Stealth Paint to Make Airplane Invisible

Carbon Nanotube Coating Radar detection has always been the nightmare of military aircrafts. Once spotted in the radar zone, it is easy to destroy the aircraft in mid air by using anti-aircraft missiles. Defense personnel’s across the world are investing billions to develop better stealth equipped aircrafts that will easily escape from radar eyes.  The concept of stealth is applied on an aircraft by making changes in the aircraft design such that it deflects the radar beams instead of reflecting them. The aircraft design is such that there are no perpendicular sections in the body of the plane, so the…

Satellite Surgery Robot Developed to Repair Satellites

da Vinci console Artificial satellites placed in orbits are used for a variety of purposes like communication, GPS, military applications, TV broadcasting, and so on.  No matter how much time and money has been spent on building these hi-tech devices, satellites are basically just machines, and constant use can damage any machine. Every year NASA is spending millions of dollars just for the maintenance of these satellites, but they have not found a feasible way to repair a damaged one. Till present, there was only one option left for the researchers –completely blow–off the satellite!!They could not find any other…

Next Generation GPS Satellites

 Global Positioning System (GPS) is accessible to almost everyone by the introduction of smart phones. We can know our position and can locate any place by using satellites. Currently, the device has some limitations, as if GPS is not available inside houses, poor signal reception in remote places, and so on.  GPS systems currently can track up to 10 feet. However, this height is more than enough for consumer applications, the defense personnel’s are in need of a more accurate system.   Lockheed Martin, a high-tech company, is developing the next generation GPS satellites, with a tracking accuracy of almost 3…

World’s Smallest Sterling Engine Developed Using Nanotechnology

World’s Smallest Stirling Engine In this era of nanotechnology, from a transistor to a heat engine, everything is getting small. While reducing to micro size, we may think that the efficiency and performance of the device maybe compromised. However, researchers are trying their best to maintain the same ratings of a conventional device with its size being minimized.  Researchers from Stuttgart University and Max Planck Institute for Intelligent Systems have developed a micro particle that functions as a sterling engine (as small as 3 micrometers). A sterling engine is a heat engine in which gas expands and contracts there by…

Trillion Frames Per Second Camera – The Photon Catcher

Researchers at the Massachusetts Institute of Technology (MIT) have always had the legacy of doing things that were so called “impossible” by the rest of the world. Recently they came with an idea of a new imaging system that can capture photons at a rate of one trillion frames per second. Yes, you heard it right. Now we can capture the video of the fastest known particle in the universe, the photons. This virtual slow motion camera captures the video of photons traversing through space. This high-speed camera is more than enough to produce a slow motion video of light…

Study about the Earth’s Inner Core through X-ray Absorption Spectroscopy

X-ray Absorption Spectroscopy The information we know about the inside of the Earth (which includes the outer solid crust, the viscous upper and lower mantle, the liquid outer core, and the solid inner core), depends on the tests done by researchers through indirect methods. The way in which the different metals inside the Earth respond to intense heat and pressure are known by conducting different experiments of the samples in labs. Samples in the size of micro meters are collected and are heated with short intense laser pulses. Pressure is applied using diamond anvil cells. The substance remains in its…

Latest Discovery – World’s Lightest Material

Microlattice Material When it comes to light weight materials, the first thing that comes to our mind is Thermocol. Since its discovery in the year 1941, it has been used in many applications that are suitable for the common man like small life raft, disposable coffee cups, cushioning material in packaging, and so on. Since then, the weights of most light weight materials are compared to Thermocol, and have been given a special category called Ultra-light materials. A team of researchers from HRL Laboratories (Hughes Research Laboratories), in collaboration with Caltech and the University of California, developed a new material…

Lab Grown Blood Successfully Experimented on a Human

Luc Douay, a researcher at the Pierre and Marie Curie University in Paris was successful in creating artificial red blood cells in a lab. The researchers were also able to inject it into a human and the results were positive without any side-effects. A healthy volunteer was first selected for the program, and his hematopoietic stem cells were extracted from his bone marrow. Some of the basic growth factors that are required for the growth of a red blood cell were also mixed with this sample. Luc’s team labelled these cultured cells for tracing, and injected 10 billion of them…

See a Robot Workout!!

  Petman Boston Dynamics, an engineering company founded by Marc Raibert and his colleagues in the year 1992, have developed dynamic robots and its software for human simulation. Several innovations were made by them college life in Massachusetts Institute of Technology. They excelled in the field of robotics and developed robots that could run and epitomize all basic characteristics of animals. Lately, the researchers at the Boston Dynamics lab developed an anthropomorphic robot called Petman. It is a two-legged, upright robot designed to stand and walk like a man. The main aim of the machine is to test chemical warfare…

Flytrap Robots Can Hunt and Catch Bugs for Meals

Flytrap Robot Researchers at the University of Maine and the Seoul National University have developed two robots that can not only hunt small bugs, but can also digest them for filling their stomach. Both the robots depict the same principle of Venus Flytraps, who snap-shuts its mouth as soon as an insect sits on its sensitive hair.   The robot developed at Maine has muscles designed for capturing its prey. They are artificial in nature and are made of special gold type nanomaterials. The nanomaterials are designed to mimic the muscles that functions inside a flytrap’s mouth. The first report…
