|  Smoking cessation experts weigh in on e-cigarettes  | With the third and largest of the U.S. tobacco companies planning an e-cigarette product launch this fall, this next frontier for "Big Tobacco" provides renewed presence in a declining marketplace. | Read More » Giving preschoolers choice increases sharing behavior  | Allowing children to make a choice to sacrifice their own toys in order to share with someone else makes them more likely to share in the future, according to new research. | Read More » Altruism or manipulated helping? Altruism may have origins in manipulation  | Manipulation is often thought of as morally repugnant, but it might be responsible for the evolutionary origins of some helpful or altruistic behavior, according to a new study. | Read More » Ringing the changes: What museum specimens reveal about climate change  | Butterflies collected as long ago as 1876 – the year Alexander Graham Bell made the world's first telephone call – are shedding new light on the earlier arrival of spring each year. Ecologists are using thousands of butterflies from museum collections to learn more about climate change. | Read More » Handaxe design reveals distinct Neanderthal cultures  | Researchers have found that Neanderthals were more culturally complex than previously acknowledged. Two cultural traditions existed among Neanderthals living in what is now northern Europe between 115,000 to 35,000 years ago. Researchers examined the design of 1,300 stone tools originating from 80 Neanderthal sites in five European countries; France, Germany, Belgium, Britain and the Netherlands. They uncovered new evidence that two separate handaxe traditions or designs existed - one in a region now spanning south-western France and Britain - the other in Germany and further to the East. | Read More » Species diversification in biodiversity hotspots  | Biodiversification isn't always favored by living in a hotspot of biodiversity, suggests a study of Australian wood shrubs. The finding goes against previous thinking and boosts our understanding of the factors driving biodiversity. A common view is that species in biodiversity hotspots diversify more quickly than species in less biodiverse areas. But that's not the case for the spikey-flowered Banksia. | Read More » Quadcopter piloted by a smartphone  | A new quadcopter can negotiate its way through a room completely on its own. It does not need any human interference, and in contrast to other models, it is not assisted by any external computer. All the necessary computing power in on board; the image processing is done by a standard smartphone. | Read More » Future flood losses in major coastal cities: Costly projections  | Climate change combined with rapid population increases, economic growth and land subsidence could lead to a more than nine-fold increase in the global risk of floods in large port cities between now and 2050. | Read More » Longest and largest study of insulin pumps to treat type 1 diabetes in children shows they control blood sugar more effectively and with fewer complications than injections  | The longest and largest study of the effectiveness of insulin pumps to treat type 1 diabetes in children has shown that the pumps are more effective at controlling blood sugar than insulin injections and cause fewer complications. | Read More » New MR analysis technique reveals brain tumor response to anti-angiogenesis therapy  | A new way of analyzing data acquired in MR imaging appears to be able to identify whether or not tumors are responding to anti-angiogenesis therapy, information that can help physicians determine the most appropriate treatments and discontinue ones that are ineffective. | Read More » Major study links aging gene to blood cancer  | A gene that helps control the ageing process by acting as a cell's internal clock has been linked to cancer by a major new study. Scientists found a genetic variant that influences the ageing process among four new variants they linked to myeloma -- one of the most common types of blood cancer. The study more than doubles the number of genetic variants linked to myeloma. | Read More » Dialing back Treg cell function boosts cancer-fighting immune activity  | By carefully adjusting the function of crucial immune cells called Tregs, scientists may have developed a completely new type of cancer immunotherapy—harnessing the body's immune system to attack tumors. | Read More » Waking up to a new year: Exoplanet orbits its star in 8.5 hours  | In the time it takes you to complete a single workday, or get a full night's sleep, a small fireball of a planet 700 light-years away has already completed an entire year. Researchers have discovered an Earth-sized exoplanet named Kepler 78b that whips around its host star in a mere 8.5 hours -- one of the shortest orbital periods ever detected. | Read More » Equipping a construction helmet with a sensor can detect the onset of carbon monoxide poisoning  | Researchers integrated a specific type of sensor into a typical construction helmet to allow continuous and noninvasive monitoring of construction workers' blood gas saturation levels. The results of their study showed that a user of this helmet would be warned of impending carbon monoxide poisoning with a probability of greater than 99 percent. | Read More » Computer can read letters directly from the brain  | By analysing MRI images of the brain with an elegant mathematical model, it is possible to reconstruct thoughts more accurately than ever before. In this way, researchers have succeeded in determining which letter a test subject was looking at. | Read More » | |
