North & South American researchers find architectural abnormalities in T. cruzi ribosome

...pioneered the analysis of ribosome structures by a method he developed for three-dimensional reconstruction of large molecules using electron microscopy and image processing. Levin told him the story of Chagas and the need to know more about the structure of the parasite's ribosome. A ribosome is basically...

Most embryos produced during IVF do not result in live births

...is a difficult task unless they can come up with a method in the lab to identify the best embryos. "Some potential methods for screening embryos include using pre-implantation genetic diagnosis and biochemical markers of embryo viability," said Patrizio. "In addition this study should also move the field t...

Immune system has evolved to prevent autoimmune disease

... proteins in a healthy cell. The mutation response method employed by our adaptive immune system seems keyed to this number, producing antibodies that are statistically likely to mistakenly bond with healthy proteins slightly less than one in a trillion times, meaning that on average, they recognize only in...

NHGRI expands effort to revolutionize sequencing technologies

...m sequencing by synthesis reaction chemistry. This method allows for smaller volumes of materials to be used...This group will develop and implement an efficient method capable of sequencing mammalian size genomes by amplifying single template molecules, and subjecting...

UNC scientists discover new role for protein as fundamental inhibitor of cell movement

...ration and PAK1 activation, the authors used a new method known as RNAi or RNA interference to knock down or reduce CIB1 expression in various cell lines. Cells with less CIB1 had less PAK1 activation and migrated faster. The authors also showed that the more CIB1 these cells had, the less likely they were ...

Scientists discover new way to look at how molecules twist and turn on water

...al of Physical Chemistry B . "We have developed a method to determine the tilt and twist angles of these molecules at the surface, a characterization that is important for understanding how they might function in various practical applications," Richmond said. "This is a general approach that has broad imp...

With millions of animal species on Earth, DNA barcoding can be a helpful identification tool for ecologists who may not necessarily be taxonomy experts, he said. "This new technology is s...

Climate change will affect carbon sequestration in oceans, model shows
