An anonymous reader quotes a report from ScienceDaily: Humans and other mammals are limited to seeing a range of wavelengths of light called visible light, which includes the wavelengths of the rainbow. But infrared radiation, which has a longer wavelength, is all around us. People, animals and objects emit infrared light as they give off heat, and objects can also reflect infrared light. A multidisciplinary group of scientists led by Xue and Jin Bao at the University of Science and Technology of China as well as Gang Han at the University of Massachusetts Medical School, developed the nanotechnology to work with the eye’s existing structures.

In this study, the scientists made nanoparticles that can anchor tightly to photoreceptor cells and act as tiny infrared light transducers. When infrared light hits the retina, the nanoparticles capture the longer infrared wavelengths and emit shorter wavelengths within the visible light range. The nearby rod or cone then absorbs the shorter wavelength and sends a normal signal to the brain, as if visible light had hit the retina. “In our experiment, nanoparticles absorbed infrared light around 980 nm in wavelength and converted it into light peaked at 535 nm, which made the infrared light appear as the color green,” said one of the researchers. The researchers tested the nanoparticles in mice, which, like humans, cannot see infrared naturally. Mice that received the injections showed unconscious physical signs that they were detecting infrared light, such as their pupils constricting, while mice injected with only the buffer solution didn’t respond to infrared light. The study was published in the journal Cell.

The New York Times reported Thursday that an open letter will be published in the Times on Friday that asks Amazon to reconsider its decision to walk away from its plan to build a 25,000-employee campus in Long Island City, Queens. The company pulled the plug on the project, dubbed HQ2, following vocal and persistent opposition to the plan after it was announced three months ago. CNET reports: The letter was signed by the CEOs of Mastercard, Warby Parker, Goldman Sachs, Tishman Speyer and Jetblue, among others. The presidents of the Building & Construction Trades Council of Greater New York and state AFL-CIO, which were expecting thousands of construction jobs to come from the project, also signed, as did U.S. Reps. Hakeem Jeffries and Carolyn Maloney. “We know the public debate that followed the announcement of the Long Island City project was rough and not very welcoming,” the letter stated. “Opinions are strong in New York — sometimes strident. We consider it part of the New York charm! But when we commit to a project as important as this, we figure out how to get it done in a way that works for everyone.”

New York Gov. Andrew Cuomo has also had several conversations with Amazon, including CEO Jeff Bezos, about bringing back the project, the Times said. The letter and Cuomo’s behind-the-scenes efforts are part of the latest fallout since Amazon abandoned HQ2 in New York. The opposition has celebrated the exit as a victory for grassroots campaigns and a stand against lavish government incentives for new development plans. Amazon was slated to get about $3 billion in tax breaks for building the project. Supporters, who weren’t as vocal during the run-up to Amazon leaving, expressed shock and consternation about Amazon’s decision and worried that New York would appear unfriendly to new businesses. While the business community was broadly seen as in favor of the project, the letter shows how both the camps supporting and opposing HQ2 included unions and Democratic U.S. congress members.
