(PhysOrg.com) -- Geraldo Barbosa, professor of electrical engineering and computer science at Northwestern University has posed an interesting challenge. He wonders if the human eye and brain together are capable of actually seeing entangled images. This is not a philosophical question, as he has phrased the query as part of a practical experiment that someone with the proper lab could actually carry out.

Recent breakthroughs have enabled scientists from the Northwestern University's Center for Quantum Devices to build cameras that can see more than one optical waveband or "color" in the dark. The semiconducting material used in the cameras – called type-II superlattices – can be tuned to absorb a wide range of infrared wavelengths, and now, a number of distinct infrared bands at the same time.

Researchers at Northwestern University have developed a simpler way to generate single-chip terahertz radiation, a discovery that could soon allow for more rapid security screening, border protection, high sensitivity biological/chemical analysis, agricultural inspection, and astronomical applications.

Men may not go on a hormonal rollercoaster with their pregnant partners, but once the baby shows up, their bodies biologically transition into "daddy mode," suggests a new study finding that levels of testosterone, the "macho" sex hormone, drop in new fathers. "Men are, to a certain degree, hardwired to take care of their kids," study researcher Lee Gettler, of Northwestern University in Chicago, Illinois, told LiveScience. "This is important because traditional models of human evolution have portrayed women as the gatherers that take care of the kids and stay behind." [More]

Researchers at Northwestern University have created a new kind of cloaking material that can render objects invisible in the terahertz range.

(PhysOrg.com) -- Bartosz Grzybowski, a physical chemist at Northwestern University, and his team of colleagues offer evidence in a paper published in Science, that shows that what scientists have believed to be true about the causes behind the creation of static electricity, is wrong.

Google's tools don't easily translate into synthesized speech or Braille. Now the National Federation of the Blind has issued a federal complaint with the Justice Department, alleging that university use of Google Apps for Education amounts to discrimination.
