In a cluster of articles released today in the peer reviewed European Journal of Psychotraumatology, researchers provide new insights into the treatment of children and youth exposed to acts of terror. The work is drawn from studies examining the mass shooting at Utoya, Norway in 2011, and two school shootings in Finland – Jokela in 2007 and Kauhajoki in 2008.

Angiogenesis, the sprouting of new blood vessels from pre-existing ones, is essential to the body's development.

Besides obscuring the stars, light pollution can also disrupt the reproduction of light-sensitive animals. French scientists have shown that light pollution can override the natural reproductive cycle of some animals, making them sexually active out of season.

Austrian researchers have found that jetlag has severe effects on red blood cells, possibly explaining the high incidence of heart disease seen in shift workers. However, these effects can be counterbalanced by fresh, young red blood cells – making blood donations a potential therapy for shift workers.

Israeli scientists have discovered that scorpion burrows have a platform on which to warm up before the evening hunt.

Long jumpers and triple jumpers spend hours training to perfect their take-off. But what influences their performance? Scientists have discovered that taking off from a compliant surface (such as a springboard) compared with a firm, unyielding surface, reduces the energy cost of jumping over long distances.

A systematic review and meta-analysis of available data published in Diabetologia (the journal of the European Association for the Study of Diabetes) suggests that combined aerobic and resistance training, rather than either alone, is best for controlling both blood sugar and blood fat profiles among people with type 2 diabetes. However the authors stress that the strength of the results is weakened when studies with high risk of bias are removed, and thus more high quality trials are needed to make more definitive conclusions.

Health security in 2014: building on preparedness knowledge for emerging health threats

Pediatric patients with intestinal failure often need gastrostomy tubes, or feeding tubes inserted into an opening created in the stomach, for long-term nutrition. The use of such tubes can lead to persistent gastrocutaneous fistulae, or the failure of the opening to close on its own, resulting in a need for surgical closure.

More than one quarter of children with two copies of a high-risk variant in a specific group of genes develop an early sign of celiac disease called celiac disease autoimmunity (CDA) by age 5. The findings are from The Environmental Determinants of Diabetes in Youth consortium, or TEDDY . The National Institutes of Health-funded study, published July 2 in the New England Journal of Medicine, also found that participants in Sweden had higher rates of celiac disease than participants in the United States, Finland and Germany, even with the same genetic risks.

MINNEAPOLIS – People with mild to moderate Parkinson's disease who regularly walk for exercise may improve their motor function, mood, tiredness, fitness and some aspects of thinking abilities, according to a study published in the July 2, 2014, online issue of Neurology®, the medical journal of the American Academy of Neurology.
