The shape of things to come: Morphology database going global

...d can reduce both the amount of disk space on each machine and the cost to any one institution. Although scientists will be the only ones to have access to the system to deposit, retrieve or comment on items, the system is free and may be viewed by anyone. "Everyone from kindergartners to the top researche...

Applying ecological laws to bacteria

...rmine those of microbial communities. Engineering machine metal-cutting fluid reservoirs are used as coolants and lubricants in metal machining processes. The reservoirs of the machines studied, such as lathes and mills, were of increasing size and were said to be analogous to an archipelago of islands. Mi...

Carnegie Mellon cyLab researchers work to develop new red tide monitoring

...dly growing field, which includes inverse physics, machine learning and human-computer interaction," Cai said. ...

New bioinformatics technique for systematically analyzing key regions in DNA that help control gene activity

... "To accomplish this," Komorowski said, "we used a machine learning technique called rough sets to mathematically model general rules that could associate known binding sites and gene expression in yeast, which is one of the most widely studied organisms." From the analysis of gene activity under a variety o...

Rensselaer researchers develop approach that predicts protein separation behavior

...ric mass action isotherm models and support vector machine regression computations. Biotechnology and Interdisciplinary Studies at Rensselaer At Rensselaer, faculty and students in diverse academic and research disciplines are collaborating at the intersection of the life sciences and engineering to enc...

Fluorescing lab worms signal longer life spans

...nly six such instruments in the United States, the machine can sort about 30 worms per second, Johnson said. Genetic testing on both the bright and dim worms revealed that the levels of the green fluorescent protein expressed by parent worms were not passed down to offspring and therefore not heritable, sai...

Genomic sequences processed in minutes, rather than weeks

..., PNNL's supercomputer has 1,960 processors ?a big machine with lots of memory and the ability to tackle large problems. However, without special modifications, software doesn't run any faster on it than it would on a personal computer. In order to get answers to complicated biological questions more quickly...

Program finds lost genes in nematode genome

...rn a lot of computer power, they'll come up with a machine that can beat the world champion. The same principal applies to developing a machine that can reveal the mysteries of our genes. In this case, the necessary investments have been made, ...

Breakthrough isolating embryo-quality stem cells from blood

...them stretchier than normal cells. Käs and Guck's machine uses a powerful beam of infrared laser light to stretch and measure cells one by one. His optical stretcher differs from an existing tool known as optical tweezers in which the light is focused to a sharp point to grab hold of a cell. In contrast, th...

Confocal imaging promises early detection of skin cancer

...sts by a factor of ten, resulting in a 20,000-euro machine that is affordable for many outpatient centres.?/p> Trials at two university hospitals ?in Regensburg, Germany, with experienced dermatologists, and in Brescia, Italy, with people who were not experts in the field ?proved the principle of confoca...

Taking the piste out of Alpine vegetation

Researchers make gains in understanding antibiotic resistance

...nit of the ribosome. The ribosome is the molecular machine responsible for translating the genetic information on messenger RNA into the long strings of amino acids called polypeptides that are used to build the cell's enzymatic machinery. "These antibiotics are clinically very important, and resistance to ...

Weill Cornell Research Reveals Secrets Of Trafficking Within Cells

...rain synapses, we've learned that endocytosis is a machine that really runs quite fast, and in this latest study we were trying to figure out what those speed limits are, especially with regard to varying amounts of clathrin," Dr. Ryan explained. However, they faced one methodological roadblock. As Dr. Rya...

Molecular machine may lead to new drugs to combat human diseases

The crystallized form of a molecular machine that can cut and paste genetic material is revealing possible new paths for treating diseases such as some forms of cancer and opportunistic infections that plague HIV patients. Purdue University researchers froze one of these molecular machines, wh...

Plants, animals share molecular growth mechanisms

...s Actin Related Protein 2/3 (ARP2/3) is a cellular machine that controls formation of actin filaments, which are important for cell growth and movement. Actin filaments organize the inside of the cell and allow it to grow, and they determine where certain structures in a cell are positioned and how plants re...

New, automated tool successfully classifies and relates proteins in unprecedented way

...," saidMurphy, a professor of biological sciences, machine learning, andbiomedical engineering. "This work should provide a more thoroughunderstanding of cellular processes that underlie disease."Using this approach to spot a protein cluster could help scientistsidentify a common protein structure that enabl...
