Plants growing using plasma

Japanese’s Scientists from Kyushu University are working on a project that can helps the world to solve one of the most troublesome problems, the food dearth. The researches show that blasts of plasmas can decrease the crop time besides increase the yields.

The device generate 9.2-kilovolt and 0.2 amp of cold plasma containing a potent mix reactive oxygen and nitrogen molecules, photons, ions, and electrons.

Nanowire Production New Method could Revolutionize Photonics Applications

University Wollongong, Australia, researchers just published, in Nanoscale Journal, a new method nanowires production that could revolutionize the telecommunications applications.

The breakthrough is to add bismuth to the elements arsenic and gallium. The idea is that the bismuth resists the arsenic-gallium crystal junction, making a surface coat, which is an array of small droplets.

Smell Colors Mask

 

Synesthesia is a mix-up of the senses, when some sensation induce another.  Like when someone can sense the taste after seeing a picture of his favorite food, or when someone can see something just by hearing aleatory noise, or music.

Thinking about it Zachary decided to emulate the synesthesia from the color to smell. He used a color sensor that measure variations from red, green and blue and, from this measures, the system liberates a certain proportion from three…

New Software to Mind Reading

Scientists and engineers, from the BrainGate project, just published a paper, in the journal Science Translational Medicine, claiming they created a new decoder that senses mental electric signals with more efficiency. The main upgrade is on the software that compensate for the irregular nature of the neural signals.

Preliminary tests done using a typing interface, where a person with Amyotrophic Lateral Sclerosis could type with a good control of the interface. …

Android Robot

Android Robot

Each year more and more investments is done to develop android robots that can make simple tasks of our day. However that is not easy to be done as it seems. Drive a car, open a door or use a drill are actions that needs a lot of engineering.

The International Conference on Intelligent Robots and Systems in Humburg, Germany, was one of the biggest expo of this area and made a competition where the robots had to do eight simple tasks from a day of…

Sensors for Robotic Surgery

New pop-up sensor may help robotic surgery

Cirurgias feitas por robôs estão se tornando cada vez mais comuns, já que elas têm mostrado que os pacientes têm um tempo de hospitalização reduzido além de diminuir os riscos de erro e infecção, tornando a cirurgia mais segura. Uma grande desvantagem deste método de cirurgia, em comparação com cirurgias feita por pessoas, é que não existem sensores sensíveis e pequenos o suficiente para integrar o sistema que fará a operação.

Pensando nisso, os institutos John A.…

Information Trade Between Cars by Wi-Fi

The talk between cars is in test on the inaugurated Digital recently A9 Motorway Testbed in German. According with the minister of transport and infrastructure, Alexander Dobrindt, “This is the first demonstration of car-to-car communication via a high-speed cellular connection with near-5G performance”

This information trade between cars will allow that the cars know the location of others cars so they can control the speed according with the traffic.

Tool helps to Design 3D Printed Robot

The institute Disney Research and ETH Zurich developed a tool to help hobbyists to design a Robot from stretch and print it on a 3D printer. With this tool, the user can specify the shape, the size and the number of legs of a robotic creature. Beside this the system also ensures that the robot is capable of move has desired without falling.

According with Bernhard Thomaszewski, Disney Research scientist, “Our ambition is to make the design of compelling robotic…

A Robot Controlling a Switch

Residential automation are becoming more frequent on people life, and that’s what Tyler Bletsh did. He started working on a new office and the “smart” air conditioner, wasn´t “smart” enough to turn itself off during night.

Instead, there is a physical wall switch plate that is use to turn off the air conditioner manually, “like a barbarian”, according to Tyler. Avoiding being a barbarian, Bletsh make a robot using a servo that turn off the switch automatically and it…

Phototransistor Fast and Flexible

Developed by University of Wisconsin-Madison (UW-Madison) scientists, this flexible phototransistor based on single-crystalline silicon nanomembranes. They say that this is the fastest and most flexible one ever produced.

According to Zhenqiang Ma, one of the researchers, the used structure absorb more efficiently the light because it isn´t blocked by metal layers or other materials. A great advantage, according with the researchers, is that this flexibility allows…

The GPS Always Increase the Distance

Researchers of University of Salzburg (UoS), Salzburg Forschungsgesellchaft (SFG), and Delft University of Technology have done the math to prove that the distance measure made by GPS over a straight way will be, on average, longer range than the actual distance traveled. They also made a formula to calculate this error.

The measure errors have many causes, like the propagation delay, uncertainty in the GPS position, hardware error, and signal reflections.…

China is Planning to Build a Large Particle Collider

Chinese scientists just finished an initial project to build a large particle collider, where they pretend to collide protons inside a tunnel twice larger than the LHC (Large Hadrons Collider) that stays in Europe.

Named Super Proton-Proton Collider (SPPC), the Chinese Particles Collider would be an upgrade of the LHC and finished at 2040. Besides this project, the Chinese pretend to invest on International Linear Collider (ILC), a cooperative project from Europeans,…
