Are you worried about how your bathroom cleaning supplies are damaging the environment and your own air? Use these recipes to create non-toxic, homemade bathroom cleaners instead. Never mix homemade cleaners with commercial cleaners, because when mixed, they can produce toxic gases. Use the same safety precautions as you would with store bought cleaners- keep them out of reach of children and pets, and out of your eyes and mouth. Always work in a well-ventilated area. Store your cleaning ingr...
Starting a business has to involve a desire to benefit someone else other than you. If all your reasons for starting a business are to benefit you, chances are good that you have missed the big picture. At least one reason you have to want to stat a business needs to be to help someone else. Either use proceeds from the business to help a charity of your choice or to solve a problem or provide a solution to a need for the target group that your business serves. Focus on one issue to start wit...
While the concepts of molecule interaction, zero force and energy states might be a little beyond an elementary school science fair's scope, the basic idea of water's capabilities and naturally prepared access to animals and insects that rely on it as a habitat is certainly worth the time. Learn how to duplicate this natural phenomenon in this free video clip series with our expert Scott Thompson as he demonstrates the occurrence of water skin or skin tension, and shows you and your children ...
Apple has implemented a new sensor on the rear camera of its fourth-generation iPad Pro, and it's pretty exciting. It's called the LiDAR Scanner, a scanning "light-detection and ranging" sensor, and you may very well be acquainted with it if you follow any driverless car news. Will we also get it on the upcoming iPhone 12 Pro?
With its 3D engine being responsible for approximately 60% of augmented and virtual reality experiences, Unity is continuing to place a premium on tools that not only keep developers working in its development environment but also make their workflows easier.
We're still weeks away from a probably HoloLens 2 release, but Microsoft's immersive computing team is still hard at work on other aspects of its "mixed reality" ecosystem.
While many of the latest content partnerships announced by Magic Leap appear to lean towards entertainment and gaming, a new partnership with medical technology provider Brainlab has Magic Leap getting down to more serious business.
From day one, my favorite thing about the Magic Leap One has been its portability. It's so well designed that it just screams to be taken out for a walk through the city. Alas, Magic Leap says the device is (currently) designed to be used indoors, preferably in settings containing few windows or black surfaces.
HTC is entering the augmented reality market through the back door by giving developers access to the stereo front-facing cameras on the Vive and Vive Pro VR headsets.
In the latest example of life imitating art, IBM has applied for a patent for a video censoring system that looks a lot like the "Arkangel" child monitoring system from the latest collection of modern sci-fi fables from Black Mirror on Netflix.
In what's becoming something of a regular occurrence, Magic Leap has yet another internal, unforced error on its hands. Thankfully, this time it's not about legal skirmishes or theft, but a rather unusual break from company protocol that has been quickly swept under the rug.
We already know that the connection between virtual and augmented reality is pretty tight, with tools like Unity making porting some apps between the two platforms fairly frictionless. But there are some things currently going in VR that just don't need to come to the world of AR.
There was a time when building a website required coding knowledge. Eventually, software came along that made the process easier, and then services like Squarespace made it dead simple for even a technical novice to design a website.
As demand for AR and VR developers continues to increase, particularly with the advent of Apple's ARKit platform, Unity has partnered with online learning company Udacity to help developers sharpen their skills for these jobs.
As the fish farming industry struggles to become more environmentally friendly, it just gained another problem. Fish food loaded with antibiotic-resistant genes.
As headlines focus on melting glaciers and rising water levels caused by global warming, climate change is quietly taking its toll on the nearly invisible occupants of this planet, the microbes.
Intel launched their Advanced Vehicle Lab in Silicon Valley this week, and the tech giant is now on the hunt for potential partners.
In a video released Tuesday, Microsoft arguably began to position the HoloLens and Windows Mixed Reality as the future of education. A smart tactic meant to coincide with their other education-related announcements made on the same day.
The ability of one microbe to adapt is giving it a whole new career as a sexually transmitted disease. Usually content with the back of the throat and nose of those who carry it, the dangerous pathogen Neisseria meningitidis has adapted to cause an illness that looks a lot like gonorrhea.
With products and solutions offered by the likes of Scope AR, Trimble, DAQRI, VIATechnik, and others, augmented reality is becoming a hot commodity for improving productivity while maintaining safety in the construction and manufacturing industries.
In the driverless race, technological advances can sometimes just add more tension to an already heated competition, if Waymo suing Uber over their allegedly stolen LiDAR technology is any indication. Now, Sony is offering a new camera sensor, one that should help self-driving cars "see" the road with much more accuracy than any other camera sensors available for vehicles currently.
With the British exit from the European Union looming, the UK is looking to the auto industry to help boost their economy and secure jobs through the upcoming years. Today, Business Secretary Greg Clark and Transport Minister John Hayes announced the government investment of $136.7 million (£109.7 million) across 38 different automobile projects, as a part of the Plan for Britain.
SSH local forwarding is a must for covering your tracks and getting out there to do your work. Also called SSH tunneling, this process will put one or more steps between your machine and the machine you're working on, for security and other purposes. It can be a bit daunting for newbies to get down, and that's where Punchabunch comes in.
HoloMaps, an application by Seattle-based Taqtile, is available for free on the Windows Store. Taqtile, whose Vice President of Product Management was Microsoft's former Director of Business Development, is one of the few partners currently in the Microsoft HoloLens Agency Readiness Program. This interactive 3D map they have created, powered by Bing, offers more than just a top-down view of the world on the HoloLens.
If you've ever made graphs and charts, you know it can be a struggle to represent a large amount of data. It's something that just doesn't work very well on a flat surface. In virtual and mixed reality, however, the data can exist all around you.
One of the major criticisms of virtual reality, and much modern technology in general, is the antisocial nature it creates. But vTime wants to overcome the isolating nature of VR headsets with a virtual hangout space for you and your friends.
Gender standards are entirely pervasive. We raise our sons to be masculine and our daughters to be feminine, which perpetuates the gender role formula when they grow up to be parents and raise their own children. Part of this whole equation is that boys are supposed to remain stoic and project an air of strength, and girls are expected to be amiable while being held to unrealistic standards of outward beauty.
Linux and Mac users have long enjoyed the use of multiple virtual desktops to free up clutter on their home screen and keep individual workflow environments separated, but Windows users have always been stuck with one solitary desktop.
As you already know, Hong Hong has been rocked in recent weeks by protests against their Beijing overlords. Promised free and fair elections, Beijing has reneged on this promise and is now telling Hong Kongians (that's what they're called, aren't they?) that they will only be able to vote on Beijing-selected candidates. All that is interesting from a political perspective, but from a technological perspective, the more intriguing story is how the protesters are communicating. Faced with their...
There are plenty of tank robots out there, but how many of them can recognize 3D objects and map their environment? Tanky, the tracked mobile robot, can do all that and more while rolling around on his bicycle chain treads. Created as a Master's thesis project, Tanky is made almost entirely of parts you can find at your local hardware store. It was built in two "layers" with the motors, electronics, and batteries on bottom and the processing unit, a laptop, on top. The motors came from cordle...
