Gold nanoparticles prove to be hot stuff

...elp study them, according to scientists at JILA, a joint institute of the National Institute of Standards and Technology (NIST) and University of Colorado at Boulder. Biophysicists often study nanoscale and even picoscale mechanics by using lasers to both apply force to and track the position of fragile b...

New findings could lead to vaccine for severe malaria

...ia hits pregnant women and children the hardest. A joint study between Karolinska Institutet in Sweden and Makerere University in Uganda has now produced some important findings on how the malaria parasite conceals itself in the placenta. Plasmodium falciparium is the name of by far the most virulent of t...

Study shows antibiotic-resistant bacteria responsible for increase in muscle infections

...ons as well as invasive infections such as bone or joint infections or pneumonia. Failure by physicians to suspect this kind of drug-resistant staph can lead to treatment with the wrong antibiotic. Pyomyositis is an acute bacterial infection of skeletal muscle that produces an abscess within the muscle. M...

How nature tinkers with the cellular clock

... is a strategy that is conserved," says Peer Bork, joint coordinator of EMBL's Structural and Computational Biology Unit, "but details of which genes are regulated in this way and the exact timing of their expression have changed a lot throughout evolution. What is really surprising is the speed at which t...

Gene linked to rare disease activates fat breakdown

...S fail to activate ATGL, they found. Moreover, the joint expression of CGI-58 and ATGL limits lipid accumulation in cultured cells, while treatments that block CGI-58 in fat cells inhibit the removal of stored triglycerides. Finally, the addition of normal CGI-58 in cells having the CDS mutation restores l...

Precision biochemistry tracks DNA damage in fish

...DNA damage in the gills of English sole. In a new joint paper, the researchers report on several biomarkers, including pollution-induced P450 enzyme changes, and on infrared spectral analysis of DNA and measurements of specific modifications to DNA from fish gills and livers using liquid and gas chromatog...

For example, when imaging a joint like the knee - Block's inspiration for developing the new technique - suppressing the fat signal in bone provides image contrast between bone and the cartilage surface. The conventional data-acquisition method would spend half its scan time suppress...

New genes implicated in rheumatoid arthritis

... rheumatoid arthritis (RA), a chronic inflammatory joint disease. While its specific cause is not yet known, RA has been linked to an inherited susceptibility. Interestingly, despite its strong genetic component, RA's occurrence among siblings seems to be random. In the quest to identify disease-speci...
