Summary:

A new study reveals babies as young as 15 months can learn the value of hard work. Researchers found babies who watched an adult struggle to reach two different goals before succeeding tried harder at their own difficult task than babies who saw an adult succeed effortlessly.

Diet sodas may be tied to stroke, dementia risk

ulping down an artificially sweetened beverage not only may be associated with health risks for your body, but also possibly your brain, a new study suggests.

Artificially sweetened drinks, such as diet sodas, were tied to a higher risk of stroke and dementia in the study, which published in the American Heart Association’s journal Stroke on Thursday.

Young Blood Infusions “Rejuvenate” Old Mice

An injection of “new blood” is a phrase long used as a metaphor for the revitalizing effect of fresh minds on a stagnant organization. But research now suggests it also applies in a literal sense. In a development that calls to mind both vampire lore and stories of bathing in blood, young blood appears to in fact rejuvenate old brains.

The Effect of Font Size on Reading Comprehension

Research on reading development has focused on the linguistic, cognitive, and recently, metacognitive skills children must master in order to learn to read. Less focus has been devoted to how the text itself, namely the perceptual features of the words, affects children’s learning and comprehension. In this study, we manipulated perceptual properties of text by presenting reading passages in different font sizes, line lengths, and line spacing to 100 children in the second and fifth grades. For second graders (Experiment 1), decreasing font size, as well as increasing line length, yielded significantly lower comprehension scores. Line spacing had no effect on performance. For fifth graders (Experiment 2), decreasing font size yielded higher comprehension scores, yet there were no effects for line length and line spacing. Results are discussed within a "desirable difficulty" approach to reading development.

Adolescent Brains are Works in Progress

Over the past 25 years, neuroscientists have discovered a great deal about the architecture and function of the brain. Their discoveries have led to huge strides in medicine, from pinpointing the timing at which children should be operated on for vision problems to shedding light on the mechanisms that cause such diseases as schizophrenia. Much of the early focus of the research was on the early years of development or on diseased brains. Now, with the advent of new imaging techniques, researchers are able to examine normal brains and brains of people throughout their lives.

New Drug Could Treat Alzheimer's, Multiple Sclerosis and Brain Injury

CHICAGO --- A new class of drug developed at Northwestern University Feinberg School of Medicine shows early promise of being a one-size-fits-all therapy for Alzheimer’s disease, Parkinson’s disease, multiple sclerosis and traumatic brain injury by reducing inflammation in the brain.

Northwestern has recently been issued patents to cover this new drug class and has licensed the commercial development to a biotech company that has recently completed the first human Phase 1 clinical trial for the drug.   

A Giant Neuron Has Been Found Wrapped Around the Entire Circumference of the Brain

For the first time, scientists have detected a giant neuron wrapped around the entire circumference of a mouse's brain, and it's so densely connected across both hemispheres, it could finally explain the origins of consciousness. 

Using a new imaging technique, the team detected the giant neuron emanating from one of the best-connected regions in the brain, and say it could be coordinating signals from different areas to create conscious thought.
