Getting to the roots of hair loss
A healthy individual loses around a hundred hairs a day. Nothing to worry about as long as they are constantly replaced and the losses occur evenly around the whole scalp. view more (2008-02-25)
Australian study sheds light on kidney repair and disease
A study by Monash University researchers has shed new light on the microscopic antennas in the kidney that are involved in the organ's repair process. view more (2009-09-30)
USC researchers identify mechanism that controls activation of stem cells during hair regeneration
Researchers at the University of Southern California (USC) have identified a novel cyclic signaling in the dermis that coordinates stem cell activity and regulates regeneration in large populations of hairs in animal models. view more (2008-01-17)
Frozen hair holds secrets of Yellowstone grizzlies
Locks of hair from more than 400 grizzly bears are stored at Montana State University, waiting to tell the tale of genetic diversity in the Yellowstone Ecosystem. view more (2007-12-19)
Mouse Model Gives Insight to Human Hair Loss
A progressive skin disease causing hair loss in adult humans was identified in laboratory mice, providing a genetic tool to study the disease known as alopecia areata (AA). view more (2004-11-10)
Scientists link genetic pathway to development of hearing
Scientists are one step closer to understanding the genetic pathway involved in the development of hearing. view more (2005-08-19)
Researchers learn more about ways to regenerate the ear's hearing cells
Massachusetts General Hospital (MGH) researchers have made important progress in their ongoing effort to regenerate the inner ear's hair cells, which convert sound vibrations to nerve impulses. view more (2006-05-01)
New Study Looks At Sensitivity To Sun
A project designed to try and explain the way genes influence sensitivity to sun is underway at the University of Edinburgh. The study will look not only at the role of ultraviolet radiation in causing skin cancer, but at its benefits in treating of patients with psoriasis, eczema and a range of other skin conditions. Professor of Dermatology... view more... (2002-04-24)
Misconceptions about headlice: what does the research really show?
A review article in this week’s BMJ dispels some of the myths about treating head lice, using the most up-to-date medical research. For example, it shows that: view more (2003-06-04)
Now hear this
Deep in the ear, 95 percent of the cells that shuttle sound to the brain are big, boisterous neurons that, to date, have explained most of what scientists know about how hearing works. view more (2009-10-23)
Study shows isolation of stem cells may lead to a treatment for hearing loss
Have you ever walked by someone listening to their i-Pod loud enough for you recognize the song? Studies have shown noise-induced hearing loss is going to become the next big epidemic affecting our younger generation though the effects won't show until it is too late to treat. view more (2007-04-06)
Protein that controls hair growth also keeps stem cells slumbering
Like fine china and crystal, which tend to be used sparingly, stem cells divide infrequently. It was thought they did so to protect themselves from unnecessary wear and tear. view more (2008-01-25)

Stem Cells from Hair Follicles May Help
For a rich source of stem cells to be engineered into new blood vessels or skin tissue, clinicians may one day look no further than the hair on their patients' heads, according to new research published earlier this month by University at Buffalo engineers. view more (2008-03-31)
Amino acid may help treat patients with hair-pulling condition
The amino acid N-acetylcysteine appears to reduce symptoms of compulsive hair-pulling in patients with a condition known as trichotillomania. view more (2009-07-07)
One membrane, many frequencies
Modern hearing aids, though quite sophisticated, still do not faithfully reproduce sound as hearing people perceive it. New findings at the Weizmann Institute of Science shed light on a crucial mechanism for discerning different sound frequencies and thus may have implications for the design of better hearing aids. view more (2007-03-28)
St. Jude study solves mystery of mammalian ears
A 30-year scientific debate over how specialized cells in the inner ear amplify sound in mammals appears to have been settled more in favor of bouncing cell bodies rather than vibrating, hair-like cilia. view more (2007-07-30)
Levels of certain body chemicals may make us look older than we are
Levels of certain body chemicals seem to be associated with making us look older than we actually are, suggests research in the Postgraduate Medical Journal. But the type of chemicals differ in men and women, the study shows. The researchers focused on 447 London civil servants, of whom 129 were women. Chronological age ranged from 38 to 57. The... view more... (2001-08-29)
Protein maintains cross talk between cells that control hair growth
Genes, it turns out, are only as active as the signals that turn them on and off. Now scientists from Rockefeller University and the Howard Hughes Institute have identified the signaling molecule that ratchets up and clamps down the activity of key genes in dermal papilla, a type of skin cell whose unique collection of proteins ultimately instruct... view more...

Color Vision Drove Primates to Develop Red Skin and Hair, Study Finds
You might call it a tale of "monkey see, monkey do." Researchers at Ohio University have found that after primates evolved the ability to see red, they began to develop red and orange skin and hair. view more (2007-05-25)
