Apparent Parity Violation in the Observed Galaxy Trispectrum.

Phys Rev Lett

September 2024

Department of Physics and Astronomy, University of the Western Cape, Cape Town 7535, South Africa.

Recent measurements of the four-point correlation function in large-scale galaxy surveys have found apparent evidence of parity violation in the distribution of galaxies. This cannot happen via dynamical gravitational effects in general relativity. If such a violation arose from physics in the early Universe it could indicate important new physics beyond the standard model, and would be at odds with most models of inflation.

Background: Controversy regarding the neurodiversity movement (NDM), the social and medical models of disability, autism intervention goals, and causal attributions of disability contributes to divides in the autistic and autism communities. The present study investigates the views of autistic and non-autistic autistic and autism community members on these topics. We explored whether these views are shaped by having close relationships to autistic people with intellectual disabilities (ID) and nonspeaking autistic (NSA) people.

Background: Older adults are at increased risk of both falls and fall-related injuries. Falls have multiple causes and many interventions exist to try and prevent them, including educational and psychological interventions. Educational interventions aim to increase older people's understanding of what they can do to prevent falls and psychological interventions can aim to improve confidence/motivation to engage in activities that may prevent falls.

Veracity Judgments Based on Complications: A Training Experiment.

Behav Sci (Basel)

September 2024

School of Psychology, Sport and Health Sciences, University of Portsmouth, Portsmouth PO1 2DY, UK.

Research has shown that complications are more common in truth tellers' accounts than in lie tellers' accounts, but there is currently no experiment that has examined the accuracy of observers' veracity judgments when looking at complications. A total of 87 participants were asked to judge 10 transcripts (five truthful and five false) derived from a set of 59 transcripts generated in a previous experiment by Deeb et al. Approximately half of the participants were trained to detect complications (Trained), and the other half did not receive training (Untrained).

Characterization of a cytochrome P450 that catalyzes the O-demethylation of lignin-derived benzoates.

J Biol Chem

November 2024

Department of Microbiology and Immunology, Life Sciences Institute and Bioproducts Institute, The University of British Columbia, Vancouver, Canada. Electronic address:

Cytochromes P450 (P450s) are a superfamily of heme-containing enzymes possessing a broad range of monooxygenase activities. One such activity is O-demethylation, an essential and rate-determining step in emerging strategies to valorize lignin that employ carbon-carbon bond cleavage. We recently identified PbdA, a P450 from Rhodococcus jostii RHA1, and PbdB, its cognate reductase, which catalyze the O-demethylation of para-methoxylated benzoates (p-MBAs) to initiate growth of RHA1 on these compounds.

  • Researchers studied strokes from 1990 to 2021 to understand how many people get them and how they are affected around the world.
  • In 2021, strokes caused about 7.3 million deaths and were a major cause of health problems, especially in specific regions like Southeast Asia and Oceania.
  • There are differences in stroke risks based on where people live and their age, and some areas actually saw more strokes happening since 2015.

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.

Social work assessments underpin support plans for many people living with dementia in their own homes in England, but it is unclear how they acknowledge that dementia places people at greater risk of mouth and dental problems affecting their wellbeing. We explored if and how dental needs are addressed during care assessments and social workers' perceptions of this aspect of personal care. This study analysed (a) semi-structured interviews with 14 social workers providing support to people living with dementia in their own homes, (b) data from 39 care assessments and support plans from two English local authorities.

To reduce breast motion with a bra, we need to understand what drives the motion of the breasts, and what variables change as support increases. Quantifying breast-torso coordination and movement complexity across the gait cycle may offer deeper insights than previously reported discrete time lag. We aimed to compare breast-torso coordination and mutual influence across breast support conditions during running.

Whether it is possible to reappraise parents using non-suggestive questions, and whether this has an impact on emotions and memories, is of great interest in both life and psychotherapy. Past research has shown reappraisals of past situations is associated with changes in memories of emotions. In previous work we showed memories of love could be affected by reappraisals, but did not analyze that dataset on other memories of emotion.
