Wine labels with animals: Why they work

Traditional brand research argues that logos should be highly relevant to the product they represent in order to be successful. However, marketers have recently begun using unusual visual identifiers that have little, if anything, to do with the product. For example, market research firm ACNielsen reports that nearly one in five of the table-wine brands introduced in the last three years features an animal on the label. A forthcoming study in the April 2008 issue of the Journal of Consumer Research reveals why this tactic is works.

"To our knowledge, this is the first experimental demonstration of the beneficial effects of unique visual identifiers that are not meaningfully related to the nature of the product," write Aparna A. Labroo (University of Chicago), Ravi Dhar (Yale University), and Norbert Schwarz (University of Michigan).

Does touch affect flavor? Study finds that how a container feels can affect taste

Does coffee in a flimsy cup taste worse than coffee in a more substantial cup? Firms such as McDonalds and Starbucks spend millions of dollars every year on disposable packaging, but a new study from the April issue of the Journal of Consumer Research suggests that trying to skimp in this area might not be worth it - and may negatively impact consumers' perceptions of taste and quality.

In a series of four experiments, Aradhna Krishna (University of Michigan) and Maureen Morrin (Rutgers University) find that many people do indeed judge a drink by its container. Specifically, the firmness of a cup seems to have an impact on consumer evaluations of the beverage contained inside.

Ukraine: Brain surgeon operates with DIY drill

An eminent British neuro-surgeon has been performing complex brain operations using a £30 do-it-yourself cordless power drill at a clinic in Ukraine.

Henry Marsh, a senior consultant at St George's hospital in Tooting, south London, has used the Bosch 9.6 volt battery-operated hand tool to open up the skulls of his patients to remove life-threatening tumours. Occasionally the battery has gone flat halfway through.

Scotland: Valium Nation

It gained notoriety in the 1960s as mother's little helper'' ... but now Valium is Scotland's hidden drugs scourge, affecting thousands from all sectors of society.

An investigation by the Sunday Herald has revealed a shocking picture of the scale of use of powerful tranquillisers known as benzodiazepines. Those abusing the drug range from heroin addicts to middle-class cocaine users, while others have unwittingly become hooked for decades after being prescribed the medication by doctors.

Illicit supplies of the drug are also flooding in to Scotland from abroad, and it can be bought on the streets for as little as 50p, as well as being easily obtained over the internet.

Valium, which is now prescribed under its generic name diazepam, is one benzodiazepine. This drug group is used to help overcome anxiety and sleep deprivation, but can lead to addiction and horrific withdrawal symptoms.

Depression: the symptoms in children are not like in adults

Depression is not always manifested in children as dejection and anhedonia. Depending on the age of the child, the dominant features may be weeping, irritability or defiance, as explained by Prof. Claudia Mehler-Wex and Dr. Michael Kölch of Ulm University in the new edition of Deutsches Ärzteblatt International (Dtsch Arztebl Int 2008; 105(9): 149-55).

The signs of depression in infants are often screaming, restlessness, and weeping attacks for no clear reason. Preschool children may behave irritably and aggressively, while schoolchildren may be listless and apathetic. The symptoms in adolescents become similar to those in adults.

Researchers discover second depth-perception method in brain

It's common knowledge that humans and other animals are able to visually judge depth because we have two eyes and the brain compares the images from each. But we can also judge depth with only one eye, and scientists have been searching for how the brain accomplishes that feat.

Now, a team led by a scientist at the University of Rochester believes it has discovered the answer in a small part of the brain that processes both the image from a single eye and also with the motion of our bodies.

The team of researchers, led by Greg DeAngelis, professor in the Department of Brain and Cognitive Sciences at the University of Rochester, has published the findings in the March 20 online issue of the journal Nature.

"It looks as though in this area of the brain, the neurons are combining visual cues and non-visual cues to come up with a unique way to determine depth," says DeAngelis.

Cup Of Black Tea Could Defend Against Anthrax Threat, Research Suggests

A cup of black tea could be the next line of defence in the threat of bio-terrorism according to new international research.A new study by an international team of researchers from Cardiff University and University of Maryland has revealed how the humble cup of tea could well be an antidote to Bacillus anthracis --more commonly know as anthrax.

As a nation, Brits currently drink 165 million cups of tea, and the healing benefits of the nation's favourite beverage have long been acknowledged.

A cup of black tea could be the next line of defence in the threat of bio-terrorism according to new international research.

But now the team of scientists led by Professor Les Baillie from Welsh School of Pharmacy at Cardiff University and Doctor Theresa Gallagher, Biodefense Institute, part of the Medical Biotechnology Centre of the University of Maryland Biotechnology Institute in Baltimore, has found that the widely-available English Breakfast tea has the potential to inhibit the activity of anthrax, as long as it is black tea.
