Protecting biocatalysts from oxygen
Certain enzymes from bacteria and algae can produce molecular hydrogen from protons and electrons—an energy carrier on which many hopes are riding. All they need for this purpose is light energy. The major obstacle to their use is that they are des.....»»
Sea level changes shaped early life on Earth, fossils show
A newly developed timeline of early animal fossils reveals a link between sea levels, changes in marine oxygen, and the appearance of the earliest ancestors of present-day animals......»»
Getting to the root of a plant"s success
Plants are powerful factories—they can turn basic ingredients like carbon dioxide, water, and sunlight into oxygen, sugars, and plant mass. But plants don't do all of this work on their own......»»
New perspectives for using corals in climate research
Ancient ocean temperatures are most commonly reconstructed by analyzing the ratio of different oxygen atoms in the calcium carbonate remains of fossils. However, this presents many challenges, including a combination of biological processes known as.....»»
Apple introduces revolutionary privacy technique for protecting sensitive data
Apple is finally introducing homomorphic encryption into its products. This cryptographic technique is new for the tech giant but will be a massive revolution for … The post Apple introduces revolutionary privacy technique for protecting sensit.....»»
How bacteria attach their cloaks of invisibility to immune defenses
Bacteria have different strategies for protecting themselves. Some bacterial pathogens surround themselves with a shell made of many sugar chains that lie close together, also known as capsular polymers. This protects the bacteria from drying out and.....»»
Study offers hope for development of vaccine capable of protecting cattle against malignant catarrhal fever
A research team led by University of Liège scientists has published a groundbreaking study on malignant catarrhal fever (MCF). This disease is caused by the alcelaphine gammaherpesvirus 1 (AlHV-1), which infects its natural host, the wildebeest......»»
Protecting your pig from diamond skin disease
Everybody wants to find a diamond in the rough, but no one wants their pig to develop diamond skin disease—an infection that can cause pain and discomfort and may lead to death if left untreated......»»
The Mysterious Discovery of ‘Dark Oxygen’ on the Ocean Floor
Researchers believe they have discovered oxygen being produced 4,000 meters below the sea surface, and think polymetallic nodules—the sought-after bounty of deep-sea miners—could be the source......»»

A study published in Cell Reports Physical Science showcases a novel method for the recycling of unsaturated polymers such as rubber and plastics......»»
Seasonal menace: Protecting livestock against external parasites
While rain followed by sunshine produces the eye-catching sight of a rainbow, it can also mark the need for livestock owners to confront the insects and parasites that thrive in the summer season......»»
Study reveals key gene protecting plants from harmful metals in soil
The negative impact of human activity on Earth doesn't just affect our planet's atmosphere—it goes much deeper, into its soils. For instance, excessive application of manure or sewage sludge can increase heavy metal concentrations in agricultural l.....»»
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.....»»
Protecting one of the world"s most threatened marine animals
Researchers from Murdoch University's Harry Butler Institute have employed the latest genetic techniques to uncover critical breeding and reproductive knowledge about one of the world's most threatened marine animals—the sawfish......»»
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
