CSIRO scientists join fight to save 'Tassie devil'

...d of the disease.” To date AAHL scientists have processed and examined 29 lesions from 12 affected animals and have also collected and processed a further 30 affected animals where both tumour tissue and tumours grown in the laboratory were exam...

Rising skin cancer rates are more likely to affect wealthy people, says 12-year review

... and a 62 per cent increase in skin cancer samples processed by pathology laboratories. The figures also showed that the three most common skin cancers - basal cell carcinoma, squamous cell carcinoma and malignant melanoma - accounted for 27 per cent of all male cancers and 26 per cent of all female cancers...

CT scan reveals ancient long-necked gliding reptile

...ther they were a set of thin slices that had to be processed to obtain information about the animals. Even then, no single slice contained the entire skeleton. Post-scan processing produced an amazingly clear, if somewhat flattened, image of a small reptile with a long neck and swept back wings. Gliding b...

New technique will produce a better chromosome map

...lip and slide. Only about 10 percent of the slides processed this way provide useable images and even those rarely offer crisp structural details, Novikov said. The new approach includes two components: the use of mechanical devices to spread and flatten the cells, and the application of computer-based imag...

Hybrid molecule causes cancer cells to self-destruct

...s inside the cell. Once inside the cell, ManNAc is processed into another sugar known as sialic acid that plays key roles in cancer biology, while butyrate orchestrates the expression of genes responsible for halting the uncontrolled growth of cancer cells. Although the study of the exact molecular mechani...

Common gene version optimizes thinking -- but with a possible downside

...results in more efficient filtering of information processed by the brain's executive hub, the prefrontal cortex. However, the same version was also more prevalent among people who developed schizophrenia, a severe mental illness marked by delusions, hallucinations and impaired emotion that affects one percent...

Wired for sound: How the brain senses visual illusions

... that visual and auditory stimulation might not be processed separately, then merged together, as previously assumed, but that an almost-simultaneous integration of the sensations may actually take place in the brain." The UCSD scientists measured event-related potentials (ERPs), brain responses that are di...

Scientists find new genetic clue to cause of Alzheimer's disease

...r's disease, amyloid precursor protein, or APP, is processed into amyloid beta protein fragments that make up plaques in the brain. The researchers began their search for genetic influences amid a group of proteins that transport APP within cells, looking for small changes, or "misspellings," in seven genes in...

Studies yield insight into the numerical brain

...daptation effect. Alternatively, if a brain region processed a specific nonabstract number (e.g., 8) then adaptation would only be seen for the same notation (e.g., 8 but not eight). Their analysis revealed an effect of notation in the right parietal lobe, showing that this region appears to harbor neurons t...

Do you hear what i see?

...h hearing, taste, touch, sight, and smell are each processed in distinct areas of the brain and only later integrated. The new research, led by Christoph Kayser, PhD, at the Max Planck Institute for Biological Cybernetics in Tübingen, Germany, was published in the February 21 issue of The Journal of Neuroscie...

"Thanks to a new archive of uniformly processed data from 1991 to the present day, which is due to be launched later this year, it will soon be possible to provide a definitive statement of the rate at which global temperatures have been changing and how the variability of our climate has been cha...

Scientists reveal structure of gateways to gene control

...A sequencing. "Traditional DNA sequencing methods processed one DNA strand at a time, but now we can sequence hundreds of thousands of DNA strands at once, rapidly learning incredible amounts of new information," Pugh said. The knowledge that most genes are packaged basically the same way is powerful infor...

New research shows why too much memory may be a bad thing

...he time it takes for new short-term memories to be processed and stored. Published in the Proceedings of the National Academy of Sciences (March 13, 2007 issue), the research reinforces the old adage that too much of anything ?even something good for you ?can actually be detrimental. In this case, the good th...

The 12 adults participating in the study ate two spaghetti test meals ?one included sauce made from tangerine tomatoes, while the other featured sauce made from the ...

How the brain weaves a memory

...f how this binding takes place as the memories are processed by the brain's memory center, the hippocampus. A central question has been whether the hippocampus receives an "episodic packet," or a collection of perceptual strands that it must integrate into a memory. In an article in the November 9, 2006, issu...

Analysis identified a Plasmodium (the species of parasite that causes human malaria). Chart review showed that the p...

Mysterious 'neural noise' actually primes brain for peak performance

...articulating most of the variables your brain just processed for you. Similarly, intuition may be less a burst of insight than a rough consensus among your neurons. Pouget and his team are now expanding their findings across the entire cortex, because every part of our highly developed cortex displays a simi...
