How the 'noise' in our brain influences our behavior
The brain's neural activity is irregular, changing from one moment to the next. To date, this apparent ''noise'' has been thought to be due to random natural variations or measurement error.

Healthy oceans need healthy soundscapes
Rain falls lightly on the ocean's surface. Marine mammals chirp and squeal as they swim along. The pounding of surf along a distant shoreline heaves and thumps with metronomic regularity. These are the sounds that most of us associate with the marine environment. But the soundtrack of the healthy ocean no longer reflects the acoustic environment of today's ocean, plagued with human-created noise. (2021-02-05)

Human-generated noise pollution dominates the ocean's soundscape
The soundscapes of the Anthropocene ocean are fundamentally different from those of pre-industrial times, becoming more and more a raucous cacophony as the noise from human activity has grown louder and more prevalent. (2021-02-04)

Traffic noise makes mating crickets less picky
New research has found that the mating behaviour of crickets is significantly affected by traffic noise and other man-made sounds. When man-made noise pollution was present, the females didn't take into account the courtship song of the male crickets during mating. As the courtship song is energetically costly and provides crucial information about the health of the male, this could affect long-term population viability as females could choose less suitable mates.

Precision measurements of intracluster light suggest possible link to dark matter
Faint light from rogue stars not bound to galaxies has been something of a mystery to scientists. The dimness of this intracluster light makes it difficult to measure, and no one knows how much there is. Scientists on the Dark Energy Survey, led by Fermilab, have made the most radially extended measurement of this light ever, and they've found that its distribution might point to the distribution of dark matter.

The phantom chorus: birdsong boosts human well-being in protected areas
Although many studies have found that humans benefit from spending time in nature, few studies have explored why. Researchers hid speakers that played recorded songs from a diverse group of birds on two sections of trails in Colorado. Hikers who heard the bird songs reported a greater sense of well-being than those who didn't. The survey results showed that both the sounds themselves and people's perception of biodiversity can increase humans' feelings of well-being. (2020-12-15)
