Jumping spiders and flying bees: The rise of bio inspired microrobots

Researchers at the University of Manchester in the U.K. developing jumping robot spiders and swarms of robotic bees have trained a species of jumping spider to jump different distances and heights, recording every movement in extreme detail using high-resolution cameras. If robots can be developed that can perfectly mimic the way biological spiders jump, they can be used for applications in complex engineering and manufacturing, and can be deployed in unknown or dangerous environments, says Manchester researcher professor Mostafa Nabawy. Nabawy also is developing flying robot bees, with the ultimate goal of creating a machine that can fly independently. Nabawy notes these technologies can “be used for many different applications, including improving the current aerodynamic performances of aircraft.”

Researchers harness brain waves to reconstruct images of what we perceive

Neuroscientists at the University of Toronto Scarborough (U of T Scarborough) have for the first time digitally reconstructed images of what people perceive based on brain waves recorded via electroencephalogram (EEG). “When we see something, our brain creates a mental percept, which is essentially a mental impression of that thing,” says U of T Scarborough’s Dan Nemrodov. “We were able to capture this percept using EEG to get a direct illustration of what’s happening in the brain during this process.” EEG-linked test subjects were displayed images of faces as their brain activity was recorded, and then machine-learning algorithms digitally recreated the images. “EEG captures activity at the millisecond scale, Nemrodov notes. “So we can see with very fine detail how the percept of a face develops in our brain using EEG.” The team estimated that it takes the brain about 170 milliseconds to form a good representation of a face.

Physicists create new form of light

Researchers at the Massachusetts Institute of Technology, Harvard University, and elsewhere have demonstrated the successful interaction of photons, which could clear a path toward using light particles in quantum computing. Their controlled experiments showed that when shining a weak laser beam through a dense cloud of ultracold rubidium atoms, the photons bound together in pairs or triplets, suggesting an attraction occurring among them. The researchers also measured the photonic phase before and after traveling through the cloud, and they noted as the three-photon particles exited the atom cloud simultaneously, their phase was shifted compared to when the photons did not interact at all, and was three times larger than the phase shift of two-photon molecules. The team says photons that have interacted with each other, in this case via an attraction between them, can be considered strongly correlated, or entangled, which is essential for any quantum computing bit.

Universities Rush to Roll Out Computer Science Ethics Courses

U.S. universities are starting to offer ethics courses relating to computer science, with the hope of training next-generation technologists and policymakers to weigh the social and moral ramifications of innovations before they are commercialized. One factor driving this trend is the popularization of tools such as machine learning, which have the potential to significantly change human society. “We need to at least teach people that there’s a dark side to the idea that you should move fast and break things,” says New York University’s Laura Noren. “You can patch the software, but you can’t patch a person if you…damage someone’s reputation.” A joint Harvard University-Massachusetts Institute of Technology course concentrates on the ethical, policy, and legal implications of artificial intelligence. The course also covers the proliferation of algorithmic risk scores that use data to predict whether someone is likely to commit a crime.

Centre for Machine Intelligence launched to help build a smarter and safer society

The University of Southampton in the U.K. recently launched the Center for Machine Intelligence (CMI), bringing together researchers and practitioners in artificial intelligence, machine learning, and autonomous systems to develop a coherent approach to research and technology transfer. Discussions at the launch event focused on these various technologies’ application in large-scale Internet of Things systems and in the insurance and social care sectors. Research groups within the CMI will focus on the theoretical aspects of machine intelligence, including the Agents, Interaction, and Complexity group, and the Vision, Learning, and Control group. “The formation of the CMI is an important next step at a time of great advances in this field and we look forward to working with industry, policymakers and the general public as we address both national and global challenges,” says Southampton professor Sarvapali Ramchurn, who will head the CMI.

NIST’s Superconducting Synapse May Be Missing Piece for ‘Artificial Brains’

Researchers at the U.S. National Institute of Standards and Technology (NIST) say they have constructed a superconducting “synapse” switch that “learns” in the manner of a biological system and which could link processors and store memories in future computers that operate like the human brain. The team views the synapse as a key ingredient for neuromorphic computers, and it consists of a compact metallic cylinder 10 micrometers in diameter. The device processes incoming electrical spikes to tailor spiking output signals, with processing based on a flexible internal design that is experientially or environmentally tunable. The NIST synapse also fires 1 billion times a second–much more than a human synapse–while using only about one-10,000th as much energy. The researchers note the synapse would be employed in neuromorphic systems built from superconducting components, which can transmit electricity without resistance, with data transmitted, processed, and stored in units of magnetic flux.

The Top Seven Programming Languages of 2018

Coding Dojo recently released a list of the top seven most in-demand programming languages coders should be aware of over the next year. “New and in-demand programming languages, frameworks, and technologies can emerge, rise to fame, and then fade away in the course of a few years,” which means developers should be constantly learning new skills, says Coding Dojo’s Speros Misirlakis. The company analyzed data from Indeed on 25 programming languages, stacks, and frameworks to determine which were the seven most in demand by employers. The analysis found that Java is the most in-demand language, with 68,000 jobs in 2017, but that figure is expected to decrease to 62,000 in 2018. Meanwhile, Python is expected to grow from 41,000 jobs in 2017 to 46,000 jobs in 2018. JavaScript ranked third, with 40,000 jobs in 2017, but is projected dip to 38,000 in 2018. C++ and C# were fourth and fifth, respectively, followed by PHP and Perl.
