He tracked pH levels and concentrations of bacteria, oxygen, lead and sulphate in this new study. (2021-02-08)

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.

NAD+ can restore age-related muscle deterioration
Scientists at EPFL have discovered that Alzheimer's-like protein aggregates underly the muscle deterioration seen in aging. But the aggregates can be reversed by boosting the levels of nicotinamide adenine dinucleotide (NAD+), which turns on the defense systems of mitochondria in cells and restores muscle function.
