Multi-domain operations, the Army's future operating concept, requires autonomous agents with learning components to operate alongside the warfighter. New Army research reduces the unpredictability of current training reinforcement learning policies so that they are more practically applicable to physical systems, especially ground robots.

In the far north, the swelling Arctic Ocean inundated vast swaths of coastal tundra and steppe ecosystems. Though the ocean water was only a few degrees above freezing, it started to thaw the permafrost beneath it, exposing billions of tons of organic matter to microbial breakdown. The decomposing organic matter began producing CO2 and CH4, two of the most important greenhouse gases.

Since CO2 has been recognized as the most important anthropogenic greenhouse gas owing to its significant impact on global warming and climate change, there have been a substantial number of studies that have focused on investigating the status of CO2 in the atmosphere in the past and present, and how it will change in the future.

A fast, green and one-step method for producing porous carbon spheres, which are a vital component for carbon capture technology and for new ways of storing renewable energy, has been developed by Swansea University researchers.
The method produces spheres that have good capacity for carbon capture, and it works effectively at a large scale.

WASHINGTON — The White House released a national strategy for planetary protection Dec. 30, outlining new assessments to prevent terrestrial contamination of other worlds and vice versa.
The National Strategy for Planetary Protection, developed by an interagency working group led by the National Space Council and Office of Science and Technology Policy (OSTP), outlines work to be done over the next year to update planetary protection policies, considering both scientific advances as well as growing private capabilities in space exploration.
