When an optical fiber is immersed in liquid, a high temperature, high speed jet is discharged. Researchers expect this to be applied to medical treatment in the future. Now, a research team from Russia and Japan has explored this phenomenon further and revealed the reasons behind the jet formation.

Researchers have shaken up a once accepted timeline for cataclysmic events in the early solar system. Geological and geochemical records indicate that the Earth-Moon system experienced a period of frequent and cataclysmic impacts from asteroids and other bodies. It was thought that this period had a relatively sudden onset, but the researchers have found evidence that this bombardment period may have started much earlier, and decreased in intensity over time.

The Laser Interferometer Gravitational-wave Observatory (LIGO) Scientific Collaboration and the Virgo Collaboration (Virgo) announce the detection of gravitational waves from the spectacular collision of two black holes with “forbidden” masses. This marks the first time an intermediate-mass black hole has been observed. Two papers about the event, known as GW190521 have been accepted for publication today in the journal Physical Review Letters and The Astrophysical Journal Letters. Professor Tjonnie Li and Professor Juan Calderon Bustillo of the Department of Physics at The Chinese University of Hong Kong (CUHK), lead the only group in Hong Kong involved with the work of LIGO, and have been deeply involved in the analysis of this signal.

The quantum chromodynamics (QCD) phase transition in core-collapse supernovae has been examined for the first time, using state-of-the-art multi-dimensional supernova simulations and unique imprints of such a phase transition on the emitted gravitational-wave and neutrino signals have been detected. The findings have been reported in a paper jointly authored by Professor Ming-chung Chu and Dr. Lap-Ming Lin from The Chinese University of Hong Kong (CUHK), Dr. Shuai Zha (CUHK PhD 2019) and Professor Evan O’Connor from Stockholm University, and Professor Sean M. Couch from Michigan State University. It was recently published and selected as Editors’ Suggestion in the Physical Review Letters, a top physics journal.

A new study reveals that asteroid impact sites in the ocean may possess a crucial link in explaining the formation of the essential molecules for life. The study discovered the emergence of amino acids that serve as the building blocks for proteins - demonstrating the role of meteorites in bringing life's molecules to Earth, and potentially Mars.

While InSight's seismometer has been patiently waiting for the next big marsquake to illuminate its interior and define its crust-mantle-core structure, two scientists, Takashi Yoshizaki and Bill McDonough have built a new compositional model for Mars. They used rocks from Mars and measurements from orbiting satellites to predict the depth to its core-mantle boundary, some 1,800 km beneath the surface and have been able to suggest that its core contains moderate amounts of sulfur, oxygen and hydrogen as light elements.

A new hydrous phase, ε-AlOOH, was observed to be stable at pressures above ~200 GPa. The stability of ε-AlOOH at extremely high pressures may affect the modelling results of the internal structure and deep water circulation of some extra-solar planets, such as terrestrial super-Earths, because the hydroxide may store water in these regions.
