Imaging pain

Dr. Bushnell's laboratory uses human brain imaging techniques to study pain, finding four key brain regions involved in the experience. Activity in these regions is linked to emotional responses to pain, suggesting that psychological state can alter its perception.

Is there a critical period for sign language?

Dr. Rachel I. Mayberry's research indicates that there is a critical period for sign language acquisition, guiding the learning of all first languages. This critical period emphasizes the importance of early childhood exposure and language acquisition in order to achieve optimal comprehension.

Do mitigated wetlands really work? Only time will tell

A study by Ohio State University's William Mitsch explores the performance of two experimental wetlands, one of which is 20% more productive but less diverse in plant species. Both wetlands contribute equally to reducing nitrates, but their long-term fate remains uncertain.

Critical stage in infant development identified for language acquisition

A landmark CU-Boulder study confirms that early detection and intervention for infants with hearing loss has a significant positive impact on their subsequent language abilities. Infants identified within the first six months showed improved expressive vocabulary development compared to those identified after six months.

LSU professor takes new field of hurricane research by storm

A new LSU study reconstructs past hurricane landfalls dating back 5,000 years and finds the US has a low incidence of major hurricane landfalls along the Gulf Coast over the past 1,000 years. The study provides concrete information on catastrophic hurricane landfalls in the US, with a likelihood of once every 300-600 years.

Gene therapy halts HIV replication in cells from infected patients

Researchers have developed an antitat gene therapy that blocks HIV replication in cells from infected patients, prolonging survival of immune system cells and potentially maintaining the virus in a dormant state. The approach combines genetic engineering and antisense technology, offering a promising new strategy for treating AIDS.
