INDIANAPOLIS — A protein whose primary role is in the embryonic development of kidneys may play a future role in treating kidney failure.

A new study describes one of the mechanisms in which pathogenic bacteria populations control the way they spread over the surface of the organs they infect and stop when they detect the presence of an antibiotic, only to resume again when the effect wears off.
MANHATTAN, Kan. — A Kansas State University chemical engineer has developed and patented a chemical structure to make all-natural personal care products and purer pharmaceuticals in the laboratory.
K-State's Peter Pfromm, in collaboration with visiting scientist Kerstin Wurges, has engineered a way to use enzymes to efficiently catalyze chemical reactions to create things like scents for perfumes or to avoid the introduction of inactive ingredients in drugs.
WEST LAFAYETTE, Ind. - A Purdue University researcher hopes a better understanding of the neurological system of the body louse through the mapping of its genome will lead to better control or elimination of the human parasite.
Exposure to environmental levels of the industrial chemical bisphenol A, or BPA, in the womb and early life may cause long-lasting harm to testicular function, according to a new study conducted in animals. The results are being presented Monday at The Endocrine Society's 92nd Annual Meeting in San Diego.
The limited immune response in the eyes of freshwater fishes has created a great home for parasites, according to research published online in the journal Molecular Ecology. The study provides a lens into the evolutionary world of the larval flukes that parasitize Canadian fish.
In an article to be published on 21 June 2010 in the Journal of Clinical Oncology, researchers from Inserm (Inserm unit 625 – Research Group on Human and Mammalian Reproduction, University of Rennes 1), the CHU (University Hospital Centre) in Pointe à Pitre (urology department, University of the French West Indies and Guiana) and from the Center for Analytical Research and Technology (University of Liège, Belgique), show that exposure to chlordecone (also named Kepone), an organochlorine chemical with well defined estrogenic properties used in the French West Indies until 1993, is as
The results of the sequencing and analysis of the human body louse genome, which were published on June 21 in the Proceedings of the National Academy of Sciences (PNAS), offer new insights into the intriguing biology of this disease-vector insect. The project involved more than 70 international scientists led by Professor Evgeny Zdobnov at the University of Geneva Medical School and the SIB Swiss Institute of Bioinformatics, with Professor Barry Pittendrigh at the University of Illinois and Professor Ewen Kirkness at the J. Craig Venter Institute.
The UK's National Physical Laboratory (NPL) is involved in a collaborative project that is helping to further the understanding of HIV viral protein structure which could lead to new molecular medicines.
In May 2010 the project team, comprising biotechnology experts from NPL, the University of Edinburgh and IBM T.J. Watson Research Center, published some of their research in Journal of Physical Chemistry B.
Many primary school teachers admit they 'could do better'. Lack of resources or insufficient training has led to teaching that is often inadequate and lacking in confidence, claim researchers.
"Some of the reasons for the lack of positive promotion of disability in primary schools are; uncertainty about how to fit disability equality into the curriculum or a reluctance to talk about disability for fear of highlighting 'difference' " says the study.
The Endocrine Society presented its Scientific Statement on menopausal hormone therapy Monday in San Diego, Calif. at ENDO 2010: The 92nd Annual Meeting & Expo. The Scientific Statement, located at http://www.endo-society.org/journals/ScientificStatements/upload/jc-2009-2509v1.pdf, provides a comprehensive, objective evaluation of the benefits and risks associated with menopausal hormone therapy (MHT).
The robust jaws and formidable teeth of some of our ancestors and ape cousins may suggest that humans are wimps when it comes to producing a powerful bite: but a new study has found the opposite is true, with major implications for our understanding of diet in ancestral humans.
The surprise findings suggest that early modern humans did not necessarily need to use tools and cooking to process high-nutrient hard foods, such as nuts - and perhaps less tough foods such as meat - but may have lost an ability to eat very tough items, such as tubers or leaves.
College Park, MD (June 22, 2010) -- The Human Genome Project, along with numerous parallel efforts to solve the DNA sequences of hundreds of animal, plant, fungal, and microbe genomes in the last few decades, has produced enormous amounts of genetic data with which researchers are struggling to keep pace. Knowing gene sequences, after all, may not directly reveal what roles that genes play in the actual manifestation of physical traits (or phenotypes) of an organism -- including their roles in human diseases.
BOSTON, Mass. (June 20, 2010) – By emulating nature's design principles, a team at Harvard's Wyss Institute for Biologically Inspired Engineering, Harvard Medical School and Dana-Farber Cancer Institute has created nanodevices made of DNA that self-assemble and can be programmed to move and change shape on demand. In contrast to existing nanotechnologies, these programmable nanodevices are highly suitable for medical applications because DNA is both biocompatible and biodegradable.
The work appears in the June 20 advance online Nature Nanotechnology.
Los Angeles, CA (June 21 2010) In the wake of extensive television news reporting in Haiti by physicians such as Dr. Sanjay Gupta on CNN, guidelines for physician-journalists in covering disasters are proposed in the current issue of Electronic News, published by SAGE.
