Robots Appear More Persuasive When Pretending to be Human
Recent technological breakthroughs in artificial intelligence have made it possible for machines, or bots, to pass as humans. A team of researchers conducted an experiment to study how people interact with bots whom they believe to be human, and how such interactions are affected once bots reveal their identity.
DNA as Tool to Build Graphene Circuits
Graphene is a groundbreaking material in the nanotechnology field, but it has characteristics that limit its potential applications. A research team is investigating ways to incorporate DNA nanotechnology as a construction tool to assemble graphene in new ways that could make the material more useful in electronic devices, among other applications.
Mobile 3D printing robots could fix bridges on Earth, Mars
A multidisciplinary robotics team is designing autonomous systems for 3D printers on robotic arms attached to mobile, roving platforms.
Look out, invasive species: The robots are coming
Invasive species control is notoriously challenging, especially in lakes and rivers where native fish and other wildlife have limited options for escape. Using biomimetic robots to understand and modify animal behavior demonstrates how robotic fish can be a valuable tool in the fight against one of the world's most problematic invasive species, the mosquitofish.
Wearable motion sensors could save unborn babies
The thump, thump of a baby's heartbeat is a milestone in any pregnancy. Now, researchers have developed a technique that could allow expectant parents to hear their baby's heartbeat continuously at home with a non-invasive and safe device that is potentially more accurate than any fetal heartrate monitor currently available in the market.
Neural networks generate synthetic fingerprints
Fingerprint authentication systems are a widely trusted, ubiquitous form of biometric authentication, deployed on billions of smartphones and other devices worldwide. Yet a new study reveals a surprising level of vulnerability in these systems. Using a neural network trained to synthesize human fingerprints, the research team evolved a fake fingerprint that could potentially fool a touch-based authentication system for up to one in five people.
AI tool accurately identifies cancer type and genetic changes
A new computer program can analyze images of patients' lung tumors, specify cancer types, and even identify altered genes driving abnormal cell growth, a new study shows.
New sensors track dopamine in the brain for more than a year
Neuroscientists have now devised a way to measure dopamine in the brain for more than a year, which they believe will help them to learn much more about its role in both healthy and diseased brains.
Seeking a new element in artificial intelligence: trust
For decades, the cybersecurity community has devised protections to fend off malicious software attacks and identify and fix flaws that can disrupt the computing programs that are central to all aspects of life. Now, a team of researchers has received a grant to develop some of the first tools to bring those same protections to artificial intelligence systems.
Organic crystals twist, bend, and heal
Crystals are brittle and inelastic? A novel class of smart, bendable crystalline organic materials has challenged this view. Now, scientists have engineered a molecular soft cocrystalline structure that bends and twists reversibly and without disintegration when stimulated by high temperature, mechanical force, or under UV light.
Capturing brain signals with soft electronics
A new technology for long-term stable neural recording. It is based on a novel elastic material composite, which is biocompatible and retains high electrical conductivity even when stretched to double its original length.
Materials sandwich breaks barrier for flexible solar cell efficiency
Solar cells have great potential as a source of clean electrical energy, but so far they have not been cheap, light, and flexible enough for widespread use. Now a team of researchers has found an innovative and promising way to improve solar cells and make their use in many applications more likely.
Lightweight syntactic foams could help submarines dive deeper
A team of materials scientists has developed the first process to 3D print components of syntactic foam — extremely strong and lightweight composites used in vehicles, airplanes, and ships.
New CRISPR method efficiently corrects DMD defect in heart tissue
Scientists have developed a CRISPR gene-editing technique that can potentially correct a majority of the 3,000 mutations that cause Duchenne muscular dystrophy (DMD) by making a single cut at strategic points along the patient's DNA.
The robots will see you now
For more than a decade, biomimetic robots have been deployed alongside live animals to better understand the drivers of animal behavior, including social cues, fear, leadership, and even courtship. The encounters have always been unidirectional; the animals observe and respond to the robots.
Dozens of new genes that create T cell-resistant cancer discovered
To better understand why some cancers are resistant to immunotherapy, researchers collaborated on a large-scale CRISPR cancer study.
