Medicine articlesPlatypus genome decoded
The curious discovery of the duck-billed, egg-laying, otter-footed, beaver-tailed, venomous platypus in Australia in 1798 convinced British scientists that it must be a hoax. Sketches of its appearance were thought to be impossible.
Gene sequence that can make half of us fatter is discovered
A gene sequence linked to an expanding waist line, weight gain and a tendency to develop type 2 diabetes has been discovered as part of a study published in the journal Nature Genetics.
Biochips can detect cancers before symptoms develop
In their fight against cancer, doctors have just gained an impressive new weapon to add to their arsenal. Researchers at the U.S. Department of Energy's Argonne National Laboratory have developed a chip that can save lives by diagnosing certain cancers even before patients become symptomatic.
Kids think eyeglasses make other kids look smart
Young children tend to think that other kids with glasses look smarter than kids who don't wear glasses, according to a new study.
Justice in the brain: equity and efficiency are encoded differently
Which is better, giving more food to a few hungry people or letting some food go to waste so that everyone gets a share? A study appearing in Science finds that most people choose the latter, and that the brain responds in unique ways to inefficiency and inequity.
Blocked brain enzyme decreases appetite and promotes weight loss
Imagine being able to tone down appetite and promote weight loss, while improving the body's ability to handle blood sugar levels.
With age comes a sense of peace and calm
Aging brings a sense of peace and calm, according to a new study from the Population Research Center at The University of Texas at Austin. Starting at about age 60, participants reported more feelings of ease and contentment than their younger counterparts.
Sleep deprivation affects ability to make sense of what we see
Neuroscience researchers at the Duke-NUS Graduate Medical School in Singapore have shown for the first time what happens to the visual perceptions of healthy but sleep-deprived volunteers who fight to stay awake, like people who try to drive through the night.
Sight recovery after blindness offers new insights on brain reorganization
Studies of the brains of blind persons whose sight was partially restored later in life have produced a compelling example of the brain's ability to adapt to new circumstances and rewire and reconfigure itself.
Researchers reveal the neuronal computations governing strategic social interactions in the human brain
In a strategic game, the success of any player depends not just on his or her own actions, but on the behavior of every other player in the game. To be successful, players must not only pay attention to what other players do, but also how they are thinking.
Insulin pill possibilities starting to gel; engineer reports significant progress
Insulin pills to replace the injections necessary for those suffering from diabetes appear closer to reality through new research by chemical and biomedical engineers at The University of Texas at Austin.
Preserving skin elasticity could unlock secrets for better body health
University of Manchester scientists have begun a study to understand the decline of 'springiness' in our bodies' skin and tissues as we get older.
Mixed feelings not remembered as well as happy or sad ones
Imagine you're about to step onto a rollercoaster at an amusement park. You are filled with apprehension and joy, mixed emotions that last beyond the dizzying ride. How will you remember the experience?
Are you a different person when you speak a different language?
People who are bicultural and speak two languages may actually shift their personalities when they switch from one language to another, according to new research in the Journal of Consumer Research.
Why do people vote? Genetic variation in political participation
A groundbreaking new study finds that genes significantly affect variation in voter turnout, shedding new light on the reasons why people vote and participate in the political system.
What it's like to be a bat
Not many people think about what it's like to be a bat, but for those who do, it's enlightening and potentially groundbreaking for understanding aspects of the human brain and nervous system.
Researchers develop neural implant that learns with the brain
Devices known as brain-machine interfaces could someday be used routinely to help paralyzed patients and amputees control prosthetic limbs with just their thoughts. Now, University of Florida researchers have taken the concept a step further, devising a way for computerized devices not only to translate brain signals into movement but also to evolve with the brain as it learns.
Mechanism and function of humour identified by new evolutionary theory
A new publication answers centuries' old questions regarding the mechanism and function of humour, identifying the reason humour is common to all human societies, its fundamental role in the evolution of homo sapiens and its continuing importance in the cognitive development of infants.
Woman aquires new accent after stroke
A woman in southern Ontario is one of the first cases in Canada of a rare neurological syndrome in which a person starts speaking with a different accent, McMaster University researchers report in the July issue of the Canadian Journal of Neurological Sciences.
Alzheimers disease as a case of brake failure?
Rutgers researcher Karl Herrup and colleagues at Case Western Reserve University have discovered that a protein that suppresses cell division in brain cells effectively "puts the brakes" on the dementia that comes with Alzheimer's disease (AD). When the brakes fail, dementia results.
