Researchers model the motions of groups of manta rays to study how group dynamics affect their propulsion, studying different formations of three manta rays: in tandem, in a triangular setup with one manta ray in front leading two behind, and in an inverse triangular configuration with one manta ray trailing the other two. They found the tandem formation only significantly increases propulsion for the middle manta ray, and the two triangular setups result in overall decreased efficiency compared to a single swimmer on its own. These findings can help optimize formations for underwater vehicle operations.

Note: Other Biofuels includes sustainable aviation fuel (SAF), renewable heating oil, renewable naphtha, renewable propane, renewable gasoline, and other emerging biofuels that are in various stages of development and commercialization. SAF production capacity is an estimate based on company announcements and trade press and only includes hydroprocessed esters and fatty acids (HEFA) SAF. We do not publish SAF production capacity data.
Sustainable aviation fuel (SAF) production is growing in the United States as new capacity comes online. U.S. production of Other Biofuels, the category we use to capture SAF in our Petroleum Supply Monthly, approximately doubled from December 2024 to February 2025.
SAF is an alternative to petroleum jet fuel. It’s produced from agricultural and waste feedstocks

FRANKFORT, Ky. — Kentucky farmers and ranch hands whose tools or equipment were damaged by the February or April severe storms, straight-line winds, tornadoes, landslides and mudslides may be eligible for disaster assistance. FEMA assistance is available to replace disaster-damaged essential tools, supplies, equipment and items required for employment or for self-employment.
Coverage for Tools and Equipment
Family-owned farms typically have a variety of equipment needed to conduct business. These include, but are not limited to, tractors, plows, seeders or planters, harvesters, sprayers, hay balers and utility vehicles. These items are all potentially eligible for FEMA disaster assistance if the applicant can show that they were damaged by the disaster, the applicant does not have another working item that can meet this need, and the loss of the item was not covered by insurance. Crops and livestock are not “tools and equipment” because they are the products of a farming operation, whereas tools and equipment are the means of production.
Ranch hands may be eligible for assistance to replace disaster-damaged tools and equipment not covered by insurance when they can show these items are required by their employer.
Assistance is based on a need to replace disaster-damaged essential tools, supplies, equipment, items required by an employer as a condition of employment or required for education. This includes disaster-damaged tools and equipment, or other items required for
