The circumstances under which species diversify to genetically distinct lineages is a fundamental question in biology. Atlantic herring (Clupea harengus) is an extremely abundant zooplanktivorous species that is subdivided into multiple ecotypes that differ regarding spawning time and genetic adaption to local environmental conditions such as temperature, salinity, and light conditions. Here we show using whole genome analysis that multiple populations of piscivorous (fish-eating) herring have evolved sympatrically after the colonization of the brackish Baltic Sea within the last 8000 years postglaciation.

Objectives: To assess whether and to what extent asthma exacerbations affect changes in PROMS over time and asthma-specific PROMs can predict exacerbations in adult patients with severe asthma in usual care.
Methods: Data of 421 patients with severe asthma (62% female; mean age 51.
Low oxygen tension (PO), characterizes the tissue environment of tumors. The colorectal tumor line Colo205, grown under reduced oxygen tension expresses a novel αDβ1 integrin, which forms a cell surface complex with hemoglobin δ. This resulted in high local affinity for oxygen, which increased cell adhesion as compared with cells grown under normal oxygen tension.

- - This study examines how the ionosphere on Mars is affected by crustal magnetic fields and solar wind pressure using data from the MAVEN spacecraft's Langmuir Probe and Waves instrument.
- - Researchers found that electron density decreases when comparing the solar wind's dynamic pressure to the magnetic pressure of Mars' crustal fields, indicating an inverse relationship.
- - Different magnetic field configurations change the behavior of electron density, with lower densities observed in certain topologies, suggesting that solar wind interactions and magnetic forces play a complex role in shaping the Martian atmosphere.
Zinc finger CCCH containing 11A (ZC3H11A) is a stress-induced protein that is upregulated in various conditions such as heat shock and virus infection. It has also been reported to be upregulated in certain cancers. The aim of this study was to evaluate the feasibility of targeting ZC3H11A as a therapeutic approach for cancer treatment, using nuclease-resistant, affinity-enhanced antisense oligonucleotide (ASO).
