Article Synopsis
- Newborn dairy calves struggle with cold stress when transitioning from the womb to colder temperatures, making it vital to understand their temperature preferences in winter conditions.
- The study evaluated the preferred inside hutch temperature of calves by allowing them to choose among 4 hutches with varying heat lamp configurations, alongside observing their lying behavior over two phases.
- Results showed that calves spent 90% of their time inside the hutches with no strong temperature preference, but indicated a need for shelter in winter, suggesting that environmental conditions like bedding and milk supply play a role in their comfort.
Fine-Tuning Genetic Circuits via Host Context and RBS Modulation.
ACS Synth Biol
January 2025
Faculty of Biosciences, Fisheries and Economics, UiT─The Arctic University of Norway, 9019 Tromsø, Norway.
The choice of organism to host a genetic circuit, the chassis, is often defaulted to model organisms due to their amenability. The chassis-design space has therefore remained underexplored as an engineering variable. In this work, we explored the design space of a genetic toggle switch through variations in nine ribosome binding site compositions and three host contexts, creating 27 circuit variants.

Radiative thermal management technologies that utilize thermal radiation from nano/microstructure for cooling and heating have gained significant attention in sustainable energy research. Passive radiative cooling and solar heating operate continuously, which may lead to additional heating or cooling energy consumption due to undesired cooling or heating during cold nighttime/winters or hot daytime/summers. To overcome the limitation, recent studies have focused on developing radiative thermal management technologies that can toggle radiative cooling on and off or possess switchable dual cooling and heating modes to realize sustainable and efficient thermal management.

One key aspect for the development of functional molecular electronic devices is the ability to precisely tune and reversibly switch the conductance of individual molecules in electrode-molecule-electrode junctions in response to external stimuli. In this work, we present a new approach to access molecular switches by deliberately controlling the flexibility in the molecular backbone. We here describe two new conductance switches based on bis(triarylamines) that rely on the reversible toggling between two conformers, each associated with vastly different conductances.
