Researchers found that patients with either a third heart sound or elevated jugular venous pressure were more likely to have progressive heart failure and subsequent hospital visits due to heart failure. The study highlights the importance of physical examinations in predicting outcomes for heart failure patients.
A study found that socially stressed mice were twice as likely to die after infection with a compound than physically stressed mice. The researchers believe social stress intensified the immune response, leading to toxic shock and organ damage.
Researchers at the University of Pennsylvania will explore ways to incorporate a focus on embedded computer reliability into product design, developing models and analysis tools to identify potential bugs. The goal is to improve product dependability and reduce costs by predicting reliability earlier in the design phase.
A study by UF researchers found that most sedentary adults overestimate the intensity of their moderate activities, with only a small percentage reaching high-intensity levels. The findings suggest that better guidance is needed for adults to define their level of activity and receive the greatest cardiovascular benefits.
The new global network of listening posts will track atmospheric signals from diverse events like secret nuclear tests, volcanic eruptions, and hurricanes. Infrasound energy is generated by meteors, chemical explosions, supersonic aircraft, tornadoes, landslides, earthquakes, and volcanoes.
A team of Belgian and French astronomers have discovered three distant stars with extremely high Lead abundances, exceeding other elements heavier than Iron. This finding aligns with current stellar models predicting the buildup of heavy elements in stellar interiors.
Researchers suggest that Yasmin, with its unique progestin ethinyl estradiol combination, holds promise for reducing PMDD symptoms and improving women's lives. A three-month study found that 82 women taking Yasmin showed greater improvement than the placebo group.
The partnership aims to explore the impact of protein folding on diseases using IBM's Blue Gene research project and ORNL's supercomputing power. This effort will scale computer performance to petaflops, enabling breakthroughs in biology, climate science, and nanotechnology.
Brittlestars, also known as serpent stars, possess a unique 'visual' system that enables them to detect shadows and escape from predators. Their skeletal elements feature crystal lenses that transmit light to their nervous system, allowing them to respond to light changes.
Researchers have shed light on the brutal treatment of Maya scribes who supported defeated kings. The scribes' fingers were broken before they were executed, as part of a bizarre practice that muffled their ability to produce powerful texts. This practice highlights the importance of these scribes in Maya society.
Researchers at Ohio State University found that social stress makes specific immune cells resistant to corticosterone, a hormone regulating inflammation. This resistance can lead to uncontrolled inflammation, increasing the severity of infections and tissue damage.
A new study from Ohio State University finds that Republican presidents are associated with increased US prison populations. The research controlled for various factors and found a significant correlation between Republican administrations and rising prison rates.
Two Cornell University researchers are working on separate projects to develop new devices that could lead to huge increases in data storage and processing speed. George Malliaras is investigating the electrical properties of individual molecules, while Robert Buhrman is studying spin manipulation and quantum manipulation.
A new study published in the Journal of Women’s Health and Gender-Based Medicine found that oral contraceptive Yasmin significantly reduces premenstrual pain, acne, and food cravings associated with PMDD. The study enrolled 82 women aged 18-40 who experienced severe PMS symptoms.
Scientists use ion-trap secondary ion mass spectrometer (IT-SIMS) to detect chemical warfare agents like HD and VX at part-per-million levels. The technique offers increased specificity, speed, and minimal sample preparation, making it ideal for environmental restoration and national security applications.
Researchers at U-M discovered nearly 200 genes with varying expression profiles in normal and malignant prostate tissue. The study identified new clinical biomarkers, hepsin and pim-1, which were correlated with patient prognosis and could lead to new diagnostic tests.
