Anesthestic drugs act on the brain but most anesthesiologists rely on heart rate, respiratory rate, and movement to infer whether surgery patients remain unconscious to the desired degree. In a new study, a research team based at MIT and Massachusetts General Hospital shows that a straightforward artificial intelligence approach, attuned to the kind of anesthetic being used, … [Read more...] about Algorithms show accuracy in gauging unconsciousness under general anesthesia

Hologram experts can now create real-life images that move in the air: Using lasers to create the displays of science fiction, inspired by Star Wars and Star Trek
They may be tiny weapons, but Brigham Young University's holography research group has figured out how to create lightsabers -- green for Yoda and red for Darth Vader, naturally -- with actual luminous beams rising from them. Inspired by the displays of science fiction, the researchers have also engineered battles between equally small versions of the Starship Enterprise and a … [Read more...] about Hologram experts can now create real-life images that move in the air: Using lasers to create the displays of science fiction, inspired by Star Wars and Star Trek
Evading the uncertainty principle in quantum physics: New technique gets around 100-year-old rule of quantum physics for the first time
The uncertainty principle, first introduced by Werner Heisenberg in the late 1920's, is a fundamental concept of quantum mechanics. In the quantum world, particles like the electrons that power all electrical product can also behave like waves. As a result, particles cannot have a well-defined position and momentum simultaneously. For instance, measuring the momentum of a … [Read more...] about Evading the uncertainty principle in quantum physics: New technique gets around 100-year-old rule of quantum physics for the first time
When algorithms go bad: How consumers respond
Researchers from University of Texas-Austin and Copenhagen Business School published a new paper in the Journal of Marketing that offers actionable guidance to managers on the deployment of algorithms in marketing contexts. The study, forthcoming in the Journal of Marketing, is titled "When Algorithms Fail: Consumers' Responses to Brand Harm Crises Caused by Algorithm Errors" … [Read more...] about When algorithms go bad: How consumers respond
SMART evaluates impact of competition between autonomous vehicles and public transit
The rapid advancement of Autonomous Vehicles (AV) technology in recent years has changed transport systems and consumer habits globally. As countries worldwide see a surge in AV usage, the rise of shared Autonomous Mobility on Demand (AMoD) service is likely to be next on the cards. Public Transit (PT), a critical component of urban transportation, will inevitably be impacted … [Read more...] about SMART evaluates impact of competition between autonomous vehicles and public transit
An uncrackable combination of invisible ink and artificial intelligence
Coded messages in invisible ink sound like something only found in espionage books, but in real life, they can have important security purposes. Yet, they can be cracked if their encryption is predictable. Now, researchers reporting in ACS Applied Materials & Interfaces have printed complexly encoded data with normal ink and a carbon nanoparticle-based invisible ink, … [Read more...] about An uncrackable combination of invisible ink and artificial intelligence
Physicists find a novel way to switch antiferromagnetism on and off: The findings could lead to faster, more secure memory storage, in the form of antiferromagnetic bits
When you save an image to your smartphone, those data are written onto tiny transistors that are electrically switched on or off in a pattern of "bits" to represent and encode that image. Most transistors today are made from silicon, an element that scientists have managed to switch at ever-smaller scales, enabling billions of bits, and therefore large libraries of images and … [Read more...] about Physicists find a novel way to switch antiferromagnetism on and off: The findings could lead to faster, more secure memory storage, in the form of antiferromagnetic bits
New graphite-based sensor technology for wearable medical devices
Researchers at AMBER, the SFI Centre for Advanced Materials and BioEngineering Research, and from Trinity's School of Physics, have developed next-generation, graphene-based sensing technology using their innovative G-Putty material. The team's printed sensors are 50 times more sensitive than the industry standard and outperform other comparable nano-enabled sensors in an … [Read more...] about New graphite-based sensor technology for wearable medical devices
Loan applications processed around midday more likely to be rejected
Bank credit officers are more likely to approve loan applications earlier and later in the day, while 'decision fatigue' around midday is associated with defaulting to the safer option of saying no. These are the findings of a study by researchers in Cambridge's Department of Psychology, published today in the journal Royal Society Open Science. Decision fatigue is the … [Read more...] about Loan applications processed around midday more likely to be rejected
New algorithm uses a hologram to control trapped ions
Researchers have discovered the most precise way to control individual ions using holographic optical engineering technology. The new technology uses the first known holographic optical engineering device to control trapped ion qubits. This technology promises to help create more precise controls of qubits that will aid the development of quantum industry-specific hardware to … [Read more...] about New algorithm uses a hologram to control trapped ions
