New experiments using one-dimensional gases of ultra-cold atoms reveal a universality in how quantum systems composed of many particles change over time following a large influx of energy that throws the system out of equilibrium.

The connection between quantum physics and the theory of relativity is extremely hard to study. But now, scientists have set up a model system, which can help: Quantum particles can be tuned in such a way that the results can be translated into information about other systems, which are much harder to observe. This kind of 'quantum simulator' works very well and can lead to new insights about the nature of relativity and quantum physics.

Soon, you'll be able to get a box of freshly picked, sweet strawberries from the grocery store or local farm stand. But it's disappointing when you get them home and find that the ones at the bottom have started to rot. To increase the berries' shelf life, researchers have incorporated cannabidiol -- a non-hallucinogenic compound from cannabis known as CBD -- and sodium alginate into an edible antimicrobial coating.

Up to two-thirds of the soot above the central Amazon rainforest originates in Africa. Researchers differentiate soot particles using their relative properties and attribute them to their respective points of origin. They found that bush fires and burning savannah in the north and south of Africa make a substantial contribution to air pollution in the central Amazon all year round, thereby playing an important role in the earth radiation budget and water cycle. This is caused by the efficient transatlantic transport of particles through the atmosphere.

Chemists have taken a big step toward splitting hydrogen and oxygen molecules to make pure hydrogen -- without using fossil fuels. Results from pulse radiolysis experiments have laid bare the complete reaction mechanism for an important group of 'water-splitting' catalysts. The work means scientists are closer to making pure hydrogen from renewable energy, an energy source that could contribute to a greener future for the nation and world.

Researchers are embarking on a groundbreaking project to mimic the natural process of photosynthesis using bacteria to deliver electrons to a nanocrystal semiconductor photocatalyst. By leveraging the unique properties of microorganisms and nanomaterials, the system has the potential to replace current approaches that derive hydrogen from fossil fuels, revolutionizing the way hydrogen fuel is produced and unlocking a powerful source of renewable energy.
