Nerve navigation findings prompt new direction for spinal cord research

Researchers at Medical College of Georgia have found that an enzyme called focal adhesion kinase plays a crucial role in guiding axons across the midline of the spinal cord during development. This discovery provides new insights into normal nervous system development and offers potential targets for treating spinal cord injuries.

Powering the future

The Florida Institute of Technology has launched a hydrogen fuel cell research center with a focus on developing new mainstream energy sources. The center, which brings together faculty from various colleges, aims to pool expertise and solve complex problems in the field.

Radiotherapy + cetuximab significantly improve disease control and survival in head and neck cancer

Combination therapy of radiotherapy and cetuximab significantly improves loco-regional control, median survival, and overall survival rates in patients with loco-regionally advanced squamous cell carcinoma of the oropharynx, hypopharynx, or larynx. The treatment also showed minimal enhancement of toxicity compared to radiotherapy alone.

A time to rhyme

A new study found that younger children primarily process words based on phonology, sound, whereas older children and adults process words based on semantics, meaning. Researchers tested the language processing abilities of children aged five, eight, and 11 using a rhyme-based experiment.

'Aggregate and the Environment'

The book provides detailed explanations of procedures used to manage and minimize environmental impacts of aggregate mining, processing, and transportation. It also highlights successful reclamation projects that convert mined areas into beneficial uses such as recreation areas and natural habitats.

Can't place a name to the face you just saw?

A team of researchers from the University of Arizona used fMRI to investigate how brains recognize faces and retrieve associated names. They found that specific areas, including the medial prefrontal cortex, showed activation during 'feeling-of-knowing' states, suggesting additional processes aid in recalling accurate memories.

Almost good enough to eat

Researchers found that Brazilian communities in coastal areas and the Amazon region have taboos on consuming certain fish species, especially predatory ones. These prohibitions are likely biologically adaptive, suggesting a link to toxic accumulation and health concerns.

AGU Journal highlights - 26 October 2004

Researchers have made significant discoveries about the impact of human activities on the environment. A new study used satellite observations to estimate nitrogen oxide emissions from ships, which contribute approximately 23 gigagrams per year into the troposphere. Additionally, a seismic analysis technique has provided unprecedented ...
