Snake-like robot and steady-hand system could assist surgeons

...operating site. The doctor would then maneuver the controls to guide the movement of the robot. The prototype is made of nonmagnetic metals so that it can be used safely near magnetic imaging equipment. The tools' movements are nimble because sophisticated software can make up to 100 adjustments per second. ...

Brains can recover from alcoholic damage but patients should stop drinking as soon as possible

...en), matched for age and gender, were recruited as controls for the study. The data were analysed and evaluated using FSL, a sophisticated software package developed at the Oxford FMRIB Centre, and LCModel (a computer program that analyses spectroscopy data) to give estimates of changes to brain volume, form ...

Two central mysteries in genome inheritance solved at UCSD

...equired to detect attachment errors. This complex controls activation of a protein kinase called Aurora. "A major question becomes, how are bad attachments detected"" said Desai. "Our results suggest that the linkage between chromosomes and the spindle, which includes a protein kinase activator, acts a sen...

Protein 'fingerprint' in spinal fluid could spot Alzheimer's disease

"Just as the human genome reflects the array of genes a person possesses, the proteome' is the vast collection of proteins expressed by those genes," said Lee. "Essentially we used high-tech methods to contrast the proteomes of A...

Nonetheless, said Grekin, "these results are compelling and suggest that EEG asymmetry may be an index of a general vulnerability to psychopathology. Interestingly, participants with both alcoho...

Targeted cancer drugs may work by disrupting balance of cellular signals

Research showed that thyroid disease was present in 31 percent of the PH group, compared with only 15 percent in the control group. Also, at the time of initial PH evaluation, only about 55 percent of patients with hypothyroid...

Synchronous neuronal firing may underlie Parkinson's disease

Using electrodes finer than a human hair implanted into individual neurons, the researchers could monitor signals passed among neurons in the treate...

States that easily grant immunization exemptions have higher incidence of whooping cough
