An all over tan is fashionable and large numbers of people, especially young women, achieve this by using sunbeds. Professor Antony Young, of King’s College London, has reviewed the evidence that links sunbed use to malignant melanoma; a skin cancer that is fatal if not detected and treated early. Malignant melanoma is a cancer of the skin’s cells that are responsible for tanning (melanocytes). Unlike most cancers, that tend to occur in late middle age, malignant melanoma can appear in younger people. There are about 6000 new cases of malignant melanoma in the UK each year and it is the 3rd most common cancer in women under 35. New data published earlier this week shows that malignant melanoma in the UK has increased by 24% in the period 1995-2000.
The tanning properties of sunbeds come from their UVB and UVA radiation, both of which are found in the sun’s ultraviolet rays. This radiation is known to damage the skin’s genetic information and its immunity, and it is these effects that result in skin cancer. Tanning is increasingly recognized as the skin’s SOS response to damage by ultraviolet radiation (UVR). It is often argued that a tan is protective but in reality a suntan is equivalent to a sunscreen with a very low sun protection factor (SPF) and its acquisition is associated with an accumulation of DNA damage.
Professor Young’s review, in Pigment Cell Research, shows that there is increasingly compelling evidence for a link between sunbed use and malignant melanoma. This link is not surprising because the sun’s UVR is widely recognized as the primary cause of malignant melanoma. The continuing and widespread use of sunbeds is likely to result in increased numbers of people with malignant melanoma. There is a good case, as is done in some countries, for restricting sunbed use to those of 18 years of age and above. It is also worth noting that the regular use of sunbeds will markedly accelerate skin ageing.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
