Weekly fish consumption linked to better sleep, higher IQ

Children who eat fish at least once a week sleep better and have IQ scores that are 4 points higher, on average, than those who consume fish less frequently or not at all, according to Science Daily.

Previous studies showed a relationship between omega-3s, the fatty acids in many types of fish, and improved intelligence, as well as omega-3s and better sleep. But they've never all been connected before. Professor Adrian Raine, reveals sleep as a possible mediating pathway, the potential missing link between fish and intelligence.

Stop sleeping with your cell phone

The scientists warned that people need to keep their cell phones several feet away from them to reduce radiation exposure and health risks.

Researchers released guidance for reducing exposure to cell phone radiation, amid mounting evidence that cell phone use may be linked to cancer, attention, mental health and reproductive health issues, according to Daily Mail.  

Cell phones transmit information using low frequency radio signals, which may expose us to unhealthy radiation, especially when streaming or downloading large files.

Research has not been able to prove definitively that cell phone radiation is dangerous, but there have been enough studies linking the two to warrant caution, especially for children.

Study prompts new ideas on cancers’ origins

Rapidly dividing, yet aberrant stem cells are a major source of cancer. But a new study suggests that mature cells also play a key role in initiating cancer -- a finding that could upend the way scientists think about the origins of the disease.

Researchers have found that mature cells have the ability to revert back to behaving more like rapidly dividing stem cells. However, when old cells return to a stem cell-like status, they can carry with them all of the mutations that have accumulated to date, predisposing some of those cells to developing into precancerous lesions, according to Science Daily.

Your mood depends on the food you eat, and what you should eat changes as you get older

Diet and dietary practices differentially affect mental health in young adults versus older adults, according to new research.

Lina Begdache, assistant professor of health and wellness studies, conducted an anonymous internet survey, asking people around the world to complete the Food-Mood Questionnaire (FMQ), which includes questions on food groups that have been associated with neurochemistry and neurobiology. Analyzing the data, Begdache and Assistant Professor found that mood in young adults (18-29) seems to be dependent on food that increases availability of neurotransmitter precursors and concentrations in the brain (meat). However, mood in mature adults (over 30 years) may be more reliant on food that increases availability of antioxidants (fruits) and abstinence of food that inappropriately activates the sympathetic nervous system (coffee, high glycemic index and skipping breakfast), according to Science Daily.

Symptoms of autoimmune diseases worse depending on time of day

A new study has revealed that the symptoms of autoimmune diseases get worse depending on the time of day and how your body clock is working.

Hundreds of millions of people around the world suffer from a range of autoimmune diseases including arthritis, lupus and celiac disease, according to RT.
