It's a dilemma many working parents: your child has a cough or a cold, do you send them to daycare?
Researchers from the University of Bristol have investigated the process of decision-making that parents go through when faced with this situation and find that parents viewed coughs and colds as less serious and not as contagious as sickness and diarrhea symptoms. This resulted in parents sending their child to daycare with a respiratory tract infection (RTI), which can result in the spread of similar illnesses in the wider community. 

Suicide remains the second leading cause of death for adolescents in the United States, this year nearly 5,000 adolescents will commit suicide and advocates claim over 500,000 will make an emergency room visit that is or could be a suicide attempt.
Better tools to evaluate, identify, and treat at-risk adolescents are crucial for the development and implementation of effective preventive strategies and a series of articles explores key factors that may contribute to suicidal risk and presents new assessment and treatment approaches.

The mosquito transmitted Chikungunya virus, which causes Chikungunya fever, is spreading continuously. No vaccine is so far available. Researchers of the Paul-Ehrlich-Institut have experimentally recombined segments of the virus surface protein E2, thus creating artificial proteins. The domain generated that way - "sAB+" - was able to confer a protective effect against Chikungunya virus to the animal. An immunization by means of this small protein fragment could thus provide a suitable approach to developing a Chikungunya vaccine.

Dropping off a child at kindergarten for the first time can be one of the most memorable yet terrifying experiences of parenthood. Among the many concerns parents face is the worry whether your child will make friends - a key factor, research shows, in reducing anxiety, depression and the likelihood of being bullied.
For parents of children with disabilities, the concern is even greater as four-out-of-10 of their children will enter kindergarten without the social skills necessary to develop close friendships. The response from schools has been to create inclusive classrooms, where a significant number of students with disabilities now receive the majority of their education and are believed to have a better chance at developing close relationships with peers.

Scientists have discovered that neurons use minor "DNA surgeries" to toggle their activity levels all day, every day, and since these activity levels are important in learning, memory and brain disorders, it could shed light on a range of important questions. 
"We used to think that once a cell reaches full maturation, its DNA is totally stable, including the molecular tags attached to it to control its genes and maintain the cell's identity," says Hongjun Song, Ph.D., a professor of neurology and neuroscience in the Johns Hopkins University School of Medicine's Institute for Cell Engineering. "This research shows that some cells actually alter their DNA all the time, just to perform everyday functions."

Bees play an invaluable role in maintaining biodiversity and in pollinating the crops that feed the world, so it is essential to improve our understanding of their biology and to investigate how they respond to environmental threats. Despite their often slow and apparently bumbling flights from flower to flower, bumblebees are anything but lazy. With over 250 bumblebee species globally, these important insects perform the laborious task of pollinating flowers in both wild and agricultural settings. A large number of fruits and vegetables would be missing from our plates had a bumblebee not done its job. 

Researchers gave bumblebees the option to choose between a sugar solution with nicotine in it and one without and found that bees infected with the Crithidia bombi parasite were more likely to go for the nicotine-laced nectar than those that weren't infected.

Happy Meals for broccoli?
A paper presented at the Pediatric Academic Societies (PAS) annual meeting in San Diego says that because poor food choices in school cafeterias are a risk factor for childhood obesity, students will make better choices if healthy foods are labeled with smiley faces and have prizes - similar to what fast food corporations do to try and make lunch more fun.

Centrioles - barrel-shaped structures inside cells- are made up of multiple proteins and since mutations in the proteins that make them up can cause a broad range of diseases, including developmental abnormalities, respiratory conditions, male sterility and cancer, they are the focus of a great deal of research

There may be more a natural way to reduce the use of pesticides but still save plants from attack -  by recreating a natural insect repellent based on smell.
Scientists from Cardiff University and Rothamsted Research have created tiny molecules which mirror a natural occurring smell known to repel insects by providing the enzyme ((S)-germacrene D synthase), which creates the smell, with alternative substrate molecules. 
The effectiveness of the smell or perfume to function as an insect repellent was tested and the team found that the smells repelled insects but in one case a reversal of behavior - an attractant - was observed which raises the prospect of being able to develop a trap-and-kill device. 

Celiac disease is a life-long condition that has severe consequences yet many people remain undiagnosed. 
Celiac disease is a genetically-determined, autoimmune condition caused by a permanent intolerance to gluten found in wheat, barley and rye. The condition causes inflammation in the small intestine, leading to diarrhea, weight loss, fatigue and other non-specific symptoms. It has been estimated that around 1% of the population may have Celiac disease, although estimates vary between countries. Its prevalence may be increasing. If left undiagnosed and untreated, CD can have a profound effect on quality of life may lead to adverse pregnancy outcomes and has been associated with a reduced life-expectancy.

Chemotherapy has been linked to excessive mind wandering and an inability to concentrate. The condition, colloquially called 'chemo-brain,' has long been suspected.
A new University of British Columbia study says it is the first to explain why patients have difficulty paying attention. Breast cancer survivors were asked to complete a set of tasks while researchers in the Departments of Psychology and Physical Therapy monitored their brain activity. What they found is that the minds of people with chemo-brain lack the ability for sustained focused thought.
