A new login authentication approach could improve the security of current biometric techniques that rely on video or images of users' faces. Known as Real-Time Captcha, the technique uses a unique 'challenge' that's easy for humans -- but difficult for attackers who may be using machine learning and image generation software to spoof legitimate users.
With their insensitivity to decoherence what are known as Majorana particles could become stable building blocks of a quantum computer. The problem is that they only occur under very special circumstances. Now researchers have succeeded in manufacturing a component that is able to host the sought-after particles.
A team of researchers has demonstrated a new method for splitting light beams into their frequency modes, work that could spur advancements in quantum information processing and distributed quantum computing.
Players of the competitive esports video game League of Legends showed no change in testosterone during game play, researchers have found.
Quantum entanglement is a key feature of a quantum computer. Using conventional methods is hard since they require a large number of repeated measurements. Scientists have developed a novel method where in many cases even a single experimental run suffices to prove the presence of entanglement.
In a significant step forward for quantum computing in silicon - the same material used in today's computers -- a team has successfully coupled a single electron's quantum information, or spin, to a particle of light, or photon. The goal is to use light to carry quantum information on a futuristic quantum computing chip.
Special-purpose chip that performs some simple, analog computations in memory reduces the energy consumption of binary-weight neural networks by up to 95 percent while speeding them up as much as sevenfold.
A special-purpose chip hardwired to implement elliptic-curve cryptography in general and the datagram transport layer security protocol in particular reduces power consumption by 99.75 percent and increases speed 500-fold, to help enable the internet of things.
By mixing metal ions and organic ligands, scientists have developed a process for the 3-D printing of metal structures that are smaller than ever before.
Researchers have long been applying AI to protect wildlife. Initially, computer scientists were using AI and game theory to anticipate the poachers' haunts, and now they have applied artificial intelligence and deep learning to spot poachers in near real-time.
In the next 30 years, there is a one-in-three chance that California's Hayward fault will rupture with a 6.7 magnitude or higher earthquake. Scientists have used some of the world's most powerful supercomputers to model ground shaking for a magnitude 7.0 earthquake on the Hayward fault and show more realistic motions than ever before.
Miniature glasses have revealed a new form of 3-D vision in praying mantises that could lead to simpler visual processing for robots.
New research shows how robots can autonomously construct abstract representations of their surroundings and use them to plan for multi-step tasks.
Spoiling old dogs in their twilight years by retiring them to the sofa and forgiving them their stubbornness or disobedience, doesn’t do our four-legged friends any good. Regular brain training and lifelong learning create positive emotions and can slow down mental deterioration in old age. Physical limitations, however, often do not allow the same sort of training as used in young dogs. In a new study, a team of researchers led by cognitive biologists propose computer interaction as a practical alternative. In the training lab, old dogs responded positively to cognitive training using educational touchscreen games.
Conversational agents such as Siri, Alexa and Cortana are great at giving you the weather, but are flummoxed when asked for unusual information, or follow-up questions. By adding humans to the loop researchers have created a conversational agent that is tough to stump. It's not the first chatbot to use human brainpower to answer a broad range of questions. What sets it apart is humans are simultaneously training its artificial intelligence, making it gradually less dependent on people.
While the trusty 'like' button is still the most popular way to signal approval for Facebook posts, a computer model may help users and businesses navigate the increasingly complicated way people are expressing how they feel on social media.
A new study shows terahertz data links are possible even without direct line-of-sight between transmitter and receiver, a promising finding for future ultra-high-capacity terahertz data networks.
Researchers discovered ways to further improve computing efficiency using management tools for cloud-based light-weight virtual machine replacements called containers.
The tiny worm C. elegans is the only living being whose neural network has been analyzed completely. It can therefore be transferred to a computer, creating a virtual copy of the worm which behaves in exactly the same way to external stimuli. Such a 'virtual worm' can learn amazing tricks -- its neural network can even be used to balance a pole, which is a standard control problem in computer science.
The biology teacher's pedagogical toolbox is evolving. Bright colors, replicating computer code and a digital petri dish bring evolution science to life for students.
