Well-designed visual aids improve risk understanding

Tuesday July 25th, 2017 07:42:01 PM
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.

Improved imaging of neonatal soft-tissue tumors can help radiologists improve patient care

Tuesday July 25th, 2017 07:41:59 PM
Better understanding of practical imaging techniques with regard to neonatal soft-tissue tumors can improve patient care, according to an article.

New shark species glows in the dark, weighs about 2 pounds and has a huge nose

Tuesday July 25th, 2017 04:56:18 PM
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.

Physical activity could combat fatigue, cognitive decline in cancer survivors

Tuesday July 25th, 2017 04:22:42 PM
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.

Cognitive cross-training enhances learning, study finds

Tuesday July 25th, 2017 04:22:33 PM
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.

Mind-body therapies immediately reduce unmanageable pain in hospital patients

Tuesday July 25th, 2017 04:22:28 PM
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.

How fear alone can cause animal extinction

Tuesday July 25th, 2017 04:22:24 PM
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.

Molecular hitchhiker on human protein signals tumors to self-destruct

Tuesday July 25th, 2017 04:21:57 PM
Engineers have found that an existing human protein is an ideal carrier for powerful molecules that can signal tumors to self-destruct.

Cosmologists produce new maps of dark matter dynamics

Tuesday July 25th, 2017 04:21:51 PM
New maps of dark matter dynamics in the Universe have been produced by a team of international cosmologists, outlines a new report.

Study points to penile microbiome as a risk factor for HIV in men

Tuesday July 25th, 2017 04:21:45 PM
Uncircumcised men with high levels of anaerobic penile bacteria at higher risk for HIV, suggests new research.

High prevalence of evidence of CTE in brains of deceased football players

Tuesday July 25th, 2017 04:21:24 PM
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.

Reversing tissue damage caused by heart attacks?

Tuesday July 25th, 2017 04:20:25 PM
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.

How texting can protect babies from sudden death

Tuesday July 25th, 2017 04:20:09 PM
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.

Feeling stressed during the workday? Playing video games may help

Tuesday July 25th, 2017 02:07:04 PM
Human factors/ergonomics researchers found that engaging in casual video game play during rest breaks can help restore mood in response to workplace stress.

Secret to giving the perfect gift: Stop being afraid

Tuesday July 25th, 2017 02:07:01 PM
People would prefer to receive sentimentally valuable gifts, but instead they often receive superficial gifts related to their personal preferences, researchers have found.

Dodder: A parasite involved in the plant alarm system

Tuesday July 25th, 2017 02:06:54 PM
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.

Symbiosis: Butter for my honey

Tuesday July 25th, 2017 02:06:49 PM
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.

Making polymer chemistry 'click'

Tuesday July 25th, 2017 01:04:45 PM
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.

Chemical route towards electronic devices in graphene

Tuesday July 25th, 2017 01:01:38 PM
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.

Climate change poses threat to European electricity production

Tuesday July 25th, 2017 01:01:06 PM
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.
