New way to prevent macular degeneration

Two studies from an unusual research partnership at the University of Chicago appear to have resolved a long-standing dispute about the role of melanin in the eye. The studies, one published in the Proceedings of the National Academy of Sciences (PNAS) and one early online in the Journal of the American Chemical Society (JACS), also suggest a new way to prevent a common cause of blindness.

Potential use of NH neurotransmitters as novel source for psychiatric drugs

Physiologists and medical researchers have long recognized the important endocrine roles played by the pituitary hormones oxytocin (OT) and vasopressin (VP) on peripheral systems in lactation, uterine contraction and urine concentration.

One of the first studies to define how unique we are on the genetic level

We all share the same genetic code, but a team from the Institute of Food Research (IFR) has found that the way our genes function varies significantly between individuals, particularly in some key areas including the immune system.

Diagnosing diabetes early saves lives

Australian Medical Association (AMA) President, Dr Mukesh Haikerwal, said today that while 520,000 Australians have been diagnosed with diabetes, there are probably as many again who remain undiagnosed, exposing them to serious complications caused by the disease, including kidney disease, heart attacks and eye problems.

ACE inhibitors should be available at no cost to the 8 million Americans over age 65 who have diabetes

Nothing in life is free, the old saying goes. But maybe some things should be, according to a new University of Michigan Health System study.

Nerve cells can also release neurotransmitters outside of synapses

Every neurobiology textbook invariably states that nerve cells communicate with each other through synapses, the specialized cell-cell contacts found at the end of the cells' threadlike extensions. In the journal Science, researchers at the Salk Institute for Biological Sciences and the University of California at San Diego report that nerve cells, or neurons, may not have to rely on traditionally defined synapses to "talk" to each other.

Researchers gain better understanding of how nerves need to be reconnected after spinal cord injury

Nerve cells relay messages at blink-of-the-eye speeds by squirting chemicals called neurotransmitters across tiny gaps called synapses to awaiting message receptors. But lots of different receptors and neurotransmitters work simultaneously. Which goes where to send the proper message?

Research shows key difference between the eye's light-detecting system and the nose's odor-detecting system

Johns Hopkins scientists have uncovered new details of how smelly things create signals in the nose that eventually go to the brain. The findings raise issues about how the process involved has been described for many years in biology textbooks.

Our thirst for novelty begins in the eye itself

Researchers at Harvard University have found evidence that the retina actively seeks novel features in the visual environment, dynamically adjusting its processing in order to seek the unusual while ignoring the commonplace. The scientists report in this week's issue of the journal Nature on their finding that this principle of novelty-detection operates in many visual environments.

Sunscreen plays a much more important role than just protecting against sunburn

The number of nevi, or moles, a person has is known to be a strong predictor of the future risk of developing skin cancer, particularly melanoma, the most deadly form of the disease. This number also is believed to be affected by the amount of sun exposure an individual receives.
