Beeld: Turkoois komt het dichtst in de buurt van de nieuwe kleur en kan je wel waarnemen zonder dat je ogen worden gelaserd. Het menselijk oog kan maar een beperkt aantal kleuren waarnemen; volgens de schattingen iets onder de 10 miljoen. Maar nu is het wetenschappers voor de eerste keer gelukt om buiten het normale kleurenspectrum te treden en een hele nieuwe wereld aan kleur te ontdekken.

Films of IR-sensitive material only tens of nanometers thick are tough to make. Military-grade infrared vision goggles use detectors made of mercury cadmium telluride, a semiconducting material that’s particularly sensitive to infrared radiation. Unfortunately, you need to keep detectors that use this material extremely cool—roughly at liquid nitrogen temperatures—for them to work.

There are only so many colors that the typical human eye can see; estimates put the number just below 10 million. But now, for the first time, scientists say they’ve broken out of that familiar spectrum and into a new world of color. In a paper published on Friday in Science Advances, researchers detail how they used a precise laser setup to stimulate the retinas of five participants, making them the first humans to see a color beyond our visual range: an impossibly saturated bluish green.

Rather than cycling, some of Mars' carbon took a one-way trip into rocks. Mars has not always been a seemingly lifeless red desert. We have evidence that billions of years ago it had a warm, habitable climate with liquid water in lakes and flowing rivers, which is somewhat confusing, given that Mars is much farther from the Sun than the Earth and that the Sun was much less bright back then.

“To measure biomass, you need to cut the tree down and weigh it, which is why we use indirect measuring systems,” says Klaus Scipal, manager of the Biomass mission. These indirect systems rely on a combination of field sampling—foresters roaming among the trees to measure their height and diameter—and remote sensing technologies like lidar scanners, which can be flown over the forests on airplanes or drones and used to measure treetop height along lines of flight.

Its performance isn't great, but its endurance is similar to standard lithium-ion. The Li-ion batteries that power everything from smartphones to electric cars are usually packed in rigid, sealed enclosures that prevent stresses from damaging their components and keep air from coming into contact with their flammable and toxic electrolytes.

Plant cells are surrounded by an intricately structured protective coat called the cell wall. It’s built of cellulose microfibrils intertwined with polysaccharides like hemicellulose or pectin. We have known what plant cells look like without their walls, and we know what they look like when the walls are…
