How some tissues can "breathe" without oxygen
Humans need oxygen molecules for a process called cellular respiration, which takes place in our cells' mitochondria. Through a series of reactions called the electron transport chain, electrons are passed along in a sort of cellular relay race, allo.....»»
Hypoxia is widespread and increasing in the ocean off the Pacific Northwest coast, study shows
Low oxygen conditions that pose a significant threat to marine life are widespread and increasing in coastal Pacific Northwest ocean waters as the climate warms, a new study shows......»»
Regulating atomic Fe-Rh site distance for efficient oxygen reduction reaction
In a study published in the journal Science China Chemistry, the authors systematically design and investigate the site-distance effect of Fe-Rh atom catalysts (Fe-Rhx@NC) supported by N-doped graphene for ORR by an integrated theoretical and experim.....»»
Researchers use genetic engineering to create flood-tolerant plants
Adding too much water to your plants can damage them as much as not having enough water. In the environment, plants submerged under excessive rain have limited access to light and oxygen, which reduces or eliminates their ability to thrive. This pose.....»»
Jailbreaking an iPhone re-enables blood oxygen measurement on Apple Watch; August 2028 expiry
An interesting look behind the scenes of the court battle between Apple and health tech company Masimo reveals that jailbreaking an iPhone re-enables blood oxygen measurement on an Apple Watch. The same report notes that even if Apple doesn’t su.....»»

Jupiter"s moon Europa produces less oxygen than we thought—it may affect our chances of finding life there
Jupiter's icy moon Europa has long been thought of as one of the most habitable worlds in the Solar System. Now the Juno mission to Jupiter has directly sampled its atmosphere in detail for the first time. The results, published in Nature Astronomy,.....»»
How does a river breathe? The answer could lead to a better understanding of the global carbon cycle
Take a deep breath. Pay attention to how air moves from your nose to your throat before filling your lungs with oxygen. As you exhale your breath, a mix of oxygen and carbon dioxide leaves your nose and mouth......»»
The role of PbrChiA chitinase in ROS regulation and antifungal activity
Pear ring rot, a significant threat to pear production, is caused by Botryosphaeria dothidea, leveraging the complex dynamics of reactive oxygen species (ROS) during infection. Initially, plants employ their innate immune system, detecting pathogens.....»»
Jupiter’s icy moon Europa may be light on oxygen, lowering habitability hopes
New research pours cold water on the likelihood of Europa being habitable, as it seems that the moon produces less oxygen than previously thought......»»
How nitrogen has been underestimated in lake ecosystems
An ecological imbalance in a lake can usually be attributed to increased nutrient inputs. This results in increased phytoplankton growth, oxygen deficiency, toxic cyanobacterial blooms and fish deaths. Until now, controls in lake management have focu.....»»
Drying without dying: Tracing water scarcity coping mechanisms from mosses to flowering plants
Imagine you find the dried-up remains of a once green and lush philodendron on your bookshelf and realize you can't remember the last time you watered your houseplants. You soak the soil with water, hoping you can breathe life back into its desiccate.....»»
Eco-friendly catalyst and materials research explores pathways to renewable energy
The search for sustainable and affordable energy conversion technologies has highlighted the importance of the oxygen reduction and oxygen evolution reactions (ORR and OER). These processes are crucial for the efficiency of devices such as fuel cells.....»»
Controlling the microenvironment to promote wound healing and regeneration
The Korea Research Institute of Standards and Science has unveiled a new principle for controlling the microenvironment of biological tissues to promote wound healing and regeneration. This discovery holds significant promise for the development of w.....»»
The effects of primer pairs, PCR conditions, and peptide nucleic acid clamps on plant root fungal diversity assessment
Fungi are frequently found both around and within plant tissues (especially in roots) and are involved in both plant nutrient acquisition and resistance to pathogens. Thus, characterizing the diversity and composition of plant-associated fungal commu.....»»
Northwest Indiana residents, upset over refinery pollution, take complaints to public meeting
Bearing signs with slogans like "East Chicago demands clear air" and "IDEM, let us breathe," nearly 100 Northwest Indiana residents and environmental advocates gathered to voice anger and frustration at BP Whiting refinery at a public meeting held by.....»»
Earth"s early evolution: Fresh insights from rocks formed 3.5 billion years ago
Our Earth is around 4.5 billion years old. Way back in its earliest years, vast oceans dominated. There were frequent volcanic eruptions and, because there was no free oxygen in the atmosphere, there was no ozone layer. It was a dynamic and evolving.....»»
Scientists create method to bond hydrogels and other polymeric materials using chitosan
Hydrogels are versatile biomaterials conquering an increasing number of biomedical areas. Consisting of water-swollen molecular networks that can be tailored to mimic the mechanical and chemical features of various organs and tissues, they can interf.....»»
Researchers shed light on river resiliency to flooding
Researchers at the University of Nevada, Reno have completed one of the most extensive river resilience studies, examining how river ecosystems recover following floods. They developed a novel modeling approach that used data from oxygen sensors plac.....»»
Study finds oxygen rise in the tropical upper ocean during the Paleocene-Eocene Thermal Maximum
Oxygen is fundamental to sustaining life on Earth. The ocean gets its oxygen from its uppermost layers in contact with the atmosphere. As our planet continues to warm, the ocean is gradually losing its capacity to absorb oxygen, with severe consequen.....»»
SPNS2 found to be directly exporting S1P for signaling, can be inhibited
