The human brain can learn through experience to filter out disturbing and distracting stimuli -- such as a glaring roadside billboard or a flashing banner on the internet. Scientists have used electroencephalography (EEG) to show that early visual processing in humans changes with repeated exposure.

Ambisonic rendering is a way to simulate the precise locations of sounds in 3D, and an ambisonics algorithm has allowed researchers to create rich virtual 'soundscapes.'Researchers decided to test the limits of ambisonic sound reproduction through their 'AudioDome' loudspeaker array. Humans' spatial acuity is high in front of our faces but decreases around the sides of our head, and the researchers' experiments obtained very similar results from listeners in the AudioDome, proving that the loudspeaker array can reproduce sound locations at a spatial scale beyond the human limits of perception.

An international team of researchers has discovered a natural mechanism that protects the heart from heart failure with preserved ejection fraction (HFpEF), a serious condition in need of effective treatment. The team reports that when the cardioprotective mechanism fails, it promotes the development of HFpEF. Importantly, restoring the mechanism prevents the progression of the condition. The findings provide a promising therapeutic target to prevent and treat this life-threatening disease.
