Medicine articlesHow to recognize visual objects
In work that could aid efforts to develop more brain-like computer vision systems, MIT neuroscientists have tricked the visual brain into confusing one object with another, thereby demonstrating that time teaches us how to recognize objects.
Real-world behavior and biases show up in virtual world
Americans are spending increasing amounts of time hanging around virtual worlds in the forms of cartoon-like avatars that change appearances according to users' wills, fly through floating cities in the clouds and teleport instantly to glowing crystal canyons and starlit desert landscapes.
Some political views may be related to physiology
People who react more strongly to bumps in the night, spiders on a human body or the sight of a shell-shocked victim are more likely to support public policies that emphasize protecting society over preserving individual privacy. That's the conclusion of a recent study by researchers at the University of Nebraska-Lincoln (UNL). Their research results appear in the Sept. 19 issue of Science magazine.
Baby eyes are taking in the world, applying self-experience to other people
Those wide-eyed babies are taking in and using more information than previously believed.
New study will make criminals sweat
The inventor of a revolutionary new forensic fingerprinting technique claims criminals who eat processed foods are more likely to be discovered by police through their fingerprint sweat corroding metal.
Being too clean may cause type 1 diabetes
'Friendly' bacteria help to stop the development of Type 1 diabetes, according to new research published online in Nature.
During exercise, the human brain shifts into high gear on 'alternative energy'
Alternative energy is all the rage in major media headlines, but for the human brain, this is old news. According to a study by researchers from Denmark and The Netherlands published in the October 2008 print issue of The FASEB Journal, the brain, just like muscles, works harder during strenuous exercise and is fueled by lactate, rather than glucose.
Short rnas show a long history
MicroRNAs, the tiny molecules that fine-tune gene expression, were first discovered in 1993. But it turns out they've been around for a billion years.
New findings indicate HIV/AIDS pandemic began around 1900, earlier than previously thought
New research indicates that the most pervasive global strain of HIV began spreading among humans between 1884 and 1924, not during the 1930s, as previously reported.
When seeing is believing
New research published in the journal Science explains why individuals seek to find and impose order on an unruly world through superstition, rituals and conspiratorial explanations by linking a loss of control to individual perceptions. The research finds that a quest for structure or understanding leads people to trick themselves into seeing and believing connections that simply don't exist.
Car or pedestrian -- How we can follow objects with our eyes
When an object moves fast, we follow it with our eyes: our brain correspondingly calculates the speed of the object and adapts our eye movement to it. This in itself is an enormous achievement, yet our brain can do even more than that. In the real world, a car will typically accelerate or brake faster than, say, a pedestrian. But the control of eye movement in fact responds more sensitively to changes in the speed of fast moving objects than slow moving objects.
Musicians use both sides of their brains more frequently than average people
Supporting what many of us who are not musically talented have often felt, new research reveals that trained musicians really do think differently than the rest of us. Vanderbilt University psychologists have found that professionally trained musicians more effectively use a creative technique called divergent thinking, and also use both the left and the right sides of their frontal cortex more heavily than the average person.
Research team discovers brain pathway responsible for obesity
University of Wisconsin-Madison researchers, for the first time, have found a messaging system in the brain that directly affects food intake and body weight.
A fine balance
Once a toddler has mastered the art of walking, it seems to come naturally for the rest of her life. But walking and running require a high degree of coordination between the left and right sides of the body. Now researchers at the Salk Institute for Biological Studies have shown how a class of spinal cord neurons, known as V3 neurons, makes sure that one side of the body doesn't get ahead of the other.
Risk and reward compete in brain
That familiar pull between the promise of victory and the dread of defeat - whether in money, love or sport - is rooted in the brain's architecture, according to a new imaging study.
RNA molecules, delivery system improve vaccine responses, effectiveness
A novel delivery system that could lead to more efficient and more disease-specific vaccines against infectious diseases has been developed by biomedical engineers at The University of Texas at Austin.
Narcissistic people most likely to emerge as leaders
When a group is without a leader, you can often count on a narcissist to take charge, a new study suggests.
Smoking and solid-fuel-burning in homes in China projected to cause millions of deaths
If current levels of smoking and biomass and coal fuel use in homes continues, between 2003 and 2033 there will be an estimated 65 million deaths from chronic obstructive pulmonary disease (COPD) and 18 million deaths from lung cancer in China, accounting for 19% and 5% of all deaths in that country during this period.
Duke team explains a longtime visual puzzler in new way
A team of neuroscientists at Duke University Medical Center has suggested an entirely new way to explain a puzzling visual phenomenon called the flash-lag effect.
Facial expressions say more than a thousand words
People talk to exchange information. Yet understanding another person involves far more than just the content of the message. Only with the correct intonation and facial expression does the message acquire meaning. People can improve their communication skills by deliberately managing these non-verbal messages.
