HemoGlobe device can identify women with anemia

Could a low-cost screening device connected to a cell phone save thousands of women and children from anemia-related deaths and disabilities? That's the goal of Johns Hopkins biomedical engineering undergraduates who've developed a noninvasive way to identify women with this dangerous blood disorder in developing nations. The device, HemoGlobe, is designed to convert the existing cell phones of health workers into a "prick-free" system for detecting and reporting anemia at the community level.

Sunbed users at a 20% increased relative risk of skin cancer

Of 63,942 new cases of cutaneous melanoma (a form of skin cancer) diagnosed each year in Europe an estimated 3,438 (5.4%) are related to sunbed use. Sunbed users are at a 20% increased relative risk of skin cancer compared with those who have never used a sunbed. This risk doubles if they start before the age of 35 and experts warn that “tougher actions” are needed to reduce this risk.

Novel tiny spectrometer can detect food quality

Whether fruit, meat or cheese - the quality of food is not always as consumers would like it to be. But, in future, a spectrometer will allow them to gage the quality of food before they buy it. No bigger than a sugar cube, the device is inexpensive to manufacture and could one day even be installed in smartphones.

Hand rejuvenation therapy effective for reducing damage

We greet each other with our hands, whether with a handshake or a wave. We absentmindedly show off our hands when we reach for something, point somewhere, or just scratch our heads. Our hands are almost always visible and unprotected from the elements.

Chemists build light-controlled neural inhibitor

The notion of a pain switch is an alluring idea, but is it realistic? Well, chemists at LMU Munich, in collaboration with colleagues in Berkeley and Bordeaux, have now shown in laboratory experiments that it is possible to inhibit the activity of pain-sensitive neurons using an agent that acts as a photosensitive switch. For the LMU researchers, the method primarily represents a valuable tool for probing the neurobiology of pain.

New combination laser therapy effective in treating melasma

On the surface, it would seem as though the skin condition melasma (commonly referred to as the "mask of pregnancy") and tattoos would have little in common. However, they both affect a person's skin, can be quite difficult to treat or remove and, now, dermatologists are discovering new laser therapies which enhance treatment for both conditions.
