Well if I’m not a magnet for computer issues I don’t know who is. If it’s not one computer it’s the other. In this case, I had problems a while back with my desktop (here) where the watercooler went bad and my CPU decided it wanted to scream at me anytime I ran the computer, like just turned it on, not doing anything with it. This time it’s my laptop that I’m having trouble with and unlike my desktop, the laptop is my daily use computer so I’m not too happy.(more…)
This is not the post you are looking for. Error, please try again. Okay, seriously I need to get some work done today and I don’t have time to solve our mysterious mind control device problem that I posed yesterday, so today I’m going to give some quick thoughts on something totally unrelated because there isn’t time for anything else and while trying to figure out a header for this post (where I was originally going to say hey can’t talk today) I was reminded of max headroom. I genuinely don’t know that I’ve ever said that before, but here we are…(more…)
Increasingly powerful computers using ever-more sophisticated programs are challenging human supremacy in areas as diverse as playing chess and making emotionally compelling music. But can digital diagnosticians match, or even outperform, human physicians? The answer, according to a new study, is “not quite.”
High-tech prosthetics, computers that are controlled by thought, the ability to walk or even move again, these are just a few of the promises of technology. Unfortunately, while the tech is — mostly — up to the challenge, getting the biology side of things to cooperate has been difficult at best, but that could change. Now, scientists have created a material that could make reading biological signals, from heartbeats to brainwaves, much more sensitive.
New research has demonstrated that a nanoscale device, called a memristor, could be used to power artificial systems that can mimic the human brain. Artificial neural networks (ANNs) exhibit learning abilities and can perform tasks which are difficult for conventional computing systems, such as pattern recognition, on-line learning and classification.
Typically when scientists make a measurement, they know exactly what kind of measurement they’re making, and their purpose is to obtain a measurement outcome. But in an “unrecorded measurement,” both the type of measurement and the measurement outcome are unknown.
A trio of researchers has found off-the-shelf AI software can be used to identify people in blurred or pixilated images. The researchers have uploaded a paper describing the experiments they carried out with AI software identification of people or other items in blurred out images, what they found and reveal just how accurate they found it could be.
As you relax and let your mind drift aimlessly, you might remember a pleasant vacation, an angry confrontation in traffic or maybe the loss of a loved one. And now a team of researchers say they can see those various emotional states flickering across the human brain.
Saving up excess solar and wind energy for times when the sun is down or the air is still requires a storage device. Batteries get the most attention as a promising solution although pumped hydroelectric storage is currently used most often. Now researchers are advancing another potential approach using sugar alcohols—an abundant waste product of the food industry—mixed with carbon nanotubes.
Electronics integrated into textiles are gaining in popularity: Systems like smartphone displays in a sleeve or sensors to detect physical performance in athletic wear have already been produced. The main problem with these systems tends to be the lack of a comfortable, equally wearable source of power. Chinese scientists are now aiming to obtain the necessary energy from body heat by introducing a flexible, wearable thermocell based on two different gel electrolytes.
Can life be brought to celestial bodies outside our solar system, which are not permanently inhabitable? A new essay that has been published is trying to deal with this question. Over the last several years, the search for exoplanets has shown that very different types exist leading to new questions and a variety of possible answers.
Death and mourning were largely considered private matters in the 20th century, with the public remembrances common in previous eras replaced by intimate gatherings behind closed doors in funeral parlors and family homes. But social media is redefining how people grieve, and Twitter in particular — with its ephemeral mix of rapid-fire broadcast and personal expression — is widening the conversation around death and mourning.
In this digital age, with phones at our fingertips, you would think that access to constant communication would make us feel closer to one another. But a new study shows that may not be the case. In fact, cell phone use might actually lead to feeling less socially connected, depending on your gender or cell phone habits.
Conducted at the BioMag laboratory at the Helsinki University Hospital, a new patient study could open a new opportunity to rehabilitate patients with spinal cord damage. In a new study which two patients with spinal cord injuries received a form of treatment that combined transcranial magnetic stimulation with simultaneous peripheral nerve stimulation given repeatedly for nearly six months.
Move over silicon, tomorrow’s computers could be made of something completely different. A team of international researchers managed to find a molecule that, to their opinion, could give the impetus to the development of organic electronics.
The new stem cell-containing bio ink allows 3D printing of living tissue, known as bio-printing. The new bio-ink contains two different polymer components: a natural polymer extracted from seaweed, and a sacrificial synthetic polymer used in the medical industry, and both had a role to play.
Countries that implement government-mandated vaccinations for chickenpox see a sharp drop in the number of Google searches for the common childhood disease afterward, demonstrating that immunization significantly reduces seasonal outbreaks. That’s one of the findings from a new study that analyzed thousands of Google searches for “chickenpox.”
Tablet and laptop users beware. Using digital platforms such as tablets and laptops for reading may make you more inclined to focus on concrete details rather than interpreting information more abstractly, according to a new study. The findings serve as another wake-up call to how digital media may be affecting our likelihood of using abstract thought.
A pioneering study of worldwide sleep patterns combines math modeling, mobile apps and big data to parse the roles society and biology each play in setting sleep schedules. The study used a free smartphone app that reduces jetlag to gather robust sleep data from thousands of people in 100 nations. The researchers examined how age, gender, amount of light and home country affect the amount of shut-eye people around the globe get, when they go to bed, and when they wake up.
Happiness. It’s something we all strive for, but how do we measure it — as a country? A global community? Not so surprisingly, researchers are turning to social media to answer these questions and more. In a newly published study, computer scientists used two years of Twitter data to measure users’ life satisfaction, a component of happiness.
As a society we have become incredibly reliant on technology, from spell check to GPS, we are slowly being replaced by computers. Need more proof, a computer can routinely beat us at chess, an AI wrote portions of a book that went on to almost win a writing contest, and if you want scary robotics enter Boston dynamics spot. So the question is, have we outlived our place in the world? Not quite. Welcome to the front line of research in cognitive skills, quantum computers and gaming.
Last month, we spoke of our vision of the future of humanity here at the lab. It makes sense that humanity would one-day step away from the static, non-living computer constructs we have designed. Moving us instead towards an organic alternative, one that can be readily repaired, replaced, or changed. While we cannot pretend to know what the future may hold, a new discovery helps bolster the stance we presented.
Rustling leaves, a creaking branch: To a mouse, these sensory impressions may, at first, seem harmless — but not if a cat suddenly bursts out of the bush. If so, they were clues of impending life-threatening danger. Researcher Robert Gütig has now found how the brain can link sensory perceptions to events occurring after a delay.
“I know kung fu,” movie buffs might remember the remember the quote from “The Matrix.” We can all probably agree that being able to download knowledge “on tap” would be a boon to humanity. It is a shame it is just a movie… right? While that may be the case, it is just for now. That is because researchers have discovered that low-current electrical brain stimulation can modulate the learning of complex real-world skills.
Using a sophisticated, custom-designed 3D printer, regenerative medicine scientists at Wake Forest Baptist Medical Center have proved that it is feasible to print living tissue structures to replace injured or diseased tissue in patients. Scientists said they printed ear, bone and muscle structures. When implanted in animals, the structures matured into functional tissue and developed a system of blood vessels.
Scientists at the UCLA Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research and Center for Duchenne Muscular Dystrophy at UCLA have developed a new approach that could eventually be used to treat Duchenne muscular dystrophy. The stem cell gene therapy could be applicable for 60 percent of people with Duchenne, which affects approximately 1 in 5,000 boys in the U.S. and is the most common fatal childhood genetic disease.
As we continue to shrink electronic components, top-down manufacturing methods begin to approach a physical limit at the nanoscale. Rather than continue to chip away at this limit, one solution of interest involves using the bottom-up self-assembly of molecular building blocks to build nanoscale devices.
Thanks to the Internet, amateur volunteers known as “citizen scientists” can readily donate their time and effort to science–in fields ranging from medicine to zoology to astrophysics. The astrophysics project Space Warps offers a compelling example of why citizen science has become such a popular tool and how valuable it can be.
In “Star Trek”, a transporter can teleport a person from one location to a remote location without actually making the journey along the way. Such a transporter has fascinated many people. Quantum teleportation shares several features of the transporter and is one of the most important protocols in quantum information.
The constant barrage of post-holiday sales touted by web-based retailers may make it seem like online shopping is killing real-world stores. But shoppers are actually engaging in “web-to-store” shopping — buying offline after comparing prices online.
Scientists showed that they could alter brain activity of rats and either wake them up or put them in an unconscious state by changing the firing rates of neurons in the central thalamus, a region known to regulate arousal. The study was partially funded by the National Institutes of Health.
Researchers are proposing a new “hydricity” concept aimed at creating a sustainable economy by not only generating electricity with solar energy but also producing and storing hydrogen from superheated water for round-the-clock power production.
Why send a message back in time, but lock it so that no one can ever read the contents? Because it may be the key to solving currently intractable problems. It turns out that an unopened message can be exceedingly useful. This is true if the experimenter entangles the message with some other system in the laboratory before sending it.
A new, open-source software that can help track the embryonic development and movement of neuronal cells throughout the body of the worm, is now available to scientists.
Substantially smaller and longer-lasting batteries for everything from portable electronic devices to electric cars could become a reality thanks to an innovative technology developed by University of Waterloo researchers. Zhongwei Chen, a chemical engineering professor at Waterloo, and a team of graduate students have created a low-cost battery using silicon that boosts the performance and life of lithium-ion batteries.
Scientists at Washington State University and the University of Idaho are helping students figure out how to farm on Mars, much like astronaut Mark Watney, played by Matt Damon, attempts in the critically acclaimed movie “The Martian.” Washington State University physicist Michael Allen and University of Idaho food scientist Helen Joyner teamed up to explore the challenge. Their five-page study guide was published the day the movie premiered earlier this month.
Researchers at USC and Wake Forest Baptist Medical Center have developed a brain prosthesis that is designed to help individuals suffering from memory loss. The prosthesis, which includes a small array of electrodes implanted into the brain, has performed well in laboratory testing in animals and is currently being evaluated in human patients.
A team including the scientist who first harnessed the revolutionary CRISPR-Cas9 system for mammalian genome editing has now identified a different CRISPR system with the potential for even simpler and more precise genome engineering. In the study researchers describe the unexpected biological features of this new system and demonstrate that it can be engineered to edit the genomes of human cells.
Social networking makes it easy to monitor the status and activities of a former romantic partner, an often unhealthy use of social media known as interpersonal electronic surveillance (IES) or, more commonly, “Facebook stalking.” Psychological and relationship factors and how individuals cope with the termination of a romantic relationship can help predict their use of online surveillance, according to a new study.
It’s not lightsaber time… at least not yet. But a team including theoretical physicists from the National Institute of Standards and Technology (NIST) has taken another step toward building objects out of photons, and the findings* hint that weightless particles of light can be joined into a sort of “molecule” with its own peculiar force.
An experiment to determine the effects of positive and negative user comments to items posted by media organizations on Facebook news channels showed, surprisingly, that the influence of user comments varied depending on the type and number of user comments. Negative comments influenced the persuasiveness of a news article, while positive comments did not, and a high number of likes did not have the expected bandwagon effect.
Wikipedia reigns. It’s the world’s most popular online encyclopedia, the sixth most visited website in America, and a research source most U.S. students rely on. But Wikipedia entries on politically controversial scientific topics can be unreliable due to information sabotage.
The practice of sexting may be more common than generally thought among adults. More than eight out of 10 people surveyed online admitted to sexting in the prior year, according to new research.
Five men with complete motor paralysis were able to voluntarily generate step-like movements thanks to a new strategy that non-invasively delivers electrical stimulation to their spinal cords. The strategy, called transcutaneous stimulation, delivers electrical current to the spinal cord by way of electrodes strategically placed on the skin of the lower back.
