Oxygen triggered the evolution of complex life forms
Oxygen played a key role in the evolution of complex organisms, according to new research published in BMC Evolutionary Biology. The study shows that the complexity of life forms increased earlier than was thought, and in parallel with the availability of oxygen as an energy source. In the largest study to date that does not focus on vertebrates,... view more... (2004-01-22)
New insect on Balearic Islands
After 10 years of biochemical and molecular analysis of the Tyrrhenoleuctra plecoptera that live in the Western Mediterranean, Spanish and Italian scientists have now demonstrated that one of the insect populations of this group is a distinct and, therefore, new species. view more (2009-07-16)
Social habits of cells may hold key to fighting diseases
Scientists in Manchester are working to change the social habits of living cells - an innovation that could bring about cleaner and greener fuel and help fight diseases such as cancer and diabetes. view more (2007-08-27)
Virginia Tech chemists create new polymers by adding DNA base pairs

PET accurately identifies esophageal cancer patients' positive responses to chemotherapy
Early metabolic imaging with positron emission tomography (PET) accurately identifies patients responding to chemotherapy for esophageal cancer, noted German researchers at the 54th Annual Meeting of SNM, the world's largest society for molecular imaging and nuclear medicine professionals. view more (2007-06-04)
Mechanism related to the onset of various genetic diseases revealed
Researchers at the Department of Biochemistry and Molecular Biology of Universitat Autònoma de Barcelona (UAB) have revealed the process by which proteins with a tendency to cause conformational diseases such as amyotrophic lateral sclerosis, familial amyloidotic polyneuropathy, familial amyloidotic cardiomyopathy, etc. finally end up... view more...

Teachers Fear Biology Fieldwork is Heading for Extinction
Biology fieldwork could be heading for extinction says a report to be published on Friday 18th October by the Field Studies Council and the British Ecological Society. This loss of opportunity will rob young people of the personal benefits of out of school experiences, as well as the educational value of such trips. Dr Susan Barker, Lecturer at... view more...

Research identifies 3-D structure of key nuclear pore building block
The genome of complex organisms is stashed away inside each cell's nucleus, a little like a sovereign shielded from the threatening world outside. view more (2009-06-08)
Rebuilding the evolutionary history of HIV-1 unravels a complex loop
An essential component of the human immunodeficiency virus (HIV-1) molecular machinery responsible for infecting cells consists of functionally-specialized layers, according to a study by investigators at the University of California San Diego (UCSD) Antiviral Research Center (AVRC), published November 23 in PLoS Computational Biology. view more (2007-11-26)
Groundbreaking study on complex movements of enzymes
A groundbreaking study has revealed in great detail how enzymes in the cell cooperate to make fat. These enzymes are integrated into a single molecular complex known as fatty acid synthase. This complex is regarded as a potential target for developing new anti-obesity and anti-cancer drugs. view more (2009-02-12)
The closest look ever at native human tissue
Seeing proteins in their natural environment and interactions inside cells has been a long-standing goal. Using an advanced microscopy technique called cryo-electron tomography, researchers from the European Molecular Biology Laboratory [EMBL] have visualised proteins responsible for cell-cell contacts for the first time. view more (2007-12-06)
Gene duplication allowed pigs to have more babies
With increasing numbers of whole genomes being sequenced, researchers are keen to analyse the functions of the genes they contain and the proteins these genes encode. Yet, according to researchers writing in BMC Biology, to fully understand any genome, researchers must use palaeontology, geology and chemistry to help them discover the reasons why... view more...

Researchers shed more light on conversion of water to hydrogen gas
Chemists are several steps closer to teasing hydrogen fuel from water using man-made molecular devices that collect electrons and use them to split hydrogen from oxygen. view more (2005-08-29)
Clawed frog helps Fanconi anemia research make leaps
