A substantial portion of the literature investigating whether playing video games with violent content causes aggressive thoughts, feelings, and behaviors has relied on experimental exposure to video game violence. To date, there is significant evidence suggesting these concepts are positively related, while other experiments demonstrate a null effect. A potential explanation for these contradicting findings is a failure to account for confounding such as video game performance and video game experience.

Article Synopsis
  • Understanding the evolution of genomic variation is essential for creating effective conservation strategies for threatened species, focusing on connectivity, demographic changes, and environmental adaptation.
  • The study analyzed genomic variation in Fraxinus latifolia, a riparian tree facing threats from the invasive emerald ash borer, by sequencing over 1000 individuals from 61 populations.
  • Results showed strong population structure and low genetic diversity, suggesting that this patchy distribution could hinder the species' long-term evolutionary potential, underscoring the importance of conserving genomic diversity for future restoration efforts.

Periprosthetic joint infection (PJI) is a leading cause and major complication of joint replacement failure. As opposed to standard-of-care systemic antibiotic prophylaxis for PJI, we developed and tested titanium femoral intramedullary implants with titania nanotubes (TNTs) coated with the antibiotic gentamicin and slow-release agent chitosan through electrophoretic deposition (EPD) in a mouse model of PJI. We hypothesized that these implants would enable local gentamicin delivery to the implant surface and surgical site, effectively preventing bacterial colonization.

Article Synopsis
  • The study compares the effects of a non-antibiotic treatment (intrauterine dextrose) versus systemic antibiotics (ceftiofur) on the vaginal microbiome of dairy cows with clinical metritis around 7 days post-calving.
  • Results indicated that both treatments resulted in only minor differences in the microbiome, suggesting that dextrose could be a viable alternative to antibiotics.
  • The study found no significant changes in alpha or beta diversity of the microbiome among the two treatments at various time points.

Dynamical symmetries, time-dependent operators that almost commute with the Hamiltonian, extend the role of ordinary symmetries. Motivated by progress in quantum technologies, we illustrate a practical algebraic approach to computing such time-dependent operators. Explicitly we expand them as a linear combination of time-independent operators with time-dependent coefficients.

Article Synopsis
  • Germline genetic testing (GT) is recommended for ovarian cancer (OC) and some endometrial cancer (EC) patients, but participation is low due to various barriers.
  • A quality improvement study at a medical center tracked 116 newly diagnosed OC/EC patients, achieving high GT rates (91% for OC, 75% for EC) and rapid result availability.
  • Identified barriers include missed recommendations, patient overwhelm, financial/privacy concerns, and language issues; the study suggests enhancing GT encouragement throughout treatment and offering multilingual digital consent options.

Potato () is the third most important food crop in the world. Although the potato genome has been fully sequenced, functional genomics research of potato lags relative to other major food crops due primarily to the lack of a model experimental potato line. Here, we present a diploid potato line, 'Jan', which possesses all essential characteristics for facile functional genomics studies.

Aim: Extending faecal immunochemical tests for haemoglobin (FIT) to all primary care patients with symptoms suggestive of colorectal cancer (CRC) could identify people who are likely to benefit from colonoscopy and facilitate earlier treatment. The aim of this work was to investigate the diagnostic accuracy of FIT across different analysers at different thresholds, as a single test or in duplicate (dual FIT).

Method: This systematic review and meta-analysis searched 10 sources (December 2022).

The dry forests of northern Peru are dominated by the legumous tree Neltuma pallida which is adapted to hot arid and semiarid conditions in the tropics. Despite having been successfully introduced in multiple other areas around the world, N. pallida is currently threatened in its native area, where it is invaluable for the dry forest ecosystem and human subsistence.

Background: Peanut allergy is a potentially life-threatening food allergy in children. This study explored whether dupilumab, a human monoclonal immunoglobulin (Ig)G4 antibody that blocks the activity of interleukin (IL)-4/IL-13, improved safety and desensitization to peanut exposure in children with peanut allergy.

Methods: A Phase II, 24-week, multicenter, single-arm, open-label, proof-of-concept study was conducted in the USA and Canada (NCT03793608).

Background: Peanut allergy is a common, life-threatening food allergy in children. We evaluated whether dupilumab, which blocks the activity of interleukin (IL)-4/IL-13, enhances the efficacy of oral immunotherapy (OIT) AR101 in pediatric patients with peanut allergy.

Methods: A Phase II, multicenter, randomized, double-blind study was conducted in the USA (NCT03682770) in pediatric patients (6-≤ 17 years old) with confirmed peanut allergy.

Potato is a key food crop with a complex, polyploid genome. Advancements in sequencing technologies coupled with improvements in genome assembly algorithms have enabled generation of phased, chromosome-scale genome assemblies for cultivated tetraploid potato. The SpudDB database houses potato genome sequence and annotation, with the doubled monoploid DM 1-3 516 R44 (hereafter DM) genome serving as the reference genome and haplotype.

Unlabelled: Social media (SM) is widely used among adolescents, making the relationship between SM and affect in this population important to understand. However, previous research has largely used methods that do not capture the dynamic and variable nature of SM or measure the consistency of effects across global affect and specific emotions. The current study examined the momentary relationship between positive and negative SM experiences and global positive affect (PA) and negative affect (NA), as well as specific affective states of PA and NA.

Article Synopsis
  • An international network is being developed to survey scientists continuously, gathering extensive datasets about their opinions over time.
  • Local coordinators at participating institutions will send out brief survey invitations to scientists, utilizing a simple 10-second survey format with a single statement and a five-point Likert scale.
  • A recent study successfully engaged over 20,000 scientists, receiving 6,807 responses, which demonstrates the feasibility of quickly measuring global scientific opinion, potentially aiding in policy-making and enhancing public understanding.

Background: Falls and fall-related injuries remain a global challenge and threat to the health of older adults. Specific strength and balance exercises are effective in preventing falls among community-dwelling older adults. Nevertheless, provision of evidence-based fall prevention interventions to a broad population represents a healthcare challenge, indicating that new models for promoting exercise among community-dwelling older adults need to be addressed.
