Scientists streamline method for making key virus

By devising a novel way to package the genome of a common human tumor virus — the virus that causes common warts, genital warts and that is implicated in prevalent cancers — scientists have paved the way for making the pathogen far more accessible to biomedical science.

The work, reported today (June 13) in the online edition of the Proceedings of the National Academy of Science (PNAS), promises to accelerate the search for an effective cancer vaccine and treatments for cervic

MicroRNA tweaks protein that controls early heart development

Researchers at UT Southwestern Medical Center have discovered how a small molecule of RNA called microRNA – a chemical cousin of DNA – helps fine tune the production of a key protein involved in the early development of heart muscle.

The findings, available in the online edition of the journal Nature, may aid scientists in their understanding of how a progenitor cell, or stem cell, decides to become a heart cell, as well as offer researchers a way to predict how other microRN

Autism and X-fragile syndrome

According to the World Health organisation, the definition of autism is based on a specific pattern of behaviour characteristics, as neither its aetiology nor pathology is defined. This is why a search for autism markers is proposed at three levels: morphological, cytogenetic and molecular.

In the 80s, a research group at the Leioa campus of the University of the Basque Country worked on dermatoglyphs, an analysis technique applied to autistic children. Dermatoglyphs, or handprin

A life-saving black box for cars

A car that can automatically alert emergency services in the event of an accident, giving its precise location and the health status of occupants would save thousands of lives each year. Thanks to the work of AIDER such a vehicle is a step closer to becoming reality.

Developed over three years by 10 partners under the European Commission’s IST programme, the AIDER system has been completely tested in the field and, from the car maker’s perspective, contributes towards meeting the

Scientists create digital bacteria to forge advances in biomedical research

Biological assays on computer study molecular basis of cellular behavior

Scientists at the University of Chicago and Argonne National Laboratory have constructed a computer simulation that allows them to study the relationship between biochemical fluctuations within a single cell and the cell’s behavior as it interacts with other cells and its environment.

The simulation, called AgentCell, has possible applications in cancer research, drug development and combating b

Rapid-scanning doppler on wheels keeps pace with twisters

A multibeam Doppler radar that can scan tornadic storms every 5 to 10 seconds is prowling the Great Plains through June 30 in search of its first close-up tornado. Engineers at the National Center for Atmospheric Research in Boulder helped build the Rapid-Scan Doppler on Wheels (DOW).

Together with a powerful analysis technique pioneered by NCAR scientist Wen-Chau Lee, the radar–newly enhanced for its first full spring of thunderstorm tracking–promises the most complete picture
