Live birth rates and perinatal outcomes when all embryos are frozen compared with conventional fresh and frozen embryo transfer: a cohort study of 337,148 in vitro fertilisation cycles (2019)
Journal Article

BACKGROUND: It is not known whether segmentation of an in vitro fertilisation (IVF) cycle, with freezing of all embryos prior to transfer, increases the chance of a live birth after all embryos are transferred. METHODS: In a prospective study of UK H...

Adversity exposure during sensitive periods predicts accelerated epigenetic aging in children (2019)
Journal Article

Objectives: Exposure to adversity has been linked to accelerated biological aging, which in turn has been shown to predict numerous physical and mental health problems. In recent years, measures of DNA methylation-based epigenetic age––known as “epig... Read More about Adversity exposure during sensitive periods predicts accelerated epigenetic aging in children.

Preliminary testing: The devil of statistics? (2019)
Journal Article

In quantitative research, the selection of the most appropriate statistical test for the comparison of two-independent samples can be problematic. There is a lack of consensus in the Statistics community regarding the appropriate approach; particular... Read More about Preliminary testing: The devil of statistics?.

Parametric and non-parametric tests for the comparison of two samples which both include paired and unpaired observations (2019)
Journal Article

Samples that include both independent and paired observations cause a dilemma for researchers that covers the full breadth of empirical research. Parametric approaches for the comparison of two samples using all available observations are considered,... Read More about Parametric and non-parametric tests for the comparison of two samples which both include paired and unpaired observations.

Young carers in England: Findings from the 2018 BBC survey on the prevalence and nature of caring among young people (2019)
Journal Article

© 2019 John Wiley & Sons Ltd Background: Many young people are involved in caring for parents, siblings, or other relatives who have an illness or disability. The aim of this study was to estimate the prevalence of caring by young people in England...

Digging the optimum pit: Antlions, spirals and spontaneous stratification (2019)
Journal Article

Most animal traps are constructed from self-secreted silk, so antlions are rare among trap builders because they use only materials found in the environment. We show how antlions exploit the properties of the substrate to produce very effective struc... Read More about Digging the optimum pit: Antlions, spirals and spontaneous stratification.

Social flocculation in plant–animal worms (2019)
Journal Article

Individual animals can often move more safely or more efficiently as members of a group. This can be as simple as safety in numbers or as sophisticated as aerodynamic or hydrodynamic cooperation. Here, we show that individual plant–animal worms (Syms... Read More about Social flocculation in plant–animal worms.

Sensitive periods for the effect of childhood adversity on DNA methylation: Results from a prospective, longitudinal study (2019)
Journal Article

Background: Exposure to "early life" adversity is known to predict DNA methylation (DNAm) patterns that may be related to psychiatric risk. However, few studies have investigated whether adversity has time-dependent effects based on the age at exposu...
