Researchers at Georgia Tech discovered a way to reduce friction in mechanical systems by rapidly oscillating the width of the lubricant-filled gap separating two sliding surfaces. This technique maintains disorder in the lubricant, preventing molecular layering that can increase friction.
The UT Southwestern pediatric laboratory now has a Time-of-Flight mass spectrometer, allowing for local analysis of chemotherapeutic drugs and other substances. This technology aids in identifying molecular minutiae, potentially resolving side effects such as fatigue and cognitive problems associated with chemotherapy.
Research on Nicotiana attenuata reveals that induced defenses can have both ecological benefits and costs, including resource-based costs and potential negative impacts on seed production. The discovery of endogenous wound signals, such as jasmonic acid, has provided tools to activate defenses independently of herbivore attack.
A review of Occupational Safety and Health Administration (OSHA) enforcement strategies concludes that current efforts are too slow and uncertain, leading to inadequate protection for workers. The authors suggest innovations such as worker education programs and devolving enforcement powers could improve safety further.
The conference will bring together over 100 principal investigators to discuss recent microgravity materials science research, including results from the Microgravity Sciences Laboratory-1 (MSL-1) mission. Researchers will also preview plans for the International Space Station and its Materials Science Research Facility.
A new study finds that unequal income distribution in US metropolitan areas is associated with a significant increase in mortality rates, exceeding the combined loss of life from several major causes. The research suggests that reducing economic inequalities should be a high priority to mitigate this burden.
Researchers at UT Southwestern Medical Center found that walking during the first stage of labor had no impact on labor duration, pain management, or infant outcomes. Women who walked showed similar results to those who rested in bed, with most indicating they would walk again in future labors.
A new University of Michigan study reveals that areas with high income inequality and low average incomes have significantly higher mortality rates, comparable to the combined loss of life from various diseases. The findings highlight the importance of considering equitable income distribution in public health assessments.
Astronomers detected a series of at least 26 starquakes, leading to the discovery of SGR 1627-41, the fourth conclusively identified SGR. The new SGR is believed to be caused by massive starquakes and has been linked to a supernova remnant.
Phytoplankton, tiny marine plants and bacteria, have evolved to stabilize the Earth's atmosphere by regulating atmospheric carbon dioxide levels. They convert sunlight into oxygen and sequester carbon deep in the ocean, influencing climate regulation.
