The aviation industry's growing interest in renewable jet fuel has encouraged the exploration of alternative oilseed crops. Replacing traditional fossil fuels with a sustainable, domestically sourced crop can substantially reduce carbon emissions, thus mitigating global climate instability. Pennycress (Thlaspi arvense L.

Background: Health impacts of pediatric fruit and vegetable prescription programs (FVPPs) are unclear. This study assessed whether exposure to an FVPP that provided $15 produce prescriptions during pediatric visits was associated with differences in child diet, food security, physical activity, weight status, and blood pressure.

Methods: This cross-sectional analysis included data from caregiver-child dyads with varying levels of exposure to the FVPP.

Article Synopsis
  • Men of African descent experience the highest rates of prostate cancer, but the genetic factors behind this have not been thoroughly explored.
  • Researchers analyzed genetic data from nearly 4,000 prostate cancer cases and over 3,500 controls across several African countries to identify specific genetic associations related to the disease.
  • The study found 15 significant genetic associations, including four new ones, highlighting that genetic variation in prostate cancer is influenced by unique African alleles, suggesting that more research in diverse populations is crucial for understanding cancer genetics.

Unlabelled: Microorganisms with simplified genomes represent interesting cell chassis for systems and synthetic biology. However, genome reduction can lead to undesired traits, such as decreased growth rate and metabolic imbalances. To investigate the impact of genome reduction on strain DGF-298, a strain in which ~ 36% of the genome has been removed, we reconstructed a strain-specific metabolic model (AC1061), investigated the regulation of gene expression using iModulon-based transcriptome analysis, and performed adaptive laboratory evolution to let the strain correct potential imbalances that arose during its simplification.

Following introgression, Neanderthal DNA was initially purged from non-African genomes, but the evolutionary fate of remaining introgressed DNA has not been explored yet. To fill this gap, we analyzed 30,780 admixed genomes with African-like ancestry from the All of Us research program, in which Neanderthal alleles encountered novel genetic backgrounds during the last 15 generations. Observed amounts of Neanderthal DNA approximately match expectations based on ancestry proportions, suggesting neutral evolution.
