How anti-depressants and cocaine interact with brain

In a first, scientists from Weill Cornell Medical College and Columbia University Medical Center have described the specifics of how brain cells process antidepressant drugs, cocaine and amphetamines. These novel findings could prove useful in the development of more targeted medication therapies for a host of psychiatric diseases, most notably in the area of addiction.

Hyperactive immune resistance brings blindness in old age

Age-dependent macular degeneration (AMD) is the commonest cause of blindness in the western industrialised nations. Hereditary changes in the regulation of the immune system influence the risk of contracting AMD.

Suprising finding on aging

Age may not be rust after all. Specific genetic instructions drive aging in worms, report researchers at the Stanford University School of Medicine. Their discovery contradicts the prevailing theory that aging is a buildup of tissue damage akin to rust, and implies science might eventually halt or even reverse the ravages of age.

Researchers find key mechanism of cell damage in aging and disease

Researchers have taken a first snapshot of how a class of highly reactive molecules inflicts cellular damage as part of aging, heart disease, stroke, cancer, diabetes, kidney disease and Alzheimer's disease to name a few. According to a study published today in the journal Cell, researchers have discovered a tool that can monitor related damage and determine the degree to which antioxidant drugs effectively combat disease.

Tethered bilayer membrane may unlock secrets of early-stage Alzheimer's

Researchers at the National Institute of Standards and Technology (NIST) and three collaborating institutions are using a new laboratory model of the membrane surrounding neurons in the brain to study how a protein long suspected of a role in early-stage Alzheimer's disease actually impairs a neuron's structure and function.

The brain under pressure: Bristol Neuroscience attracts BBSRC grant

The Biotechnology and Biological Sciences Research Council (BBSRC) has awarded a grant of over £0.5 million to groups in the Laboratories for Integrative Neuroscience and Endocrinology and the MRC Centre for Synaptic Plasticity (project leader, Professor Kei Cho). The funding will support research into how brain cells maintain their performance, and create memories, during periods of acute stress.

Can knowledge of objects be used to identify color?

One of the easiest ways to identify an object is by its color -- perhaps it is because children's books encourage us to pair certain objects with their respective colors. Why else would so many of us automatically assume carrots are orange, grass is green and apples are red?

Notch protein helps human embryonic stem cells 'decide' their own fate

Researchers at Johns Hopkins have discovered that the Notch protein helps human embryonic stem cells 'decide' their own fate, a finding which may eventually be useful in programming cells for the development of stem cell therapies. Their results are reported in the May 2008 issue of Cell Stem Cell.

Science of magic - understanding human cognition and perception

Magic tricks, like those by Derren Brown and David Blaine, should be studied more closely to gain a deeper knowledge of the way human beings think and act, according to research by British and Canadian psychologists.

Discovery of cells for spinal-cord repair

A researcher at MIT's Picower Institute for Learning and Memory has pinpointed stem cells within the spinal cord that, if persuaded to differentiate into more healing cells and fewer scarring cells following an injury, may lead to a new, non-surgical treatment for debilitating spinal-cord injuries.

Discovery of new anatomical path through which the brain and spleen communicate

In a major step in understanding how the nervous system and the immune system interact, scientists at The Feinstein Institute for Medical Research have identified a new anatomical path through which the brain and the spleen communicate.
