Electro-optical device provides solution to faster computing memories and processors

Posted by in categories: computing, engineering, nanotechnology

The first ever integrated nanoscale device which can be programmed with either photons or electrons has been developed by scientists in Harish Bhaskaran’s Advanced Nanoscale Engineering research group at the University of Oxford.

In collaboration with researchers at the universities of Münster and Exeter, scientists have created a first-of-a-kind electro– which bridges the fields of optical and electronic computing. This provides an elegant solution to achieving faster and more energy efficient memories and processors.

Computing at the has been an enticing but elusive prospect, but with this development it’s now in tangible proximity. Using light to encode as well as transfer information enables these processes to occur at the ultimate speed limit—that of light. While as of recently, using light for certain processes has been experimentally demonstrated, a compact device to interface with the electronic architecture of traditional computers has been lacking. The incompatibility of electrical and light-based computing fundamentally stems from the different interaction volumes that electrons and photons operate in. Electrical chips need to be small to operate efficiently, whereas need to be large, as the wavelength of light is larger than that of electrons.

CRISPR-Switch regulates sgRNA activity

Posted by in categories: bioengineering, biotech/medical

CRISPR-Cas9 is an efficient and versatile tool for genome engineering in many species. However, inducible CRISPR-Cas9 editing systems that regulate Cas9 activity or sgRNA expression often suffer from significant limitations, including reduced editing capacity, off-target effects, or leaky expression. Here, we develop a precisely controlled sgRNA expression cassette that can be combined with widely-used Cre systems, termed CRISPR-Switch (SgRNA With Induction/Termination by Cre Homologous recombination). Switch-ON facilitates controlled, rapid induction of sgRNA activity. In turn, Switch-OFF-mediated termination of editing improves generation of heterozygous genotypes and can limit off-target effects. Furthermore, we design sequential CRISPR-Switch-based editing of two loci in a strictly programmable manner and determined the order of mutagenic events that leads to development of glioblastoma in mice. Thus, CRISPR-Switch substantially increases the versatility of gene editing through precise and rapid switching ON or OFF sgRNA activity, as well as switching OVER to secondary sgRNAs.

Vitamin C & Cancer — Health & Disease Masterkey (Part 3)

Posted by in categories: biotech/medical, health

Do you know why only Vitamin C in the form of L-ascorbic acid is truly effective against cancer?


The Molecular Structure of Ascorbic Acid – MasterKey to Health & Disease

Most living organisms including plants, insects and animals produce ascorbic acid. Ascorbic acid exists naturally in the form of L-ascorbic acid [24]. In physiological pH, L-ascorbic acid exists predominantly in the ionic form of L-ascorbate.

What If Technology Causes Some People to Live Forever?

Posted by in categories: life extension, neuroscience

This sounds like a roundabout way of saying that the uploaded minds might be seen as superhuman, even though, as Minerva and Rorheim observe, “it’s not clear whether you would survive in any meaningful sense if you were copied several times over.” If you didn’t, something that used to be you might exist and be cognitively superior to the common run of humanity but the “you-ness” is gone.

The authors also warn, “We can be pretty certain, for instance, that rejuvenation would widen the gap between the rich and poor, and would eventually force us to make decisive calls about resource use, whether to limit the rate of growth of the population, and so forth.”

Such considerations as limiting the “rate of growth” of the population may relate to a controversy in 2012 involving a paper written by Dr. Minerva and Dr. Alberto Giubilini:

Organ transplant candidates

Posted by in category: biotech/medical

This statistic displays the number of organ transplant candidates in the United States by organ, as of as of September 25, 2019. At this moment, there were 230 candidates in the country waiting for an intestine donation. Organ donation can be given through both a deceased and living donor if blood and oxygen are flowing through the organs until the time of recovery to ensure viability. There are over 120,000 people in the country waiting for an organ transplant.

Stephen Hawking’s Final Research Paper Predicted the End of the Universe

Posted by in categories: cosmology, space travel

Before his death, Stephen Hawking submitted a research paper that predicts the end of the world.


Just two weeks before his death, renowned physicist Stephen Hawking submitted a research paper that suggests parallel universes and predicts the end of this one.

Hawking and his co-author Thomas Hertog published their research in “A Smooth Exit from Eternal Inflation,” detailing how scientists may also be able to detect other universes using a spaceship. According to Hertog, Hawking finished writing the paper from his deathbed, leaving behind a final legacy that is worthy of the Nobel Prize.

SQUID drone is launched by a cannon from a moving truck [video]

Posted by in category: drones

Not only are people still coming up with new drone applications, but they are also still coming up with new drone designs. How about the SQUID drone that is launched from a cannon mounted in the bed of a moving truck. Once the SQUID reached a certain altitude, it deploys and flies away like a ‘normal’ drone.

Jet-powered VTOL drone is like a quadcopter on steroids

Posted by in category: drones

While propeller planes certainly do have their place, sometimes the extra speed and thrust of a jet engine is what’s really needed. Dallas, Texas-based FusionFlight has applied that sort of thinking to quadcopter-style drones, resulting in the AB5 JetQuad.

According to the company, the AB5 is “the world’s smallest and most powerful jet-powered drone with vertical take-off and landing [VTOL] capabilities.”
