Analysis finds lower IQ in children with chronic kidney disease
Source: Science Daily
An analysis of published studies indicates that children with chronic kidney disease may have lower intellectual functioning compared than children in the general population. Compared with children with mild-to-moderate stage kidney disease and with kidney transplants, children on dialysis had the lowest IQ scores. Deficits were evident for attention, memory, and executive function domains.

A research study demonstrates in mice the biological relevance of sex in the effects of accelerated ageing caused by a chronic treatment of D-galactose, a sugar found abundantly in milk and to a lesser extent in fruits and vegetables. At high doses, this substance accelerates ageing in males, affecting them at sensory and motor level and in their neuro-immuno-endocrine system, while females experience alterations in learning and their ability to register information about their surroundings and orientation. However, at low doses the treatment has positive effects, especially in males.

Understanding a fly’s body temperature may help people sleep better

In findings that one day may help people sleep better, scientists have uncovered the first molecular evidence that two anciently conserved proteins in the brains of insects and mammals share a common biological ancestry as regulators of body temperature rhythms crucial to metabolism and sleep. The scientists study fruit flies (Drosophila) and mice to solve mysteries about body temperature rhythms in insects and mammals.

Progress, but far from perfection, on avoiding risky sedatives in older adults
Source: Science Daily
They help many people sleep, or feel calmer or less anxious. But in older people, they also double the risk of car crashes, falls and broken hips. That’s why the medications known as benzodiazepines show up on international guidelines as drugs that very few people over the age of 65 should take. Yet a sizable percentage of adults in that age group still have an active prescription for one, according to new research.

Researchers have used magnetic resonance imaging (MRI) scans that measure blood flow in the brain to better understand why people often become aggressive and violent after drinking alcohol. After only two drinks, the researchers noted changes in the working of the prefrontal cortex of the brain, the part normally involved in tempering a person’s levels of aggression.

Sleepless in Japan: How insomnia kills
Source: Science Daily
Lay people tend to think that insomnia is usually a symptom of something else, like stress, a bad diet or a sedentary lifestyle, but this may not be true at all. It is possible that insomnia itself causes many of the conditions that it is seen as a symptom of. Using previous research that shows that insomnia causes a decrease in blood flow in the front dorsal lobe of the brain, which correlates with depression, the authors seek to establish a link between insomnia and depression.

Studying deep brain tissues noninvasively is difficult. Now scientists have developed a way to send light deep into the brain without invasive optical fibers. The method uses infrared light outside the head to activate upconversion nanoparticles (UCNPs). When these nanoparticles absorb near-infrared laser light, they emit visible photons to deep areas in the brain, allowing remote optogenetic stimulation or inhibition of neurons in the brain.
