Scientists develop new color-coded test for protein folding

... will eventually be useful for testing other, more complicated proteins," Zare said, noting that a gold nanoparticle sensor could turn out to be a quick and inexpensive way for doctors to identify antibodies and other signs of infection in the blood stream. Over the next few months, he and his colleagues plan to...

Yale researchers identify molecule for detecting parasitic infection in humans

...ma gondii (T. gondii) causing toxoplasmosis, has a complicated life cycle in which it is transmitted from mice to cats and then to humans. Previous research had shown that T. gondii is recognized by a TLR and that the recognition of this parasite is crucial for an appropriate immune response. However, it was unc...

Key mechanism in genetic inheritance during cell division identified

...ex. While the authors say that ring formation is a complicated way to construct a microtubule binding structure, a microtubule binding ring might be uniquely suited to fulfill the functions of the Dam1 complex. In comparison with the purified Dam1, the Dam1 mutants produced partially formed rings that reduced mi...

Marburg haemorrhagic fever in Angola update

...further spread. Such straightforward measures are complicated by the distinct features of this disease. The sudden onset, dramatic symptoms, and rapid deterioration of patients, and the absence of a vaccine and effective treatment, invariably incite great anxiety in affected populations. This anxiety, in turn, ...

Researchers unlock mechanism creating jigsaw puzzle-like plant cells

...pposing Action on Cell Morphogenesis," explained a complicated and coordinated series of chemical interactions in a group of cellular proteins, known as GTPases (guanosine triphosphatases) that act as molecular switches, which regulate how plant cells grow into interlocking patterns resembling jigsaw puzzle piec...

Scientists journey to southern Africa to unravel the secret world of elephant communication

...arch for a mate in this vast wilderness is further complicated by the elephant's reproductive biology. Females breed when they are in estrus--a brief period of ovulation that only occurs every two years and lasts just a few days. "Females in estrus make these very low, long calls that bulls home in on because i...

New project aims to make large-scale lobster farms feasible

...wild. The lobster larval growth cycle is extremely complicated and as yet reproduction and growth to adulthood has not been accomplished in captivity in reliable numbers. Development of collection methods to get enough larvae to support large-scale commercial culture has so far not been possible, but in 2003 te...

Scripps scientists find potential for catastrophic shifts in Pacific ecosystems

...Rather, these physical characteristics evolve in a complicated but apparently linear manner, involving the sum of many variables. This finding means that suspected regime-like fluctuations in the North Pacific physical system are for all practical purposes wiggles that are best modeled by traditional statistical...

Molecular thermometers on skin cells detect heat and camphor

... basic molecules and mechanisms that underlie this complicated communication system that is our senses, and one group of researchers from The Scripps Research Institute and the Genomics Institute of the Novartis Research Foundation (GNF), has been making headway in trying to understand those that mediate our sen...

Genomic sequences processed in minutes, rather than weeks

...on a personal computer. In order to get answers to complicated biological questions more quickly, PNNL researchers "parallelized" the software using Global Arrays, a powerful programming toolkit, by creating algorithms to divvy up the work. PNNL researchers say ScalaBLAST may be used to process complex genomic ...

Rensselaer researchers develop approach that predicts protein separation behavior

...oteins. "We intend to test the model against more complicated protein structures as part of its further development," said Breneman. "The outcome of this work will yield fundamental information about the complex relationship between a protein's structural features and its chemical binding properties, and also a...

Opiates Better Than Sedatives For Treating Newborns In Withdrawal

...n to the special care nursery unless withdrawal is complicated and that this is facilitated by use of morphine instead of phenobarbitone. This helps keep mothers and babies together, helps in educating the mothers in mothercraft skills and to recognize signs of infant withdrawal, and helps in assessment of the q...

UCSD discovery may provide novel method to generate medically useful proteins

...stem. Unlike the phage protein, antibodies have a complicated loop structure. The size of the loops varies in addition to the amino acid building blocks that constitute the antibody protein. Although this mechanism can generate more than 100 trillion different antibodies, the researchers say replicating it in...

Single gene is genetic switch for fly sexual behavior

A male fly's sexual courtship of a female fly is a complicated business of tapping, singing, wing vibration, and licking, but a single gene is all that is needed to produce this complex behavior, according to new research published in this week's issue of the journal Cell. The gene encodes the Fruitless protein...

New law for resolution allows unprecedented sharpness in fluorescence microscopy

...gher resolution, the textbook knowledge was that a complicated and costly electron or scanning tunneling microscope would be required. However, over the past few years, researchers from the Max Planck Institute for Biophysical Chemistry in Göttingen, Germany, have developed with Stimulated Emission Depletion (ST...
