Since the German chemist Martin Heinrich Klaproth identified uranium in 1789, atomic number 92 has become one of the most troubling substances on the planet. It’s naturally radioactive, but its isotope uranium-235 also happens to be fissile, as Nazi nuclear chemists learned in 1938, when they did the impossible and split a uranium nucleus in two.
Like us, mice can’t see in the infrared. Well, most mice can’t. There are a few rodents in a laboratory that can see infrared light after being enhanced with special nanoparticles. The team thinks a similar procedure could work on humans, giving you night vision without any bulky goggles. You just need to be willing to get nanoparticles injected into your eye
According to SmithsonianMag.com –
The team filmed rats, dogs, goats, cows and elephants urinating and gathered footage from YouTube of others relieving themselves. Combining this with data on mass, bladder pressure and urethra size, they were able to create a mathematical model of urinary systems to show why mammals take the same time to empty their bladder, despite the difference in bladder size.
China’s Chang’e 4 spacecraft achieved the milestone at 10:26 a.m. on Jan. 3 in Beijing (6:26 p.m. PT on Jan. 2), with the country’s space agency landing its lunar probe in Von Karman crater on the moon’s mysterious far side.
. . . nothing beats a clear image, says INRS professor and ultrafast imaging specialist Jinyang Liang. He and his colleagues, led by Caltech’s Lihong Wang, have developed what they call T-CUP: the world’s fastest camera, capable of capturing 10 trillion (1013) frames per second (Fig. 1). This new camera literally makes it possible to freeze time to see phenomena—and even light—in extremely slow motion.
Watch a short video from PBS that explains a little of the basics of photovoltaic cells and silicon. The full 53 minute documentary can also be watched on the page.
Silicon is a metalloid: an element with properties not quite like a metal, nor exactly like a non-metal. If you have a cell phone in your pocket or dirt on your shoes, you’re carrying silicon. Learn more about this ever-present element.
Famed astronomer Galileo Galilei discovered the first four moons of Jupiter way back in the early 1600s. More than 400 years later, astronomers are still finding moons orbiting the solar system’s largest planet. We’re not just talking about one or two stragglers, either. Astronomers from the Carnegie Institution for Science have spotted 12 new moons orbiting Jupiter, bringing the total to 79.
Miniscule robotic drones might be the future, but they’ve been tricky to get off the ground. Until now, any wing-flapping insect robot had to have a power source, making it too heavy to lift off with its tiny wings. Now, however, researchers at the University of Washington have found a way to transmit power to a flying robotic insect (lovingly dubbed RoboFly) via laser, obviating the need for a separate power supply.
NASA has confirmed its upcoming Mars 2020 rover will carry a small robotic passenger. The agency has been working on a helicopter drone for use on Mars, and it now plans to include this vehicle with the 2020 rover. The still-unnamed Mars helicopter will be the first heavier-than-air craft to fly on another planet. In doing so, it will help the 2020 rover mission cover more ground and learn more about Mars.
