As virus spikes, Europe runs low on ICU beds, hospital staff

In Italy lines of ambulances park outside hospitals awaiting beds, and in France the government coronavirus tracking app prominently displays the intensive care capacity taken up by COVID-19 patients: 92.5% and rising. In the ICU in Barcelona, there is no end in sight for the doctors and nurses who endured this once already.

Measures to reduce the spread of COVID-19 through non-pharmaceutical interventions (NPIs) such as mask wearing and social distancing are a key tool in combatting the impact of the ongoing coronavirus pandemic. These actions also have greatly reduced incidence of many other diseases, including influenza and respiratory syncytial virus (RSV).

Researchers isolate and decode brain signal patterns for specific behaviors

At any given moment in time, our brain is involved in various activities. For example, when typing on a keyboard, our brain not only dictates our finger movements but also how thirsty we feel at that time. As a result, brain signals contain dynamic neural patterns that reflect a combination of these activities simultaneously. A standing challenge has been isolating those patterns in brain signals that relate to a specific behavior, such as finger movements. Further, developing brain-machine interfaces (BMIs) that help people with neurological and mental disorders requires the translation of brain signals into a specific behavior, a problem called decoding. This decoding also depends on our ability to isolate neural patterns related to specific behaviors. These neural patterns can be masked by patterns related to other activities and can be missed by standard algorithms.
