Researchers track how spores break out of dormant state

...ith unprecedented resolution how the new bacterium emerges from the disintegrating spore. The new research, led by Lawrence Livermore National Laboratory scientists, appears in the May 28-June 1 early online edition of the Proceedings of the National Academy of Sciences. The research appears in this week’s (...

Philandering female felines forgo fidelity

...ompass several female ranges. “The picture that emerges is that of wide-ranging females mating with a number of males, which could be an advantage in terms of helping to maintain genetic diversity,” said ZSL’s Dada Gottelli, the study’s lead author. Findings from the study are significant for conservat...

Will the plague pathogen become resistant to antibiotics?

..., we warned that if this type of strain spreads or emerges again, it would pose a serious health problem" says co-author Elisabeth Carniel, head of the Yersinia Research Unit at the Institut Pasteur in Paris. "The discovery that the multiresistance plasmid acquired by the plague bacillus is widespread in env...

Power emerges from consensus in monkey social networks

...nformation theory, the researchers show that power emerges through consensus. There is a high degree of consensus among group members that an individual is powerful if that individual has received multiple subordination signals from many individuals ?in the case of pigtailed macaque monkeys, a silent bared-t...

Math model predicts cancer behavior

...tional models like this, in which complex behavior emerges from computer simulations grounded in understanding phenomena at a smaller scale, have been a staple of chemistry, physics, and related engineering disciplines for a long time." Quaranta and Cummings expect to see this new way of thinking sweep thr...

Mass vaccination unnecessary in the event of a large bioterrorist US smallpox attack

...t people may or may not be contagious. Then a rash emerges all over the body and grows increasingly severe over the next 20 or so days, eventually forming scabs; during this period people are contagious, particularly during the first seven to 10 days of the rash. The disease eventually resolves and contagion...

Boston University biomedical engineers win major grant for pursuit of the '$1,000 Genome'

...hers to record the sequence of bases as the strand emerges from the nanopore. Meller has devised a system of lasers and highly sensitive detectors which greatly increase the process' resolution. He is the only researcher in the world using this method, which he names "Opti-Pore." Weng's involvement centers...

Five new technologies that promise to transform medicine

...weight patient simply walks through the device and emerges several pounds lighter. No side effects are seen apart from the resizing of his wardrobe. Patients with chronic diseases who need regular medication will benefit from a miniature implant that monitors and transmits data on heart and breathing rate...

Study shows how herpes infects cornea, evades immune cells

...d, the envelope containing the herpes virus genome emerges from the sac undamaged and able to infect the cell. "This raises the interesting possibility that herpes may be able to evade the immune system defenses in the same way," he said. "Understanding herpes' unusual pathway for infecting the stroma cells...

Ozone recovering, but unlikely to stabilize at pre-1980 levels, says study

...of how brassinosteroids stimulate plant growth now emerges based on those experiments: steroid hormones are still thought to inactivate BIN2 and reciprocally activate BES1, but instead of freeing BES1 to shuttle into the nucleus, it is now clear that the crucial activation step occurs in the nucleus where BE...

Salk scientists untangle steroid hormone signaling in plants

Tandem transcripts team together

... understanding of the eukaryotic genome, a picture emerges that challenges this paradigm ?not a picture in which the sequences in the genome have distinct functions, but rather one in which the sequences participate in multiple transcripts, encoding molecules with diverse functionality." Sorek's team system...

Genomics-based vaccine could prevent deadly cattle disease

...munity to the parasite, and thus East Coast fever, emerges from immune system cells known as killer T cells. Second, they know that T. parva is an intracellular pathogen--it infects and secretes proteins inside cattle white blood cells, which become malignant. The white blood cell then unwittingly passes s...

Watching the brain switch off 'self'

...the outside world. "To conclude, the picture that emerges from the present results is that, during intense perceptual engagement, all neuronal resources are focused on sensory cortex, and the distracting self-related cortex is inactive. Thus, the term "losing yourself" receives here a clear neuronal correla...

Sweetgum tree could help lessen shortage of bird flu drug

...he fruit, Poon says. In the mature tree, the fruit emerges as a green seedpod that later dries into a brown, spiny husk, which releases an abundance of tiny, grain-like seeds. To optimize shikimic acid extraction, the gumballs need to be harvested when they are still green and before the seeds have been disp...

Infants can organise visual information at just four months

.... The results showed that grouping by brightness emerges first: it was observed at two months, in line with previous observations that this ability is present in newborn babies. At four months, two further grouping abilities emerged: grouping by shape and by proximity. Proximity grouping had not been teste...

Complex gene interactions account for autism risk

...h the behavior and the pattern of cell damage that emerges in autism," said John Hussman, Ph.D., a study co-author and president of The Hussman Foundation, one of the groups that funded the study. The researchers examined 14 genes that encode portions of the GABA receptor in 470 Caucasian families. Of those...

UW scientists report a new method to speed bird flu vaccine production

...." When a new strain of highly virulent influenza emerges to infect humans, vaccine makers must tailor their vaccines to match it because, genetically, the virus is always different. The process is a race against time and can take months depending on how quickly new strains are identified, genetically disar...

Insects, viruses could hold key for better human teamwork in disasters

...ect for a given situation and the group's behavior emerges from such interactions, these models may be useful in understanding the basic principles and best practices to be considered when developing strategies that will coordinate knowledge sharing in chaotic social settings where a small set of rules appli...
