Eduard Driessen, MSc, and Dr Michiel de Dood's new paper in Applied Physics Letters identifies a new contender for the blackest material that ever existed. No word on whether it's any blacker than the last three Spinal-Tap-joke-inspiring none-more-black materials we've covered here since 2003.
Two researchers, Eduard Driessen, MSc, and Dr Michiel de Dood, have demonstrated that at a thickness of 4.5 nanometer niobiumnitride (NbN) is ultra-absorbent. They have recorded a light absorption of almost 100%, while the best light absorption to date was 50%. This research brings the ideal light detector a step closer.

Some snakes have evolved the ability to glide through the air. For example, paradise tree snakes in southeastern Asia can launch off from a branch and fly as far as 10 meters. Scientists have known that the snakes flatten their bodies to gain lift but new research reveals that they also undulate their bodies as […]
We humans are castaways on an ocean of uncertainty. Since the beginnings of history, our ancestors sought knowledge and understanding about their lives, their relationship with the cosmos, and perhaps take a peek into their future. In such effort—long before the answers of science—earthlings developed a rich variety of divination practices and systems. Many forms […]
NASA has funded a new research collaborative research effort between Harvard, the Smithsonian Institutions, and the University of Rochester to search for extraterrestrial intelligence (SETI). This is the first NASA grant for SETI in three decades and the first ever to search for signs of ET that aren’t radio transmissions. Instead, the scientists will look […]
Whether you’re working from home or working from the office, a few elements of the grind are universal. Emails never stop. Meetings go on way too long. And a bad monitor makes your day monumentally more difficult to tolerate. Staring at a screen that’s too small or isn’t bright or sharp enough can be enough […]
When you sit down on your couch to watch TV, the volume of options is truly staggering. However, a strange thing happens once you start cycling through page after page of Netflix suggestions and Amazon options. You invariably find yourself constantly considering the same set of giant Hollywood blockbuster films and major US television network […]
Back in the ancient times of the 1980s, if you wanted your thoughts quickly translated into text and didn’t want to spend all day transcribing all those meticulously archived notes yourself, you either needed to hire a secretary or a stenographer. Now, rather than spending thousands of dollars a year on an ultra-fast typist, technology […]
