Hydrogen-producing enzyme protects itself against oxygen
An international research team from the Photobiotechnology Research Group at Ruhr-Universität Bochum (RUB) led by Professor Thomas Happe and the Laboratoire de Bioénergétique et Ingénierie des Protéines (CNRS) in Marseille has been able to get t.....»»
Discovery of a tRNA modification enzyme that also acts on nucleosides
The genetic information on DNA is transcribed into messenger RNA (mRNA) and translated to the amino acid sequence by transfer RNA (tRNA) on the ribosome. Modified nucleosides within RNA are involved in maintaining and regulating the protein synthesis.....»»
Bubbling with benefits: Hydrogen nanobubbles boost tomato antioxidants
Tomatoes are a key source of antioxidants, crucial for human health as they help combat oxidative stress. Traditional irrigation methods often fail to significantly enhance these beneficial compounds in crops. Hydrogen, known for its unique antioxida.....»»
Scientists replicate enzyme that captures carbon
Scientists from King's College London have recreated the active site of Acetyl-CoA Synthase, an enzyme involved in capturing carbon from the atmosphere. The research, carried out in collaboration with Imperial College London, advances our understandi.....»»
Enzyme-powered "snot bots" help deliver drugs in sticky situations
Snot might not be the first place you'd expect nanobots to be swimming around. But this slimy secretion exists in more places than just your nose and piles of dirty tissues—it also lines and helps protect the lungs, stomach, intestines and eyes. An.....»»
Defect engineering leads to designer catalyst for production of green hydrogen
Efficient technology for splitting the hydrogen–oxygen bond in water could be the key to producing low-cost, green hydrogen for energy storage at an industrial scale. Green hydrogen is expected to play a significant role in achieving the U.S. Depar.....»»
Solar energy-driven H₂O₂ photosynthesis from water and oxygen using Ba-implanted ordered carbon nitride
H2O2, a green oxidant and clean fuel, is in high demand across chemical industries, environmental treatments, and even aerospace. However, traditional production methods rely on energy-intensive processes that are not environmentally friendly. Scient.....»»
With Falcon 9 grounded, SpaceX test-fires booster for next Starship flight
SpaceX says a liquid oxygen leak caused the failure of a Falcon 9 launch last week. Enlarge / A drone shot looking down on SpaceX's Super Heavy booster during a test-firing of its 33 Raptor engines Monday. (credit: SpaceX).....»»
Nano-confinement may be key to improving hydrogen production
Researchers at Lawrence Livermore National Laboratory (LLNL) have discovered a new mechanism that can boost the efficiency of hydrogen production through water splitting......»»
Researchers directly simulate the fusion of oxygen and carbon nuclei
The fusion of two nuclei is a complex process influenced by many factors. These factors include not only the relative energy and angular momentum of the two nuclei, but also how their structures evolve as they collide. The outcome of the collisions i.....»»
Producing hydrogen and fertilizer at the same time
A research team from the University Alliance Ruhr, Germany, has found a catalyst that can be used to convert ammonia into the energy carrier hydrogen and the fertilizer precursor nitrite. The production of hydrogen and the production of fertilizer ha.....»»
Loss of oxygen in bodies of water identified as new tipping point
Oxygen concentrations in our planet's waters are decreasing rapidly and dramatically—from ponds to the ocean. The progressive loss of oxygen threatens not only ecosystems, but also the livelihoods of large sectors of society and the entire planet,.....»»
Atomically controlled MXenes enable cost-effective green hydrogen production
A total of 137 countries around the world have signed a "net-zero" climate change agreement to end fossil fuel use and achieve zero carbon emissions by 2050. Hydrogen is being touted as the next green energy source because it emits only water and oxy.....»»
Study introduces lead-coated nickel catalyst for enhanced hydrogen evolution reaction efficiency
In a recent collaboration, a research team developed a hydrogen evolution reaction catalyst that minimizes degradation caused by reverse current in alkaline water electrolysis systems......»»
Research team models connection between enzyme activity and yields for the first time
A team from the University of Illinois has developed a modeling framework connecting enzyme activity related to photosynthesis to yield. This is the first time a model has tied the dynamic photosynthetic pathways directly to crop growth......»»
Oxygen tweaking may be key to accelerator optimization
Particle accelerators are pricey, but their cost comes with good reason: These one-of-a-kind, state-of-the-art machines are intricately designed and constructed to help us solve mysteries about what makes up our universe. Still, the scientists and en.....»»
Scientists develop novel model and dataset for ocean dissolved oxygen monitoring
Chinese scientists have recently developed a novel method for measuring dissolved oxygen (DO) levels in the ocean and a new dataset for monitoring dissolved oxygen concentration (DOC) of global oceans......»»
Phage-derived enzyme targets E. faecalis biofilms to mitigate acute graft-versus-host disease
Allogenic hematopoietic cell transplantation (allo-HCT) involves transferring healthy donor stem cells to recipients with conditions such as blood cancer, bone marrow failure, or certain genetic blood disorders. Acute graft-versus-host disease (aGVHD.....»»
