Researchers found that patients with higher cognitive adaptation scores were less likely to experience a new heart attack or other coronary event six months after their angioplasty. Patients' ability to cope positively with their illness and take better care of themselves may play a key role in reducing the risk of future heart attacks.
Researchers suggest that a rare radioactive isotope found in deep-sea sediments may be evidence of a nearby supernova. The explosion could have caused a 'cosmic-ray winter' leading to mini-extinctions about 5 million years ago, with effects still detectable today.
Research finds that revival in AIDS patients brings new uncertainties, affecting feelings of hope and future orientation, social roles and identities, interpersonal relationships, and changes in quality of life.
Researchers have developed a system to network up to 30 remote sensors along a single fiber optic cable, allowing for periodic assessments of structural strain. The Navy and Federal Highway Administration are exploring the use of this technology to schedule maintenance and update design codes.
A University of North Carolina at Chapel Hill study highlights the dangers of heatstroke in football and recommends shorter practices, non-contact drills, and regular cooling breaks. Coaches are urged to prioritize player safety and prevent tragedies.
A recent study found that approximately 4.2 million adolescents had no health insurance coverage in 1995, leaving them with significant obstacles to accessing adequate healthcare. The study suggests that a shift from private to public insurance has not led to an improvement in health insurance coverage for this age group.
Researchers at UW-Madison have perfected a method for creating designer influenza viruses, which can be tailored to solve mysteries about flu strain mutations, spread, and illness. This technology may lead to more efficient influenza vaccines and safer gene therapies.
A CAD-driven laser forming process may eliminate costly manufacturing practices for aircraft structural components. This technology aims to reduce material usage, inventory, and costs by leveraging a layered manufacturing method.
Researchers at the University of Illinois have improved the chemical oxygen-iodine laser (COIL), enhancing its performance and reducing operating costs. The device can now be scaled to high power levels and has a wavelength suitable for remote fiber-optic delivery.
Scientists at the University of Iowa have discovered a powerful tool to activate human dendritic cells, key players in the immune system, using CpG DNA. This breakthrough could lead to enhanced immunization and treatment of cancer and autoimmune diseases.
Researchers found that oxygen supplementation can significantly reduce the effects of retinal detachment by protecting photoreceptor cells and limiting cell abnormality. This breakthrough suggests that ophthalmologists may want to consider providing oxygen therapy to patients diagnosed with retinal detachment while awaiting surgery.
Researchers found that long-term Transcendental Meditation practitioners experience reduced systolic blood pressure and vasoconstriction during meditation. This study suggests that Transcendental Meditation may help prevent high blood pressure in African American youth by reducing risk factors for heart disease.
A new sensing and control system is being developed to regulate melt rate, temperature, and iron composition in cupola furnaces, reducing greenhouse gas emissions. The Intelligent, Integrated, Industrial Process Sensing and Control System (I3PSC) has the potential to save 1500 tonnes of coke annually in the US alone.
A study by Stanley Changnon and colleagues found no evidence of an increase in catastrophic weather events, despite rising property losses. The growth of losses is attributed to the increasing population in coastal and urban areas, leading to a larger target-at-risk.
Researchers developed a novel afterburner technology that increases waste consumption in marine incinerators by a factor of 3.2 while reducing carbon monoxide emission by the same amount. The technology also eliminated visible smoke emission during operation.
NASA's PICASSO-CENA mission aims to measure the impact of tiny particles from industrial pollution on sunlight and climate change. The mission will use lidar technology to gather data on aerosols, clouds, and their effects on regional climate.
A study from Massachusetts General Hospital found that treated ADHD boys are one-third as likely to develop substance abuse or dependence compared to untreated peers. The research contradicts the myth that stimulant treatment could lead to future drug abuse.
A new study funded by NIDA and NIMH found that boys with ADHD treated with stimulants like Ritalin are less likely to develop substance use disorders. The study showed an 84% reduction in risk among medicated ADHD boys, compared to non-medicated ADHD boys and those without ADHD.
A study found that patients with chronic nonmalignant back pain who received higher levels of economic and social rewards experienced increased disability, depression, and anxiety. Those with fewer rewards reported lower levels of these conditions.
Researchers have successfully reversed damage caused by Pompe disease, a rare inherited muscle-wasting disorder, in laboratory mice using a modified virus to deliver a therapeutic gene. The study's findings show promise for treating dozens of forms of muscular dystrophy and may lead to a continuous supply of enzyme production.
New research reveals that uncontrollable stresses can severely affect the immune system by disrupting cytokine function and producing high levels of cortisol. In contrast, controlled stress responses result in brief, insignificant changes to immune activity.
Scientists have discovered a highly error-prone DNA copying system in bacteria that causes genetic mutations under ultraviolet radiation. This 'sloppier copier' reveals how cells can intentionally introduce mistakes to survive and evolve.
A new study found that patients with higher levels of conscientiousness are less likely to die suddenly from cardiovascular disease. Patients who faithfully take their prescribed medication, such as amiodarone, are also more likely to engage in healthy behaviors like eating a heart-healthy diet and socializing.
A $1.4 million project aims to create an advanced artificial knee prosthesis, drawing on expertise from US and Russian nuclear labs. The device will be designed to adapt to the wearer's movement and provide a more natural gait.
A recent study found that caregivers of mentally ill individuals are at a high risk of physical illness, with the severity of symptoms predicting burden and infections. Social support played a crucial role in reducing caregiver burden and infections.
A recent study by Carnegie Mellon University researchers found that patients with a positive outlook and strong sense of control over their lives are less likely to experience a second coronary event. Those with low self-esteem, optimism, and feelings of control were two and a half times more likely to suffer from restenosis.
A longitudinal study found that children who exhibited more imagination and emotion in their early play were more creative and better copers as they aged. The research suggests that early interventions can help young children develop essential skills for lifelong creativity and problem-solving.
