Medical isotope producers and the CTBTO join forces to reduce radioxenon emissions
The nuclear test monitoring agency, CTBTO, joins forces with a Belgium producer of radioelements for nuclear medicine to reduce radioactive noble gas emissions. By reducing the amount of radioactive xenon released in the production of isotopes for nuclear medicine, it will help the world's nuclear test-ban monitors to focus on detecting atomic explosions.

ESA's billion-star surveyor, Gaia, has completed final preparations in Europe and is ready to depart for its launch site in French Guiana, set to embark on a five-year mission to map the stars with unprecedented precision.
Projections of climate change impacts on wheat production uncertain: A call for model improvement
Crop models estimating wheat yields disagree considerably under climate change scenarios. The largest worldwide crop model ensemble study proves that uncertainties in simulated impacts increase with carbon dioxide concentrations and associated warming. It was found that an ensemble model approach currently has advantages over individual crop models when it comes to projections of multiple agroecosystem variables under climate change.
Characterizing forest properties and microclimate using numerical modelling and remote sensing
(Phys.org) —Researchers from Universiti Teknologi MARA conducted a highly innovative study which focuses on understanding the spatio-temporal dynamics of the microclimatic conditions in canopy gaps in forests. Furthermore, the combination of numerical modelling techniques and remote sensing is unique in this context. In this way, the project is extremely well placed to make substantive contributions to both ecological modelling and remote sensing science.
Some Americans are cooling off on global warming
A complaint-worthy winter has led to a drop in the number of Americans who believe that global warming is real, according to a University of Michigan survey.
Robotic probe launcher may transform ocean data collection
Our understanding of the ocean and its variability relies on the tools ocean scientists deploy to collect data. One tool routinely used is the eXpendable BathyThermograph (XBT) probe, which is usually deployed by hand one at a time at sea.
Cattle grazing, clean water compatible on public lands
Cattle grazing and clean water can coexist on national forest lands, according to research by the University of California, Davis.

Far more of Earth's water was locked up as ice at the height of the last ice age than previously thought, and current climate change models may need to be adjusted to account for it, according to a new study.
Survivor of stellar collision is new type of pulsating star
A team of astronomers from the UK, Germany and Spain have observed the remnant of a stellar collision and discovered that its brightness varies in a way not seen before on this rare type of star. By analysing the patterns in these brightness variations, astronomers will learn what really happens when stars collide. This discovery will be published in the 27 June 2013 issue of the journal Nature.
Climate change threatens forest survival on drier, low-elevation sites
Predicted increases in temperature and drought in the coming century may make it more difficult for conifers such as ponderosa pine to regenerate after major forest fires on dry, low-elevation sites, in some cases leading to conversion of forests to grass or shrub lands, a report suggests.
Major changes needed for coral reef survival
To prevent coral reefs around the world from dying off, deep cuts in carbon dioxide emissions are required, says a new study from Carnegie's Katharine Ricke and Ken Caldeira. They find that all existing coral reefs will be engulfed in inhospitable ocean chemistry conditions by the end of the century if civilization continues along its current emissions trajectory. Their work will be published July 3 by Environmental Research Letters.
Drilling study finds faults after earthquakes heal faster than previously thought
(Phys.org) —A team of Chinese researchers along with representatives from the US and Japan have found that ground fractures along fault lines due to earthquakes appear to heal faster than previously thought. In their paper published in the journal Science, the team reports on data found by boring holes along the fault line responsible for the 2008 Sichuan earthquake in China.

Medicine & Health news

Registered dietitians help critically ill children get necessary nutrition for recovery

Dynamic disorders of the upper respiratory tract in warm-blooded and cold-blooded trotter racehorses
(Medical Xpress)—Eric Strand's doctoral research shows that these genetically distinct breeds are predisposed to different types of upper airway problems, and this indicates that certain physical traits can be the cause of different forms of collapse in the upper respiratory tract. Strand has also developed and standardised a new diagnostic treadmill protocol for disorders of this kind, which has resulted in more accurate diagnosis and the discovery of new disorders.

Study reveals potential of genetic testing to predict which children will grow out of asthma
New research published in The Lancet Respiratory Medicine, suggests that genetic risk assessments could be used to predict which children with asthma are likely to grow out of the condition and which will continue having symptoms as they grow older.
Higher genetic risk tied to lifetime asthma suffering
Children with more genetic risks for asthma are not only more likely to develop the condition at a young age, but they are also more likely to continue to suffer with asthma into adulthood. The finding reported by Duke University researchers is one of the latest to come from a 40-year longitudinal study of New Zealanders.
Time is of the essence for reducing the long-term effects of iron deficiency

The results show that each 0.1 g per day or 0.1% energy per day increment of intake of n-3 polyunsaturated fatty acid (n-3 PUFA) derived from fish was associated with a 5% reduction in risk. To achieve this risk reduction, intake of oily fish such as salmon, tuna or sardines should be 1-2 portions per person per week.

Brain imaging shows how prolonged treatment of a behavioral disorder restores a normal response to rewards
Attention-deficit/hyperactivity disorder (ADHD) is characterized by abnormal behavioral traits such as inattention, impulsivity and hyperactivity. It is also associated with impaired processing of reward in the brain, meaning that patients need much greater rewards to become motivated. One of the common treatments for ADHD, methylphenidate (MPH), is known to improve reward processing in the short term, but the long-term effects have remained unclear.

Up to 15 percent of patients who take cholesterol-lowering statin medications experience muscle pain or other side effects, and many patients simply stop taking the drugs.
Type 2 diabetes patients transplanted with own bone marrow stem cells reduces insulin use
A study carried out in India examining the safety and efficacy of self-donated (autologous), transplanted bone marrow stem cells in patients with type 2 diabetes (TD2M), has found that patients receiving the transplants, when compared to a control group of TD2M patients who did not receive transplantation, required less insulin post-transplantation.

A new study from the Perelman School of Medicine at the University of Pennsylvania and the Naval Health Research Center has shown military service members who have trouble sleeping prior to deployments may be at greater risk of developing posttraumatic stress disorder (PTSD), depression and anxiety once they return home. The new study, published in the July 2013 edition of the journal SLEEP, found that pre-existing insomnia symptoms conferred almost as a large of a risk for those mental disorders as combat exposure.
