Designing exceptional gas-separation polymer membranes using machine learning
The field of polymer membrane design is primarily based on empirical observation, which limits discovery of new materials optimized for separating a given gas pair. Instead of relying on exhaustive experimental investigations, we trained a machine learning (ML) algorithm, using a topological, path-based hash of the polymer repeating unit. We used a limited set of experimental gas permeability dat

Food web controls on mercury fluxes and fate in the Colorado River, Grand Canyon
Mercury (Hg) biomagnification in aquatic food webs is a global concern; yet, the ways species traits and interactions mediate these fluxes remain poorly understood. Few pathways dominated Hg flux in the Colorado River despite large spatial differences in food web complexity, and fluxes were mediated by one functional trait, predation resistance. New Zealand mudsnails are predator resistant and a

The activity of sulfono-{gamma}-AApeptide helical foldamers that mimic GLP-1
Existing long α-helix mimicking necessitates the retention of most natural amino acid residues to maintain their biological activity. Here, we report the exploration of helical sulfono–AApeptides with entire unnatural backbones for their ability to structurally and functionally mimic glucagon-like peptide 1 (GLP-1). Our findings suggest that efficient construction of novel GLP-1 receptor (GLP-1R

From force-responsive molecules to quantifying and mapping stresses in soft materials
Directly quantifying a spatially varying stress in soft materials is currently a great challenge. We propose a method to do that by detecting a change in visible light absorption. We incorporate a spiropyran (SP) force–activated mechanophore cross-linker in multiple-network elastomers. The random nature of the network structure of the polymer causes a progressive activation of the SP force probe

Legionella effector AnkX displaces the switch II region for Rab1b phosphocholination
The causative agent of Legionnaires disease, Legionella pneumophila , translocates the phosphocholine transferase AnkX during infection and thereby posttranslationally modifies the small guanosine triphosphatase (GTPase) Rab1 with a phosphocholine moiety at S76 using cytidine diphosphate (CDP)–choline as a cosubstrate. The molecular basis for Rab1 binding and enzymatic modification have remained

Targeting pulmonary tumor microenvironment with CXCR4-inhibiting nanocomplex to enhance anti-PD-L1 immunotherapy
Anti–programmed cell death 1 ligand 1 (PD-L1) therapy is extraordinarily effective in select patients with cancer. However, insufficient lymphocytic infiltration, weak T cell–induced inflammation, and immunosuppressive cell accumulation in the tumor microenvironment (TME) may greatly diminish the efficacy. Here, we report development of the FX@HP nanocomplex composed of fluorinated polymerized CX

A multistage assembly/disassembly strategy for tumor-targeted CO delivery
CO gas molecule not only could selectively kill cancer cells but also exhibits limited anticancer efficacy because of the lack of active tumor-targeted accumulation capability. In this work, a multistage assembly/disassembly strategy is developed to construct a new intelligent nanomedicine by encapsulating a mitochondria-targeted and intramitochondrial microenvironment–responsive prodrug (FeCO-TP

Bioinorganic hybrid bacteriophage for modulation of intestinal microbiota to remodel tumor-immune microenvironment against colorectal cancer
Mounting evidence suggests that the gut microbiota contribute to colorectal cancer (CRC) tumorigenesis, in which the symbiotic Fusobacterium nucleatum ( Fn ) selectively increases immunosuppressive myeloid-derived suppressor cells (MDSCs) to hamper the host's anticancer immune response. Here, a specifically Fn -binding M13 phage was screened by phage display technology. Then, silver nanoparticles

ATAC-seq identifies thousands of extrachromosomal circular DNA in cancer and cell lines
Extrachromosomal circular DNAs (eccDNAs) are somatically mosaic and contribute to intercellular heterogeneity in normal and tumor cells. Because short eccDNAs are poorly chromatinized, we hypothesized that they are sequenced by tagmentation in ATAC-seq experiments without any enrichment of circular DNA. Indeed, ATAC-seq identified thousands of eccDNAs in cell lines that were validated by inverse

Dissolved oxygen from microalgae-gel patch promotes chronic wound healing in diabetes
Chronic wounds in diabetes undergo a lifetime risk of developing into diabetic foot ulcers. Oxygen is crucial to wound healing by regulating cell proliferation, migration, and neovascularization. However, current oxygen therapies, including hyperbaric oxygen (HBO) and topical gaseous oxygen (TGO), mainly employ gaseous oxygen delivery, which is much less effective in penetrating the skin.

Study the effect of long-term oxygen deficiency
Researchers at Luleå University of Technology have developed a method to study how muscle cells in the blood vessels of the lung permanently contract because of long-term oxygen deficiency. This phenomenon leads to increased pressure in the vessels of the lung and the strain on the heart increases. The effect is evident in lung diseases such as chronic obstructive pulmonary disease (COPD) and the

Vissa måste äta mer socker för att känna söt smak – och får mer karies
Personer med en speciell genvariant behöver äta mer socker för att känna söt smak, och de får också mer karies i tänderna. Det visar en ny avhandling vid Umeå universitet. Avhandlingen visar också att även personer som inte har den vanligaste kariesbakterien i munnen kan drabbas. – En slutsats är att man skulle kunna använda smaktest eller gentest för att identifiera personer som är i riskgrupp o

A study highlights the African affinities of the southwestern European Acheulean
The Centro Nacional de Investigación sobre la Evolución Humana (CENIEH) is the co-leader of a study published this week in the Journal of Paleolithic Archaeology that presents a synthesis of human occupation in the Iberian Peninsula Atlantic margin during the Early and Middle Paleolithic, and highlights the African affinities of Acheulean industry in southwestern Europe.

Biprodukter gör mjölkkor mer produktiva
När mjölkkor utfodras med mycket spannmål och bönor som komplement till vallfoder äter de mer potentiella livsmedel än vad de producerar i form av mjölk. Men om man ersätter spannmål och bönor med biprodukter, såsom betfiber, drank, rapsmjöl och kli, så producerar korna mycket mer livsmedel än vad de äter. Människor och lantbrukets djur konkurrerar om de proteinfoder som jorden kan producera. Joh

Materials science group loses four papers, has four more flagged
A Springer Nature journal has retracted four papers by a group of materials scientists in France, Spain and Tunisia, and slapped expressions of concern on four more. All eight papers, from Journal of Materials Science: Materials in Electronics, share three common authors: Abdelmajid Lassoued, Salah Ammar, and Abdellatif Gadri, of Université de Gabès in Tunisia. … Continue reading

Purification of wastewater may lead to an imbalance between nitrogen and phosphorus
The amount of nitrogen and phosphorus in surface water has been reduced through purification of wastewater. Nonetheless, toxic algae blooms still flourish frequently. Because the purification plants are better at removing phosphorus than nitrogen, the balance between these two elements is shifting on a global scale. This results in a comparatively high level of nitrogen in the purified water, whic
