Modern technology helps shed light on illnesses in artists of the past
Illnesses, drugs and chemicals have influenced the artistic achievements of many of the world's best-known composers, classical painters, authors and sculptors. The associations between these elements and art may be close and many, and the tools of modern technology, including the use of clinical laboratory analysis, are providing further insights into this interaction.
Researcher uncovers new gene for fear factor
Rutgers geneticist Gleb Shumyatsky has discovered a gene that controls both innate and learned forms of fear. The gene, known as Stathmin or Oncoprotein 18, is highly concentrated in the amygdala, a key region of the brain that deals with fear and anxiety.
Researchers combine tiny nanotubes and antibodies to detect cancer
By coating the surfaces of tiny carbon nanotubes with monoclonal antibodies, biochemists and engineers at Jefferson Medical College and the University of Delaware have teamed up to detect cancer cells in a tiny drop of water. The work is aimed at developing nanotube-based biosensors that can spot cancer cells circulating in the blood from a treated tumor that has returned or from a new cancer.
World-first test of sun-damaged skin launched
A world-first test that assesses the damage people have done to their skin through sun exposure is being launched to the public at clinics throughout the UK.
Scientists find first evidence of a living memory trace
An international team of scientists for the first time has detected a memory trace in a living animal after it has encountered a single, new stimulus. The research, done with honeybees sensing new odors, allows neuroscientists to peer within the living brain and explore short-term memory as never before, according to scientist Roberto Fernández Galán, a leading author on the report who is currently a postdoctoral research associate at Carnegie Mellon University.
New research links consumer behavior to the weather
It's a sun-drenched weekend afternoon. You're at a music store listening to demo CDs and happily watching the world go by outside the store's window. Consequently, you leave the store with a load of CDs. But did the music grab you? Or was it the weather? A new study in the Journal of Consumer Research suggests you are the proud owner of those CDs not because you fell in love with them as much as because you were simply having a good day.
Scientists work to discover how music training affects the brain
New research shows that the special training of music conductors seems to enhance the way their senses work together – enabling them to quickly tell who played a wrong note, for example. Scientists hope the research will lead to new discoveries about how music training may change the brain.
Comic books shadow how we react to threats
In times of social danger and economic turmoil, many psychologists believe that people become more aggressive, more conventional, and less interested in feelings and emotions. A new study published in the latest issue of Political Psychology finds that comic book characters do these things as well.
Riding roller coasters may actually be 'death-defying' for people with heart disease
The thrill of a roller coaster ride with its climbs, loops and dives can speed up the heart, sparking off an irregular heartbeat that could put individuals with heart disease at risk of having a cardiovascular event, according to new research reported at the American Heart Association's Scientific Sessions 2005.
Research permits first-ever visualization of psychological stress in the human brain
Using a novel application of an fMRI (functional magnetic resonance imaging) technique, researchers at the University of Pennsylvania School of Medicine have, for the first time, visualized the effects of everyday psychological stress in a healthy human brain.

Mildly depressed people more perceptive than others
Surprisingly, people with mild depression are actually more tuned into the feelings of others than those who aren't depressed, a team of Queen's psychologists has discovered.
Mental stress may be another culprit in raising cholesterol levels in healthy adults
There is good evidence to show that stress can increase a person's heart rate, lower the immune system's ability to fight colds and increase certain inflammatory markers but can stress also raise a person's cholesterol? It appears so for some people, according to a new study that examines how reactions to stress over a period of time can raise a person's lipid levels.
Sweat is good indicator heart attack may be coming
Sweating during physical activity or in hot weather is healthy. But when individuals begin perspiring while experiencing discomfort in their chest, arm, neck or jaw -- with little or no exertion -- it could be the onset of a heart attack, according to a new study at the University of Illinois at Chicago.
Discovery disproves simple concept of memory as 'storage space'
Even if you could get more RAM for your brain, the extra storage probably wouldn't make it easier for you to find where you left your car keys.
Major study links chronic noise exposure to risk of heart attacks
Research published online in European's leading cardiology journal, European Heart Journal, links exposure to chronic noise with an increased risk of heart attack.
Potential malaria drug target identified
Researchers have identified an enzyme crucial to the malaria parasite's invasion of red blood cells, according to a study in the open-access journal, PLoS Pathogens.
Swimming with dolphins can alleviate depression
Swimming with dolphins is an effective treatment for mild to moderate depression, say researchers in this week's BMJ.
Getting close to nature is good for you
Connecting with nature can improve your health and wellbeing, say researchers in this week's BMJ. The theory is known as ecotherapy: restoring health through contact with nature.
Little gifts, big donations?
When charities enclose a few cards as presents with their appeals for help, this increases the volume of donations considerably. This has been established by researchers from the University of Bonn and the Institute for the Study of Labor in a field experiment.
Give thanks for the cranberry
Families gathered around the Thanksgiving dinner table might consider giving thanks for the bacteria-busting ability of cranberry juice, say dental researchers who have discovered that the beverage holds important clues for preventing cavities.
