Phys.org / Measuring titanium in Apollo rock to uncover moon's early chemistry
Earth and the moon may look very different today, but they formed under similar conditions in space. In fact, a dominant hypothesis says that the early Earth was hit by a Mars-sized object, and it was this giant impact that ...
Phys.org / Finding the 'quantum needle' in a haystack: New filtering method can isolate photons
In quantum technologies, everything depends on the ability to detect the properties carried by a single photon. But in the real world, that photon of interest is often buried in a sea of unwanted light—a true "needle in a ...
Phys.org / Tropical volcanic eruptions trigger atmospheric changes that drive droughts in Asia
Volcanoes are both captivating and disastrous. Most are likely familiar with the common short-term dangers associated with them: explosive forces, lava, and even atmospheric particles disrupting air traffic. But researchers ...
Phys.org / Soil bacteria break down toxic chemicals in the environment
Many aromatic compounds, such as phenols, cresols and styrenes, are toxic to organisms and harmful to the environment. They can accumulate as a result of industrial processes and harm ecosystems. Soil bacteria can help to ...
Phys.org / Limits of protein evolution could reshape ideas about early life
The number of known proteins is infinitely small in comparison to the universe of possible proteins, which could in theory be realized. Yet these known proteins are the only major training ground for future protein design. ...
Phys.org / Cells under stress: How a chemotherapy drug damages RNA
The integrity of DNA and RNA is essential for every cell. DNA contains the genetic information for proteins, while RNA serves as a working copy of individual genes and is required for the synthesis of proteins. Unlike DNA ...
Phys.org / Copper-loaded starch nanoparticles can target bacteria in microbial communities
Bacteria are a major cause of infections and death in hospital settings, due—in part—to the rising incidence of antibiotic resistance. In the United States, antibiotic-resistant bacteria are involved in more than 2 million ...
Phys.org / Location matters: How one fat molecule can help trigger both cell limbo and cell death
When cells experience enough chronic stress, they can stop dividing permanently. In this state of cellular limbo, known as replicative senescence, cells remain alive but no longer proliferate. Pinpointing the stressors that ...
Phys.org / No dyes, less cell stress: How mid-infrared ultrasound imaging tracks lipids live
A team at Helmholtz Munich and the Technical University of Munich (TUM) has developed a new microscopy technique that can distinguish lipid species in living cells—in particular cholesterol and sphingomyelin—and map them ...
Phys.org / A universal scheme can verify any quantum state
Quantum technologies, devices that can process, store, or detect information leveraging quantum mechanical effects, could outperform classical devices in some tasks or scenarios. Despite their potential, verifying that these ...
Phys.org / Embryo-like fossils from Southern China offer new clues about ancient life
Some of the most ancient fossils collected to date were traced back to the Ediacaran period. This is the time interval ranging from around 635 to 541 million years ago, shortly before the time when scientists predict that ...
Phys.org / Novel protocol reconstructs quantum states in large-scale experiments up to 96 qubits
Quantum computers, systems that process information leveraging quantum mechanical effects, could outperform classical computers on some computationally demanding tasks. Despite their potential, as the size of quantum computers ...
