Playtronica’s MIDI device turns vegetables into musical instruments

Creative technology studio playtronica has found a way of making music with pretty much anything including vegetables. their electronic devices transform touch into midi notes making anything into a midi controller including one that turns the human body into a keyboard. how it works is by effectively creating a circuit between the device and human body or the fruit. it’s then connected to a computer so when you touch the instrument the circuit is closed, and a specified sound is played. the tools are designed to work with organic materials and mostly anything that has water inside.

Earable computing: A new research area in the making

CSL’s Systems and Networking Research Group (SyNRG) is defining a new sub-area of mobile technology that they call “earable computing.” The team believes that earphones will be the next significant milestone in wearable devices, and that new hardware, software, and apps will all run on this platform.

“The leap from today’s earphones to ‘earables’ would mimic the transformation that we had seen from basic phones to smartphones,” said Romit Roy Choudhury, professor in electrical and (ECE). “Today’s smartphones are hardly a calling device anymore, much like how tomorrow’s earables will hardly be a smartphone accessory.”

Instead, the group believes tomorrow’s earphones will continuously sense , run acoustic augmented reality, have Alexa and Siri whisper just-in-time information, track user motion and health, and offer seamless security, among many other capabilities.

An LED that can be integrated directly into computer chips

Light-emitting diodes—LEDs—can do way more than illuminate your living room. These light sources are useful microelectronics too.

Smartphones, for example, can use an LED proximity sensor to determine if you’re holding the phone next to your face (in which case the screen turns off). The LED sends a pulse of light toward your face, and a timer in the phone measures how long it takes that light to reflect back to the phone, a proxy for how close the phone is to your face. LEDs are also handy for distance measurement in autofocus cameras and gesture recognition.

One problem with LEDs: It’s tough to make them from . That means LED sensors must be manufactured separately from their device’s silicon-based processing chip, often at a hefty price. But that could one day change, thanks to new research from MIT’s Research Laboratory of Electronics (RLE).

Virgin Galactic traces SpaceShipTwo launch abort to bad computer connection

Virgin Galactic will fly again when VSS Unity is ready.

A bad computer connection foiled Virgin Galactic’s attempt to reach space over the weekend, company officials said.

VSS Unity, Virgin Galactic’s newest SpaceShipTwo vehicle, lifted off Saturday morning (Dec. 12) from New Mexico’s Spaceport America beneath the wings of its carrier airplane, VMS Eve.

LED lights found to kill coronavirus: Global first in fight against COVID-19

Am I reading this wrong? Sunelight is literally a cure / weapon against corona? Or am I missing something / making an incorrect logical link?

Researchers from Tel Aviv University (TAU) have proven that the coronavirus can be killed efficiently, quickly, and cheaply using ultraviolet (UV) light-emitting diodes (UV-LEDs). They believe that the UV-LED technology will soon be available for private and commercial use.

This is the first study conducted on the disinfection efficiency of UV-LED irradiation at different wavelengths or frequencies on a virus from the family of coronaviruses. The study was led by Professor Hadas Mamane, Head of the Environmental Engineering Program at TAU’s School of Mechnical Engineering, Iby and Aladar Fleischman Faculty of Engineering. The article was published in November 2020 issue of the Journal of Photochemistry and Photobiology B: Biology.

“The entire world is currently looking for effective solutions to disinfect the coronavirus,” said Professor Mamane. “The problem is that in order to disinfect a bus, train, sports hall, or plane by chemical spraying, you need physical manpower, and in order for the spraying to be effective, you have to give the chemical time to act on the surface. Disinfection systems based on LED bulbs, however, can be installed in the ventilation system and air conditioner, for example, and sterilize the air sucked in and then emitted into the room.

Bullets bounce off nanotubes

Circa 2007

Robocops could soon leave the realm of science fiction thanks to a new bullet-proof material proposed by engineers in Australia. According to computer simulations done by the team, bullets would be no match for vests made of the material, and would simply bounce off owing to the high elasticity of the nanotubes. The researchers claim that the material, which has not been made yet, would be a great improvement on existing anti-ballistic clothing that stop bullets from penetrating by spreading the bullet’s force — something that can still cause serious injury (Nanotechnology 18 475701).

3D vortex rings appear in a bulk magnet

Researchers have observed three-dimensional magnetic vortex rings in a real-world magnetic material for the first time. Contrary to theoretical predictions, these rings – which are spin configurations within the material’s bulk – are remarkably stable and could move through the material like smoke rings move through air. If such movement can be controlled, they might have applications in energy-efficient 3D data storage and processing.

In a ferromagnetic material, the spatial distribution of the local magnetization is responsible for the material’s magnetic properties. These spatial distributions can be very complex, and intricate magnetic “textures” are behind many modern technologies, including hard disk drives. A vortex is one such distribution, and it forms when the material’s magnetization circulates around a central core.

Vortex rings are more sophisticated still, and occur naturally in physical systems such as fluids, plasmas and turbulent gases in the Earth’s atmosphere. However, while they have long been predicted to exist in ferromagnets, they have never been observed there until now.

How Can We Fall Asleep More Easily? Neuralink 2021 And Beyond [Part 2]

Hey it’s Han from WrySci HX with Part 2 of a four part series on sleep and brain computer interfaces such as Neuralink. We’ll look at what we know about sleep and how BCIs might be able to help us in the future, 2021 and beyond. This isn’t a topic I’ve seen much about so I decided to see what was up. This second part is on sleep regulation (aka how we fall asleep, and hopefully how we can fall asleep more easily in the future) and sleeping with only certain parts of the brain, while the next ones will cover sleep and dream theories.

Proving the Existence of the Quark-Gluon Plasma With Gravitational Waves

Computer models of merging neutron stars predicts new signature in the gravitational waves to tell when this happens.

Neutron stars are among the densest objects in the universe. If our Sun, with its radius of 700,000 kilometers were a neutron star, its mass would be condensed into an almost perfect sphere with a radius of around 12 kilometers. When two neutron stars collide and merge into a hyper-massive neutron star, the matter in the core of the new object becomes incredibly hot and dense. According to physical calculations, these conditions could result in hadrons such as neutrons and protons, which are the particles normally found in our daily experience, dissolving into their components of quarks and gluons and thus producing a quark-gluon plasma.

This simulation shows the density of the ordinary matter (mostly neutrons) in red-yellow. Shortly after the two stars merge the extremely dense center turns green, depicting the formation of the quark-gluon plasma.
