Forced versus internal variability in Northern Hemisphere climate

Eos, Transactions American Geophysical Union, 2014
Some commonly used procedures do not correctly isolate the internal variability in the Northern Hemisphere climate system, a recent study argues. Mann et al. sought to separate the variability internal to the Northern Hemisphere temperature system from the external, or forced, variability driven by natural factors such as volcanic eruptions and ...

Scalable Polyelectrolyte Complex‐Based Sorbent With Hourly Sorption−Desorption Cycles for Multicyclic Atmospheric Water Harvesting in Arid Environments

Advanced Functional Materials, EarlyView.
A polyelectrolyte complex‐based sorbent is produced by scalable, environmentally benign aqueous phase inversion. Its porous, LiCl‐ and GO‐integrated architecture enables hourly adsorption−desorption cycles at low relative humidity (RH < 30%). A large‐scale prototype achieves multicyclic, solar‐driven atmospheric water harvesting of 1.37 L kg−1 day−1 ...

Evaluating the Role of Internal Climate Variability and Bias Adjustment Methods on Decadal Glacier Projections

Earth's Future
Glacier mass loss is one of the main contributors to sea‐level rise and poses challenges for future water resources. Refining glacier projections and sources of uncertainty thus supports climate adaptation and mitigation.

Radiative absorption enhancements by black carbon controlled by particle-to-particle heterogeneity in composition. [PDF]

, 2020
Black carbon (BC) absorbs solar radiation, leading to a strong but uncertain warming effect on climate. A key challenge in modeling and quantifying BC's radiative effect on climate is predicting enhancements in light absorption that result from internal ...

Oxygen Supply of Islets of Langerhans by Photosynthetically Active Microalgae in Bioprinted Co‐Cultures Maintains Their Function in a Hypoxic Environment

Advanced Healthcare Materials, EarlyView.
This study developed a bioprinted co‐culture system embedding rat pancreatic islets and Scenedesmus sp. microalgae spatially defined in close vicinity. Red light was found optimal to ensure microalgal photosynthesis while maintaining islet viability and functionality. A tailored co‐culture medium supported both cell types.

Controllable Dynamic Mechanical Cell Stimulation using Magnetically Actuated Artificial Cilia

Advanced Healthcare Materials, EarlyView.
This paper introduces a platform based on magnetic artificial cilia for providing controllable dynamic mechanical stimulation to single cells, suitable for investigating large cell populations and enabling live cell imaging. Proof‐of‐principle experiments show that cell morphology is strongly influenced by the artificial cilia, that cellular forces can
