Researchers have detailed the physics behind a phenomenon that allows them to create spin in liquid droplets using ultrasound waves, which concentrates solid particles suspended in the liquid. The discovery will allow researchers to engineer technologies that make use of the technique to develop applications in fields such as biomedical testing and drug development.

A new camera setup can record three-dimensional movies with a single pixel. Moreover, the technique can obtain images outside the visible spectrum and even through tissues. The development thus opens the door to holographic video microscopy.

Astronomers have witnessed for the first time a violent cosmic collision in which one galaxy pierces another with intense radiation. Their results show that this radiation dampens the wounded galaxy’s ability to form new stars.

Increasing renewable energy may not reduce the use of fossil fuels in the United States, according to a new study .

Astronomers have filled a large gap in knowledge about Mars’ water cycle. Their research on water percolating from surface to aquifer could change the picture of what early Mars was like, suggesting that less of the planet’s water may have been available to become rain and refill lakes and oceans.

Scientists have made a breakthrough in eco-friendly batteries that not only store more energy but could also help tackle greenhouse gas emissions. Lithium-CO2 ‘breathing’ batteries release power while capturing carbon dioxide, offering a greener alternative that may one day outperform today’s lithium-ion batteries.

The orbital angular momentum of electrons has long been considered a minor physical phenomenon, suppressed in most crystals and largely overlooked. Scientists have now discovered that in certain materials it is not only preserved but can even be actively controlled. This is due to a property of the crystal structure called chirality, which also influences

A team of researchers studied the properties of membranes to understand how these cellular structures influenced the chemistry of life on Earth as it began.

Researchers demonstrated a way to to manipulate electrons using pulses of light that last less than a trillionth of a second to record electrons bypassing a physical barrier almost instantaneously — a feat that redefines the potential limits of computer processing power.

The average energy project costs 40% more than expected for construction and takes almost two years longer than planned, finds a new global study. One key insight: The investment risk is highest for nuclear power plant construction and lowest for solar. The researchers analyzed data from 662 energy projects built between 1936 and 2024 in
