Cell division studies hint at future cancer therapy

When a cell's assets get divided between daughter cells, Dr. Quansheng Du wants to make sure both offspring do well.

Stem cell research aims to tackle Parkinson's disease

Scientists in Sweden are developing new ways to grow brain cells in the laboratory that could one day be used to treat patients with Parkinson's disease, an international conference of biologists organised by the European Science Foundation (ESF) was told last week.

Sleep plays a critical role in the brain's ability to learn

Most people know it from experience: After so many hours of being awake, your brain feels unable to absorb any more-and several hours of sleep will refresh it.

Alzheimer's molecule is a smart speed bump on the nerve-cell transport highway

Researchers at the University of Pennsylvania School of Medicine discovered that proteins carrying chemical cargo in nerve cells react differently when exposed to the tau protein, which plays an important role in Alzheimer's disease.

New auditory cortex research may bring better hearing aids and more effective speech recognition systems

Recognising people, objects or animals by the sound they make is an important survival skill and something most of us take for granted.

A good night's sleep could improve long-term memory

Scientists from the Medical Research Council's Anatomical Neuropharmacology Unit (ANU) at the University of Oxford have discovered evidence that sleep is important for the stabilisation of memory.

Two different neural pathways regulate loss and regain of consciousness during general anesthesia

University of Pennsylvania School of Medicine researchers have answered long-running questions about the way that anesthetics act on the body, by showing that the cellular pathway for emerging from anesthesia is different from the one that drugs take to put patients to sleep during operations.

Ringing in the ears

Do your ears ring after a loud concert? Nerves that sense touch in your face and neck may be behind the racket in your brain, University of Michigan researchers say.

Auditory neurons in humans far more sensitive to fine sound frequencies than most mammals

The human ear is exquisitely tuned to discern different sound frequencies, whether such tones are high or low, near or far.

A few more pieces for the puzzle that is Alzheimer’s disease

Alzheimer's disease (AD) affects as much as 10% of the world population above 65 years of age but after years of research it is still not understood exactly how the disease appears and, even less, how to treat it.

Potential new treatments for Huntington's disease

Working with fruit flies, researchers have discovered a new mechanism by which the abnormal protein in Huntington's disease causes neurodegeneration.

Trichloroethylene exposure linked to Parkinsonism

Industrial workers who worked with trichloroethylene (TCE) may face a greater risk for parkinsonism, a study by a team of University of Kentucky researchers shows.

Blocking parasites' communication reduces infection

One of the most common human parasites, Toxoplasma gondii, uses a hormone lifted from the plant world to decide when to increase its numbers and when to remain dormant, researchers at Washington University School of Medicine in St. Louis have found.

Stress causes whole body deterioration

Stress, to put it bluntly, is bad for you. It can kill you, in fact. A study now reveals that stress causes deterioration in everything from your gums to your heart and can make you more susceptible to everything from the common cold to cancer.

Trichloroethylene chemical - widely used in industry - is a risk factor for parkinsonism

Parkinson's disease, the most common neurodegenerative movement disorder caused by aging, can also be caused by pesticides and other neurotoxins.

8 Jan 2008

Novel mechanism for long-term learning identified

Practice makes perfect - or at least that's what we're told as we struggle through endless rounds of multiplication tables, goal kicks and piano scales - and it seems, based on the personal experience of many, to be true.

Daily alcohol use causes changes in sexual behavior

A team of researchers at Penn Sate has used an animal model to reveal, for the first time, a physiological basis for the effect of alcohol on male sexual behavior, including increased sexual arousal and decreased sexual inhibition.

Effects of sleep deprivation reversed

Researchers at Wake Forest University School of Medicine have shown that the effects of sleep deprivation on cognitive performance can be reversed when the naturally occurring brain peptide, orexin-A, is administered in monkeys.

Epilepsy and brain pathology linked together by the protein ADK

The brain of individuals who suffer from epilepsy is characterized by astrogliosis, a brain pathology evidenced by a complex series of changes in the morphology and function of brain cells known as astrocytes.

Some antipsychotic drugs may be missing their mark

Drugs that treat depression, schizophrenia and other psychotic conditions and that target a particular protein on brain cells might not be triggering the most appropriate response in those cells, new research suggests.
