New insights into brain cell metabolism from PET and MRI scans

By discovering a crucial piece of submicroscopic information about how the brain converts fuel into energy for neurons, Cornell University biophysicists have gleaned new insights into brain cell metabolism that will allow neurologists to better interpret data from such diagnostic tests as positron emission tomography (PET) scans and a specialized magnetic resonance imaging (MRI) test.

Children who snore are far more likely to suffer hyperactivity disorders

Several years ago, University of Michigan researchers published some of the strongest evidence yet that children who snore when they sleep are far more likely to have attention and hyperactivity problems than their non-snoring peers.

Short-term use of CPAP therapy may protect against cardiovascular disease

A common sleep therapy used to treat patients with obstructive sleep apnea (OSA) may actually have a protective effect against death related to cardiovascular disease.

Scientists confirm rarefied air poses in-flight problem

More than half of all air passengers experience significant blood oxygen decreases at high altitudes, UK researchers report in the scientific journal Anaesthesia. We take a look at the findings and EU research in the aeronautics field.

Hospitalized babies with severe breathing problems may benefit from lying on their stomachs

Infants who are hospitalized with severe breathing problems may benefit from being placed on their stomachs rather than their backs, according to a new review of recent studies.

Images of brain activity may hold clues to the onset of schizophrenia

Images of brain activity may hold clues to the onset of schizophrenia in people at high risk for the disease, according to a study headed by psychiatry researchers at the University of North Carolina at Chapel Hill School of Medicine.

Mountaineering doctors hike medicine to new heights with Xtreme Everest

Doctors working at the edge of extreme are set to climb the world’s tallest mountain to look death in the face – and take its pulse. The medical research team will make the first ever measurements of blood oxygen in the ‘death zone’, at altitudes above 8,000 metres where the human body has struggled - and frequently failed - to survive.

New understanding of the causes for symptoms of sickle cell disease

A new understanding of the causes for symptoms of sickle cell disease, a condition affecting one in every 600 African-Americans, has resulted from a study by researchers at Duke University Medical Center and Howard Hughes Medical Institute (HHMI). Their findings may lead to a new, more direct method for treating the disease, they said.

Anesthetics are effective in reducing the pain of circumcision in newborns

Anesthetics are effective in reducing the pain of circumcision in newborns, judging from the baby’s heart rate and time spent crying after the procedure, a new analysis finds.

Children who have problems breathing during sleep tend to score lower on tests of mental development and intelligence

Children who have problems breathing during sleep tend to score lower on tests of mental development and intelligence than do other children their age, according to two studies funded by the National Institutes of Health (NIH). Both studies appear in the October issue of Journal of Pediatrics.

Researchers to conduct a series of studies on human circulation

Penn State College of Medicine researchers recently were awarded a five-year, $7 million grant from the National Heart, Lung and Blood Institute of the National Institutes of Health to conduct a series of studies on human circulation.

MRI may be better than polygraph for revealing lies

A new study involving people telling lies while undergoing functional magnetic resonance imaging (fMRI) provides early indications that understanding the brain basis of deception may lead to a better lie detection method than polygraph tests.

We know they need caffeine, but how it works on the newborn is the subject of a new study

Every morning, millions of adults consume voluminous cups of coffee, seeking the jolting effect of caffeine. As these adults consume their coffee, they do so unaware that some of the youngest Americans are also getting a treatment of caffeine - not to stay awake, but to assist in treating a major sleep disorder found in some neonates.

Positron emission tomography offers a better way to observe the damage that strokes and neurodegenerative diseases wreak on brain cells

A laser-based microscopy technique may have settled a long-standing debate among neuroscientists about how brain cells process energy

Potential new strategy for blocking tumor growth

Targeting a master molecule that helps cancer cells survive when blood oxygen levels are low may offer a potentially powerful strategy for blocking tumor growth, say researchers at The University of Texas M. D. Anderson Cancer Center.

NASA develops "Black Box" to monitor vital signs

When planes have a problem, analysts can usually figure out what went wrong. They simply check the plane's "black box," which records exactly what was happening to the plane at the time. Now, there's something similar for people. Under the leadership of NASA/Ames design engineer Carsten Mundt, researchers have developed a device that, Stanford electrical engineer and team member Greg Kovacs says, is a black box for human beings.
