OnePlus wireless ear buds offer good sound and value

Cord cutters are referred to usually as people who’ve dumped cable TV, either going only with off the air signals or using alternative services such as Netflix, YouTube and the like as ways to get their programming fixes.

But there’s another type of cord cutting that could be quite attractive to some consumers, and that’s the cutting of the cord between your smart device/music player/whatever and your headphones. It’s a legitimate cutting if, like me, you tend to get your cords tangled and twisted all the time.

Thermal camouflage disguises hot and cold

Thermal camouflage disguises hot and cold
Hunters don camouflage clothing to blend in with their surroundings. But thermal camouflage – or the appearance of being the same temperature as one’s environment – is much more difficult. Now researchers, reporting in ACS’ journal Nano Letters, have developed a system that can reconfigure its thermal appearance to blend in with varying temperatures in a matter of seconds.

China and Scientific Scandals

China and Scientific Scandals
China has more laboratory scientists than any other country, outspends the entire European Union on research and development, and produces more scientific articles than any other nation except the United States. But in its rush to dominance, China has stood out in another, less boastful way. (1)

A recent string of high-profile scandals over questionable or discredited research has driven home the point for China that to become a scientific superpower, it must first overcome a festering problem of scientific fraud.

Robot bloodhound tracks odors on the ground

Robot bloodhound tracks odors on the ground
Bloodhounds are famous for their ability to track scents over great distances. Now researchers have developed a modern-day bloodhound – a robot that can rapidly detect odors from sources on the ground, such as footprints. The robot, reported in ACS Sensors, could even read a message written on the ground using odors as a barcode.

Crumple up this keyboard and stick it in your pocket

Crumple up this keyboard and stick it in your pocket
Bendable portable keyboards for use with computers and other electronic devices are already on the market, but they have limited flexibility, and they’re fairly sizable when rolled up for transport. Now researchers have crafted an inexpensive keyboard that is so tough, flexible and thin that it can be crumpled up and tucked in a pocket without damaging it. The study appears in the journal ACS Applied Materials & Interfaces.

Watch: Caesar’s last breath and Einstein’s lost fridge

WASHINGTON— Are you breathing air molecules that were once exhaled by Caesar, Joan of Arc or Madame Curie? And why did Albert Einstein try to break into the refrigerator business? Writer Sam Kean, author of Caesar’s Last Breath and The Disappearing Spoon, explains in this video, in which Reactions partners with PBS to find America’s favorite book as part of the Great American Read:

Watch: E- textiles control home appliances with the swipe of a finger

Electronic textiles could allow a person to control household appliances or computers from a distance simply by touching a wristband or other item of clothing — something that could be particularly helpful for those with limited mobility. Now researchers, reporting in ACS Nano, have developed a new type of e-textile that is self-powered, highly sensitive and washable. A video of an e-wristband in action is available here.

No spring this year? No problem – it’s still time to clean up your tech stuff

spring cleaning
Despite a winter that seems to have pushed spring out of the way to make room for an early summer, the usual stuff you do during spring still need to be done.

This could be the first car wax job of the year, the final throwing out of all that Christmas wrapping you were hoping to use for re-gifting, or just the first mowing of the lawn. And according to IT security company ESET, there’s some stuff you can and maybe should be doing to help ensure your technology is brought into the new year as well, whether it be kicking and screaming or not.

Blackcurrant dye could make hair coloring safer, more sustainable

Blackcurrant dye could make hair coloring safer, more sustainable
Whether they’re trying to hide some gray or embrace a new or quirky color, people adore hair dyes. But some of these dyes may be harmful to humans and the environment. Now in a study appearing in ACS’ Journal of Agricultural and Food Chemistry, scientists report that they have developed a natural, non-toxic hair dye derived from blackcurrant skins that is as durable as conventional dyes and capable of sustaining hair color through multiple washings.

Preserving a painter’s legacy with nanomaterials

Preserving a painter's legacy with nanomaterials
Paintings by Vincent van Gogh, Pablo Picasso and Johannes Vermeer have been delighting art lovers for years. But it turns out that these works of art might be their own worst enemy — the canvases they were painted on can deteriorate over time. In an effort to combat this aging process, one group is reporting in ACS Applied Nano Materials that nanomaterials can provide multiple layers of reinforcement.

Watch: Chameleons are masters of nanotechnology

WASHINGTON—Chameleons are nature’s most talented masters of color. They use their unique color-changing abilities for all sorts of reasons. But how do they alter their hue? They wield a combination of pigments and specialized nano-scale crystals. In this video, Reactions explains how chameleons have mastered nanotech:

Step aside Superman, steel is no competition for this new material

Step aside Superman, steel is no competition for this new material
When it comes to materials, there is no question as to who wins the strongman competition. Spider silk is known as being the strongest fabric, and steel, ceramics and glass fibers are the best building materials. But now, researchers are reporting in ACS Nano that specially arranged nano-sized cellulose fibers are the strongest material of them all, in a move that might cause some to re-name Superman the “man of cellulose.”

Placeboism

Placeboism
Everyone knows (or ought to): Everything is getting better all the time. That’s certainly true in spring or early summer, when nature re-awakens after a long and cold winter but, just perhaps, not all the time.

And that’s why cunning politicians like to make big promises and have elections at those times.  That’s just one example of the placebo effect, the proclamation that “your vote counts.”

Battery-free ‘smart’ toys move closer to commercial reality (video)

battery-free-smart-toys-move-closer-to-commercial-reality-video
Rubber duckies could soon be at the forefront of an electronic revolution. In ACS Sustainable Chemistry & Engineering, scientists report they have used specialized nanogenerators that gather energy from mechanical vibrations to transform squeaky bathtub companions and other conventional children’s toys into ‘smart’ electronics. They say the finding could have broad commercial applications, leading to the development of battery-free, self-powered toys, medical sensors and other devices. Watch a video of prototype toys here.

Jeeves, the ashtray is full—buy a new (flying) car!

Jeeves, the ashtray is full -- buy a new (flying) car!
Are you ready to get your new (electric) flying machine? Perhaps you already know, it’s supposed to be coming to a store near you, soon:

Airbus is already working on several electric aircraft programs, including an autonomous electric VTOL aircraft, but now they are partnering with Audi and Italdesign to combine that with electric cars.
