Chip-based optical tweezers manipulate microparticles and cells from a distance

Posted by in categories: biotech/medical, computing, tractor beam

Chip-based tractor beam Integrated optical tweezers use an intensely focused beam of light to capture and manipulate biological particles without damaging the cells.

Optical manipulation techniques are garnering increased interest for biological applications.


Optical manipulation techniques are garnering increased interest for biological applications. Researchers from Massachusetts Institute of Technology (MIT) have now developed a miniature, chip-based optical trap that acts as a “tractor beam” for studying DNA, classifying cells and investigating disease mechanisms. The device – which is small enough to fit in your hand – is made from a silicon-photonics chip and can manipulate particles up to 5 mm away from the chip surface, while maintaining a sterile environment for cells.

Thread#showTweet data-screenname= awiltschko data-tweet=1851327552490733686 dir= auto Well, we actually did it. We digitized scent. A fresh summer plum was the first fruit and scent to be fully digitized and reprinted with no human intervention. It smells great.

Holy moly, I’m still processing the magnitude of what we’ve done. And yet, it feels like as we cross this finish line we are instantly at a new starting line. I’ll have more to share about what’s in store that we’re building on top of this.

A huge HUGE congrats to the entire team across scientific, engineering, operational, and creative disciplines. It takes a village named Osmo to do this.

When, where and how to watch Leonid meteor shower?

Posted by in category: space

The earthlings are yet again going to experience the breathtaking celestial event known as Leonid meteor shower which will be active from November 3 to December 2 this year and peak overnight from November 16 to 17.

When Earth travels through the debris left behind by comet 55P/Tempel-Tuttle the Leonids are produced. It happens during its highly elliptical orbit around the Sun every 33 years, reported Space.

It is worth noting that the Leonids are regarded as some of the fastest meteors, zipping through the sky at 44 miles (71 kilometres) per second, as per NASA.

Plans must be made for the welfare of sentient AI, animal consciousness researchers argue

Posted by in category: robotics/AI

Computer scientists need to grapple with the possibility they will accidentally create sentient artificial intelligence (AI) — and to plan for those systems’ welfare, a new study argues.

The report published Thursday comes from an unusual quarter: specialists in the frontier field of animal consciousness, several of whom were signatories of the New York Declaration on Animal Consciousness.

Nanofibrils study successfully measures strength of spider web ‘super fibers’

Posted by in category: futurism

How small is “small?” Spider silk nanofibrils are just a few molecular layers thick, equivalent to approximately one ten-thousandth the diameter of a human hair. They’re invisible to the naked eye and cannot be seen under an ordinary microscope.
