Botanical taxonomy, which extends to include the formal scientific naming of all plants, algae and fungi has gone through a landmark change in the procedure scientists need to follow when they describe new species. Details of the forthcoming changes to the newly-named 'International Code of Nomenclature for algae, fungi and plants' are laid out by Dr Sandra Knapp and colleagues in an article published in BioMed Central's open access journal BMC Evolutionary Biology. It has been suggested that...

Loud noise, especially repeated loud noise, is known to cause irreversible damage to the hair cells inside the cochlea and eventually lead to deafness. In mammals this is irreversible, however both birds and fish are able to re-grow the damaged hair cells and restore hearing. New research published in BioMed Central's open access journal BMC Neuroscience shows that growth hormone is involved in this regeneration in zebrafish. Researchers from Western Kentucky University and the University...

Black bears hibernate, sleeping their way through winter, and who can blame them? But science is only just beginning to understand the physiological changes that allow bears to re-emerge in spring without much muscle and bone loss, and how they escape from danger during the colder months. New research published in BioMed Central's open access journal BMC Physiology used cardiac monitors and radio collars to measure the year round changes in heart rate and activity of wild black bears....

Thousands of tonnes of toxic mercury are released into the environment every year. Much of this collects in sediment where it is converted into toxic methyl mercury, and enters the food chain ending up in the fish we eat. New research, published in BioMed Central's open access journal BMC Biotechnology, showcases genetically engineered bacteria which are not only able to withstand high levels of mercury but are also able to mop up mercury from their surroundings. These mercury-resistant...

European legislation restricts animal testing within the pharmaceutical and cosmetic industries and companies are increasingly looking at alternative systems to ensure that their products are safe to use. Research published in BioMed Central's open access journal BMC Genomics demonstrates that the response of laboratory grown human cells can now be used to classify chemicals as sensitizing, or non-sensitizing, and can even predict the strength of allergic response, so providing an alternative...

Mathematical modeling of infectious diseases is an important tool in the understanding and prediction of epidemics. Knowledge of social interactions is used to understand how infectious diseases spread through populations and how to control epidemics. New research published in BMC Medicine shows that a model, which included dynamic information about the heterogeneity of contact length and rate of making new contacts, was as effective as a more complex model which included the order of...

Lungless salamanders (Ensatina eschscholtzii) live in a horseshoe-shape region in California (a 'ring') which circles around the central valley. The species is an example of evolution in action because, while neighboring populations may be able to breed, the two populations at the ends of the arms of the horseshoe are effectively unable to reproduce. New research published in BioMed Central's open access journal BMC Evolutionary Biology showed that this reproductive isolation was driven by...

Neurofibromatosis (NF1) is a genetic condition which affects one in every 3,000 people. The severity of symptoms can range from benign 'caf© au lait' patches on the skin, through small tumors under the skin and deep plexiform neurofibromas, to malignant tumors of the nerve sheath. New research published in BioMed Central's open access journal BMC Medicine shows that a simple blood test for the protein melanoma-inhibitory activity (MIA) could be used to indicate the presence of...

The technology that allows scientists to profile the entire genome of individual tumors offers new hope for discovering ways to select the best treatment for each patient's particular type of cancer. However, these profiles produce huge amounts of data, and the volume alone creates unique analytical problems. In a study published on-line this week in the journal BMC Medical Genomics, researchers from Huntsman Cancer Institute (HCI) at the University of Utah describe a new analytical approach...

Synthetic collagen has a wide range of applications in reconstructive and cosmetic surgery and in the food industry. For proper function in animals a certain number of prolines within the protein need to be hydroxylated. BioMed Central's open access journal BMC Biotechnology reports that for the first time the ÃŽ±1 chain of type 1 collagen has been produced in maize with similar levels of proline hydroxylation to human collagen. Most collagen used is derived from animals...


Word of the Day
conjunto
  • A style of popular dance music originating along the border between Texas and Mexico, characterized by the use of accordion, drums, and 12-string bass guitar and traditionally based on polka, waltz, and bolero rhythms.
