Rockwell Collins to provide engineering, technical data for E-2D Hawkeye

Business
Aug. 31 (UPI) -- Rockwell Collins Simulation and Training Solutions has received a $ 32.9 million contract modification to provide for engineering and technical data services for the E-2D Hawkeye Integrated Training Systems engineering change proposal. The contract modification, announced Thursday by the Department of Defense, also provides for the production of one Simulated Maintenance Trainer Device, upgraded power plant trainers and personal computer simulators for aircraft training. Work on the contract will be performed in Norfolk, Va., and is expected to be completed in September 2020. Navy 2017 and 2018 aircraft procurement funds in the full amount of the contract have been obligated at the time of award. The E-2D Advanced Hawkeye is the latest variant of the Navy's carrier-based ...
Sea squirts provide insights into gut defense evolution

Sea squirts provide insights into gut defense evolution

Science
Aug. 23 (UPI) -- In the guts of vertebrates, a thin layer of mucous protects the rest of the body from harmful bacteria. Most invertebrates have an intestinal membrane composed of chitin. Both strategies guard against infection, but scientists have struggled to determine which mechanism evolved first and how they relate to each other. For clues, researchers looked to tunicates, a group of filter-feeding marine invertebrates. Tunicates, like sea squirts, deploy both a layer of chitin and mucous. "We noticed that tunicates seemed to have an intermediate kind of gut lining that could show that mammalian and invertebrate gut linings shared an evolutionary link," Keisuke Nakashima, marine biologist at the Okinawa Institute of Science, said in a news release. A survey of intestinal defense str...
Seagrass can provide localized protection against ocean acidification

Seagrass can provide localized protection against ocean acidification

Science
July 31 (UPI) -- Seagrass could serve as a local buffer against ocean acidification, protecting vulnerable species against rising levels of carbonic acid. In addition to providing food and shelter to a variety of marine organisms, seagrass also absorbs carbon dioxide as it performs photosynthesis. Researchers with the Carnegie Institution for Science designed to models to measure whether a seagrass meadow's carbon uptake abilities could lower pH levels. The models accounted for grass density, photosynthetic activity, water depth, currents and a variety of other factors. The results, detailed in the journal Ecological Applications, suggests seagrass can have a small, local effect on ocean acidity. "Local stakeholders, such as California's shellfish industry, want to know whether seagrass m...

South Korea pondering whether to provide North Korea oil for cultural event

World
SEOUL, South Korea, Jan. 27 (UPI) -- South Korea may decide to ship refined petroleum to North Korea to power an inter-Korean cultural event next week.A South Korean government official said Sunday that Seoul is currently considering the move as "the North's oil supplies aren't in good condition" but there has been criticism "this would go against the flow of international sanctions on Pyongyang."The inter-Korean event on Feb. 4 will likely take place at a cultural center in North Korea's Mt. Kumang region. The facility, which was built by a South Korean firm, runs on a diesel-fueled generator.South Korea had asked the North to provide the power to hold the concert, according to the government official.However, the North responded that it would be difficult as it faces an oil supply shorta...
