We’ve seen a few learning systems that help students to learn at their own pace by having them follow lights to form chords on a guitar or nail songs on a piano keyboard. The latest from Yamaha to do so is the EZ-300, which comes with songs built-in.Co… Continue reading Yamaha makes learning piano EZ with follow-the-light keyboard
Real sunlight is a beautiful thing, but due to the vagaries of Earth’s orbit and local weather systems, it’s not available all the time. [Matt] decided this wasn’t good enough, and set about building a rig to replicate the sun’s rays as closely as possible.
The great distance between the …read more

Earth isn’t the only place that’s heating up of late – the universe seems to be too. Astronomers at Ohio State University have taken the mean temperature of cosmic gas at different distances and ages, and found that it’s roughly 10 times hotter today t… Continue reading Mean temperature of the universe is rising over billions of years

An Alphabet X innovation lab project has been working on a high-speed wireless optical communications network that uses beams of light instead of cables or radio waves, and folks in Kenya will be the first to benefit from the fruits of these labors.Con… Continue reading Alphabet project uses light beams to bring broadband to remote regions
Windows are great for letting in light, but in summer months that comes with an unwanted side order of heat, causing many people to run the air conditioning non-stop. Now, researchers have developed windows that can change color automatically when heat… Continue reading Smart windows darken and become solar cells when heated
Physicists in Germany have measured the shortest timespan ever recorded. The team measured the time it takes for a photon of light to travel the length of a hydrogen molecule, and found it to occur in just trillionths of a billionth of a second.Continu… Continue reading Shortest event ever measured lasts mere sextillionths of a second
No, no, at first we thought it was a Pokemon too, but Placemon monitors your place, your home, your domicile. Instead of a purpose-built device, like a CO detector or a burglar alarm, this is a generalized monitor that streams data to a central processor where machine learning …read more
One method of 3D printing involves selectively exposing liquid resin to ultraviolet (UV) light, causing that resin to harden into a solid. Now, scientists have developed a new resin that works with safer, more energy-efficient visible light.Continue Re… Continue reading Practical new 3D printing resin optimized for visible light
Three years ago, scientists from the University of Arizona reported that exposure to green light appeared to reduce neuropathic pain in rats. Now, the researchers believe that such light could also be used to treat migraine headaches in humans.Continue… Continue reading Daily doses of green light may minimize migraines
