PROBLEM: Context: We have dreams almost every night. Do you ever notice the colors of your dreams? Do you dream in black and white or do you dream in yellow, red and green? New research suggests that the type of television you watched as a child has a great effect on the color of your dreams. While almost all people under 25 dream in color, thousands of people over 55, all of whom were brought up with black and white TV sets, often dream in monochrome . "It suggests there could be a critical period in our childhood when watching films has a big impact on the way dreams are formed", said Eva Murzyn, a psychology student at Dundee University in Britain who carried out the study. Research from 1915 through the 1950s suggested that the vast majority of dreams are in black and white. But the tide turned in the sixties, and later results suggested that up to 83 percent of dreams contain some color. Since this period also marked the transition between black-and-white film and TV and Technicolor ,an obvious explanation was that the media had been painting people's dreams. However, there weren't any firm conclusions. But now Miss Murzyn believes she has proven the link. She made a survey of more than 60 people, half of whom were over 55 and half of whom were under 25. She asked the volunteers to answer a questionnaire on the color of their dreams and their childhood exposure to film and TV. She then analyzed her own data. Only 4.4 percent of the under-25s' dreams were black and white. The over-55s who had had access to color TV and film during their childhood also reported a very low proportion of just 7.3 percent. But the over-55s who only had access to black-and -white media reported dreaming in black and white about a quarter of the time. Even though they would have spent only a few hours a day watching TV or films, their attention and emotion would have been heightened during this time, leaving a deeper imprint on their mind, Miss Murzyn told the New Scientist. "The crucial time is between three and ten when we all begin to have the ability to dream", she said.

PROBLEM: Context: The ubiquitously expressed iron storage protein ferritin plays a central role in maintaining cellular iron homeostasis. Cytosolic ferritins are composed of heavy (H) and light (L) subunits that co-assemble into a hollow spherical shell with an internal cavity where iron is stored. The ferroxidase activity of the ferritin H chain is critical to store iron in its Fe3+ oxidation state, while the L chain shows iron nucleation properties. We describe a unique case of a 23-yr-old female patient affected by a homozygous loss of function mutation in the L-ferritin gene, idiopathic generalized seizures, and atypical restless leg syndrome (RLS). We show that L chain ferritin is undetectable in primary fibroblasts from the patient, and thus ferritin consists only of H chains. Increased iron incorporation into the FtH homopolymer leads to reduced cellular iron availability, diminished levels of cytosolic catalase, SOD1 protein levels, enhanced ROS production and higher levels of oxidized proteins. Importantly, key phenotypic features observed in fibroblasts are also mirrored in reprogrammed neurons from the patient's fibroblasts. Our results demonstrate for the first time the pathophysiological consequences of L-ferritin deficiency in a human and help to define the concept for a new disease entity hallmarked by idiopathic generalized seizure and atypical RLS. 
 Question: Which deficiency is the cause of restless leg syndrome?

SOLUTION:
iron
