Researchers at Ohio State University found that pilots can detect changes in automation status more effectively when receiving vibrations than visual cues. The study suggests that tactile feedback could be a powerful tool for human-machine communication in various domains, including aviation, healthcare, and space exploration.
Researchers have connected lesions on the dorsal pons with multiple cases of musical hallucinations, a rare disorder where patients hear music in their mind. The study describes a quick onset of hallucinations without long-term hearing loss and sheds light on the condition's causes.
A comprehensive youth-led prevention program in Florida has helped reduce cigarette smoking among middle and high school students. The program, implemented in 1998, resulted in a 40% decline in current cigarette use among middle school students and an 18% decrease among high school students over the two-year period.
Research finds that cigar smoking causes cancers of the lung and upper aerodigestive tract, with risks approaching those of cigarette smoking. Environmental cigar smoke contributes significantly to indoor air pollution, posing health hazards.
A new study by Ohio State University researchers found that students who read essays on a computer screen struggled to comprehend the text and rated it as less interesting and less persuasive. Despite the same content, computerized texts were harder for students to understand, which may be due to different processing abilities.
A study found that controlling for education, occupation, and other factors did not substantially alter the death rate associated with tobacco smoking. The researchers' analysis used data from a large prospective cohort study and estimated 396,741 deaths attributable to smoking annually in the US.
A new amplification technique using nonlinear oscillators can convert signals' trajectories into symbols for enhanced communication. This technique has the potential to improve communications for ships and other vehicles in remote locations.
The University of North Carolina has won a $2.5 million grant from the National Institutes of Health to support the development of new women's health research careers. The five-year grant will provide salary support and protected time for six junior faculty members in medicine, obstetrics, pathology, and psychiatry.
Researchers found that smokers who continued using the smoking cessation aid Zyban gained an average of 9.02 pounds less than those on placebo over 45 weeks. Women in this group lost significantly more weight, with an average loss of 13.86 pounds at 52 weeks.
Researchers have established Canadian normative data for the SF-36, a widely used health-related quality of life measure. The study found that Canadians scored higher than US and UK counterparts in several domains.
College students are at risk of developing nicotine dependence due to the high prevalence of tobacco use, which includes smoking cigarettes and cigars. The study found that tobacco users also engage in other substance abuse behaviors, such as marijuana use and binge drinking.
A Duke University study found that carbon dioxide-enriched air accelerates pine tree reproduction, resulting in earlier maturation and higher seed production. This trend may have significant implications for forest regeneration and the Southeast's economy, where loblollies are a crucial forest product.
The National Space Science and Technology Center will bring together scientists, engineers, and educators to work on common goals of technology advancements. The center will provide expertise and advanced research opportunities for NASA's mission and the growing medical research sector in Alabama.
Scientists use declassified spy satellite images and aerial photographs to document an increase in both shrub numbers and area in a former arid grassland. The study reveals that honey mesquite bushes now dominate large areas of the Southwest, with most shrubs holding their ground despite early droughts.
Physician and nurse education may not be sufficient to reduce antibiotic overuse; restriction and concurrent review shown to lead to sustained improvement.
A study analyzing perinatal records found that 33.1% of pregnant women in Nova Scotia smoked before their pregnancy, with 69.9% continuing to smoke throughout. An accompanying commentary provides guidance for physicians to increase smoking cessation rates among pregnant women.
Researchers report a case where cluster headache symptoms appeared without head pain, suggesting primary symptoms. The study follows a 22-year-old man who experienced nasal stuffiness and pupil contraction in his left eye daily for weeks, without pain.
Researchers from Johns Hopkins Children's Center study 14 women with Complete Androgen Insensitivity Syndrome (CAIS), finding they can experience good libido and normal sexual activity without sensitivity to androgens. The study challenges current ideas about hormone-to-behavior interactions in humans.
The stern flap design has reduced the power required to propel Spruance and Ticonderoga-class destroyers, resulting in annual fuel savings of 3,600-4,700 barrels. The Navy plans to retrofit these ships with stern flaps, as well as Arleigh Burke and Oliver Hazard Perry classes, leading to an estimated $380 million in life cycle savings.
