Cell-free protein synthesis is potential lifesaver Posted: 29 Dec 2015 05:41 PM PST Lives of soldiers and others injured in remote locations could be saved with a cell-free protein synthesis system, say scientists. The device uses microfabricated bioreactors to facilitate the on-demand production of therapeutic proteins for medicines and biopharmaceuticals. Making these miniature factories cell-free, which eliminates the maintenance of a living system, simplifies the process and lowers cost.

Breast cancer detection rate using ultrasound is shown to be comparable to mammography Posted: 28 Dec 2015 02:44 PM PST The use of ultrasound in detecting breast cancer has been shown to be comparable in its sensitivity to that of mammography and should be considered when testing for the disease according to a new study.

Undiagnosed Diseases Program gives answers where there were none Posted: 28 Dec 2015 01:17 PM PST An Undiagnosed Diseases Program provides an ending for one family's 24 year search for answers to their children's health issues.

Scientists detect inherited traits tied to sleep, wake, and activity cycles Posted: 28 Dec 2015 01:14 PM PST A dozen inherited traits related to sleep, wake, and activity cycles that are associated with severe bipolar disorder have been identified by an international team of researchers.

Hypnosis may provide new option for 'awake surgery' for brain cancer Posted: 28 Dec 2015 01:14 PM PST Could hypnosis help to reduce the psychological trauma associated with 'awake craniotomy' for brain cancers? A new 'hypnosedation' technique offers a new alternative for patients undergoing awake surgery for gliomas, suggests a study.

Myopia-related differences in eye structure may help in developing 'customized' intraocular lenses Posted: 28 Dec 2015 01:13 PM PST The presence of myopia, or nearsightedness, significantly affects the muscles used in focusing the lens of the eye -- a finding with important implications for the development of 'accommodating' implanted intraocular lenses (IOLs) that can adjust to different visual distances, reports a new study.

Study opens new door for ALS drug discovery Posted: 28 Dec 2015 01:12 PM PST Researchers have discovered the first-ever evidence-based description of the neuronal protein clumps thought to be important in Amyotrophic Lateral Sclerosis (ALS), also known as Lou Gehrig's disease, a fatal neurodegenerative condition. This research development could be a crucial step toward developing drugs to stop the creation of the clumps and stem the progression of the disease, they say.

Lifestyle switching: Bacillus cereus is able to resist certain antibiotic therapies Posted: 28 Dec 2015 09:47 AM PST The pathogenic bacterium Bacillus cereus causes vomiting and diarrhea as well as systemic and local infections. A team of researchers has reported for the first time that B. cereus, following contact with certain antibiotics, can switch into a special slowed-down mode. The bacteria then form small colony variants (SVCs) that are difficult to diagnose and almost impossible to treat with certain antibiotics. This discovered mechanism may provide an alternative explanation for antibiotic resistance.

Efficacy of major chlamydia drug confirmed Posted: 23 Dec 2015 07:18 PM PST In one of the most tightly controlled trials ever conducted of drugs used to treat sexually transmitted infections, researchers have confirmed that azithromycin remains effective in the treatment of urogenital chlamydia.

Ecologist finds another cause of antibiotic resistance Posted: 23 Dec 2015 07:16 PM PST One researcher is concerned that there's more to the problem of antibiotic-resistant bacteria than the misuse of common medications. A senior research ecologist, this scientist believes environmental contaminants may be partly to blame for the rise in bacterial resistance, and he tested this hypothesis in streams on the US Department of Energy's Savannah River Site.

Two Alzheimer's risk genes linked to brain atrophy, promise future blood markers Posted: 23 Dec 2015 07:16 PM PST Two genetic variants previously linked to Alzheimer's disease have been more specifically tied to brain atrophy that is characteristic of the disease. Alzheimer's disease is a progressive illness that is the leading cause of dementia and the sixth leading cause of death in the United States. There is no cure for the disease and currently available treatments can slow, but cannot stop, the deterioration.

Changing architecture: New understanding of spatial organization Posted: 23 Dec 2015 10:41 AM PST Fifteen years ago, scientists had determined the entire sequence of the genetic letters making up our DNA. But this was only a step in a long journey: in addition to the letters, information is also encoded in the packing of DNA. A team of researchers has now generated comprehensive 3-D maps of the spatial organization of the mouse genome. Such maps might help track down genes involved in hereditary diseases.
