Carbon-Hungry Microorganisms to Help Battle Climate Change
Scientists have demonstrated a new technique, modeled after a metabolic process found in some bacteria, for converting carbon dioxide (CO2) into liquid acetate, a key ingredient in “liquid sunlight” or solar fuels produced through artificial photosynthesis. New technique could fast-track future carbon-free solar fuels.

A Growing Threat: Deliberate, Simultaneous Release of Pandemic Viruses Across Travel Hubs
COVID-19 demonstrated how the world is clearly vulnerable to the introduction of a single pandemic virus with a comparatively low case fatality rate. The deliberate and simultaneous release of many pandemic viruses across travel hubs could threaten the stability of civilization. Current trends suggest that within a decade, tens of thousands of skilled individuals will be able to access the information required for them single-handedly to cause new pandemics.

Maintaining Mountain Snowpacks Essential for Preserving Valuable Freshwater Resource
Snowcapped mountains generate mountain water runoff and snowmelt, which flow down to streams, rivers, lakes, and oceans. Around a quarter of the world depends on these natural “water towers” to replenish downstream reservoirs and groundwater aquifers for urban water supplies, agricultural irrigation, and ecosystem support. Carbon mitigation strategies are needed to maintain snowpack throughout the Americas.

The Benefits of Integrating Electric Vehicles into Electricity Distribution Systems
As the cost of EVs continues to decrease, the industry matures, incentives grow, and charging infrastructure improves, EVs could make up the vast majority of vehicles on the road in 2050. Many studies have looked at how increased electricity demand will affect the bulk power system in the United States, but public analysis of the impacts on the distribution system has been less prevalent.

DHS S&T Baggage, Cargo, and People Screening (BCP) Program develops state-of-the-art screening solutions to help secure airspace, communities, and borders
Factories First: Winning the Drone War Before It Starts
Wars are won by factories before they are won on the battlefield,Martin C. Feldmann writes, noting that the United States lacks the manufacturing depth for the coming drone age. Rectifying this situation “will take far more than procurement tweaks,” Feldmann writes. “It demands a national-level, wartime-scale industrial mobilization.”
