Researchers have developed a novel diagnostic technique to directly detect prions in the cerebrospinal fluid, which is easily accessible for diagnostic purposes. This breakthrough method uses dual-color scanning for intensely fluorescent targets to identify single prion particles with high sensitivity.
A study of 589 10-year-olds found that those exposed to tobacco in the womb were more likely to experiment with tobacco. Peer tobacco use, child delinquency, maternal depression, and child depression were also significant predictors of tobacco experimentation.
The MAXIMA experiment provides evidence for a flat universe, inflation, and a cosmological constant. The study confirms predictions made before the experiment, supporting the standard cosmology.
A national survey found that over 45% of US homes have bedding with dust mite allergen concentrations exceeding 2 micrograms per gram of dust, a level associated with allergy development. The study also revealed that 17% of household occupants reported cockroach infestations in the year prior to the study.
The NASA Marshall Open House offers a daylong space adventure with interactive exhibits, including a Space Shuttle Pavilion, magnetic levitation track and International Space Station mockup. Meet astronauts, robots and celebrities, and participate in activities like the Astronaut Moon Bounce.
A study by Cornell researchers found a close correlation between cowbird brain size and its singing ability, which attracts females. The research suggests that visual and sexual selection factors go hand-in-hand in determining mating success among male cowbirds.
A new study by Johns Hopkins researchers found that older adults with asthma are hospitalized at higher rates due to more severe symptoms and co-morbid illnesses. Earlier diagnosis and better medical care can help lower these hospital admission rates.
New research from the HOT Study reveals significant differences in the response to antihypertensive treatment between age and sex groups. Women with hypertension achieve target blood pressures more easily than men, while older patients exhibit improved blood pressure control and lower risk of adverse events.
A new study reveals that a commonly used DNA polymerase can withstand an unprecedented number of mutations without compromising its function. Researchers have identified 8,000 active mutant forms, which may have significant implications for understanding evolution, cancer research, and the development of new biotechnological applications.
A landmark survey reveals that 57% of Canadians with asthma do not have their illness adequately controlled. Many patients and physicians underestimate the severity of asthma, leading to poor control of symptoms.
A University of Washington study reveals that women who have Caesarean or assisted vaginal deliveries are at a higher risk of rehospitalization compared to those who have unassisted vaginal deliveries. The study found significant risks for complications such as uterine infection, postpartum hemorrhage, and cardio-pulmonary conditions.
A study by Cornell University researchers found that auditors tend to make more objective decisions than salespeople due to their legal liability. However, when salespeople are held accountable for their decisions, their bias is reduced. The study suggests that making decisions based on facts rather than personal biases can lead to bet...
Hot tubs can cause lung disease by dispersing bacteria through aerosolization, leading to symptoms like fever and weight loss. Removing the hot tub from the home is often the primary treatment for mild cases, while more severe cases require corticosteroids and antibiotics.
