Century
Equipped with a color 3D camera, an inertial measurement sensor, and its own on-board computer, a newly improved robotic cane could offer blind and visually impaired users a new way to navigate indoors.
When paired with a building’s architectural drawing, the device can accurately guide a user to a desired location with sensory and auditory cues, while simultaneously helping the user avoid obstacles like boxes, furniture, and overhangs. Development of the device was co-funded by the National Institutes of Health’s National Eye Institute (NEI) and the National Institute of Biomedical Imaging and Bioengineering (NIBIB). Details of the updated design were published in the journal IEEE/CAA Journal of Automatica Sinica.
“Many people in the visually impaired community consider the white cane to be their best and most functional navigational tool, despite it being century-old technology,” sai

What You Need To Know About The Delta Variant
For more than 40 years, UCI infectious disease researcher Michael Buchmeier has studied coronaviruses, and he’s one of the leading experts on SARS-CoV-2, the version of the virus causing the COVID-19 pandemic. As a more lethal mutation of the virus, called the delta variant, sparks another wave of cases, he offers his expertise about this threat.
How does the delta variant differ from the original form of the COVID-19 coronavirus?
The form of the original coronavirus is really not clear. If, as we think, SARS-CoV-2 appeared in humans after jumping from an animal host, such as a bat, then the sequence may have already contained mutations in its genome that allowed that species jump. Many of the so-called emerging diseases represent jumps from a zoonotic animal host to humans.
The power of this genetic flexibility is characteristic of RNA viruses. This flexibility results in the produ

NYU Langone Orthopedic Surgeons Presented Latest Clinical Findings & Research at AAOS 2021
Experts from NYU Langone Orthopedics presented their latest clinical findings and research discoveries at the annual American Academy of Orthopaedic Surgeons (AAOS) conference, August 31 to September 2, in San Diego.
Topics presented: when not to operate on spinal deformity in adults; patient satisfaction using telemedicine for arthroscopic surgery follow-up; and representation of women in academic orthopedic leadership.
"The diversity of our research interests, the quality of our clinical teams and the expertise in knowing when or when not to operate are on full display this year," said Joseph Zuckerman, MD, the Walter A. L. Thompson Professor of Orthopedic Surgery, chair of the Department of Orthopedic Surgery at NYU Langone, and former president of AAOS. "We also thank Dr. Joseph Bosco, vice chair for clinical affairs, for completing his AAOS presidency during an exceptionally chall

Driving With Heart Disease: Checking Fitness To Drive
People suffering from various types of cardiovascular disease are subject to a certain accident risk when driving a vehicle on the road. High blood pressure, coronary heart disease and cardiac insufficiency might be grounds for a (temporary) driving ban. Numerous diseases are capable of causing traffic accidents and therefore impact personal and public safety. In a publication, cardiologist Thomas Pezawas from MedUni Vienna has summarised the relevant diseases, thereby providing an overview for those affected and their treating physicians. Palpitations and dizziness can also occur in those recovering from COVID-19.
"Although only between 1 and 5% of sudden cardiac deaths occur while people are driving, even a brief black-out at the wheel can have fatal consequences," explains study author Thomas Pezawas from the Department of Medicine II (Division of Cardiology). "People with heart dis
