In JASA Express Letters, researchers evaluate the relationships between sound quality, speech recognition, and quality-of-life outcomes for cochlear implant (CI) users. They found CI sound quality leads to a 32% variance in users’ quality of life — in contrast, speech recognition has virtually no predictive power over quality of life. In their study, speech recognition only correlated with sound quality under noisy conditions, suggesting it is particularly relevant in situations with background noise and different sound sources — in other words, the real world.

MIT engineers designed a control mechanism, known as DIAL, that allows them to establish a desired protein level, or set point, for any synthetic gene circuit.

Land cover is constantly changing due to climate pressures and human activities, yet traditional satellite monitoring often misses rapid events.
