But I don't want to eat a cow! Do you feel bad about your place at the top of the food chain? Does the thought of even eating an animal cracker make you sad? Take heart! Meat-eater-ologists have found a solution that gives us meat without killing an animal. Loosen up your belt and get ready for meat grown in a lab! That's right - quicker than you can say "yuck, you can't make me eat it", scientists can grow up to 80,000 quarter pounder patties from a single tissue sample from a cow. The meat looks like meat, feels like meat, and tastes like meat because, well, it is meat. Under a microscope, you can't tell the difference between animal meat and cultured meat. The
Scientist 3D printed a Star Trek USS Voyager spaceship that is smaller than the width of a human hair.
Scientists at Leiden University in the Netherlands have created a 3D-printed version of Star Trek's USS Voyager spaceship that measures a ultra-tiny 15 um (micrometers) long. By comparison, the width of a human hair is 50 um. The USS Voyager spaceship is so tiny, it can only be viewed through a microscope! Microswimmers Scientists create microscopic models so they can study "microswimmers". Microswimmers are important because they will one day lead to tiny swimming robots that can be turned loose in the human body to repair tiny injuries or deliver drugs to a precise location inside the body. Because they are so tiny, microswimmers face a variety of challenges that scientists must solve. For instance, their small size and shape means they are impacted by the fluid's viscosity
Solar power scientists are now using molten salt to store the sun’s energy. Here’s the science of how it works.
In June 2019, China’s Dunhuang molten salt solar thermal power plant hit 100MW, its maximum power levels. The plant will provide 390 million kWh of clean power each year and reduce carbon dioxide emissions by more than 3500 tons. And it can run 24-hours a day, even when the sun does not shine. It does this by storing energy in a molten salt solution for later use. More and more solar power plants are turning to molten salt to solve solar energy’s number one problem – where to get energy at nighttime or when the sun is behind clouds. Solar energy could be stored in normal batteries but batteries are expensive and not very good for the environment. Instead, the energy can be stored in molten
Hold on tight because this video shows a high-speed test at the Holloman Air Force Base in New Mexico that makes us think the Air Force should be designing roller coasters. The sled in this video reaches a dazzling speed of 6,599 miles/hour. That's Mach 8.6 for the science nerds. https://youtu.be/RQwDicADKIU The Holloman High Speed Test Track (HHSTT) is a United States Department of Defense/Air Force aerospace ground test facility located at Holloman Air Force Base in south-central New Mexico. According to the Air Force: "The Holloman High-Speed Test Track is a 10-mile long, precision-aligned track that provides scientists and engineers a platform from which to conduct their various missions. Tests on the track provide valid data on problems which cannot be solved by other ground test means." Sources:
First we had giant rail guns, then killer robots, and now creepy deadly swarms of automated drones – all for the purpose of protecting the United States and giving little kids nightmares. What is a Perdix drone? The Perdix drone, or more accurately, micro-drone, was designed by the geniuses at MIT in 2013. Each drone has a wingspan of only 12 inches with tiny 2 ½ inch propellers. They are fast, nimble, and can fly for about 30 minutes on a single charge. What they do Perdix drones fly in swarms – large groups of tiny drones flying close together. The drones communicate with other drones in the swarm. This lets them act like a collective organism, similar to a swarm of bees or flock of birds. The drones
Computer programming is a foundational skill that lets future generations do things with information we can hardly dream of
Fun Ways To Get Kids Interested In Learning How To Code We live in a world filled with information. This has always been true but today, the tools exist for all of us to see and use that information. Coding and computer programming are the foundational skills that will let future generations do things with the information around us that we can hardly dream of. We now must start teaching those skills to our children. Fringe Benefits At their roots, programming and coding are about two things: working with information and solving problems. It does not take much thought to realize that these two concepts are applicable in a virtually endless array of different applications. Children who learn the fundamentals of coding will be able to start applying
Boston Dynamics continues to blow us away with its amazingly lifelike robots and such is the case with the newest version of the Atlas robot. Atlas is a humanoid robot made by Boston Dynamics (the makers of the ever-popular BigDog military robot). Atlas can walk on two legs and use its “arms” to lift, carry, and climb (and maybe one day, fight back against robot bullies). Atlas is even sophisticated enough to adjust and navigate through tight, cluttered places. Atlas features 28 hydraulically-actuated degrees of freedom and a sensor head with cameras and a laser range finer (LIDAR). It stands 5 feet 9 inches and weighs 180 pounds (compared to its 330-pound predecessor, that’s lightweight). There are several Atlas robots being manufactured. Check out the video below
Regular visitors to Reeko’s Mad Scientist Lab know Reeko loves robots. In fact, he’s pretty much fanatical about Boston Robotics’ four-legged dog robots (fanatical enough that some of us are beginning to worry). Check out the amazing video below which features a public service announcement call-to-action to stop the abuse of robot dogs. Join the movement! #stoprobotdogabuse Funny video–stop robot dog abuse Weighing in at 160 pounds, these wonderful robot dogs are able to run, climb stairs, jog next to its owner, and even recover its balance after being kicked! The robotic dog uses cameras and sensors to help it navigate over rough, uneven terrain. It can recognize humans and other robotic dogs and we think, but are not totally sure, that it can even pee on
Like marriage, tattoos often seem like a good idea at the time. But teens often fail to realize that the cool barbed wire tattoo is going to be little more than a picket fence when they get old. Now you can get a temporary tattoo that eventually wears off (hopefully by the time you have to go out and get a job) and serves a useful purpose while you wait for it to disappear. Researchers at the University of California San Diego have designed a sensor which can be imprinted onto temporary tattoo paper and when affixed to a person’s arm, can not only monitor a person’s progress during exercise, but generates electricity from the person’s sweat. The sensors works by detecting lactate, which is naturally
When the robot invasion starts (when robots take over the world and enslave the human race), proper robot self-defense is going to be difficult – especially now that we find out we can’t throw rocks, furniture, or small children at them while we flee. You see, this amazing robot can catch anything you throw at it. The armature of this robotic arm has four fingers and a three-jointed hand that can react at a blazing 5/100ths of a second. The software on this EPFL-developed robot allows it to be “taught” how to catch by a human. A human moves the robot’s arm around manually until it “learns” how to catch the object. Then the robot uses its camera-based tracking system, which tracks trajectory, speed, and rotation of
