‘Superhero’ 3D printed hands help kids dream in Argentina

In this June 12, 2017 photo, Kaori Misue breaks into a smile in Buenos Aires, Argentina. Misue has a brand new prosthetic hand thanks to the genius of 21-year-old inventor Gino Tubaro and his 3D printer. Today, more than 500 people, mostly children, have received similar prostheses and 4,500 more remain on a waiting list. (AP Photo/Natacha Pisarenko) Being born without fingers can be tough for any child. Getting new ones—especially red and blue superhero themed digits—has made 8-year-old Kaori…

New method for 3-D through-wall imaging that utilizes drones and WiFi

Researchers at UC Santa Barbara professor Yasamin Mostofi’s lab have given the first demonstration of three-dimensional imaging of objects through walls using ordinary wireless signal. The technique, which involves two drones working in tandem, could have a variety of applications, such as emergency search-and-rescue, archaeological discovery and structural monitoring. “Our proposed approach has enabled unmanned aerial vehicles to image details through walls in 3D with only WiFi signals,” said Mostofi, a professor of electrical and computer engineering at UCSB. “This…

Small Farm Robots » Curious Cat Science and Engineering Blog

Small Farm Robots Posted on June 17, 2017  Comments (0) The IdaBot was created by researchers at Northwest Nazarene University (Idaho, USA). Using robots in farming is limited today but the future could see a huge growth in that use. Benefits of introducing more robots to farming include reducing the use of pesticides and chemicals to control weeds. Reducing labor costs is also a potential benefit but at current market prices (due to high costs of robotics and available cheap…

Compound shows potential for high-temperature superconductivity — ScienceDaily

A team of researchers at the U.S. Department of Energy’s (DOE) Argonne National Laboratory has identified a nickel oxide compound as an unconventional but promising candidate material for high-temperature superconductivity. The team successfully synthesized single crystals of a metallic trilayer nickelate compound, a feat the researchers believe to be a first. “It’s poised for superconductivity in a way not found in other nickel oxides. We’re very hopeful that all we have to do now is find the right electron concentration.”…

Is Bitcoin a Viable Currency?

The recent rise in the value of Bitcoin has the captured the world’s attention with its recent meteoric price bubble. The value of Bitcoin has grown over 200% in 2017 alone. If you are considering jumping into the mania and purchasing a Bitcoin, here are five good reasons why you may want to sit on the sidelines a little longer. The Pro’s of Bitcoin Bitcoin does have some truly unique characteristics. One of the most attractive points is the fact…

Combatting weeds with lasers

Tim Wigbels (left) and Dr. Julio Pastrana (right) with their weed recognition software which is detecting a plant and how the laser system is shooting and damage its foliage. Credit: Volker Lannert/Uni Bonn A robot automatically identifies weeds in a field and combats them with a short laser pulse. Sustainable agriculture, which avoids the use of herbicides as far as possible, could benefit from this smart idea. Dr. Julio Pastrana and Tim Wigbels from the Institute of Geodesy and Geoinformation…

Researchers debut battery-less pacemaker

The internal components of a battery-less pacemaker introduced this week by Rice University and the Texas Heart Institute. The pacemaker can be inserted into the heart and powered by a battery pack outside the body, eliminating the need for wire leads and surgeries to occasionally replace the battery. Credit: Rice Integrated Systems and Circuits/Rice University A wireless, battery-less pacemaker that can be implanted directly into a patient’s heart is being introduced by researchers from Rice University and their colleagues at…

Researchers use AI to dramatically increase image clarity under severe conditions

NEC Corporation and Tokyo Institute of Technology (Tokyo Tech) today announced their joint development of a multi-modal image fusion technology that dramatically improves the clarity of images by using artificial intelligence (AI) to automatically combine visible images taken by standard cameras with non-visible images taken by specialized devices, such as thermal or terahertz cameras. Credit: Obtained permission to use the severe environment simulator in the ImPACT Tough Robotics Challenge program. In recent years, technological advancements and cost reductions for specialized…

Cambria Corn Mill Dust Explosion Kills Three

Last Wednesday, May 31, everything seemed normal at the Didion corn mill in the small village of Cambria, Wisconsin.  Like most factories of its type, the mill operated 24 hours a day, and late that night only sixteen workers remained as the machinery processed corn into ethanol and other products.  Shortly after 11 P. M., a tremendous explosion sent flames high into the air, knocked out power, and destroyed most of the processing division of the plant.  Three workers were…

New mechanism behind Parkinson’s disease revealed — ScienceDaily

OIST researchers have identified the precise toxic mechanism at work during an overabundance of the protein alpha-synuclein in neurons — the protein is a key causative agent in the development of Parkinson’s disease. Parkinson’s disease is a debilitating neurological illness that affects approximately 10 million people worldwide. It is marked by a progressive decline in physical function, the most iconic being uncontrollable tremors, and involves the malfunction and eventual death of nerve cells located in the brain. There is no…
