Researchers develop new variant of Maxwell’s demon at nanoscale

Posted by in categories: biological, nanotechnology, quantum physics

Maxwell’s demon is a machine proposed by James Clerk Maxwell in 1897. The hypothetical machine would use thermal fluctuations to obtain energy, apparently violating the second principle of thermodynamics. Now, researchers at the University of Barcelona have presented the first theoretical and experimental solution of a continuous version of Maxwell’s demon in a single molecule system. The results, published in the journal Nature Physics, have applications in other fields, such as biological and quantum systems.

“Despite its simplicity and the large amount of work in the field, this new variant of the classical Maxwell demon has remained unexplored until now,” notes F\xE8lix Ritort, professor from the Department of Fundamental Physics of the UB. “In this study, we introduced a system able to extract large amounts of work arbitrarily per cycle through repeated measurements of the state of a system.”

Unboxing The Mind Bending Wallpaper TV… — YouTube

Posted by in categories: electronics, mobile phones

The LG Wallpaper TV is the thinnest display I’ve ever seen or held. It’s thinner than a smartphone and I can easily pick up the 65-inch! It uses LG’s OLED technology so you’ve got super dark blacks, vibrant colors and the overall picture quality you’ve come to expect from OLED. Because the Wallpaper TV is so thin it connects to an external sound bar speaker for power and video connections. The speaker is louder than standard TV speakers and features Dolby Atmos capabilities.

Self-healing concrete uses fungus to fill cracks

Posted by in category: materials

If cracks in concrete can be fixed when they’re still tiny, then they can’t become large cracks that ultimately cause structures such as bridges to collapse. It is with this in mind that various experimental types of self-healing concrete have been developed in recent years. One of the latest utilizes a type of fungus to do the healing.

Scientists Freeze Atoms to Near Absolute Zero

Posted by in categories: food, particle physics, quantum physics

:oo.


We usually think of microwaves as waves that heat things up, usually leftover food, but did you know that they can also cool things down? For example, physicists recently decided to use them to freeze atoms, and attempts have been very successful: They managed to cool them down to within a millionth of a degree of absolute zero (–273.15°C or −459.67°F).

The University of Sussex team, led by Winifried Hensinger, had their results published in Physical Review Letters.

Powerful CRISPR cousin accidentally mutates RNA while editing DNA target

Posted by in category: biotech/medical

When researchers first reported 3 years ago that they had created base editors, a version of the powerful genome-editing tool CRISPR, excitement swirled around their distinct powers to more subtly alter DNA compared with CRISPR itself. But the weaknesses of base editors have become increasingly apparent, and a new study shows they can also accidentally mutate the strands of RNA that help build proteins or perform other key cellular tasks. Researchers say this could complicate developing safe therapies with the technology and hamper other research applications.

Human diseases from sickle cell to Tay-Sachs are caused by a single mutation to one of the four DNA bases—adenine, guanine, cytosine, and thymine—and CRISPR has often had difficulty swapping out the bad actors. That’s in part because CRISPR cuts double-stranded DNA at targeted places and then relies on finicky cell repair mechanisms to do the heavy lifting of inserting a corrected DNA sequence for a mutation. Base editors, in contrast, chemically change one DNA base into another with enzymes called deaminases, which doesn’t require a cut or help from the cell.

Base editors, which adapt key components of CRISPR to reach targeted places in the genome, have been shown to have many off-target effects on DNA. But until now, its effects on RNA, which contains three of the same bases as DNA, had escaped scrutiny. So J. Keith Joung, a pathologist and molecular biologist at the Massachusetts General Hospital in Boston, led a team that put base editors into human liver and kidney cells. Their finding: Deaminases can also alter RNA, the group reports today in.
