Could artificial intelligence improve the accuracy of screening for breast cancer? A comparison of the diagnostic performance of expert physicians and computers suggests so, but the clinical implications are as yet uncertain.
Observations of a distant cluster of galaxies suggest that star formation began there only 370 million years after the Big Bang. The results provide key details about where and when the first stars and galaxies emerged in the Universe.
The redshift of a seemingly mature galaxy cluster has been confirmed spectroscopically to be about 2 and photometry indicates that star formation began in the galaxies of the cluster at a redshift of about 12.
A widely used vaccine against tuberculosis has now been shown to provide almost complete protection when injected intravenously. This is a striking improvement over vaccination through the typical intradermal route.
The reliance of infrared spectroscopy on light transmission limits the sensitivity of many analytical applications. An approach that depends on the emission of infrared radiation from molecules promises to solve this problem.
Systematic methods for evaluating progress towards the 17 United Nations Sustainable Development Goals are developed and tested using 119 indicators at China’s national and subnational levels during 2000–2015, showing improvement overall.
An artificial intelligence (AI) system performs as well as or better than radiologists at detecting breast cancer from mammograms, and using a combination of AI and human inputs could help to improve screening efficiency.
The labyrinthine domain patterns formed in ultrathin films of ferroelectric oxides by subcritical quenching undergo an inverse phase transition to the less-symmetric parallel-stripe domain structure upon increasing temperature.
An analysis based on Landsat imagery shows that the extent of river ice has declined extensively over past decades and that this trend will continue under future global warming.
The delivery route and dose of the BCG vaccine profoundly alters the protective outcome after Mycobacterium tuberculosis challenge in non-human primates.
