Researchers at University of Illinois find that brain cells respond differently to rapid sound pulses compared to slow ones. This discovery challenges previous assumptions about the hearing system and could lead to more efficient building blocks for better hearing aids.
University of Pittsburgh researchers discovered a link between a genetic defect in mitochondria and the development of hereditary paraganglioma tumors. The study found that a defective gene on chromosome 11q23 causes cells to incorrectly sense oxygen levels, leading to chronic stimulation and tumor growth.
Hopkins researchers identified a dysfunction in HD that affects brain movement correction, leading to jerky movements. The study suggests that subtle jerkiness may appear before clinical symptoms, potentially providing an early diagnostic tool.
University of Illinois researchers simulate compressible foam to predict a dramatic morphological transition. They found that increased surface tension compresses most bubbles, forcing the remaining to expand and fill the space, leading to two distinct phases of foam.
A study by psychologists at the University of Warwick found that even with good academic knowledge of road safety rules, young children often miss danger signs when crossing roads. The researchers discovered that video materials are more effective in teaching children about road dangers than simple line drawings.
Researchers created a DNA microarray called Lymphochip to analyze gene expression in normal and malignant cells, revealing two distinct forms of DLBCL with different clinical outcomes. The study improved diagnosis and treatment of these lymphomas by providing a detailed molecular portrait of the disease.
A study published in Science demonstrates the utility of ARIAD's RAPID technology, which allows for rapid and regulated delivery of therapeutic proteins. Human insulin was successfully delivered to diabetic mice via this method, correcting blood sugar levels within minutes.
Researchers at the University of Illinois have discovered that fluorine can significantly enhance boron combustion in energetic propellants. The addition of fluorine reduces ignition delay time and total combustion time, leading to improved rocket performance and increased payload capacity.
Physicists at the University of Illinois have made new measurements that provide information about how different flavors of quarks in a proton generate its magnetic moment. The results suggest that the contribution from the strange quark is significantly positive, contrary to most theoretical models.
The companies identified a family of proteins called Potassium Channel Interacting Proteins (KChIPs) that regulate A-type potassium channels, which control brain electrical signals. These KChIPs may lead to the development of new therapeutics for CNS disorders with minimal side effects.
A recent study found that breastfeeding protects against infectious diseases such as pneumonia and diarrhea, resulting in a significant reduction in infant mortality. The protection diminishes with advancing age, but is greater for infants of women with low educational status. Exclusive breastfeeding may also reduce mother-to-child tra...
Researchers suggest a genetic expansion in the development of limbs, allowing early vertebrates to develop toes and fingers. The discovery sheds light on how nature has reused existing genes to create new adaptations for life on land.
A study published in The Lancet found that El Nino increased diarrheal disease admissions by 200% in children from 1993-1998. Diarrhea causes one billion episodes and three million deaths annually in children under five worldwide, and the researchers estimate a significant increase in cases with each degree of temperature rise.
Researchers used harmonic radar to track honey bees during orientation flights, revealing they learn to navigate by flying faster and visiting more areas. The study suggests that orientation flights allow bees to adapt to new environments, but the scientists still want to know why some bees take more or fewer flights.
A Purdue University engineer is working on software tools that can prevent design conflicts and improve the efficiency of e-workers. The tools use 'neuro-fuzzy' programs to identify conflicts and provide fine details about their nature, enabling a resolution.
