Immune response against skin-dwelling viruses prevents cancer

Viruses get a bad rap as potential cancer-causers, but at least one class of viruses that commonly live on human skin – so-called “low-risk” human papillomaviruses – appear to play an unwitting role in protecting us against skin cancer according to a new study published in┬áNature. Patients who have immune systems that are suppressed from … Read more Immune response against skin-dwelling viruses prevents cancer

‘Flamenco dancing’ molecule could lead to better-protecting sunscreen

A molecule that protects plants from overexposure to harmful sunlight thanks to its flamenco-style twist could form the basis for a new longer-lasting sunscreen, chemists at the University of Warwick have found, in collaboration with colleagues in France and Spain. Research on the green molecule by the scientists has revealed that it absorbs ultraviolet light … Read more ‘Flamenco dancing’ molecule could lead to better-protecting sunscreen

Air pollution linked to hair loss, new research reveals

Research presented today at the 28th EADV Congress in Madrid shows, for the first time, that exposure to common air pollutants known as particulate matter (PM) is linked to hair loss in humans. The research was conducted by exposing cells from the human scalp at the base of hair follicles, known as human follicle dermal … Read more Air pollution linked to hair loss, new research reveals

Skin creams aren’t what we thought they were

Anyone who has gone through the stress and discomfort of raw, irritated skin knows the relief that comes with slathering on a creamy lotion. Topical creams generally contain a few standard ingredients, but manufacturers know little about how these components interact to influence the performance of the product. Now, researchers report the first direct glimpse … Read more Skin creams aren’t what we thought they were

Metal particles abraded from tattooing needles travel inside the body

Allergic reactions are common side effects of tattoos and pigments have been blamed for this. Now researchers prove, for the first time, that particles wear from the needle during the tattooing process and contain the allergens nickel and chromium and therefore could also induce allergies. The number of tattooed people has increased substantially in recent … Read more Metal particles abraded from tattooing needles travel inside the body

Functional hair follicles grown from stem cells

Scientists from Sanford Burnham Prebys have created natural-looking hair that grows through the skin using human induced pluripotent stem cells (iPSCs), a major scientific achievement that could revolutionize the hair growth industry. The findings were presented today at the annual meeting of the International Society for Stem Cell Research (ISSCR) and received a Merit Award. … Read more Functional hair follicles grown from stem cells
