The brain needs the middle ear to track depth
When you jaywalk, your ability to keep track of that oncoming truck despite your constantly changing position can be a lifesaver. But scientists do not understand how such constant updating of depth and distance takes place, suspecting that the brain receives information not just from the eye but also from the motion-detecting vestibular system in the middle ear.
A new analysis of a standard brain test may help predict dementia
Although Alzheimer's disease affects millions of people worldwide, there is no way to identify this devastating brain disease at its earliest stages when there still may be time to delay or even prevent the downward spiral into dementia. In research settings, scientists are using sophisticated tools like MRI and PET to distinguish characteristics of brain function and anatomy that indicate future problems, providing a sort of screening test for the brain.
Shift in brain's language-control site offers rehab hope
Scientists have found that the site in the brain that controls language in right-handed people shifts with aging--a discovery that might offer hope in the treatment of speech problems resulting from traumatic brain injury or stroke.
How the brain sorts babble into auditory streams
Known as "the cocktail party problem," the ability of the brain's auditory processing centers to sort a babble of different sounds, like cocktail party chatter, into identifiable individual voices has long been a mystery.
New posssibilities for flu antiviral and vaccine research emerge from 'Spanish flu' virus
The 1918 Spanish flu was a global disaster, killing an estimated 20 to 50 million people, many of them otherwise healthy adults. By partially reconstructing the Spanish flu virus, researchers have now discovered at least part of what made the virus so lethal, thus providing essential information for influenza drug and vaccine research.
Eyes may provide window for future strokes
Looking into our eyes may help doctors predict who is at risk for stroke. A new study found that people with changes in the small blood vessels in their eyes are more likely to later suffer a stroke than people without these signs.
Marine snail's neural network sheds light on the basis for flexible behavior
From snail to man, one of the hallmarks of the brain is the ease with which behavioral variants are generated--for example, humans can easily walk with different stride lengths or different speeds. By studying how a relatively simple motor network of the marine snail Aplysia produces variants of a particular feeding behavior, researchers have found that the ability to generate a large number of behavioral variants stems from the elegant hierarchical architecture of the brain's motor network.
Prof develops cancer nanobomb
University of Delaware researchers are opening a new front in the war on cancer, bringing to bear new nanotechnologies for cancer detection and treatment and introducing a unique nanobomb that can literally blow up breast cancer tumors.
Pillows – A hot bed of fungal spores
Researchers at The University of Manchester funded by the Fungal Research Trust have discovered millions of fungal spores right under our noses – in our pillows.
Asthmatic cats may be allergic to humans
In a complete turnaround, instead of pets being blamed for causing allergies and breathing problems amongst people, human lifestyles are potentially triggering asthma attacks in cats. Cigarette smoke, dusty houses, human dandruff, pollen and certain types of cat litters can all create inflammation in cats' airways and worsen asthma.

Your brain cells may 'know' more than you let on by your behavior
We often make unwise choices although we should know better. Thunderstorm clouds ominously darken the horizon. We nonetheless go out without an umbrella because we are distracted and forget. But do we?
Tuberculosis, infertility may have influenced George Orwell's writing
The author of such portentous works as Animal Farm and 1984 may have been influenced by his own physical ailments, such as tuberculosis and infertility, in writing his gloomy portrayals of the future, according to an article in the Dec. 1 issue of Clinical Infectious Diseases, now available online.
Humans are governed by emotions-literally
The emotional responses that guide much of human behavior have a tremendous impact on public policy and international affairs, prompting government officials to make decisions in response to a crisis--such as the Sept. 11 terrorist attacks--with little regard to the long-term consequences, according to a study by scholars at Carnegie Mellon University and the University of Pittsburgh School of Law.
How labels shape our attitudes toward violence
What difference does it make if a prosecutor describes a defendant as a "murderer" or as "someone who commits murder?" In some cases, those few words could mean the difference between life and death.
New genetic link to high blood pressure found
A new genetic discovery made by a University of Michigan team may help explain why some people develop high blood pressure and others don't -- and why some people's blood pressure increases as they age.
New antifreeze protein may allow longer storage of transplant organs
A new antifreeze protein discovered in tiny snow fleas by Queen's University researchers may lengthen the shelf life of human organs for transplantation.
Autism problems explained in new research
New research from Melbourne's Howard Florey Institute helps to explain why children with autism spectrum disorders (autism) have problem-solving difficulties.
Study reveals reason women are more sensitive to pain than men
For centuries, it has been generally believed women are the more sensitive gender. A new study says that, when it comes to pain, women are in fact more sensitive.
Leeches provide source for cardiovascular drugs
The leech has recently confirmed its biomedical interest for scientists by showing that it contains an extensive list of new potential molecules that may become useful tools in the treatment of cardiovascular diseases.
Purdue's gold nanorods brighten future for medical imaging
Researchers at Purdue University have taken a step toward developing a new type of ultra-sensitive medical imaging technique that works by shining a laser through the skin to detect tiny gold nanorods injected into the bloodstream.
