MYB30 orchestrates systemic reactive oxygen signaling and plant acclimation
Light stress；MYB30 Reactive oxygen species Systemic acquired acclimation 50 Gene co-expression network
2024/1/11
Systemic acquired acclimation (SAA) is a key biological process essential for plant survival under conditions of abiotic stress. SAA was recently shown to be controlled by a rapid systemic signaling m...
Jasmonic acid and salicylic acid modulate systemic reactive oxygen species signaling during stress responses
long-distance arabidopsis acclimation combination ethylene light npr1
2023/11/16
Plants can send long-distance cell-to-cell signals from a single tissue subjected to stress to the entire plant. This ability is termed “systemic signaling” and is essential for plant acclimation to s...
The oxygen sensing mechanism of a triphenylamine-based cyclometalated platinum(II) complex
Oxygen sensing Luminescence mechanism Quenching
2023/3/1
Triphenylamine-based cyclometalated platinum(II) (TCP) emits phosphorescence at room temperature. The phosphorescence was quenched by oxygen molecule, which means that TCP is a good candidate for oxyg...
Rondaxe Lake in Herkimer County, New York, represents classic Adirondack Park waters. But over the last quarter-century, Rondaxe – like thousands of lakes in temperate zones around the world – has bee...
What if emergency medical personnel could treat a desperately ill patient in need of oxygen with a simple injection instead of having to rely on mechanical ventilation or rush to get them onto a heart...
Styrofoam egg cartons, hard plastic compact disc cases, red drinking cups and many other common products are composed of polystyrene, a type of plastic that makes up a third of landfill waste worldwid...
Comet 67P/Churyomov-Gerasimenko – arguably the most-studied comet in history – has yielded a cosmic surprise: It emits molecular oxygen drawn from its nucleus.
An electrochemical reaction that splits apart water molecules to produce oxygen is at the heart of multiple approaches aiming to produce alternative fuels for transportation. But this reaction has to ...
A new study co-led by a Cornell researcher has identified serpentinite – a green rock that looks a bit like snakeskin and holds fluids in its mineral structures – as a key driver of the oxygen recycli...
Researchers have found that the extinction at the end of the Permian period coincided with a sudden spike and subsequent drop in the ocean's oxygen content.
Sea ice kept oxygen from reaching deep ocean during last ice age, study finds（图）
Sea ice oxygen reaching deep ocean during ice age
2021/3/5
Extensive sea ice covered the world's oceans during the last ice age, preventing oxygen from penetrating into deep ocean waters and complicating the relationship between oxygen and carbon, a new study...

Organic matter bacteria doom sea stars oxygen depletion
2021/1/28
For more than seven years, a mysterious wasting disease has nearly killed off sea star populations worldwide. Many of these species are at the brink of extinction.New Cornell University-led resea...
Without oxygen, Earth's early microbes relied on arsenic to sustain life（图）
Without oxygen Earth early microbes relied arsenic sustain life
2020/10/16
Much of life on Earth today relies on oxygen to exist, but before oxygen was present on our planet, lifeforms likely used arsenic. The findings of the U.S. National Science Foundation-funded rese...
Volcanic activity and changes in Earth's mantle were key to rise of atmospheric oxygen（图）
Volcanic activity changes Earth mantle were key rise atmospheric oxygen
2020/6/19
Oxygen first accumulated in the Earth's atmosphere about 2.4 billion years ago, during the Great Oxidation Event. A long-standing puzzle has been that geologic clues suggest early bacteria were photos...
