Michael Harper for redOrbit.com — Your Universe Online After all the research we´ve been doing for centuries, nature continues to surprise us from time to time, forcing us to reconsider long-held theories or showing us something totally new. Take, for instance, the reflective properties of silver fish, such as herring or sardines. It´s long been observed that these resplendent fish have the ability to deflect light, making it tricky for a predator to focus and snatch...

RED BANK, N.J., March 29, 2012 /PRNewswire/ -- Scientists at Natcore Technology Inc. (TSX-V: NXT; NTCXF.PK), using simple liquid bath processes, have created a black surface on a silicon wafer with an average reflectance in the visible and near-infrared region of the solar spectrum of 0.3%, making it the "blackest" silicon solar cell surface ever recorded. Compared with standard production cells now available, this represents a tenfold reduction in reflectance over that portion of the...

On the hottest day of the New York City summer in 2011, a white roof covering was measured at 42 degrees Fahrenheit cooler than the traditional black roof it was being compared to, according to a study including NASA scientists that details the first scientific results from the city's unprecedented effort to brighten rooftops and reduce its "urban heat island" effect. The dark, sunlight-absorbing surfaces of some New York City roofs reached 170 degrees Fahrenheit on July 22, 2011, a day...

A U.S. study suggests painted road markings such as lines separating lanes of traffic reflect headlights better in the direction the paint was applied. In other words the paint reflects more light if you are following the painting truck than if you are driving from the other direction, said the study co-author, North Carolina State University Professor Joe Hummer. Hummer, who conducted the research with Professor William Rasdorf and graduate student Guanghua Zhang, said the findings could...
