It's a lot easier to keep a customer than to get a new one, at least that's how the sales force maxim goes. So what then does the newly released J.D. Power and Associates 2012 Customer Retention Study say about the automotive brands and their ability to sell the same customer another car. For starters, something incredibly positive is happening at Hyundai - just two years ago, Hyundai was below the industry average in customer retention - now the Korean brand has flown past Mercedes, BMW, Porsche, Lexus, Infiniti and Acura to become the stickiest brand in the business. Which isn't hard - one in two motorists defects to another brand with their next purchase. Read More

A duck pond may seem like the ideal place to spend a peaceful spring afternoon, but during mating season it can look like the scene of a gang attack. Though ducks as a species are famously monogamous, unattached drakes can be extremely aggressive. They attack any female in sight in a mating frenzy that often ends in the injury or death of the victim. This has resulted in the ducks developing ways to prevent unwanted matings and the drakes ways to overcome their defenses. Researchers in North America are developing a novel way to study this "evolutionary arms race" that uses high-speed cameras, force transducers and model duck oviducts made of glass. Read More

Microscopic worm Caenorhabditis elegans may hold clues to the human colonization of space, according to scientists at The University of Nottingham. Research published by the university today indicates that C. elegans can reach maturity from egghood and successfully reproduce in space, just as it does on Earth. Now the worm is a prime candidate to form an advance party to Mars in order to examine the effects of long-distance space travel on earthly organisms. Read More

Developing true robot surrogates that allow you to be in two places at once means duplicating all of our movements and senses in machine form. Given you can now make a video call on your phone, it's fair to say we have the sight and sound aspects pretty well covered, but the challenge of adding touch to the equation is formidable. The TELESAR V Robot Avatar shows just how far we've come in turning into telepresence into telexistence - it's a humanoid remotely controlled robot that boasts a wide range of movement along with the ability to transmit sight, hearing and touch sensations to its operator via a set of sensors and 3D head mounted display.

Matthew Bailes is Pro-Vice Chancellor (Research) of the Swinburne University of Technology in Melbourne, Australia, and was one of the scientists responsible for the discovery of the diamond planet which received widespread news coverage over the last few weeks. In a well-penned article, Bailes discusses the reaction to the discovery and raises some very interesting questions about the way the scientific method is used and abused by the media. Read More

Over the last decade, mobile telephones have gone from being a rarity in most countries, to being carried by the vast majority of human beings. Now, according to new research, smartphone (which is actually a misnomer – it is actually a Very Personal Computer) sales will top a billion units a year by 2015 as the smartphone's share of phone shipments rockets from 15.8% in 2009, to 32.5% this year to 54.4% in 2015). Planet Earth only has 6.75 billion human inhabitants. If this trend continues, by the turn of the decade, the vast majority of human beings will be carrying a networked personal computer on their person at all times. We are undoubtedly living through a period of unprecedented change in human history. Read More

Mathematicians are creating their own version of the periodic table that will provide a vast directory of all the possible shapes in the universe across three, four and five dimensions, linking shapes together in the same way as the periodic table links groups of chemical elements. The three-year project, announced today, should provide a resource that mathematicians, physicists and other scientists can use for calculations and research in a range of areas, including computer vision, number theory, and theoretical physics. For some mental exercise, check out these animations that have already been analyzed in the project. Read More

A team of researchers from North Carolina State University claim to have created a memory device that could give computer users the speed advantages of DRAM system memory and the data retention capabilities of flash memory, in one unit. The new device could lead to genuine instant-on computing and machines with improved resiliency. The development may even lead to power-hungry server farms making considerable energy savings by allowing parts of the system to be shut down during periods of inactivity without fear of data loss.

We all know that certain pieces of music can evoke strong emotional responses in people. Now, a research team from Canada's McGill University has uncovered evidence that reveals exactly what causes such feelings of euphoria and ecstasy and why music is so important in human society. Using a combination of brain scanning technologies, the study has shown that the same neurotransmitter which is associated with feeling pleasure from sex and food is released in the brain when listening to good music.
