Preliminary study finds holographic imaging system promising for cancer treatment planning

...can display images of the body revealing the exact location of tumors in true 3D space. A study led by Rush...a flat screen display. According to the study, the location and size of over or under-dosed regions were also easier to identify on Perspecta. The reviewers rep...

Fight weeds with plant pathogens

...l approach uses a pathogen imported from a foreign location to control a native or naturalized weed with minimal technological manipulations. "Classical biological control using imported pathogens has an overall success rate of 57 percent and has been just as successful as the use of imported insects, with...

Hundreds of thousands of viral species present in the world's oceans

...lso investigated how similar the viromes from each location were--in fact, the differences were mostly explained by variations in relative abundance of the viral species, and supports the notion that although everything is everywhere, the environment selects. Overall, they saw that samples from the British...

How the brain weaves a memory

...ions of the brain involved in processing color and location were active during formation of memories for those features. However, importantly, they found that the subjects' successful retrieval of both features--versus only color or location--was uniquely associated with enhanced activity in yet another bra...

Robotic whiskers can sense three-dimensional environment

...the bending of the whiskers and thus determine the location of different points on the head. A computer program then "connects the dots" to create a three-dimensional representation of the object. The researchers also showed that a slightly different whisker array -- one in which the whiskers were widened ...

Train your brain to hear your friends at a party

...he end of the period were as good at detecting the location of the sounds as they were before being fitted with an earplug. Something in their brain was changing or adapting to the new situation and they were learning to compensate for the hearing loss. Irving said: "When we switch on a bright light our...

RNA map provides first comprehensive understanding of alternative splicing

... Nature, shows for the first time how the specific location of short snippets of RNA affects the way that alte...here the binding clusters locate. Furthermore, the location of the peaks correlated with Nova's action on regulating whether the alternative exon is spliced in ...

Memories: It's all in the packaging, scientists say

...ring learning. If the subject later remembered the location of the word, activity was seen in an area associated with spatial processing. But if the subject remembered the word, the color and the location, then another critical brain region became involved. The researchers observed enhanced activity in the in...

Fast-freeze snapshot yields new picture of nerve-muscle junction

...xation technique that reveals new details of their location and function in neuromuscular synapses. The technique was used with tiny, one-millimeter-long nematode worms, a lab animal widely studied by neuroscientists. Investigators report the finding in the Aug. 2 issue of the Journal of Neuroscience. Janet ...

Genetic surprise confirms neglected 70-year-old evolutionary hypothesis

...ion that parts of chromosomes that switch from one location to another might cause a species to split into two different species," says John Paul Masly, lead author of the paper and doctoral student at the University of Rochester. "Showing that it was more than an academic idea was difficult, and required a b...

Rescuing injured hearts by enhancing regeneration

...or growth, and thus you have to limit the time and location of treatment," Engel adds. One possibility is to inject smaller doses of the agents into the damaged area of the heart in gel form, or instill them through a catheter, so that they would remain in the heart and be released slowly over time. Engel...

Sandia researchers discover way to see how a drug attaches to a cell

...n be imaged with electron microscopy to reveal the location of the drug receptor molecules on the cell," Shelnutt says. "This type of nanotagging technique might be used in non-biological applications as well - such as finding flaws in semiconductor surfaces." ...

Leading reason for corneal transplants comes into focus

The biggest bug in gut discomfort

Exposure to dioxins influences male reproductive system, study of Vietnam veterans concludes

...condition where the testes are not in their normal location in the scrotum) and hypospadias (abnormality of the urethra). The reason for this increase is not known, but it is thought that these disorders might be caused by environmental chemicals that are estrogenic and have endocrine-disrupting effects, ...

Beyond the book: Software automates access to brain atlases

...egrate them with atlas pages, once the exact brain location of the section has been recognized. To do this, she superimposes her research images on top of the appropriate atlas page and then saves the superimposition as a copy. So far, the only users have been researchers in Swanson's lab, says Burns, but h...

Twenty Years of Malaria Research: Outcomes and Perspectives

...ren. The unit was forced to move to its current location in Mae Sot in 1996 one year after an attack by guerrillas from the Democratic Karen Buddhist Army, targeting foreign aid workers in an attempt to force the refugees to return to Burma. During the attack, Professor Nosten and his colleague Rose McGrea...

Study finds the air rich with bacteria

...tate or country?" The team also determined that location was not as strong a source of microbial variation as time and weather. Specifically, the time of the year during the 17-week testing period was the most significant source of variation, followed by atmospheric conditions. For example, warmer and drye...

Humpback whales have brain cells also found in humans

...renia. Spindle neurons were also found in the same location in toothed whales with the largest brains, which suggests that they may be related to brain size. The authors note that spindle neurons probably first appeared in the common ancestor of hominids about 15 million years ago, since they are observed ...
