Early-twentieth-century cold bias in ocean surface temperature observations.

The observed temperature record, which combines sea surface temperatures with near-surface air temperatures over land, is crucial for understanding climate variability and change. However, early records of global mean surface temperature are uncertain owing to changes in measurement technology and practice, partial documentation, and incomplete spatial coverage. Here we show that existing estimates of ocean temperatures in the early twentieth century (1900-1930) are too cold, based on independent statistical reconstructions of the global mean surface temperature from either ocean or land data.

Social media in pathology and laboratory medicine: A systematic review.

The use of social media platforms in pathology and medical laboratory science has increased in recent years, revolutionizing the way professionals in these fields interact, disseminate information, and collaborate. To gain an understanding of the current landscape regarding social media use in pathology and medical laboratory science, a novel systematic review was conducted. A search of PubMed, Medline, Embase, and Scopus was performed to identify articles evaluating social media use within pathology and medical laboratory science.

Realtime and noninvasive assessment of endotracheal tube displacement using near-infrared and visible cameras.

Endotracheal tube (ETT) intubation is a medical procedure routinely used for achieving mechanical ventilation in critically ill patients. Appropriate ETT placement is crucial as undetected tube migration may cause multiple complications or even fatalities. Therefore, prompt detection of unplanned movement of the ETT and immediate action to restore proper placement are essential to ensure patient safety.

High-temperature carbon dioxide capture in a porous material with terminal zinc hydride sites.

Carbon capture can mitigate point-source carbon dioxide (CO) emissions, but hurdles remain that impede the widespread adoption of amine-based technologies. Capturing CO at temperatures closer to those of many industrial exhaust streams (>200°C) is of interest, although metal oxide absorbents that operate at these temperatures typically exhibit sluggish CO absorption kinetics and instability to cycling. Here, we report a porous metal-organic framework featuring terminal zinc hydride sites that reversibly bind CO at temperatures above 200°C-conditions that are unprecedented for intrinsically porous materials.

Head and neck cancer mortality in the United States: Regional differences in hospice use and place of death.

Background: With more than 15,000 annual deaths from head and neck cancer (HNC), an important aspect of end-of-life care for these patients is place of death. Recent evidence suggests an increasing preference for home/hospice at end of life; however, it is unclear whether there is variation in home/hospice use based on region or urban status. We described differences in the place of death of HNC patients based on their region and urban status.
