The Defense Innovation Board within the Department of Defense (DoD) released a set of five ethics principles for the agency to consider when developing and using artificially intelligent systems in combat and non-combat settings. According to the board, such systems should be responsible, equitable, traceable, reliable, and governable. The board also provided twelve recommendations for DoD to best implement these ethics principles.

EPA has broadened a proposed rule, first proposed in April 2018, that requires that the agency whenever possible rely on studies for which all underlying data and models are publicly available to promulgate "significant regulatory decisions"; the rule would further assign lower weight to the evidence, findings, and conclusions of any studies that are based on confidential information that cannot be publicly disclosed. Whereas the original draft was limited to dose response data and dose response models, the new proposal is applicable to all data and models.

From 1940 to about 1975, the average global surface temperature decreased by about 0.1 degrees Celsius, interrupting a decades-long warming trend even as carbon emissions continued to rise. Many scientists thought the cooling trend was possibly caused by sulfate particles from the burning of fossil fuels that can scatter sunlight and reduce atmospheric warming.

Gamma-ray bursts are the most powerful explosions in the cosmos. These explosive events last a fraction of a second to several minutes and emit the same amount of gamma rays as all the stars in the universe combined. Such extreme amounts of energy can only be released during catastrophic events like the death of a very massive star, or the merging of two compact stars, and are accompanied by an afterglow of light over a broad range of energies that fades with time. Researchers have observed a gamma-ray burst with an afterglow that featured the highest energy photons—a trillion times more energetic than visible light—ever detected in a burst.
