The US government has awarded a $11.3 million contract to Summa Technology Inc. for the manufacture, operation, and maintenance of Fastrac rocket engines. The company will build three new flight engines for the X-34 technology demonstrator and utilize one existing engine.
A new University of North Carolina at Chapel Hill study finds that child abuse homicides are more common than vital records reveal, with over 9,400 US children under 11 dying from abuse between 1985 and 1996. The true number is estimated to be three times higher than reported cases.
Researchers at UT Southwestern Medical Center have converted dendritic cells into cells that deliver death signals, potentially preventing and treating inflammatory diseases. This technology could lead to the prevention and treatment of inflammatory diseases such as rheumatoid arthritis.
The Second Annual International Autonomous Underwater Vehicle (AUV) Competition will take place at the Naval Systems Warfare Center in Panama City, Florida. Six university teams will compete for a $10,000 prize, with a focus on developing capable AUVs and top-notch engineers to work on them.
Researchers found that women with high HIV RNA levels in their blood transmitted the virus to their infants more often than those with low levels, highlighting the importance of treatment strategies aimed at reducing viral load. The studies also suggest that undetectable viral RNA levels can significantly reduce transmission risk.
Researchers found that cinnamon is lethal to E. coli O157:H7 bacteria in liquid, including unpasteurized juices. The study suggests that cinnamon may help control foodborne illnesses and potentially replace preservatives.
The INEEL is developing a roadmap for vadose zone management, leveraging expertise from DOE sites, contractors, industry, and universities to enhance timely delivery of products. The goal is sound environmental stewardship through understanding based on defensible science.
A study found that primary care physicians in California often miss opportunities to screen for domestic violence, especially during routine medical exams. The researchers recommend increasing awareness and training to prevent domestic violence from happening in the first place.
Graduate students will work with leaders in biorobotics and neuro-mechanical prostheses, designing agile robots and creating devices to restore movement. The program aims to educate scientists and engineers for multidisciplinary teams.
A team of 200 scientists has reconstructed the evolutionary relationships among all green plants, revealing a single common ancestor that spawned every plant species on Earth. The research also clarifies the relationships between plants and animals, overturning traditional categories.
Researchers at Max Planck Institute for Quantum Optics found that molecular clusters break up into positively and negatively charged fragments upon impact with any solid surface. They propose that neutral alkali atoms play a key role in charge separation, leading to the formation of separate ionic fragments.
