Chinese AI-powered robot Xiaoyi took the country’s medical licensing examinations and passed, according to local reports. Xiaoyi is just one example of how much China is keen on using AI to make a number of industries more efficient.
Experts generally agree that, before we might consider artificial intelligence (AI) to be truly intelligent —that is, on a level on par with human cognition— AI agents have to pass a number of tests. And while this is still a work in progress, AIs have been busy passing other kinds of tests.
Researchers at the University of California Los Angeles have figured out a way to generate strikingly detailed 3D reconstructing of platinum nanoparticles at the very atomic scale. These are being used to study minute structural anomalies called dislocations. You can read the research paper here. Watch the video below for more.[no-sidebar].
Stanford researchers have developed an algorithm that offers diagnoses based off chest X-ray images. It can diagnose up to 14 types of medical conditions and is able to diagnose pneumonia better than expert radiologists working alone.
A paper about the algorithm, called CheXNet, was published Nov. 14 on the open-access, scientific preprint website arXiv.
“Interpreting X-ray images to diagnose pathologies like pneumonia is very challenging, and we know that there’s a lot of variability in the diagnoses radiologists arrive at,” said Pranav Rajpurkar, a graduate student in the Machine Learning Group at Stanford and co-lead author of the paper. “We became interested in developing machine learning algorithms that could learn from hundreds of thousands of chest X-ray diagnoses and make accurate diagnoses.”
Multiband tunable antennas are a critical part of many communication and radar systems. New research by engineers at the University of Bristol has shown significant advances in antennas by using optically induced plasmas in silicon to tune both radiation patterns and operation frequency.
Conventional antenna tuning is performed with diodes or Micro-Electro-Mechanical Systems (MEMS) switches. However, these approaches have significant drawbacks as systems become more complex and move to higher frequencies, which is anticipated for 5G systems.
The first paper, published in IET Optoelectronics, co-authored by Dr Chris Gamlath, Research Associate in RF Engineering during his PhD, shows how a silicon superstrate placed over a slotted microstrip patch can be used to tune radiation patterns.
Biologist Mark Roth, at Seattle’s Fred Hutchinson Cancer Research Center, is working with animal subjects, putting them into suspended animation. The idea is that a patient who is in medical crisis could be put into a suspended state like hibernation, until he or she could be stabilized and in this way, get past it.
Though we tend to expire when the oxygen level is low, many animals go into a suspended state in extremely low oxygen environments. In the lab, one must enter into such an environment quickly. Roth is currently working with nematodes—a kind of roundworm—and expects to eventually work up to humans.
A vegetative state is another aspect of what we consider the gray zone between life and death. Medically, this is when sufficient damage to the brain has occurred, where the person isn’t aware of and can’t respond to their surroundings. They may breathe, have a heartbeat, move their eyes, even show reflexes, but they can’t respond to stimuli or interact with the world. Their brain stem is operating normally, but other parts of the brain may be damaged or inoperable. Most patients who enter such a state never leave it.
Portable hard drives seem like they’re bound to go way of the dinosaur, thanks to the rise of services like Dropbox and Google Drive. But if you wanted to take a large file home with you back in 1985, you didn’t have quite so many options. Your best bet? Maybe this hard drive from Maynard.
“Leave the computer, take the drive!” the ad said in big, bold letters in the July 1985 issue of Byte magazine. And look at just how portable that thing is!
