Cell phones and brain cancer - major research initiatives needed

Major research initiatives are needed immediately to assess the possibility that using cellular phones may lead to an increased risk of brain tumors, according to an editorial in the November issue of the journal Surgical Neurology, published by Elsevier.

Discovery of genetic switch critical for cell survival in Hypoxia

Researchers at the University of California, San Diego School of Medicine have identified a critical metabolic "switch" in fruit flies that helps oxygen-deprived cells survive. "A transcriptional suppressor, called hairy, is crucial for reducing the mismatch between supply and demand of oxygen," said Dan Zhou, first author on the study, published October 17 in the open-access journal PLoS Genetics.

Gene could 'knock the sox' off cancer!

Australian scientists from the Institute for Molecular Bioscience at The University of Queensland (UQ), have identified a gene which could very well 'knock the sox' off cancer and lymphatic disorders.

Contact lenses are home to pathogenic amoebae

Contact lenses increase the risk of infection with pathogenic protozoa that can cause blindness. New research, published in the November issue of the Journal of Medical Microbiology, shows that a high percentage of contact lens cases in Tenerife are contaminated with Acanthamoeba that cannot be killed by normal contact lens solution.

Getting to grips with the complexity of disease proteins

Drug molecules seldom act simply on one protein but on protein complexes and networks. A deeper understanding of these 'cooperative assemblies' should lead to better targeting of drugs.

Sun-damaged skin responds well to laser treatment

Researchers at the University of Michigan Health System Department of Dermatology have found scientific evidence that the appearance of sun-damaged skin may be improved by treatment with a topical product that increases the skin's sensitivity to light, followed by laser therapy.

Targeted cell delivery to the cervical spinal cord is a promising strategy to slow loss of motor neurons in ALS

In a disease like ALS - one that's always fatal and that has a long history of research-resistant biology - finding a proof of principle in animal models is significant.
