New source of multipotent adult stem cells discovered in human hair follicles
Researchers at the University of Pennsylvania School of Medicine have isolated a new source of adult stem cells that appear to have the potential to differentiate into several cell types. view more (2006-07-13)
Ancestry attracts, but love is blind
People preferentially marry those with similar ancestry, but their decisions are not necessarily based on hair, eye or skin colour. view more (2009-11-20)
New discovery leaves blood-doping athletes scratching their heads
A stunning discovery by German scientists may make blood doping and the treatment of severe anemia as easy as washing your hair. view more (2007-09-21)
Some children are born with 'temporary deafness' and do not require cochlear implant
Clinical research conducted in the Department of Communication Disorders at the University of Haifa revealed that some children who are born deaf "recover" from their deafness and do not require surgical intervention. view more (2007-05-17)
Men are opting to remove spider veins over replacing hair
The American Academy of Cosmetic Surgery (AACS) is pleased to announce the results of its 2007 Procedural Data. This information is collected by polling the Academy's U.S.-based members. view more (2008-03-17)
A screening strategy using zebrafish targets genes that protect against hearing loss
A small striped fish is helping scientists understand what makes people susceptible to a common form of hearing loss, although, in this case, it's not the fish's ears that are of interest. view more (2008-03-03)
Sulphur in just one hair could blow a terrorist's alibi
A group of researchers from the LGC Chemical Metrology Laboratory in the United Kingdom and the University of Oviedo, Spain, have come up with a method to detect how the proportions of isotopes in a chemical element (atoms with an equal number of protons and electrons but different numbers of neutrons) vary throughout the length of a single hair. view more (2009-05-28)
Tendency to hair loss inherited from the mother
The male sex hormones really do seem to play a decisive role in causing hair loss in men. This has been confirmed by scientists from the universities of Bonn and Düsseldorf. Their studies show that specific changes in the genetic 'construction manual' of the androgen receptor may result in premature balding. Androgens are hormones which play... view more... (2005-05-20)
Action needed to stop "disease mongering"
A lot of money can be made from telling healthy people they’re sick despite clear conflicts of interest. Pharmaceutical companies sponsor disease definitions and promote them to prescribers and consumers. In this week’s BMJ researchers give examples of “disease mongering” and suggest how to prevent the growth of this... view more... (2002-04-10)
Researchers discover baldness gene: 1 in 7 men at risk
Researchers at McGill University, King's College London and GlaxoSmithKline Inc. have identified two genetic variants in caucasians that together produce an astounding sevenfold increase the risk of male pattern baldness. view more (2008-10-13)
Bedsores and bald hides: Novel roles revealed for a 'scaffolding' protein
A protein long thought to provide only mechanical support for keeping cells and tissues from literally falling apart turns out to have much wider utility. view more (2006-05-18)
New synthetic self-assembling macromolecules mimic nature
We take "self-assembly" for granted when it is carried out by the biopolymers which are our hair, teeth, or skin. But when scientists devise new ways for molecules to self assemble into new materials, it is an important achievement. view more (2007-03-20)
Ancient DNA reveals that some Neanderthals were redheads
Ancient DNA retrieved from the bones of two Neanderthals suggests that at least some of them had red hair and pale skin, scientists report this week in the journal Science. view more (2007-10-26)
Researchers find lack of key molecule leads to deafness
Researchers have identified tiny molecules that may lead to big breakthroughs in the treatment of hearing loss and deafness. view more (2009-04-17)
Using hair to manage HIV/AIDS and predict treatment success
UCSF researchers have found that examining levels of antiretroviral drugs in hair samples taken from HIV patients on therapy strongly predicts treatment success. view more (2009-03-04)
Expression of 'Blimp1' gene leads to the discovery of cells responsible for skin's sebaceous gland
Mice may not get zits, but they do have oily skin. This week, new research on mice from Rockefeller University shows how the cells responsible for oil production develop, and uncovers clues about how stem cells renew and differentiate. view more (2006-08-11)
The colour of your hair may leave you open to stereotypes and prejudice
Hair colour has been associated with stereotypes of females in western society and it appears that the stereotype of 'dumb blonde' is still alive and well. There is also some evidence that men rather than women have constructed the dumb blonde stereotype. view more (1999-03-26)
Scientists uncover Inca children's countdown to sacrifice
Hair samples from naturally preserved child mummies discovered at the world's highest archaeological site in the Andes have provided a startling insight into the lives of the children chosen for sacrifice. view more (2007-10-02)
Scaling the Wall of Deafness
Despite modern medicine, one in 1,000 American babies are born deaf. The numbers increase markedly with age, with more than 50% of seniors in the United States experiencing some form of hearing loss. view more (2009-04-15)
Toxic milk
In the August 1 issue of G&D, Dr. Ronald Evans (Salk Institute) and colleagues report on their discovery that mutations in the mouse gene encoding PPARγ adversely affect lactation milk quality, and have serious health consequences for nursing pups. view more (2007-07-24)
