SAN FRANCISCO, Aug. 20 (Xinhua) -- Thomas Hwang, a retina expert at Oregon Health & Science University (OHSU) Casey Eye Institute, has a critical warning for spectators out to see a total solar eclipse on Monday.
"If you look directly at the eclipse Women's Nike Air Max 90 Ultra 2.0 Essential Triple White UK , it can burn your retina in mere seconds and can cause permanent damage," Hwang, an associate professor of ophthalmology in the OHSU School of Medicine, was quoted as saying in a web posting updated in recent days.
Oregon, in the U.S. Pacific Northwest, will be the first of 12 states in the United States to get a front row seat to observe the rare celestial event on Monday, August 21 - a total solar eclipse - where the moon completely covers the sun Nike Air Max 90 Mesh Triple Black UK Sale , and the sky goes dark in mid-daylight.
Scheduled to hit the U.S. West Coast around 10 a.m. Pacific time, there will be the most powerful "path of totality" going straight through Oregon, as it will last 2.5 minutes when the moon completely covers the sun.
The event is rare for two reasons: it will be the first total solar eclipse visible only in the United States since 1776 and the first total solar eclipse to cross the entire country in 99 years.
On his part, Hwang said the total solar eclipse can deliver a lot of energy to the center of vision, even when things seem kind of dark. He noted that most people normally would not look at the sun directly, but may not be as hesitant to look at a solar eclipse because it isn't as bright.
The damage to the eye is called solar retinopathy and it can give people a permanent blind spot; the longer the exposure, the hotter the retina gets and the more likely the damage.
"There's a simple solution: Wear the special solar eclipse safety viewing glasses to protect your eyes or use a pinhole projector Cheap Nike Air Max 90 Mesh Triple White UK ," he suggested, adding that "even with the special glasses, don't look at the eclipse for a long time. Sunglasses won't cut it either - they are not nearly good enough filters."

WELLINGTON Cheap Men's Air Max TN Shoes Black Red Sale , Oct. 13 (Xinhua) -- The diet of a small Malaysian spider could hold the key to curbing the spread of some of the world's worst human diseases, such as malaria, according to research by New Zealand, Singaporean, Chinese and Malaysian scientists.
The researchers discovered that the Malaysian jumping spider ( Paracyrba wanlessi) was the first and only predator known to specialize in preying on mosquitoes during all stages of the insect's life cycle, from larva and pupa through to the flying, blood-sucking adult Air Max 97 Shockproof Coral Light Pink Women's Sale UK , University of Canterbury scientists involved in the study said Monday.
"This is remarkable because a mosquito larva or pupa living in water is a very different animal from the active flying adult mosquito that pesters us in its search for blood," Dr Fiona Cross said in a statement.
"The spider doesn't need to learn how to identify and capture these different stages of the mosquito. We gave the spider the choice between lots of different prey and it consistently went for mosquitoes, regardless of whether these mosquitoes were adults or juveniles."
In Malaysia, Paracyrba wanlessi lived in fallen bamboo shoots where water entered the wood through small holes, making an ideal place to find juvenile mosquitoes in water as well as adult mosquitoes that returned to the water to lay their eggs.
"Finding predators that single out mosquitoes as preferred prey is especially interesting to people be.
