fMRI captures wave of brain activity linked to anticipation

Neuroscientists at Georgetown University Medical Center have, for the first time, shown what brain activity looks like when someone anticipates an action or sensory input which soon follows.

Amyloid plaques may increase the activity of astrocytes

The impact of the amyloid plaques that appear in the brains of patients with Alzheimer's disease may extend beyond the deposits' effects on neurons – the cells that transmit electrochemical signals throughout the nervous system.

Scientists measure impact of high-fat diet on the spread of cancer

Researchers at Purdue University have precisely measured the impact of a high-fat diet on the spread of cancer, finding that excessive dietary fat caused a 300 percent increase in metastasizing tumor cells in laboratory animals.

Ethnic differences found for fatty liver disease and insulin resistance

A new study suggests that the metabolic response to obesity and insulin resistance, particularly as it pertains to the liver, differs among ethnic groups in the U.S. African-Americans are more resistant to the buildup of fat in the abdominal adipose tissue and liver, and to high triglyceride levels associated with insulin resistance.

Doors open soon at new $360 million hospital with all-private rooms

When the doors to the new Henry Ford West Bloomfield Hospital open March 15, patients, their families and the community will find a health care experience unlike any other, offering the latest in medicine, technology and patient safety, integrated with wellness and prevention programs all under one roof.

Brain mechanism recruited to reduce noise during challenging tasks

New research reveals a sophisticated brain mechanism that is critical for filtering out irrelevant signals during demanding cognitive tasks.

New insights into addiction

A new comprehensive review by researchers at the Montreal Neurological Institute (MNI), McGill University and the University of Cambridge, England provides vital insights into the neurological basis of addiction by investigating Parkinson's disease patients, who in some instances develop various addictions when undergoing medical treatment.

Scientists identify stem-cell genes that help form plant organs

Plant stem-cells are master cells located at the tip of the stem and are part of a structure called the shoot apical meristem (SAM).

Physical fitness improves spatial memory, increases size of hippocampi

When it comes to the hippocampus, a brain structure vital to certain types of memory, size matters.

Targeted nanospheres find, penetrate, then fuel burning of melanoma

Hollow gold nanospheres equipped with a targeting peptide find melanoma cells, penetrate them deeply, and then cook the tumor when bathed with near-infrared light. When heated with lasers, the actively targeted hollow gold nanospheres did eight times more damage to melanoma tumors in mice than did the same nanospheres that gathered less directly in the tumors.

Radiolabeled nanoparticles boost PET-CT combination imaging

In an attempt to decrease the amount of cancer-targeting nanoparticle needed to image tumors, a team of investigators at the Massachusetts General Hospital and Harvard Medical School has developed a simple method for creating iron oxide nanoparticles labeled with 18F, a radioisotope that is easily detected using positron emission tomography (PET). The result is a nanoparticle that can be imaged using PET, computerized tomography (CT), and fluorescence imaging.

Nanoparticles detect dying cancer cells

Two years ago, researchers at the University of South Australia discovered a new molecular marker specific for chemotherapy-induced cancer cell death. Now, those same investigators have used this marker to develop an imaging agent that can pinpoint tumor cell death using magnetic resonance imaging.

Microfluidic device mimics tumor microenvironment, helps drug discovery

One of the challenges that cancer researchers face in designing new antitumor agents is that of predicting how drug molecules will behave in the complex microenvironment that surrounds a tumor. In particular, tumors create all sorts of chemical and physical barriers that limit how much drug is able to enter a tumor, let alone reach cells deep within a tumor.

New imaging techniques let scientists see biomolecules more clearly

Scientists have always wanted to take a closer look at biological systems and materials. From the magnifying glass to the electron microscope, they have developed increasingly sophisticated imaging devices.

FDA approves humanitarian device exemption for deep brain stimulator

The U.S. Food and Drug Administration has approved a humanitarian device exemption for the first implantable device that delivers intermittent electrical therapy deep within the brain to suppress the symptoms associated with severe obsessive-compulsive disorder (OCD).

Echoes discovered in early visual brain areas play role in working memory

Vanderbilt University researchers have discovered that early visual areas, long believed to play no role in higher cognitive functions such as memory, retain information previously hidden from brain studies.
