Reading summer camp? Study to examine how soon-to-be kindergarteners are wired for literacy
Reading summer camp? Study to examine how soon-to-be kindergarteners are wired for literacy
Picture this scene: A father reads a storybook to his young daughter, the girl seated in his lap and apparently fascinated by the illustrations of a bunny. Picture the same scene, neuroscientist version: Brain scans show activity in the father's primary visual cortex, extending to a specialized word recognition area, as he reads the text and glances at the drawings; in the child's brain, only the primary visual cortex and regions involved in recognizing the illustrations are activated.

Could genetic breakthrough finally help take the sting out of mouth ulcers?
A large breakthrough has been made in the genetic understanding of mouth ulcers which could provide potential for a new drug to prevent or heal the painful lesions. Mouth ulcers affect up to 25 per cent of young adults and a higher proportion of children. Previous research has shown that mouth ulcers are partially heritable, but until now there has been little evidence linking specific genes or genomic regions to mouth ulcers.

Three Ways Studying Organic Chemistry Changes the Brain
Academic learning is about gaining new knowledge and skill, but only recently has it been possible to see new knowledge appear in a human brain. A new study from Carnegie Mellon University researchers using multiple imaging modalities shows that learning scientific information results in changes in the actual structure of memory-related areas of the brain, changes due to the encoding of the new information in these memory-related brain areas, and changes in the coordination among the network nodes that jointly contain the new information.

Directed evolution builds nanoparticles
Directed evolution builds nanoparticles
Directed evolution is a powerful technique for engineering proteins. EPFL scientists now show that it can also be used to engineer synthetic nanoparticles as optical biosensors, which are used widely in biology, drug development, and even medical diagnostics such as real-time monitoring of glucose. The 2018 Nobel Prize in Chemistry went to three scientists who developed the method that forever changed protein engineering: directed evolution.

Linking bacterial populations with health
Two people may have different bacteria living on and in them, but the challenge is knowing which differences matter for health. Statistician Susan Holmes thinks she might have some answers to help scientists work out these links. We are all teeming with bacteria that help us digest food or fight disease, but two people might play host to a very different array of bacteria due to diet, where they live, hobbies or even medical histories.

Swimming microbes steer themselves into mathematical order
For News Media FOR IMMEDIATE RELEASE × A sheet of tiny swimming organisms that "push" themselves through fluid with, say, flagella, create forces in the liquid that bend the sheet in asymmetric, shrinking folds. Image courtesy of Saverio Spagnolie Freeing thousands of microorganisms to swim in random directions in an infinite pool of liquid may not sound like a recipe for order, but eventually the swarm will go with its own flow.

When watching others in pain, women's brains show more empathy
When watching others in pain, women’s brains show more empathy
It's a phrase many of us have uttered at one time or other: “I feel your pain.” However, the degree to which you actually feel another person's pain may depend on your sex. That was a key finding of a recent study by Leonardo Christov-Moore, a UCLA postdoctoral fellow in psychiatry and biobehavioral sciences, and Dr. Marco Iacoboni, director of the Neuromodulation Lab at the UCLA Ahmanson-Lovelace Brain Mapping Center , who studied the brain activity of people as they reacted to images of pain in others.
