Researchers at the Research Institute of the McGill University Health Centre (MUHC) and the Lady Davis Institute for Medical Research of the Sir Mortimer B.

Gene enhances prefrontal function at a price
Studies of a gene that affects how efficiently the brain's frontal lobes process information are revealing some untidy consequences of a tiny variation in its molecular structure and how it may increase susceptibility to schizophrenia.

Nominations now being accepted for a major award in cancer prevention research
The American Association for Cancer Research (AACR) and the Cancer Research and Prevention Foundation (CRPF) announce that nominations are now being accepted for a major international Award in recognition of outstanding cancer prevention research.

UI researchers discover new cause of muscular dystrophies
In muscle building, exercise causes tears in muscle membrane and the healing process produces an increased amount of healthy muscle.

Evidence for potassium as misisng heat source in planetary cores
There's a small problem with Earth's magnetic field: It should not have existed, as Earth's rock record indicates it has, for the past 3.5 billion years.

New study in rats matches genetic influences and cognitive impairment
A study in rats matching the activity of 146 genes with brain aging and impaired learning and memory produces a new picture of brain aging and cognitive impairment.

MR accurate in detecting residual disease following lumpectomy
Some breast cancer patients who undergo a lumpectomy should then be considered for an MR examination because MR is an accurate way to look for any disease left in the breast, two new studies show.

Alternative method for colon cancer screening is more comfortable for patients
CT colonography (CTC), combined with a low residue and hydration-controlled diet, but without cathartic cleansing, is showing promise as a potential tool to detect colon cancer early, preliminary results of a study show.

Barium studies should be first step in diagnosing complications from reflux disease surgery
Barium studies should be the first line of defense in diagnosing problems that can occur following surgery for reflux disease, a new study shows.

Diffusion-weighted MR imaging accurately detects stroke
Diffusion-weighted MR imaging is an accurate way to detect whether a patient has had a stroke--even 24 hours after the patient's initial symptoms began, a new study shows.

Colonoscopy far more cost-effective against colon cancer than promising Cox II drugs, study predicts
A new study gives Americans over 50 one more reason not to put off having a colonoscopy to check for colon cancer and its forerunners.

Newly discovered mutations possibly linked to breast cancer
In a study published this week in the New England Journal of Medicine, a researcher at the University of Illinois at Chicago has identified two previously unknown mutations that cause excessive estrogen production in men -- and may be linked to certain kinds of breast cancer.

Lessons from lives of 37 Texas murderers show different paths to death row
Murder often begins at a terrifyingly young age. It is an awful journey -- frequently launched by physical and sexual violence, bullying and neglect-- that terminated in 1997 with the execution of 37 men convicted of murder in Texas.

MR technique shows brains of Alzheimer's patients similar to immature brains in children
A new MR imaging technique used to study white matter in the brain has found something intriguing--the brains of Alzheimer's patients show some of the same signs as the immature brains of children.

Genetic regulator of lifespan identified
Researchers at Harvard Medical School have discovered that a gene in yeast is a key regulator of lifespan.

Engineered proteins will lead to 'synthetic biology'
Duke University Medical Center biochemists have developed a computational method to design proteins that can specifically detect a wide array of chemicals from TNT to brain chemicals involved in neurological disorders.

Interventional procedures effectively treat complications from bypass surgery
Obese patients who have complications following gastric bypass surgery may avoid a second, oftentimes risky, surgery if interventional radiology procedures can be performed to treat these complications, a new study shows.

ALife experiments show how complex functions can evolve
If the evolution of complex organisms were a road trip, then the simple country drives are what get you there.

Study supports the use of general radiologists during off hours
A general radiologist can be a good, first line of defense in the evaluation of emergency CT scans during off hours, when neuroradiologists are unavailable, a recent study shows.

Artificial life experiments show how complex functions can evolve
If the evolution of complex organisms were a road trip, then the simple country drives are what get you there.

Marc Deshusses, associate professor in the department of chemical and environmental engineering, and his postdoctoral researcher, David Gabriel, report in the Proceedings of the National Academy of Sciences that they have modified an existing full-scale chemical scrubber at the Orange County Sanitation District, California, to a biological trickling filter.

Whole body MR imaging could replace bone scans in cancer patients
Whole body MR is superior to bone scans in determining how far cancer has spread into the bone marrow and bones, a new study shows.
