Many people with diabetes continue to smoke despite being at high risk of cardiovascular disease. We examined the impact of a pay-for-performance incentive in the United Kingdom introduced in 2004 as part of the new general practitioner contract to improve support for smoking cessation and to reduce the prevalence of smoking among people with chronic diseases such as diabetes.

Large boards and store displays already exist as prototypes. They talk to you directly, using digital information embedded in the paper. You simply touch various parts of the display to get information to stream out of printed speakers.

Research teams at the Mid Sweden University forestry industry research program Fiber Science and Communication Network (FSCN) are working on the fourth generation of products that integrate paper with the digital world.

Scientists exploring the remote highlands of eastern Suriname discovered 24 species believed to be new to science, including an Atelopus frog with brilliant purple markings, four Eleutherodactylus frog species, six species of fish, 12 dung beetles and an ant species.

Why does foreign money often feel like play money to travelers" Just in time for summer vacation season, an important new study from the June issue of the Journal of Consumer Research examines why spending patterns abroad deviate so much from what we spend at home.

What you buy says a lot about you, according to a new study from the June issue of the Journal of Consumer Research. Consider this goal: to spend more time with your family. If you seek out products that expand the amount of quality time you have to share – say, a football to throw around in the yard – you’re a “promotion-focused” consumer. Alternatively, if you are “prevention-focused,” you’ll seek out timesavers, like a new dishwasher, that don’t reduce the amount of time you have to spend with your family.

University of Utah physicists developed small devices that turn heat into sound and then into electricity. The technology holds promise for changing waste heat into electricity, harnessing solar energy and cooling computers and radars.

The majority of doctors in North Carolina do not probe for signs of postpartum depression in new mothers, according to a survey conducted by researchers at the University of North Carolina at Chapel Hill.

Of the 228 physicians responding to the survey who said they had seen women for postpartum visits in the previous three months, 79 percent said they were unlikely to formally screen the patients for depression. An estimated 13 percent of new mothers are affected by postpartum depression.

Belgian mathematician hopes to use the science of chaos, the butterfly effect and strange attractors to help build a complete model of climate and resources that will lead to a new approach to sustainable development.

Scientists at the University of Liverpool have found that humans’ ability to walk upright developed from ancestors foraging for food in forest tree tops and not from walking on all fours on open land.

It was traditionally thought that humans became upright walkers in a slow process which had its origins in ‘knuckle-walking’ – movement on all fours – just as chimpanzees and gorillas walk today. It was believed that this developed once human ancestors moved out of the forests into the savannahs of East Africa.

NASA and Columbia University Earth Institute research finds that human-made greenhouse gases have brought the Earth’s climate close to critical tipping points, with potentially dangerous consequences for the planet.

From a combination of climate models, satellite data, and paleoclimate records the scientists conclude that the West Antarctic ice sheet, Arctic ice cover, and regions providing fresh water sources and species habitat are under threat from continued global warming.
