RENAL‐CHIP: Rejection Evaluation via Non‐Invasive Analysis of Circulating Podocytes With Herringbone‐Chip Isolation Platform

open access: yesAdvanced Science, EarlyView.
RENAL‐CHIP converts 1 mL of peripheral blood into a biopsy‐equivalent readout of renal‐allograft fate. By magnetic capture and release of donor‐derived circulating podocytes through a herringbone microfluidic chip, 84% capture, 96% release and single‐cell RNA evidence of rejection‐specific immunity are achieved.

The particle dry deposition component of total deposition from air quality models: right, wrong or uncertain?

open access: yesTellus: Series B, Chemical and Physical Meteorology, 2019
Dry deposition is an important loss process for atmospheric particles and can be a significant part of total deposition estimates calculated for critical loads analyses. However, algorithms used in large-scale air quality and atmospheric chemistry models

Corals and Reef‐Dwelling Fish Regulate Carbon Storage and Cycling Processes in Coral Reef Ecosystems

open access: yesAdvanced Science, EarlyView.
Coral reefs are biodiversity hotspots, yet their role in carbon storage and cycling remains poorly understood. Using field surveys and modeling in the South China Sea, we reveal the overlooked potential of carbon storage in reef ecosystems and how reef fish, corals, and surface sediment jointly shape reef carbon reservoirs.
