Internationally Adopted Children Shed Light On How Babies Learn Langua
Each year, about 40,000 children are adopted across national lines, primarily by families from North America and Western Europe. Although most are infants and toddlers, thousands of older children are also adopted. Jesse Snedeker of Harvard University believes that these older children can help us understand how infants learn their native language. Early language development follows a predictable series of milestones. Babies initially say one word at a time, and mostly use nouns ("ball") or social words ("hi"). As they grow older their sentences become longer and more complex, as verbs ("take") and grammatical words ("about") begin to appear. Virus Used To Create Experimental HIV Vaccines Directly Impairs Immune
Leading efforts to create an HIV vaccine have hinged on the use of viruses as carriers for selected elements of the HIV virus. Recently, however, evidence has emerged that some of these so-called viral vector systems may undermine the immune system and should not be used for vaccine development. Now, a new study provides strong support for the idea that some viral-vector vaccines may cause more harm than good. From A Few Wild Ancestors, A Citrus Cornucopia
Whether it's a halved grapefruit sprinkled with sugar, mandarin slices tumbled in a green salad, mouth-puckering lemon wedges or a classic navel orange, there are probably enough kinds of citrus to satisfy any personality or taste. Rats With Migraines Provide Jefferson Scientists Insights To Improved
When Michael Oshinsky, Ph.D., gives his rats a headache, he has good reason.The animals are helping Dr. Oshinsky study how migraine treatments work. In recent experiments, the animals provided evidence showing that DHE, a standard drug currently used to treat acute migraine pain can also work against the onset of a phenomenon called "central sensitization,"or "allodynia,"which involves, as most migraine sufferers know, a heightened sensitivity to touch. Oral Osteoporosis Meds Appear To Reduce The Risk Of Jaw Degradation
Contrary to recent reports, oral osteoporosis medications that inhibit bone breakdown reduce the risk of jaw problems, based on an analysis of medical claims. Some doctors and dentists had advised patients who take oral osteoporosis medications such as Fosamax and Boniva to postpone dental work, fearing that tooth extractions and other procedures would exacerbate jaw problems purportedly linked to the medication. But the new findings refute the link and suggest the benefits of dentistry likely outweigh the risks for many of these patients. A New Key To Detecting Deadly Aortic Aneurysms
Scientists have discovered a way to use a simple blood test that may accurately detect thoracic aneurysm disease (TAA), which gives little warning and is almost always fatal if untreated. TAAs occur in the part of the aorta that passes through the chest. They can become huge without causing symptoms. More Love, More Hurt: New Study Looks At Hurt Feelings In Relationship
A new study finds that hurt feelings in relationships reflect on the perceived value of yourself, your partner, and the relationship. Compounds Found In Cruciferous Vegetables Block Lung Cancer Progressio
A family of compounds found in cruciferous vegetables, such as broccoli, cauliflower, and watercress, blocked lung cancer progression in both animal studies and in tests with human lung cancer cells, report researchers from Georgetown University Medical Center and the Institute for Cancer Prevention. DNA-scanning Technology Finds Possible Sites Of Cancer Genes In Chromo
With equipment designed to probe the smallest segments of the genetic code, researchers at Dana-Farber Cancer Institute and collaborating institutions have found something much larger: sections of the chromosomes of lung cancer cells where cancer-related genes may lurk.
