Chemists use oxygen, copper "scissors" to make cheaper drug treatments possible
Drugs to treat cancer are often very expensive to produce, resulting in high costs for the patients who need them. Thanks to pathbreaking research by UCLA chemists, led by organic chemistry professor Ohyun Kwon, the price of drug treatments for cance.....»»
Investigating solid-state atomic hydrogen as a potential hydrogen therapy strategy
The overexpression of reactive oxygen and nitrogen species (RONS) is closely associated with the onset and progression of diverse chronic diseases, such as cancer, Alzheimer's disease, and chronic diabetic ulcers. Hydrogen therapy, as an emerging and.....»»
Decoding anthocyanin impact: Genetic insights into plant defense and growth trade-offs
Anthocyanins are key pigments in plants for plant resistance to abiotic stress. It can provide photoprotection by potentially absorbing visible light and scavenging reactive oxygen species (ROS) when biotic stress occurs. However, comparative studies.....»»
More than meows: How bacteria help cats communicate
Many mammals, from domestic cats and dogs to giant pandas, use scent to communicate with each other. A new study from the University of California, Davis shows how domestic cats send signals to each other using odors derived from families of bacteria.....»»
Researchers improve water splitting reaction for green hydrogen gas production
Green hydrogen (or H2) produced from renewable energy resources is the fuel of a decarbonized future. Electrolysis, or splitting of water into oxygen and hydrogen with the help of an electrochemical cell, is one of the most popular ways of producing.....»»
Decoding the genetics of ascorbic acid: A deep dive into strawberry"s Vitamin C content and its environmental factors
Vitamin C, also known as ascorbic acid (AsA), is a prevalent antioxidant found in various organisms, notably plants and animals. Functionally, AsA plays a variety of roles, from enzyme cofactor to safeguarding against oxidative damage during photosyn.....»»
Adapting to climate change: Mutation enables flour beetles to speed up their development
Leiden biologists have found a mutation in flour beetles that allows them to speed up their development. They think that more insects can change their growth rate, which could help them adjust to climate change. The study has been published in Nature.....»»
Adding oxygen to a lake to explore methane emissions
Lakes around the world emit methane to the atmosphere, accounting for up to 19% of total global emissions of this potent greenhouse gas. Most of the methane in lakes comes from microbes in the lake bed that consume dissolved organic matter for susten.....»»
Presence of atomic oxygen confirmed on both day and night sides of Venus
A multi-institutional team of astrophysicists from Germany has made the first direct observation of oxygen atoms in the day side atmosphere of Venus. In their project, reported in the journal Nature Communications, the group studied data from the Str.....»»
Extracellular vesicles captured by sustainable wood cellulose-based nanofiber may identify and improve cancer treatment
A research team in Japan, led by Nagoya University's Akira Yokoi, has developed an innovative technique using cellulose nanofiber (CNF) sheets derived from wood cellulose to capture extracellular vesicles (EVs) from fluid samples and even organs duri.....»»
New microfossils suggest earlier rise in complex life
Microfossils from Western Australia may capture a jump in the complexity of life that coincided with the rise of oxygen in Earth's atmosphere and oceans, according to an international team of scientists......»»
Once they have laid their eggs, fish become "young" again: Study
The physical relief—in body weight—that temperate fish like cod and Atlantic herring experience after they spawn for the first time allows them to breathe in more oxygen and develop a voracious appetite, all of which leads to a rapid increase in.....»»
Apple Watch Series 10 will monitor blood pressure, detect sleep apnea
A new report says that after a decade working on health features like blood pressure monitoring, Apple will be ready to add it to 2024's Apple Watch Series 10.An Apple Watch showing a blood oxygen reading.An Apple Watch blood pressure sensor has been.....»»
Tuning properties of membrane and catalyst layers optimizes reactors for fuel cells and more
Ethylene is a chemical widely used as a feedstock for producing polymers and industrial chemicals. Oxidative coupling of methane (OCM) is a promising, energy-efficient way of creating ethylene from natural gas by reacting methane with oxygen. However.....»»
Mammalian cells may consume bacteria-killing viruses to promote cellular health
Bacteriophages, also called phages, are viruses that infect and kill bacteria, their natural hosts. But from a macromolecular viewpoint, phages can be viewed as nutritionally enriched packets of nucleotides wrapped in an amino acid shell......»»
Oxygen vacancy boosting Fenton reaction: A novel approach to fight bacterial infection in bone scaffold
The field of artificial bone transplantation has faced a significant barrier: bacterial infection, a common culprit that often leads to transplant failure and, in severe cases, devastating consequences such as amputation......»»
A layered lake reveals how oxygen built up in our atmosphere billions of years ago
Little Deming Lake doesn't get much notice from visitors to Itasca State Park in Minnesota. There's better boating on nearby Lake Itasca, the headwaters of the Mississippi River. My colleagues and I need to maneuver hundreds of pounds of equipment do.....»»
Enzyodynamic therapy at nanoscale
Enzyodynamic therapy (EDT) is a new type of reactive oxygen species (ROS)-related dynamic therapeutic modality, which adequately utilizes the enzyme-triggered catalytic reactions in living organisms and achieves disease treatment through controlling.....»»
