Light can be manipulated for creative and lucrative ends

The speed of light, 300 million metres per second, was long thought an immutable constant and has defined our understanding of matter and energy but recent research in the area of optics and photonics is proving that we can manipulate light to some ingenious and hugely lucrative ends.

Early schizophrenia symptoms include unusually high CA1 subfield activity

In the first functional magnetic resonance imaging (fMRI) study of its kind, neurologists and psychiatrists at Columbia University have identified an area of the brain involved in the earliest stages of schizophrenia and related psychotic disorders.

Future Alzheimer's treatments may be effective before the onset of symptoms

Memory lapses that occur with normal aging are a source of worry for many who fear Alzheimer's disease. Now a new Mayo Clinic-led study published in the July 16 issue of the New England Journal of Medicine suggests that the carriers of a common genetic risk factor for Alzheimer's disease begin to have memory declines in their mid-50s, far earlier than previously thought.

New findings on molecular imaging and prostate cancer

A new study published in the September issue of The Journal of Nuclear Medicine shows that positron emission tomography (PET)/computer tomography (CT) scans with the imaging agent choline could detect recurring prostate cancer sooner than conventional imaging technologies in some patients who have had their prostates surgically removed.

Research reveals that practicing Tetris increases brain efficiency

Researchers at the Mind Research Network today announced the findings of a scientific study that used brain imaging and Tetris to investigate whether practice makes the brain efficient because it increases gray matter. Over a three-month period, adolescent girls practiced Tetris, a computer game requiring a combination of cognitive skills. The girls who practiced showed greater brain efficiency, consistent with earlier studies. Compared to controls, the girls that practiced also had a thicker cortex, but not in the same brain areas where efficiency occurred.

Researchers discover elusive nanoscale movements of ribosomes at work

Researchers at the University of California, Berkeley, have for the first time captured elusive nanoscale movements of ribosomes at work, shedding light on how these cellular factories take in genetic instructions and amino acids to churn out proteins.

New noninvasive technique to detect colorectal and gastric cancers found

A preliminary evaluation of methylation of two gene promoters in fecal DNA showed promise as a noninvasive method to detect colorectal and gastric cancers, according to a new study published online August 21 in the Journal of the National Cancer Institute.

Molecules wrestle for supremacy to dictate the physical state of superstructures

Research at the University of Liverpool has found how mirror-image molecules gain control over each other and dictate the physical state of superstructures.

Sleep patterns can identify adolescents at greatest risk for depression

Sleep patterns can help predict which adolescents might be at greatest risk for developing depression, a researcher at UT Southwestern Medical Center has found in a five-year study.

Clever biochemical strategy enables bacteria to move freely and colonize host

A team of researchers from Boston University, Harvard Medical School and Massachusetts Institute of Technology recently made a discovery that changes a long held paradigm about how bacteria move through soft gels.

Noninvasive MRI helps diabetes diagnosis and treatment

Noninvasive imaging (MRI) may aid physicians in the early diagnosis, staging and treatment of diabetes, according to a study performed at Massachusetts General Hospital and Harvard Medical School in Boston, MA. This is the first study of its kind to apply noninvasive imaging techniques to diabetes research.

Cutting-edge imaging research aims to map brain injuries

In the first study of its kind, researchers at Saint Louis University are recruiting patients for a clinical trial that will use cutting-edge imaging equipment to map the brain injuries of combat veterans and civilians, aiming to better understand the nature of their injuries.

Scientists illuminate brain tumors with fluorescent nanoparticles

Brain cancer is among the deadliest of cancers. It's also one of the hardest to treat. Imaging results are often imprecise because brain cancers are extremely invasive. Surgeons must saw through the skull and safely remove as much of the tumor as they can. Then doctors use radiation or chemotherapy to destroy cancerous cells in the surrounding tissue.

New chemical imaging technique could help in the fight against atherosclerosis

A new chemical imaging technique could one day help in the fight against atherosclerosis, suggests research published in the August 2009 edition of the Journal of the Royal Society Interface.

Current diagnostic tests for ovarian cancer woefully ineffective

A new study finds that in order to make a significant dent in the mortality rate for the deadly cancer, the tests would have to be able to detect tumors of less than 1 cm in diameter, or about 200-times smaller in mass than those currently used to assess potential new tests. Still, if that hurdle can be overcome, there is good reason to believe that testing could make a big difference: The window of opportunity for treating these clinically undetectable cancers before they become life threatening is surprisingly long: about four years.

Compact gamma camera for prostate cancer imaging

The U.S. Department of Energy's Brookhaven National Laboratory and Hybridyne Imaging Technologies, Inc., of Toronto, Canada, have won a 2009 R&D 100 Award for developing a compact gamma camera for high-resolution imaging of prostate cancer.

Migrant neuron: New imaging studies reveal mechanics of neuron migration

The development of the brain proceeds a little like the European settlement of North America. The earliest pioneers settled on the east coast with subsequent waves of settlers forming communities further and further westward. In cortical regions of the developing brain, generations of young neurons undergo a staged migration as well, with the earliest-born cells staying relatively close to their birthplace and subsequent generations traveling further, ultimately stratifying into six neuronal layers in the mature brain. Now, for the first time, imaging studies have identified the "motors" that propel a unique form of cell migration that creates these layers that

New treatments for infertility could be in the pipeline

Scientists at the University of Otago have found in their research into the brain circuits which control human fertility, that instead of the usual synapses, fertility is controlled by a thousand or so special neurons, which are linked by long, branch-like dendrites and they believe their discovery could lead to the development of new treatments for infertility.
