Researchers at Georgia Tech have applied aerodynamic concepts from aircraft to tractor-trailers, reducing drag by up to 50% and improving directional control, traction, and braking. The Circulation Control system uses compressed air to create lift and reduce rolling resistance, with potential fuel savings of up to 12%.
A Canadian Institutes of Health Research-funded study found that full-term breech presentation is safest with a planned caesarian section. Babies in the caesarian group were 3-4 times less likely to die or have serious problems within six weeks, especially in developed countries.
Harbor Branch researchers have isolated compounds from an Indian Ocean sponge that show promise as a new treatment for fungal infections, including those affecting AIDS patients. The discovery of unique cyclic peroxy acids may provide a more effective alternative to existing antifungal agents.
A Vanderbilt University research team has identified specific acoustic characteristics in the voices of individuals who have attempted or completed suicide. These findings suggest a potential new method for assessing suicidal intent and could be a valuable tool in preventing suicidal deaths.
Researchers found that fish and flies can differentiate according to specific habitats within nine and 13 generations, respectively. These findings provide a basis for studying the role of natural selection in species evolution and offer insights into the processes of rapid speciation in nature.
Researchers at University of Warwick develop Cybersphere, a VR system that allows users to move freely in virtual environments. The technology combines high power projectors and rotation sensors to provide a fully immersive visual experience.
A DNA vaccine paired with an immune protein successfully controls a highly pathogenic AIDS virus in monkeys, strengthening their immune response and preventing disease. The approach could decrease HIV-1 transmission rates by reducing viral replication in vaccinated individuals.
The researchers discovered a glycerol-conducting channel that selectively filters simple carbohydrates while blocking access to smaller water molecules and ions. This finding sheds light on how protein channels embedded in cell membranes work.
The university will offer 10 Chancellor's Teaching Assistantships with stipends and full tuition to encourage first-year students to participate in teacher training programs. The grant aims to increase minority Ph.D. enrollment at participating institutions.
A new complex launched at the University of Warwick features a 3D cinema that enables large groups of senior managers and engineers to visualize and collaborate on product design projects in 3D. This technology will facilitate geographically dispersed teams across large enterprises to work together more efficiently.
Researchers at Beth Israel Deaconess Medical Center developed an AIDS vaccine that harnesses "killer" T cells to suppress the virus and prevent clinical disease in monkeys. The vaccine showed significant success in boosting CD8 cytotoxic T lymphocytes, which can attack and contain HIV-infected cells.
Children's lung development is slowed due to air pollution, according to a comprehensive study. Lung function growth rates were 10% lower in the most polluted community compared to cleaner areas, with effects also observed in asthmatic and healthy children.
Partners in Amphibians and Reptile Conservation (PARC) received an Environmental Merit Award from the US Environmental Protection Agency Region 4. The organization, formed in 1999, has made significant contributions to long-term conservation of amphibians, reptiles, and their habitats through public/private partnerships.
