The bumps, which ranged in size from 11 nanometers to 100 nanometers, were a normal result of the chemical process that sh...Scientists identify new vaccine targets for cancer-causing strains of human papilloma virus

Currently, CIN is detected by PAP smear and treated by surgical removal of the pre-cancerous lesions, a costly procedure that may result in reproductive complications and requires continual post-surgery monitoring for recurrence.

...arboreal mammals," said Dr Hornsby. Other species detected by the sampling methods included the native yellow-footed antechinus, bush rat and ring-tailed possum, while introduced black rats were also common. The detection of these other species showed that Dr Hornsby was using effective techniques. These wer...... also supports receptors tuned to unique odors not detected by the partner. With this partially overlapping detection system, the nerve pairs can sense more odors than would be possible if they had identical receptors or even if each were tuned to completely different smells, the scientists found.

Peterson and colleagues used new mass spectrometer techniques to improve sensitivity and reduce the cost to less than $10.
