Researchers at MIT have developed a sensor system that can provide data on how well a face mask fits to a wearer’s face. The protection offered by a mask is largely dependent on how well it fits the face, but at present most face masks are one-size-fits-all and most wearers are largely unaware if their mask is providing maximal protection. This latest technology is an adhesive polymer frame containing a range of sensors.

Researchers at Imperial College London in the UK have developed a flexible catheter system that is designed to enable access and treatment of the deep areas of the brain. At present, catheters intended for such applications can suffer from rigidity, making it difficult to access the brain safely and effectively. This latest technology includes a robotic arm that steers the catheter through the brain.

A team of scientists at Penn State has bioprinted breast tumor mimics with significant complexity, including a form of vascularization and the ability to precisely place cells in certain locations within the construct. The scientists used a technique called aspiration-assisted bioprinting to achieve this.

Scientists at Oregon State University have developed a new treatment for COVID-19. The technology is based on mRNA, which has also been put to good use in COVID-19 vaccines. However, in this instance, the delivered mRNA encodes for human angiotensin-converting enzyme 2 (hACE2), which is the binding site for SARS-CoV-2 on airway cells.

Researchers at Osaka University in Japan engineered a wearable electroencephalography (EEG) device that can measure brain activity, potentially letting clinicians monitor conditions such as depression or dementia. At present, assessing brain activity requires a trip to a facility with bulky and expensive equipment, making long-term monitoring difficult. This latest technology aims to allow for at-home measurements of brain activity.

Scientists at Cortical Labs in Melbourne, Australia, along with international collaborators, have developed “DishBrain”, which is essentially a collection of neurons in a dish that have demonstrated learning and, incredibly, can play the classic computer game Pong.
