Researchers show that precisely layering nano-thin materials creates excitons — essentially, artificial atoms — that can act as quantum information bits, or qubits.

A combination of cosmic processes shapes the formation of one of the most common types of planets outside of our solar system, according to a new study.

New modeling indicates the main belt asteroid (52246) Donaldjohanson may have formed about 150 million years ago when a larger parent asteroid broke apart; its orbit and spin properties have undergone significant evolution since. When NASA’s Lucy spacecraft flies by this approximately three-mile-wide space rock on April 20, 2025, the data collected could provide independent

With artificial photosynthesis, humankind could utilize solar energy to bind carbon dioxide and produce hydrogen. Chemists have taken this one step further: They have synthesized a stack of dyes that comes very close to the photosynthetic apparatus of plants. It absorbs light energy, uses it to separate charge carriers and transfers them quickly and efficiently

Researchers have experimentally recreated another fundamental theoretical model from quantum physics, which goes back to the Nobel Prize laureate Werner Heisenberg. The basis for the successful experiment is made of tiny carbon molecules known as nanographenes. This synthetic bottom-up approach enables versatile experimental research into quantum technologies, which could one day help drive breakthroughs in

Iridium-doped iron-cobalt (Fe-Co-Ir) alloys, previously identified through machine learning, have been shown to have enhanced magnetic properties, surpassing even the widely used pure Fe-Co alloy. However, the origin of this enhanced magnetization is poorly understood. Now, scientists employed an innovative method using high-throughput X-ray magnetic circular dichroism (XMCD) measurements, demonstrating the critical role of Ir-doping.

Digital voice recordings contain valuable information that can indicate an individual’s cognitive health, offering a non-invasive and efficient method for assessment. Research has demonstrated that digital voice measures can detect early signs of cognitive decline by analyzing features such as speech rate, articulation, pitch variation and pauses, which may signal cognitive impairment when deviating from

Curiosity about a mistake that left tiny dots on a germanium wafer with evaporated metal films led to the discovery of beautiful spiral patterns etched on the surface of the semiconductor by a chemical reaction. Further experiments showed that the patterns arise from chemical reactions that are coupled to mechanical forces through the deformation of

Water once existed in abundance of at the surface of Mars. How much of that water has been stored in the planet’s crust is still unclear, according to a new analysis.

Scientists improved battery durability and energy density with a nano-spring coating.
