Comet inspires chemistry for making breathable oxygen on Mars

Researchers have demonstrated a new reaction for generating oxygen that could help humans explore the universe and perhaps even fight climate change at home.

Researchers crack an enduring physics enigma

For decades, physicists, engineers and mathematicians have failed to explain a remarkable phenomenon in fluid mechanics: the natural tendency of turbulence in fluids to move from disordered chaos to perfectly parallel patterns of oblique turbulent bands. This transition from a state of chaotic turbulence to a highly structured pattern was observed by many scientists, but never understood.

Researcher discusses reopening the case of cold fusion

Researchers at MIT have collaborated with a team of scientists from the University of British Columbia, the University of Maryland, Lawrence Berkeley National Laboratory, and Google to conduct a multiyear investigation into cold fusion, a type of benign nuclear reaction hypothesized to occur in benchtop apparatus at room temperature.

Subcritical experiment captures scientific measurements to advance stockpile safety

Lawrence Livermore National Laboratory (LLNL) successfully executed its first subcritical experiment since 2003 on Feb. 13 at the Nevada National Security Site (NNSS) U1a facility. The experiment—dubbed "Ediza"—took place deep below the desert floor and was the culmination of a five-year campaign aimed at capturing high-fidelity plutonium data in support of nuclear stockpile safety.

Scientists revisit the cold case of cold fusion

Scientists from the University of British Columbia (UBC), the Massachusetts Institute of Technology, the University of Maryland, the Lawrence Berkeley National Laboratory, and Google are conducting a multi-year investigation into cold fusion, a type of benign nuclear reaction hypothesized to occur in benchtop apparatus at room temperature.

Ultra-cold lithium atoms shed light on pair formation in superfluids, helping identify best theories

A FLEET/Swinburne study released this week resolves a long-standing debate about what happens at the microscopic level when matter transitions into a superconducting or superfluid state.

Colliding lasers double the energy of proton beams

Researchers have developed a new method which can double the energy of a proton beam produced by laser-based particle accelerators. The breakthrough could lead to more compact, cheaper equipment that could be useful for many applications, including proton therapy.

Direct measurement of the cosmic-ray proton spectrum with the CALET on the ISS

Recent advances in the observation of high-energy radiations, including X-rays and gamma-rays, have unveiled many high-energy aspects of the universe. To achieve a complete understanding of these radiations, however, researchers need to find out more about the high-energy particles (i.e. cosmic rays) that produce them. In fact, non-thermal radiations characterized by the power-law spectrum are all backed by the acceleration and propagation of these rays.

New discovery about terahertz radiation behefits biomedicine

Scientists from ITMO University for the first time in the world managed to directly measure the nonlinear refractive index of matter in the terahertz range. The results of the experiments were compared with previous theoretical predictions to confirm the presence of nonlinear effects. The obtained data can be used to control light, as well as in fundamental and biomedical research. The results are published in Optics Express.

Colliding lasers double the energy of proton beams

Researchers from Sweden's Chalmers University of Technology and the University of Gothenburg present a new method which can double the energy of a proton beam produced by laser-based particle accelerators. The breakthrough could lead to more compact, cheaper equipment that could be useful for many applications, including proton therapy.
