Scientists have identified the first gene that is associated with a common childhood language disorder, known as specific language impairment (SLI). The gene — CNTNAP2 — has also been recently implicated in autism, and could represent a crucial genetic link between the two disorders.
Red-eyed treefrog embryos react to environmental oxygen concentration before they have blood or muscular movement. These initial responses to the environment may be critical to the frogs’ long-term survival.

An entomologist says smaller mosquitoes are more likely to be infected with viruses that cause diseases in humans.
Paper mill waste can safely be applied at a rate three times higher than the typical rate in Ohio, to reclaim soils of surface-coal mined areas.

In the near future it will be possible to customize the food we eat to individual needs, based on the genetic profile of the individual. Researchers suggest that the consumer market is not yet ready for this so-called nutrigenomics. They conclude that many obstacles must be overcome before products based on nutrigenomics become a reality.

A study in Nature Medicine describes the function and interaction of a critical molecule involved in cell death in Alzheimer’s disease patients. These new findings reveal that blocking this molecule, called Cyclophilin D, and development of surrounding mitochondrial targets may be viable therapeutic strategies for the prevention and treatment of Alzheimer’s disease, according to Shi [...]
Researchers in China and Switzerland are reporting the highest efficiency ever for a promising new genre of solar cells, which many scientists think offer the best hope for making the sun a mainstay source of energy in the future. The photovoltaic cells, called dye-sensitized solar cells or Grätzel cells, could expand the use of solar [...]

The human papillomavirus allows infected cervical and head and neck cancer cells to maintain internal molecular conditions that make the cancers resistant to therapy and more likely to grow and spread, resulting in a poor prognosis for patients.
