Researchers developed a mathematical method to calculate the most economical travel routes between celestial bodies. The new route requires significantly less fuel consumption than previously described paths, with potential cost implications for space missions.
Researchers discovered a simple strategy for snakes to stand upright without limbs, concentrating bending and muscle activity into a short boundary layer near their base. This approach reduces energy required while maintaining balance, offering design principles for soft robots and medical devices.
Population risk-based screening using 5-year invasive breast cancer risk is associated with similar or greater benefits than age-based screening, as well as reduced false-positive recalls. As personalized medicine advances, risk-based screening is poised to become a cornerstone of breast cancer prevention.
A decision analytical model study estimates COVID-19 vaccination during pregnancy will continue to yield meaningful benefits, especially in reducing infant hospitalizations. COVID-19 vaccination has been shown to be safe for pregnant individuals.
Ensemble projections suggest vaccinating high-risk groups reduces disease burden, while broader vaccine availability saves more lives. Averted COVID-19 burden due to vaccination is robust across immune escape scenarios.
A recent study suggests that AI can provide real-time analysis of foods and support nutritionists in their work with patients. The study evaluates the consistency and accuracy of AI in providing energy and macronutrient information, showing promising results.
A team of researchers has developed a novel experimental system to simultaneously measure the mechanical properties and internal structure of rubber-like materials. The study found that strain within these materials is non-uniform, depending on the shape and size of composite particles.
An Aston University researcher has overturned a fundamental principle in construction by showing that a hanging chain and an arch are incompatible mechanical systems. This finding highlights the limitations of traditional analogies used to design and assess curved structures.
A decision analytical model study found that sustained public health interventions can reduce opioid-related overdose deaths. Implementing medications for opioid use disorder and increasing naloxone supply were key factors in reducing death rates.
A team of researchers from Korea investigated the dynamics of the p-Laplacian AC equation, finding that solutions maintain three criteria: phase separation, boundedness, and energy decay properties. They also identified an advantage of p-AC equation over classical Laplacian in adjusting interface sharpness.
The Li Faxin Research Group at Peking University has developed the world's first dynamic mechanical analyzer (DMA) suitable for hard materials. This instrument measures Young's modulus, shear modulus, and internal friction under variable temperature conditions, offering accurate and quick analysis of material properties.
Researchers at the University of Oregon have developed a method to manipulate sound waves in synthetic composite structures known as metamaterials. The discovery uses theoretical and computational analysis of mechanical vibrations of thin elastic plates to dynamically stop and reverse sound pulses.
A team at NYU Tandon School of Engineering has designed an artificial neural network approach that can predict the elastic modulus of graphene-enhanced composites from just one sample, streamlining materials testing. This reduces the need for extensive experimentation, lowering costs and accelerating product development.
