An international team of astronomers has detected a new luminous quasar at a redshift of 7.02. The newly found quasi-stellar object (QSO), designated DELS J003836.10–152723.6, is the most luminous quasar known at a redshift of over 7.0. The discovery is reported in a paper published October 29 on the arXiv pre-print repository.
Powered by the most massive black holes, bright quasars at high redshift are important for astronomers as they are perceived as the brightest beacons highlighting the chemical evolution of the universe most effectively. They are the most luminous and most distant, compact objects in the observable universe and their spectrum can be used, for instance, to estimate the mass of supermassive black holes (SMBHs).
However, high-redshift QSOs are extremely rare and difficult to find. So far, only two quasars with redshifts over 7.0 have been identified. This limits our understanding of SMBH growth mechanism and reionization history.

On Wednesday, November 7, NASA will launch its Ionospheric Connection Explorer (ICON) spacecraft to study the ionosphere. This boundary lies between space and Earth, being home to a “sea” of charged electrons and ions; it reacts to both lower atmosphere weather and solar energy, the result being space weather. NASA’s ICON will study this, offering unprecedented scientific data.

A venture under pressure

“The problems the Bay Area is facing are the problems of success,” says Grant. The northern California metropolis is among the top 50 science cities in the Nature Index, measured by its contribution to the authorship of 82 high-quality research journals. When assessed solely on the output of its corporate institutions, it ranks number one. The question is whether the Bay Area can, in the face of mounting social problems, retain these companies and the brilliant researchers whose work they depend on.
Scientific innovation has long powered the San Francisco Bay Area’s economy, but community and political challenges could undermine progress.

Scientists in Japan have developed the world’s first test that can detect cancers in patient urine samples. The breakthrough technology by Japanese researchers from engineering firm Hitachi has been in development for two years and it may be made available by 2020.
According to Agence France-Presse, the research team will work with Nagoya University to analyze 250 urine samples to check for breast, colon, and childhood forms of the disease in central Japan. The experiments will begin this month and end in September.
