If you run a restaurant, or simply enjoy cooking at home, you are going to want to select the best ingredients available. Salt and other simple commodity ingredients probably don’t require much thought—one brand of table salt is likely as good as any other. But many ingredients, particularly fresh produce and meat, can vary wildly in quality and taste. Those can either end up elevating a meal, or ruining it. That’s why a team of scientists from Japan’s Prefectural Univers ...
The Moverio BT-30C will only cost you $499. These glasses may be smart, but the design isn’t so pretty. (Image credit: Epson)   My dream is to have smart glasses showing me AR info as I work on a project. But first, I suppose we need the basics.   Though smart glasses have been around for a while, they still haven’t caught on with the masses. Google hoped their Google Glass would be a hit, but it quickly fell out of favor. Epson is hoping to break into the consumer market ...
An implanted electrode picks up electrical signals, which are then translated to vocal movements and then speech sounds. Researchers use electrodes similar to this one to decode brain activity. (Photo from UCSF)   There are many diseases that can leas to loss of speaking, such as motor neurone disease, Parkinson’s, and multiple sclerosis. There are methods available that allow people to have some form of communication, but scientists at the University of California have developed a ...
On April 15th, 2019, the Notre Dame Cathedral in Paris, France, was set on fire, causing extensive damage to the historic gothic building. One of the main pieces of the cathedral, the spire, had collapsed during the inferno and the damage to its roof was severe. Most of the objects stored inside the building have been preserved, and the main structure of the building has been kept intact. Now the building can be restored with the help of technology left behind by the late Dr. Andrew Tallon who m ...
A new collaborative effort between Microsoft and the United States Department of Veterans Affairs (VA) was announced on April 30th. The aim of this collaboration is to provide a greater range of opportunities for education, recreation and therapy for veterans who suffer from mobility impairments. They hope to provide those services by adding an Xbox Adaptive Controller ─ which is an Xbox controller designed for people with mobility impairments ─ in certain VA rehabilitation centers in the U.S. & ...
Scientists are on the verge of discovering dark matter by using a very powerful detector filled with liquid xenon located a mile beneath Italy's Gran Sasso mountains. While searching for the dark matter particle, they were able to examine a rare event. The dark matter detector observed the decay of radioactive xenon-124.   Xenon-124 detector located underwater beneath Italy's Gran Sasso mountains. (Image Credit: Nature) Their findings, published in Nature on April 24, is a collaborati ...
This 3D printed heart was made using human fatty tissues (Image credit: Tel Aviv University)   3D printing can be used for various applications, like creating toys, clothing, and even food. But thanks to a new breakthrough it can even be used to create organs. Tel Aviv University researchers have successfully printed the world’s first 3D heart using a patient’s own cells and biological materials. They were able to produce an entire heart, complete with cells, blood vessels, ven ...
A $10,000 prototype took 21 hours to convert “HELLO” into DNA and back. Microsoft’s fully automated $10,000 prototype. (Image credit: Microsoft)   We have a looming data problem that companies like Microsoft are looking to solve. As more and more of our lives are digitized and file sizes balloon, we are rapidly approaching the limit of some of our most-used storage mediums.   Physical storage media such as hard disk drives (HDDs) will eventually reach a peak data de ...
Borophene (derived from boron) is stronger and more flexible than graphene, and has a high electronic conductance, making it an excellent material for sensors, batteries, and other applications. (Image credit: James L. Marshall via Wikipedia)   It wasn’t that long ago when graphene was turning heads in all areas of industry for its unusual properties- it’s incredibly strong, conducts heat and electricity with ease, and can be formed into many different structures (nanotubes, ba ...
Amazon’s Project Kuiper will deploy 3,236 satellites that will orbit the earth at various altitudes, and provide broadband service around the globe. (Image credit: Pixabay)   Back in September of last year, reports started surfacing about Amazon posting job offers (software engineer and Project manager) for what they termed a “New AWS (Amazon Web Service) service that will have a historic impact.” It slowly became known, that Amazon needed qualified people to develop clou ...
Introduction  This is the next instalment in my insulation tester review series, in a bid to find a more suitable tester for the type of work that I do. The previous testers reviewed are;   Keysight Insulation Multimeter Failure   Megger MIT420/2 Road Test   Chauvin Arnoux CA6526 Insulation Tester Review   Flir IM75 Insulation Tester Review   Extech MG302 Insulation Tester Review   Di-LOG DL9307 Insulation Tester Review   The RS Pro IIT1500 is marketed by ...
I'm designing a low power IoT in the Cloud framework for the Arduino MKR WIFI series. A firmware proof of concept that uses the low power option of this Arduino as much as possible, only to wake up to make a measurement and beam it to Amazon Web Services (AWS). The framework also reports the battery state. This allows the operator to go charge the battery before the defice runs out of juice. This blog measures the solution's power consumption over long time. It takes in account the time spe ...
  A team from Northwestern University has created a body sensor to help monitor babies in neonatal intensive care units (NiCU). The sensors are wireless, soft and flexible and have an advantage due to replacing other sensors that rely on wires to function. The sensors could be put to use in hospitals within the next two to three years.   Studies on premature babies were collected at Prentice Women's Hospital and the Ann & Robert H. Lurie Children's Hospital in Chicago. They foun ...
Introduction My car battery died recently, and I thought I’d try out an Energizer car jump-starter. This was a new product to me – I had not realized that such compact lithium ion jump starters were available! It reduces the need to find someone else’s car to do a jump-start.   In brief, it is a unit that looks like a USB power bank (it can be used as such) but with a rubber covered flap that has a connector to allow it to connect via a supplied adapter cable to a car bat ...
