At the intersection of neuroscience and artificial intelligence (AI) is an alternative approach to deep learning. Evolutionary algorithms (EA) are a subset of evolutionary computation—algorithms that mimic biological evolution to solve complex problems. Published this week on Tuesday in Cell Reports, IBM researchers took an innovative approach using evolutionary algorithms to create a state-of-the-art cloud-based neuroscience model for studying neurodegenerative disorders. The origins of artificial intelligence goes back to the 1950s. The recent global resurrection of AI from its hibernation is largely due to advances in machine learning pattern recognition, namely deep learning. Deep learning,
Summary: Using a statistical mechanics framework, researchers gain insight into why basic ordered patterns emerge in music and uncover emergent structures of musical harmony. Source: Case Western Reserve University Next time you listen to a favorite tune or wonder at the beauty of a natural sound, you might also end up pondering the math behind the music. You will, anyway, if you spend any time talking with Jesse Berezovsky, an associate professor of physics at Case Western Reserve University. The longtime science researcher and a part-time viola player has become consumed with understanding and explaining the connective tissue between the two disciplines–more specifically, how the ordered structure
(Inside Science) -- As the ball dropped in Times Square this New Year's Eve, the New Horizons spacecraft was fast approaching an approximately 20-mile-long space rock nicknamed Ultima Thule, located a whopping 4 billion miles from Earth. As the spacecraft zipped past the tiny world, it deployed a suite of seven scientific instruments to gather a treasure trove of images and measurements, which it has been slowly sending back to Earth for months. The data dumps will continue until the summer of 2020, but today scientists published their latest findings, based on the 10% of the captured data that had been transferred by March 1. Overall, the new findings paint a vivid picture of a tiny, cold and
The molecular identity and precise function of a commonly expressed cell-membrane chloride channel has long been a mystery. A recent study in Science uncovers the gene responsible for the channel, potentially shedding light on its role in the body. Researchers dubbed the gene PAC for proton activated chloride channel. “Now that there's a genetic handle on this ion channel,” says research and clinical neuroscientist John Wemmie at the University of Iowa in Iowa City, “it's sort of off to the races.” Two decades ago, another group of ion channels had a similar story, he says. They were believed to play a role in the pain caused by acidifying tissue in inflammatory conditions. Beyond that, they
The project launched by the U.S. National Aeronautics and Space Administration (NASA) for its Mars mission in 2020 has drawn great attention on social media. Turkey, on the other hand, ranked first in the list of countries interested in the "Send Your Name to Mars" campaign initiated by NASA. Some 308,454 people from Turkey have so far applied to NASA to send their names to Mars. In 2020, NASA will send a new Rover spacecraft to Mars, our nearest neighbor in the Solar system. NASA has launched a campaign called "Send Your Name to Mars" with the aim of making space enthusiasts a part of the mission. Thanks to this campaign, those who visit the web page will fill out a form, and their names will
Up until now it was believed that various organs and structures float in cytoplasm inside a cell. Scientists thought that messages through the cells are transferred via waves. However, this understanding is quickly changing as scientists from the University of Edinburgh discovered a cell-wide web – a communication network constructed from guide wires that transmit signals across nanoscale distances. Scientists say that this means that there is a circuit board inside every cell, but it is not fixed in its structure like computer boards. Instead, they are rewired to change the behaviour of the cells. Scientists say that there is a huge network of guide wires, which is guiding charged molecules
Space isn't empty; it's crowded. And what goes up there, might not come back down. Everyone knows that NASA sends science instruments into space, but since the late 1950s, the United States, Russia, China, and lots of other countries have launched thousands of satellites including science satellites, telecommunication satellites, GPS satellites and spy satellites, which orbit at low, medium or high altitudes. These satellites don't last forever, not even the highest-quality ones. The hardware eventually runs out of fuel or the battery dies or the system simply breaks down after a while. And that's not all. There's old boosters, ballistic missiles left over from testing warheads, insulation, paint
Meanwhile younger males have a harder time enticing females back to their burrows -- but more mating happens if they succeed. University of Exeter scientists studied field crickets to see if a male's age affected how attractive females found them. "Females choose mates to get the best genes for their offspring," said Dr Rolando Rodríguez-Muñoz of the Centre for Ecology and Conservation on the University of Exeter's Penryn Campus in Cornwall. "It's possible that the oldest males have the best genes because they've shown they can live for a long time.¬ "On the other hand, females might favour younger males whose sperm have not accumulated possibly harmful mutations that will be passed on to offspring.
Let's Stop Going in Circles - And Go Somewhere (2002). "Between the time I was 2 and when I turned 14 humanity went from zero spaceflight capability to putting humans on the Moon. To me, my first vision of spaceflight was one where quantum leaps were to be expected. I knew this because I saw these leaps happening before my own eyes. That expectation took a firm hold of me and hasn't left me - or many of my generation. Yet we, and the generation that has followed us, have been cheated of what could have been done in space. In the following three decades we have yet to send humans back to the Moon. Indeed, it would probably take us longer to recreate the ability to "land humans on the Moon and
HIGHLANDS RANCH, Colo. (CBS4) -The land before time is closer than you think. Dinosaur fossils were discovered last week at a construction site near Wind Crest at Santa Fe Drive and C-470. A paleontology dig conducted by the Denver Museum of Nature and Science has since unearthed several more bones. CBS4 got an exclusive look at their progress Thursday morning. “We've uncovered a number of ribs. We found a lower leg bone, tibia, upper leg bone, humerus. We think we have parts of the dinosaur's skull,” said Natalie Toth, chief fossil preparator. It's too soon to say what type of dinosaur this was, but right not the experts believe it was a horned dinosaur. It's likely something similar to a triceratops
What's in a name? Well, for the amateur astronomers and scientists fixated on Jupiter, there's been a recent need to describe its iconic storm as more than just a great red spot. Here on Earth, storms are born and then they disappear. And though it has lingered for hundreds of years, Jupiter's famous vortex may be approaching the end of its life span, too, as strange as that may seem. The Great Red Spot — GRS for short — is getting smaller. The system was once very elongated, which NASA scientist Glenn Orton joked "might have been better referred to as the Great Red Sausage" in a May 21 email to Space.com. Orton added that the GRS has been shrinking at a pretty consistent rate. Recently, amateur
Kansas museum sends restored NASA consoles home to Texas Mission control consoles used by NASA to guide trips to the moon are being restored by experts in Kansas and will soon be returned to the control room in Houston, Texas, where they were used from the 1960s through the 1990s. SpaceWorks specializes in the restoration and replication of spacecraft and space artifacts, and is affiliated with Cosmosphere, the space museum and STEM education center in Hutchinson, Kansas. Spaceworks crews have restored 19 NASA mission control consoles over the last year and a half, the Hutchinson News reported. NASA picked up 10 of the consoles last year, and the remainder will be sent to the Johnson Space Center
NASA is planning on sending the first woman ever and the first man in nearly five decades to the moon by 2024, thanks to an additional increase to the agency's budget by President Trump. Only 12 humans, all male, have ever walked on the moon and they were all American, according to Bettina Inclán, NASA Communications Director. All 12 men were Americans. "The last person walked on the Moon in 1972," Inclán told CNN in a statement. "No woman has ever walked on the lunar surface." Trump announced Monday that he is adding $1.6 billion to NASA's budget "so that we can return to Space in a BIG WAY!" "Under my Administration, we are restoring @NASA to greatness and we are going back to the Moon, then
In Bernard Malamud's The Natural, Iris (played in the movie version by Glenn Close) tells Roy Hobbs that we all have two lives, “the life we learn with and the life we live with after that.” Murray Gell-Mann, the Nobel laureate physicist who died Friday, May 24, at age 89, also lived two lives. But both were spent learning — about how the world works. In his first life Gell-Mann was perhaps the preeminent theoretical physicist of his era, playing a prime role in revealing the architecture of the subatomic world. In his second life he pioneered the study of complexity, probing the behavior of systems ranging from economics to the weather, too complicated for the reductionist methods of particle
In fact, the animal's genetic diversity is lower than that of any other wild mammal whose genome has been genetically sequenced. Low genetic diversity is primarily found among highly endangered species such as, for instance, the mountain gorilla. Population numbers for the alpine marmot, however, are in the hundreds of thousands, which is why the species is not considered to be at risk," explains Prof. Dr. Markus Ralser, the Director of Charité's Institute of Biochemistry and the investigator with overall responsibility for the study, which was co-led by the Francis Crick Institute. As the alpine marmot's low genetic diversity could not be explained by the animal's current living and breeding habits, the researchers used computer-based analysis to reconstruct the marmot's genetic past.
