Doctors develop new measures for bone disease
As we age we can expect to shrink an average of three to four centimetres. Such loss is normal due to shrinkage of the disks within the spine.
Study shows brain can manipulate taste
As the prism of our senses, the human brain has ways of refracting sensory input in defiance of reality.
Brain researchers discover the evolutionary traces of grammar
The bases of the human language faculty are now being investigated by means of highly specialised measurement techniques and with increasing success. Why can we understand complex sentences, while our nearest cousins - apes - only understand individual words?
Saliva test offers new window on caffeine/stress response
Penn State researchers have shown that a simple saliva test may offer a new way to probe the physical consequences of caffeine coupled with stress.
Researcher identifies brain activity that sets the stage for retaining memories
Researchers have identified the neural activity that occurs when the brain "sets the stage" for retaining a memory - a finding that could have important implications for memory research and help determine ways in which people can strengthen memories they want to retain while weakening ones they would rather forget.
Nature, nuture and the risk of depression
Some people are more than twice as likely to become depressed as others, given similar circumstances, according to landmark research from Brain Sciences UNSW.
New implanted contacts designed to fix nearsightedness
UT Southwestern Medical Center ophthalmologists will be the first in the area to insert a new type of implanted lens to fix nearsightedness.
Ancient DNA helps researchers unearth potential hemophilia therapy
A cut can be life-threatening for people with hemophilia, whose bodies don't produce enough of a protein that prevents prolonged bleeding.
Scientists show how brain processes sound
Scientists at Carnegie Mellon University have discovered that our ears use the most efficient way to process the sounds we hear, from babbling brooks to wailing babies. These results represent a significant advance in understanding how sound is encoded for transmission to the brain, according to the authors.
Neurons in sync focus attention
When individual neurons fire independently, their electrical recordings sound like radio static, all noise and no signal. When even a minority of neurons fire in synchrony, a tone emerges that resembles the one that precedes radio Emergency Broadcast System announcements.

Detection of DNA on nanotubes offers new sensing, sequencing technologies
Researchers at the University of Illinois at Urbana-Champaign who recently reported that DNA-wrapped carbon nanotubes could serve as sensors in living cells now say the tiny tubes can be used to target specific DNA sequences. Potential applications for the new sensors range from rapid detection of hazardous biological agents to simpler and more efficient forensic identification.
There's more than meets the eye in judging the size of an object
You can't always trust your eyes. Neuroscientists from the University of Washington and the University of Minnesota have found that the first area in the cortex of the human brain that receives information from the eyes processes the perceived size, rather than the actual size, of an object.
Recognizing others
Imagine seeing a former high school classmate you always wanted to know better. Then imagine seeing that kid who used to push you in the hallways. Do you react differently? What happens in your brain during these encounters?
Seaweed in novel diabetes treatment
A product made from seaweed is offering new hope to those with juvenile diabetes. It is part of a novel treatment, which was trialled in Australia for the first time on Monday 20 February by University of New South Wales (UNSW) researchers at the Prince of Wales Hospital and Community Health Services in Sydney.
Researchers find potential new target for autism, retardation therapies
An international team, led by neuroscientists at the University of British Columbia, have discovered the "on-off switch" that controls how chemical messages are exchanged in the brain, a finding that may lead to new therapies for autism, schizophrenia and mental retardation.
Mood affects young and old differently
The effect of mood on how people process information changes greatly as they age, suggests new research from the Georgia Institute of Technology. The study, which offers a window into the changing nature of the aging mind and the way it handles emotion and information, appears in the latest edition of the journal Psychology and Aging.
Research team identifies cause of memory loss
A research team that included members from The Johns Hopkins University and the University of Minnesota Medical School has for the first time identified a substance in the brain that is proven to cause memory loss. This identification gives drug developers a target for creating drugs to treat memory loss in patients with dementia.
Researchers restore vision in rodents blinded by brain damage
Rodents blinded by a severed tract in their brains' visual system had their sight partially restored within weeks, thanks to a tiny biodegradable scaffold invented by MIT bioengineers and neuroscientists.
You scratch my back, i'll scratch yours
It was once thought that only humans gestured to direct another person's attention, but such "referential" gesturing was recently observed in wild chimpanzees.
Findings reveal possible Alzheimer's link to brain organ
Researchers have discovered that an organ in the brain called the choroid plexus apparently plays a critical role in preventing the accumulation of a protein associated with Alzheimer's disease.
