Toddler Brain Scan Gives Language Insight
The brain has a critical window for language development between the ages of two and four, brain scans suggest. Environmental influences have their biggest impact before the age of four, as the brain's wiring develops to process new words, say UK and US scientists. The research in The Journal of Neuroscience suggests disorders causing language delay should be tackled early. It also explains why young children are good at learning two languages. Continue Reading
Pentagon Seeks to Design Virus-Fighting Protein 'Cocktails'
The U.S. Defense Department is weighing a new search for immune-protein "cocktails" it hopes will protect humans against Ebola and other deadly, weapon-usable viruses. The Pentagon two weeks ago invited scientists to submit research proposals for designing "monoclonal antibodies" that could protect Continue Reading
Keys Uncovered to Antibiotic Resistance in MRSA
University of Notre Dame researchers Shahriar Mobashery and Mayland Chang and their collaborators in Spain have published research results that show how methicillin-resistant Staphylococcus aureus (MRSA) regulates the critical crosslinking of its cell wall in the face of beta-lactam antibiotics. The work, published in the Proceedings of the National Academy of Sciences, reveals the mechanistic basis for how the MRSA bacterium became such a difficult pathogen over the previous 50 years, in which time it spread rapidly across the world.Continue Reading
