Artificial Intelligence research at Duke covers everything from health to enhancing photos to machine learning. See what some Duke researchers are doing in the field. During Winter Breakaway, David Carlson, an assistant professor in Civil and Environmental Engineering taught "AI for Everyone," which included an introduction to the math and computations underlying machine learning and artificial intelligence. Duke student brothers worked together in a home office in Tampa to develop a machine learning system to help clinicians spot the telltale'ground glass opacities' in the lung scans of potential Covid patients. Because no two brains are alike, machine learning is being used to help neurosurgeons home in on the precise area where the electrode should go to treat Parkinson's disease with deep brain stimulation.
Substituting a cup of cocoa throughout the day for other snacks could help obese people lose weight – even if they're on a high-fat diet, a new study claims. In lab experiments, US researchers gave obese mice with liver disease a dietary supplement of cocoa powder, for a period of eight weeks. Even though the mice were on a high-fat diet, the experts found the supplement reduced DNA damage and the amount of fat in their livers. While there is more to learn about the health benefits of cocoa, the researchers believe it may in some way impede the digestion of dietary fat and carbohydrate, thereby avoiding weight gain. Supplementation of cocoa powder in the diet of high-fat-fed mice with liver disease markedly reduced the severity of their condition, according to a new study.
Data Science is rapidly growing to occupy all the industries of the world today. In this topic, we will understand how data science is transforming the healthcare sector. We will understand various underlying concepts of data science, used in medicine and biotechnology. Medicine and healthcare are two of the most important part of our human lives. Traditionally, medicine solely relied on the discretion advised by the doctors. For example, a doctor would have to suggest suitable treatments based on a patient's symptoms.
A really significant change in brain science in recent years has been the gradual acceptance in mainstream science venues of sympathy for panpsychism -- the position that everything is conscious to some degree. Leading neuroscientist Christof Koch, for example, explained last month in MIT Reader: But who else, besides myself, has experiences? Because you are so similar to me, I abduce that you do. The same logic applies to other people. Apart from the occasional solitary solipsist this is uncontroversial.
An analysis of electronic health records for 1.7 million Wisconsin patients revealed a variety of health problems newly associated with fragile X syndrome, the most common inherited cause of intellectual disability and autism, and may help identify cases years in advance of the typical clinical diagnosis. Researchers from the Waisman Center at the University of Wisconsin–Madison found that people with fragile X are more likely than the general population to also have diagnoses for a variety of circulatory, digestive, metabolic, respiratory, and genital and urinary disorders. Their study, published recently in the journal Genetics in Medicine, the official journal of the American College of Medical Genetics and Genomics, shows that machine learning algorithms may help identify undiagnosed cases of fragile X syndrome based on diagnoses of other physical and mental impairments. "Machine learning is providing new opportunities to look at huge amounts of data," says lead author Arezoo Movaghar, a postdoctoral fellow at the Waisman Center. "There's no way that we can look at 2 million records and just go through them one by one. We need those tools to help us to learn from what is in the data."
Elon Musk's brain-implant lab, Neuralink, today released video appearing to show something the tech billionaire has been bragging about since 2019: a monkey playing a video game ... with its mind. In the video (and an accompanying one of the Neuralink signal readout, if you're into that), a rhesus macaque named Pager is shown playing simple games on a screen while sucking on a straw that's delivering a tasty banana smoothie as a reward. Pager, at first, uses a joystick to move a dot around a grid, placing it onto squares that light up one by one at random. In the next sequence, he's still using the joystick -- but as the gently British-accented narrator points out, the joystick apparatus is quite clearly unplugged. The implant, we're told, is transmitting data from the electrical signals his brain emits as he plays.
Elon Musk's last update on Neuralink -- his company that is working on technology that will connect the human brain directly to a computer -- featured a pig with one of its chips implanted in its brain. Now Neuralink is demonstrating its progress by showing a Macaque with one of the Link chips playing Pong. At first using "Pager" is shown using a joystick, and then eventually, according to the narration, using only its mind via the wireless connection. Monkey plays Pong with his mind https://t.co/35NIFm4C7T Today we are pleased to reveal the Link's capability to enable a macaque monkey, named Pager, to move a cursor on a computer screen with neural activity using a 1,024 electrode fully-implanted neural recording and data transmission device, termed the N1 Link.
Algorithms similar to those used by Netflix, Amazon and Facebook have shown the ability to decipher the'biological language' of cancer, Alzheimer's and other neurodegenerative diseases. Researchers trained a large-scale language model with a recommendation AI to look at what happens when something goes wrong with proteins that leads to the development of a disease. The work, conducted by St. John's College and the University of Cambridge, programed the algorithm to learn the language of shapeshifting droplets of proteins found in cells in order to understand their function and malfunction. By learning these protein droplets' language, the team can then'correct the grammatical mistakes inside cells that cause disease.'' Professor Tuomas Knowles, a Fellow at St John's College, said: 'Any defects connected with these protein droplets can lead to diseases such as cancer. 'This is why bringing natural language processing technology into research into the molecular origins of protein malfunction is vital if we want to be able to correct the grammatical mistakes inside cells that cause disease.' Machine learning technology has made waves in the tech industry – Netflix uses it to recommend series, Facebook's suggest someone to friend and Amazon's Alexa has an algorithm to recognize people based on their voice.
Powerful algorithms used by Netflix, Amazon and Facebook can'predict' the biological language of cancer and neurodegenerative diseases like Alzheimer's, scientists have found. Big data produced during decades of research was fed into a computer language model to see if artificial intelligence can make more advanced discoveries than humans. Academics based at St John's College, University of Cambridge, found the machine-learning technology could decipher the'biological language' of cancer, Alzheimer's, and other neurodegenerative diseases. Their ground-breaking study has been published in the scientific journal PNAS today and could be used in the future to'correct the grammatical mistakes inside cells that cause disease'. Professor Tuomas Knowles, lead author of the paper and a Fellow at St John's College, said: "Bringing machine-learning technology into research into neurodegenerative diseases and cancer is an absolute game-changer. Ultimately, the aim will be to use artificial intelligence to develop targeted drugs to dramatically ease symptoms or to prevent dementia happening at all."
As research involving transplanting lab-grown human'mini-brains' into animals to study neurological diseases continues to expand, experts warn the work with these brain organoids could result in a'Planet of the Apes' scenario. The concern is animals could develop humanized traits and start to behave similar to the intelligent apes of the popular science fiction story. The warning comes from a team at Kyoto University who released a paper highlighting a number of ethical implications that could arise with brain organoid research. Although many see brain organoids as a way to quickly develop disease treatments, others fear that because they are designed to mimic the real thing, they too may attain some form of consciousness. Experts warn the work with these brain organoids could result in a'Planet of the Apes' (pictured) scenario.
