Tech Xplore / Phase-changing VO₂ turns methane into propane and hydrogen more efficiently
Converting methane, the primary component of natural gas, into higher alkanes and hydrogen, could be highly advantageous. Alkanes, such as propane and butane, are easier to transport than methane and are used in a wider range ...
Medical Xpress / Beyond rating scales: AI brings natural language to depression screening, improving accuracy and user experience
For over a century, standardized rating scales have been the dominant method of psychological assessment, but they often limit how people express complex or nuanced mental states. A new study introduces an approach that combines ...
Phys.org / In Arizona's desert, tiny ants turn into living hygienists, climbing inside bigger ants' mandibles and cleaning them
Ants are known for many things. They fight, bite and sometimes compete for every crumb. We can now possibly add cleaning services to that list, according to a study published in the journal Ecology and Evolution.
Phys.org / Scottish Neolithic tombs were used to trace kinship—including descent, DNA analysis reveals
Archaeologists have investigated genetic relationships between individuals buried in Neolithic chambered tombs in northern Scotland, suggesting monumental tombs may have been physical embodiments of prehistoric kinship, tracing ...
Phys.org / Predictably unpredictable: Building resilient crops for a changing world
An unusually mild winter followed by a wet spring made last year one of the worst in a decade for Pennsylvania soybean growers. It wasn't the soybeans that were the problem; it was the slugs. The pests survived the warm winter ...
Phys.org / Protein clusters reshape cell movement and may help cells build amino acids faster
Cells can be thought of as cities, with factories, a transport system, and lots of building activity. An international team led by scientists at the University of Groningen studied cells growing under different conditions ...
Phys.org / Physicists discover how to reverse 'quantum scrambling'
Quantum computers stand to revolutionize research by helping investigators solve certain problems exponentially faster than with conventional computers. Current quantum computers encounter a challenge where they lose stored ...
Phys.org / Satellites reveal city methane emissions are rising faster than official estimates
Urban emissions of methane—a potent greenhouse gas—are rising faster than bottom-up accounting estimates anticipated, according to a study led by University of Michigan Engineering. The discrepancy was found with satellite ...
Phys.org / Video shows that sunbirds suck, while hummingbirds don't
Two unrelated groups of nectar eaters, hummingbirds and sunbirds, have evolved different techniques to slurp the sweet liquid from flowers. The tongue suctioning employed by sunbirds is unique among vertebrates, according ...
Phys.org / Quantum sensors get a precision boost as 2D defects reveal their hidden timing
A key factor for the performance of sensors is the speed at which the system returns to its initial state after a disturbance or measurement, similar to the taring of a balance. In the quantum sensor under investigation, ...
Phys.org / From ship wakes to soft tissues: Exploring fluid and solid surface-wave physics
A new study by scientists in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) shows that when a pressure disturbance moves across an ultrasoft elastic material, such as a gel or a biological tissue, ...
Phys.org / Powerful imaging pulls lost ocean life from 445-million-year-old stone and exposes a hidden extinction record
New technology has helped a team of scientists uncover more than 20 microscopic fossils, including a species previously unknown to science. The discovery may provide us with fresh insights into the Late Ordovician, one of ...
