How our tastes influence our creativity

Posted by in categories: computing, neuroscience

The more we like our ideas, the faster we give them shape. But to be creative, we need to focus on out-of-the-box thinking. This is what Alizée Lopez-Persem and Emmanuelle Volle, Inserm researchers at Paris Brain Institute, showed in a new study published in American Psychologist.

Using a behavioral study and a computational model to replicate the different components of the , the researchers explain how individual preferences influence the speed of the emergence of new ideas and their degree of . These preferences also determine which ideas we choose to exploit and communicate to others.

What drives us to develop new ideas rather than settling for standard methods and processes? What triggers the desire to innovate at the risk of sacrificing time, energy, and reputation for a resounding failure? Creativity is based on complex mechanisms that we are only beginning to understand and in which motivation plays a central role. But pursuing a goal is not enough to explain why we favor some ideas over others and whether that choice benefits the success of our actions.

A quantum leap in mechanical oscillator technology

Posted by in categories: computing, cosmology, quantum physics

Over the past decade, scientists have made tremendous progress in generating quantum phenomena in mechanical systems. What seemed impossible only fifteen years ago has now become a reality, as researchers successfully create quantum states in macroscopic mechanical objects.

By coupling these mechanical oscillators to light photons—known as “optomechanical systems”—scientists have been able to cool them down to their lowest energy level close to the , “squeeze them” to reduce their vibrations even further, and entangle them with each other. These advancements have opened up new opportunities in , compact storage in quantum computing, fundamental tests of quantum gravity, and even in the search for dark matter.

In order to efficiently operate optomechanical systems in the quantum regime, scientists face a dilemma. On one hand, the mechanical oscillators must be properly isolated from their environment to minimize ; on the other hand, they must be well-coupled to other such as electromagnetic resonators to control them.

Editorial: Augmentation of Brain Function: Facts, Fiction and Controversy

Posted by in categories: biotech/medical, computing, cyborgs, virtual reality

This research topic consists of 148 articles on various aspects of brain augmentation contributed by more than 600 authors. At the time of writing, the articles have been viewed online more than 1.3 million times and received plentiful citations in the scientific literature. The topic won the 2017 Frontiers Spotlight Award.

The topic theme, “Augmentation of brain function,” is an umbrella term for the approaches from different disciplines, aimed at the improvement of brain performance in both healthy people and patients suffering from neurological disabilities. Functions of the brain that scientists hope to augment belong to sensory, motor and cognitive domains. Brain enhancements could be achieved pharmacologically or using neurostimulation. Functional improvements can be also achieved with brain training techniques that employ modern technologies like computer games and virtual reality. Furthermore, brain performance can be augmented using brain-machine interfaces (BMIs), the pathways that connect neuronal circuits to external assistive devices, such as limb prostheses, exoskeletons, and communication aids. In addition to sending commands to external devices, BMIs can enable bidirectional communications, where artificial sensory signals are delivered to the brain while information is being decoded from neural recordings.

Even though many of the brain-augmenting ideas sound like science fiction, the topic authors feel optimistic about most of them. The overall consensus is that brain performance can be improved with artificial components, and this approach will lead to practical applications in the not-too-distant future. Many of the techniques covered in the topic, for example BMIs and noninvasive stimulation, have already experienced an explosive development. While expectations are high for the augmentation approaches, philosophers are warning about the ethical issues related to technologies that interfere with the mind, possibly in unpredictable ways. Although some of these concerns seem far-fetched, it is important that ethical standards are kept high as these revolutionary brain-augmenting methods are being developed.

Quantum Echoes: A Revolutionary Method to Store Information as Sound Waves

Posted by in categories: computing, quantum physics

Quantum computing, just like traditional computing, requires a method to store the information it uses and processes. In the computer you’re using right now, information—whether it be photos of your dog, a reminder about a friend’s birthday, or the words you’re typing into your browser’s address bar—must be stored somewhere. Quantum computing, a relatively new field, is still exploring where and how to store quantum information.

DARPA Aims to Develop New Synthetic Quantum Materials That Could Radically Improve Quantum Computing

Posted by in categories: computing, nanotechnology, quantum physics

The Defense Advanced Research Projects Agency (DARPA) has announced a new program it says will develop synthetic metamaterials that could lead to breakthroughs in quantum computing and information science.

Called the Synthetic Quantum Nanostructures program, or SynQuaNon, the new DARPA initiative “aims to address this challenge with a fundamental science effort that seeks to develop synthetic metamaterials to enable enhanced functionalities and novel capabilities,” read a statement issued by the agency this week.

The program aims to produce a range of new quantum materials that will have a variety of uses in quantum computing and other information science applications.

ESA’s Gaia satellite spots ‘retired stars’ passing through young star-forming area

Posted by in categories: computing, physics, space

These waves can reach heights comparable to stacking three suns on top of each other.

Astronomers have discovered a strange star system with “monster” tidal waves breaking on one of its stars. Astrophysicists from the Center for Astrophysics | Harvard & Smithsonian (CfA) developed new computer models to better understand the impact of huge surface waves.

The new models reveal “titanic waves” created by the tides of a smaller companion star to be repeatedly crashing on the colossal star in the system. This phenomenon has never been detected on a star, making it a significant discovery.

Quantum material exhibits ‘non-local’ behavior that mimics brain function

Posted by in categories: computing, information science, mathematics, neuroscience, quantum physics

We often believe computers are more efficient than humans. After all, computers can complete a complex math equation in a moment and can also recall the name of that one actor we keep forgetting. However, human brains can process complicated layers of information quickly, accurately, and with almost no energy input: recognizing a face after only seeing it once or instantly knowing the difference between a mountain and the ocean.

These simple human tasks require enormous processing and energy input from computers, and even then, with varying degrees of accuracy.

Creating -like computers with minimal requirements would revolutionize nearly every aspect of modern life. Quantum Materials for Energy Efficient Neuromorphic Computing (Q-MEEN-C)—a nationwide consortium led by the University of California San Diego—has been at the forefront of this research.
