Cost-effective expert recommended asthma test underutilized by physicians, study shows

Mon, 04/05/2015 - 4:10pm
For the first time, researchers have found that spirometry was underutilized for asthma diagnosis and management in US adults from 2001 to 2011, despite its accuracy, cost effectiveness and the publication of national guidelines advocating its use. Spirometry is a common test that allows physicians to determine how well a person's lungs work by measuring how much air is inhaled and exhaled as well as how quickly the air is exhaled.

Study points to possible treatment for lethal pediatric brain cancer

Mon, 04/05/2015 - 4:10pm
Using brain tumor samples collected from children in the United States and Europe, an international team of scientists found that the drug panobinostat and similar gene regulating drugs may be effective at treating diffuse intrinsic pontine gliomas, an aggressive and lethal form of pediatric cancer.

Defects in atomically thin semiconductor emit single photons

Mon, 04/05/2015 - 4:10pm
Researchers have shown that defects on an atomically thin semiconductor can produce light-emitting quantum dots. The quantum dots serve as a source of single photons and could be useful for the integration of quantum photonics with solid-state electronics -- a combination known as integrated photonics.

Mystery of India’s rapid move toward Eurasia 80 million years ago explained

Mon, 04/05/2015 - 4:08pm
In the history of continental drift, India has been a mysterious record-holder. More than 140 million years ago, India was part of an immense supercontinent called Gondwana, which covered much of the Southern Hemisphere. Around 120 million years ago, what is now India broke off and started slowly migrating north, at about 5 centimeters per year.

School competitive food policies appears tied to neighborhood socioeconomics

Mon, 04/05/2015 - 4:08pm
Policy changes in California to make the food and beverages that compete with school meal programs more healthy for students appear to have improved childhood overweight/obesity prevalence trends, although improvement was better among students attending schools in socioeconomically advantaged neighborhoods.

Scientists reconcile three unrelated theories of schizophrenia

Mon, 04/05/2015 - 4:08pm
A new study in mice links three previously unrelated hypotheses about the causes of schizophrenia, a debilitating mental disorder that affects how people think, act and perceive reality. The new findings may eventually lead to treatment strategies targeted for the underlying causes of schizophrenia and related disorders.

Foundations of heart regeneration uncovered: Outer layer of heart must be healed first

Mon, 04/05/2015 - 4:08pm
Medical researchers have found that a key to the zebrafish's ability to regenerate cardiac tissue lies in the outer layer of the heart known as the epicardium. When this critical layer is damaged, the whole repair process is delayed as the epicardium undergoes a round of self-healing before tending to the rest of the heart. The finding points to a possible target for repairing the damage caused by a heart attack.

Juvenile shale gas in Sweden

Mon, 04/05/2015 - 4:05pm
Considering geological time scales, the occurrence of biogenic shale gas in Sweden´s crust is relatively young. Geoscientists found that biogenic methane in the Alum Shale in South Sweden formed due to deglaciation around 12 years ago. Moreover, the formation processes were due to complex interactions between neotectonic activity and the occurrence of a deep biosphere. Applying a new hydrogeochemical modelling approach, the specific methane generation process was unraveled and quantified for the first time in Europe.

Researchers hope to improve dental health by changing caregiver's behavior

Mon, 04/05/2015 - 3:30pm
Studies have long associated low-income areas with poor oral health. But dental researchers have sensed that other factors related to income may be at work -- in particular, education level. So they recently investigated how a parent or other caregiver's education level and dental habits affect children's dental health.

Personal cues can have a strong effect on craving in individuals with addiction

Mon, 04/05/2015 - 3:29pm
Unique person-specific cues -- such as the presence of a specific friend or hearing a specific song -- appear to have a robust effect on craving addictive substances, a recent study shows. The study also found that person-specific cues may have a longer effect on craving than more general substance-specific cues, such as the presence of bottles, syringes, or lighters.
