A good example of the connection between cause and effect, is that an object which contains food produces noise when shaken. The study of an international research team at the Wolf Science Center of the Vetmeduni Vienna shows how animals deal with these rules of the physical world. Based on where dogs and wolves searched for food after receiving some hints about its location, they showed that our domesticated, four-legged companions cannot make the connection between cause and effect, but wolves can. These results indicate that domestication has changed the dogs' cognitive abilities.

CHICAGO - Researchers examining pediatric firearm injuries found that the age a child is injured by a gun is closely related to where he or she lives: the city or the country.

The study abstract, "Hospitalizations for Firearm Injuries in Children and Adolescents in the US: Rural Versus Urban," will be presented Monday, Sept. 18, at the American Academy of Pediatrics National Conference & Exhibition in Chicago.

RIVERSIDE, Calif. - Researchers at the University of California, Riverside have found that thirdhand-smoke (THS) exposure has a significant effect on health as early as one month after initiation of exposure -- an effect that worsens with time.

THS results when exhaled smoke and smoke emanating from the tip of burning cigarettes gets on surfaces such as clothing, hair, homes, and cars. THS has been shown, in mice, to cause type 2 diabetes, hyperactivity, liver and lung damage, and wound-healing complications.

RICHLAND, Wash. - Many seashells, minerals, and semiconductor nanomaterials are made up of smaller crystals, which are assembled together like the pieces of a puzzle. Now, researchers have measured the forces that cause the crystals to assemble, revealing an orchestra of competing factors that researchers might be able to control.

RIVERSIDE, Calif. - Unsuccessful courtship attempts by males create aversive memories that can reduce their level of enthusiasm for subsequent courtship attempts. Scientists at the University of California, Riverside and colleagues have attempted to understand this behavior at the molecular level.

CAMBRIDGE, Mass. -- MIT engineers have invented a new 3-D fabrication method that can generate a novel type of drug-carrying particle that could allow multiple doses of a drug or vaccine to be delivered over an extended time period with just one injection.

The new microparticles resemble tiny coffee cups that can be filled with a drug or vaccine and then sealed with a lid. The particles are made of a biocompatible, FDA-approved polymer that can be designed to degrade at specific times, spilling out the contents of the "cup."

Free-standing carbon membranes that are a millionth of a millimetre thin: these are a special research field of Professor Dr. Armin Gölzhäuser from Bielefeld University and his research group. The nanomembranes can serve as ultrafine filters and as a protective layer. The Bielefeld physicists have registered several patents for manufacturing such molecular foils. In their research, they are analysing which properties the nanomembranes possess - as a basis for future applications.

The security of wearable fitness trackers could be improved to better protect users' personal data, a study suggests.

Vulnerabilities in the devices - which track heart rate, steps taken and calories burned - could threaten the privacy and security of the data they record, scientists say.

Exploiting security weak spots in the communication procedures of some gadgets could allow unauthorised sharing of personal data with third parties. These include online retailers and marketing agencies, the team says.

Self-healing materials are able to repair autonomously defects, such as scratches, cracks or dents, and resume their original shape. For this purpose, they must be composed of several components whose combined properties result in the desired characteristics. Scientists of the Karlsruhe Institute of Technology (KIT) and the Technion - Israel Institute of Technology now discovered that also tiny particles of pure gold have surprising self-healing capacities.

A prototype software application, to be used with the optical head-mounted display Google Glass, has been designed as a social-skills coach for children with autism spectrum disorder (ASD).
