Evaluate Linear And Angular Insertion Depth Measurements Of Cochlear Implants

According to a study, researchers examine the linear and angular insertion depth measurements of cochlear implants based on conventional computed tomography. Imaging exams play a key role in cochlear implants about both planning implantation before surgery and quality control after surgery. The ability to visualize the three-dimensional location of implanted electrodes is useful in clinical routines for assessing patient outcome.

New Protein Could Point To New Targets For Treatment

Researchers could develop new cancer drugs that specifically target Gαs. A new view of a protein frequently mutated in pituitary tumors is overturning conventional wisdom and could point to novel targets for cancer drugs.  The protein, a "G protein" called Gαs, initiates messages inside cells. But a single mutation surprisingly alters Gαs action. The protein's molecular "off switch" actually switches activity on. The study was published in the journal Cell.

Ferrets Could Reveal The Size Of Human brain

A genetically engineered ferret could help reveal how humans got their big brains. By inactivating a gene linked to abnormally small brain size in humans, researchers have created the first ferret with a neurological mutation. Although the original impetus of the work was to study human brain disease and development, says Howard Hughes Medical Institute (HHMI) Investigator Christopher Walsh, the results also shed light on how the human brain expanded during evolution. The study was published in the journal Nature.

Russian researchers develop new biosensor chips based on unconventional materials

Russian researchers from the Moscow Institute of Physics and Technology have developed biosensor chips of unprecedented sensitivity, which are based on copper instead of the conventionally used gold. Besides making the device somewhat cheaper, this innovation will facilitate the manufacturing process.

The research findings are reported in the journal Langmuir, named in honor of Irving Langmuir — a U.S. scientist awarded the 1932 Nobel Prize in chemistry "for his discoveries and investigations in surface chemistry."
