Inefficient transfer of diatoms through the subpolar Southern Ocean twilight zone.

The Southern Ocean, a region highly vulnerable to climate change, plays a vital role in regulating global nutrient cycles and atmospheric CO via the biological carbon pump. Diatoms, photosynthetically active plankton with dense opal skeletons, are key to this process as their exoskeletons are thought to enhance the transfer of particulate organic carbon to depth, positioning them as major vectors of carbon storage. Yet conflicting observations obscure the mechanistic link between diatoms, opal and particulate organic carbon fluxes, especially in the twilight zone where greatest flux losses occur.

Using natural language processing to identify emergency department patients with incidental lung nodules requiring follow-up.

Objectives: For emergency department (ED) patients, lung cancer may be detected early through incidental lung nodules (ILNs) discovered on chest CTs. However, there are significant errors in the communication and follow-up of incidental findings on ED imaging, particularly due to unstructured radiology reports. Natural language processing (NLP) can aid in identifying ILNs requiring follow-up, potentially reducing errors from missed follow-up.

The reversible capillary field effect transistor: a capillaric element for autonomous flow switching.

New flow control elements in capillaric circuits are key to achieving ever more complex lab-on-a-chip functionality while maintaining their autonomous and easy-to-use nature. Capillary field effect transistors valves allow for flow in channels to be restricted and cut off utilising a high pressure triggering channel and occluding air bubble. The reversible capillary field effect transistor presented here provides a new element that can restore fluid flow in closed microchannels autonomous circuit feedback.

Emergence of antibiotic-specific phenotypes during prolonged treatment of mice.

A major challenge in tuberculosis (TB) therapeutics is that antibiotic exposure leads to changes in the physiology of (), which may enable the pathogen to withstand treatment. While antibiotic-treated has been evaluated in experiments it is unclear if and how long-term treatment with diverse antibiotics with varying treatment-shortening activity (sterilizing activity) affects physiologic processes differently. Here, we used SEARCH-TB, a pathogen-targeted RNA-sequencing platform, to characterize the transcriptome in the BALB/c high-dose aerosol infection mouse model following 4 weeks of treatment with three sterilizing and three non-sterilizing antibiotics.
