Phys.org / Atoms passing through walls: Quantum tunneling of hydrogen within palladium crystal
At low temperatures, hydrogen atoms move less like particles and more like waves. This characteristic enables quantum tunneling, the passage of an atom through a barrier with a higher potential energy than the energy of the ...
Phys.org / Laser-induced break-up of C₆₀ fullerenes caught in real-time on X-ray camera
The understanding of complex many-body dynamics in laser-driven polyatomic molecules is crucial for any attempt to steer chemical reactions by means of intense light fields. Ultrashort and intense X-ray pulses from accelerator-based ...
Phys.org / New membrane sets record for separating hydrogen from CO₂
When designing membranes that separate industrial gases, scientists often incorporate structures that attract the gas they want to obtain. This attraction can enhance the membrane's permeability, and help isolate the desired ...
Phys.org / Unlocking the genome's hidden half with new DNA sequencing technology
Cornell researchers have found that a new DNA sequencing technology can be used to study how transposons move within and bind to the genome. Transposons play critical roles in immune response, neurological function and genetic ...
Phys.org / Biodegradable mulching film can protect plants without pesticides or plastics
Whether you're a home gardener or an industrial farmer, you might be familiar with mulching films—plastic sheets laid over the soil to protect seedlings and promote crop growth. But like many other plastic materials, these ...
Phys.org / What would a small black hole do to the human body? Scientist aims to answer that
Some people may worry about being bitten by a snake or spider, but have you ever considered what would happen if a small black hole tried to pass through your body?
Phys.org / Male green hermit hummingbirds: Bills evolved for battle
Let's get one thing out of the way: All hummingbirds fight. Most species fight for food, using their tiny bodies and sharp bills to force competitors away from flowers. But the green hermit hummingbird, which lives primarily ...
Phys.org / Mercury pollution in marine mammals is increasing, new study finds
In 2017, a new global treaty was meant to bring mercury pollution under control. But three decades of data from UK harbor porpoises show mercury is still increasing, and is linked to a higher risk of dying from infectious ...
Phys.org / Understanding intrinsically disordered protein regions and their roles in cancer
Every function in a cell is associated with a particular protein or group of proteins, typically in a well-defined three-dimensional structure. However, intrinsically disordered regions of proteins defy this structure-function ...
Phys.org / Artificial cartilage mimics natural flexibility with adjustable structure
A Washington State University research team is working to create an artificial cartilage that is similar to natural cartilage with a recipe that can be corrected along the way.
Phys.org / Synthesizing stable, open-chain amines with nitrogen-based chirality
A research team from Prof. Benjamin List's department at the Max Planck Institut für Kohlenforschung has solved a long-elusive riddle of chemistry: the synthesis of stable, open-chain amines that carry their chirality on ...
Phys.org / Symmetry simplifies quantum noise analysis, paving way for better error correction
Researchers from the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, and Johns Hopkins University in Baltimore have achieved a breakthrough in quantum noise characterization in quantum systems—a key ...
