Allen Institute for Brain Science leads international effort to advance analysis of single neurons

The Allen Institute for Brain Science is spearheading a landmark international effort to define and advance the state-of-the-art digital reconstruction and analysis of single neurons. The project launching today, called BigNeuron, aims to create reliable high-throughput and quantitative 3D reconstructions of the thousands of branches that make up individual neurons: a crucial step to ultimately understanding how the brain encodes information.

IU researchers awarded NIH grant to develop new weapon to fight against antibiotic-resistant bacteria

The alarming increase of antibiotic-resistant bacteria poses health and economic threats worldwide, with more than 2 million Americans infected by the bacteria each year. Now, a team of Indiana University chemists and biologists has been awarded a major grant to develop and use a chemical tagging method to better understand how bacteria build their cell wall, which is still the best target for new antibiotics.

Modelling the biological mesoscale: an interview with Professor Art Olson

The biological mesoscale range includes biological structures that range from 10 to 100 nanometers (billionths of a meter). Structures in this size range include viruses, cellular organelles, large molecular complexes, and any other internal cellular environments within that range.

TSRI study points way to potential therapies for hereditary spastic paraplegia

Scientists at The Scripps Research Institute have discovered that a gene mutation linked to hereditary spastic paraplegia, a disabling neurological disorder, interferes with the normal breakdown of triglyceride fat molecules in the brain. The TSRI researchers found large droplets of triglycerides within the neurons of mice modeling the disease.

Biomarkers help resolve differential diagnosis between MPM and non-cancerous pleural tissue

Scientists have identified four biomarkers that may help resolve the difficult differential diagnosis between malignant pleural mesothelioma (MPM) and non-cancerous pleural tissue with reactive mesothelial proliferations (RMPs).

Female mice deprived of dietary zinc before conception experience fertility problems

Female mice deprived of dietary zinc for a relatively short time before conception experienced fertility and pregnancy problems and had smaller, less-developed fetuses than mice that ingested zinc during the same times, according to researchers in Penn State's College of Agricultural Sciences.

New study investigates lasers used for urological surgery

Neither the total nor the core diameters of laser fibers correspond to the advertised laser fiber diameter, revealed a new study investigating lasers used for urological surgery. Furthermore, there are serious differences between manufacturers of fibers with a supposedly equal diameter.

New antibodies estimate risk of polyps developing into bowel cancer

Polyps in the mucosa of the colon are a common finding during screening colonoscopies. Some sub-groups of polyps are classed as precursors of bowel cancer. Until now, it has not been possible to precisely estimate the risk of these polyps developing into bowel cancer.

Scientists reveal new images of how white blood immune cells attack tumours, viral infections

Scientists from The University of Manchester have revealed new images which provide the clearest picture yet of how white blood immune cells attack viral infections and tumours.

Viral load: A new technique that helps doctors diagnose chronic viral diseases

To test the severity of a viral infection, clinicians try to gauge how many viruses are packed into a certain volume of blood or other bodily fluid. This measurement, called viral load, helps doctors diagnose or monitor chronic viral diseases such as HIV/AIDS and hepatitis.

New evidence-based guideline for using WSI systems for diagnostic work

The College of American Pathologists released today a new evidence-based guideline, "Validating Whole Slide Imaging for Diagnostic Purposes in Pathology." The guideline is the first of its kind and is now available in the CAP's peer-reviewed journal, Archives of Pathology & Laboratory Medicine.

TB testing: today as good as 2-day

Same-day sputum smear microscopy is as effective as standard smear microscopy for the detection of pulmonary tuberculosis, according to a review commissioned by the World Health Organization.

New method gives precise picture of how immune system works

Chronic infections are a large and growing problem throughout the developed world, and intensive research is being conducted in ways to combat the recalcitrant bacteria. When bacteria aggregate into so-called biofilm, they become resistant to antibiotics. Until now scientists have only been able to speculate about what happens when bacteria overpower the immune system during a chronic infection.

Initial data to construct first whole-brain wiring diagram of vertebrate brain

Neuroscientists at Cold Spring Harbor Laboratory (CSHL) reached an important milestone today, publicly releasing the first installment out of 500 terabytes of data so far collected in their pathbreaking project to construct the first whole-brain wiring diagram of a vertebrate brain, that of the mouse.

RUB researchers gain new insights into mechanisms of cardiovascular disease

Malformed desmin proteins aggregate with intact proteins of the same kind, thereby triggering skeletal and cardiac muscle diseases, the desminopathies. This was discovered by researchers from the RUB Heart and Diabetes Center NRW in Bad Oeynhausen led by PD Dr. Hendrik Milting in an interdisciplinary research project with colleagues from the universities in Karlsruhe, Würzburg and Bielefeld. They report in the Journal of Biological Chemistry.

Brain mitochondria are dysfunctional in early-stage Alzheimer's

Mitochondria -- subunits inside cells that produce energy -- have long been thought to play a role in Alzheimer's disease. Now Mayo Clinic researchers using genetic mouse models have discovered that mitochondria in the brain are dysfunctional early in the disease.
