Diodes —also known as rectifiers—allow electric current to flow in just one direction. More than 40 years ago, scientists proposed miniaturizing diodes and other electronic components down to the size of single molecules, an idea that eventually helped give birth to the field of molecular electronics, which could help push computing beyond the limits of conventional silicon devices. [See “Whatever Happened to the Molecular Computer?” IEEE Spectrum, October 2015]

Scientists at the University of Georgia and Ben-Gurion University of the Negev in Israel used DNA to fashion the new diode. The breakthroughs in genetics developed to sequence the human genome have now made it relatively easy to precisely manufacture and manipulate DNA, which makes the molecule a leading candidate for use in molecular electronics.

DNA’s double helix is made of paired strands of molecules known as bases. The new diode is only 11 base pairs long. (Typically, DNA is 0.34 nanometers long per base pair.)

Toyota USA thinks one of the best ways to unlock your car door, is with your face.

SCIENTISTS in China are planning to open a mass-cloning factory by the end of the year.

Three days ago, when Global Equities Research projected more than 300,000 reservations for the Tesla Model 3 electric car by the start of this week, that number seemed outlandish.

And yet, by the end of Saturday, the global total had reached 276,000, according to a tweet by Tesla CEO Elon Musk.

When the Model 3 was first unveiled in California on Thursday evening, the number of deposits that day alone had already crossed 100,000.

Researchers with the University of Cambridge say they have the first real evidence of a new state of matter, some 40 years after it was first theorized.

Known as “quantum spin liquid,” the matter states causes normally unbreakable electrons to fracture into pieces, called “Majorana fermions.” These fermions are an important discovery: Physicists believe the material is crucial to further develop quantum computing. Computers employing Majorana fermions would be able to carry out calculations beyond the scope of modern computers quickly, they say.

Quantum spin liquid explains some of the odd behaviors inside magnetic materials. In these materials, the electrons should behave like small bar magnets, all aligning towards magnetic north when a material is cooled. But not all magnetic materials do this — if the material contains quantum spin liquid, the electrons don’t all line up and become entangled.

Travel to the past is probably impossible. But to the future? That’s a different story. Cathal O’Connell considers the feasibility of physics.

In 2009 the British physicist Stephen Hawking held a party for time travellers — the twist was he sent out the invites a year later. (No guests showed up).

And the company behind it is ran by a brilliant 26 year old hacker.

Researchers have just discovered evidence of a mysterious new state of matter in a real material. The state is known as ‘quantum spin liquid’ and it causes electrons — one of the fundamental, indivisible building blocks of matter — to break down into smaller quasiparticles.

Scientists had first predicted the existence of this state of matter in certain magnetic materials 40 years ago, but despite multiple hints of its existence, they’ve never been able to detect evidence of it in nature. So it’s pretty exciting that they’ve now caught a glimpse of quantum spin liquid, and the bizarre fermions that accompany it, in a two-dimensional, graphene-like material.

“This is a new quantum state of matter, which has been predicted but hasn’t been seen before,” said one of the researchers, Johannes Knolle, from the University of Cambridge in the UK.

This could definitely lead to other areas being controlled which could impact how companies can collect even demographics and profile online users for online ads, etc. Also, makes me wonder if we could even see a clamping down on how malls, stores, etc. collect data about consumers. I see major trickle down impacts from this.

The new rules make it nearly impossible for ISPs to track any information about your online activities, other than for network maintenance purposes.
