Researchers have developed a new method for quickly detecting and identifying very low concentrations of gases. The new approach, called coherently controlled quartz-enhanced photoacoustic spectroscopy, could form the basis for highly sensitive real-time sensors for applications such as environmental monitoring, breath analysis and chemical process control.

“Most gases are present in small amounts, so detecting gases at low concentrations is important in a wide variety of industries and applications,” said research team leader Simon Angstenberger from the University of Stuttgart in Germany. “Unlike other trace gas detection methods that rely on photoacoustics, ours is not limited to specific gases and does not require prior knowledge of the gas that might be present.”

Quantum computers require extreme cooling to perform reliable calculations. One of the challenges preventing quantum computers from entering society is the difficulty of freezing the qubits to temperatures close to absolute zero.

Now, researchers at Chalmers University of Technology, Sweden, and the University of Maryland, U.S., have engineered a new type of refrigerator that can autonomously cool superconducting qubits to record low temperatures, paving the way for more reliable quantum computation.

Quantum computers have the potential to revolutionize fundamental technologies in various sectors of society, with applications in medicine, energy, encryption, AI, and logistics. While the building blocks of a classical computer—bits—can take a value of either 0 or 1, the most common building blocks in quantum computers—qubits—can have a value of 0 and 1 simultaneously.

Over 100 small earthquakes in Surrey might have been caused by oil drilling nearby, according to UCL research.

The study, which involved extensive simulations, points to a probable link between seismic activity and the pressures of oil extraction.

In October 2022, scientists detected the explosive death of a star 2.4 billion light-years away that was brighter than any ever recorded.

As the star’s core collapsed down into a black hole, the gamma-ray burst emitted by the star – an event named GRB 221009A – erupted with energies of up to 18 teraelectronvolts. Gamma-ray bursts are already the brightest explosions our Universe can produce; but GRB 221009A was an absolute record-smasher, earning it the moniker “the BOAT” – Brightest Of All Time.

There is, however, something wrong with the picture, according to a team of astrophysicists led by Giorgio Galanti of the National Institute for Astrophysics (INAF) in Italy. Based on cutting-edge models of the Universe, we shouldn’t be able to see photons more powerful than 10 teraelectronvolts in data from the Large High Altitude Air Shower Observatory (LHAASO) that made the detection.

NVIDIA today announced NVIDIA Cosmos™, a platform comprising state-of-the-art generative world foundation models, advanced tokenizers, guardrails and an accelerated video processing pipeline built to advance the development of physical AI systems such as autonomous vehicles (AVs) and robots.

Geophysicists at ETH Zurich are using models of the lower mantle to identify areas where earthquake waves behave differently than previously assumed. This indicates the presence of zones of rocks that are colder, or have a different composition, than the surrounding rocks. This finding challenges our current understanding of the Earth’s plate tectonics – and presents the researchers with a major mystery.
