Over the past few decades, scientists have paid special attention to studying novel and natural hydrocolloids due to the growing demand for ready meals, public awareness on the importance of natural fibers in daily diets, and their wide range of application, especially in foods, pharmaceuticals and herbal medicine. Moreover, natural hydrocolloids are preferred to biotechnologic ones (e.g., gell...

Observed increases in ocean heat content (OHC) and temperature are robust indicators of global warming during the past several decades. We used high-resolution proxy records from sediment cores to extend these observations in the Pacific 10,000 years beyond the instrumental record. We show that water masses linked to North Pacific and Antarctic intermediate waters were warmer by 2.1 ± 0.4°C and...
