More RNA from jumping DNA was not linked to shorter life in flies

Experiments in three fruit fly species challenged the idea that jumping DNA concentrated on the Y chromosome helps explain males’ shorter lives.Experiments in three fruit fly species challenged the idea that jumping DNA concentrated on the Y chromosome helps explain males’ shorter lives.

Frailty changes linked to hearing loss in midlife and later

Adults who became pre-frail or frail had higher hearing-loss risk than those who stayed robust, with hazard ratios of 1.27 and 1.22.Adults who became pre-frail or frail had higher hearing-loss risk than those who stayed robust, with hazard ratios of 1.27 and 1.22.

Gene activity changes linked to dopamine imbalance in mice

Experiments in male and female mice aged 5–7 and 14–16 months linked abnormal gene activity to changes in dopamine-related brain circuits.Experiments in male and female mice aged 5–7 and 14–16 months linked abnormal gene activity to changes in dopamine-related brain circuits.
