One species, many genomes

...dds "The insight that the DNA sequence of a single individual is by far not sufficient to understand the genetic potential of a species also fuels current efforts in human genetics." Still, it is surprising that Arabidopsis has such a plastic genome. In contrast to the genome of humans or many crop plants suc...

Math that powers spam filters used to understand how brain learns to move our muscles

... subjective “opinion,” that measures a “learner’s” individual degree of belief in a particular outcome when that outcome is uncertain. The idea as applied to the workings of a brain is that each brain uses what it already knows to “predict” or “believe” that something new will happen, then uses that information...

New study reports hotel guests at risk from carbon monoxide poisoning

...e risk of CO poisoning from a one-night stay to an individual guest is small, the accumulated lifetime risk to individuals who travel frequently would be higher. This risk could approach zero with effective CO prevention measures.” The authors contacted 43 sites where CO poisonings had occurred and found th...

The insect vector always bites twice

... separated then put into contact with the serum of individual subjects, infected or uninfected, exposed to bites. Comparison of salivary protein immunogenic profiles obtained showed that they differ depending on the infection status of the subjects (exposed uninfected/infected) and the vector or non-vector stat...

Research team identifies new Alzheimer's gene

..., the most significant gene found to predispose an individual to late onset Alzheimer’s (LOAD) has been APOE4. In this latest study, researchers from seven organizations contributed to the genome-wide scan using Affymetrix microarray technology. The team screened the DNA from 1,400 individuals who had been clin...

Longer treatment benefits sleep apnea patients

...imized after 7.5 hours of use each night. Although individual patient response to CPAP therapy can vary, these latest findings provide a yardstick to help clinicians assess whether a patient's use is optimal....

New study finds genetically engineered crops could play a role in sustainable agriculture

...sis of large quantities of existing data from many individual experiments can provide a greater understanding of a complex issue. The project is enhanced by the creation of a public database, Nontarget Effects of Bt Crops, developed by NCEAS ecoinformatics expert, Jim Regetz, that will allow other scientists t...

Researchers examine carbon capture and storage to combat global warming

...the potential to reduce more than 90 percent of an individual plant's carbon emissions, said Lynn Orr, director of GCEP and professor of energy resources engineering. Stationary facilities that burn fossil fuels-such as power plants or cement factories-would be candidates for the technology, he said. Capturi...

Undergraduate research shows leaderless honeybee organizing

... of the colony’s older workers, not by the queen’s individual decision. What Pierce and colleagues found was that older workers gave signals to the queen and to the rest of the colony that it was time to swarm and leave the hive. Later, they were able to observe inside the swarm itself and see workers give t...

Researchers reveal structure of protein altered in autism

...organization at the molecular level. “Normally, individual neuroligins are encoded to interact with specific neurexin partners. The two partners are members of distinct families of proteins involved in synaptic adhesions, imparting ‘stickiness’ that enables them to associate so that synapses form and have t...

Exploring the dark matter of the genome

...the genome. We're pretty good at understanding how individual genes work, but we don't understand, for example, how the large-scale structure of genomes affects cellular processes. We hear too much about the 'post-genomic era' -- it's underappreciated that we don't understand the genome yet." Celniker agree...

Runners -- Let thirst be your guide

...ts Medicine paper that since 1985, “well over 100 individual cases” of EAH have been reported from physical exercise activities as diverse as forced military marches, prolonged hiking and marathon, ultramarathon and triathlon races, and there have been at least 8 documented fatalities. Some people have been kn...

Mutating the entire genome

...d in detail – scientists can identify locations in individual mice where the jumping genes have carried pieces of loxP DNA. Then, they can select a mouse with loxP on both sides of the large piece of DNA they want to mutate and study. If the jumping gene carrying loxP hops into the middle of a gene, then th...

Researchers discover 'acquired' DNA key to certain bacterial infection

... process. “We still don’t know what most of the individual genes do,” he said, “and none of the DNA sequences match those in known databases.” The researchers did discover that one of the genes provides coding for a protein that targets action in the host cell, which may help the bacterium survive in the ...

Turn-ons and turn-offs for neurons

... Heidelberg have therefore systematically examined individual components of the Tet systems and delineated the necessary conditions for reversible control of gene expression in neurons. In the June 20th issue of the online, open-access journal PLoS ONE, they report that genes which had been inactive in neuro...

Male circumcision overstated as prevention tool against AIDS

When this artificial weighting was removed Talbott found that circumcision was no longer statistically significant in explaining the variance in AIDS infection rates across the countries of the World. Second, to dat...
