H2O2 repurposes plant O2 sensing to regulate post-hypoxia responses - Nature

H2O2 repurposes plant O2 sensing to regulate post-hypoxia responses - Nature

Experiments in Arabidopsis demonstrate that group VII ethylene response factors show differential responses to different stimuli, enabling plants in flood-prone environments to adapt to both submergence-induced hypoxia and reoxygenation upon desubmergence.

NASA shares iPhone video capturing Earthshine from Orion during Artemis II - 9to5Mac

The iPhone footage taken during the mission's second day shows how Earth’s reflected light illuminates the Orion cabin. Watch it below.

Astrocytes connect specific brain regions through plastic networks - Nature

Astrocytes connect specific brain regions through plastic networks - Nature

Communication between distant brain regions is mediated by plastic networks of gap junction-coupled astrocytes.

A pro-carcinogenic bacterial toxin binds claudin-4 to cleave E-cadherin - Nature

A pro-carcinogenic bacterial toxin binds claudin-4 to cleave E-cadherin - Nature

CRISPR screening shows that claudin-4 is a receptor for the pro-carcinogenic B. fragilis toxin on colonic epithelial cells, and that this interaction promotes cleavage of E-cadherin, leading to epithelial barrier disruption and inflammation.

150-Year-Old Fossil Uncovers a Crucial Piece of Coelacanth Evolution, Bridging a 50-Million-Year Gap - Indian Defence Review

150-Year-Old Fossil Uncovers a Crucial Piece of Coelacanth Evolution, Bridging a 50-Million-Year Gap - Indian Defence Review

A 150-year-old fossil at London’s Natural History Museum has revealed a new species of coelacanth, filling a critical gap in the fish's evolutionary timeline.

Chromosomal fusions trigger rediploidization of autopolyploid genomes - Nature

Chromosomal fusions trigger rediploidization of autopolyploid genomes - Nature

Genomic data from snow carps reveal that the fusion of chromosomes initiates rediploidization following whole-genome duplication.

Myosin forces remodel F-actin for mechanosensitive protein recognition - Nature

Myosin forces remodel F-actin for mechanosensitive protein recognition - Nature

Structural studies demonstrate that myosin generates forces that cause structural changes in actin, modulating cooperative binding by α-catenin and thus signal transduction and intercellular communication via adhesion complexes.

Soundwaves settle debate about elusive quantum particle - Phys.org

It was a head-spinning discovery. In 2018, researchers in Japan claimed to find concrete evidence of an elusive particle, a Majorana fermion, in a quantum spin liquid called ruthenium trichloride. Majoranas are highly sought-after by quantum materials scienti…
