Informed decision making depends on the ability to accurately evaluate and understand information about risk, suggests a new study. A state-of-the-science review of the literature concludes that visual aids are beneficial for diverse people with different levels of numeracy and graph literacy. The study identifies five categories of practical, evidence-based guidelines for the evaluation and design of visual aids.
Better understanding of practical imaging techniques with regard to neonatal soft-tissue tumors can improve patient care, according to an article.
Just as "Shark Week" is gearing up, researchers have discovered a new species of shark 17 years in the making. Like finding a needle in a haystack, it was well worth the wait as this elusive creature is yet to be seen in the wild.
A new study indicates that cancer patients and survivors have a ready weapon against fatigue and 'chemo brain': a brisk walk. Researchers looked at the association between physical activity, fatigue and performance on cognitive tasks in nearly 300 breast cancer survivors.
Just as athletes cross-train to improve physical skills, those wanting to enhance cognitive skills can benefit from multiple ways of exercising the brain, according to a comprehensive new study. The 18-week study of 318 healthy young adults found that combining physical exercise and mild electric brain stimulation with computer-based cognitive training promoted skill learning significantly more than using cognitive training alone. The enhanced learning was skill-specific and did not translate to general intelligence.
After participating in a single, 15-minute session of certain mind-body therapies, patients reported an immediate decrease in pain levels similar to what one might expect from an opioid painkiller. This study is the first to compare the effects of mindfulness and hypnosis on acute pain in the hospital setting.
Fear alone may contribute to the extinction of animal populations according to a recent study. When scientists exposed fruit flies to the scent of a praying mantis, a known predator, they found that the risk of extinction increased up to seven fold. The increased risk of extinction occurred because at small population sizes, as the flies spent more time being vigilant and less time eating, populations that declined could not quickly rebound.
Engineers have found that an existing human protein is an ideal carrier for powerful molecules that can signal tumors to self-destruct.
New maps of dark matter dynamics in the Universe have been produced by a team of international cosmologists, outlines a new report.
Uncircumcised men with high levels of anaerobic penile bacteria at higher risk for HIV, suggests new research.
Chronic traumatic encephalopathy (CTE) was diagnosed post-mortem in a high proportion of former football players whose brains were donated for research, including 110 of 111 National Football League players, according to a study.
A new discovery helps to explain how cells which surround blood vessels, called pericytes, stimulate new blood vessels to grow with the hormone 'leptin' playing a key role. Leptin is produced by fat cells which helps to regulate energy balance in the body by inhibiting the appetite. This study may have important implications for the treatment of heart attacks and also for cancer.
Educational videos delivered by text or email successfully encouraged new mothers to use safe sleep practices for their babies, reducing the risk of sudden unexpected infant death, a new study has found.
Human factors/ergonomics researchers found that engaging in casual video game play during rest breaks can help restore mood in response to workplace stress.
People would prefer to receive sentimentally valuable gifts, but instead they often receive superficial gifts related to their personal preferences, researchers have found.
Parasitic plants of the genus Cuscuta (dodder) not only deplete nutrients from their host plants, but also function as important 'information brokers' among neighboring plants, when insects feed on host plants, a team of scientists has discovered.
Textbooks tell us that, in arbuscular mycorrhizal symbioses, the host plant supplies its fungal symbionts solely with sugars, in return for inorganic nutrients. New findings now show that lipids are also on the menu.
A research team has developed a faster and easier way to make a class of sulfur-containing plastics that will lower the cost of large-scale production.
Essential electronic components, such as diodes and tunnel barriers, can be incorporated in single graphene wires (nanoribbons) with atomic precision. The goal is to create graphene-based electronic devices with extremely fast operational speeds.
The vulnerability of the European electricity sector to changes in water resources is set to worsen by 2030 as a consequence of climate change, conclude researchers.
