In a technique known as DNA origami, researchers fold long strands of DNA over and over again to construct a variety of tiny 3D structures, including miniature biosensors and drug-delivery containers. Pioneered at the California Institute of Technology in 2006, DNA origami has attracted hundreds of new researchers over the past decade, eager to build receptacles and sensors that could detect and treat disease in the human body, assess the environmental impact of pollutants, and assist in a host of other biological applications.

Although the principles of DNA origami are straightforward, the technique’s tools and methods for designing new structures are not always easy to grasp and have not been well documented. In addition, scientists new to the method have had no single reference they could turn to for the most efficient way of building DNA structures and how to avoid pitfalls that could waste months or even years of research.

That’s why Jacob Majikes and Alex Liddle, researchers at the National Institute of Standards and Technology (NIST) who have studied DNA origami for years, have compiled the first detailed tutorial on the technique. Their comprehensive report provides a step-by-step guide to designing DNA origami nanostructures, using state-of-the-art tools. Majikes and Liddle described their work in the Jan .8 issue of the Journal of Research of the National Institute of Standards and Technology.

Wi-Fi 6E devices are now being certified by the Wi-Fi Alliance. Smartphones, PCs, and laptops are expected in the first quarter of 2021, while TVs and VR devices should follow in the second quarter of 2021.

Hyundai and Apple teaming up to challenge Tesla? 😃

Apple and Hyundai plan to sign a deal that would lead to a “beta” version of an Apple electric vehicle as early as 2022, according to a Sunday report from Reuters.

Reuters cited a report from Korea IT News that said the companies are planning to sign a deal by March 2021 to partner on the self-driving electric cars, according to a Sunday report from Korea IT News.

The core section of China’s space station is scheduled to launch in the next several months, the first of 11 missions carrying lab elements, cargo, and astronauts to the fledgling outpost over the next two years, according to Chinese space program officials.

The launch of the first element of the Chinese station is one of more than 40 missions scheduled this year by China Aerospace Science and Technology Corp., or CASC, China’s largest state-owned aerospace contractor.

Scientists have recently discovered a totally new type of chemical bond – and it’s way stronger than it has any right to be.

The new type of bond shows that the divide between powerful covalent bonds, which bind molecules together, and weak hydrogen bonds, which form between molecules and can be broken by something as simple as stirring salt into a glass of water, isn’t as clear as chemistry textbooks would suggest.

Think back to that high-school chemistry class, and you’ll remember that there are different types of bonds that link atoms together into molecules and crystal structures.

Gene therapies are opening up possibilities that were once reserved for science fiction.

At Harvard University, Professor of Genetics David Sinclair says he believes it’s possible to unlock the fountain of youth, and gene therapy is the key.
