Electrochemical Device Detects SARS‑CoV‑2 Spike Protein in 1 Second

Researchers at the University of Florida and the National Chiao Tung University in Taiwan have developed a microfluidic device that can detect the SARS‑CoV‑2 spike protein in a saliva sample within one second. The electrochemical device employs antibodies against the spike protein to detect the virus, and could allow for ultra-rapid COVID-19 testing.    Testing… Read More »

Brain Stimulation Lets User Feel Robotic Arm

Researchers at the University of Pittsburgh have demonstrated that providing direct sensory feedback into the brain dramatically enhanced an impaired patient’s control of a robotic arm. The arm was operated through a brain-computer interface, but the system also included brain implants in an area of the brain responsible for sensory feedback. When the patient completed… Read More »

Self-stigma, especially around substance use, impedes HIV self-care among gay and bisexual men living with HIV who use drugs

A qualitative study sought to understand how internalised stigma affects HIV self-care among gay and bisexual men living with HIV who use substances. Men in this cohort experienced self-stigma stemming from multiple intersecting identities, including their HIV status, sexual orientation, race, effeminateness, poverty, and housing instability. Self-stigma around drug use was reported as the most… Read More »
