The evolution of new combinations of bacterial properties contributes to biodiversity and the emergence of new diseases. We investigated the capacity for bacterial divergence with a chemostat culture of Escherichia coli. A clonal population radiated into more than five phenotypic clusters within 26 days, with multiple variations in global regulation, metabolic strategies, surface properties, and nutrient permeability pathways. Most isolates belonged to a single ecotype, and neither periodic selection events nor ecological competition for a single niche prevented an adaptive radiation with a single resource. The multidirectional exploration of fitness space is an underestimated ingredient to bacterial success even in unstructured environments.

Buildings are increasingly being conceived as dynamic systems that interact with their surroundings to optimize energy performance and enhance occupant comfort. This evolution in architectural thinking draws inspiration from biological systems, where the building envelope functions like a thermally responsive "skin" that can autonomously adjust its optical and thermal properties in response to environmental temperature changes. Among the many approaches developed for smart building envelopes, passive thermoresponsive spectral modulation systems have attracted growing interest due to their structural simplicity and low energy demand.

In the recent years, the clinical stage where the cancer has spread beyond the primary site, but has not yet metastasised extensively, and which is known as oligometastatic disease (OMD), has become an object of interest to radiation oncologists. OMD is a kind of an "umbrella term" for a variety of clinical situations. This review focuses on the role of radiotherapy (RT) in the treatment of oligometastatic non-small cell lung cancer (OM-NSCLC).

Urinary bladder cancer contributes significantly to the global cancer burden and is more prevalent in the developed world. We present the case of a 54-year-old male smoker who underwent transurethral resection of bladder tumor and consequent trimodality therapy (induction chemotherapy followed by concomitant chemo-radiotherapy). His disease was staged at cT3N0M0.

Background: Integrating a practice-based curriculum to cover essential aspects of patient safety and quality improvement (PSQI) in the outpatient setting can improve resident understanding and engagement in future projects within a radiation oncology residency program.
Objectives: To develop and pilot a workshop-based PSQI curriculum to lead residents through a simulated departmental quality improvement project and enhance understanding regarding tools and metrics used within a PSQI framework.
Methods: This pilot project was completed in the 2023-2024 academic year, with 13 residents in one radiation oncology program.

Purpose This planning study aimed to clarify the significance of inverse planning with variable dose rate (VDR) and the segment shape optimization (SSO) in the quality and efficiency of dynamic conformal arcs (DCA) using the high-definition dynamic radiosurgery (HDRS) platform for stereotactic radiosurgery (SRS) of single brain metastases (BMs). Materials and methods Twenty clinical BMs were included, with the gross tumor volume (GTV) ranging from 0.33 cc to 48.
