People whose vision is badly damaged by over-exposure to bright light may be able to restore their sight, scientists say. Australian researchers at The Vision Centre are working on a non-invasive method that involves shining near-infrared light (NIR) into damaged eyes to invoke a natural process which encourages the eye to heal itself. "The use of NIR in healing eyes stressed by bright light has now been established, in animals," says Dr Krisztina Valter, a Chief Investigator in the ARC...

Government funded researchers have found that they can get women to cut back on sunbathing by getting them to use tanning lotion instead. According to the Centers for Disease Control and Prevention (CDC), most of the skin cancers diagnosed every year in the U.S. are sun-related.  Melanoma, which is the most deadly kind, kills about 8,700 people every year. U.S. researchers tested whether offering sunbathing women free samples of tanning lotion and sunscreen could heighten awareness of...

About one in ten U.S. adolescents uses sunless tanning products, and an intervention promoting these products as an alternative to regular tanning may reduce sunbathing and sunburns among adult women, according to two reports in the September issue of Archives of Dermatology, one of the JAMA/Archives journals. Ultraviolet radiation exposure was recently upgraded to the highest cancer risk category and is the most common avoidable cause of skin cancer, according to background information in...

NAPA, Calif., Sept. 13 /PRNewswire/ -- Clean Power Research announces the publication of a novel approach to quantifying power output variability in "fleets" of photovoltaic (PV) systems. The paper, published in Solar Energy - the official journal of the International Solar Energy Society® - shows that the relative power output variability for a fleet of PV systems can be quantified by specifying the number of PV systems and a quantity referred to as the dispersion factor....

New technique may help restorers identify decades-old pigments A team of McGill chemists have discovered that a technique known as photoacoustic infrared spectroscopy could be used to identify the composition of pigments used in art work that is decades or even centuries old. Pigments give artist's materials color, and they emit sounds when light is shone on them. "The chemical composition of pigments is important to know, because it enables museums and restorers to know how the paints will...

According to researchers at Edinburgh University, people may be disappointed when trying to get tan by soaking up sunrays this summer. The researchers said that different parts of the body go brown at different speeds, so achieving that idealized image of beauty is not going to happen. The findings explain why certain people find it difficult to get an even, consistent tan.  The main problem is people's bottoms, which take a lot longer to go brown than other parts of their anatomy....

A consistent all-over tan may be impossible to achieve because some body areas are much more resistant to tanning than others, a study has found. Researchers - funded by the Medical Research Council (MRC) - at the University of Edinburgh say the results explain why some holidaymakers find it so hard to achieve an even tan all over their body. The findings, published in the journal Experimental Dermatology, show that the buttock is much more resistant to sunshine but surprisingly when it does...

In a new Spanish study, researchers are warning that taking shade under a beach umbrella may offer far less protection from harmful ultraviolet radiation from the sun than you might expect. Beach umbrellas let as much as 34 percent of ultraviolet radiation penetrate through to the ground, the researchers, from the University of Valencia, found. Ultraviolet radiation is known to cause skin cancer and cataracts. Umbrellas catch almost all of the direct light rays but not the diffused...

The above image looks at the month of March for the three cycles known as Normal Phase, El-Nino, and La-Nina. The data was recorded for the city of Honolulu Hawaii, during the month of March. Remember this is just data for one month during these cycles. Normal: During this cycle incoming solar activity was upwards to 48% efficient for the month, producing less than 50% of the month which is due to the large amount of daily cloud cover that is seen on the island during the early morning and...

The above image looks at the month of March for the three cycles known as Normal Phase, El-Nino, and La-Nina. The data was recorded for the city of Austin Texas. Remember this is just data for one month during these cycles. Normal: During this cycle incoming solar activity was upwards to 60% efficient for the month, producing enough solar energy that only 40% of the month would have not had strong incoming radiation. EL-Nino: This phase provided the area with an extended number of...

Sunglasses are protective eyewear designed to shield the eyes from damaging or discomforting sunlight and high-energy light. They can also work as a visual aid. The ultraviolet radiation from the sun can cause several serious eye problems and many healthcare professionals recommend eye protection. However, since the 1940s sunglasses have been associated with celebrities more so than eye protection. James Ayscough experimented with tinted lenses in the mid-18th century although they were...
