Article Synopsis
- Global environmental changes have led to significant increases in lake surface temperatures, affecting ecosystem dynamics worldwide.
- Researchers created a comprehensive database of summer lake temperatures for 291 lakes from 1985 to 2009, integrating both satellite data and in-situ measurements.
- The dataset also includes key climatic and geographical factors that impact lake temperatures, providing a baseline for understanding the long-term effects of environmental change on inland water bodies.

Article Abstract
Global environmental change has influenced lake surface temperatures, a key driver of ecosystem structure and function. Recent studies have suggested significant warming of water temperatures in individual lakes across many different regions around the world. However, the spatial and temporal coherence associated with the magnitude of these trends remains unclear. Thus, a global data set of water temperature is required to understand and synthesize global, long-term trends in surface water temperatures of inland bodies of water. We assembled a database of summer lake surface temperatures for 291 lakes collected in situ and/or by satellites for the period 1985-2009. In addition, corresponding climatic drivers (air temperatures, solar radiation, and cloud cover) and geomorphometric characteristics (latitude, longitude, elevation, lake surface area, maximum depth, mean depth, and volume) that influence lake surface temperatures were compiled for each lake. This unique dataset offers an invaluable baseline perspective on global-scale lake thermal conditions as environmental change continues.

Shocked quartz at the Younger Dryas onset (12.8 ka) supports cosmic airbursts/impacts contributing to North American megafaunal extinctions and collapse of the Clovis technocomplex.

Shocked quartz grains are an accepted indicator of crater-forming cosmic impact events, which also typically produce amorphous silica along the fractures. Furthermore, previous research has shown that shocked quartz can form when nuclear detonations, asteroids, and comets produce near-surface or "touch-down" airbursts. When cosmic airbursts detonate with enough energy and at sufficiently low altitude, the resultant relatively small, high-velocity fragments may strike Earth's surface with high enough pressures to generate thermal and mechanical shock that can fracture quartz grains and introduce molten silica into the fractures.

Red blood cell (RBC) size constrains the rate of diffusion of gases between (i) the environment and the capillary beds of the gas exchanger and (ii) the blood and organs. In birds, small RBCs with a high surface area to volume ratio permit a high O diffusion capacity and facilitate sustained, vigorous exercise. Unfortunately, our knowledge of archosaur cardiovascular evolution is incomplete without fossilized RBCs and blood vessels.

This study explores the extraction of polysaccharides from Nostoc commune Vauch. using ultrasonic-assisted three-phase partitioning with deep eutectic solvents (UA-TPP-DES). Response surface methodology was used to determine the optimized UA-TPP-DES conditions as follows: a 1: 2 M ratio of lauric acid to terpineol, 30 min of ultrasonication at 60 °C with 100 W power, 20 % moisture content, 20 % w/w (NH)SO concentration, and a 2: 1 top-to-bottom phase volume ratio.

Background: Although blood group variation was first described over a century ago, our understanding of the genetic variation affecting antigenic expression on the red blood cell surface in many populations is lacking. This deficit limits the ability to accurately type patients, especially as serological testing is not available for all described blood groups, and targeted genotyping panels may lack rare or population-specific variants.
Study Design And Methods: Here, we perform serological assays across 24 antigens and whole genome sequencing on 100 Omanis, a population underrepresented in genomic databases.

The production of phosphogypsum (PG), calcium carbide slag (CS), and red mud (RM) in global industrial development imposes serious environmental issues. Utilizing CS and PG as curing agents and incorporating RM as a soil substitute can facilitate the solid waste resource utilization. However, few studies have investigated the synergistic effects of PG and CS on the stabilization of RM and soil.
