Normally, it takes pricey equipment and expertise to create an accurate 3D reconstruction of someone's face. Now, Carnegie Mellon University researchers have pulled off the feat using video recorded on an ordinary smartphone. Shooting a continuous video of the front and sides of the face generates a dense cloud of data. A two-step process developed by CMU's Robotics Institute uses that data, with some help from deep learning algorithms, to build a digital reconstruction of the face.
A team of cybersecurity researchers has discovered that a large number of cell phone applications contain hardcoded secrets allowing others to access private data or block content provided by users. The study's findings: that the apps on mobile phones might have hidden or harmful behaviors about which end users know little to nothing.
A team of medical researchers and bioethicists at Oxford University has published results today in Science that furthers our understanding of coronavirus transmission. This evidence is enabling several international partners to assess the feasibility of developing mobile apps for instant contact tracing in record time. If rapidly and widely developed, these mobile apps could help to significantly slow the rate of transmission, and support countries to emerge from lockdowns safely, as restrictions are gradually eased.
Researchers from the Quantum Optomechanics group at the Niels Bohr Institute, University of Copenhagen, recently entangled two laser beams through bouncing them off the same mechanical resonator, a tensioned membrane. This provides a novel way of entangling disparate electromagnetic fields, from microwave radiation to optical beams. Creating entanglement between optical and microwave fields would be a key step towards solving the challenge of sharing entanglement between two distant quantum computers operating in the microwave regime.
Researchers have demonstrated a new model of how competing pieces of information spread in online social networks and the Internet of Things (IoT). The findings could be used to disseminate accurate information more quickly, displacing false information about anything from computer security to public health.
Sorting through millions of possibilities, a search for battery materials delivered results in five weeks instead of 50 years.
Artificial intelligence will be increasingly used on labels on food and other products in the future to make them interactive, and regulations should be reformed now so they take account of new innovations, a study warns.
Differences between whole body and body part ownership were clarified using scrambled body stimulation in a virtual environment, wherein the observer's hands and feet were presented in randomized spatial arrangements. While moving, the scrambled body stimulation produces a sense of possession of limbs (hands and feet), but possession of the whole body cannot be grasped. Spatial placement is important for the illusion of whole-body ownership. Bodily self-consciousness is thus affected by the body's spatial arrangement.
A simulation system invented at MIT to train driverless cars creates a photorealistic world with infinite steering possibilities, helping the cars learn to navigate a host of worse-case scenarios before cruising down real streets.
A new method to accurately record brain activity at scale has been developed by researchers at the Crick, Stanford University and UCL. The technique could lead to new medical devices to help amputees, people with paralysis or people with neurological conditions such as motor neurone disease.
