The inclusion of habits in the stage model of self-regulated behavior change: an investigation of life events and red meat consumption in the UK.

A shift to a diet with low or no red meat is considered necessary to end the environmental and health impacts caused by the current overconsumption of red meat. The self-regulated behavior change stage model (SSBC) proposes that people who intend to change their behavior progress through a series of discrete cognitive stages until, ultimately, they engage in the new behavior. However, what the consequences of habitual behaviors are for the initiation and progression through the stages of change have not yet been fully elucidated or investigated.

Establishment of CRISPR/Cas9-based knock-in in a hemimetabolous insect: targeted gene tagging in the cricket Gryllus bimaculatus.

Studies of traditional model organisms such as the fruit fly Drosophila melanogaster have contributed immensely to our understanding of the genetic basis of developmental processes. However, the generalizability of these findings cannot be confirmed without functional genetic analyses in additional organisms. Direct genome editing using targeted nucleases has the potential to transform hitherto poorly understood organisms into viable laboratory organisms for functional genetic study.

Squeezing the quantum noise of a gravitational-wave detector below the standard quantum limit.

The Heisenberg uncertainty principle dictates that the position and momentum of an object cannot be simultaneously measured with arbitrary precision, giving rise to an apparent limitation known as the standard quantum limit (SQL). Gravitational-wave detectors use photons to continuously measure the positions of freely falling mirrors and so are affected by the SQL. We investigated the performance of the Laser Interferometer Gravitational-Wave Observatory (LIGO) after the experimental realization of frequency-dependent squeezing designed to surpass the SQL.

Gene Protein Sequence Evolution Can Predict the Rapid Divergence of Ovariole Numbers in the Drosophila melanogaster Subgroup.

Ovaries play key roles in fitness and evolution: they are essential female reproductive structures that develop and house the eggs in sexually reproducing animals. In Drosophila, the mature ovary contains multiple tubular egg-producing structures known as ovarioles. Ovarioles arise from somatic cellular structures in the larval ovary called terminal filaments (TFs), formed by TF cells and subsequently enclosed by sheath (SH) cells.

What are the predictors of delayed cerebral ischaemia (DCI) after aneurysmal subarachnoid haemorrhage? An up-to-date systematic review.

Purpose: Delayed Cerebral Ischaemia (DCI) remains an important preventable driver of poor outcome in aneurysmal subarachnoid haemorrhage (aSAH). Our ability to predict DCI is based on historical patient cohorts, which use inconsistent definitions for DCI. In 2010, a definition of DCI was agreed upon and published by a group of aSAH experts.
