Could poor sleep contribute to symptoms of schizophrenia? Posted: 14 Nov 2012 10:45 AM PST Neuroscientists studying the link between poor sleep and schizophrenia have found that irregular sleep patterns and desynchronized brain activity during sleep could trigger some of the disease's symptoms. The findings suggest that these prolonged disturbances might be a cause and not just a consequence of the disorder's debilitating effects.

Tolerance to malaria by means of iron control Posted: 14 Nov 2012 10:40 AM PST Malaria is a life-threatening condition that exposes approximately half of the world's population to the risk of developing a severe and often lethal form of disease. Researchers have discovered that the development of severe forms of malaria can be prevented by a simple mechanism that controls the accumulation of iron in tissues of the infected host.

Rare parasitic fungi could have anti-flammatory benefits Posted: 14 Nov 2012 10:40 AM PST Caterpillar fungi are rare parasites found on hibernating caterpillars in the mountains of Tibet. For centuries they have been highly prized as a traditional Chinese medicine - just a small amount can fetch hundreds of dollars.

20-year-old stroke patient part of growing trend of strokes in young people Posted: 14 Nov 2012 10:39 AM PST Michelle Nimmerrichter was only 20 when she suffered a stroke that left her in a coma and on a ventilator. She appears to be part of a trend -- a recent study found that strokes are affecting people at younger ages.

Exposure to light at night may cause depression, learning issues, mouse study suggests Posted: 14 Nov 2012 10:39 AM PST For most of history, humans rose with the sun and slept when it set. Enter Thomas Edison and colleagues, and with a flick of a switch, night became day, enabling us to work, play and post cat and kid photos on Facebook into the wee hours. According to a new study of mice, however, this typical 21st-century scenario may come at a serious cost: When people routinely burn the midnight oil, they risk suffering depression and learning issues, and not only because of lack of sleep. The culprit could also be exposure to bright light at night from lamps, computers and even iPads.

Cancer therapy: Nanokey opens tumors to attack Posted: 14 Nov 2012 08:38 AM PST There are plenty of effective anticancer agents around. The problem is that, very often, they cannot gain access to all the cells in solid tumors. A new gene delivery vehicle may provide a way of making tracks to the heart of the target.

New brain gene gives us edge over apes, study suggests Posted: 14 Nov 2012 08:34 AM PST Scientists have taken a step forward in helping to solve one of life's greatest mysteries -- what makes us human?

Pancreas stem cell discovery may lead to new diabetes treatments Posted: 14 Nov 2012 08:34 AM PST Stem cells in the adult pancreas have been identified that can be turned into insulin producing cells, a finding that means people with type 1 diabetes might one day be able to regenerate their own insulin-producing cells.

Brain waves make waves Posted: 14 Nov 2012 08:33 AM PST Naturally, our brain activity waxes and wanes. When listening, this oscillation synchronizes to the sounds we are hearing. Researchers have found that this influences the way we listen. Hearing abilities also oscillate and depend on the exact timing of one's brain rhythms. This discovery that sound, brain, and behavior are so intimately coupled will help us to learn more about listening abilities in hearing loss.

Engineering a photo-switch for nerve cells in the eye and brain Posted: 14 Nov 2012 08:29 AM PST Chemists and vision scientists have designed a light-sensitive molecule that can stimulate a neural response in cells of the retina and brain -- a possible first step to overcoming degenerative eye diseases like age-related macular degeneration, or to quieting epileptic seizures.

PCBs, other pollutants may play role in pregnancy delay Posted: 14 Nov 2012 05:40 AM PST Couples with high levels of PCBs and similar environmental pollutants take longer to achieve pregnancy in comparison to other couples with lower levels of the pollutants, according to a preliminary study.

Not what you consciously thought: How we can do math problems and read phrases nonconsciously Posted: 14 Nov 2012 05:39 AM PST Can we actually read words and phrases and solve multi-step mathematical problems without our having consciously been aware of them? A team of psychologists has conducted a series of experiments that give a positive answer: people can read and do math nonconsciously.

A risk gene for cannabis psychosis Posted: 14 Nov 2012 05:39 AM PST The ability of cannabis to produce psychosis has long been an important public health concern. This concern is growing in importance as there is emerging data that cannabis exposure during adolescence may increase the risk of developing schizophrenia, a serious psychotic disorder. Further, with the advent of medical marijuana, a new group of people with uncertain psychosis risk may be exposed to cannabis.

Smoking affects allergy-relevant stem cells Posted: 14 Nov 2012 05:39 AM PST Environmental contaminants, such as smoking, are harmful to the human organism in relation to the occurrence of allergies. Until now, researchers had never investigated whether and to what extent environmental contaminants also affect allergy-relevant stem cells. For the first time, researchers have found evidence that smoking affects the development of peripheral allergy-relevant stem cells in the blood.

Triclosan in cosmetics and personal care products can increase allergy risk Posted: 14 Nov 2012 05:38 AM PST Triclosan - an antibacterial chemical found in toothpaste and other products - can contribute to an increased risk of allergy development in children.

BPA shown to disrupt thyroid function in pregnant animals and offspring Posted: 14 Nov 2012 05:32 AM PST In utero exposure to bisphenol A (BPA) can be associated with decreased thyroid function in newborn sheep, according to a recent study.

Timing of first menstual cycle may be predictor of cardiovascular disease risk in women Posted: 14 Nov 2012 05:32 AM PST Age at onset of menarche (first menstrual cycle) is associated with increased body mass index (BMI), waist circumference, and overall obesity in adulthood, according to a recent study.

Cancer: Exercise reduces tiredness Posted: 13 Nov 2012 06:49 PM PST Aerobic exercise can help relieve the fatigue often associated with cancer and cancer treatment, according to researchers. Their updated systematic review strengthens findings from an earlier version on cancer-related fatigue.

How threat, reward and stress come together to predict problem drinking Posted: 13 Nov 2012 06:46 PM PST Having a drink after a stressful day at work may seem like a natural response for some, but can your neural circuits predict when a drink or two will become problem drinking? A new study suggests that may be the case. The study describes a highly novel mechanism predicting problem drinking in college students from fMRI data measuring individual differences in the functioning of reward and threat circuits in the brain.

Metals versus microbes: The biocidal effect of metalloacid-coated surfaces Posted: 13 Nov 2012 06:46 PM PST A new study reports of a phenomenon that could help control the spread of hospital-acquired infections: a surface-coating of metalloacids kills off microbial strains, even in multidrug-resistant microorganisms.

Relatives of people who die suddenly from heart problems have greatly increased risk of cardiovascular disease Posted: 13 Nov 2012 06:46 PM PST Relatives of young people who have died suddenly from a heart-related problem are at greatly increased risk of developing cardiovascular disease, according to a new study.

Bacterial DNA sequence used to map an infection outbreak Posted: 13 Nov 2012 06:46 PM PST For the first time, researchers have used DNA sequencing to help bring an infectious disease outbreak in a hospital to a close. Researchers used advanced DNA sequencing technologies to confirm the presence of an ongoing outbreak of methicillin-resistant Staphylococcus aureus (MRSA) in a Special Care Baby Unit in real time. This assisted in stopping the outbreak earlier, saving possible harm to patients. This approach is much more accurate than current methods used to detect hospital outbreaks.
