Q-band Line Survey Observations Toward A Carbon-chain-rich Clump In The Serpens South Region
We have conducted Q-band (30 GHz − 50 GHz) line survey observations toward a carbon-chain emission peak in the Serpens South cluster-forming region with the extended Q-band (eQ) receiver installed […]

The Human Genome Has Been Stored On An Everlasting Memory Crystal
University of Southampton scientists have stored the full human genome on a 5D memory crystal – a revolutionary data storage format that can survive for billions of years. The team […]

On Interstellar Quantum Communication And The Fermi Paradox
Since it began Cocconi Morrison, the search for extraterrestrial intelligence (SETI) has focused on interstellar classical communication. Recently, Berera:2020rpl pointed out that, at certain frequencies, photon qubits can retain their […]
