A hybrid ice-mélange model based on particle and continuum methods [PDF]

open access: yesThe Cryosphere
Ice mélange, a composite of sea ice and icebergs, can have a major influence on sea-ice–ocean interactions. However, ice mélange has not been represented in climate models because numerically efficient realizations do not exist.

Melting and fragmentation laws from the evolution of two large Southern Ocean icebergs estimated from satellite data [PDF]

open access: yesThe Cryosphere, 2018
The evolution of the thickness and area of two large Southern Ocean icebergs that have drifted in open water for more than a year is estimated through the combined analysis of altimeter data and visible satellite images.

The tip of the iceberg [PDF]

open access: yesBMJ, 1994
I palpated a lump in my epigastrium nine months to the day after delivering my third child when I was 43. I was not alarmed since I had had an easy pregnancy and returned to work two months later as a consultant pathologist. I felt well. True, I was tired, but who is not with a full time job and three children, especially a small baby who still woke me

Icebergs boost phytoplankton growth in the Southern Ocean [PDF]

open access: yes, 2008
Icebergs which calve from the Antarctic ice shelves and drift in the Southern Ocean deliver fresh water, dust and minerogenic particles to the surface ocean along the iceberg's path.

Antarctic icebergs distributions 1992-2014

open access: yes, 2016
Basal melting of floating ice shelves and iceberg calving constitute the two almost equal paths of freshwater flux between the Antarctic ice cap and the Southern Ocean.

Comprehensive In Vitro Profiling Demonstrates Successful Immune Evasion of Bioengineered Immune‐Shielded Heart Valves

open access: yesAdvanced Healthcare Materials, EarlyView.
Living donor heart valves offer superior durability for pediatric patients but trigger immune rejection. Lentiviral delivery of viral immune‐evasion genes US2 and Serpin b9 into donor valve cells and valve tissue suppresses HLA expression, reduces PBMC clustering and cytotoxic killing, and induces transcriptional immune‐tolerance programs, paving the ...

Unveiling the Taxonomic Diversity and Unprecedented Biosynthetic Treasure of the Phylum Myxococcota

open access: yesAdvanced Science, EarlyView.
Natural products remain vital sources of therapeutics, and the phylum Myxococcota constitutes an especially rich reservoir for them. Based on decades of microbiological efforts, we present 154 new Myxococcota genomes and revise taxonomy quadrupling the number of families and genera.

Effects of Environmental and Health Information on Willingness to Pay for Local and Organic Foods in Taiwan

open access: yesAgribusiness, EarlyView.
ABSTRACT Using a lab‐in‐the‐field experiment, we investigate how providing information about food miles and pesticide residue influences willingness to pay (WTP) for potatoes among 407 shoppers in Taiwan, split between a supermarket and a farmers market.

Fluorescent cAMP Analogs: Enzymatic Synthesis, Unexpected Photophysical Behavior and Protein Kinase A Recognition

open access: yesAngewandte Chemie, EarlyView.
Cyclic adenosine monophosphate (cAMP) is a key cellular second messenger. Adenylyl cyclase converts emissive isomorphic nucleoside triphosphates into fluorescent cAMPs. cthAMP displays unusually high brightness compared to thATP, its precursor, enabling real‐time monitoring of enzymatic reactions.
