Implanting diamonds with flaws offers key technology for quantum communications

Diamonds are prized for their purity, but their flaws might hold the key to a new type of highly secure communications.

Princeton University researchers are using to help create a communication network that relies on a property of subatomic particles known as their quantum state. Researchers believe such quantum information networks would be extremely secure and could also allow new quantum computers to work together to complete problems that are currently unsolvable. But scientists currently designing these networks face several challenges, including how to preserve fragile quantum information over long distances.

Now, researchers have arrived at a possible solution using synthetic diamonds.

Meta-analysis finds sustained benefits of neurofeedback for kids with ADHD

Fascinating findings: “1. Neurofeedback yields significant reductions in parent ratings of inattentive and hyperactive-impulsive symptoms. 2. These reductions persist for up to 2–12 months after neurofeedback ends. 3. Although medication has a larger initial effect, symptom reductions resulting from neurofeedback and medication may be comparable over a more extended time period.”


In neurofeedback treatment for ADHD, individuals learn to alter their typical pattern of brainwave activity, i.e., EEG activity, to one that is consistent with a focused and attentive state.

This is done by collecting EEG data from individuals as they focus on stimuli presented on a computer screen. Their ability to control the stimuli, e.g., keeping the smile on a smiley face keeping a video playing, depends on their maintaining an EEG state that reflects focused attention.

Over time, most individuals better at this. Supporters of neurofeedback argue that learning to alter EEG activity and focus better during training eventually generalizes to real-world tasks that require strong attention skills, e.g., reading, homework, etc.

A Free Education for All the World’s People Will Save our Species

In terms of moral, social, and philosophical uprightness, isn’t it striking to have the technology to provide a free education to all the world’s people (i.e. the Internet and cheap computers) and not do it? Isn’t it classist and backward to have the ability to teach the world yet still deny millions of people that opportunity due to location and finances? Isn’t that immoral? Isn’t it patently unjust? Should it not be a universal human goal to enable everyone to learn whatever they want, as much as they want, whenever they want, entirely for free if our technology permits it? These questions become particularly deep if we consider teaching, learning, and education to be sacred enterprises.


When we as a global community confront the truly difficult question of considering what is really worth devoting our limited time and resources to in an era marked by global catastrophe, I always find my mind returning to what the Internet hasn’t really been used for yet — and what was rumored from its inception that it should ultimately provide — an utterly and entirely free education for all the world’s people.

In regard to such a concept, Bill Gates said in 2010:

“On the web for free you’ll be able to find the best lectures in the world […] It will be better than any single university […] No matter how you came about your knowledge, you should get credit for it. Whether it’s an MIT degree or if you got everything you know from lectures on the web, there needs to be a way to highlight that.”

Dark Matter ‘Test’ Will Either Prove Its Existence or Modify Gravity

For something that supposedly takes up 80 percent of the total mass of the universe, we don’t know a whole lot about dark matter. Sometimes the lightless stuff reveals hints about its shape; other times it completely thwarts any evidence supporting its existence. Since we can’t observe it first-hand, we rely on indirect means to suss out information about it, like watching the interactions between other forms of matter. Now, scientists have developed a new “test” to make those investigations more definitive, leading us closer to answering the question: Is dark matter even real? And if it’s not, then is everything we know about gravity wrong?

In a study, published Monday in Physical Review Letters, a team of scientists from the University of Bonn that also includes Hubble Fellow Marcel S. Pawlowski, Ph.D. of the University of California, Irvine, introduce a computer model that can simulate how certain small galaxies should move if dark matter exists. Though dark matter does not absorb or emit light, it still interacts with visible matter through gravity, so it’s expected to make the stars around galaxies move in specific ways.

Pawlowski explains to Inverse in an email that within the little galaxies in question — satellite “dwarf” galaxies, crowding around the edges of big galaxies like the Milky Way — the acceleration of stars speeding around the galaxy’s center is described by a term called the radial acceleration relation, or RAR. “With the new study, we simulate such dwarf galaxies under the assumption of the ‘standard’ dark matter model, [to] determine what kind of behavior would be expected for the dwarfs,” he says. “We find that the simulated dwarf galaxies largely continue the RAR to lower accelerations.” Now that they know how those dwarf galaxies are supposed to move if dark matter exists, they can compare the simulations to real-life data on the movement of those galaxies.

This video is the twelfth and final in a multi-part series discussing computing. In this video, we’ll be discussing the future of computing, more specifically – the evolution of the field of computing and extrapolating forward based on topics we’ve discussed so far in this series!

[0:31–5:50] Starting off we’ll discuss, the 3 primary eras in the evolution of the field of computing since its inception, the: tabulating, programming and cognitive eras.

Afterwards, we’ll discuss infinite computing, a paradigm that incorporates cloud computing and the principles of heterogenous architecture that is accelerating the transition to cognitive computing.

Finally, to wrap up, we’ll discuss the future of computing, ubiquitous computing, fueled by the rise of abundant, affordable and smart computing devices, where computing is done using any device, in any location and in any format.

You’ll be able to tour the Red Planet habitat in virtual reality and view a scale model of the sci-fi living space at the Goodwood Festival of Speed next month.

China to crack down on fraud in scandal-hit scientific research amid ZTE wrangle

China has issued the first national guidelines to enforce academic integrity in scientific research and vowed to punish academics and institutes for misconduct such as plagiarism and fabrication of data.


Researchers and institutes involved in misconduct including plagiarism, fabrication of data and research conclusions, ghostwriting and peer review manipulation will face severe punishments, Xinhua reported.

Scandals involving plagiarism and fabrication of research findings have become more prevalent in recent years. Springer Nature last year retracted 107 papers published in Tumor Biology between 2012 and 2017 after an investigation found the authors had supplied the journal’s editors with made-up contact information for third-party reviewers.

After the ZTE ban, media and online commenters also recalled a scandal from 2006 over a much-hyped digital signal processing chip, dubbed the Hanxin, or Chinese chip, which was later exposed as a fraud.
