A Melbourne-led team has for the first time shown that 800,000 brain cells living in a dish can perform goal-directed tasks - in this case the simple tennis-like computer game, Pong. Now they are going to find out what happens when their DishBrain is affected by medicines and alcohol.

Researchers have developed an electroencefalography electrode that patients wear on their head to monitor brain activity. The EEG electrodes system could act as a brain-computer interface, which can be controlled by brain signals to help repair damage to the brain caused by strokes and other disorders.

The latest wearable sensors report from IDTechEx, "Wearable Sensors 2023-2033", breaks down the complex landscape of sensor types, biometrics, and form factors. IDTechEx highlights the key opportunities and challenges for each sensor type to achieve commercial success across the next ten years.

Chemists are now a step closer to their goal of developing a handheld tool similar to an alcohol Breathalyzer that can detect THC on a person's breath after they've smoked marijuana.
