Article Synopsis
  • - Infants exhibit varying levels of eye movement control, which may be related to autism risks; a study involving 450 twins assessed this using an eye-tracking task.
  • - Findings indicated that shorter eye movement latency in certain task conditions correlates with higher levels of autistic traits reported by parents when the children reached 2 years old.
  • - The results suggest that a significant portion of differences in eye movement latency can be attributed to a heritable factor, with distinct genetic influences at play for visual attention versus basic visual processing abilities.

This longitudinal study explored the impact of COVID-19 on individuals in romantic relationships. The sample spans three waves: first confinement (n = 52), deconfinement (n = 49), and second confinement (n = 26). The study tested sociodemographic factors, psychological adjustment (anxiety, depression, stress, well-being), COVID-19 threat perception, dyadic coping, and relationship quality.

The red seaweed Asparagopsis taxiformis has a potent antimethanogenic effect, which has been proven both in vitro and in vivo. Vegetable oil immersions of this seaweed (hereafter Bromoil) help stabilise the bromoform (CHBr) responsible for its antimethanogenic effect. We evaluate the effects of increasing the levels of CHBr in lamb diets on growth performance, methane (CH) production, animal health and meat quality.

Efficiently processing information from faces in infancy is foundational for nonverbal communication. We studied individual differences in 5-month-old infants' (N = 517) sustained attention to faces and preference for emotional faces. We assessed the contribution of genetic and environmental influences to individual differences in these gaze behaviors, and the association between these traits and other concurrent and later phenotypes.
