Article Synopsis
  • Angiosperms are vital for ecosystems and human life, making it important to understand their evolutionary history to grasp their ecological dominance.
  • The study builds an extensive tree of life for about 8,000 angiosperm genera using 353 nuclear genes, significantly increasing the sampling size and refining earlier classifications.
  • The findings reveal a complex evolutionary history marked by high gene tree conflict and rapid diversification, particularly during the early angiosperm evolution, with shifts in diversification rates linked to global temperature changes.

A key goal for cognitive neuroscience is to understand the neurocognitive systems that support semantic memory. Recent multivariate analyses of neuroimaging data have contributed greatly to this effort, but the rapid development of these novel approaches has made it difficult to track the diversity of findings and to understand how and why they sometimes lead to contradictory conclusions. We address this challenge by reviewing cognitive theories of semantic representation and their neural instantiation.

The world's herbaria collectively house millions of diverse plant specimens, including endangered or extinct species and type specimens. Unlocking genetic data from the typically highly degraded DNA obtained from herbarium specimens was difficult until the arrival of high-throughput sequencing approaches, which can be applied to low quantities of severely fragmented DNA. Target enrichment involves using short molecular probes that hybridise and capture genomic regions of interest for high-throughput sequencing.

The potential role for video tape education in gastroenterology is discussed. The need for material to inform patients about their diagnoses is widely acknowledged and educators need to take advantage of modern techniques. Studies in general practice, diabetes care, and asthma care have found that videos have significant benefits when compared with conventional techniques.

To investigate patients' views and expectations when attending outpatient clinics a questionnaire-based study was performed. The questionnaires asked about appointment systems, continuity of care, staff appearance, chaperons and medical students. Patients wanted fixed appointment times, to see the same doctor on successive visits, for the staff to be formally dressed and to have chaperons during examination.
