Brain scans show unconscious woman played tennis in her head

Neuroscientists at Britain's Cambridge University say functional magnetic resonance imaging or fMRI brain scans appear to show that a woman in a vegetative state seemed to play tennis in her head despite the fact that she had been unconscious for five months after a motor vehicle accident.

Sex differences in general mental ability

A study published in the September 2006 issue of the journal Intelligence analyzed 145 items from the Scholastic Assessment Test (SAT) in 100,000 17- to 18-year-olds and found a male IQ advantage of 3.63 points.

Quantum dot nanodevice that can detect and image apoptosis

Aiming to help researchers get a better handle on how - and if - anticancer agents are triggering cell death, investigators at the University of Twente in The Netherlands have developed a quantum dot nanodevice that can detect and image apoptosis, also known as programmed cell death.

Scientists develop magnetic nanoparticles for medicine

Magnetic iron oxide nanoparticles have already proven their utility for imaging metastatic breast cancer lesions in sentinel lymph nodes, and numerous groups are attempting to use iron nanoparticles in other imaging applications.

New method for attaching tumor-targeting antibodies to the surface of buckyballs

Hollow buckyballs, spherical molecules made of sixty carbon atoms linked to one another like the panels of a soccer ball, have the potential to ferry large doses of anticancer drugs or imaging agents to tumors.

Researchers study cells whose membranes have been opened by ultrasound

Researchers have shown how ultrasound energy can briefly "open a door" in the protective outer membranes of living cells to allow entry of drugs and other therapeutic molecules – and how the cells themselves can then quickly close the door.

Endovascular repair of thoracic and abdominal aortic diseases as an alternative to open surgery in patients at high surgical risk

World Congress of Cardiology Report - Acute aortic syndromes, such as large thoracic and abdominal aortic aneurysms with impending rupture, complicated acute type B dissections, traumatic rupture of thoracic aorta, still represent life-threatening conditions.

Useful insights into mechanisms of catecholaminergic polymorphic ventricular tachycardia

World Congress of Cardiology Report - Familial genetic defects are responsible for several cases of unexpected sudden cardiac death in young and otherwise healthy individuals.

Anticipation plays a powerful role in human memory

Psychologists have long known that memories of disturbing emotional events - such as an act of violence or the unexpected death of a loved one - are more vivid and deeply imprinted in the brain than mundane recollections of everyday matters.

A wake-up call for parents of children with sleep apnea

In what is believed to be the first study showing neural changes in the brains of children with serious, untreated sleep apnea, Johns Hopkins researchers conclude that children with the disorder appear to suffer damage in two brain structures tied to learning ability.

Most effective treatments for people with coronary artery disease

Medication, angioplasty or surgery? For some heart disease patients, there's no clear-cut choice. The key to getting the best care is to follow your individual doctor's advice, new research shows.

Preoperative Functional MR Imaging localization of language and motor areas

By pinpointing the motor and language areas of the brain with functional magnetic resonance imaging (fMRI), surgeons can target brain tumors more effectively while reducing the risk of damaging important cognitive and motor processes.

Whole-brain T1 mapping in multiple sclerosis

The effects of multiple sclerosis (MS) extend beyond visibly affected areas into large portions of the brain that outwardly appear normal, according to a study appearing in the September issue of Radiology.

Inflammation in brain tissue a possible clue to autism

According to new research the common medical belief that young children with autism have accelerated brain growth is not the case even though their brains may appear enlarged.

New methods for screening nanoparticles and interaction with human cells

Scientists have developed a screening method to examine how newly made nanoparticles - particles with dimensions on the order of billionths of a meter - interact with human cells following exposure for various times and doses.

Dual-mode nanoscale imaging yields new details of cellular events

To create drugs capable of targeting malignancies, scientists must first decode exactly how a cell or a group of cells communicates with other cells and reacts to a broad spectrum of complex biomolecules surrounding it.

Autism affects the functioning of virtually the entire brain

A recent study provides evidence that autism affects the functioning of virtually the entire brain, and is not limited to the brain areas involved with social interactions, communication behaviors, and reasoning abilities, as had been previously thought.
